Binge drinking, an activity that many young people engage in, has associated adverse health risks and we need to do a better job of controlling overall alcohol usage, states an editorial in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj110029.pdf.

In three papers in the January and February issues of the Journal of General Physiology (JGP), Don Hilgemann and colleagues have extensively characterized a previously unidentified process by which up to 75% of the cell plasma membrane can be reversibly endocytosed. This massive endocytosis ("MEND") can be elicited in a variety of cell types with a range of different experimental manipulations, including internal calcium transients in the presence of ATP, membrane treatment with sphingomyelinase, and introduction of various amphiphiles into the membrane bilayer.
STANFORD, Calif. – Researchers at the Stanford University School of Medicine, in collaboration with BioParadox, Inc., have published data supporting the use of platelet-rich plasma as a promising biologic treatment for myocardial infarction (heart attack).
The findings were published online in Cardiovascular Revascularization Medicine and will be presented at The Sixth International Conference on Cell Therapy for Cardiovascular Disease at Columbia University Medical Center, New York City, on January 20, 2011.
The United Nations declared 2010 to be the International Year of Biodiversity and invited the world to take action to safeguard the variety of life on earth. Unfortunately, though, it is seldom completely clear what should be safeguarded. An example is provided by the cheetah, which conventional wisdom tells us does not vary much throughout its wide (if shrinking) range.
Wetter, cooler summers can have a detrimental effect on the milk we drink, according to new research published by Newcastle University.
Researchers found milk collected during a particularly poor UK summer and the following winter had significantly higher saturated fat content and far less beneficial fatty acids than in a more 'normal' year.
Does eating a big breakfast help weight loss or is it better to skip breakfast altogether? Available information is confusing but new research published in BioMed Central's open access journal Nutrition Journal clears a path through these apparently contradictory reports.
Dr Volker Schusdziarra, from the Else-Kröner-Fresenius Center of Nutritional Medicine, conducted a study on over 300 people who were asked to keep a journal of what they usually ate. Within the group sometimes people ate a big breakfast, sometimes small, and sometimes skipped it all together.
A pill containing a mix of essential oils has been shown to significantly reduce the symptoms of premenstrual syndrome (PMS). Researchers writing in BioMed Central's open access journal Reproductive Health tested the tablets by carrying out a randomised, controlled trial in 120 women.
DETROIT - Shoulder motion after rotator cuff surgery remains significantly different when compared to the patient's opposite shoulder, according to a Henry Ford Hospital study.
In a study that updated prior findings, researchers used X-rays providing a 3D view of motion of the arm bone in relation to the shoulder blade, to compared motion in the shoulders of 22 patients who had arthroscopic surgical repair of tendon tears and no symptoms in their other shoulders. An earlier study looked at 14 patients.
January 16, 2011 – (BRONX, NY) – In a technique that could eventually shed light on how gene expression influences human disease, scientists at Albert Einstein College of Medicine of Yeshiva University have for the first time ever successfully visualized single molecules of naturally-occurring messenger RNA (mRNA) transcribed in living mammalian cells. The scientific achievement is detailed in the January 16 online edition of Nature Methods.
Scientists have identified a protein that acts as a "master switch" in certain white blood cells, determining whether they promote or inhibit inflammation. The study, published in the journal Nature Immunology, could help researchers look for new treatments for diseases such as rheumatoid arthritis that involve excessive inflammation.
HOUSTON – A small slice of RNA inhibits prostate cancer metastasis by suppressing a surface protein commonly found on prostate cancer stem cells. A research team led by scientists at The University of Texas MD Anderson Cancer Center reported today in an advance online publication at Nature Medicine.
WASHINGTON, Jan. 15, 2011 — In research described as "a stark warning" to those tempted to start smoking, scientists are reporting that cigarette smoke begins to cause genetic damage within minutes — not years — after inhalation into the lungs.
Their report, the first human study to detail the way certain substances in tobacco cause DNA damage linked to cancer, appears in Chemical Research in Toxicology, one of 38 peer-reviewed scientific journals published by the American Chemical Society.
Rice bred to perform well in the toughest conditions where the poorest farmers grow rice is a step away from reaching farmers thanks to a major project led by the Chinese Academy of Agricultural Sciences and the International Rice Research Institute (IRRI).
An 18-year study of Kenya's coral reefs by the Wildlife Conservation Society and the University of California at Santa Cruz has found that overfished reef systems have more sea urchins—organisms that in turn eat coral algae that build tropical reef systems.
