Mount Sinai receives Le Foundation gift for psychiatric neuroimaging study

The Department of Psychiatry at Mount Sinai School of Medicine has received a $250,000 gift from The Iris & Junming Le Foundation to advance neuroimaging research conducted by young scientists in the early stages of their careers.

Researchers discover how mTOR protein leads to cancer metastasis

Uncovering the network of genes regulated by a crucial molecule involved in cancer called mTOR, which controls protein production inside cells, researchers at the University of California, San Francisco (UCSF) have discovered how a protein "master regulator" goes awry, leading to metastasis, the fatal step of cancer.

Study examines abdomyosarcoma growth in mouse models of muscular dystrophy

Inflammation, cell division and cell differentiation that occur during skeletal muscle regeneration may provide an ideal environment for the highly malignant tumor, rhabdomyosarcoma to arise. These are the findings from a Nationwide Children's Hospital study that examined rhabdomyosarcoma growth in mouse models of muscular dystrophy.

Patterns of brain development are distinct in infants with ASD

Patterns of brain development in the first two years of life are distinct in children who are later diagnosed with autism spectrum disorders (ASDs), according to researchers in a network funded by the National Institutes of Health. The study results show differences in brain structure at 6 months of age, the earliest such structural changes have been recorded in ASDs.

First molecular evidence links body's natural circadian rhythms to SCD

A fundamental discovery reported in the March 1st issue of the journal Nature, uncovers the first molecular evidence linking the body's natural circadian rhythms to sudden cardiac death (SCD). Ventricular arrhythmias, or abnormal heart rhythms, are the most common cause of sudden cardiac death: the primary cause of death from heart disease.

Insight into relationship between two types of suppressors in cancerous tumors

The University of Kentucky has announced that Dr. Daret St. Clair, the James Graham Brown Endowed Chair and professor of toxicology, has published the first comprehensive study that provides insight into the relationship between two types of suppressors in cancerous tumors. The results will enhance the understanding of transcriptional mechanisms in carcinogenesis.

Candida albicans can sense immune status of host cells and evade them

Glen Palmer, PhD, Assistant Professor of Microbiology, Immunology & Parasitology at LSU Health Sciences Center New Orleans, was part of an international research team led by Luigina Romani, MD, at the University of Perugia, that discovered opportunistic fungi like Candida albicans can sense the immune status of host cells and adapt, evading immune system defenses.

Targeting versican protein may help stop breast cancer metastasis

Oncologists have known that in order for cancer cells to spread, they must transform themselves so they can detach from a tumor and spread to a distant organ. Now, scientists at Weill Cornell Medical College have revealed critical steps in what happens next -- how these cells reverse the process, morphing back into classical cancer that can now grow into a new tumor.

Computer-assisted cognitive rehabilitation benefits patients with relapsing-remitting MS

In a new study published in the March issue of Radiology, functional magnetic resonance imaging (fMRI) shows that cognitive rehabilitation changes brain function and improves cognitive performance in patients with relapsing-remitting multiple sclerosis (MS).

Chemists build light-controlled neural inhibitor

The notion of a pain switch is an alluring idea, but is it realistic? Well, chemists at LMU Munich, in collaboration with colleagues in Berkeley and Bordeaux, have now shown in laboratory experiments that it is possible to inhibit the activity of pain-sensitive neurons using an agent that acts as a photosensitive switch. For the LMU researchers, the method primarily represents a valuable tool for probing the neurobiology of pain.

New microfluidic device can rapidly isolate target cells

Separating complex mixtures of cells, such as those found in a blood sample, can offer valuable information for diagnosing and treating disease. However, it may be necessary to search through billions of other cells to collect rare cells such as tumor cells, stem cells or fetal cells. "You're basically looking for a needle in a haystack," says Sukant Mittal, a graduate student in the Harvard-MIT Division of Health Sciences and Technology.

China's SFDA approves Dynex DS2 ELISA analyzer

Dynex Technologies announced today it has received approval from China's State Food and Drug Administration (SFDA) to market the DS2 automated enzyme-linked immunosorbent assay (ELISA) analyzer in China.

Causal link between TBI and increased susceptibility to PTSD

Mild traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD) are cardinal injuries associated with combat stress, and TBI increases the risk of PTSD development. The reasons for this correlation have been unknown, in part because physical traumas often occur in highly emotional situations.
