Synlogic Announces Synthetic Biotic for Gout Developed in Partnership with Ginkgo Bioworks – PR Newswire

Posted: August 14, 2022 at 2:49 am

SYNB2081 is the second clinical drug candidate developed through the partnership between Ginkgo and Synlogic

CAMBRIDGE, Mass. and BOSTON, Aug. 11, 2022 /PRNewswire/ -- Synlogic, Inc. (Nasdaq: SYBX), a clinical-stage biotechnology company developing medicines for metabolic and immunological diseases through its proprietary approach to synthetic biology, today announced a new drug candidate for the treatment of gout developed in partnership with Ginkgo Bioworks (NYSE: DNA), the leading horizontal platform for cell programming. The new candidate, SYNB2081, is a Synthetic Biotic and is the second product to advance to clinical development through a research collaboration between Synlogic and Ginkgo, following the investigational new drug candidate SYNB1353 for the potential treatment of homocystinuria (HCU).

Gout is a complex form of inflammatory arthritis that occurs when excess uric acid in the body forms crystals in the joints. Patients experience symptoms such as intense joint pain, inflammation and redness, and limited range of motion in the affected joints. Current treatment options present limitations in both safety and efficacy, highlighting a need for new approaches. In addition, gout is a recognized risk factor in chronic kidney disease. SYNB2081 is a Synthetic Biotic designed to lower uric acid.

"With our second drug candidate into clinical development, this not only demonstrates the value of combining Ginkgo's platform with our Synthetic Biotic platform, but also highlights the potential to develop Synthetic Biotics across a range of diseases, giving us the potential to provide meaningful new treatment options to patients in need," said Dr. David Hava, Chief Scientific Officer, Synlogic.

SYNB2081 is named after one of the largest and best-preserved Tyrannosaurus rex specimens in the world. Nicknamed "Sue," the specimen is housed at the Field Museum in Chicago and is officially named FMNH PR 2081. Data from "Sue" suggests that dinosaurs like the Tyrannosaurus rex suffered from gout much in the same way as other reptiles and birds do.

"The advancement of SYNB2081 and SYNB1353 are clear indicators of the transformative platform Synlogic has created to develop new Synthetic Biotics through synthetic biology," said Patrick Boyle, Head of Codebase for Ginkgo. "We're honored to work with the Synlogic team in this pioneering next step to potentially help patients living with gout. As we've seen the Synlogic pipeline develop over the past year, we're eager to continue supporting Synlogic in generating additional therapeutic candidates."

THE SAD STORY OF THE REJECTION OF SCIENCE – Sp Supplements – DAWN.COM – DAWN.com

SCIENCE matters. Many yearn for science-free times when wars were fought with swords by valiant Ertugrul-like horsemen. Quite a few want still earlier riyasats. But I have yet to meet a fellow Pakistani willing to have a bad tooth pulled out without anaesthesia or who sends emissaries instead of using a cellphone.

These days, electricity and gas loadshedding have triggered a collective nervous breakdown, while the price of petrol is all that people talk about. All of this would be utterly incomprehensible to those who lived a mere hundred years ago. Ancient civilisations had nothing even remotely similar to the science that exists today.

Like it or not, all modern science that which is rapidly changing our world on a day-to-day basis is the 400-year-old child of European modernity. Although many civilisations Egyptian, Babylonian, Chinese, Indian, Greek and Arabian (chronologically ordered) helped create that science, not enough was known earlier to create an overarching picture of a universe run by physical law. Nor did earlier civilisations use science to create functional technologies like we do today. Instead, significant advances in ancient science came from men of genius following scholarly interests rather than economic ends.

But now that civilisation on earth has become science-based, the pursuit of science is systematic and relentless. Every country is rushing to acquire mastery over it and, even more, to use it to create technologies to fulfil social desires. Although science and technology (S&T) are two different worlds, the boundary between them has blurred with time. For example, learning how cells divide was considered pure science in the 1800s. Today, it is crucial to discovering cures for cancer.

There is little appreciation in Pakistan for the centrality of science in every modern economic pursuit. Pervez Hoodbhoy deplores the degradation of our scientific capabilities and wonders whether we can change our worldview.

An attempt to situate Pakistans S&T may be made using two different lenses; to compare todays situation with what existed in 1947 (and even earlier); and to draw parallels between Pakistan and other countries in the region. As a starting point, I will take the advent of modern education in India (as opposed to traditional education) because that is where the bifurcation between modern and conventional ways of life began.

Pre-partition situation

India during the Mughal rule saw spectacular achievements in architecture, art and administrative matters. But there was little curiosity in matters of the intellect, particularly science and philosophy. As a result, no university was built in those three centuries of otherwise brilliant rule. Although internal feuds and succession issues were doubtless a significant cause of decline, this lack of interest in intellectual pursuits eventually led to 40-50,000 Englishmen, armed with technology and the scientific method, overpowering and crushing what had been a magnificent empire. Few understood the secret source of English power better than Mirza Ghalib. Differing from those who craved a return to past glories or who suggested picking up arms against the firangis, his thinking was quintessentially modern:

Go, look at the sahibs of England; Go learn from them their skills and ways; From their hands have sprung wonders and wonders; Go try and see if you can excel them.

Science education in British India was spread by three principal agents: British government, Christian missionaries, and education reformers from both Hindu and Muslim communities. Whereas the Hindus had many well-known reformers, among the Muslims the only well-known one was Sir Syed Ahmad Khan. His vigorous advocacy of science and modernity as a means of uplifting Indian Muslims differed sharply from those who feared learning English and science would diminish their religious faith. He had disagreed with Ghalib earlier, but, upon reflection, he became convinced that Indias Muslims must abandon conservatism and travel new paths.

Sir Syeds heroic efforts notwithstanding, Muslim enrolment in schools remained low. The University of Calcutta was the first secular Western-style university in India, and set standards as far away as Punjab. The requirements being rigorous by the standards of the time, only a few Muslims applied or qualified for admission. Although the populations in Bengal were proportional in size, hundreds of Hindus but just two Muslims passed the first BA examination in 1858.

