WASHINGTON, DC (April 28, 2011)––Studies have shown that stress can affect the immune system and weaken the body's defense against infection and disease. In cancer patients this stress can also affect a tumor's ability to grow and spread. However, the biological mechanisms that underlie such associations are not well understood. Now, researchers at Fox Chase Cancer Center find that poor psychosocial functioning is associated with greater vascular endothelial growth factor (VEGF) expression––a signaling protein that not only stimulates tumor growth, but is also associated ...

Potential molecular targets of the anti-HIV drug nelfinavir have been identified, and may explain why the drug is also effective as a cancer therapy. Findings will be published in the open-access journal PLoS Computational Biology on 28th April 2011. Nelfinavir is a protease inhibitor that prevents replication of the HIV virus. It has also been found to have a positive effect on a number of solid tumor types but the mechanism of how the drug worked in humans was unclear. Researchers from the University of California San Diego and the City University of New York (CUNY) ...

Getting vaccinated against the flu lowers kidney transplant recipients' risk of organ loss and death, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). The results suggest that concerns about the safety of the influenza vaccine in transplant recipients are unwarranted. Influenza can cause severe illness and even death in some individuals. Organ transplant recipients and those taking immunosuppressant medications face a particularly high risk of dying after being infected. Protection against the flu ...

The angiotensin-converting enzyme (ACE) inhibitor drug, ramipril, is particularly effective in lowering the risk of end-stage renal disease (ESRD) in obese patients, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). "Obese patients with kidney disease progress more quickly towards renal failure compared to non-obese patients, and ramipril virtually abolishes this excess risk," comments Carmine Zoccali, MD (CNR-IBIM and Ospedali Riuniti di Reggio Calabria, Italy). The researchers analyzed data from a previous ...

MADISON — Researchers eavesdropping on complex signals emanating from a remote Wisconsin lake have detected what they say is an unmistakable warning — a death knell — of the impending collapse of the lake's aquatic ecosystem. The finding, reported today (April 29) in the journal Science by a team of researchers led by Stephen Carpenter, a limnologist at the University of Wisconsin-Madison, is the first experimental evidence that radical change in an ecosystem can be detected in advance, possibly in time to prevent ecological catastrophe. "For a long time, ecologists ...

Being tall and obese may increase your risk for potentially dangerous blood clots, according to new research in Arteriosclerosis, Thrombosis and Vascular Biology: Journal of the American Heart Association. Obesity is a well-known risk factor for clots in deep veins (usually in the legs) and for pulmonary embolism, a clot in blood vessels of the lungs that can result in sudden death or strain on the heart. Together, the two conditions are called venous thromboembolism (VTE). Compared with short (5 feet, 7.7 inches or less) and normal-weight men (body mass index < 25kg/m2), ...

The latest issue of the journal Cell* carries an article that is likely to help solve one of the long-standing mysteries of biomedicine.

Researchers at the University of California, San Diego and Hunter College of the City University of New York (CUNY) have identified potential human molecular targets of the anti-HIV drug Nelfinavir, which may explain why the drug is also effective as a cancer therapy. Their study will be published in the online edition of PLoS Computational Biology on April 28. Nelfinivir is a protease inhibitor that prevents replication of the HIV virus, but it has also been found to have a positive effect on a number of solid tumor types, and is currently in clinical trial as a cancer ...

It's one thing to recognize your childhood home when you see it in a photograph and quite another to accurately describe or draw a picture of it based on your recollection of how it looked. A new report published online on April 28 in Current Biology, a Cell Press publication, offers some of the first clear evidence that monkeys, like humans, have the capacity for both forms of memory. The researchers found that rhesus monkeys can flexibly recall extremely simple shapes from memory, as evidenced by their ability to reproduce those shapes on a computer touch screen. The ...

Our own social status influences the way our brains respond to others of higher or lower rank, according to a new study reported online on April 28 in Current Biology, a Cell Press publication. People of higher subjective socioeconomic status show greater brain activity in response to other high-ranked individuals, while those with lower status have a greater response to other low-status individuals. These differences register in a key component of the brain's value system, a region known as the ventral striatum. "The way we interact with and behave around other people ...

Box jellyfish may seem like rather simple creatures, but in fact their visual system is anything but. They've got no fewer than 24 eyes of four different kinds. Now, researchers reporting online on April 28 in Current Biology, a Cell Press publication, have evidence revealing that four of those eyes always peer up out of the water, regardless of the way the rest of the animal is oriented. What's more, it appears that those eyes allow the jellies to navigate their way around the mangrove swamps in which they live. "It is a surprise that a jellyfish—an animal normally considered ...

For the first time, scientists have been able to paint a detailed chemical picture of how a particular strain of bacteria has evolved to become resistant to antibiotics. The research is a key step toward designing compounds to prevent infections by recently evolved, drug-resistant "superbugs" that often are found in hospitals, as well as in the general population. A paper describing the research, by a team led by Squire Booker, an associate professor in the department of chemistry and the department of biochemistry and molecular biology at Penn State University, will be ...

(Millbrook, N.Y.) By closely monitoring environmental conditions at a remote Wisconsin lake, researchers have found that models used to assess catastrophic changes in economic and medical systems can also predict environmental collapse. Stock market crashes, epileptic seizures, and ecological breakdowns are all preceded by a measurable increase in variance—be it fluctuations in brain waves, the Dow Jones index, or, in the case of the Wisconsin lake, chlorophyll. In a paper published this week in the journal Science, a team of ecologists is the first to show that by paying ...

A large clinical trial comparing treatments for typhoid has recommended the use of gatifloxacin, a new generation and affordable antibiotic. The results of the trial in Kathmandu, Nepal, funded by the Wellcome Trust and the Li Ka Shing Foundation, are published today in the Lancet Infectious Diseases. Typhoid – also known as 'enteric fever' – is characterised by a high fever and diarrhoea. It is transmitted through the ingestion of food or drink contaminated by the faeces or urine of infected people. It causes an estimated 26 million infections each year and over 200,000 ...

Many older adults may be taking "excessive" doses of drugs for thyroid problems which can lead to an increased risk of fractures, finds a study published on bmj.com today. The study raises concern that treatment targets may need to be modified in the elderly and that regular dose monitoring remains essential even into older age. Levothyroxine is a synthetic form of thyroxine (thyroid hormone) and is widely used to treat an underactive thyroid gland (hypothyroidism). Most hypothyroid patients are diagnosed in early or middle adulthood but, as people age, their thyroxine ...
