Weather Alert  

"Heat Advisory" ...Heat advisory in effect until 6 PM EDT this evening... The National Weather Service in Upton has issued a heat advisory, which is in effect until 6 PM EDT this evening. * Heat index values...in the mid 90s to around 100 degrees. * Timing...into the early evening. The highest heat index values will occur mainly during the afternoon. * Impacts...the heat and humidity may cause heat stress during outdoor exertion or extended exposure. Extreme heat can cause illness and death among the at-risk population who can not stay cool. Precautionary/preparedness actions... A heat advisory is issued when the combination of heat and humidity is expected to make it feel like it is 95 to 99 degrees for two or more consecutive days, or 100 to 104 degrees for any length of time. To reduce risk during outdoor work, the occupational safety and health administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! In cases of heat stroke call 9 1 1. , "Air Quality Alert" ...Air quality alert in effect from 11 am this morning to 11 PM EDT this evening...

Westchester...Rockland. Air quality levels in outdoor air are predicted to be greater than an air quality index value of 100 for the pollutant of ground level ozone. The air quality index...or aqi...was created as an easy way to correlate levels of different pollutants to one scale. The higher the aqi value...the greater the health concern.

Nobelist James Watson Proposes An Unconventional View of Type 2 Diabetes Causation

Nobel laureate, James D. Watson discovers latest hypothesis on the causation of type 2 diabetes.

Cold Spring Harbor, NY - February 28, 2014 - At 85, Nobel laureate James D. Watson, the co-discoverer of the double-helix structure of DNA, continues to advance intriguing scientific ideas. His latest, a hypothesis on the causation of type 2 diabetes, appears online February 28th in the The Lancet, the prestigious British medical journal.

Watson’s hypothesis, which is featured as The Lancet cover story in the U.S. print edition dated March 1-7, 2014, suggests that diabetes, dementias, cardiovascular disease, and some cancers are linked to a failure to generate sufficient biological oxidants, called reactive oxygen species (ROS). Watson also argues the case for a better understanding of the role of exercise in helping to remedy this deficiency.

“The prevalent view of type 2 diabetes,” Dr. Watson says, “is that an excess of intracellular oxidation causes inflammation, which in turn kills cells in pancreatic tissue.”  Proper function of those cells, it is well understood, is critical for the maintenance of normal blood glucose levels.

Over the last several years Watson has been puzzling out an alternative view, based on facts reported in the peer-reviewed literature of medicine and molecular biology. (He makes clear that he is not a medical doctor, rather a student of science.)  He does not question that pancreatic tissue in people with type 2 diabetes is indeed inflamed. But he does present a novel theory of why. “The fundamental cause, I suggest, is a lack of biological oxidants, not an excess,” he says.

For years, Watson knew, doctors have been telling patients with incipient type 2 diabetes – those with high blood sugar levels -- to exercise, often before putting them on a well-proven glucose-lowering drug regimen such as Metformin. Exercise seemed to Watson the key to the puzzle: what was it about exercise that served to benefit people with high blood sugar?

There were important clues, he speculated, in the chemistry of oxidation and reduction reactions. The body’s cells cannot survive without making both oxidants and antioxidants. “There is a delicate balance” between the two, Watson observes. Physical exercise prompts the body to make large numbers of oxidants – molecules called reactive oxygen species, or ROS. In a cellular organ called the endoplasmic reticulum (ER), one such “species,” the oxidant hydrogen peroxide (H2O2), helps forge chemical bonds (disulfide bonds) which stabilize proteins as they fold.

When there is not enough oxidation in the ER, Watson says, proteins emerge unfolded, and cannot function. This, he proposes, causes the inflammation that harms the pancreas, sometimes causing type 2 diabetes.  Hence, Watson suggests, exercise, which promotes oxidation, plausibly can have a beneficial effect on those with high blood sugar. Such benefit would be lessened if not abolished, he speculates, if such an individual consumed large quantities of antioxidants – just as athletes who take large quantities of antioxidant supplements do not seem to benefit or benefit less from their exertions.

Watson has two take-home messages for his audience. “The first is that we sorely need to take a much more serious and thorough scientific look at the mechanisms through which exercise improves our health.” Watson is planning a scientific meeting at Cold Spring Harbor Laboratory later this year which he hopes will launch a larger scientific effort.

There is a second message. “I am not a physician and I cannot offer advice about how people should treat their diabetes; I am advancing a novel idea about how type 2 diabetes can occur. But I also note that just about every doctor I’ve ever known tells every patient who is capable of doing so to exercise. I think exercise helps us produce healthy, functional proteins. But we really need to have some high quality research to demonstrate this.”

“Hypothesis: Type 2 diabetes as a redox disease” by James D. Watson appears online ahead of print in The Lancet on Thursday, February 27, 2014 at 7 pm ET in the U.S.
