Porto Alegre, Brazil- Tumor progression is usually ensured by more than one proliferative mechanism. When one of these is shut down by a specifically targeted drug, other mechanisms may emerge. While these events may lead to treatment failure, they may also become an opportunity for researchers to identify novel targets to be further explored. In a paper recently published in the journal Oncology ("BDNF/TrkB content and interaction with gastrin-releasing peptide receptor blockade in colorectal cancer," Vol. 79, pages 430-439, 2011; DOI: 10.1159/000326564) Roesler and colleagues ...

London - 26 April, 2011 – A study, completed by researchers from Trinity College and the Research Institute for a Tobacco Free Society, Dublin, Ireland, compares former smokers to current smokers, and obtains insight into how to quit smoking might be discovered by studying the brains of those who have successfully managed to do so. Functional MRI images were obtained while current smokers, former smokers and never smokers performed tasks designed to assess specific cognitive skills that were reasoned to be important for smoking abstinence. These included a response ...

An invention by Rice University bioengineering students in collaboration with the Texas Heart Institute (THI) is geared toward giving immediate second chances to arrhythmia victims headed toward cardiac arrest. For their capstone design project, a team of Rice seniors created a unique pad system for automated external defibrillators (AEDs), common devices that can shock a victim's heart back into a proper rhythm in an emergency. Often, the first shock doesn't reset a heart and the procedure must be repeated, but the sticky pads on the chest must first be repositioned. ...

High blood pressure, or hypertension, is more common and often more deadly in blacks than in whites, and a new University of Rochester study shows that low vitamin D levels among black people might be a powerful factor that contributes to the racial differences in hypertension. The University of Rochester Medical Center findings, published online today in the Journal of General Internal Medicine, are consistent with growing evidence that lower vitamin D status is associated with higher blood pressure, and that people with darker skin generally produce less vitamin D. "Our ...

BINGHAMTON, NY – It's an unfamiliar neighborhood and you find yourself in the middle of a bunch of streets and buildings you've never seen before. Giving the environment a quick once-over, you make a snap decision about whether you're safe or not. And chances are, that first 'gut' call is the right one, say Binghamton University researchers Dan O'Brien and David Sloan Wilson in an article published in the current issue of Journal of Personality and Social Psychology. In a recent series of studies conducted in Binghamton, New York, evolutionary biologists, O'Brien and ...

Governor Cuomo's proposal to limit the recovery of damages for pain and suffering to victims of medical negligence to $250,000 was, thankfully, defeated in the New York State Legislature Shamefully, however, something with a far devastating impact on the health of children injured by obstetrical negligence was passed and is now the law in New York. Buried in the $132.5 Billion Budget was the creation of the "New York Medical Indemnity Fund." Here's the way the fund works and why its consequences are so dangerous to children injured by malpractice at birth: The ...

Having power over others and having choices in your own life share a critical foundation: control, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. The paper finds that people are willing to trade one source of control for the other. For example, if people lack power, they clamor for choice, and if they have an abundance of choice they don't strive as much for power. "People instinctively prefer high to low power positions," says M. Ena Inesi of London Business School. "Similarly, it feels good when ...

Lower vitamin D levels may explain part of the disparity in hypertension that exists between Black and White people in the US. High blood pressure is more common in Blacks than in Whites and persons with darker skin generally produce less vitamin D. This is particularly true at higher latitudes where UV radiation is less intense and the climates are colder leading to less skin exposure. Dr. Kevin Fiscella, from the University of Rochester School of Medicine in the US, and colleagues identify vitamin D status as one piece of the complex puzzle of race and blood pressure. ...

People who have strokes are often left with moderate to severe physical impairments.

In addition to making powerful and secure networks, this discovery may also help sensitive measurements of magnetic fields ...

BOSTON--Dana-Farber Cancer Institute scientists have discovered new details of how cancer cells escape from tumor suppression mechanisms that normally prevent these damaged cells from multiplying. They also demonstrated a potential link between this cell proliferation control mechanism and the cognitive deficits caused by Down syndrome. The findings add to a still-sparse understanding of how normal and cancerous cell growth is regulated and have potential implications for improved treatments, say the authors of a pair of articles in Genes & Development. James A. DeCaprio, ...
