UPTON, NY — A study to be published as the "Paper of the Week" in the Journal of Biological Chemistry this December details how zinc, an element fundamental to cell growth, enters the cell via zinc-specific uptake proteins. The research, conducted at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, is the first to purify this kind of protein and study its role in zinc uptake. Zinc is crucial to the health of all living organisms. At the cellular level, zinc is responsible for cell growth, which in turn affects the health, growth, and reproduction ...

Another conclusion of the report is that the amount of money played is underestimated: on average, a gambler who thinks he has bet 22 euros a month, in reality has bet 40 euros. Regarding on line gambling, the player stands out more as an internaut than as a gambler. "They think that they are browsing the net, going into pages of this type and gambling, believing that they are still browsing. On the other hand, in the case of conventional gambling, if you are going to make a bet on football scores, playing instant lottery, buying a lottery ticket, or taking part in ...

See it for yourself: a new breakthrough in imaging technology using a combination of light and sound will allow health care providers to see microscopic details inside the body. Access to this level of detail potentially eliminates the need for some invasive biopsies, but it also has the potential to help health care providers make diagnoses earlier than ever before—even before symptoms arise. Details describing this advance are published online in the FASEB Journal (http://www.fasebj.org/content/early/2010/11/19/fj.10-171728.abstract). In the online research report, ...

The link between sleeping and obesity is drawn tighter as a new research published online in the FASEB Journal (http://www.fasebj.org/content/early/2010/11/19/fj.10-172080.abstract) study shows that what your mother ate when she was pregnant may make you obese or overweight by altering the function of genes (epigenetic changes) that regulate circadian rhythm. In the report, pregnant primate females consuming a high-fat diet altered the function of fetal genes that regulate circadian rhythm (including appetite and food intake) during development. The offspring also had non-alcoholic ...

EAST LANSING, Mich. — Late-preterm babies – those born between 34 and 36 weeks – are at an increased risk for cognitive and emotional problems, regardless of maternal IQ or demographics, according to new research published by Michigan State University researchers in the current edition of the journal Pediatrics. While late-preterm births (full-term pregnancies last at least 37 weeks) have been associated with such problems before, the study represents one of the most rigorous looks at the issue by accounting for other potential causes, said the study's lead author, Nicole ...

Most patients who take anti-depressants give up their treatment in less than six months, the minimum period recommended for treating severe depression and other derived pathologies. This is the conclusion of a new study carried out by Catalan researchers, which reveals that only 25% continue their treatment for more than 11 months. "Only one in every five patients properly completes their treatment", Catalina Serna, co-author of the study, and an expert at the Jordi Gol Primary Care Research Institute (IDIAP) in Lleida, tells SINC. From 2003 to 2007, researchers from ...

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that eventually destroys most motor neurons, causing muscle weakness and atrophy throughout the body. There is no cure and the current treatment has only a moderate effect on the march of the disease, which typically kills within three to five years. This week in PNAS, a team of Brandeis scientists reports an innovative approach to treating the most common form of familial ALS, commonly known as Lou Gehrig's disease. In the study, researchers studied mutations in the gene that makes a particular ...

Johns Hopkins Children's Center scientists have discovered that high blood levels of a protein commonly found in the central nervous system can predict brain injury and death in critically ill children on a form of life support called extra-corporeal membrane oxygenation or ECMO. ECMO, used to temporarily oxygenate the blood of patients whose heart and lungs are too weak or damaged to do so on their own, is most often used as a last resort because it can increase the risk for brain bleeding, brain swelling, stroke and death in some patients. A detailed report of the ...

HIV infected patients whose treatment is delayed not only become sicker than those treated earlier, but also require tens of thousands of dollars more in care over the first several years of their treatment. "We know that it's important clinically to get people into care early because they will stay healthier and do better over the long run," says Kelly Gebo, M.D., M.P.H., an associate professor of medicine in the Division of Infectious Diseases at the Johns Hopkins University School of Medicine and the study's senior author. "But now we know it's also more costly to ...

You detect an object flying at your head. What do you do? You probably first move out of the way -- and then you try to determine what the object is. Your brain is able to quickly switch from detecting an object moving in your direction to determining what the object is through a phenomenon called adaptation. A new study in the Nov. 21 advance online edition of the journal Nature Neuroscience details the biological basis of this ability for rapid adaptation: neurons located at the beginning of the brain's sensory information pathway that change their level of simultaneous ...

MIAMI – November 22, 2010 – This October more than 60 guides and anglers in the Florida Keys poled across the flats from Biscayne Bay to the Marquesas, assisting in the annual bonefish census. This year's count, held in extremely difficult weather with lowered visibility, was down by 25-percent from an 8-year mean estimate of 316,805 bonefish to a new low of about 240,000 bonefish, according to Professor Jerry Ault, a fisheries scientist with the University of Miami's Rosenstiel School of Marine & Atmospheric Science. "Since 2003 we have conducted an annual bonefish ...

In the future, tiny air vehicles may be able to fly through cracks in concrete to search for earthquake victims, explore a contaminated building or conduct surveillance missions for the military. But today, designing the best flying mechanism for these miniature aerial machines is still a challenging task. Creating micro-scale air vehicles that mimic the flapping of winged insects or birds has become popular, but they typically require a complex combination of pitching and plunging motions to oscillate the flapping wings. To avoid some of the design challenges involved ...

From fad diets to exercise programs, Americans continue to fight the battle of the bulge. Now they'll have help from recent Tel Aviv University research that has developed a new method to look at how fat cells -- which produce the fat in our bodies -- respond to mechanical loads. This might be the key to understanding how to control the amount of fat produced by fat cells, the holy grail of weight loss researchers, says Prof. Amit Gefen of Tel Aviv University's Department of Biomedical Engineering. His research is driven by the theory that fat cells, like bone or muscle ...

Fresh insight into how biological clocks adjust to having less sunlight in the winter could help us better understand the impact of jet lag and shift work. Scientists studying the daily activity cycle in plants – known as circadian rhythms – have discovered a finely tuned process that enables the plant's genes to respond to the times of dawn and dusk each day, as well as the length of daylight in between. This system helps the plant to reset its internal clock every day in response to seasonal changes in daylight, which helps the plant control the timing of key activities ...

Infants are more efficient at digesting and utilizing nutritional components of milk than adults due to a difference in the strains of bacteria that dominate their digestive tracts. Researchers from the University of California, Davis, and Utah State University report on genomic analysis of these strains in the November 2010 issue of the journal Applied and Environmental Microbiology identifying the genes that are most likely responsible for this difference. "Human milk oligosaccharides (HMOs) are the third-largest solid component of milk. Their structural complexity ...

Direct contact and droplets are the primary ways influenza spreads. Under certain conditions, however, aerosol transmission is possible. In a study published in the current issue of Clinical Infectious Diseases, available online (http://www.journals.uchicago.edu/doi/abs/10.1086/656743), the authors examined such an outbreak in their own hospital in Hong Kong. On April 4, 2008, seven inpatients in the hospital's general medical ward developed fever and respiratory symptoms. Ultimately, nine inpatients exhibited influenza-like symptoms and tested positive for influenza ...

BINGHAMTON, NY – Binghamton University researchers recently revived ancient bacteria trapped for thousands of years in water droplets embedded in salt crystals. For decades, geologists have looked at these water droplets — called fluid inclusions — and wondered whether microbes could be extracted from them. Fluid inclusions have been found inside salt crystals ranging in age from thousands to hundreds of millions years old. But there has always been a question about whether the organisms cultured from salt crystals are genuinely ancient material or whether they are ...