Early years

Let us fast-forward to 1947. Of the 16 universities in British India, Pakistan inherited only one teaching university, i.e. the Punjab University in Lahore. Additionally, there were some 25-30 colleges in the areas that are now Pakistan. Most were in Punjab; Balochistan had none. Because Muslims had entered academia late and in fewer numbers, the senior faculty in almost all institutions of higher learning was predominantly Hindu at the time of partition. Once rioting began, they fled to India and Muslims from lower ranks filled their positions. Academic quality plummeted.

With time, education numbers slowly increased. By 1969 there were a total of eight universities in united Pakistan. The breakup and subsequent emergence of Bangladesh in 1971 temporarily froze further development. However, the quick post-partition promotions of junior faculty had profoundly debilitating consequences in terms of teaching quality. Mediocres rose to become department heads, deans, and vice-chancellors. They blocked bright young entrants lest their authority was challenged. As a result, rote learning became almost as common in universities and colleges as in schools and seminaries.

Nevertheless, in Pakistans early years, there were pockets of excellence in some S&T fields. I will mention only four.

Pakistans space programme began in 1961 with the launch of meteorological rockets provided by the United States. Initiated and headed by Professor Abdus Salam, the Space & Upper Atmosphere Research Commission (Suparco) grew rapidly in the 1960s and was more advanced than the Indian programme at the time.

Pakistans nuclear programme was set in place with the assistance of the US and, until 1972, had been directed towards nuclear power production and basic research. Personnel in the Pakistan Atomic Energy Commission (PAEC) were sent abroad in the 1960s for training. Canada provided Pakistans first nuclear reactor, the Karachi nuclear power plant (Kanupp). The returnees successfully maintained and operated the reactor even after the withdrawal of Canadian fuel and technical support. Indias 1974 nuclear test led to Pakistans open desire to match the Indian bomb, causing the reversal of the Wests nuclear assistance.

In industrial engineering, there was one outstanding institution, the Batala Engineering Company. Founded by entrepreneur C.M. Latif, Beco had relocated itself to Lahore from Batala (in what is now Indian Punjab) after partition. Beco produced a diverse range of heavy and light engineering products, such as diesel engines, machine tools and lathes. Like Indias Tata Industries, it was well set on the path of high growth, but was killed by the wave of nationalisation in 1972.

The creation of Islamabad University in 1967, and in particular the Institute of Physics associated with it, was the high point of academic research in Pakistan. Founded by Riazuddin, a student of Professor Salam, the institute maintained high-quality research in the frontier area of particle physics until its decline in the mid-1970s. At its peak, it compared favourably against a mid-quality physics department in the US.

Assessing the present

Globalisation means no country produces more than a fraction of what it needs and consumes. The more vibrant ones produce relatively more, have higher living standards for more citizens, are better organised, and have cleaner environments. Pakistan also has these aspirations, but is far more reliant on technologies developed elsewhere, such as automobiles, locomotives, aircraft, pharmaceuticals, computers, medical instrumentation, etc.

In principle, a small ecosystem could have developed around imported technologies, but there has been insufficient improvisation and innovation. For example, the once flourishing domestic electric fan industry has been pushed out by cleverer Chinese products. The small domestic output of finished products has led to a staggering trade imbalance that has compounded over time, leading to the current economic crisis.

I have attempted to compare Pakistans S&T in 2022 with other countries in the region based on performance in various domains of science, but the attempt admittedly is qualitative and subjective because a proper methodical study does not exist (Table 1).

Agri-sciences: These aim at raising yields of sugar, cotton, wheat, rice, and other crops by adapting and promoting standard techniques of pesticide use, plantation patterns, sowing methods, etc. As highly practical and relatively simple sciences, they are offshoots of the 1960s Green Revolution and are crucial for feeding Pakistans rapidly expanding population.

Nearly a dozen Pakistani institutions, such as National Institute for Biotechnology and Genetic Engineering (NIBGE), seem to have significantly improved local production and have reportedly developed better varieties of cotton, wheat, rice, tea and various fruits. Drip irrigation, food processing, and scientific livestock management are low-cost, but high-return investments.

Defence technology: Pakistan manufactures fission nuclear weapons and intermediate-range missiles. For both, the basic templates were provided by China, but local manufacturing capabilities had to be developed. The JF-17 fighter and Al-Khalid tank, produced with Chinese collaboration, are now force mainstays. In the 1980s, France provided three Agosta-90B submarines that were serviced locally. Over time a burgeoning Pakistani arms industry developed that now turns out a range of weapons from grenades to tanks, night vision devices to laser-guided weapons. However, the website of the Defence Export Promotion Organisation reveals little of what is being offered for sale. Pakistani arms exports have reportedly stalled in recent years. Poor quality control and lack of innovation are said to be responsible.

Space programme: Suparco has had six decades to mature, but as far as space exploration goes, it has practically folded up. The official website shows no future plans. Instead, it seems to have settled for routine testing of variants of missile series acquired from China. India, on the other hand, has clocked several major achievements, such as two successful orbiter missions to the Moon (2008) and one mission to Mars (2013). In 2017, India launched a record 100 satellites into orbit from the Indian Polar Space Launch Vehicle.

Civilian technology: Pakistans top 10 exports in 2021 were textiles, cotton, cereals, copper, fruits, minerals, sports goods, leather goods, software, and medical instruments. Only the last two items rely on S&T. As of 2020, the last year for which data is available, Pakistans hi-tech exports were 70 times lower than Indias and 2,523 times lower than Chinas (Table 2; the last entry is from the Mundi Index, which defines hi-tech exports as products with high research and development [R&D] intensity, such as in aerospace, computers, pharmaceuticals, scientific instruments and electrical machinery).

The above, however, understates the use of S&T in Pakistans domestic industrial production, which hinges critically upon imported machinery. This is used to produce textiles, Pakistans most important export, as well as cement, vegetable oil, fertiliser, sugar, steel, machinery, tobacco, paper, chemicals and food processing. Imported machinery has created an industrial ecosystem, but finished goods imported from China have adversely impacted many small industries.

Academic research: In developed countries, universities are the engines of scientific progress. Working in tandem with the industry, they help create new products and processes. On the other hand, in developing countries with small industrial bases, universities and colleges are primarily useful in creating a large pool of skilled people who can be gainfully employed in various sectors of the economy.

