Hunters, Hearing Loss, and New Tech to Fix it – MeatEater
Posted: June 13, 2022 at 2:29 am
If ever there was an epidemic in the hunting community, itd be hearing loss. When target practice is a way of life, its easy to become blas about earmuffs. When that buck is about to get over the ridge, jamming in ear plugs is the last of our worries. For those reasons, most of us will go through the rest of our lives unable to hear pheasants cackle and elk bugle as well as we should.
It doesnt have to be that way. You can take steps now to stem the loss of auditory ability with simple, cheap solutions or technologically advanced ones.
Dr. Grace Sturdivant is an evangelist for saving hunters eardrums. Starting her career as a Vanderbilt-trained Doctor of Audiology, she spent years researching, diagnosing, and treating hearing loss. Eventually, however, she decided to take a more proactive approach.
I've shifted from the traditional academic medical setting practice, Sturdivant told MeatEater. I want to prevent and delay the problems that I spent so many years treating in people who were debilitated by this problem that was largely preventable. And they acquired this problem by doing these worthwhile things that they love.
Raised in a Mississippian hunting family, she wasnt about to tell shooters to stop shooting: I want you to continue doing what you're doing. I just want to give you some tools to do it safer.
That desire led to the founding of her company, OtoPro Technologies. Through this business, Sturdivant advocates for ear protection while serving as a consultant for shooters, musicians, pilots, builders, machine operators, and others who deal in loud noises for work or pleasure.
I love music. I don't want tell people Don't go stand front and center at your favorite show. Go do it. But let me give you some really cool specially filtered, small, tiny earplugs so you can take the edge off and your ears won't be ringing all night, she said. That's the whole mission. Even if it comes down to me just educating you on how to wear the foam ear plugs correctly, thats cool.
How Do Guns Affect Hearing?
Sturdivant cites a University of Wisconsin study that found men aged 48 to 92 who hunted regularly were more likely to experience high-frequency hearing loss, a risk that increased 7% for every five years a man had been hunting. Of the participants surveyed, 38% of recreational shooters and 95% said they never wore hearing protection while shooting in the last year.
Another more recent study found that the usage of hearing protection while shooting has increased in recent years, but auditory loss is still a big problem. Still, there are plenty of factors to consider in order to mitigate.
High-intensity impulse sounds will permanently damage delicate cochlear structures, and thus individuals who shoot firearms are at a higher risk of bilateral, high-frequency, noise-induced hearing loss (NIHL) than peer groups who do not shoot, the studys authors wrote. In this article, we describe several factors that influence the risk of NIHL, including the use of a muzzle brake, the number of shots fired, the distance between shooters, the shooting environment, the choice of ammunition, the use of a suppressor, and hearing protection fit and use.
But whats really happening when we pull the trigger that makes our ears hurt and function poorly as a result?
When you think about decibels, think about them in terms of sound pressure level, which is exactly what a decibel is, Sturdivant said. And with a gunshot you're typically at around 150 decibels sound pressure level. And when that amount of sound pressure hits your hearing nerve, it's hitting those hair fibers that are just these tiny, delicate hair fibers that send the sound to the brain. It's hitting them really hard and really fast, like an impulse impact. And so the amount that those hair cells are able to withstand instantly from a 150 decibel sound pressure level is not very much. So, oftentimes, you'll see instant damage or at least instant weakening at that level.
In contrast, she said, you could withstand a lower decibel level for much longer. But even an 80-decibel noise for a long duration will weaken those microscopic hair fibers in your ears. Those organs can recover and regenerate, but you need to allow them time to do so after exposure to loud noises. If you let the problem go on long enough, however, you may be faced with even worse issues.
Of course, not only the communication difficulties and just the frustration of not being able to hear; there's really more to it than that, Sturdivant said. And a large reason why I started this business was because of all the connections that we see in the area of cognitive decline and dementia with hearing loss. Because we actually hear with our brains and when those hair cells are able to send the signal in a healthy way to the brain to be processed, it's stimulating some very specific areas of the brain. And when those areas are not stimulated, we see an earlier onset and a faster rate of cognitive decline with various forms of dementia.
Sturdivant said that most people wait seven to 10 years to do anything about their hearing loss. That can allow cognitive decline to take hold sooner than it would otherwise. Like with most medicine, an ounce of prevention is worth a pound of cure.
How to Protect Your Ears While Shooting
Hearing protection technology has advanced rapidly in recent years, especially from military contractors and European firms. While there are many great offerings in the consumer hunting market already, theres a lot more ultra-modern tech you probably havent even heard about yet. Sturdivant stays highly up to date on all the bleeding-edge ear care gadgets available worldwide.
One of the biggest developments recently becoming widely available to consumers is simple and affordable custom fittings.
Custom is very important because we want a tight air seal of your ear, she said. If there's any air leakage, sound waves are passing through.
Its also a major boon if, say, you got punched in the head in high school or otherwise damaged your ear canals in sports or accidentsplacing you among the minority in regard to one-size-fits-most ear plugs.
Some new offerings also allow air passage to help defeat that pressurized-airplane-cabin, stuffed-up feeling you get from air-tight ear plugs.
There's lots of passive filters for hunting and shooting. This is awesome because it allows the most in and it allows some air exchange. When you first wear it, you wonder like, is this really fitting my ear? Because I can feel air, which is strange. But that's the whole point, Sturdivant said. Theres a sound pressure membrane that vibrates to let the sound pass through and then it stiffens up at 95-decibel sound pressure level. So, it's an all-or-nothing filter.
