Probiotic-derived treatment offers new hope for premature babies

13/02/2013 | CIENCIA ON LINE
"Good" bacteria that live in our intestines have been linked with a variety of health benefits, from fighting disease to preventing obesity. In a new study medical researchers have discovered another advantage to these friendly microscopic tenants: Chemicals secreted by good bacteria that...

Preventing obesity transmission during pregnancy

13/02/2013 | CIENCIA ON LINE
A much neglected part of the obesity epidemic is that it has resulted in more overweight/obese women before and during pregnancy. Their offspring also tend to have higher birth weights and more body fat, and carry an increased risk of obesity and chronic diseases later in life. However, the...

Marsh plants actively engineer their landscape

13/02/2013 | CIENCIA ON LINE
Marsh plants, far from being passive wallflowers, are "secret gardeners" that actively engineer their landscape to increase their species' odds of survival, says a team of scientists from Duke University and the University of Padova in Italy. Fuente :...

Cellular renewal process may underlie benefits of omega fatty acids

13/02/2013 | CIENCIA ON LINE
A search for genes that change their levels of expression in response to nutrient deprivation has uncovered potential clues to the mechanism underlying the health benefits of omega fatty acids. Massachusetts General Hospital researchers report finding that feeding omega-6 fatty acids to C. elegans...

13/02/2013 | CIENCIA ON LINE
New Vanderbilt-led research published in the Feb. 14 issue of the New England Journal of Medicine has identified the relatively unknown human metapneumovirus (MPV) as the second most common cause of severe bronchiolitis in young children. Fuente :...

Rewiring the serotonin system

13/02/2013 | CIENCIA ON LINE
An interdisciplinary team of researchers from the University of Texas Medical Branch at Galveston and the University of Houston has found a new way to influence the vital serotonin signaling system -- possibly leading to more effective medications with fewer side effects. Fuente :...

Light-emitting bioprobe fits in a single cell

13/02/2013 | CIENCIA ON LINE
Stanford study is the first to demonstrate that sophisticated, engineered light resonators can be inserted inside cells without damaging the host. The researchers say it marks a new age in which tiny lasers and light-emitting diodes yield new avenues in the study and influence of living cells....

Recent marijuana use in HIV-infected Russians associated with increased sex and drug risk behaviors

13/02/2013 | CIENCIA ON LINE
Researchers from Boston Medical Center and Boston University's School of Medicine and School of Public Health have found that in Russian HIV-infected risky drinkers, marijuana use is associated with other increased risky behaviors involving drug use and sex. These findings, published online in the...

Team creates MRI for the nanoscale

13/02/2013 | CIENCIA ON LINE
An international team of researchers including CCNY and the University of Stuttgart have opened the door for MRI technology at the nanoscale. Using tiny defects in diamonds they sensed the magnetic resonance of molecules to peer down to the level of atoms. Fuente :...

Gene associated with high anxiety can have protective effect on the battlefield

13/02/2013 | CIENCIA ON LINE
Tel Aviv University's Prof. Yair Bar-Haim reports that susceptibility to post-traumatic stress disorder can be identified through a combination of genetic and psychological testing. Through training, soldiers can learn to reduce their risk for PTSD, and testing could prove valuable in PTSD...

Stem cell source an important factor, impacting ability to treat myocardial infarction

13/02/2013 | CIENCIA ON LINE
When adipose-derived stem cells (ASCs) and bone marrow-derived stem cells (BMSCs) obtained from a single 84 year-old male donor with ischemic coronary disease were transplanted to treat myocardial infarction in a rat model, researchers found that the ASCs preserved more cardiac function in the test...

Impact of stem cell transplantation location in brain a crucial factor for cell survival

13/02/2013 | CIENCIA ON LINE
Researchers found that nonself-donated cells better survive implantation into brains of immunocompetent research mice when grafts are injected into the striatum (STR) of the brain rather than injected into the forceps minor (FM) region. All FM grafts were rejected; STR grafts accumulated and...

Drug shown to reverse radioiodine resistance in some advanced thyroid cancers

13/02/2013 | CIENCIA ON LINE
Memorial Sloan-Kettering Cancer Center researchers have found that the investigational drug selumetinib shuts down the signaling of genetic mutations that prevent some patients' thyroid cancer tumors from absorbing radioiodine, the most effective treatment for the disease. Fuente :...
