A Homeopathic Defence Against COVID-19 Is No Defence at All – The Wire

Arsenicum album 30C (Aa30C) is a homeopathic drug that Indias Ministry of AYUSH prescribed through an advisory on March 6, in the context of the COVID-19 pandemic. In section i. Preventive and prophylactic and sub-section Homoeopathy, the ministry advised the recommended dose thus: Arsenicum album 30, daily once in empty stomach for three days.

To make the drug, a mother tincture of the medicine is first made by dissolving by arsenic trioxide in a mixture of glycerine, alcohol and water or sometimes by heating arsenic with water. One millilitre of this tincture is diluted with 99 ml of water plus ethyl alcohol, and given a few machine-operated, moderate, equal and successive jerks, called succussions. This leads to a 100-fold dilution. The process is repeated 30-times to produce the final product, of 30C potency. A few drops of this, loaded on sugar pills, is administered to an individual. Apparently, each dilution plus succussion step makes the formulation more potent, and the process is called potentisation.

Starting with a mother tincture that has 200 grams of arsenic trioxide in 1 litre of liquid, the 30C potency medicine has one molecule of the active material present in a volume equivalent to that of 1 million Suns. In terms of the active material, an individual is consuming zero molecules.

However, this should not surprise us. Homeopathy was first proposed in Germany by Samuel Hahnemann (1755-1843) as an alternate medicinal strategy, more than 200 years ago. This was a time when the chemistry to show the above effect was not known (now it is in school textbooks). This was also an era where orthodox medicine was crude, often involving blood-letting. Compared to this, homeopathy seemed safe and humane. But today, when science has since made numerous strides, it is problematic that homeopathic principles still evade the rigours of scientific questioning.

From nothingness to water memory

Homeopathy takes recourse in the notion that water, when it comes in contact with the active material, develops molecular memory. In the absence of this active material in the final formulation, it is this memory-laden water that triggers an immune response in the human body. Note that the active material arsenic, in this case is chosen based on the homeopathic law of similars, i.e. a substance that induces the symptoms of a disease.

Unfortunately, there is no evidence of water having any kind of memory. Even the journal Nature was touched by this controversy. It should also strike us that if water remembered what it touched, it would have lots of memories of anything it touched.

Any scientific response to such lack of evidence should be rigorous experimentation to demonstrate effects, or the lack of it. However, the actual response to any critique of homeopathy has often been that science does not know everything yet.

The quest to explain how homeopathy works has also led to hypotheses that suggest the active material somehow survives in even the most dilute homeopathic medicines. Here, the original active material finds its way into the final drug via interaction of the drug and bubbles formed during succussions. However, the methods used in the study are not standard for potentisation. The physics of bubbles catching the active material is unclear, and control experiments like checking for contaminants were not performed.

More importantly, even if traces of active material are present, how do they trigger physiology to act against an external agent (like the novel coronavirus)? We dont know. For a chemical to be accepted as a drug, it takes years of experimentation, involving laboratory experiments, animal trials and human trials over multiple phases. But proponents of homeopathy have claimed that it cannot be subjected to such trials because it provides highly individualised doses. However, the mass distribution of Aa30C is anything but individualised.

Most popular narratives on homeopathy consist of anecdotes and scientific-sounding terms like vital force or biphasic actions. Hahnemann himself explained that homeopathy worked through a dematerialised spiritual force.

We also hear things like a thousand people were given this medicine and then 95% did not get the disease, so it works. This is not what a trial is and these experiments are worthless unless compared with 1,000 people who are given placebos (i.e. blank doses).

The fact that homeopathy thrives is not proof of its efficacy just like the existence of tarot readers and astrologers does not prove that these practices have any scientific basis.

Homeopathy puts on an aura of respectability thanks to scientific journals from major publishers that cater to it.

Many reputed institutions have looked at the available literature and their conclusions are unequivocal. The US National Institutes of Health say, Theres little evidence to support homeopathy as an effective treatment for any specific health condition. The UKs National Health Services (NHS) state, Theres been extensive investigation of the effectiveness of homeopathy. Theres no good-quality evidence that homeopathy is effective as a treatment for any health condition.

