More men than women develop Parkinson’s disease and new work presented at the Federation of European Neuroscience Societies says that it is do to sex differences in how brain cells change. Parkinson’s disease affects about 9 million people and becomes increasingly prevalent with age.
EAST LANSING, Mich. -- People with intellectual disabilities are more susceptible to exploitation and abuse, and the rise of the Internet only increases their vulnerability.
A first-of-its-kind study co-authored by a Michigan State University scholar finds that adults with Williams syndrome -- who are extremely social and trusting -- use Facebook and other social networking sites frequently and are especially vulnerable to online victimization.
Roughly a third of study participants said they would send their photo to an unknown person, arrange to go to the home of a person they met online and keep online relationships from their parents.
Professional athletes suffer from sleep disorders more frequently than generally thought, however, systematic examination, counselling and individual treatment planning can improve the quality of their sleep. Published in the Journal of Sports Sciences, a new Finnish study clearly shows for the first time that systematic measures can improve the sleep of professional athletes.
The results of a new survey published in ecancermedicalscience indicate that a majority of oncology professionals believe that writing condolence letters to the families of deceased patients is an important component of cancer palliative care.
The study explored whether institutions should consider changing policies to raise condolence letters to a more official standing.
But because this practice is a personal grace note, it has rarely been studied or discussed. In particular, this issue hasn't been researched in the UK, where cultural practices surrounding grief are often private.
Amsterdam, May 19, 2016 -- Dirty laundry smells bad because of certain chemicals called volatile organic compounds, which can't always be washed out on an eco-friendly 20?C cycle, according to a new study in the Journal of Chromatography A.
Consumers' awareness of the ecological impacts of washing - the temperature of the wash and the detergent they use - is increasing, so it is important to understand why dirty clothes smell, in order to find the best way to clean them. The researchers behind the new study, from Northumbria University, say the chemicals they identified could be used to test the effectiveness of washing at different temperatures.
Neuherberg, May 19, 2016. One year after the introduction of the Bavarian pilot project Fr1da, the Institute of Diabetes Research, Helmholtz Zentrum München has published the first results in the BMJ Open journal. None of the 105 children who have been diagnosed with An early stage of type 1 diabetes have suffered from metabolic imbalance so far.
A new USC-led study identified a "sunscreen" gene that may help stave off skin cancer.
The researchers found that the "UV radiation Resistance Associated Gene" is a tumor suppressor for skin cancer, which is the most common form of cancer in the United States. Melanoma is the deadliest skin cancer. In fact, melanoma rates have doubled over the last three decades, according to the Centers for Disease Control and Prevention.
A large proportion of cancer cases and deaths among U.S. individuals who are white might be prevented if people quit smoking, avoided heavy drinking, maintained a BMI between 18.5 and 27.5, and got moderate weekly exercise for at least 150 minutes or vigorous exercise for at least 75 minutes, according to a new study published online by JAMA Oncology.
Cancer is a leading cause of death in the United States.
Stem cells are typically thought to have the intrinsic ability to generate or replace specialized cells. However, a team of biologists at NYU showed that regenerating plants can naturally reconstitute their stem cells from more mature cells by replaying embryogenesis.
"Paradoxically, this means that, in this system, stem cells don't immediately generate the plant's tissue, but, rather, tissues make stem cells," explains Kenneth Birnbaum, an associate professor in New York University's Department of Biology and the study's senior author.
New York, NY (May 19, 2016) - Scientists at The New York Stem Cell Foundation (NYSCF) Research Institute discovered an important biological phenomenon in human cells that will help scientists and clinicians design safer treatments to prevent mitochondrial diseases. NYSCF first pioneered a technique, mitochondrial replacement therapy (MRT), in 2012 to prevent inheritance of these devastating and debilitating diseases. Now, scientists at the NYSCF Research Institute and Columbia University are working to hone this technique and understand the biological processes that would impact patients as this process is brought into clinical trials.
In the bird world, the color red has special significance. Many species use red signals to attract mates or deter rivals, adding the color to their beaks, feathers, or bare skin. Generally speaking, as far as many birds are concerned, redder is better. Now, two teams of researchers have independently identified an enzyme-encoding gene that allows some bird species to convert yellow pigments from their diets into that remarkable red. Their findings are reported on May 19 in Current Biology.
Mitochondrial replacement therapy, where a nucleus from a mother's egg cell is transferred into a donor egg containing healthy mitochondria, shows promise for preventing the inheritance of mitochondrial DNA diseases. However, small amounts of mitochondrial DNA can sometimes hitch a ride with the transferred nucleus, and a study publishing May 19 in Cell Stem Cell shows that this DNA can override the mitochondria in the donor cell. The findings may call into question the beneficial effect of nuclear transfer for mitochondrial replacement therapy.
