Saving salivary glands from the collateral damage of radiation therapy
Researchers have shown that targeted overexpression of heat shock protein 25 prevents radiation-induced damage to salivary glands, a common consequence of treatment for head and neck cancer.   view more (2006-10-30)

Woven scaffolds could improve cartilage repair
Using a unique weaving machine of their design, Duke University Medical Center researchers have created a three-dimensional fabric "scaffold" that could greatly improve the ability of physicians to repair damaged joints with the patient's own stem cells.   view more (2007-02-07)

A molecular map for aging in mice
Researchers at the National Institute of Aging and Stanford University have used gene arrays to identify genes whose activity changes with age in 16 different mouse tissues.   view more (2007-11-29)

Precision biochemistry tracks DNA damage in fish
Like coal-mine canaries, fish DNA can serve as a measure of the biological impact of water and sediment pollution-or pollution clean-up.   view more (2006-05-15)

£250,000 for clinical trials of functional strength training for the lower limb
The University of Manchester and St George's Hospital Medical School, in collaboration with Manchester Metropolitan University, have been awarded £250,000 by the PPP Foundation to carry out clinical pilot studies into functional strength training of lower limbs in patients who have suffered a stroke. As a cure for a stroke is not yet on the... view more... (2003-01-22)

Exposure to alkaline substances can result in damaged teeth
It has long been known that acids can erode tooth enamel but a new Swedish study from the Sahlgrenska Academy at the University of Gothenburg shows that strong alkaline substances can damage teeth too - substances with high pH values can destroy parts of the organic content of the tooth, leaving the enamel more vulnerable.    view more (2009-10-28)

p90RSK: A new therapeutic target for liver fibrosis?
Cirrhosis is a world wide, bad prognosis liver disease and characterized by excessive collagen deposition and liver function damage.   view more (2009-05-13)

New approach allows closer look at smoker lungs
Aided by a powerful imaging technique, scientists have discovered they can detect smoking-related lung damage in healthy smokers who otherwise display none of the telltale signs of tobacco use.   view more (2006-05-31)

A new way to look at lung cancer and tobacco carcinogens
Two types of cancer-causing agents in cigarettes-a nicotine-derived chemical and polycyclic aromatic hydrocarbons (PAHs) are the main culprits in lung cancer. Exposure to tobacco smoke - both mainstream and second-hand - is a leading cause of cancer death in the United States.   view more (2008-05-29)

Mixing large doses of both acetaminophen painkiller and caffeine may increase risk of liver damage
Consuming large amounts of caffeine while taking acetaminophen, one of the most widely used painkillers in the United States, could potentially cause liver damage, according to a preliminary laboratory study reported in the Oct. 15 print issue of ACS' Chemical Research in Toxicology, a monthly journal.   view more (2007-09-26)

New study finds how cells with damaged DNA alert the immune system
Research led by biologists at the University of California, Berkeley, has found that damage to a cell's DNA sets off a chain reaction that leads to the increased expression of a marker recognized by the body's immune system.   view more (2005-07-05)

Change policy: Giving steroids to children with meningitis can reduce hearing loss and lower the incidence of long-term brain damage and can save lives in both children and adults with meningitis
Research News in the Cochrane Database of Systematic Reviews Antibiotics are essential and life-saving in the treatment of bacterial meningitis, but for years doctors have debated whether to give corticosteroids at the same time. The inflammation caused by meningitis can actually be made worse by antibiotics in the short term, as the bacteria... view more... (2003-09-23)

Resuscitation technique after brain injury may do more harm than good
The current standard practice of giving infants and children 100 percent oxygen to prevent brain damage caused by oxygen deprivation may actually inflict additional harm, researchers at UT Southwestern Medical Center have found.   view more (2008-07-01)

New groundbreaking treatment for oxygen-deprived newborns
Until now immediate cooling of the newborn infant was the only treatment that could possibly prevent brain damage following oxygen deprivation during delivery.   view more (2009-08-11)

DNA repair mechanisms are concentrated in the active parts of the genome
Less than 10% of the human genome contains coded information in the form of genes. The 30,000-40,000 genes in the genome are found grouped in discrete regions of the chromosomes. Chemical agents and radiation habitually cause a large variety of injuries to the DNA which interferes in many cell processes, like transcription and replication, and... view more... (2002-10-01)

Evidence of rapid evolution is found at the tips of chromosomes
In terms of their telomeres, mice are more complicated than humans. That's the finding from a recent Rockefeller University study, which shows that mice have two proteins working together to do the job of a single protein in human cells.   view more (2006-08-02)

Aetiology of congenital heart disease explained
Researchers at Karolinska Institutet have identified the mechanisms behind the serious, congenital heart condition that can sometimes develop in children of women with a rheumatic disease.   view more (2005-02-07)
