SSRI antidepressants may also affect human immune system

Drugs that treat depression by manipulating the neurotransmitter serotonin in the brain may also affect the user's immune system in ways that are not yet understood, say scientists from Georgetown University Medical Center and a Canadian research institute.

Novel compound stops brain cell degeneration in Alzheimer's disease

Drug discovery researchers at Northwestern University have developed a novel orally administered compound specifically targeted to suppress brain cell inflammation and neuron loss associated with Alzheimer's disease.

Identification of gene in childhood kidney disease

An international research collaboration led by Mayo Clinic has identified a new gene involved in causing the inherited kidney disorder, Meckel-Gruber syndrome (MKS). Children with MKS have central nervous system deformities as well as abnormal cysts in their kidneys, and usually die shortly after birth.

Tomato juice keeps emphysema from developing in new animal model of degenerative disease

Feeding tomato juice to mice kept them from developing emphysema after cigarette smoke exposure that was long enough to induce emphysema in a control group, Japanese researchers report in February issue of the American Journal of Physiology-Lung Cellular and Molecular Physiology.

Polyphosphate speeds blood clotting and helps clots last longer

A serendipitous comparison prompted by an old scientific image and involving an ancient but understudied molecule may lead to a new treatment strategy for injuries or illnesses in which blood clotting is paramount to survival.

Women more vulnerable to effects of alcohol use

Although women consume less alcohol than men, they are more susceptible to some of the negative medical consequences of alcohol use, such as cirrhosis of the liver, cardiac disease, and cognitive impairments.

Gene discovery may prevent craniofacial birth defects

Craniofacial researchers have developed an animal model that explains how skull malformations occur and how they might be prevented.

Study to look for links between the nervous system and fatal heart rhythm

Finding out why seemingly healthy people experience ventricular fibrillation, a fatal irregular heart rhythm, could eventually lead to better methods of early detection, according to a Medical College of Georgia researcher.

Long term air pollution exposure leads to acceleration of atherosclerosis and vascular inflammation

Findings indicate a significant independent association between exposure to long term air pollution and the acceleration of atherosclerosis and vascular inflammation in an animal model.

Liver plays crucial role in iron metabolism

A new study in the December Cell Metabolism reveals an unexpected connection between a tumor suppressor gene in the liver and the normally careful control over the amount of iron absorbed from the diet.

Aldosterone shows promise as stroke treatment

A bi-polar hormone that can contribute to strokes and minimize their damage is emerging as a therapeutic target in the battle against these brain attacks, researchers say.

Fullerenes can help fend off damage to normal tissue from radiation

Using transparent zebrafish embryos, researchers at Jefferson Medical College have shown that a microscopic nanoparticle can help fend off damage to normal tissue from radiation.

Darbepoietin alpha may provide cardiac protection 24 hours after heart attack

A drug has been shown to provide some protection to the heart from injury even if given as much as 24 hours after a heart attack, Jefferson Medical College researchers report.

Sperm stem cells research provides exciting findings

New experiments that prevented rat sperm stem cells from changing permanently into sperm have brought researchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body.

Drug pravastatin may provide a previously unknown cardiovascular benefit

The drug pravastatin, which is used widely to decrease high cholesterol, may provide a previously unknown cardiovascular benefit in addition to lowering lipids.

Tryptophan metabolites play an important role in the immune system

Tryptophan is the source of Thanksgiving legend and grist for a "Seinfeld" episode, but it's not the chemical that you'd expect to find in Lawrence Steinman's lab.

First steps taken to treat human hereditary blindness

A team led by Krzysztof Palczewski, Ph.D., chair of pharmacology at the Case Western Reserve University School of Medicine, has taken the first steps in treating an eye disease causing irreversible congenital blindness in millions of people worldwide by successfully testing two new treatments in mice.

Protein called CHIP helps untangle protein misfolding in brain disease

Keeping the body and mind healthy depends on keeping cells healthy and functioning. This means that cells need a very robust quality-control system to repair or remove damaged or misshapen proteins. Protein handling is especially important in neurons because damage or death of brain cells causes neurological disease.

Dendritic cells tricked into action against cancer

A new type of immunotherapy in which dendritic cells are tricked into action against cancer when they are exposed to harmless pieces of viruses and bacteria is described in the November issue of Cancer Research.
