Study: Cigarette smoking linked to mucus overproduction in patients with chronic bronchitis

Cigarette smoking has been linked with overproduction of mucus associated with chronic bronchitis, according to a study conducted by researchers in New Mexico. The study indicates cigarette smoke suppresses a protein that causes the natural death of mucus-producing cells in the airways of bronchitis patients.

Metallic copper surfaces kill bacteria on contact

Metallic copper surfaces kill microbes on contact, decimating their populations, according to a paper in the February 2011 issue of the journal Applied and Environmental Microbiology. They do so literally in minutes, by causing massive membrane damage after about a minute's exposure, says the study's corresponding author, Gregor Grass of the University of Nebraska, Lincoln. This is the first study to demonstrate this mechanism of bacteriocide.

Researchers develop new pneumococcal vaccine through novel discovery approach

Pneumococcus accounts for as much as 11 percent of mortality in young children worldwide. While successful vaccines like Prevnar exist, they are expensive and only work against specific pneumococcal strains, with the risk of becoming less effective as new strains emerge.

Continued smoking during radiation treatment for head and neck cancer affects prognosis

Smokers who continue to smoke while undergoing radiation treatments for head and neck cancer fare significantly worse than those who quit smoking before therapy, according to a study in the February issue of the International Journal of Radiation Oncology•Biology•Physics, an official journal of the American Society for Radiation Oncology (ASTRO).

Experts say signs and treatment of bacterial infection often misunderstood

According to the Canadian Foundation for Infectious Diseases, antibiotics are the second most frequently prescribed class of drugs - second only to pain relievers. Yet most people don't know the difference between a true bacterial infection, like chronic bronchitis that can be treated with antibiotics — and viruses like the common cold, which cannot.

First evidence of neurotrophic factors improving status of degenerating dopamine neurons in Parkinson's brains

Ceregene, Inc., a biopharmaceutical company, reported today that its scientists and collaborators have published new experimental findings in support of its Parkinson's disease program which appeared as the lead article in the current issue of Movement Disorders. The publication reports the first evidence that gene transfer can provide targeted expression of a neurotrophic factor, i.e., neurturin or NRTN, intended to restore and preserve dying neurons.

Deactivation of CRTC1 protein increases lifespan

Substantial evidence suggests that lifespan is increased if an organism restricts its daily calorie intake, a spartan regime that some say works by just making life seem longer. A team of scientists from the Salk Institute of Biological Studies has discovered a molecular switch flipped by hunger that could not only make longevity more appetizing but identify drug targets for patients with aging-related diseases such as type II diabetes or cancer.

Muscle, aptly enough, is born of cellular bullying, and not mutual consent

In fact, according to new research from Johns Hopkins, the fusion of muscle cells is a power struggle that involves a smaller mobile antagonist that points at, pokes and finally pushes into its larger, stationary partner using a newly identified finger-like projection.

Molecular explanation to higher tendency for autism among males

George Washington University researcher, Dr. Valerie Hu, Professor of Biochemistry and Molecular Biology, and her team at the School of Medicine and Health Sciences, have found that male and female sex hormones regulate expression of an important gene in neuronal cell culture through a mechanism that could explain not only higher levels of testosterone observed in some individuals with autism, but also why males have a higher incidence of autism than females.

Impaired brain insulin action may worsen type 2 diabetes

Researchers from Mount Sinai School of Medicine have discovered a novel function of brain insulin, indicating that impaired brain insulin action may be the cause of the unrestrained lipolysis that initiates and worsens type 2 diabetes in humans. The research is published this month in the journal Cell Metabolism.