Irrespective of what area of science a student chooses, the key point that can make a graduate valuable is adaptability. A broad range of interests and knowledge and a good understanding of subject basics enables the students to be useful in different kinds of jobs.

Very few Pakistan institutions have done well at this. Hence, employers in the Middle East generally hire Pakistanis at lower levels relative to Indians, Iranians and Bangladeshis. Leaving aside the imported Cambridge system, rote-centred learning has discouraged students from logical thinking and stunted their cognitive capacities. The mathematical abilities of students and their teachers are generally poor. The only exceptions in the indigenous education system are exceptionally bright students at the right end of the Bell curve.

The poor quality of graduates emerging from Pakistani universities has caused employers to lose trust in grades and degrees. Many with PhDs are all but illiterate in their fields and unable to answer simple questions. At the same time, the number of publications produced by students has skyrocketed. Towards the end of studentship, many are credited with more papers than professors in the 1970s would have published over their lifetimes.

Professors and their students, encouraged by a disastrous policy by the Higher Education Commission (HEC) to reward publication numbers, have created a system where at least 90 per cent of so-called research papers are faulty, trivial or plagiarised. Whereas Chinese, Indian and Iranian speakers are invited to deliver lectures at top US campuses, Pakistans hyper-productive professors are nowhere to be seen there. Still, international university ranking organisations pick up numerical data and use their computers to create misleading rankings.

What not to do

The degradation in Pakistans scientific capabilities is alarming. Just how far Pakistan has fallen into the pit of ignorance and self-delusion was illustrated by a self-styled engineer trained in Khairpurs polytechnic institute who claimed to have invented a water kit that would extract energy from water. Never mind that this violated the rules of thermodynamics, and the rest of the world couldnt do it. He promised a new Pakistan with limitless energy, no need for petrol or gas, and no more loadshedding.

Politicians and media stars can perhaps be excused for being jubilant. But even our famed scientists fell for it and praised the water car publically. No practical joker could have demonstrated more dramatically the true state of science in Pakistan.

In this situation, one needs to carefully think about what to do, and, even more importantly, what not to do.

First, Pakistan does not need any more bricks and mortar for science; there is plenty of that around. A drive along Islamabads Constitution Avenue is lined with Pakistans most important buildings: Presidency, Prime Ministers House, Supreme Court, National Library, etc. On the other side of the road stand science buildings bearing names such as Pakistan Academy of Sciences, Pakistan Science Foundation, Islamic Academy of Sciences, Pakistan Council for Science and Technology, Committee on S&T of Organisation of Islamic Countries (Comstech), Commission on S&T for Sustainable Development in the South (Comsats) and others. A short distance from the Presidency is the head office of the PAEC, the largest single science-based institution in the country. About two miles away, on the campus of Quaid-i-Azam University is the National Centre for Physics (NCP).

Were any or all of these grand buildings to vanish suddenly into thin air, the world of science would simply shrug its shoulders. Shiny new cars parked in their driveways radiate opulence a tragic waste of resources. So-called science incubators in various cities have also proved ineffective. These were supposed to create new products for industry and business as well as new ideas for the world of academia. Nothing is visible. Do we need to spend more money doing this? Can we not understand that chickens may need incubators, but ideas hatch inside the head?

Second, we need to see through the numbers game that was started by the HEC in 2002, and immediately dispense with it. This game had deceived Pakistanis into believing that scientific research had increased when, in fact, the opposite happened.

More research papers and PhDs, and more universities and institutes do not at all translate into actual progress unless certain requirements are met. The most important of these are academic integrity and accurate assessment of scientific worth. As a result of incentivising corruption through cash rewards for papers and grants of PhD degrees, integrity has precipitously declined.

The way forward

The state of science in Pakistan, 75 years down the line, is visibly poor. There is little public understanding of science, our exports are largely low-tech textiles and raw materials, all significant weapons systems are imported, the space programme has almost ceased to exist, and scientific research carried out in universities and institutes carries little credibility or usefulness.

It is futile to blame a particular government; between one government and another, there has been little difference. The collective worldview, or weltanschauung, is at the core of the failure. This grim situation should energise us to drastically change our course. This must begin with changing the content and quality of education, beginning at the school level and then upward.

Instead of stuffing minds with propaganda, the goal must be to enhance cognitive capacity and creativity. How this can be done is well known: we can simply copy one of many successful countries. Attitudes acquired in school carry over to all higher levels colleges, universities, research institutes, and every other organisation. Good education encourages questioning and seeking answers. Traditional education, on the other hand, lulls the mind into passivity by endless memorisation and repetition.

As they say, to make an omelette, you must first break an egg. That egg, in Pakistans context, is the traditional value system that clashes with the value system of modernity and science. Pakistan hungers for the fruits of science, but a massive upsurge of zealotry has rendered it attitudinally unfit for nurturing science. Unlike its products, science cannot be acquired without accepting the fundamental premise of strict objectivity and, above all, the scientific method. Yes, it is as plain as that take it or leave it.

External Anatomy of Fishes

Anatomy is the study of an organisms structures. Fishes come in a diverse array of forms, many with special modifications. The shape, size, and structure of body parts permit different fishes to live in different environments or in different parts of the same environment. The external anatomy of a fish can reveal a great deal about where and how it lives.

When describing the basic anatomy of an organism, it is useful to have some common terms to help with orientation. Just as a map uses north, south, east, or west to help determine the location, orientation words are useful in describing anatomy. Table 4.3 defines common anatomy terms, Fig. 4.18 shows their orientation on three different animals.

Scientists measure and describe the external features of fishes to identify species, assess age and health, and learn about structure and function. Scientists work with a variety of types of fishes to do this. They might use a fresh fish, or they may use photographs, scientific drawings, or other kinds of detailed imageseven fish fossils.

One way to document details about a fish is gyotaku. Gyotaku (pronounced gee yo TAH koo) is a traditional Japanese method of printmaking, which uses the whole fish. This method can produce an accurate image of a fish (Fig. 4.19).

