Ten young researchers named Pew Latin American Fellows in the Biomedical Sciences

Ten young researchers were named Pew Latin American Fellows in the Biomedical Sciences today by The Pew Charitable Trusts. For these scientists, who have dedicated their careers to finding solutions for some of the world's most troubling health problems, this fellowship will provide support that will further their research, enable them to work with colleagues in the United States, and increase scientific knowledge throughout their home region.

New method enhances adhesion of injected CECs for successful corneal transplantation

Regenerative medicine, or the use of specially grown tissues and cells to treat injuries and diseases, has been successful in treating disorders of a number of organs, including heart, pancreas, and cartilage. However, efforts to treat disorders of the corneal endothelium, a single cell layer on the inner surface of the cornea, with regenerative techniques have been less effective. Now, a group of scientists has developed a method that enhances the adhesion of injected corneal endothelial cells (CECs), allowing for successful corneal transplantation to repair pathological dysfunctions.

MIT engineers develop new glucose-powered implantable medical device

MIT engineers have developed a fuel cell that runs on the same sugar that powers human cells: glucose. This glucose fuel cell could be used to drive highly efficient brain implants of the future, which could help paralyzed patients move their arms and legs again.

Study investigates how breast cancer cells migrate to bone

Breast cancer cells frequently move from their primary site and invade bone, decreasing a patient's chance of survival. This process of metastasis is complex, and factors both within the breast cancer cells and within the new bone environment play a role. In next week's Journal of Biological Chemistry "Paper of the Week," Roger Gomis and colleagues at the Institute for Research in Biomedicine in Spain investigated how breast cancer cells migrate to bone.

Researchers use brain imaging to uncover susceptibility to psychological stress and trauma

Most people have intense emotional reactions to traumatizing events like road accidents or combat. But some suffer far longer, caught in the grip of long-term debilitating disorders such as Post-Traumatic Stress Disorder (PTSD). Because doctors cannot predict who will develop these disorders, however, early or preventive intervention is not available. Now, a new project led by researchers at Tel Aviv University seeks to identify pre-traumatic subjects - those who are more susceptible to long-standing disorders if exposed to a traumatic incident.

US Oncology Research, MMRF partner to participate in CoMMpass study

The Multiple Myeloma Research Foundation (MMRF) today announced an alliance with US Oncology Research to participate in the landmark CoMMpass (Relating Clinical Outcomes in MM to Personal Assessment of Genetic Profile) study sponsored by the MMRF.

High anxiety can turn good dads bad

Normally, male California mice are surprisingly doting fathers, but new research published in the journal Physiological and Biochemical Zoology suggests that high anxiety can turn these good dads bad.

Human-derived stem cells can spontaneously form optic cups and retina

Human-derived stem cells can spontaneously form the tissue that develops into the part of the eye that allows us to see, according to a study published by Cell Press in the 5th anniversary issue of the journal Cell Stem Cell.

RNA-binding proteins accumulate in the brains of patients with AD

Researchers from Boston University School of Medicine (BUSM) have identified a novel group of proteins that accumulate in the brains of patients with Alzheimer's disease. These findings, which appear online in the Journal of Neuroscience, may open up novel approaches to diagnose and stage the progression likelihood of the disease in Alzheimer patients.

Novo Nordisk, JDRF partner to discover and develop novel immunotherapies against T1D

To address the underlying autoimmune process that is central to type 1 diabetes (T1D), JDRF and Novo Nordisk are partnering to discover and develop novel immunotherapies to prevent, treat, and help cure the disease.

New microfluidic device can sort cancer cells, particles

In life, we sort soiled laundry from clean; ripe fruit from rotten. Two Johns Hopkins engineers say they have found an easy way to use gravity or simple forces to similarly sort microscopic particles and bits of biological matter -- including circulating tumor cells.

New study on motor chunking

You pick up your cell phone and dial the new number of a friend. Ten numbers. One. Number. At. A. Time. Because you haven't actually typed the number before, your brain handles each button press separately, as a sequence of distinct movements.

Scientists decipher and block a molecular message that prompts unbridled cellular growth

What's good news in one setting might spell disaster in another. In cancer for instance, when a certain cell is commanded to grow and divide without restraint, it's a welcome message for the cell itself but a tragedy for the person who harbors this cell in his or her body. Weizmann Institute scientists have managed to decipher and block one type of molecular message that prompts unbridled cellular growth.

Researchers identify prognostic marker in chronic lymphocytic leukemia

Researchers have identified a prognostic marker in the most common form of chronic leukemia that can help to distinguish which patients should start treatment quickly from those who can safely delay treatment, perhaps for years.

Long-lasting weekly fertility injections work as well as daily

New long-lasting weekly injections of fertility hormones are as safe and effective as standard daily injections, according to Cochrane researchers. The researchers compared weekly and daily hormone injections in a Cochrane systematic review and found no difference in pregnancies or serious side effects between the two regimens.

HLA B-27 protein appears to confer ability to suppress HIV viral replication

The rare ability of some individuals to control HIV infection with their immune system alone appears to depend - at least partially - on specific qualities of the immune system's killer T cells and not on how many of those cells are produced.

Caspase-11 enzyme plays an important role in Legionella infection

New research shows that an enzyme that has long been considered relatively useless to the immune response instead has an important role in setting up immune cells to kill infection-causing bacteria.
