Possible toxic damage from inhaled nanoparticles

A physicist and a medical researcher at the University of Leicester have received a grant of £100,000 from the Engineering and Physical Sciences Research Council to look at possible toxic damage from inhaled nanoparticles used for a range of everyday purposes.

Study provides insight into cellular defenses against genetic mutation

With their latest discovery, researchers have significantly advanced the understanding of how human cells protect themselves from constant and potentially destructive changes in gene expression.

Gene therapy used to successfully treat heart failure

University of Pittsburgh investigators have for the first time used gene therapy to successfully treat heart failure and other degenerative muscle problems in an animal model that is genetically susceptible to a human muscular dystrophy.

How cells use very slow biological flows to signal and organize

An EPFL (Ecole Polytechnique Federale de Lausanne) team led by professor Melody Swartz has demonstrated for the first time that the presence of very slow biological flows affects the extracellular environment in ways that are critical for tissue formation and cell migration.

Identification of gene in mosquitoes that helps them to fight off infection by the Plasmodium parasite

Researchers have identified a gene in mosquitoes that helps the insects to fight off infection by the Plasmodium parasite, which causes malaria in humans. Anopheles mosquitoes transmit the malaria parasite to nearly 550 million people worldwide each year with these cases resulting in more than 2 million deaths annually.

Ginseng shown to significantly offer protection from colds

According to new research people who take ginseng suffer from far fewer colds.

Maximum longevity inherited from the father

The parts of the genetic make-up that are thought to determine an individual’s maximum possible longevity, so-called telomeres, are inherited from the father but not the mother. This is shown by a research team at Umea University in the coming issue of the U.S. scientific journal Proceedings of the National Academy of Sciences.

FDA approves first transplant of fetal stem cells into human brains

The U.S. Food and Drug Administration has approved the first transplant of fetal stem cells into human brains, a procedure that if successful could pave the way to treating a host of neural disorders.

New treatments suggest that cancer is on the run!

People suffering from cancer will be encouraged by a cluster of recent reports on successful new treatments for several different forms of cancer.

Natural selection has played an important role in patterning the human genome

The most detailed analysis to date of how humans differ from one another at the DNA level shows strong evidence that natural selection has shaped the recent evolution of our species, according to researchers from Cornell University, Celera Genomics and Celera Diagnostics.

Researchers learn to rapidly rebuild immunity in immune-suppressed cancer patients

Patients with multiple myeloma suffer from a malignant proliferation of plasma cells in their bone marrow. The standard treatment for this form of cancer is high-dose chemotherapy and transplantation of one's own blood-producing adult stem cells; however, this aggressive treatment wipes out the mature immune-system cells of patients – leaving them vulnerable to infection.

Molecule P-glycoprotein (Pgp), may help reduce risk of Alzheimer's

A molecule that has long been an obstacle to cancer chemotherapy and drug treatments for brain disorders may soon become an ally in the fight against Alzheimer's disease, according to researchers at Washington University School of Medicine in St. Louis and the University of Rochester.

Zambia to try 'herbal remedy' as a treatment for HIV/AIDS

The United Nations paints a grim picture of the health situation in Zambia. One in every six adults in Zambia is living with HIV, life expectancy at birth is below 40 years and 630,000 children in Zambia are AIDS orphans.

Blocking macrophage migration inhibitory factor molecule might prevent the progression of multiple sclerosis

A new study suggests that a substance made by immune cells plays a key role in the progression of a disease in animals that closely mimics multiple sclerosis (MS). The findings further suggest that blocking the molecule, known as macrophage migration inhibitory factor (MIF) might prevent the progression of the disease.

When it comes to keeping clean, old fashioned soap and water may be best

Over the last decade the popularity of soaps and cleaning products claiming to have anti-bacterial properties has mushroomed as consumers are persuaded, by clever marketing, that they offer a defense against household illnesses.

Conjugated linoleic acid prevents inflammatory damage resulting from immune response

One of the isomers of conjugated linoleic acid, a group of fatty acids found in milk, is a natural regulator of the COX-2 protein, which plays a significant role in inflammatory disease such as arthritis and cancer, according to a study published by University of Wisconsin-Madison researchers.

Evidence is mounting to link toxoplasmosis with schizophrenia

Keep pet cats inside, stop feeding strays, cook meat sufficiently and reconsider the way the veterinary profession and public health agencies think - and teach - about the zoonotic pathogen Toxoplasma gondii.

Steroids and the chicken pox are a bad combination for children

Children who have been treated with steroids and are exposed to chicken pox tend to have a more severe case of the virus, according to pediatric oncologists at Brenner Children's Hospital, part of Wake Forest University Baptist Medical Center.

Discovery could lead to tests for the clinic or battlefield to diagnose ailments with just a few drops of blood

A way to detect fragments of broken brain cells that leak into the bloodstream may help doctors more quickly and precisely treat people with severe head injuries or brain diseases, say researchers at the University of Florida's McKnight Brain Institute.

Researchers shed light on a key molecular switch in T helper cells

Defects in immune system cells called T helper cells may lead to diseases characterized by a faulty inflammatory response such as autoimmunity and asthma. Understanding the molecular steps involved in how T helper cells mature may help researchers develop treatments for these diseases.