Gyotaku is a relatively new art form that developed in Japan, probably in the early- to mid-nineteenth century. Gyotaku means fish rubbing. Gyotaku is valued from both a scientific and artistic perspective. The detail captured in gyotaku, especially in historical prints, is an important source of information for scientists who want to know the size and external features of fish in the past. The color and artistic arrangement of gyotaku prints made by skilled artists also make them valuable pieces of art. The oldest known gyotaku print, made in 1862, is owned by the Homma Museum in Sakata, Japan.

Activity

Use your observation and investigation skills to investigate fish form and function by experimenting with ways of making gyotaku fish prints.

Perches are the most common type of bony fishes. As a result, people often use the words perch-like to describe a generic fish shape. (Fig. 4.21 A). Fusiform is the scientific term used to describe the perchs streamlined, torpedo shaped body. Compressiform means laterally flattened (Fig. 4.21 B). Depressiform means dorso-ventrally flattened (Fig. 4.21 C). Anguilliform means eel-like (Fig. 4.21 D). See Table 4.4 for additional descriptions of fish body shapes.

Table 4.4. Fish form and function: body shape

Images by Byron Inouye

The first anatomical structures many people identify on a fish are the fins. In fact, appendages, when present, as fins is part of one of the scientific definitions of a fish. Most fish have two kinds of fins: median and paired.

Median fins are single fins that run down the midline of the body. The dorsal fin is a median fin located on the dorsal side of the fish. The anal fin and caudal fin are also median fins. Paired fins are arranged in pairs, like human arms and legs. The pelvic and pectoral fins are both paired fins. (Table 4.5).

Table 4.5. Fish form and function: dorsal fin features

Images by Byron Inouye

Median Fins

Median fins, like the dorsal, anal, and caudal fins, can function like the keel of a boat and aid in stabilization (Fig. 4.22 A). Median fins can also serve other purposes, like protection in the lion fish (Fig. 4.22 B).

Caudal (Tail) Fin

The caudal fin is known commonly as the tail fin (Table 4.6). It is the primary appendage used for locomotion in many fishes. The caudal fin is also a median fin (Fig. 4.22 A).

The caudal peduncle is the base of the caudal fin. Peduncle means stem, and the caudal peduncle is where the strong swimming muscles of the tail are found. Together, the caudal fin acts like a propeller for the fish, and the caudal peduncle acts like a motor.

Table 4.6. Fish form and function: Caudal fin features

Images by Byron Inouye

Paired Fins

Fish have two sets of paired fins: pectoral and pelvic (Fig 4.25). The pectoral fins are vertical and are located on the sides of the fish, usually just past the operculum (Table 4.7). Pectoral fins are similar to human arms, which are found near the pectoral muscles. Many fish, such as reef fish like wrasses (Fig. 4.25 B), use their pectoral fins for locomotion.

Table 4.7. Fish form and function: Pectoral fin features

Images by Byron Inouye

The pelvic fins sit horizontally on the ventral side of the fish, past the pectoral fins (Table 4.8). Pelvic fins are similar to legs. Just like human legs, pelvic fins are associated with the pelvis of the fish.

Table 4.8. Fish form and function: Pelvic Fin Features

Unique and Specialized Fins

Paired fins are most commonly used for maneuvering, like the oars on a rowboat. However, both the pectoral and pelvic fins can also be highly specialized like those of the flying fish (Fig. 4.26 A). Unique combinations of other fins can also help fish to be even more specialized, like the pectoral and anal fins of a box fish (Fig. 4.26 B; see Table 4.9) .

Table 4.9. Fish form and function: Combinations of Fins

Scientists use fins to help identify and classify fish species. In more evolutionarily advanced fish, the fins are supported by bony structures: spines and soft rays. Spines are simple, unbranched, structures. Soft rays are compound, segmented, and branched structures (Fig. 4.27).

The mouth is at the front, or anterior end, of the fish. The mouth can reveal a lot about the fishs feeding habits (Table 4.10). The size, shape, and placement of the mouth, combined with the type of teeth, provide critical information about the feeding habits of a fish (Table 4.11).

For example, a fish with a mouth on the bottom of its head often feeds by digging in the bottom sediment (Fig. 4.28 A). A fish with a mouth oriented upward usually feeds in the water column, or even above the water (Fig. 4.28 B). When a fish has its mouth open, the front lip may slide down and out from the mouth. This sliding action of the mouth can help the fish create a vacuum and quickly suck in a big mouthful of water, which hopefully also includes prey!

Fig. 4.28. (A) A bottom facing mouth indicates bottom feeding preferences in the sturgeon. (B) An upward facing mouth shows the surface feeding adaptation of the arowana.

Table 4.10. Fish form and function: Mouth Features

Table 4.11. Fish form and function: Teeth Features

The eyes of fish resemble human eyes (Fig. 4.29). At the front of each eye is a lens, held in place by a suspensory ligament. The lens focuses images of objects on the retina. To bring near and far objects into focus, the lens retractor muscle moves the lens back and forth.

The retina is a light-sensitive membrane rich in nerves that connect to the optic lobes of the brain by optic nerves. When light shines on the nerves of the retina, the optic nerves send impulses to the optic lobes. Because fish have no eyelids, their eyes are always open.

Some elasmobranchs, and most teleost fishes, have color vision. Some fishes can also see in ultraviolet (UV) light. UV vision is especially useful for reef fishes. UV vision helps fishes in foraging, communication, and mate selection.

Elasmobranchs, and some teleosts, also have a tapetum lucidum. The tapetum lucidum is a shiny, reflective structure that reflects light and helps vision in low light situations. The tapetum lucidum is what makes the eyes of sharks and deep sea fish, as well as land mammals like cats and cows, shine at night.

Fish eyes are usually placed just dorsal of and above the mouth. Just like the mouth of a fish, the size, shape, and position of the eyes can provide information about where a fish lives and what it feeds on. For example, fish predators often have eyes facing forward in order to provide better depth perception. Prey fish, on the other hand, often have eyes on the sides of their bodies. This gives them a larger field of view for avoiding predators. (Table 4.12).

Table 4.12. Fish form and function: Eye Features

The sense of smell is well developed in some fishes. Water circulates through openings in the head called nostrils. Unlike humans, fish nostrils are not connected to any air passages. Fish nostrils serve no role in respiration. They are completely sensory.

