Stress can shorten telomeres at a very young age

Children who have experienced violence might really be older than their years. The DNA of 10-year-olds who experienced violence in their young lives has been found to show wear and tear normally associated with aging, a Duke University study has found.

CRG to host EuroStemCell meeting on April 27

Stem cells are in the news quite a bit, but it can be difficult to pick out the true science from the hype. How can patients, school students and members of the public make sense of this fast-changing area of research? EuroStemCell aims to meet this challenge and engage the public in developments in this complex area of science.

Researchers discover how dendritic cells exchange information to amplify immune response

Using a new fluorescent biosensor they developed, researchers at Carnegie Mellon University have discovered how a key set of immune cells exchange information during their coordinated assault on invading pathogens.

Researchers develop small endoscopic device fitted with femtosecond laser scalpel

Whether surgeons slice with a traditional scalpel or cut away with a surgical laser, most medical operations end up removing some healthy tissue, along with the bad. This means that for delicate areas like the brain, throat, and digestive tract, physicians and patients have to balance the benefits of treatment against possible collateral damage.

Computational adaptive optics for real-time in-vivo applications

Real-time, 3-D microscopic tissue imaging could be a revolution for medical fields such as cancer diagnosis, minimally invasive surgery and ophthalmology. University of Illinois researchers have developed a technique to computationally correct for aberrations in optical tomography, bringing the future of medical imaging into focus.

Researchers describe novel mechanism of HIV-1 spread by dendritic cells

A new understanding of the initial interactions of human immunodeficiency virus type 1 (HIV-1) and dendritic cells is described by Boston University School of Medicine (BUSM) researchers in a study currently featured in the Proceedings of the National Academy of Sciences.

Scientists identify new way to deliver long-lasting pain relief

Scientists at the University of North Carolina at Chapel Hill have identified a new way to deliver long-lasting pain relief through an ancient medical practice.

Cadmium exposure can cause progression of aggressive breast cancer

Studies by researchers at Dominican University of California show that breast cancer cells become increasingly aggressive the longer they are exposed to small concentrations of cadmium, a heavy metal commonly found in cosmetics, food, water and air particles.

Cancer therapy with common cold virus

Common viruses have become the latest weapon against cancer. There is the case of the eight-year-old African boy diagnosed with Burkitt's lymphoma at a Ugandan health clinic. He was exposed to the measles virus and in the next few weeks his tumour regressed completely and he entered remission. But only relatively recently have scientists clinically examined the interaction between viruses and cancers in the growing area of oncolytic virotherapy.

Study: hUC-MSCs reduce inflammation that causes colitis

When laboratory mice were modeled with colitis and treated with human umbilical cord-derived mesenchymal cells, the cells homed in on the inflamed colon and effectively ameliorated colitis, reported a study published in a recent issue of Cell Transplantation.

TopBP1 protein prevents early brain cells from DNA damage

St. Jude Children's Research Hospital scientists have rewritten the job description of the protein TopBP1 after demonstrating that it guards early brain cells from DNA damage. Such damage might foreshadow later problems, including cancer.

Novel technological treatment for Leber Hereditary Optic Neuropathy

A research team, led by John Guy, M.D., professor of ophthalmology at Bascom Palmer Eye Institute of the University of Miami Miller School of Medicine, has pioneered a novel technological treatment for Leber Hereditary Optic Neuropathy (LHON), an inherited genetic defect that causes rapid, permanent, and bilateral loss of vision in people of all ages, but primarily males ages 20-40.

HDAC6 protein may provide novel target for stress-linked disorders

A cellular protein called HDAC6, newly characterized as a gatekeeper of steroid biology in the brain, may provide a novel target for treating and preventing stress-linked disorders, such as depression and post-traumatic stress disorder (PTSD), according to research from the Perelman School of Medicine at the University of Pennsylvania.

FDA issues draft guidelines on approval process for use of nanoparticles in food and cosmetics

The United States Food and Drugs Administraton (FDA) has proposed that food companies that want to use tiny engineered particles called nanoparticles in their packaging may have to provide extra testing data to show the products are safe.

Phytochemicals in mangos may target breast cancer cells

Already one of the world's most popular fruits, scientists are discovering that mangos may also be one of the healthiest. New research, presented this week at the Federation of American Societies for Experimental Biology (FASEB) meeting in San Diego, not only suggests people who eat mangos have a better diet, but the fruit also contains a substance that may have an effect on breast cancer cell proliferation.

Brain injury in amateur boxing similar to Alzheimer´s

Olympic boxers can exhibit changes in brain fluids after bouts, which indicates nerve cell damage. This is shown in a study of 30 top-level Swedish boxers that was conducted at the Sahlgrenska Academy at the University of Gothenburg, Sweden, in collaboration with the Swedish Boxing Federation, published in PLoS ONE.
