The Best-Laid Schemes of Mice and Medical Researchers…

This is Dr. Ellen Heber-Katz. She’s an internationally-renowned immunologist and regeneration biologist, but her perhaps greatest discovery was accidental.

Unlike in Robert Burns’ famous poem, this one has a happy ending!

But it did involve the best-laid schemes of mice and medical researchers, and how they did indeed “gang gagly“ (or in the English translation, “go awry”).

How it started…

Back in 1995, she was conducting autoimmune research, and doing a mouse study. Her post-doc assistant was assigned to punch holes in the ears of mice that had received an experimental treatment, to distinguish them from the control group.

However, when the mice were later checked, none of them had holes (nor even any indication there ever had been holes punched)—the experiment was ruined, though the post-doc swore she did her job correctly.

So, they had to start from scratch in the new year, but again, a second batch of mice repeated the trick. No holes, no wounds, no scarring, not disruption to their fur, no damage to the cartilage that had been punched through.

In a turn of events worthy of a superhero origin story, they discovered that their laboratory-made autoimmune disease had accidentally given the mice super-healing powers of regeneration.

In the animal kingdom, this is akin to a salamander growing a new tail, but it’s not something usually found in mammals.

How it’s going…

Dr. Heber-Katz and colleagues took another 20 years of work to isolate hypoxia-inducible factor-1a (HIF-1a) as a critical molecule that, if blocked, would eliminate the regenerative response.

Further, a drug (which they went on to patent), 1,4-dihydrophenonthrolin-4-one-3-carboxylic acid (1,4-DPCA), chemically induced this regenerative power:

See: Drug-induced regeneration in adult mice

Another 5 years later, they found that this same drug can be used to stimulate the regrowth of bones, too:

An injectable hydrogel-formulated inhibitor of prolyl-4-hydroxylase promotes T regulatory cell recruitment and enhances alveolar bone regeneration during resolution of experimental periodontitis

And now…

The research is continuing. Here’s the latest, a little over a month ago:

Epithelial–mesenchymal transition: an organizing principle of mammalian regeneration

Regrowing nerves has also been added into the list of things the drug can do.

What about humans?

Superpowered mice are all very well and good, but when can we expect this in humans?

The next step is testing the drug in larger animals, which she hopes to do next year, followed eventually by studies in humans.

  • The Telomere Effect – by Dr. Elizabeth Blackburn and Dr. Elissa Epel

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Telomeres can be pretty mystifying to the person with a lay interest in longevity. Beyond “they’re the little caps that sit on the end of your DNA, and longer is better, and when they get short, damage occurs, and aging”, how do they fit into the big picture?

    Dr. Elizabeth Blackburn and Dr. Elissa Epel excel at explaining the marvelous world of telomeres…

    • how they work
    • what affects them
    • and how and why

    …and the extent to which changes are or aren’t reversible.

    For some of us, the ship has sailed on avoiding a lot of early-life damage to our telomeres, and now we have a damage-mitigation task ahead. That’s where the authors get practical.

    Indeed, the whole third part of the book is titled “Help Your Body Protect Its Cells“, and indeed covers not just “from now on” protection, but undoing some of the damage already done (yes, telomeres can be lengthened—it gets harder as we get older, but absolutely can be done).

    In short: if you’d like to avoid further damage to your telomeres where possible, and reverse some of the damage done already, this book will set you on the right track.

  • Codependency Isn’t What Most People Think It Is

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Codependency isn’t what most people think it is

    In popular parlance, people are often described as “codependent” when they rely on each other to function normally. That’s interdependent mutualism, and while it too can become a problem if a person is deprived of their “other half” and has no idea how to do laundry and does not remember to take their meds, it’s not codependency.

    Codependency finds its origins in the treatment and management of alcoholism, and has been expanded to encompass other forms of relationships with dependence on substances and/or self-destructive behaviors—which can be many things, including the non-physical, for example a pattern of irresponsible impulse-spending, or sabotaging one’s own relationship(s).

    We’ll use the simplest example, though:

    • Person A is (for example) an alcoholic. They have a dependency.
    • Person B, married to A, is not an alcoholic. However, their spouse’s dependency affects them greatly, and they do what they can to manage that, and experience tension between wanting to “save” their spouse, and wanting their spouse to be ok, which latter, superficially, often means them having their alcohol.