For hunters who may have already beat the hell out of their eardrums, a favorite feature is ambient microphones built into the earplugs that amplify the surrounding noise, making you still able (or even more able) to hear a buck snort or goose wings whoosh. At the gun range, that means you dont need to take off your headphones and yank out your ear plugs between each target session in order to register what your friends are hollering at you. Ambient noise will sound practically normal, but the plugs immediately block out the concussion of a gun blast.
Some of the higher-end models offer Bluetooth streaming capability, so you can play your favorite podcast while plinking at targets or running the circular saw. Some of these also offer wind noise reduction features, or the ability to adjust the volume level for both ears individually. There are solutions for every situation and budget, from OtoPros new proprietary, universal passive filter ear plugs to $300 custom rigs.
Or course, none of this is meant to say that you cant protect your ears well with items you likely already own (or could acquire painlessly). Sturdivant says that the cheap foam ear plugs still make a big difference, so long as theyre inserted correctly. Pinch and roll the tip up tightly then push it in far enough that none of the material is extending outside your ears, creating an air-tight seal against sound. Pair that with an affordable pair of Caldwell earmuffs and youre a long ways toward saving your ears for later in life.
Sturdivant said that she is seeing a tide change in the way hunters view protecting themselves and others. Folks over 60 tend to think the damage is done, she said, but younger generationsthose that grew up with mandatory seatbelt laws, for exampleare beginning to be more proactive and invest in preventative measures. That may be the most true for parents introducing their kids to hunting and shooting. If you start young enough with good ear protection, theres no reason why a person should ever lose their auditory abilities. Sturdivant hopes to keep that trend growing and encourages every hunter and shooter to share the same message with their family and friends.
My job is to motivate you, to protect your hearing. Your job is to become damned and determined to be like, I'm going to get over this hump and this is going to become my new normal. And then it becomes second nature, she concluded. Hearing protection just needs to be another piece of essential hunter safety gear.

UB-led study presents critical step forward in understanding Parkinson’s disease and how to treat it – University at Buffalo
Posted: June 13, 2022 at 2:27 am
BUFFALO, N.Y. A new study led by a researcher in the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo has important implications for developing future treatments for Parkinsons disease (PD), a progressive nervous system disorder that affects movement and often includes tremors.
In this study, we find a method to differentiate human induced pluripotent stem cells (iPSCs) to A9 dopamine neurons (A9 DA), which are lost in Parkinsons disease, says Jian Feng, PhD, professor of physiology and biophysics in the Jacobs School and the senior author on the paper published May 24 in Molecular Psychiatry.
These neurons are pacemakers that continuously fire action potentials regardless of excitatory inputs from other neurons, he adds. Their pacemaking property is very important to their function and underlies their vulnerability in Parkinsons disease.
This exciting breakthrough is a critical step forward in efforts to better understand Parkinsons disease and how to treat it, says Allison Brashear, MD, UBs vice president for health sciences and dean of the Jacobs School. Jian Feng and his team are to be commended for their innovation and resolve.
Feng explains there are many different types of dopamine neurons in the human brain, and each type is responsible for different brain functions.
Nigral dopamine neurons, also known as the A9 DA neurons, are responsible for controlling voluntary movements. The loss of these neurons causes the movement symptoms of Parkinsons disease, he says.
Scientists have been trying hard to generate these neurons from human pluripotent stem cells to study Parkinsons disease and develop better therapies, Feng says. We have succeeded in making A9 dopamine neurons from human induced pluripotent stem cells. It means that we can now generate these neurons from any PD patients to study their disease.
Feng notes that A9 DA neurons are probably the largest cells in the human body. Their volume is about four times the volume of a mature human egg.
Over 99 percent of the volume is contributed by their extremely extensive axon branches. The total length of axon branches of a single A9 DA neuron is about 4.5 meters, he says. The cell is like the water supply system in a city, with a relatively small plant and hundreds of miles of water pipes going to each building.
In addition to their unique morphology, the A9 DA neurons are pacemakers they fire action potentials continuously regardless of synaptic input.
They depend on Ca2+ channels to maintain the pacemaking activities. Thus, the cells need to deal with a lot of stress from handling Ca2+ and dopamine, Feng says. These unique features of A9 DA neurons make them vulnerable. Lots of efforts are being directed at understanding these vulnerabilities, with the hope of finding a way to arrest or prevent their loss in Parkinsons disease.
Pacemaking is an important feature and vulnerability of A9 DA neurons. Now that we can generate A9 DA pacemakers from any patient, it is possible to use these neurons to screen for compounds that may protect their loss in PD, Feng notes. It is also possible to test whether these cells are a better candidate for transplantation therapy of PD.
To differentiate human iPSCs to A9 DA neurons, the researchers tried to mimic what happens in embryonic development, in which the cells secrete proteins called morphogens to signal to each other their correct position and destiny in the embryo.
Feng notes the A9 DA neurons are in the ventral part of the midbrain in development.
Thus, we differentiate the human iPSCs in three stages, each with different chemicals to mimic the developmental process, he says. The challenge is to identify the correct concentration, duration, and treatment window of each chemical.
The combination of this painstaking work, which is based on previous work by many others in the field, makes it possible for us to generate A9 DA neurons, Feng adds.
Feng points out there are a number of roadblocks to studying Parkinsons disease, but that significant progress is being made.
