A young athlete in seemingly excellent health dies suddenly from a previously undetected cardiovascular condition such as hypertrophic cardiomyopathy in nearly every US state annually. Although these conditions can be detected using electrocardiography (ECG) during a screening exam, the American...

Exposure to environmental endocrine disrupters, such as bisphenol A, which mimic estrogen, is associated with adverse health effects. Bisphenol A is commonly found in plastic bottles and plastic food containers. New research from on the effects of these chemicals on zebrafish shows that embryonic...

In laboratory experiments conducted on human cell lines at the Johns Hopkins Kimmel Cancer Center, scientists have shown that people carrying certain mutations in two hereditary cancer genes, BRCA2 and PALB2, may have a higher than usual susceptibility to DNA damage caused by a byproduct of...

Researchers at Dana-Farber Cancer Institute have developed a tool to help predict how a patient's tumor is likely to behave and which of several possible treatments is most likely to be effective. Fuente : http://www.eurekalert.org/pub_releases/2014-01/dci...

Investigators at Johns Hopkins report they have developed human induced-pluripotent stem cells capable of repairing damaged retinal vascular tissue in mice. The stem cells, derived from human umbilical cord-blood and coaxed into an embryonic-like state, were grown without the conventional use of...

A scientific breakthrough may give the field of radiation oncology new tools to increase the precision and safety of radiation treatment in cancer patients by helping doctors "see" the powerful beams of a linear accelerator as they enter or exit the body. Fuente :...

A team of scientists, led by principal investigator David D. Schlaepfer, Ph.D., a professor in the Department of Reproductive Medicine at the University of California, San Diego School of Medicine, has found that a protein involved in promoting tumor growth and survival is also activated in...

Soils of southern South America, including Patagonia, have endured disturbances from volcanic eruptions, earthquakes, landslides, and erosion. Also, massive fires in the mid-20th century were set to forests in order to promote colonization. In 2010, another 17,000 acres of Patagonia burned, fueling...

A new study published in the Journal of Urology reports that prostate cancer patients treated with androgen deprivation therapy (ADT) experienced changes in mental and emotional well-being during treatment, although there was no meaningful decline in emotional quality of life two years after...

Sin ninguna crisis financiera severa en el radar a la que tratar de dar respuestas, el Foro Económico Mundial 2014, que se inició este miércoles 22, “buscará soluciones para los problemas realmente fundamentales”, dijo su fundador, Klaus Schwab. “No podemos darnos el lujo de permitir que la próxima...

La guerra civil en Siria tiene su fiel reflejo en esta norteña ciudad de Líbano, donde dos barrios están enfrentados apoyando a sendos bandos del conflicto en ese vecino país. Las hostilidades no cesan. Los barrios rivales de Jabal Mohsen y Bab Al Tabbaneh, separados por la Calle Siria, han sido...

Entre 2007 y 2011 en las costas de México se registró alta mortalidad de abulón amarillo (Haliotis corrugata) y abulón azul (Haliotis fulgens), moluscos que son considerados un manjar de exportación hacia Japón y Estados Unidos. Para entender y evitar que se repita ese fenómeno, el Centro de Investigaciones Biológicas del...

A new study from the Florida campus of The Scripps Research Institute (TSRI) offers insights into how aging affects the brain’s neural circuitry, in some cases significantly altering gene expression in single neurons. These discoveries could point the way toward a better understanding of how aging affects our cognitive ability...

Vecinos de un aguerrido pueblo de Argentina ganaron un primer round contra la gigante de biotecnología Monsanto, pero siguen en pie de combate, conscientes de que queda mucho para ganar la pelea.  En Malvinas Argentinas, una localidad de la central provincia de Córdoba, llevan cuatro meses de...

Metastatic melanoma has a poor prognosis, but treatment with high-dose interleukin-2 (IL2) can extend survival. Now, a combination of IL2 therapy and activation of patients' immune systems using personalized vaccines made from their own tumor cells has been shown to improve survival rates even more than IL2 alone, according to...

A new study demonstrates that the abnormal metabolism linked to obesity could be regulated in part by the interaction of two metabolic regulators, called the NAD-dependent deacetylase SIRT1 and fibroblast growth factor 21. Using experimental models, the researchers found that a lack of SIRT1 protein in the liver led to lower...