    Person B is thus said to be “codependent”.

    The problem with codependency

    The problems of codependency are mainly twofold:

    1. The dependent partner’s dependency is enabled and thus perpetuated by the codependent partner—they might actually have to address their dependency, if it weren’t for their partner keeping them from too great a harm (be it financially, socially, psychologically, medically, whatever)
    2. The codependent partner is not having a good time of it either. They have the stress of two lives with the resources (e.g. time) of one. They are stressing about something they cannot control, understandably worrying about their loved one, and, worse: every action they might take to “save” their loved one by reducing the substance use, is an action that makes their partner unhappy, and causes conflict too.

    Note: codependency is often a thing in romantic relationships, but it can appear in other relationships too, e.g. parent-child, or even between friends.

    See also: Development and validation of a revised measure of codependency

    How to deal with this

    If you find yourself in a codependent position, or are advising someone who is, there are some key things that can help:

    • Be a nurturer, not a rescuer. It is natural to want to “rescue” someone we care about, but there are some things we cannot do for them. Instead, we must look for ways to build their strength so that they can take the steps that only they can take to fix the problem.
    • Establish boundaries. Practise saying “no”, and also be clear over what things you can and cannot control—and let go of the latter. Communicate this, though. An “I’m not the boss of you” angle can prompt a lot of people to take more personal responsibility.
    • Schedule time for yourself. You might take some ideas from our previous tangentially-related article:

  • Why We’re Called “10almonds”, And Other Questions

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    It’s Q&A Day at 10almonds!

    Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!

    In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!

    As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!

    So, no question/request too big or small

    ❝Avid coffee drinker so very interested in the results Also question Is there something that you could take or eat that would prevent the caffeine from stimulating the kidneys? I tried to drink decaf from morning to night not a good result! Thanks❞

    That is a good question! The simple answer is “no” (but keep reading, because all is not lost)

    There’s no way (that we yet know of) to proof the kidneys against the stimulating effect of caffeine. This is especially relevant because part of caffeine’s stimulating effect is noradrenergic, and that “ren” in the middle there? It’s about the kidneys. This is just because the adrenal gland is situated next to them (actually, it’s pretty much sitting on top of them), hence the name, but it does mean that the kidneys are about the hardest thing in the body to have not effected by caffeine.

    However! The effects of caffeine in general can be softened a little with l-theanine (found in tea, or it can be taken as a supplement). It doesn’t stop it from working, but it makes the curve of the effect a little gentler, and so it can reduce some unwanted side effects.

    You can read more about l-theanine here:

    L-Theanine: What’s The Tea?

    ❝How to jump start a inactive metabolism and keep it going? THANKYOU❞

    The good news is, if you’re alive, your metabolism is active (it never stops!). So, it may just need perking up a little.

    As for keeping it going, well, that’s what we’re here for! We’re all in favor of healthy longevity.

    We’ll do a main feature soon on what we can do to influence our metabolism in either direction, but to give some quick notes here:

    • A lot of our metabolism is influenced by genes and is unalterable (without modifying our genes, anyway)
    • Metabolism isn’t just one thing—it’s many. And sometimes, parts of our metabolism can be much quicker or slower than others.
    • When people talk about wanting a “faster metabolism”, they’re usually referring to fat-burning, and that’s just a small part of the picture, but we understand that it’s a focal point for many.

    There really is enough material for a whole main feature on metabolic tweaks, though, so watch this space!

    ❝Why the name “10 Almonds?” Is this recommended by the Doctor? A daily dosage? And, if so, why? Thanks! Please answer me…I truly want to know!❞

    Almonds are very nutritionally dense, and for example 20g of almonds (so, about 20 almonds) would give a 100% daily dose of zinc, amongst other nutrients.

    We also do like to think that we give our readers an easily digestible dose of condensed “nutrition” in the form of health information.

    However! That’s not actually the reason at all. It’s a reference to a viral Facebook hoax! There was a post going around that claimed:

    ❝HEADACHE REMEDY. Eat 10–12 almonds, the equivalent of two aspirins, next time you have a headache❞ ← not true!