The largest part of a fishs brain is the olfactory lobe, which is responsible for the sense of smell. Smell is the response to chemical molecules by nerve endings in the nostrils. Chemoreception is the scientific term for what nerve cells do to help an organism smell (see Table 4.13).

Taste ReceptorsTaste is another form of chemoreception. Fish can taste inside their mouth. Many fishes, like goatfish and catfish, also have fleshy structures called barbels around the chin, mouth, and nostrils (see Table 4.13 and Fig. 4.30). In some fishes, these barbels are used for touch and chemoreception.

Fig. 4.30.

Not all barbels have chemoreception. The barbels of some fish, like catfishes, are not equipped for chemical reception (Fig. 4.30 B). Some fish also have fleshy tabs called cirri on the head (Fig. 4.30 C). Cirri are not sensory organs.

Table 4.13. Fish form and function: Chemosensory Adaptation and Camouflage

Lateral lineMost fish have a structure called the lateral line that runs the length of the bodyfrom just behind the head to the caudal peduncle (Fig. 4.31). The lateral line is used to help fishes sense vibrations in the water. Vibrations can come from prey, predators, other fishes in a school, or environmental obstacles.

Fig. 4.31.

The lateral line is actually a row of small pits that contain special sensory hair cells (Fig. 4.32). These hair cells move in response to motion near the fish. The lateral line sense is useful in hunting prey, escaping predators, and schooling.

Fig. 4.32.

Ampullary receptors are sense organs made of jelly-filled pores that detect electricity. They can detect low frequency alternating current (AC) and direct current (DC). Ampullae detect electricity emitted by prey as well as the small electrical fields generated by a fishs own movement through the earths magnetic fields. Researchers think that this may help fishes use the Earths magnetic field for navigation. Fishes that have ampullae include sharks, sturgeon, lungfish, and elephant fish. The ampullae of sharks are known as Ampullae of Lorenzininamed for Stefano Lorenzini, who first described them in 1678(Fig. 4.33).

Stem Cell Therapy: Update and Clinical Research 2022

Posted: August 14, 2022 at 2:43 am

4. Stem Cell Therapy for Osteoarthritis

Osteoarthritis is a degenerative condition affecting the joints. Over time, the cartilage that protects joints, preventing the rubbing of one bone on another, breaks down. Eventually, this can lead to the deterioration of the underlying bone as well, causing aching, stiffness, and eventual immobility in many cases. The condition commonly affects the hips, knees, and thumbs, though it can also strike elbows, wrists, ankles, and fingers.

Stem cell procedure is offered in many clinics within and outside the United States and typically uses adipose cells as the stem cell source. Physicians extract these cells from fat tissue, separate out the stem cells from the rest, then prepare a solution containing growth factors and other ingredients necessary to tell stem cells how to develop in the new site. Once its prepared, doctors inject it into the affected site, such as a knee joint.

Regenexxis a U.S. company specializing in orthopedic applications of stem cells that was founded byDr. Chris Centeno. Dr. Centeno is an expert in the clinical use of mesenchymal stem cells (MSCs) within orthopedic applications. His Regenexx clinic in Denver, Colorado, draws patients from all over the U.S. who are seeking innovative, non-surgical treatments for osteoarthritis, as well as a wide range of other orthopedic applications.

As the visionary behind the revolutionaryRegenexx technology, he pioneered a procedure that involves extracting a small bone marrow sample through a needle and a blood draw from a vein in your arm. These samples are then processed in a laboratory and the stem cells it contains are injected into the area needing repair. The goal is to deliver large numbers of stem cells to the injured area.

Type I and Type II diabetes affect the body in different ways. Type I diabetes is genetic, and results from the pancreas failing to produce insulin, or producing too little of it. Insulin is what tells the body to remove glucose from the bloodstream and let it into cells, so they can use it for energy. Most likely this is due to an immune system disorder in which the body attacks its own islets, the pancreatic cells responsible for manufacturing insulin. In this case, stem cells may provide the same immune system-modulating effect as they do for other autoimmune diseases.

Type II diabetes is when the body becomes resistant to insulin. The pancreas may still make it, but the patients body does not sense it it is insulin resistant, which means the release of insulin in the bloodstream still does not result in cells taking up glucose. It remains in the bloodstream, causing dangerous hyperglycemia just as it does in the case of Type I.

The second condition may also respond to stem cell treatment, which can help moderate pancreatic productive of insulin as well as helping the body respond to it more effectively. Multiple clinical trials assessing the validity of stem cells for both diseases are underway, and many eagerly await their results.

There are many ongoing efforts to understand how stem cell therapy is able to help people with diabetes. One of the main centres is theCalifornia Institute of Regenerative Medicine, where you can view the areas ofresearch being conducted specifically to understand diabetes.

A review,published in the Progress in Stem Cell journal in 2019suggested a combination of antioxidants, growth factors or hormones along with MSCs (mesenchymal stem cells) in optimal combinations and concentrations for the treatment of diabetic nephropathy.

One of the most traumatic injuries to the human body is severing of the spinal cord. Depending on where the injury occurs, the patient may never walk or even move their arms again. For most of human history, such a traumatic injury was completely irreparable. In recent years, neurosurgery has given people back some of their function in cases like these, but outcomes are still all too often disappointing.

Stem cells provide serious hope for the future. Instead of trying to repair damaged nerves, stem cells offer the ability to replace them. By injecting stem cells to the site of the injury, the spinal column can repair itself, accessing all the ingredients it needs for the specialized job.

In combination with growth factors and hormones, stem cells are capable of traveling to the site of the injury assessing what needs rebuilding and stepping in to do the job for doctors. This limits the number of modifications needed from the outside and leaves the healing to the body.

While the mechanisms arent yet clear, it seems that hormones such as growth factors in addition to the location in the body can provide signposts to stem cells telling them what kinds of tissues are needed. Then the stem cells transform into them, integrate with the damaged tissue and repair it.

As of May 2022,more than 60 studieshave been launched to investigate the potential of stem cell therapy for spinal cord injuries under the U.S. Clinical Trial Registry.

