Does a peptide affect the heart's response to social isolation?

...ossible increased risk of heart disease (including elevated resting heart rate, reduced heart rate variability, and reduced parasympathetic regulation of the heart). This study examines whether oxytocin plays a role in the heart’s detrimental responses to social isolation. The Study: Summary of Metho...

Blocking immune cell action increases Alzheimer's-associated protein deposits

...okines, proteins that attract immune cells and are elevated in brains affected by Alzheimer's, the receptor could be important for the movement of microglia to the site of amyloid-beta deposits. To test that possibility, the investigators used a mouse model of Alzheimer's disease and generated strains in whi...

Protein may hold key to decreasing organ dysfunction rates in heart transplants

... was genetically disabled. The study also found elevated levels of Lcn-2 in the kidneys of mice that had undergone heart transplants, suggesting the protein's possible involvement in the systemic response to IR. "The major goal of our research activities is therefore to understand the exact mechanisms of t...

Killing the messenger RNA -- But which one?

...rential has physiological consequences seen in the elevated uric acid levels." Given the fact that the PRPS1 gene was randomly selected for investigation by the researchers, the findings suggest that a number of other as-yet unidentified disorders may also have their roots in this newly identified microRNA...

Organic is healthier: Kiwis prove that green is good

...ntial benefits of antioxidants and other compounds elevated in organic farm produce. Carl Winter, director of the FoodSafe Program at UC Davies, asks whether these increases in nutrients and antioxidants are of any appreciable health perspective. He is also concerned about any unknown negative effects on the ...

New hereditary breast cancer gene discovered

...ve now found that women with this syndrome have an elevated risk of contracting breast cancer. Saethre-Chotzen is a syndrome that primarily involves malformations of the skull, face, hands, and feet. The syndrome is caused by mutations in a gene called TWIST1. "Our findings show that women with this syndr...

Salamanders suffer delayed effects of common herbicide

...d. While the mechanism by which atrazine causes elevated mortality remains unclear, Rohr says other scientists have evidence suggesting that this pesticide is an endocrine disruptor. Such chemicals disrupt the production of hormones that are vital to normal bodily functions. Concentrations of atrazine ...

Lead-'scrubbing' drug may also improve muscle function in lead-exposed children

Scientists perform 'tricky' operation

...e the sequencing of the genome project has largely elevated awareness of T. vaginalis among researchers, public awareness remains low, especially in developing countries where it has the most impact. "This is a problem as infection with T. vaginalis increases the transmission and acquisition of many other ...

Gene chips forecast ecological impacts of climate change

...?ocean acidification. As a consequence of the elevated levels of the greenhouse gas, carbon dioxide, the predictions for ocean acidification are more problematic than temperature stress alone. Data presented will show how gene chips and other molecular approaches can assist in understanding how marine in...

Napoleon's mysterious death unmasked, UT Southwestern researcher says

...oleon's father died of stomach cancer. In 1961, an elevated level of arsenic was found in hair taken from Napoleon, inspiring rumors of arsenic poisoning. To find answers, Dr. Genta and the other researchers combined current medical knowledge and autopsy reports, memoirs of the physicians who treated Napol...

Molecular signature may identify cisplatin-sensitive breast tumors

...rcent of tumors, some with hormone receptors, have elevated levels of a growth-promoting protein called HER2, and those tumors are candidates for treatment with the monoclonal antibody Herceptin. The third major subtype is the 15 to 20 percent of breast tumors that have neither estrogen nor progesterone rece...
