Physicians have long observed that binge drinking impairs healing of broken bones. A new study is providing insights into how alcohol slows healing on the cellular and molecular levels. The findings could lead to better treatments to improve bone healing. Fuente :...

A unique study of 16 pairs of identical twins in which one twin is obese and the other lean has yielded some surprising results. In 8 of the pairs of twins, the obese twin was as 'metabolically healthy' as his or her lean co-twin, while in the other 8 pairs, the obese twin had a poorer blood fat...

A global hunt for genes that influence heart disease risk has uncovered 157 changes in human DNA that alter the levels of cholesterol and other blood fats -- a discovery that could lead to new medications. Each of the changes points to genes that can modify levels of cholesterol and other blood...

It sounds unlikely: a washing machine recycles used detergent in order to use it again for the next load of dirty washing. But this is just what happens during the degradation of pollutants in the atmosphere. Jülich scientists have now been able to demonstrate this for the first time for isoprene,...

Biologists of the University of Zurich have developed a method to visualize the activity of genes in single cells. The method is so efficient that, for the first time, a thousand genes can be studied in parallel in ten thousand single human cells. Applications lie in fields of basic research and...

Scientists have discovered huge ice channels beneath a floating ice shelf in Antarctica. At 250 meters high, the channels are almost as tall as the Eiffel tower and stretch hundreds of kilometers along the ice shelf. The channels are likely to influence the stability of the ice shelf and their...

Investigators at the Feinstein Institute for Medical Research have discovered a protein in the human body that can trigger and mediate inflammation in patients suffering from hemorrhage and sepsis. Fuente : http://www.eurekalert.org/pub_releases/2013-10/nsi...

New research now reveals that one class of inhibitory neurons -- called VIP interneurons -- specializes in inhibiting other inhibitory neurons in multiple regions of cortex, and does so under specific behavioral conditions. The new research finds that VIP interneurons, when activated, release...

Six new Sjögren's syndrome-related genes have been discovered by an international group of researchers in a genome-wide association study. Previously, only one Sjögren's gene was known. Fuente : http://www.eurekalert.org/pub_releases/2013-10/omr...

This press release is in support of a presentation by Professor Gerard Sanacora on Sunday 6 October at the 26th ECNP Congress in Barcelona, Spain. Depression is one of the leading causes of disability worldwide. New research suggests that targeting the glutamergic system may represent an exciting...

Una investigación, en la que participan científicos del Centro Nacional de Biotecnología (CSIC), en España, ha desvelado la estructura de la cola del virus bacteriófago T7. El pasado año ya publicaron en la revista PNAS la estructura de una de las proteínas que permite a este virus anclarse...

Los chequeos y pruebas diagnósticas que en muchas ocasiones son útiles para quienes quieren ir al extranjero a trabajar se han convertido en uno de los productos de salud más demandados en España a través de Internet, según los datos recogidos en el segundo trimestre de 2013 por la plataforma......

Unlike in normal-weight mice with kidney disease, a degradation process called autophagy is suppressed in obese mice with kidney disease. This suppression leads to kidney cell damage. Obese kidney disease patients also have suppressed autophagy. Fuente :...

A skin infection linked to exposure to contaminated water in home aquariums is frequently under-diagnosed, according to a Henry Ford Hospital study.Researchers say diagnosing and managing Mycobacterium marinum infection is difficult because skin lesions don't appear for two to four weeks after...

Three years after an earthquake killed more than 200,000 people and left an estimated 1.5 million people homeless in Haiti, a Henry Ford Hospital study found that more mobilized medical care is necessary to bridge cultural and health care barriers and better serve the Haitian population.

El sistema inmune de la ballena azul del Golfo de México es tan bueno como el de los humanos y otros mamíferos terrestres; la especie es sana y podría resistir una epidemia de bacterias u hongos. Así lo da a conocer el primer estudio en su tipo que se lleva a cabo a nivel mundial por investigadores...

La contaminación del agua con arsénico promovida por la actividad minera en Torreón, Lerdo y Gómez Palacios, Coahuila, motivó a un estudiante del Instituto Tecnológico de El Salto a diseñar un filtro electromagnético para la purificación del vital líquido, el cual es capaz de extraer el 99.5 por...

Although they are at higher risk for cervical cancer, girls from low-income families are less likely to receive the human papillomavirus vaccine that prevents it, and the reasons they are not fully vaccinated differ depending on whether their parents are English-speaking or Spanish-speaking,...

When you heat a tiny droplet of liquid tin with a laser, plasma forms on the surface of the droplet and produces extreme ultraviolet (EUV) light, which has a higher frequency and greater energy than normal ultraviolet. Now, researchers have mapped this EUV emission and developed a theoretical model...