    It made us think about how much health-related disinformation there was circulating online! So, calling ourselves 10almonds was a bit of a nod to that story, but also a reminder to ourselves:

    We must always publish information with good scientific evidence behind it!

    There are a lot of books about addiction, so what sets this one apart?

    Mostly, it’s that this one maintains that addiction is neither good nor bad per se—just, some behaviors and circumstances are. Behaviors and circumstances caused, directly or indirectly, by addiction.

    But, Dr. Linden argues, not every addiction has to be so. Especially behavioral addictions; the rush of dopamine one gets from a good session at the gym or learning a new language, that’s not a bad thing, even if they can fundamentally be addictions too.

    Similarly, we wouldn’t be here as a species without some things that rely on some of the same biochemistry as addictions; orgasms and eating food, for example. Yet, those very same urges can also inconvenience us, and in the case of foods and other substances, can harm our health.

    In this book, the case is made for shifting our addictive tendencies to healthier addictions, and enough information is given to help us do so.

    Bottom line: if you’d like to understand what is going on when you get waylaid by some temptation, and how to be tempted to better things, this book can give the understanding to do just that.

  • What does it mean to be immunocompromised?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our immune systems help us fight off disease, but certain health conditions and medications can weaken our immune systems. People whose immune systems don’t work as well as they should are considered immunocompromised.

    Read on to learn more about how the immune system works, what causes people to be immunocompromised, and how we can protect ourselves and the immunocompromised people around us from illness.

    What is the immune system?

    The immune system is a network of cells, organs, and chemicals that helps our bodies fight off infections caused by invaders, such as bacteria, viruses, fungi, and parasites.

    Some important parts of the immune system include: 

    • White blood cells, which attack and kill germs that don’t belong inside our bodies. 
    • Lymph nodes, which help our bodies filter out germs. 
    • Antibodies, which help our bodies recognize invaders.
    • Cytokines, which tell our immune cells what to do.

    What causes people to be immunocompromised?

    Some health conditions and medications can prevent our immune systems from functioning optimally, which makes us more vulnerable to infection. Health conditions that compromise the immune system fall into two categories: primary immunodeficiency and secondary immunodeficiency.

    Primary immunodeficiency

    People with primary immunodeficiency are born with genetic mutations that prevent their immune systems from functioning as they should. There are hundreds of types of primary immunodeficiencies. Since these mutations affect the immune system to varying degrees, some people may experience symptoms and get diagnosed early in life, while others may not know they’re immunocompromised until adulthood.

    Secondary immunodeficiency

    Secondary immunodeficiency happens later in life due to an infection like HIV, which weakens the immune system over time, or certain types of cancer, which prevent the body from producing enough white blood cells to adequately fight off infection. Studies have also shown that getting infected with COVID-19 may cause immunodeficiency by reducing our production of “killer T-cells,” which help fight off infections.

    Sometimes necessary treatments for certain medical conditions can also cause secondary immunodeficiency. For example, people with autoimmune disorders—which cause the immune system to become overactive and attack healthy cells—may need to take immunosuppressant drugs to manage their symptoms. However, the drugs can make them more vulnerable to infection. 

    People who receive organ transplants may also need to take immunosuppressant medications for life to prevent their body from rejecting the new organ. (Given the risk of infection, scientists continue to research alternative ways for the immune system to tolerate transplantation.)

    Chemotherapy for cancer patients can also cause secondary immunodeficiency because it kills the immune system’s white blood cells as it’s trying to kill cancer cells.

    What are the symptoms of a compromised immune system?

    People who are immunocompromised may become sick more frequently than others or may experience more severe or longer-term symptoms than others who contract the same disease.

    Other symptoms of a compromised immune system may include fatigue; digestive problems like cramping, nausea, and diarrhea; and slow wound healing.

    How can I find out if I’m immunocompromised?

    If you think you may be immunocompromised, talk to your health care provider about your medical history, your symptoms, and any medications you take. Blood tests can determine whether your immune system is producing adequate proteins and cells to fight off infection.

    I’m immunocompromised—how can I protect myself from infection?

    If you’re immunocompromised, take precautions to protect yourself from illness.

