GlaxoSmithKline (Sirtris Pharmaceuticals) may have abandoned further research on its SRT501 resveratrol pill, but that hasn’t dampened ongoing research of this red wine molecule.
Researchers in Australia now say there are a “plethora of laboratory investigations which provide evidence for the multi‐faceted properties of resveratrol and suggest that resveratrol may target ageing and obesity-related chronic disease by regulating inflammation and oxidative stress.”
Researchers at the University of Queensland (Australia) say the first in vitro (lab dish) and in vivo (living organisms) scientific evidence has certainly confirmed a role for nutra-pharmacology in health.

Knowledge of Health, Inc. (March 18, 2011) – Researchers at the Eppley Institute for Research in Cancer and Allied Diseases, University of Nebraska Medical Center, now explain how an imbalance in estrogen metabolism leads to improper repair of broken DNA which in turn produces gene mutations that promote breast, prostate and other cancers.
These researchers then go on to identify two natural molecular antidotes, a sulfur compound (N-acetyl cysteine) and a molecule found in red wine (resveratrol), which can completely block the initiation of these cancers. Both of these molecules are widely available as dietary supplements. When used together these antioxidants completely abolished the formation of DNA-adducts (cancer-causing chemicals that are coupled with DNA), which is the initiating step in these cancers.

First-Person Accounts Of Longevinex® Users Parallel Survival Mechanisms First Described By Biologist Felix Z. Meerson MD
The human organism must be endowed with
efficient specialized mechanisms that limit
the reaction to stress and prevent stress damage.
— Felix Z. Meerson MD, 1991
Longevinex® users have begun to provide evidence for an exceptional biological phenomenon first described by Felix Z. Meerson MD. Their accounts of super-human health are provided within the following text of this report.
A great difficulty here is in crafting words that sound believable in describing this extraordinary biological phenomenon over plain advertising hype.

There is a very simple measure for any new potential therapy for enhanced longevity: is it either (a) doing at least as well as calorie restriction in mice when it comes to health and longevity, or (b) achieving important results that calorie restriction cannot show in mice – such as outright rejuvenation. The popular supplement resveratrol fails miserably to achieve significant results in either of these goals after more than five years of experimentation and hundreds of millions of dollars in research funding. This means that it is a dead end, or so close to one as makes no real difference. The only value gained lies in incremental improvements in the understanding of metabolism – which could have been achieved while studying more effective paths to the same end goal.

ResveratrolNews.com – Health news headlines today question whether human growth hormone replacement, used by many Americans to overcome the ravages of aging, is just a misdirection.
It is true that the secretion of human growth hormone diminishes with advancing age. But the just-released results of a 22-year study involving a population of genetically-abnormal individuals in Ecuador who produce low amounts of human growth hormone (GHG) and insulin-like growth factor (IGF) reveals this group exhibit no diabetes, almost no cancer and a very low rate of stroke. Strikingly, the blood serum of these people exhibits a double-protective effect: it protects against oxidative damage and gene mutations and also promotes cellular suicide among highly damaged cells.
Laboratory animals, bred to produce low amounts of these hormones, live on average about 30-40% longer. In human terms, that would thrust human populations toward 100-plus-year life spans. Theoretically, humans who produce an insufficient amount of growth hormones should have what is called a square survival curve where most of life is lived without major illness and then you drop dead, said one of the primary researchers involved in the study.

Erectile dysfunction is a sign of poor circulation and/or high blood sugar which many men depressingly face. Selling at prices up to $18 a pill online, Viagra is the best known pill that induces blood vessels in the penis to widen (dilate) and harden the male organ. Cialis and Levitra are other widely-promoted brands of male potency pills. In the animal laboratory, elevated blood sugar was chemically induced to produce erectile dysfunction and then vardenafil (Levitra) was compared against resveratrol, a widely available herbal supplement that is known to dilate blood vessels in the same manner. Resveratrol was comparable to vardenafil and when both were used there was greater effect. The biggest advantage for resveratrol is that it has many other health benefits.

It was Felix Z. Meerson MD, of the Soviet Academy of Medical Sciences, who in the 1980s began to suggest that the heart could be protected from damage caused from a heart attack by mild amounts of biological stress prior to the event. Dr. Meerson even went so far as to subject animals after a heart attack to low-oxygen (high-altitude) environments which led to complete recovery from heart muscle spasms and a two-fold reduction in scarred tissue.
The most obvious application of cardiac pre-conditioning would be in surgery. The surgical table or immediate post-surgical mortality rate for coronary artery bypass surgery and heart valve surgery is roughly ~3% and 5% respectively.
An effort to pre-condition the heart to withstand temporary mild restriction of oxygenated blood is facilitated by application of tourniquets (blood pressure cuff) to extremities (the thighs) prior to the operating table. This is called remote ischemic preconditioning. It is used successfully prior to bypass and heart valve surgery. So it is not like cardiology is totally ignoring preconditioning.

While it is true that supplemental resveratrol lacks human studies regarding heart health, it appears modern medicine is dragging its feet here. Human studies should have ensued by now. A review at the NIH Clinical Trials website reveals none appear to be even in the planning stages.
The big problem is that the primary end point is cardiac death and there is no ethical way to rapidly test a high-risk group against plain placebo. Almost every adult with heart disease is taking vitamins or medications that may interfere with the results, particularly because resveratrol influences cytochrome P450 liver enzymes and may require dosage adjustment of cardiac drugs in use.(1) Also results are years away and thousands of subjects would have to be tested for a period of up to 5-years to obtain conclusive coronary artery disease mortality data.
It may be easier for modern medicine to retrospectively analyze mortality data among resveratrol pills users like aspirin was first studied than to launch a prospective study. To do that, cardiologists would have to start identifying patients already taking resveratrol pills. But unlike aspirin which generally is provided in two standard doses (81 mg and 325 mg), resveratrol pills come in a wide dosage range (20-1000 mg), making analysis difficult.

A large question looms for longevity seekers. Is there anything short of a calorie-restricted diet that has conclusively been shown to produce longevity? That question can’t be practically answered in humans because a decades-long study would have to be conducted.
For background, a limited-calorie diet, in human terms about one meal a day, has been shown to nearly double the lifespan of most living organisms ranging from fruit flies, roundworms and mice, and there is promising data on monkeys now. But obviously, the Calorie Restriction Society has only a few hundred gaunt-looking members. Food deprivation is not going to be a popular way of living longer.
The pursuit of a molecular mimic of calorie restriction has been fervent. Three molecules have risen to the drawing board stage: rapamycin, an anti-fungal/antibiotic drug; metformin, an anti-diabetic drug; and resveratrol, a red wine molecule.
The idea is to find a small molecule that would enter cellular machinery and tickle the same genes as a calorie-restricted diet.

Chennai, India (January 9, 2011) – While age-related vision loss of catastrophic proportions is predicted in coming decades, rising from 17 million patients today to 55 million by the year 2050, it’s possible this catastrophe could be averted and lost vision even restored using molecular medicine.
These are the words of Stuart Richer, OD, PhD, speaking at the 10th annual meeting and International Conference on Recent Trends in Therapeutic Advancement of Free Radical Science, in Chennai, India today.
Dr. Richer says modern medicine is just beginning to evaluate data from the first cases where conventional medical and surgical efforts to restore lost vision had been exhausted and a molecular medicine approach was employed under compassionate use. Even other nutritional therapies including antioxidants were ineffective. Molecular medicine, where small molecules are utilized that can pass through the blood-retinal barrier and which can influence the genetic machinery inside living cells, appears to be very promising, says Dr. Richer.