There is no objective diagnostic test of Parkinsons disease, and when PD is diagnosed by clinical symptoms, it is already too late. The loss of nigral DA neurons has already been going on for at least a decade, he says.
There was previously no way to make human dopamine neurons from a PD patient so we could study these neurons to find out what goes wrong.
Scientists have been using animal models and human cell lines to study Parkinsons disease, but these systems are inadequate in their ability to reflect the situation in human nigral DA neurons, Feng says.
Just within the past 15 years, PD research has been transformed by the ability to make patient-specific dopamine neurons that are increasingly similar to their counterparts in the brain of a PD patient.
Houbo Jiang, PhD, research scientist in the Department of Physiology and Biophysics, and Hong Li, PhD, a former postdoctoral associate in the Department of Physiology and Biophysics, are co first-authors on the paper.
Other co-authors on the study are: Hanqin Li, PhD, a graduate of the doctoral program in neuroscience and currently a postdoctoral fellow at University of California, Berkeley; Li Li, a trainee in UBs doctoral program in neuroscience; and Zhen Yan, PhD, SUNY Distinguished Professor of physiology and biophysics.
The study was funded by the Department of Veterans Affairs, National Institutes of Health and by New York State Stem Cell Science (NYSTEM).

Dr. Andrew Weil Receives Integrative Healthcare Leader Award – University of Arizona
Posted: June 13, 2022 at 2:26 am
A world-renowned author and expert in the field of integrative medicine, Andrew T. Weil, MD, founder and director of the Andrew Weil Center for Integrative Medicine at the University of Arizona College of Medicine Tucson, was recognized recently with the top award given by the Integrative Healthcare Symposium.
Im honored to receive the symposiums 2022 Leadership Award, Dr. Weil said. Integrative health care is the way of the future, and the University of Arizona Health Sciences is leading that way. Our Center for Integrative Medicine sets the standard for training physicians, nurses, and allied health professionals to provide this kind of care in order to improve health outcomes and lower health care costs.
The annual award was presented to Dr. Weil, who also gave the symposiums keynote address on The Evolution of Integrative Medicine, earlier this year in New York City.
Presenting the award to Dr. Weil was Aly Cohen, MD, a 2014 graduate of the centers Fellowship in Integrative Medicine, founder of Integrative Rheumatology Associates and The Smart Human LLC, and co-author of the book, Non-Toxic: Guide to Living Healthy in a Chemical World. Dr. Cohen is the guest on the latest Body of Wonder podcast with Dr. Weil and center executive director Victoria Maizes, MD.
In lauding Dr. Weil, Dr. Cohen told the tale of how his car broke down in Tucson in the 1970s while he was traveling across country, he fell in love with the desert and stayed. Well, lucky for us. Combining the number of patients reached through fellowship graduates, health coaches, residents in training, medical students and researchers, some 8 million patients are guided by your teachings and are quite grateful your car broke down in Tucson many moons ago, she said.
Commenting on his 15 books, Dr. Cohen said, In an era of plentiful, often radical guidebooks and scary health news flashes, he has provided an oasis for balance and common sense for readers. Dr. Weil, your long and brave history of challenging the status quo of Western medicine and your ongoing mission to educate others through print, social media, television and lectures is a testament to the beautiful and rich journey youve taken.
After graduating high school in Philadelphia in 1959, Dr. Weil won an American Association for the United Nations scholarship that allowed him to travel abroad for a year where he lived with families in India, Thailand and Greece. Upon his return, he did his undergraduate studies in biology and ethnobotany at Harvard University and earned his medical degree from Harvard in 1968.
He interned at Mount Zion Hospital in San Francisco, then took a post with the National Institute of Mental Health before writing his first book, The Natural Mind. As a fellow of the Institute of Current World Affairs from 1971-75, Dr. Weil traveled widely in the Americas and Africa, studying medicinal plants and alternative treatment methods for disease. From 1971-84, he also was on the research staff of the Harvard Botanical Museum and conducted investigations of medicinal and psychoactive plants.
Dr. Weil founded the Program in Integrative Medicine in 1994 at the UArizona College of Medicine Tucson. Fourteen years later, the program by then a division in the colleges Department of Medicine was designated a center of excellence by the Arizona Board of Regents. In 2019, the center was renamed as the Andrew Weil Center for Integrative Medicine. The center broke ground on its new $23 million, donor-funded building March 16.
A UArizona clinical professor of medicine and public health and the Lovell-Jones Endowed Chair in Integrative Medicine, Dr. Weil also is editorial director of DrWeil.com, a leading online resource for healthy living based on a philosophy of integrative medicine, and a founder and partner of True Food Kitchen restaurants, whose recipes are the basis for his New York Times best-selling book, True Food.

Should You Avoid Nightshades? A Look at the Research – Forks Over Knives
Posted: June 13, 2022 at 2:26 am
While the name might seem ominous and call to mind the contents of a sorcerers cauldron, nightshades are among the most common fruits and vegetables, and you likely already have some in your kitchen. So, what are nightshades, and are they good for you?
There are 2,500 species of flowering plants known as nightshades within the Solanaceae plant family.
The Summer 2022Magazine Is Here!
Our gorgeous bookazine features expert tips, inspiration, and fresh, healthy recipes for summer.
Some of the most commonly consumed nightshades include:
Edible nightshades are some of the most nutritious foods around and have been consumed as part of healthy diets for centuries, says Sharon Palmer, MSFS, RDN.