These conditions all share the characteristic of the bodys immune system reacting to normal substances in the body as though they were pathogenic. That means instead of letting the body function normally, the immune system will attack tissues and substances, creating ongoing sickness and in many cases, eventually death.

Stem cell therapy has two possible benefits in the case of autoimmune diseases. For one thing, it can help repair and regenerative tissues damaged in an autoimmune attack. Stem cells can help them repair nerves, skin, blood, organs, and more. This helps the patient regain their health and fight the degenerative nature of such diseases.

Second, stem cells can actually modulate the immune system so that it no longer attacks the body so viciously or at all. Research demonstrates thatstem cells can minimize the pathological effects of the immune system, making it so the body no longer attacks itself all while preserving its ability to attack foreign substances and real pathogens.

As is the case with most of these therapies, the biggest benefit of stem cell treatment for heart disease is its ability to replace damaged or dead cells without the need for invasive surgery or transplants. An injection of stem cells can give the body the ingredients it needs to grow the specialized cells on site, ideally without having to put the patient under or open them up. The exact mechanisms of this procedure are not as yet clear, however.

On 16 May, 2018,Nature Newsreported that Japans health ministry gave doctors at Osaka University permission to take sheets of tissue derived from stem cells and use them to treat diseased human hearts. From preclinical studies in pigs, it appears that thin sheets of cell grafts grown frominduced pluripotent stem cellscan improve heart function. While the treatment approved by Japans health ministry will only be tested in three patients, a follow-up trial could enroll ten or more patients.

There are more than 1,500 scientific publications published related to "stem cell" and "spinal cord injury" on theNational Library of Medicine.As of May 2022,more than 200 studieshave been launched to investigate the potential of stem cell therapy for spinal cord injuries under the U.S. Clinical Trial Registry.

Journal of Gerontology - The results of 2 clinical studies, published in The Journals of Gerontology, showed how a type of adult stem cell called mesenchymal stem cells (MSCs) could reverse the effects of aging.

Hormone Replacement Therapy for Men: What to Know – Healthline

Posted: August 14, 2022 at 2:41 am

Overview

Hormone replacement therapy is a bit of a misnomer. Its natural for mens testosterone levels to decrease as they get older. So, hormone therapy doesnt replace anything that is naturally missing.

Testosterone is required for:

However, the natural decrease of this hormone in men typically doesnt affect overall health any more than the aging process does. Medical experts disagree about the significance of a testosterone level decrease. They also disagree about the health benefits of hormone therapy use to combat the natural aging process in men, especially given the risks.

Learn more: Is low testosterone dangerous to your health?

Some men with unnaturally low levels of testosterone can benefit from hormone therapy. For example, the condition hypogonadism can cause unnaturally low levels of testosterone. Its a dysfunction of the testicles that prevents the body from producing the right amount of testosterone.

Whats less certain is whether testosterone therapy can benefit healthy men whose testosterone decline is simply caused by aging. This has been a difficult question for researchers to answer. Not many studies have observed the effects of testosterone therapy in men with healthy levels of the hormone. The studies that have were smaller and had unclear results.

Read more: Testosterone levels by age

If your doctor suggests testosterone therapy, several options are available. These include:

Side effects are a primary drawback of hormone therapy with testosterone. While some of the side effects are relatively minor, others are more serious.

Minor potential side effects of hormone therapy with testosterone include:

More severe potential side effects include:

An increased number of red blood cells can cause:

Hormone therapy can be a helpful treatment for men with unnaturally low levels of testosterone. However, it doesnt come without risks. These risks may outweigh the benefits if youre considering hormone therapy to make up for a natural decrease in testosterone levels.

Talk with your doctor about safer alternatives. Resistance exercise can help you build muscle mass, and walking, running, and swimming can help keep your heart strong.

Cycling and HRT: How will it affect me? – Cyclist

Posted: August 14, 2022 at 2:41 am

Hormones are chemical messages sent around the body that stimulate physiological change, bringing improved states of function and balance. Insulin, for example, is released after a meal and tells receptor cells around the body to absorb glucose in readiness for future energy demands. Unfortunately, our hormonal efficacy tends to deteriorate as we age.

Insulin is just one of many hormones that comprise our endocrine system, which is responsible for the hormones that control metabolism, growth, organs, mood and reproduction but we also have dominant sex hormones that drive our development, function and daily lived experience.

Testosterone is a key sex steroid for males (although it also circulates in females at lower levels) used to calibrate functions including libido, muscle mass, bone density and fat storage.

As you may have guessed, testosterone declines slowly past the age of 30 such that a normal level for under-50 males is 8.7-29nmol/L (female 0.2-1.7nmol/L), while the over-50 male range drops to 6-26nmol/L.

This is a very gradual drop that can, to a point, be offset with strength training, nutrition, and lifestyle adaptations, says endocrinologist Dr Nicky Keay. The hormone drop in males is linear, while for many females, especially masters athletes, the opposite is true.

The principal female hormones are oestrogen and progesterone. The former has positive ramifications for heart and bone health as well as brain function and general mood. The latters primary role is to balance oestrogen levels to ensure the ongoing health of the uterus.

The menopause is the point in time when female ovaries stop producing hormones and eggs. But this is not an on/off switch. Perimenopause is the transition to retirement of the ovaries, says Dr Keay. Sometimes you feel OK and sometimes you dont.

Symptoms of perimenopause include hot flushes, poor sleep, fatigue, feeling happy or sad for no reason, muscle and joint aches. For masters athletes the list of symptoms adds even more stress, precisely because female hormones are so critical for the maintenanceof consistent intense training and performance.

Until relatively recently, women had to accept it, but hormone replacement therapy, HRT, has changed that. As Dr Keay says, Why should females feel like this for the rest of their lives? We could potentially spend between one third to a half of our lives feeling like this.

HRT is a prescribed combination of progesterone and oestrogen. Dr Keay cites several key issues to consider for athletes contemplating HRT.

First off, its better to start HRT early to get the best long-term effects. The most effective HRT chemicals have the same molecular structure as your body produces and should be taken through the skin as a gel or patch, and thedose will require personalising.

So what will a female athlete feel when they start on HRT? Dr Keay predicts they should feel better recovery, focus and drive, but also cautions that female masters athletes, even on HRT, should plan to be kinder to themselves, as well as scheduling more time for recovery and strength training to offset both bone-minerality and muscle-bulk loss.

