Skeletal muscles combust both lipids and carbohydrates during exercise. The carbohydrates consist of both glycogen stored in the muscles as well as glucose extracted from the blood. Being a major sink for glucose disposal, skeletal muscle represents an important model tissue for studying the intracellular signaling pathways leading to increased glucose transport.

GALVESTON, Texas — University of Texas Medical Branch at Galveston researchers believe they've found a way to use widely available blood pressure drugs to fight the muscular weakness that normally accompanies aging.
The discovery draws on research linking the loss of muscle mass with age-related changes in the behavior of the hair-thin blood vessels, or capillaries, which supply muscles with the amino acids they need for growth.
NEW YORK (August 20, 2010) -- Casual smokers may think that smoking a few cigarettes a week is "no big deal." But according to new research from physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center, having an infrequent smoke, or being exposed to secondhand smoke, may be doing more harm than people may think. The findings may further support public smoking bans, say the authors.
A medical researcher at the University of Leicester has made a significant advance in the treatment of cervical cancer.
Dr Paul Symonds from the Department of Cancer Studies and Molecular Medicine has demonstrated that the use of a particular drug in collaboration with radiotherapy gives significantly better results than radiotherapy alone.
Eating more green leafy vegetables can significantly reduce the risk of developing type 2 diabetes, finds research published today on bmj.com.
The authors, led by Patrice Carter at the University of Leicester, say there is a need for further investigation into the potential benefits of green leafy vegetables.
In the last two decades there has been a dramatic increase in the number of individuals developing type 2 diabetes worldwide.
Fear of falling is likely to lead to future falls among older people, irrespective of their actual fall risk, finds a study published on bmj.com today.
This indicates that measures of both actual and perceived fall risk should be included in fall risk assessments to help tailor interventions for preventing falls in older people, say the authors.
The virus that causes AIDS may undergo changes in the genital tract rendering HIV-1 in semen different than HIV-1 in the blood, according to researchers from the University of North Carolina at Chapel Hill, the Edward Jenner Institute for Vaccine Research (United Kingdom), and the Baylor Pediatric Center of Excellence (Malawi). The research, published August 19 in the open-access journal PLoS Pathogens, advances understanding of HIV-1 replication in the male genital tract.
CHAPEL HILL – The virus that causes AIDS may undergo changes in the genital tract that make HIV-1 in semen different than what it is in the blood, according to a study led by researchers from the University of North Carolina at Chapel Hill.
A drug to treat inflammation plays a surprising role reducing the level of infection caused by an opportunistic bug that is deadly for AIDS and cancer patients and others with weakened immune systems.
The drug, sulfasalazine, spurs the body to get rid of the fungal evaders by enhancing the body's ability to chew them up instead of leaving the debris to litter the lungs, where it would continue to provoke an onslaught of harmful inflammation.
If you have high blood pressure, binge drinking may dramatically raise your risk of stroke or heart-related death, according to a South Korean study reported in Stroke: Journal of the American Heart Association.
Compared to non-drinkers with normal blood pressure, researchers found that the risk of cardiovascular death in men with blood pressure of at least 168 /100 millimeters of mercury was:
The brothers of men with prostate cancer are at an increased risk of prostate cancer diagnosis because of increased diagnostic activity and not necessarily because they carry a genetic mutation that increases risk of the disease, according to a study published online August 19 in The Journal of the National Cancer Institute.
Want a slimmer, healthier community? Try building more sidewalks, crosswalks and bike paths.
A study authored by Professor David Bassett Jr. from the Department of Kinesiology, Recreation and Sport Studies at the University of Tennessee, Knoxville, and three other researchers was published today in the American Journal of Public Health, concluding that communities with more walkers and cyclists are healthier than those where people must rely on cars to get around.
WASHINGTON (19 August 2010) -- Five engineering breakthroughs, from restoring a degree of eyesight to developinng a new treatment for sudden cardiac arrest, were cited today by IEEE-USA, the U.S. career and public policy unit of the IEEE, the world's largest professional association for the advancement of technology.
The five breakthroughs, as included in television news reports recently distributed to 83 subscribing U.S. television stations, are:
CHAPEL HILL – Researchers at the University of North Carolina at Chapel Hill School of Medicine have uncovered the genetic architecture controlling the growth of the collateral circulation – the "back-up" blood vessels that can provide oxygen to starved tissues in the event of a heart attack or stroke.
Scientists have determined that Helicobacter pylori, the bacterium that causes peptic ulcers and some forms of stomach cancer, requires the vitamin B6 to establish and maintain chronic infection, according to research published this week in the online journal mBio™. This finding, along with the identification of the enzyme the microbe requires to utilize the vitamin, could lead to the development of an entirely new class of antibiotics.