Hundreds of studies have found benefits from eating these foods. In particular, tomatoes have garnished a great deal of research documenting benefits, such as antioxidant, anti-inflammatory benefits and reduced risks of diseases such as prostate cancer and heart disease, says Palmer. They have also been linked to skin and bone protection.
Meanwhile capsaicin in chile peppers may promote hair growth and reduce your cardiovascular and cancer risk. And potatoes are loaded with mood-regulating carbohydrates and muscle-building protein.
Members of the Solanaceae plant family contain alkaloids, including solanine, a natural insecticide. Solanines in belladonna, the so-called deadly nightshade, can cause delirium, hallucinations, and even death. However, the nightshades we commonly consume contain nowhere near high enough levels to cause similar harm.
There is not enough scientific support documenting that people need to avoid nightshades due to alkaloid content, says Palmer.
That being said, potato sprouts and areas of the potato that have turned green from sun exposure contain higher concentration of solanine and, therefore, should be avoided. Symptoms of solanine poisoning include abdominal pain, vomiting, diarrhea, fever or hypothermia, headaches, and a slow pulse or breathing.
Search the internet for the word nightshades, and youre bound to stumble on plenty of articles warning about inflammation and arthritis pain. But no research has turned up evidence that nightshades affect the joints.
There is a lot of urban legend and misinformation about nightshades being perpetuated over the internet and social media, says Palmer. Some people believe that they should avoid nightshades to reduce inflammation for arthritis benefits. However, studies have found that many nightshade vegetables reduce inflammation levels in the body.
Its worth noting that the Arthritis Foundation put nightshade vegetables, namely bell peppers, on its list of Best Vegetables for Arthritis. Red and yellow bell peppers contain the carotenoid beta-cryptoxanthin, which could reduce your risk of developing inflammatory disorders like rheumatoid arthritis. Additionally, tomatoes and peppers are excellent sources of bone- and cartilage-preserving vitamin C, with a single bell pepper containing more than 150% of the Food and Nutrition Boards daily recommended amount. Eggplants, meanwhile, are rich in anti-inflammatory anthocyanins as well as the essential trace element manganese, which is important to bone formation.
The scientific evidence [regarding nightshades and inflammation] isnt very strong at this time, says triple board-certified rheumatologist Micah Yu, MD, who also practices integrative medicine. Maybe in 10, 20 years, well have more evidence.
Yu notes that theres no test to determine whether someone might have a sensitivity to nightshades. If you suspect nightshades are an issue for you, he suggests keeping a food diary and seeing whether certain foods correspond with your inflammatory symptoms or other adverse reactions. You can try avoiding a food to see if symptoms improve, then reintroducing the food to see if symptoms return. If they return, its reasonable to continue avoiding the food, and consult with a registered dietitian.
At least two studies have suggested potatoes could aggravate inflammatory bowel disease. Both were performed using mice, not humans.
In one study from 2002, researchers isolated solanine and the glycoalkaloid chaconine, present in potatoes, to test intestinal permeability and function. They concluded that levels of solanine and chaconine typically found in potatoes can adversely affect a mammals intestine and exacerbate IBD.
In a 2010 study, mice were fed deep-fried potato skins. Researchers found that deep-frying the potato skins increased glycoalkaloid content and that glycoalkaloid consumption significantly aggravated intestinal inflammation in mice representing two models mimicking human IBD (interleukin 10 gene deficiency and dextran sodium sulfate-induced colitis).
But the data are limited, says Vanita Rahman, MD, clinic director of Barnard Medical Center. We know animal studies dont always translate into meaningful results in humans, so its really hard to draw any conclusions about human health, as far as inflammatory bowel disease.
Before eliminating nightshades altogether, Rahman recommends talking to a health care provider and exploring whether anything else could be contributing to IBD symptoms. Keep in mind that certain nightshadespotatoes and eggplantsare rich in fiber, which has been linked to a reduced risk of developing IBD and greater quality of life in patients with ulcerative colitis.
The bottom line is [nightshades] really are nutritious vegetables that contain a lot of important nutrients for us, says Rahman. They have a lot of health benefits. So, most people should consume them in ways that they find enjoyable.
There are plenty of opportunities to reap the health benefits of these delightful fruits and vegetables. Check out these roundups of favorite recipes from Forks Over Knives to get you started.
From baba ghanoush flatbreads to vegan eggplant parm to ratatouille, these recipes showcase eggplants melt-in-your-mouth deliciousness.

Mistletoe and the Emerging Future of Integrative Oncology – Verve Times
Posted: June 13, 2022 at 2:26 am
In this interview, Dr. Nasha Winters, coauthor of Mistletoe and the Emerging Future of Integrative Oncology, reviews some of the benefits of this ancient herb in the modern world of oncology. Winters is herself a cancer survivor, so this topic is close to her heart.
Im coming on 30 years out of a death sentence, a terminal cancer diagnosis, she says, and still to this day get met with so much resistance to what Ive learned for myself, and for thousands, if not tens of thousands, of other patients directly, as well as way more than that, indirectly, through the training of their physicians
My crazy controversy is that I focus more on the human organism and the health of that terrain versus the condition, the disease or the label that overlays that person.
Mistletoe, a semi-parasitic plant that grows in the branches of trees all over the world, has been used as a herbal medicine for thousands of years for conditions such as epilepsy, spleen disorders, pain and rheumatic conditions.
Just over 100 years ago, in 1917, Rudolf Steiner, a philosopher with incredibly keen observation skills, noticed the mistletoe looks a lot like a tumor, and proposed it might have anticancer properties. Many vitalistic medical practices, such as Ayurveda, Chinese medicine, naturopathy and homeopathy, for example, use the doctrine of signatures, which is what Steiner was suggesting.
