Team Mimicking a Natural Defense Against Malaria to Develop New Treatments
One of the world's most devastating diseases is malaria, responsible for at least a million deaths annually, despite global efforts to combat it. Researchers from the Perelman School of Medicine at the University of Pennsylvania , working with collaborators from Drexel University, The Children's Hospital of Philadelphia, and Johns Hopkins University, have identified a protein in human blood platelets that points to a powerful new weapon against the disease.

Team Developing New Class of Malaria Drugs Using Essential Calcium Enzyme
Calpain, a calcium-regulated enzyme, is essential to a host of cellular processes, but can cause severe problems in its overactivated state. It has been implicated as a factor in muscular dystrophy, AIDS, Alzheimer's disease, multiple sclerosis, and cancer. As such, finding and exploiting calpain inhibitors is an important area of research.

Lethal weapon: bacteria’s high-risk suicide strategy
Lethal weapon: bacteria’s high-risk suicide strategy
" Research published today in the journal Proceedings of the National Academy of Sciences shows that some bacterial cells carry a molecular 'suicide complex' to kill themselves in the event of lethal infection by viral parasites. Such 'altruistic suicide' prevents or limits viral replication and protects the rest of the bacterial population from subsequent infection.

Youth seeking weight loss treatment report bullying by those they trust
Even as adolescents struggle to lose weight through treatment programs, they often continue to experience weight-based discrimination - not just from their peers, but from adults they trust, including parents and teachers. The study by researchers at the Rudd Center for Food Policy & Obesity at Yale appears online in the journal Pediatrics, and is the first comprehensive examination of how weight-based victimization impacts youth seeking weight-loss treatment.

Study turns parasite invasion theory on its head
Current thinking on how the Toxoplasma gondii parasite invades its host is incorrect, according to a study published today describing a new technique to knock out genes. The findings could have implications for other parasites from the same family, including malaria, and suggest that drugs that are currently being developed to block this invasion pathway may be unsuccessful.

Understanding cell organisation to tackle cancer
Understanding cell organisation to tackle cancer
23 Dec 2012 Charles Streuli and Nasreen Akhtar of the Wellcome Trust Centre for Cell-Matrix Research have conducted new research that leads to a better understanding of cell polarity. Properly organised tissues are vital to maintaining functional organs and a healthy body. Part of being organised includes cells being in the correct position within the tissue and the right way up, because the top and bottom of cells have different functions.

New research findings on causes of suicide
A new research report sheds fresh light on the processes in the brain that can lead to suicide. In tests on patients who have previously tried to take their own lives, researchers have measured high levels of quinolinic acid, a substance that strengthens glutamate signalling in the brain. Quinolinic acid is formed in the brain as a by-product of inflammation.

Could normal water prevent diabetes, obesity and cardiovascular disease?
Researchers at Lund University, Sweden, are studying whether it is possible to prevent obesity, diabetes and cardiovascular disease by reducing levels of the hormone vasopressin in the blood. “If you dilute the blood by drinking water, the body releases less of the hormone vasopressin, which can potentially lead to diabetes”, says Sofia Enhörning, a doctor who has recently completed her PhD at Lund University.

Genetic differences may influence sensitivity to pain
A team of scientists led by King's College London has identified a particular set of genes that interact with one another to regulate pain in humans, and found that differences in these genes may influence people's sensitivity to pain. The study, published today in PLoS Genetics , adds to a growing body of evidence that particular genes are involved in chronic pain and highlights this pathway as a potential target for more effective pain relief treatments for patients.

Brain imaging insight into cannabis as a pain killer
Brain imaging insight into cannabis as a pain killer
The pain relief offered by cannabis varies greatly between individuals, a brain imaging study carried out at the University of Oxford suggests. The researchers found that an oral tablet of THC, the psychoactive ingredient in cannabis, tended to make the experience of pain more bearable, rather than actually reduce the intensity of the pain.

Major source of evolutionary differences among species
Researchers have uncovered a genetic basis for fundamental differences between humans and other vertebrates that could also help explain why humans are susceptible to diseases not found in other species. Scientists have wondered why vertebrate species, which look and behave very differently from one another, nevertheless share very similar repertoires of genes.

Child abuse risks: parent's addiction, unemployment and divorce
Adults whose parents struggled with addiction, unemployment and divorce are 10 times more likely to have been victims of childhood physical abuse, says a new study from the University of Toronto. More than one-third of adults who grew up in homes where all three risk factors were present reported they had been physically abused by someone close to them while under the age of 18 and still living at home, said researchers at U of T's Factor-Inwentash Faculty of Social Work.
