National guidelines released for earwax removal
The American Academy of Otolaryngology - Head and Neck Surgery Foundation (AAO-HNSF) will issue the first comprehensive clinical guidelines to help health care practitioners identify patients with cerumen (commonly referred to as earwax) impaction. The guidelines emphasize evidence-based management... view more (2008-08-29)

Landmark studies assess risk of exposure to elevated levels of EMS confirm clear toxicity threshold
New data from studies presented at the XVII International AIDS Conference in Mexico City have provided unprecedented insight into the toxicity of an impurity called ethyl methanesulfonate (EMS). The formation of the EMS impurity is a potential by-product of the manufacturing of mesylate salts,... view more (2008-08-05)

New form of Alzheimer's disease discovered
According to Professor Matti Haltia, a new form of the hereditary disorder Alzheimer's disease, which paralyses the lower extremities of its victims, has been discovered in Finland. This disease has since also been discovered in many other countries. The disorder is caused by a new type of genetic... view more (2003-11-04)

Thyroid hormone, brain development, and behavior
Dr. Bjorn Vennstrom and colleagues in Spain and at the Karolinska Institute (Sweden) have identified novel neural functions of thyroid hormone (TH), revealing that it is required during discrete periods of brain development to confer "normal" behavior.   view more (2005-08-30)

Marathon mice elucidate little-known muscle type
Researchers report in the January issue of the journal Cell Metabolism, published by Cell Press, the discovery of a genetic "switch" that drives the formation of a poorly understood type of muscle. Moreover, they found, animals whose muscles were full of the so-called IIX fibers were able... view more (2007-01-03)

Lipids play important role in nervous system development
Blocking a signaling lipid can keep nerves from developing the arm-like extensions they need to wire the body and may even cause neurons to die, researchers have found.   view more (2005-10-25)

New 'molecular switch' protein protects the heart from major cardiovascular damage
It's just one little amino acid, but it makes all the difference in protecting the heart from the harmful effects of heart attack and cardiac failure. Researchers from the University of Michigan Medical School suggest this amino acid, called histidine, could be the key to a new therapy for... view more (2006-01-23)

HU Ph.D. student wins award for 'natural protection' to reduce spread of Alzheimer's disease
Although numerous drugs have been developed over the years to alleviate the symptoms of Alzheimer's disease, there is still no real cure to halt this progressive, neurodegenerative disorder that causes premature death of nerve cells in the deep brain nuclei, leading to dementia and death.   view more (2007-06-12)

Salt of the Earth
A yeast gene responsible for salt tolerance has successfully been used to grow tobacco in a salty environment lethal to most plants. Dr Janey Henderson and Professor Phil Harris from Coventry University inserted the halotolerance gene HAL1 from yeast into a tobacco plant. HAL1 has previously been... view more (2001-04-04)

Impaired clearance of amyloid-beta causes vascular damage in Alzheimer's disease
New research suggests that accumulation of amyloid-Œ≤ peptides in cerebral blood vessels, as opposed to the brain itself, may be a more important pathological mediator of Alzheimer's disease.   view more (2005-07-21)

Brain enzyme treatment relieves memory lapse in Alzheimer's mice
An enzyme that helps neurons rid themselves of excess or aberrant proteins is required for normal brain function.   view more (2006-08-25)

Antibody-altering protein found in developing B cells
In order for the B cells of the immune system to identify and fight disease pathogens, they produce a protein called activation-induced cytidine deaminase (AID).   view more (2007-07-20)

Adiponectin is a metabolic link between obesity and bone mineral density
Researchers at the University of Toronto, Faculty of Medicine, Toronto, Canada, have discovered that adiponectin, a protein secreted from adipocytes, is a metabolic link that can explain, in part, the known positive relationship between obesity and both bone mineral density and reduced... view more (2008-11-26)

Ecologists warn of the dangers of GM fish
The aquaculture industry will do increasing ecological damage around the world unless urgent action is taken by national and international policy makers, a new report by the British Ecological Society has warned. The report - written by experts from University College Cork, the University of... view more (2003-06-17)

Old leaves need to die in time or they will bring a plant down
In a study from the November issue of The American Naturalist, researchers Alex Boonman and co-workers from the Netherlands show that it is beneficial for plants growing in a dense stand to shed their oldest, lower leaves once these become shaded.   view more (2006-11-02)

Genetic vaccine promising against chronic hepatitis C
A potential vaccine candidate against chronic hepatitis C (HCV) infections is presented in a thesis from Karolinska Institutet. The new genetic vaccine can activate immune responses that are needed to clear HCV, a disease that today is difficult to treat effectively. The hepatitis C virus (HCV) is... view more (2004-06-07)

Remote control for human growth hormone gene expression
Researchers at the University of Pennsylvania School of Medicine recently discovered a novel mechanism that works over an extensive genomic distance and controls the expression of human growth hormone (hGH) in the pituitary gland.   view more (2006-08-14)

Dartmouth researchers find that arsenic triggers unique mechanism in rare leukemia
Dartmouth Medical School (DMS) researchers have identified a new way that arsenite, a form of arsenic, acts in treating a rare cancer known as APL, or acute promyelocytic leukemia. Their study is published in the Jan. 3 issue of the Journal of the National Cancer Institute.   view more (2007-01-09)

After a 40-year search, a hormone controlling iron metabolism in mammals is finally identified
Iron is vital for cells, because it catalyzes key enzyme reactions; it is also crucial for respiration, fixing atmospheric oxygen to hemoglobin in red blood cells. Iron deficiency can lead to severe anemia, with inadequate tissue oxygenation. An excess of iron is also toxic, as it facilitates the... view more (2002-04-03)

Scientists discover genetic key to growing hardier, more productive plants
A team of scientists led by University of Connecticut plant biologist Roberto Gaxiola has discovered an overlooked genetic key to generating plants that are more productive, more drought resistant and can grow in soils low in nutrients.   view more (2005-10-07)