For instance, you look at a walnut and it kind of looks like a brain and we think, I wonder if thats any good for the brain? And sure enough, we find some significance in how it impacts the brain. Or things like lungwort. When you look at it, it looks like a lung and weve learned that this herbal medicine is very helpful for lung conditions, Winters says.
A Swiss doctor named Ita Wegman applied Steiners observation of mistletoe to see how it would impact a patient with cancer, and the plant has since enjoyed over 100 years of consistent application in oncology, both standalone and as adjuvant support.
Interestingly enough Steiner understood that you needed to harvest different components of the plant berries that bloom in the winter, which is very abnormal, and the leaves that grow in the summer and grow inward.
It has a very interesting behavior compared to other plants, and that was an observation of how cancer works as well. It goes against the rhythm. It grows out of sync with the organism. That is very much what he recognized.
And as such, he harvested the plant and aspects of the plant at different times, blended it, and then took a particular extract from it. He also noted that it needed to be injected, because you need to remember, 100 years ago we didnt know about lectins, we didnt know about viscotoxins, yet somehow, he understood that you needed to inject it to get the anticancer benefit.
You could take the full tincture. You could take it in other ways, and it has a lot of other medicinal impacts, but then it doesnt have the anticancer impacts, the reason being, weve learned or at least we suspect, because were still learning is that those lectins and things get broken down in our GI tract and they dont get into the bloodstream; they dont access the immune system in the way they need to
According to Winters, mistletoe is likely to be useful as an adjunct therapy for all cancers, and she, along with several other doctors, has been training physicians on how to use mistletoe for several years now.
One of our physicians has been using mistletoe for 45 years in his practice, and what weve seen clinically, and what the research suggests, is that this therapy, it has always been about using it with others. It plays very well with others.
It was never really developed to be a standalone therapy, though believe me, weve seen impact with that as well. And it has virtually no contraindications with any of our standard of care therapies. So, we can literally inject this into a patient the morning before they go into a surgery, or they can start on this therapy the very day theyre going to start a round of chemotherapy or radiation.
It bypasses first phase detox pathways of the liver, so it doesnt interact, intervene, speed up or slow down detox processes that could otherwise cause some adverse events, or change the desired effect of a certain medication, herbal intervention or dietary intervention.
In fact, mistletoe has been shown to enhance other interventions. Even the most toxic treatments seemingly work better and with fewer adverse effects when combined with mistletoe.
This should be utilized, in my personal opinion, with every patient going through a standard of care approach to just enhance their experience with treatment, she says.
There are a lot of things that we kind of have to be careful with but mistletoe, in my experience, and that of my colleagues, is that this is probably the least harmful and least contraindicated substance and therapy Ive ever had the privilege of working with. Its pretty extraordinary and rare to find something that is this applicable to the masses
As I said, it has over 100 years of continuous use, and has over 250 very good randomized studies It just completed a Phase 1 clinical trial at Johns Hopkins in the United States as an IV application for solid tumors, and is getting ready to be moved into a Phase 2 clinical trial.
It is the most studied integrative oncology therapy in the world, and it is utilized in upwards of 60% to 80% of all cancer patients in Europe. In parts of South and Central America, all over Southeast Asia and India, in different parts of Europe, this is just part of their medical system Its just in the United States where we have a little bit of resistance to embracing it into our conventional medical system
As a naturopathic physician whos been practicing integrative oncology for some time and who has teachers, mentors, colleagues from all over the world, some of the most powerful anticancer therapies Ive seen that are beneficial even to the standard of care model of treatment things like artesunate, curcumin, quercetin, green tea extract, all of those in intravenous forms have been taken out of our ability to use here in the United States.
Do my colleagues still find workarounds to get access to these very important medicines? Absolutely they do, but they have to tread very carefully and very lightly. But again, you go north of the border or south of the border and you have no problem accessing these therapies. Or go to Europe and this is what Ive been doing for the last two years.
These treatments that weve had great success with have been plucked out of our ability to access easily, readily, legally, so were now having to send our patients abroad for them to actually get good cancer care.
Thats whats really devastating to me. So, another part of my purpose and mission is to build an in-house residential research institute and integrative cancer hospital right here on our soil so we dont lose access and patients dont lose access [to helpful remedies].
Winters is currently building that research institute in Arizona, which will be funded entirely by private donations and research grants. Thousands of patients are anxiously waiting for the doors to open. When asked if she isnt worried our pro-pharma agencies might shut them down, she replies:
We will be doing all of our due diligence to let people know that these are not FDA approved therapies, that people are coming into a research environment. Theyre either paying cash or theyre getting grants based on their financial ability to help them cover this care.
Were doing it in a pretty open-minded medical state; Arizona has one of the broadest scopes of practice in the country. And were also very close to our southern border with Mexico, so that if we do come up against someone shutting down one of our therapies for a bit, we are able to take our patients across the border to a little sister clinic to keep the continuity of care.
We dont anticipate that happening because people are coming as a buyer beware. Theyre coming being well-informed about who we are and what were about. And frankly, we get thousands of inquiries a month from all over the world looking for this approach. The patients will drive this home.
Its a mighty David versus Goliath story, especially now, but I also think the time is now because we have these acts, like the Right to Try Act, and because we do have more and more patients facing this diagnosis with grim outcomes.