    Wash your hands regularly, wear a well-fitting mask around others to protect against respiratory viruses, and ensure that you’re up to date on recommended vaccines.

    Immunocompromised people may need more doses of vaccines than people who are not immunocompromised—including COVID-19 vaccines. Talk to your health care provider about which vaccines you need.

    How can I protect the immunocompromised people around me?

    You never know who may be immunocompromised. The best way to protect immunocompromised people around you is to avoid spreading illnesses. 

    If you know you’re sick, isolate whenever possible. Wear a well-fitting mask around others—especially if you know that you’re sick or that you’ve been exposed to germs. Make sure you’re up to date on recommended vaccines, and practice regular hand-washing.

    If you’re planning to spend time with someone who is immunocompromised, ask them what steps you can take to keep them safe.

    For more information, talk to your health care provider.

  • Sprout Your Seeds, Grains, Beans, Etc

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Good Things Come In Small Packages

    “Sprouting” grains and seeds—that is, allowing them to germinate and begin to grow—enhances their nutritional qualities, boosting their available vitamins, minerals, amino acids, and even antioxidants.

    You may be thinking: surely whatever nutrients are in there, are in there already; how can it be increased?

    Well, the grand sweeping miracle of life itself is beyond the scope of what we have room to cover today, but in few words: there are processes that allow plants to transform stuff into other stuff, and that is part of what is happening.

    Additionally, in the cases of some nutrients, they were there already, but the sprouting process allows them to become more available to us. Think about the later example of how it’s easier to eat and digest a ripe fruit than an unripe one, and now scale that back to a seed and a sprouted seed.

    A third way that sprouting benefits us is by reducing“antinutrients”, such as phytic acid.

    Let’s drop a few examples of the “what”, before we press on to the “how”:

    Sounds great! How do we do it?

    First, take the seeds, grains, nuts, beans, etc that you’re going to sprout. Fine examples to try for a first sprouting session include:

    • Grains: buckwheat, brown rice, quinoa
    • Legumes: soy beans, black beans, kidney beans
    • Greens: broccoli, mustard greens, radish
    • Nuts/seeds: almonds, pumpkin seeds, chia seeds

    Note: whatever you use should be as unprocessed as possible to start with:

    • On the one hand, you’d be surprised how often “life finds a way” when it comes to sprouting ridiculous choices
    • On the other hand, it’s usually easier if you’re not trying to sprout blanched almonds, split lentils, rolled oats, or toasted hulled buckwheat.

    Second, you will need clean water, a jar with a lid, muslin cloth or similar, and a rubber band.

    Next, take an amount of the plants you’ll be sprouting. Let’s say beans of some kind. Try it with ¼ cup to start with; you can do bigger batches once you’re more confident of your setup and the process.

    Rinse and soak them for at least 24 hours. Take care to add more water than it looks like you’ll need, because those beans are thirsty, and sprouting is thirsty work.

    Drain, rinse, and put them in a clean glass jar, covering with just the muslin cloth in place of the lid, held in place by the rubber band. No extra water in it this time, and you’re going to be storing the jar upside down (with ventilation underneath, so for example on some sort of wire rack is ideal) in a dark moderately warm place (e.g. 80℉ / 25℃ is often ideal, but it doesn’t have to be exact, you have wiggle-room, and some things will enjoy a few degrees cooler or warmer than that)

    Each day, rinse and replace until you see that they are sprouting. When they’re sprouting, they’re ready to eat!

    Unless you want to grow a whole plant, in which case, go for it (we recommend looking for a gardening guide in that case).

    But watch out!

    That 80℉ / 25℃ temperature at which our sprouting seeds, beans, grains etc thrive? There are other things that thrive at that temperature too! Things like:

    • E. coli
    • Salmonella
    • Listeria

    …amongst others.

    So, some things to keep you safe:

    1. If it looks or smells bad, throw it out
    2. If in doubt, throw it out
    3. Even if it looks perfect, blanch it (by boiling it in water for 30 seconds, before rinsing it in cold water to take it back to a colder temperature) before eating it or refrigerating it for later.
    4. When you come back to get it from the fridge, see once again points 1 and 2 above.
    5. Ideally you should enjoy sprouted things within 5 days.
