Unavoidable damage caused to the heart and lungs by radiotherapy treatment of tumors in the chest region can be limited by the administration of a drug commonly used in the treatment of cardiovascular disease, an ACE inhibitor, a group of Dutch researchers have found. Fuente :...

Intensity modulated radiotherapy gives better results than standard radiotherapy in patients with early breast cancer, according to results from a randomised trial presented on Sunday to the 2nd Forum of the European Society for Radiotherapy and Oncology. IMRT is an advanced, high-precision form of...

Mathematical prediction models are better than doctors at predicting the outcomes and responses of lung cancer patients to treatment, according to new research. The researcher says she considers it unethical for treatment decisions to be based solely on doctors' opinions, when these models perform so much better. Fuente :...

Researchers have shown for the first time that it is possible to reduce the distressing symptoms of dry mouth in patients treated with radiotherapy for head and neck cancers if the radiation dose to a salivary gland on the opposite side to the tumor is kept to the minimum. The largest study yet to show a correlation between...

Two large, landmark radiotherapy studies have shown that it is possible to treat cervical cancer effectively with high doses specifically adapted to each tumor, and with fewer serious side-effects to the surrounding normal organs. In two presentations on Saturday and Sunday researchers will tell the 2nd Forum of the European...

A new genome-wide association study of more than 6,000 people has identified seven new genetic regions associated with pulmonary fibrosis. Researchers have found a number of genes associated with host defense, cell-cell adhesion and DNA repair, which provide clues to possible mechanisms underlying...

A new global-scale modeling study that takes into account nitrogen -- a key nutrient for plants -- estimates that carbon emissions from human activities on land were 40 percent higher in the 1990s than in studies that did not account for nitrogen. Plant regrowth -- and therefore carbon assimilation...

Researchers have found that alternative splicing -- a process that allows a single gene to code for multiple proteins -- appears to be a new potential target for anti-telomerase cancer therapy. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/y...

Researchers have shown a statistically significant association between neuropsychological (NP) test performance and memory complaints in post-treatment, early stage breast cancer patients. Patient-reported memory difficulties were also associated with having received chemotherapy and radiation and...

La colaboración internacional CDMS ha presentado durante una reunión de la Sociedad Americana de Física algunos resultados que podrían corresponder a colisiones de las hipotéticas partículas de materia oscura. Para realizar el estudio, en el que participan la Universidad Autónoma de Madrid y el...

Más de 8 años después de la publicación en la revista Science del hallazgo de la pelvis Pau, un equipo internacional de investigadores de la Universidad de Missouri y del Institut Català de Paleontologia Miquel Crusafont describen estos fósiles encontrados en el Abocador de Can Mata (Barcelona) en 2003.

La calidad del aire en bares, restaurantes y lugares de ocio nocturno ha experimentado en apenas tres años una extraordinaria mejoría. En 2008, cuando la legislación española permitía fumar con limitaciones, el humo en el interior de estos locales era de 204 microgramos por metro cúbico. En 2011, ya implementada la nueva ley...

Investigadores del grupo de investigación en cáncer hereditario del Instituto de Investigación Biomédica de Bellvitge y del Instituto Catalán de Oncología han realizado un estudio funcional y estructural de siete variantes del gen BRCA1, con significado biológico desconocido, y han concluido que tres de estas variantes son...
