Race and gender may influence use of drugs, drinking and smoking among teens

Cigarette use among white teenagers is substantially higher than among black and Hispanic teenagers, especially at 18 years old, according to Penn State researchers. Alcohol and marijuana use are also higher in white teenagers, and the numbers continue to increase until age 20. Throughout their 20s, blacks and Hispanics are more likely to pick up a cigarette-smoking habit, while the numbers start to decrease for whites.

McGill researchers identify key mechanism by which environmental factors influence traits

Until now scientists have believed that the variations in traits such as our height, skin colour, tendency to gain weight or not, intelligence, tendency to develop certain diseases, etc., all of them traits that exist along a continuum, were a result of both genetic and environmental factors. But they didn't know how exactly these things worked together.

Neuralstem reports top line data from NSI-566 Phase II trial for treatment of ALS

Neuralstem, Inc. announced top line data from the Phase II trial of NSI-566 spinal cord-derived neural stem cells under development for the treatment of amyotrophic lateral sclerosis (ALS). The study met primary safety endpoints. The maximum tolerated dose of 16 million transplanted cells and the surgery was well tolerated.

Researchers developing new mercury-free material to treat tooth decay

Tooth decay is a serious health problem and it is often necessary to repair cavities. Today they often use a composite filling material made of acrylate compounds, as it resembles the colour of the teeth and is reasonably strong so it can handle the rigors of the powerful chewing movements.

Medicine-loaded nanoparticles could help patients achieve corneal transplant success

There are about 48,000 corneal transplants done each year in the U.S., compared to approximately 16,000 kidney transplants and 2,100 heart transplants. Out of the 48,000 corneal transplants done, 10 percent of them end up in rejection, largely due to poor medication compliance. This costs the health care system and puts undue strain on clinicians, patients and their families.

Study finds that reformulated OxyContin forces some drug abusers to switch to heroin

A reformulation of OxyContin that makes it harder to abuse has curtailed the drug's illicit use. But some 25 percent of drug abusers entering rehab said they still abused the prescription painkiller despite package labeling that emphasizes its abuse-deterrent properties, new research indicates.

Study finding suggests importance of individually-tailored treatment for depression

The most commonly used treatment for the over 14 million Americans who suffer from Major Depressive Disorder is anti-depressant medication. While such medications bring relief to many, current research suggests that one size may not fit all when it comes to treating depression.

Promising new natural treatment for Alzheimer's disease nears clinical trial

A promising new natural treatment for Alzheimer's disease is moving toward clinical trials. This will be a major step forward as there is nothing on the market that slows the progression of Alzheimer's.

More research needed to explore toxicity of cellulose nanocrystals, says Virginia Tech scientist

Are cellulose nanocrystals harmful to human health? The answer might depend on the route of exposure, according to a review of the literature by a Virginia Tech scientist, but there have been few studies and many questions remain.

New X-ray diagnostic imaging designed to meet the needs of hospitals in developing countries

In developing countries, many hospitals have become cemeteries of medical equipment. Several radiology systems, often sent by international aid, may never be used due to the climatic conditions and the instability of electricity networks. In a matter of weeks, they become useless. Besides, the lack of qualified personnel or spare parts rapidly dispels any hope to make them work. Yet, the lack of access to radiology in many developing countries is a serious public health problem, whether for TB screening or the care of road traffic injuries.

McGill researchers discover that lots of useful medical information getting lost

Lots of potentially useful medical information is getting lost. McGill researchers discovered this when they looked into the lack of reporting of information from "stalled drug" trials in cancer, cardiovascular and neurological diseases.

Two researchers win Humanity in Science prize for developing new antimalarial drug production methods

Prof. Dr. Peter H. Seeberger, a director at the Max Planck Institute of Colloids and Interfaces in Potsdam and a professor of chemistry at Freie Universität Berlin, and Prof. Dr.-Ing. Andreas Seidel-Morgenstern, a director at the Max Planck Institute for Dynamics of Complex Technical Systems in Magdeburg and a professor of chemical engineering at the Otto-von Guericke-University in Magdeburg, won the Humanity in Science prize for their groundbreaking work in developing new production methods for antimalarial drugs.

European scientists identify gene linked with certain types of early-onset epilepsy

Certain types of early-onset epilepsy are caused by previously unknown mutations of a potassium channel gene, KCNA2. The mutations disrupt the electrical balance in the brain in two ways. In some patients, the flow of potassium is greatly reduced; while in others, it is raised enormously. Both states can lead to hard-to-treat epileptic seizures. Mental and motor development can come to a stop, or even to regress.

Scientists find strong association between MAIT lymphocytes and metabolic dysfunctions

Scientists at Institut Cochin (CNRS/Inserm/Université Paris Descartes) and ICAN - Institute of Cardiometabolism And NutritionInserm/UPMC/AP-HP) have discovered that a class of inflammatory cells, MAIT lymphocytes1, is deregulated in patients suffering from type 2 diabetes and obesity.

Clinical trial examines uncertainty about when to give blood transfusions after cardiac surgery

New research has shown that patients having heart surgery do not benefit if doctors wait until a patient has become substantially anaemic before giving a transfusion.