A report prepared by a committee appointed by the UK parliament in 2010 called the British governments position on homeopathy confused and recommended that the government stop funding homeopathy on the NHS. The report argued that homeopathy undermines the relationship between NHS doctors and their patients, reduces real patient choice and puts patients health at risk. Since 2017, the NHS has severely restricted access to homeopathy.

After an extensive literature survey, Australias National Health and Medical Research Council concluded in 2015 that there was no reliable evidence from research in humans that homeopathy was effective for treating the range of health conditions considered: no good-quality, well-designed studies with enough participants for a meaningful result reported either that homeopathy caused greater health improvements than placebo, or caused health improvements equal to those of another treatment.

A false shield

A much-quoted statement by the WHO sometimes distorted during the Ebola outbreak in 2014 said, In the particular context of the current Ebola outbreak in West Africa, it is ethically acceptable to offer unproven interventions that have shown promising results in the laboratory and in animal models but have not yet been evaluated for safety and efficacy in humans as potential treatment or prevention (emphasis added). However, the words in bold are often omitted in public statements, such as in the AYUSH ministry advisory.

All the hype and publicity surrounding Aa30C have set the stage for people to desperately chase what they think is a wonder drug. Clarifications of the type issued by the AYUSH ministry, stating that their recommendation is only in the general context or that it is only for add-on preventive care, is like water off a ducks back. Panic-buying of Aa30C has already been reported. News of random, untracked distributions by various agencies and buyers flocking to pharmacies to buy the concoction at inflated prices continue to pour in.

The problem is significant because people are likely to believe that by imbibing this medicine, they have just acquired a shield against the COVID-19. A corporator in Mumbai mentioned that some people, when questioned about their being out during a lockdown, said that they had taken Arsenicum album. They believed that they would now be immune to the disease.

Monsoon meals: Heres how to stay healthy with right foods for the season – YourStory

You might love the rains or hate the rainy season. Either way, the monsoon brings with it some dramatic changes to your physiology. If you know how to tweak your diet and lifestyle to cope with these external changes in the season, you can do a lot to support your body.

What matters is understanding the changes and learning to go with them. You need to remember that you always have to eat differently and live differently whenever the seasons change, in order for your body to move harmoniously through them.

The biggest impact to your body during the monsoon is that your digestion will not be the same. This thought needs to be at the root of all change.

This means that you need to change what you eat, so that you eat food that is easier to digest, both in terms of the food itself and in the method of preparation. You don't need to add any superfoods. I believe that superfoods only become superfoods when they are used in the right manner at the right time.

Begin your day with hot beverages and a warm breakfast during the monsoon

Now that you know these two things that you have to keep in mind about the monsoons, I want to actually explain how you can apply this to your diet and lifestyle.

Exercise is very important during the monsoon

Poha is both delicious and healthy for the rainy season

A good digestive tea can boost your immunity during the monsoon

Boil some ginger, a tablespoon each of coriander seeds, cumin seeds, fennel seeds and fenugreek seeds in two cups of water. Reduce the quantity to one cup. Strain and consume with your meal.

This is a simple tea which makes a world of difference to your digestion in the monsoon. Since your digestion is at the root of immunity, improving your digestion is the best way to support your health and prevent an infection this monsoon!

Painstakingly handwritten chart preserves complicated feat of breaking the DNA code

When scientists discovered DNA and its double-helix form, they had finally identified the molecules that contain every human's unique genetic code.

But determining how those instructions were interpreted by cells was a beast of a challenge. Scientists had to figure out how a double helix of just four building blocks could be translated into proteins, the molecules that are the basis of living tissues - and they had to do so without the help of computer spreadsheets.

A painstakingly handwritten chart preserved by the U.S. National Library of Medicine shows how complicated the feat was.

It was filled in by biochemist Marshall W. Nirenberg and his colleagues at the National Institutes of Health. During the 1960s, they raced with other researchers to figure the universal code shared by every living organism's cells.