Jenny Copnall, five-time national mountain-bike champion turned cycling coach, says, As a coach Id approach menopause in much the same way as I do working with any rider, and that is through good communication, great attention to recovery and recovery indicators, and working with the individual to tailor a plan to suit their needs and lifestyle. Just like menstrual cycles, its a pretty individual thing.

The controversy over HRT has now largely been dispelled by recent research, so what about testosterone replacement therapy (TRT) as males advance in age and lose hair, muscle mass and vitality? TRT and HRT are not actually compatible propositions, because testosterone and oestrogen decline at very different rates.

Females lose 90% of their hormones over a very short time-span. Post-30 males, on the other hand, have a constant and shallow decline in testosterone production, around 1-2% per year.

TRT carries health risks such as liver damage, cardiac problems and increased incidence of prostate cancer, while health and performance advantages are at best questionable.

Instead, male masters athletes can modify their lifestyle, training and diet. For many female masters athletes, however, HRT is potentially an incredibly effective tool to keep performing at a high level.

6 LGBTQ2S+ musicians celebrate the artists who came before them – CBC.ca

Posted: August 14, 2022 at 2:40 am

Pride spans from June to August across Canada, depending on where you live, giving us a vibrant and wide-ranging landscape to celebratea movement thatisrooted in protest against police brutality, and whichwas originally led byqueer people of colour,includingMarsha P. Johnson.

To recognize those who came before, CBC Music asked Canadian LGBTQ2S+ musicians who has made a difference to them as artists, and why and what song they think is a must-hear from the artist they're celebrating. The result is a beautiful recognition of both industry veterans and contemporaries plus a perfect little playlist to mark the last month of Pride for 2022.

Artist: PartnerArtist to celebrate: Tegan and Sara

"We each found out about Tegan and Sara when we were in our teens. Like many, many, many other queer people of our age, something about the music and the look and the stories they told onstage spoke to us on a deep level. They made being gay seem exciting and cool but also relatable. Everything about them was aspirational. They had the coolest haircuts, used interesting chords, and seemed hilarious and wise.

"As a child, there were definitely musicians around who I knew to be queer, like Elton John and k.d. lang. They were very cool and glamorous but seemed to exist in a faraway different world. The thing that seemed exciting about Tegan and Sara was that they bridged that gap. Elton John lived in a castle, but Tegan and Sara seemed to live in an extremely exciting version of my own world, and they gave my friends and I a roadmap to a future we could be excited about."

Must-hear song: "Yellow"

"I love their entire back catalogue, but they also just put out a brand new single called "Yellow" so everyone should listen to that."

Artist: iskwArtist to celebrate: Ria Mae

"I've been a fan of Ria's for many, many years, and as luck would have it we were a part of some Juno programming together in 2018, which is when we met. Not only did we become friends from this, but Ria became an absolute shoulder I have leaned on manytimes while navigating this music industry, and all the many challenges and frustrations that come with representing ourselves honestly and with conviction. So not only was I able to befriend someone who I admired creatively, but I was able to lean on and learn from another strong creative in the biz."

Must-hear song: "Broken" featuring Tegan Quin

"This is just a really, really good song! I love the groove, I love singing along, the vocal harmonies and melodies, plus I love hearing both Ria and Tegan on the same tune!"

Artist: Mariel BuckleyArtist to celebrate: k.d. lang

"For obvious reasons, I had to choose k.d. lang, an absolutely unparalleled talent that defied gender and sexuality. Early in my career, when I was still woodshedding covers and working slowly on my original tunes, I played a ton of traditional country during happy-hour slots. I had a bassist who steered me toward[lang's 1989 album] Absolute Torch and Twang and it totally blew me away. I didn't really understand the importance of visibility, at the time. The early 2000s were not as evolved, and I assumed that gay folks were supposed to exist privately because that's what I mostly perceived. Thankfully, I've also lived through a lot of progress for acceptance and that's been awesome to see. I'm thankful to see steps forward every day, and I hope for more inclusion from artists to labels. The more representation we can secure, the safer and happier our next generations can be."

Must-hear song: "Western Stars"

"A lang song that I think people should hear is "Western Stars." It kicks off Shadowland, an incredible, deep and thoughtful work of country noir. The song is a masterclass in balanced production and vocal emotion."

Artist: Adria KainArtist to celebrate: Frank Ocean

"Growing up, I wasn't fully aware of my sexuality or that of others. I feel like it wasn't even as prevalent in music as it is now, so for me it didn't really leave an impact until I was much older and already a fully developed artist. The only artist who ever changed my perspective on things and really inspired me to take things with music to another level was Frank Ocean.

"Frank reminded me of my purpose outside of anything, and how that was and is always the most important thing over anything else so when I write, I write solely from that space. He reminded me that sometimes when you can't speak the words of what you're feeling, finding the melodies that compliment the amount of emotion can be another language. I'm naturally a very emotional person and before hearing Frank I didn't necessarily know how to truly express myself without giving away too much or being overly dramatic, so it was nice to stumble across an artist like him who I felt spoke the same language as me musically, and really just all around."

Must-hear song: "Dust"

"It's always so hard to just pick one Frank Ocean song, but one of my favourites is "Dust" from his very first project,Nostalgia Ultra. This song, to me, is so beautifully written. It's the first song that challenged me to write from a metaphoric place. To use the concept of a library and the reading of books to describe meeting someone new and thinking about the past things that you've both done and experienced, while learning to let go and try love regardless of fear and overthinking a masterpiece."

Artist: T. ThomasonArtist to celebrate: Lucas Silveira

"Lucas is often most recognized as the first openly trans man to be signed to a major label, and the frontman of his band the Cliks. That's how I became aware of him in high school, and when I opened for the Cliks in Toronto almost 10years ago it was a serious dream come true. We didn't stay in touch beyond following each other on social media, but a couple years after that show, I reached out to Lucas and he agreed to meet me at a little cafin west end Toronto. That was the beginning of an ongoing mentorship and friendship.

