COVID-19: MOLNUPIRAVIR – MERCK’S ANTIVIRAL DRUG

Molnupiravir (MK-4482, EIDD-2801) is an investigational oral antiviral medicine that significantly reduced the risk of hospitalization or death at a planned interim analysis of the Phase 3 MOVe-OUT trial in at risk, non-hospitalized adult patients with mild-to-moderate COVID-19. At the interim analysis, molnupiravir reduced the risk of hospitalization or death by approximately 50%; 7.3% of patients who received molnupiravir were either hospitalized or died through Day 29 following randomization (28/385), compared with 14.1% of placebo-treated patients (53/377); p=0.0012. Through Day 29, no deaths were reported in patients who received molnupiravir, as compared to 8 deaths in patients who received placebo.

DR. C’S MEDICINE CABINET: LITHIUM OROTATE

Lithium’s big claim to medical fame is it’s beneficial effect on manic depressive disorders in approximately 1/3 of the cases. It seems to benefit the manic phase more than the depressive phase, and its effect  on isolated depression is uncertain.

A recent report states that lithium works by increasing CRMP 2, which has an effect on tubulin in nerve cells. This report has not yet been confirmed.

When lithium is effective, it must be given in a dose that is almost toxic. People taking this drug should have lithium levels on a regular basis, and be alert to its numerous side effects, diarrhea, lethargy, and the like. It may also have an adverse effect on thyroid function.

I started taking low doses of lithium orotate a while back because of the touted effects on memory, mitochondrial function, and the like. I thought that our hunter gatherer ancestors probably had some exposure to lithium from the Hot Springs present in many areas, and that maybe lithium was a physiologic necessity.  Sodium and potassium are highly regulated ions in the cell membrane of all cells, I thought, so why should not lithium, a kindred element, have some effect there.

Lithium carbonate is the form that is used for treatment of manic depressive disease, and lithium orotate has not been well studied.
When one starts taking a dietary supplement, it is hard to tell whether or not it has any effect. Our bodies are complicated, and even if something does have an effect, the bodies corrective mechanisms can nullify that effect, or even cause  a reverse effect,

After further thought, I plan to start phasing out my lithium orotate. Maybe once a week would be a reasonable dosage, if at all. With irregular dosages, if I notice that I feel better on a day when I take lithium orotate, I might change my mind.

DR. C’S JOURNAL: STEM CELLS

The ultimate stem cell is the fertilized egg from which we came. This omnipotent stem cell divides countless times, “differentiates”, and forms more and more specialized tissues, and our body is the eventual result. All of our tissues contain some stem cells, which grow increasingly rare as we age.

Regenerative medicine takes advantage of stem cells derived from diverse sources. An embryo, an umbilical  cord, or your bone marrow contains stem cells. Even one of your mature connective tissue cells that has been dedifferentiated, or sent back along the pathway that originated from the single cell from which you came, can be induced to form a stem cell (iSC).

If the stem cell originates from your own tissues, it is  accepted by your body, as one of its own.

I have an wealthy acquaintance whose Parkinson’s disease is being treated by one of his own cells induced to form a dopamine containing neuronal stem cell.

The article posted previously regarding rotator cuff surgery apparently used stem cells to shorten the recovery time.

I have heard about the use of stem cells in heart failure, osteoarthritis, and other joint problems, and I’m sure we will hear about this increasingly as time passes. However, there are hurdles to be overcome, moral, legal and medical. The possibility (small) of induced stem cells to evolve into cancer is one medical hurdle, and if the Stem Sell originates from another individual, immunosuppressive treatment must be used in the recipient to allow the stem cells to work. Also, the use of the other individual’s stem cells may involve some moral, legal and possibly religious objections.

Please refer to the following Mayo clinic article for more information.

HARVARD: ‘NANOBODIES’ EVOLVED FROM SYNTHETIC ANTIBODY FRAGMENTS

A new approach developed by Harvard Medical School researchers uses yeast to rapidly evolve synthetic antibody fragments called nanobodies with the aim to find variants that are effective at binding to selected antigens, including SARS-CoV-2. The antibodies are intended for use in diagnostic tests and disease treatments. Read the full story: https://hms.harvard.edu/news/antibody…SHOW LESS

Cancer: Aging & Tumor Microenvironments

Professor Ashani Weeraratna has been studying the cancer microenvironment in her lab for the past 17 years. Taking into account that the tissues in our bodies change as we age is important when researching cancer biology. She hopes that gaining a better understanding of how the growth of cancer cells is affected by their direct cellular ‘neighbourhood’, especially when we age, could be key to developing better treatments for patients with cancer.

Radiotherapy: ‘What Is Theranostics?’ (Video)

What is Theranostics? Dr. Martin Pomper, Director of the Nuclear Medicine and Molecular Imaging division at Johns Hopkins, describes the mechanisms of a groundbreaking cancer treatment that combines imaging and molecular radiotherapy. With this method, radiopharmaceuticals can specifically target cancer cells while sparing most normal tissues.