Proteins consist of linked chains of amino acids, and they are made in two stages. First, the information in a molecule of DNA is transcribed into a messenger RNA (mRNA) molecule that consists of codons. Each codon consists of a three-unit combination of RNA nucleotides U, C, A and G. Cells then use the mRNA's codons as instructions to create chains of amino acids that, taken together, equal proteins. The codons - 64 in all - also tell the cells when to start or stop amino acid chains.

In 1961, Nirenberg and his colleague, J. Heinrich Matthaei, proved that the combination UUU was decoded as the amino acid phenylalanine. Over the next five years, the team conducted more experiments to figure out which codons created which amino.

As they went along, their working chart - made of multiple pieces of taped-together paper - gained a vast collection of letter combinations, stars and circles. Nirenberg shared the 1968 Nobel Prize in physiology or medicine for his work on the code, a discovery that is known as one of the most significant in the history of science.

The Mysterious World Of Viruses And Why You Can’t Escape Them – Outlook India

Albert Szent-Gyorgyi was a giant of twentieth century science. His discoveries on Vitamin C, the Krebs cycle and how our muscles function are part of textbooks of biochemistry. He once wrote how, in his search for a picture of life, the torch-light slipped over the very edge of being: I started with anatomy, then shifted to function, to physiology, and studied rabbits. But then I found rabbits too complicated and shifted to bacteriology...later I found bacteria too complicated and shifted to molecules and began to study chemistry.... I ended with electrons which have no life at allmolecules have no lifeso life ran out between my fingers actually while I was studying it, trying to find it...

Szent-Gyorgyi was not alone in this. The boundary that separates the non-living from the livingthat mysterious cuspis a real one, but trying to put that knife-edge under a microscope can actually impede understanding life on this blue planet. Take the most abundant biological entities of natureviruses. The sheer number and diversity of viruses easily dwarfs humans, our crops and domesticated cattle, the billions of insects teeming in the tropical forests, even the microscopic organisms abundant in any river. A litre of seawater may contain a hundred billion viruses of few thousand different kinds! They occur in millions in the lungs and intestines of healthy people. They are present deep below the Antarctic surface, in the subterranean caves of Mexico, on the scorched sand dunes of African deserts, and in almost every living species scientists have studied. They control the growth of bacterial populations, play vital roles in the mega geochemical cycles that make up our environment and can, of course, evolvejumping from one host species to another, as we now are only too keenly aware. Its no wonder that Carl Zimmer referred to the Earth as a planet of viruses. The present global crisis brought on by Covid-19directly linked to rampant deforestation and illegal animal tradeis a result of our unbridled and greedy misadventures into virosphere.

Yet, viruses are not exactly alive in the sense cellular organisms are. The latter are made up of one or many cells. Indeed, many of them, like ourselves, form large, organised cellular associationsa body. The bodies move, eat, fight, take in resources to build their cells and, in time, mate with other bodies to make more cellular entities like themselvesthe next generation. The instructions for doing all this is encoded in a long chain-like polymer(s), called DNA, present within the cells. The DNA is a manual, a blueprint; different links in the chaingenescarry the information for making different proteins. Following those commands embedded in the DNA, the rest of the cell makes proteins. In turn, the proteins (like insulin, antibodies, enzymes and collagen) join hands to do all the physiological work, finally leading to reproduction and thus ensuring that there are more copies of that body and the DNA within. Its teamwork between the cells DNA and protein-making apparatus.

Viruses do the same but they have found a shortcut. They do carry DNA (or RNA, a related molecule), but, being so tiny, theres no space for the protein-making apparatus. Theres no need either: when a virus infects a cell, it hijacks the latters protein-producing factories, captures the depots of nutrients and commands the cell to make only multiple copies of viral proteins and viral DNA! Thus, although they carry only a part of the ingredients essential for life, viruses are intracellular parasites that evolve and flourish in the foggy zone that demarcates the living from the inanimate.

Also Read | Did The Lockdown Work? What Did It Do? Would Have Happened Without It?