And, a study that came out in the last year that looked at 17 years worth of conventional cancer treatments found that, overall, of the 96 different drugs they looked at, the average survival rate was 2.4 months. That is the reality and this is whats driving the clinical oncologists from around the world to sign up and take my course
So, there is this massive kind of underground movement thats starting to sprout and come above ground. Thats happening. And frankly, mistletoe is one of the vehicles for that to happen Instead of trying to fix the model, were just creating a new one.
Another potential back door is to convince insurance companies that this is in their best interest. Mistletoe is a natural remedy and therefore cannot be patented, so theres no incentive for the drug companies to pursue it. But insurance companies may support its use once they realize how much money they can save on hospitalizations, drug coverage and everything else.
Your immune system and metabolic function are both integral parts of addressing cancer, and mistletoe works on both. Its important to recognize, however, that its not a magic bullet. If youre eating a standard American diet and are metabolically dysfunctional, mistletoe is not going to be as effective as for someone who is also eating a healthy whole food diet and supporting their health in other ways.
That said, mistletoe is an immunomodulator. Immune therapies are all the rage right now, with a majority of research dollars being funneled into them. Yet the effectiveness rate for these therapies is less than 20%. In other words, theyre hardly a cure.
A lot of folks have heard of Jimmy Carters melanoma story that had metastasized to his brain. He took this immune drug, Keytruda. Thats a checkpoint inhibitor. The most common drugs youll hear about are things like Opdivo, Keytruda, PD-1, PDL1 inhibitors, those are checkpoint inhibitors, or CTLA-4 inhibitors, also a type of checkpoint inhibitor.
These are drugs that kind of pull the breaks off your immune system to go hog wild in treating the cancer. Now that seems like a great idea unless you have underlying metabolic dysfunction, right? Hello! And then, if you have an underlying autoimmune condition, you are also someone whos likely going to have a not so positive response to these medications.
What I love about mistletoe is it comes in and it modulates that teeter-totter. It doesnt take the breaks off and make it go hog wild, and it doesnt suppress. Its kind of adaptogenic in some ways. So, it behaves a little bit like a smart drug, in that it can sort of match itself to the individual.
It is not a protocol, its a patient-driven process in that we look at the persons gender, we look at the tumor type, the tumor stage, the general condition of the patient, and then we consider the most appropriate host tree. The most common are the pine, the fir, and the apple tree hosts. Mistletoe [from these trees] tends to have the highest lectin content that have the highest anti-cancer content.
Then we look at the dosing frequency, and if were going to do it subcutaneous, intravenous, intratumoral, intraperitoneal, et cetera, depending on where you live in the world and how were going to pair it with other therapies, if at all. So, it is based totally on the individual and the individuals response.
We want the patient to have a little local reaction if theyre injecting it. We want it to get a little redness, irritation and itchiness and maybe tenderness. We want it to raise the bodys temperature a little bit The point is, we want to create this cytokine release at a very low-grade level. Whereas when we bring on an immune drug like Keytruda, it creates a cytokine release at an explosive level that can sometimes be fatal for patients.
Similar to drugs, mistletoe also has a systemic effect. It doesnt target a specific receptor site. Instead, its a systemic terrain-centric approach. In its mechanisms of action, its engaging with B-cells, T-cells, natural killer (NK) cells.
It will basically calm those that are acting overzealous, to prevent an excessive immune reaction, and activate those that are dormant or underperforming. Mistletoe also reduces inflammation, lowering your levels of C-reactive protein, interleukin-6, homocysteine, liver enzymes and more.
It also lowers vascular endothelial growth factor (VEGF), which can be important for certain cancers, and it lowers blood sugar and insulin. Winters also suspects mistletoe may be upregulating both the endorphin and the endocannabinoid system, so youre getting stress modulation as well.
So, its hitting all of what we call The Terrain 10, from my previous book, The Metabolic Approach to Cancer. I find that mistletoe tends to hit every one of those including epigenetic expression clean up of DNA.
We use it for people whove gone through radiation. Well use it as a DNA stabilizer. Well use it if people have taken a course of Cipro [and other fluoroquinolones] to help clean up the metabolic mayhem, the DNA damage that they cause. We know that it has some impact on insulin and IGF-1.
In our book, we have hundreds of references to all of the different mechanisms of action. My colleague, Dr. Paul Faust, [has written] a beautiful chapter on its direct impact on the immune system and all the nuances of that.
That chapter alone will illuminate for so many people why this therapeutic support and this therapeutic intervention is so helpful for the cancer patient, for prevention of cancer, for cleanup after cancer treatment
And the synergy, when you pair mistletoe with hyperthermia, like so many of my colleagues in Europe have been doing for the past 50 years, talk about the biggest bang for your buck. We see some pretty extraordinary outcomes.
Ive had patients go to Europe with Stage 4 [cancer], metastatic disease everywhere, getting IV mistletoe along with local, regional and whole body high-heat hyperthermia that have put their cancer into complete remission in many cases, but at the very least, turning it back into a manageable disease process, and even more interesting, increasing the responsivity to other therapies again.
The good news is the number of doctors trained in this therapy is growing, and the treatment itself is only between $200 and $300 a month, so its highly affordable while also being highly effective. I think it would be beyond irrational not to integrate this into any cancer therapy youre considering.
Again, for cancer, oral supplementation is ineffective, as the lectins responsible for the anticancer effects are broken down in your GI tract and therefore cant enter your bloodstream.