"Lucas has been so generous with his time, experienceand knowledge of the music industry over the years. When I decided I needed to transition with testosterone hormone replacement therapy [THRT], I was terrified I'd have to give up my singing career. Lucas reassured me this wasn't true, and shared his approach to THRT and continuing to sing. He connected me with my vocal coach, Ali Garrison, who I still work with. I would not have the career I do, or be the person I am today if, in 2015, Lucas had not been willing to meet up with a random kid he'd met once. I want to celebrate not only Lucas's fantastic talent and artistry, but his tenacity, graceand kindness as a trailblazer in this incredibly challenging industry."

Must-hear song: "Dream Lover"

"This song proves that transitioning with THRT and continuing to sing is absolutely possible. Lucas's vocal range is incredible and this song showcases it in such an impressive way. The way he blends from chest voice to such a strong and dynamic falsetto is stunning to listen to. Lucas then revisits the range in his blended register. It's amazing to hear the power and control he has. It's a stunning vocal performance that displays admirable (OK, enviable) technique even if you don't know about Lucas's journey to this current voice. It's a joy to listen to because it sounds like so much fun to sing. Listening to Lucas's voice brings home a very powerful truth about transness to me trans people defy what we are told is possible, we reject limitations presented to us as absolutes simply by finding and being ourselves. We create our own glorious realities and bring beauty to the world that is brand new and unique to each of us."

Artist: Shawnee KishArtist to celebrate: Melissa Etheridge

"I looked up to Melissa Etheridge ever since I can remember. I was five years old in the back of my mom's car on a road trip hearing the soul of Melissa's voice showcased through her stories of living in a world of love, life and heartbreak. Not fully knowing just how influential an artist like her was, even to me at that time, I look back and feel lucky to have known her music in such depth as a kid. She's out, proud, epically talented with a big voice and a career I admire so much now as an adult and musician.

"She is true music, true artistry and I hope one day to be able to look back at my own journey and to have created a long-lasting, meaningful career the same way she has. Her legacy to me is someone who paved the way as an out artist and woman making no apologies for herself or who she loves, and showcasing that through her music. I can assure you that would have come with its challenges challenges I have also faced in music at times. She was someone for people like me to look up to at a time when I needed it most, to know I wasn't alone out here."

Must-hear song: "Bring me Some Water"

"'Bring Me Some Water'is so clever. I love the writing, the passion and voice behind this track. It's a forever song with a sea of people singing back to Melissa in a live setting."

Diagnostic Robotics has AI catching health problems before they take you to the ER – TechCrunch

Posted: August 14, 2022 at 2:38 am

A stitch in time saves nine, they say and a blood thinner in time saves a trip to the emergency room for a heart attack, as Diagnostic Robotics hopes to show. The companys machine learning-powered preventative care aims to predict and avoid dangerous (and costly) medical crises, saving everyone money and hopefully keeping them healthier in general and it has raised $45 million to scale up.

Its important to explain at the start that this particular combination of AI, insurance, hospital bills and predictive medicine isnt some kind of technotopian nightmare. The whole company is based on the fact that its both better for you and cheaper if you, for example, improve your heart health rather than have a heart attack.

Thats why your doctors tell you to cut down on red meat and maybe even take a cholesterol-maintenance medication instead of saying well, if you have a heart attack just go to the ER. Its just common sense, and it also saves patients, hospitals and insurance companies money. And dont worry, this kind of prediction cant be used to raise your premiums or deny care. They want you making monthly payments they just dont want to have to shell out for a $25,000 operation if they can help it.

The question is, what about less obvious conditions, or ones that patients havent had specific tests for? This is where machine learning models come in; theyre very good at teasing out a signal from a large amount of noise. And in this case the AI was trained on 65 million anonymized medical records.

We see how people look before the problems everything we do is preventative care, said Kira Radinsky, CEO and co-founder of Diagnostic Robotics. Its all about offering the right intervention, at the right time, to the right patient.

She noted that providers often focus on the most expensive patients in order to reduce costs for example, someone with advanced heart disease. But while acute and maintenance care continues to be important for them, that money has already gone out the door. On the other hand, if you diagnose someone with early signs of congestive heart failure, you can stop it from advancing and save money and possibly even a life. And the technique applies beyond things that can be detected in labs.

Say the challenge is to find patients suffering from depression or anxiety, but arent taking any medications, Radinsky proposed. How do you identify someone with depression or anxiety based on medical records? We identify the entropy of their visits lots of providers, lots of complaints thats a strong signal. Then you do specific questions, a medical triage, and you get them connected to a psychologist or psychiatrist, and theyre no longer deteriorating.

The company claims it can reduce ER visits by three quarters, which is important beyond the immediate benefits for a person and their provider; ERs and urgent cares are overwhelmed in the U.S., paradoxically due to the pervasive fear of incurring huge medical expenses.

In many cases, she said, medical providers or insurers will offer medications or treatment for free or at nominal cost, because they know theyre saving themselves a bigger bill down the line. Sure, its all out of self-interest, but that means you can trust them.

The Tel Aviv-based Diagnostic Robotics just raised a $45 million B round, led by StageOne investors, with participation from Mayo Clinic, Technion (Israel Institute of Technology) and Bradley Bloom. Radinsky said this will help the company start working more directly with providers, taking on more holistic health goals in addition to specific high-risk conditions. (The company currently tracks around 20.)

A pilot test of this broader approach was recently validated in a study of a few hundred patients, in which the AI-prepared health plan was statistically indistinguishable from a clinicians. The company is already serving millions of patients in some capacity, in Israel, South Africa and the U.S., with Blue Cross Rhode Island.

If they expand to your provider, dont expect some kind of robotic examination, though the name obviously suggests this.

Youll get phone calls from care managers offering additional treatments, for free or almost for free, Radinsky said. The AI will already have done its work, and maybe your test results and location suggest youre at risk for something and youd do well to take these recommendations seriously. AI may have a lot of room to grow still but its good at sniffing out statistical correlations.

She was careful to add that they are also actively working on finding, defining and mitigating bias in the algorithms, whether it results from biased data or human error somewhere else along the lines. What the algorithm is trying to do is see who will benefit the most, Radinsky explained, but as with other forms of AI and machine learning, only careful monitoring will tell whether its idea of who benefits matches the real world.