How viruses evolved this hijack strategy is an enduring mystery. The fact that prehistoric viruses have not left fossils has not helped either. But today, theres a wealth of knowledge that take us to the very origins of life. Notably, even within present-day cells, some RNA molecules can store genetic information (like DNA does) as well as catalyse biochemical reactions (like proteins do). This is an indicator that at the very dawn of life, in the hot, anoxic oceans of the primordial world, simple chemicals formed bonds resulting in complex molecules and some of them, in turn, gained the chemical ability to make copies of themselves. It was certainly not an efficient process, more like a stenographer who makes mistakes while typing several copies of a document, so soon there were variants of the parent molecule that were competing with each other for better duplication. In time, small RNAs (or the more stable DNAs) might have joined to form larger chains of genes, and then a membrane of fats probably enclosed them to form a mobile, self-replicating unit. Alternatively, some proto-cells might have gained both DNA and protein-making machines, but then lost the latter and learnt to enslave neighbours who had both. Probably both mechanisms gave rise to the vast repertoire that makes up virosphere today. Evolution by natural selection had found its way.

What is certain is that its this ancient lineage that has made viruses so ubiquitous. Animals, plants and bacteriaall are hosts to viruses in this timeless struggle for existence. The most abundant of viruses are the bacteriophages, literally the bacteria-eaters. But, phages do not only devour bacteria. They constantly shuttle fragments of bacterial DNA from one cell to another, creating fresh combinations of genes and thus providing fodder for evolution. Science has put these phage-couriers to good use. During WWI, Felix dHerelle discovered that bacteriophages could be used to cure soldiers of dysentery. Popular in the 1930s, phage therapy lost to non-living antibiotics. However today, when antibiotic-resistant bacteria have significantly blunted our ability to stop infections, phage therapy is being studied with renewed enthusiasm. In addition, oncolytic viruses are being harnessed to selectively target and kill cancer cells. Thus, no more only parasites, viruses now answer to that proverban enemys enemy is a friend! The utility of viruses does not stop there. Rather, their perennial arms-race with bacterial cells is the source of what are called restriction enzymes and CRISPR-Cas, sets of bacterial proteins without which many of the applications of modern biotechnology would be impossible.

There are others who are less friendly, of coursefor example, the malignancy-inducing Papillomavirus and Hepatitis B viruses. But, humankinds association with viruses goes way beyond diseases and modern technology. Stunning as it may seem, the DNA in our chromosomes is peppered with sequences that once belonged to active viruses. Called Endogeneous Retroviruses, these relics of past encounters make up more than 8 per cent of our genomic spacea colossal number when you consider that our protein-encoding sequences take up hardly 1.5 per cent! None of them make active viruses any more, but some have been recruited into our cellular circuits. One noteworthy retrogene is Arc, which is essential for long-term memory storage in the human brain. Another is Syncytin. Originally from an endogeneous retrovirus, it has got harnessed to build up the placentaa unique mammalian organ without which none of us would have been born! These new findings, however, should not confound us. After all, the present is a fleeting snapshot on the evolutionary timescale and, like viruses, we are little more than carriers and mixers of genetic information. The restculture, history, societies, politicsare facets of human collective imagination.

U-M researchers identify new approach to turning on the heat in energy-burning fat cells – University of Michigan News

Heat map of thermogenic fat cells (artistic rendering). Image credit: Life Sciences Institute multimedia designer Rajani Arora

Researchers have discovered a new set of signals that cells send and receive to prompt one type of fat cell to convert fat into heat. The signaling pathway, discovered in mice, has potential implications for activating this same type of thermogenic fat in humans.

Thermogenic fat cells, also called beige fat or beige adipocytes, have gained attention in recent years for their potential to curb obesity and other metabolic disorders, due to their ability to burn energy stored as fat. But scientists have yet to translate this potential into effective therapies.

The challenge of activating beige fat in humans arises, in part, because this process is regulated through so-called adrenergic signaling, which uses the hormone catecholamine to instruct beige fat cells to start burning energy. But adrenergic signaling also controls other important biological functions, including blood pressure and heartbeat regulation, so activating it in humans with agonists has potentially dangerous side effects.