The Physicians Association for Anthroposophic Medicine (PAAM) sponsors Winters mistletoe trainings. While most are held in person, theres now also a course available online for licensed physicians. There are plans to take a group of physicians to Europe for immersive in-hospital training in the fall of 2023. Heres a list of resources where you can find more information:
AnthrosophicMedicine.org offers articles, research, books, webinars and more. To locate a clinician trained in the proper administration of mistletoe, see PAAMs health provider directory.
Clinicians interested in training, visit the education section of PAAMs website. The next annual training conference will be held in Loveland, Colorado, April 29 through May 6, 2023.
Metabolic Terrain Institute of Health (MTIH) is the not-for-profit association cofounded by Winters that is building a research hospital in Arizona. MTIH also offers a master course for practitioners, and grants to help patients access these therapies. Certified practitioners can be found on terrain.network.
These practitioners include medical doctors and oncologists who have been taught Winters methodology of testing, assessing and treating cancer (which includes but is not limited to mistletoe therapy). MTIH certified practitioners are also listed on DrNasha.com.
Mistletoe-therapy.org is a European website that offers helpful information for patients and scientific papers directed at clinicians.
A load of resources are found on the books website: http://www.themistletoebook.com. Proceeds from this book go to fund clinical research and contribute to physician training.
Last but certainly not least, youll want to pick up a copy of Mistletoe and the Emerging Future of Integrative Oncology. Its an excellent book.

Scientists hope this injectable stem cell gel can repair heart attack damage and avoid transplants – Euronews
Posted: June 13, 2022 at 2:24 am
Researchers in the UK have developed a biodegradable hydrogel that could help repair the damage caused by heart attacks.
The gel is used as a binding agent to inject stem cells into the heart. These cells can then regenerate and rebuild areas where the tissue is damaged.
So far, the gel has only been tested in healthy mice. But scientists at the University of Manchester say its showing promising results and they hope it can become a key part of future regenerative treatments.
According to the World Health Organization (WHO) and the Lancet Burden of Disease, over nine million people each year die from coronary heart disease, the most common cause of heart failure, despite significant advances in heart surgery.
During a heart attack, blood and oxygen are cut off from the heart, which can cause muscle cells to die. Depending on the severity of the damage, patients can require a heart transplant - a complicated, invasive, and risky procedure.
The team at the University of Manchester is hoping the new gel technology can ultimately improve regenerative treatments and avoid heart transplants altogether.
Stem cell surgery has already been widely used to generate tissue. In Switzerland, surgeons have grown stem cells into cartilage and transplanted them into damaged knees.
However, successes with the heart have been more elusive. In the past, surgeons have tried to inject stem cells directly into the heart, but the cells have not survived.
"The challenges in injecting these cells into a beating heart is that the heart is a mechanical structure and that the cells, if they're injected alone, find it very difficult to find an anchor, said Professor James Leiper, Associate Medical Director at the British Heart Foundation, which funded the research.
This hydrogel is an exciting potential mechanism that we could use to really harness the regenerative capacity of stem cells".
The team at the University of Manchester says the gel can be safely injected into the beating heart to act as a scaffold for stem cells to grow new tissue.
The gel is made of chains of amino acids called peptides, the building blocks of proteins.
To prove it could work in a living heart, the team injected the gel with a fluorescent tag into the hearts of healthy mice.
The fluorescent tag revealed that the gel remained in the heart for two weeks, while ultrasounds and electrocardiograms showed the injection was safe.
Lead researcher Katharine King says this shows the cells can be held inside the hearts long enough for the stem cells to start growing.
"It's looking very promising, the way that it would stay there and be able to hold the cells there long enough for them to kind of integrate into the heart," she said.
The researchers now plan to trial the gel in mice straight after a heart attack, to see whether the heart cells can develop new muscle tissue and help restore the hearts ability to pump efficiently.
Only if trials on animals are successful will scientists be able to conduct further clinical studies to assess whether the gel can safely and effectively be used in humans, a process that typically takes several years.
"If the benefits are replicated in further research and then in patients, these gels could become a significant component of future treatments to repair the damage caused by heart attacks," Leiper said.

Axol Bioscience Introduces CiPA-Validated Human Stem Cell-Derived Ventricular Cardiomyocytes to Help Improve Drug Discovery – Business Wire
Posted: June 13, 2022 at 2:24 am
CAMBRIDGE, England & EDINBURGH, Scotland--(BUSINESS WIRE)--Axol Bioscience Ltd. (Axol), an established provider of iPSC-derived cells, media, and characterization services for life science discovery, today announced that its human induced pluripotent stem cell (iPSC)-derived ventricular cardiomyocytes have undergone comprehensive in vitro pro-arrhythmia assay (CiPA) validation. Using this assay, the cells were shown to be suitable for measuring cardiotoxicity, offering scientists a robust cardiac model for drug discovery and screening.
Axols human iPSC-derived ventricular cardiomyocytes are manufactured at scale according to strict quality control standards using ISO 9001-accredited quality management systems, providing a continuous source of cells from the same genetic background for use in multiple experiments. This offers a physiologically relevant in vitro research model of human heart cells to reliably and repeatably test drug candidates for cardiotoxicity at scale.
With the advent of human iPSC-derived cardiomyocytes, the US Federal Food and Drug Administration Agency (FDA) launched a working group to assess the utility of these cells in reproducing cardiotoxicity in a dish, known as CiPA*. The assay tests cells with 28 compounds that are known to be cardiotoxic and induce the fatal arrhythmia Torsades de Pointes. Clyde Biosciences, a CRO that specializes in cardiotoxicity assays, used this assay to validate Axols cardiomyocytes for cardiac safety testing. Using these cells could help researchers to identify unsuitable drug candidates earlier in the drug discovery process and improve the number of promising pre-clinical drug candidates that translate through to clinical trials and to patients.
