MGH researchers develop bioartificial replacement limbs suitable for transplantation

A team of Massachusetts General Hospital investigators has made the first steps towards development of bioartificial replacement limbs suitable for transplantation. In their report, which has been published online in the journal Biomaterials, the researchers describe using an experimental approach previously used to build bioartificial organs to engineer rat forelimbs with functioning vascular and muscle tissue.

Scientists identify novel mechanism that can reorganize cell's genetic architecture to promote senescence

Senescence, a phenomenon in which cells cease to divide and grow, can be caused by everything from natural DNA damage to treatment with chemotherapy. However, several mechanisms allow for cells to bypass senescence and grow out of control, eventually becoming cancerous.

Portable microendoscope could eliminate need for costly biopsies for esophageal cancer patients

In a clinical study of patients in the United States and China, researchers found that a low-cost, portable, battery-powered microendoscope developed by Rice University bioengineers could eventually eliminate the need for costly biopsies for many patients undergoing standard endoscopic screening for esophageal cancer.

March of Dimes funds studies that explore factors, mechanisms involved in placental malaria

Malaria infection during pregnancy poses serious risks to women and infants. The March of Dimes Foundation, an American organization that works to improve pregnancy and baby health, has now funded Carlos Penha-Goncalves' laboratory, at the Instituto Gulbenkian de Ciencia (IGC, Portugal), for their studies on factors and mechanisms involved in placental malaria. This is the first time that this American Foundation funds research from a Portuguese Institution.

National Psoriasis Foundation awards grants to support psoriatic disease research

The National Psoriasis Foundation awarded eight researchers each a one-year, $75,000 Discovery Grant to support the advancement of psoriatic disease research. By gaining a better understanding of the fundamentals of psoriatic disease--what causes psoriasis and psoriatic arthritis and what happens in the body when these diseases are present--scientists can work on better treatments and a cure.

Researchers transform bacteria into 'secret agents' for detecting disease

Another step forward has just been taken in the area of synthetic biology. Research teams from Inserm and CNRS (French National Centre for Scientific Research) Montpellier, in association with Montpellier Regional University Hospital and Stanford University, have transformed bacteria into "secret agents" that can give warning of a disease based solely on the presence of characteristic molecules in the urine or blood. To perform this feat, the researchers inserted the equivalent of a computer programme into the DNA of the bacterial cells.

University of Bonn researchers find way to stimulate larynx muscles using light

Researchers at the University of Bonn have found a way to stimulate the larynx muscles of mice using light. In the long term, this method could be an option for the treatment of laryngeal paralysis, which causes difficulties in phonation and breathing. Their findings will be published in the scientific journal "Nature Communications."

Northeastern University researcher reports finding epicenter of brain's prediction

In recent years, scientists have discovered the human brain works on predictions, contrary to the previously accepted theory that it reacts to the sensations it picks up from the outside world. Experts say humans' reactions are in fact the body adjusting to predictions the brain is making based on the state of our body the last time it was in a similar situation.

Tools that help decide use of expensive imaging studies can reduce ordering of unnecessary tests

Using tools that help physicians decide whether to use expensive imaging studies such as MRI scans can help reduce the ordering of unnecessary tests, but implementation of the tools in real-world settings has many challenges, according to a new RAND Corporation study.

Bariatric surgery leads to greater intimacy between patients and their life partners

Bariatric surgery does not only benefit the health of patients who undergo this weight loss procedure. It also leads to greater intimacy between them and their life partners, and adds a spark to their sex life. It's all in all a shared journey that brings partners closer together, says Mary Lisa Pories of East Carolina University in the US, lead author of a study providing insights into the experience of couples after one of the partners underwent weight loss surgery.

Teens start misusing ADHD drugs and other stimulants earlier than you might think

Despite stereotypes about college students resorting to black-market Ritalin to help them cram for exams, young people are actually most likely to start misusing prescription stimulant drugs in their high school years, according to new University of Michigan Medical School research.