In a new study scheduled for online publication June 12 in the journal Developmental Cell, a team of researchers led by the University of Michigan Life Sciences Institute describes a pathway that can regulate beige fat thermogenesis independently of adrenergic signaling. Instead, it operates through a receptor protein called CHRNA2, short for Cholinergic Receptor Nicotinic Alpha 2 Subunit.

This pathway opens a whole new direction for approaching metabolic disorders, said Jun Wu, an assistant professor at the LSI and the studys senior author. Of course, this cholinergic pathway also is involved in other important functions, so there is still much work to do to really figure out how this might work in humans. But we are encouraged by these initial findings.

For their study, Wu and her colleagues blocked the CHRNA2 pathway only in adipocytes in mice, and then fed the mice a high-fat diet. Without the CHRNA2 receptor proteins, the mice showed greater weight gain than normal mice, and were less able to activate thermogenesis in response to excess food intake.

Wu believes the findings are particularly exciting in light of another research teams recent discovery of a new type of beige fat that is not regulated by catecholamine. This newest study from the LSI indicates that this subpopulation of beige fat, called glycolytic beige fat (or g-beige fat), can be activated through the CHRNA2 pathway.

Many patients with metabolic disorders have catecholamine resistance, meaning their cells do not detect or respond to catecholamine, said Wu, who is also an assistant professor of molecular and integrative physiology at the U-M Medical School.

So even if it could be done safely, activating that adrenergic pathway would not be an effective treatment option for such patients. This new pathway, with this new subtype of beige fat, could be the beginning of a whole new chapter for approaching this challenge.

The research was supported by the National Institutes of Health, American Diabetes Association, Chinese Scholarship Council and Michigan Life Sciences Fellows program.

Study authors are: Heejin Jun, Shanshan Liu, Jine Wang, Alexander Knights, Margot Emont, X.Z. Shawn Xu and Jun Wu of U-M; Yingxu Ma of U-M and Central South University, China; Yong Chen and Shingo Kajimura of the University of California, San Francisco; Jianke Gong of U-M and the Huazhong University of Science and Technology; and Xiaona Qiao of U-M and Fudan University, China.

Soccer turns to Electronic Caregiver for health app – Las Cruces Bulletin

From an Electronic Caregiver news release

As COVID-19 regulations ease, Las Cruces-based health technology company Electronic Caregiver (ECG) has developed a digital application to help professional soccer players in Austria resume training and competition as safely as possible.

ECG was subcontracted by Paracelsus Medical University (PMU) in Salzburg, Austria to build a data collection interface and mobile app, called Wallpass, to identify and track COVID-19 exposure risk among players of the Austrian Soccer Bundesliga, the highest-ranking national league club competition in Austrian soccer.

ECG and PMU will collaborate with the University of Salzburg and the Red Bull Athlete Performance Center (APC) in Salzburg to help maintain overall athlete and staff members health.

This project, coupled with other initiatives that ECG is working on right now, is targeted toward helping the world get back to some semblance of normalcy and will allow people to begin living their lives again, said ECG Chief Technology Officer David Keeley. By providing this technology, were helping to be a driving force for job creation or re-establishment. Were helping communities heal as it relates to getting back to normal, and were doing so in a way that maximizes protection as much as possible.

Apple Inc. recently approved ECGs digital app for testing. Professional soccer players participating in the study to evaluate the efficacy of the app will register and download the app so that it can begin collecting data on physiology, standard training and competition, recovery and COVID-19 or infectious disease exposure risk (including survey question responses and geopositioning). PMUs research team and medical staff will review the data and quantify the safeness of returning to play.

Were trying to show that the risk of returning to play is minimal with enhanced safety procedures, Keeley said. Teams will be using the app for about three months, and then hopefully, we meet with success, and we can extend and expand through the entire league for the 2021 season.

The results of this study will provide new and much-needed data on the prevalence, nature and behavior of COVID-19-related illness in professional athletics.

From a medical perspective, it is very important to gain and analyze data regarding risk factors and prevention approaches against COVID-19 in professional sports to get a better understanding and improve safety as best as possible for team sport athletes, said PMU Institute of General, Family, and Preventive Medicine Head professor Maria Flamm.