Liam Taylor, CEO, Axol Bioscience, said: Scientists need cells and reagents they can rely on to make meaningful assessments of drug candidate toxicity, before progressing candidates to the clinic.
Were both excited and proud to demonstrate the suitability of our human iPSC-derived ventricular cardiomyocytes for toxicity testing. Axols stringent quality control standards mean we have the capability to produce reliable, validated cells that scientists can use to assess a compounds cardiac liability and, ultimately, help to improve the drug discovery process.
Prof. Godfrey Smith, CSO, Clyde Biosciences, added: As a core member of the CiPA initiative, were pleased to have supported Axols cell development and helped the team assess the performance of its cardiomyocytes. Having run the CiPA protocol on Clydes proprietary CellOPTIQ platform, and provided analysis and interpretation of the data, we confirm our data indicates that Axols cardiomyocytes meet the requirements for predictive in vitro pro-arrhythmia screening.

Fasting has pros and cons for muscle repair in mice – Futurity: Research News

Fasting sends muscle stem cells into a deep resting state that slows muscle repair but also makes them more resistant to stress, according to a study of laboratory mice.
The protective effect can also be achieved by feeding the mice high-fat, low-carbohydrate foodalso known as a ketogenic dietthat mimics how the body responds to fasting, or by giving the animals ketone bodies, the byproducts that occur when the body uses fat as an energy source.
The research explores how the body responds in times of deprivation and plenty and gives clues about the effect of aging on the ability to regenerate and repair damaged tissue. Although the study focused on muscle stem cells, the researchers believe the findings are applicable to other types of tissue throughout the body.
As we age, we experience slower and less complete healing of our tissues, says Thomas Rando, professor of neurology and neurological sciences at Stanford University. We wanted to understand what controls that regenerative ability and how fasting impacts this process. We found that fasting induces resilience in muscle stem cells so that they survive during deprivation and are available to repair muscle when nutrients are again available.
Rando, who recently accepted a position as the director of the Broad Stem Cell Research Center at UCLA, is the senior author of the study in Cell Metabolism. Instructor Daniel Benjamin and graduate student Pieter Both are the lead authors of the study.
Its been well documented that long-term caloric restriction extends the lifespan and promotes the overall health of laboratory animals, but it is difficult for people to maintain a very-low-calorie diet for months or years. Periodic fasting has been explored as another way to obtain the health benefits of caloric restriction, but the effects of intermittent fasting on the body and its ability to regenerate damaged or aging tissues have not been well studied.
Fasting or, alternatively, eating a ketogenic diet high in fat and low in carbohydratesa popular weight-loss techniquecauses the body to enter a state called ketosis, in which fat is the primary energy source. Ketone bodies are the byproducts of fat metabolism.
The researchers found that mice that had fasted between 1 and 2.5 days were less able than non-fasting animals to regenerate new muscle in their hind legs in response to injury. This reduced regenerative capacity persisted for up to three days after the mice began feeding again and returned to a normal body weight; it returned to normal within one week of the end of the fast.
Further research showed that muscle stem cells from fasting animals were smaller and divided more slowly than those from non-fasting animals. But they were also more resilient: They survived better when grown on a lab dish under challenging conditions including nutrient deprivation, exposure to cell-damaging chemicals, and radiation. They also survived transplantation back into animals better than those from non-fasting animals.
Usually, most laboratory-grown muscle stem cells die when transplanted, Rando says. But these cells are in a deep resting state we call ketone-induced deep quiescence that allows them to withstand many kinds of stress.
Muscle stem cells isolated from non-fasting animals and then treated with a ketone body called beta-hydroxybutyrate (BHB) displayed a similar resilience as did those from fasting animals, the researchers found. Additionally, muscle stem cells isolated from mice fed a ketogenic diet, or a normal diet coupled with injections of ketone bodies, displayed the same characteristics of the deeply quiescent stem cells from fasting animals.
Finally, the researchers isolated muscle stem cells from old mice that had been treated with ketone bodies for one week. Previous research in Randos lab showed that these aged muscle stem cells grew more poorly in the laboratory than muscle stem cells from younger animals. But treatment with the ketone bodies allowed the old muscle stem cells to survive as well as their younger counterparts.
Although more research needs to be done, the results are intriguing, the researchers say.
Cells evolved to exist in times of abundance and in times of deprivation, Rando says. They had to be able to survive when food was not readily available. Ketone bodies arise when the body uses fat for energy, but they also push stem cells into a quiescent state that protects them during deprivation. In this state, they are protected from environmental stress, but they are also less able to regenerate damaged tissue.
Balancing these outcomes might one day help combat normal aging and enhance stem cell function throughout the body, the researchers speculate.
It would be beneficial if the effects of fasting on stem cells could be attained through ketone bodies, supplanting the need to fast or to eat a ketogenic diet, Rando says. Perhaps it may be possible to eat normally and still get this increased resilience.
The National Institutes of Health, the Buck Institute for Research on Aging, and the Department of Veterans Affairs supported the work.
Researchers from UC Berkeley, the Veterans Affairs Palo Alto Health Care System, and the Mondor Institute for Biomedical Research in France are coauthors of the study.
