Replace your coffee with green tea

Most people would never think of putting green tea in the performance enhancer category. Supposedly the only supplements that belong there are steroids and other anabolic substances. But this is perhaps too restrictive, if not alarming for the average person wanting to become fit and remain that way forever.

Some athletes use green tea. This is primarily an Eastern drink, promoted by Asian practitioners who even go so far to say that it is better to be three days without food than to be one without green tea. That may be shocking to the three meals per day Westerner who never misses that noon time sandwich at least.

Westerners drink coffee. Most of us do a rather good job of limiting our intake to less than a gram daily of caffeine. To say that green tea is superior and contains caffeine raises eyebrows. It's just not American presumably.

The green tea being talked about is the Asian variety, not the English or the American. It has EGCG in it. That is epigallocatechin gallate which produces produces remarkable effects (which are talked about extensively in other articles) on some of the toughest of conditions.

But the focus here is on fitness. What does it do for people and how much does it cost? Of course, one can brew it getting the benefits of five to six cups daily, which go far beyond the great feelings which follow. Or one can simply buy a package of twenty capsules for about five dollars from the local drug store. One of these capsules daily along with thirty to forty minutes of an aerobic activity such as cycling makes a noticeable difference in nearly everyone.

One of the most common response of people who try this is that they are able to go faster longer with less discomfort. This is a considerable help to anyone who knows that the more you pedal or run the more fit you will become. To some that may be counter intuitive as overdoing anything supposedly results in burn out, an alleged irreversible form of exhaustion. Yet training consistently and in moderation does not have this effect.

Green tea enables you to go the distance. Granted, your will power has much to say in this regard. But the green tea, just one capsule daily, makes working out much easier. Is not this what most of us need to insure that we will hang in there for the long haul?

Household Antibacterial Products and Increased Antimicrobial Resistance

Misuse of antibiotics is the leading cause of emerging antimicrobial resistance — a public health crisis in the making. Inappropriate prescribing practices by health care providers contributes greatly to this problem, but now there is evidence that everyday cleaning and hand-washing may also contribute to the growing trend of antimicrobial resistance. Bacteria become resistant to antibiotics or antimicrobial products when they develop a way to keep the antibiotic from working. Bacteria are constantly evolving and, in the presence of inadequate or inappropriate antibiotics, they develop mechanisms to overcome the killing

Scientists Discover Early Key To Regeneration

Science may be one step closer to understanding how a limb can be grown or a spinal cord can be repaired. Scientists at The Forsyth Institute have discovered that some cells have to die for regeneration to occur. This research may provide insight into mechanisms necessary for therapeutic regeneration in humans, potentially addressing tissues that are lost, damaged or non- functional as a result of genetic syndromes, birth defects, cancer, degenerative diseases, accidents, aging and organ failure. Through studies of the frog (Xenopus) tadpole, the Forsyth team examined the cellular underpinnings of regeneration.

The Xenopus tadpole is an ideal model for studying regeneration because it is able to re-grow a fully functioning tail and all of its components, including muscle, vasculature, skin, and spinal cord. The Forsyth scientists studied the role that apoptosis, a process of programmed cell death in multi-cellular organisms, plays in regeneration. The research team, led by Michael Levin, Ph.D., Director of the Forsyth Center for Regenerative and Developmental Biology, found that apoptosis has a novel role in development and a critical role in regeneration. According to Dr. Levin, "Simply put, some cells have to die for regeneration to happen."

The findings will be published in the January 1, 2007 issue of Developmental Biology (v301i1). "We were surprised to see that some cells need to be removed for regeneration to proceed," said Ai-Sun Tseng, Ph.D. the paper's first author. "It is exciting to think that someday this process could be managed to allow medically therapeutic regeneration."

In the context of efforts to understand biophysical controls of regenerative processes, The Forsyth Center for Regenerative and Developmental Biology investigated the dynamics of cell number control in the regenerating tail bud. Previous research in the field has shown that one mechanism by which cell number is controlled is by programmed cell death, which has been shown to be involved in sculpting of growing tissue in a number of developmental systems including heart, limb and craniofacial patterning.

This study shows that despite the massive tissue proliferation required to build the tail, an early apoptotic event is required for regeneration. Normal regeneration of the tail includes a small focus of apoptotic cells; when apoptosis is inhibited during the first 24 hours, regeneration cannot proceed and the growth of nerve axons becomes abnormal. Later inhibition of apoptosis has no effect, suggesting that the programmed death of a specific cellular component is a very early step in the regeneration program. One possible model is that tissues normally contain a population of cells whose purpose is to prevent massive growth in the region surrounding them. Future work by the Levin group will identify the cells that must die, in order to try to understand the signals that cells utilize for growth control.

Michael Levin, PhD. is an Associate Member of the Staff in The Forsyth Institute Department of Cytokine Biology and the Director of the Forsyth Center for Regenerative and Developmental Biology. Through experimental approaches and mathematical modeling, Dr. Levin and his team examine the processes governing large-scale pattern formation and biological information storage during animal embryogenesis. The lab's investigations are directed toward understanding the mechanisms of signaling between cells and tissues that allows a living system to reliably generate and maintain a complex morphology. The Levin team studies these processes in the context of embryonic development and regeneration, with a particular focus on the biophysics of cell behavior.

The Forsyth Institute is the world's leading independent organization dedicated to scientific research and education in oral, craniofacial and related biomedical sciences.