It is of greatest importance to guarantee a safe sport and to understand the possible mechanisms and consequences of the COVID-19 pandemic or future diseases, said APCs head of research and development/science Thomas Stoeggl, professor for training science at the University of Salzburg.

Along with professional athletes, this project and ECGs mobile app will pave the way for other organizations and individuals to return to daily life.

I could see this technology used in schools; I could see it used in places of business; I could see it used for organizations that want to host large gatherings, Keeley said. I see its applicability across a wide range of scenarios and use cases.

UCI Researchers Uncover Cancer Cell Vulnerabilities; May Lead to Better Cancer Therapies – Newswise

Newswise Irvine, CA June 12, 2020 A new University of California, Irvine-led study reveals a protein responsible for genetic changes resulting in a variety of cancers, may also be the key to more effective, targeted cancer therapy.

The study, published today in Nature Communications, titled, Quantification of ongoing APOBEC3A activity in tumor cells by monitoring RNA editing at hotspots, reveals how the genomic instability induced by the protein APOBEC3A offers a previously unknown vulnerability in cancer cells.

Each day, in human cells, tens of thousands of DNA damage events occur. In cancer cells, the expression of the protein APOBEC3A is one of the most common sources of DNA damage and mutations. While the mutations caused by these particular proteins in cancer cells contribute to tumor evolution, they also cause breaks in the DNA, which offer a vulnerability.

Targeting cancer cells with high levels of APOBEC3A protein activities and disrupting, at the same time, the DNA damage response necessary to repair damages caused by APOBEC3A, could be key to more effective cancer therapies, said Remi Buisson, PhD, senior investigator and an assistant professor in the Department of Biological Chemistry at the UCI School of Medicine. However, to exploit the vulnerability of the cancer cells, it is critical to first quantitatively measure the proteins activity in tumors.

To understand the role of APOBEC3A in tumor evolution and to target the APOBEC3A -induced vulnerabilities, the researchers developed an assay to measure the RNA-editing activity of APOBEC3A in cancer cells. Because APOBEC3A is difficult to quantify in tumors, developing a highly sensitive assay for measuring activity was critical. Using hotspot RNA mutations, identified from APOBEC3A-positive tumors, the team developed an assay using droplet digital PCR and demonstrated its applicability to clinical samples from cancer patients.

Our study presents a new strategy to follow the dysregulation of APOBEC3A in tumors, providing opportunities to investigate the role of APOBEC3A in tumor evolution and to target the APOBEC3A-induced vulnerability in therapy, said Buisson. We anticipate that the RNA mutation-based APOBEC3A assay will significantly advance our understanding of the function of the protein in tumorigenesis and allow us to more effectively exploit the vulnerabilities it creates in cancer therapy.

This study was funded in part by the National Institutes of Health, a California Breast Cancer Research Program grant and an MPN Research Foundation Challenge grant.

EHA25Virtual: Adult Patients With Sickle Cell Disease May Be at Increased Risk of Adverse Outcomes From COVID-19 – P&T Community

THE HAGUE, Netherlands, June 13, 2020 /PRNewswire/ -- Sickle cell disease (SCD) and thalassemia are severe inherited blood disorders, often referred to as "hemoglobinopathies." They predominantly affect the Black and Asian ethnic minority populations in England. To ensure good standards and equitable access to care, the National Health Service in England has recently commissioned a model of regional care networks overseen by a new body, the National Haemoglobinopathy Panel. This organizational structure has enabled a rapid response to the COVID-19 epidemic and enabled collection of national data on new cases and outcomes to determine if hemoglobinopathy patients are at risk of adverse COVID-19 outcomes.

We present an analysis on data collected up to June 5th indicating that the majority of cases have been mild, and in particular children do not appear to be at increased risk. However, the data suggests that adults with SCD may be more vulnerable to adverse outcomes. Therefore, we recommend that isolation precautions should be lifted cautiously, and that new therapies and vaccination for COVID-19, when available, should be prioritized for this patient group.
