Engineered nanomaterials inhalation negatively impacts gestational development in animal models

After a decade of rapidly growing industrial use, unimaginably tiny particles surround us everywhere, every day, in everything we do. Used in the manufacturing of cosmetics, clothing, paints, food, drug delivery systems and many other familiar products we all use daily, little is known about the effects these materials have on health.

Disturbances in body insulin levels linked with increased risk of obesity-related cancers

It is estimated that over a third of the new cancer cases expected to occur in the U.S. in 2013 will be related to overweight or obesity, physical inactivity, and poor nutrition. Thanks to the work of one NYU Steinhardt researcher, we may better understand why.

MacLean Center receives Cornerstone Award for outstanding contributions in field of bioethics

The University of Chicago Medicine's MacLean Center for Clinical Medical Ethics has been awarded the prestigious Cornerstone Award from the American Society of Bioethics and Humanities for "outstanding contributions from an institution that has helped shape the direction of the fields of bioethics and/or medical humanities."

MGH researchers identify rare gene mutations that appear to cause late-onset AD

Massachusetts General Hospital (MGH) researchers have identified and validated two rare gene mutations that appear to cause the common form of Alzheimer's disease (AD) that strikes after the age of 60.

Researchers identify molecular pathway linking ICU ventilation to brain damage

At least 30 percent of patients in intensive care units (ICUs) suffer some form of mental dysfunction as reflected in anxiety, depression, and especially delirium. In mechanically-ventilated ICU patients, the incidence of delirium is particularly high, about 80 percent, and may be due in part to damage in the hippocampus, though how ventilation is increasing the risk of damage and mental impairment has remained elusive.

Simple traffic light test helps reduce drinking rates in people with risk of liver disease

A simple 'traffic light' test that detects hidden liver fibrosis and cirrhosis in high risk populations could reduce harmful drinking rates and potentially prevent hundreds of alcohol-related deaths a year.

DASH diet improves heart function, lowers blood pressure in heart failure patients

Diet can dramatically lower hypertension and improve heart function in patients with a common type of heart failure, according to research presented at today's Heart Failure Society of America meeting in Orlando, Fla.

Researchers show link between FTO gene and hip fracture in women

Australian researchers have demonstrated a strong association between the FTO (fat and obesity) gene and hip fracture in women. While the gene is already well known to affect diabetes and obesity, this is the first study to show that its high-risk variant can increase the risk of hip fracture by as much as 82%.

miR-31 in primary tumor cells predicts lymph node metastasis in NSCLC patients

Determining whether a patient's lung cancer has spread to nearby lymph nodes is critical for identifying the most effective therapy, but it usually requires surgery. A new study suggests, however, that measuring levels of a particular molecule in a sample of tumor tissue might accurately answer the question.

Study shows how deadly Candida albicans might be rendered harmless

Candida albicans is a double agent: In most of us, it lives peacefully, but for people whose immune systems are compromised by HIV or other severe illnesses, it is frequently deadly. Now a new study from Johns Hopkins and Harvard Medical School shows how targeting a specific fungal component might turn the fungus from a lion back into a kitten.

Environmental enrichment protects against atrophy in chronic stages of TBI

For the first time, scientists at Toronto Rehab have found that in people with chronic moderate-severe traumatic brain injury (TBI), atrophy (shrinkage) in the brain may be countered by participating in environmental enrichment - increased physical, social and cognitive stimulation.

Rhythm starts RM-493 clinical trials in obesity patients with genetic deficiency

Rhythm announced today the initiation of the first of a series of clinical trials with RM-493, the company's novel melanocortin 4 receptor (MC4R) agonist, for the treatment of obesity in individuals with a genetic deficiency in the MC4R pathway.

Caffeine intake results in delayed brain development

Humans and other mammals show particularly intensive sleeping patterns during puberty. The brain also matures fastest in this period. But when pubescent rats are administered caffeine, the maturing processes in their brains are delayed. This is the result of a study supported by the Swiss National Science Foundation (SNSF).

Long-term hormonal therapy has no additional benefits in men with intermediate-risk prostate cancer

A secondary analysis of the historic RTOG 9202 prostate cancer trial examined results of men with intermediate-risk prostate cancer who had received long-term hormonal therapy after radiation therapy, and concluded that there were no additional benefits when compared to short-term hormonal therapy, according to research presented today at the American Society for Radiation Oncology's (ASTRO's) 55th Annual Meeting.

Discovery could help develop new treatments for blood diseases

Researchers in Melbourne, Australia, have found that even our immune system is subject to performance enhancement, with our bodies giving immune cells the boost they need to ensure the best team is selected to fight infections.

Long-term abstinence from cocaine does not result in complete normalization of brain circuitry

It is often said that once people develop an addiction, they can never completely eliminate their attraction to the abused substance. New findings provide further support for this notion by suggesting that even long-term abstinence from cocaine does not result in a complete normalization of brain circuitry.

Brains could process new situations by relying on method similar to "pointer" system

Our brains give us the remarkable ability to make sense of situations we've never encountered before-a familiar person in an unfamiliar place, for example, or a coworker in a different job role-but the mechanism our brains use to accomplish this has been a longstanding mystery of neuroscience.

Lung cancer patients who received IMRT report less decline in their QOL

An analysis of quality of life (QOL) data of stage III lung cancer patients who received higher doses of radiation therapy (with chemotherapy) shows a significantly lower quality of life at 3 months after treatment compared to patients who received a standard dose of radiation (with chemotherapy), according to research presented today at the American Society for Radiation Oncology's (ASTRO's) 55th Annual Meeting.

Protein linked with asthma severity in children with high diesel exposure

A new study shows that exposure to diesel exhaust particles from traffic pollution leads to increased asthma severity in children. Moreover, the study finds that this is due to increased blood levels of IL-17A, a protein associated with several chronic inflammatory diseases, in children with high diesel exposure.

Tel Aviv University researchers develop spring-like fibers to help repair damaged heart tissue

The threat from a heart attack doesn't end with the event itself. Blockage of blood flow to the heart can cause irreversible cell death and scarring. With transplants scarce, half the people who live through a heart attack die within five years. Scientists are trying to address this problem by engineering cardiac tissue to patch up damaged areas.
