Protein discovery could unlock the secret to better TB treatment

... cent show multidrug resistance. Left untreated, a person with infectious TB of the lungs infects around 10 to 15 people every year. In a study published on 1st March 2005 in Nature Structural & Molecular Biology, a combined team discovered the structure of a protein known as resuscitation promoting fa...

Poor prenatal nutrition permanently damages function of insulin-producing cells in the pancreas

... understand that prenatal undernourishment makes a person permanently at higher risk for developing diabetes, so prenatal care is important," Dr. Patti said. "Moreover, if someone was born with low weight, they need to pay special attention to prevention tactics, including exercise and weight control to min...

Neuronal 'traffic jam' marks early Alzheimer's disease

...achinery in their neurons breaks down with age. "A person could have a predisposition to the disease, or it could just be that as time progresses, one person could by chance accumulate these blockages more than another," said Goldstein. "And randomly, some p...

Computers to be used to find blueprint for new influenza drug

...ur throats that the flu virus first attacks when a person becomes infected. The flu virus would be deceived into attacking the drug, called an inhibitor, instead of the cells. The three-year project will be largely carried out by examining the behaviour of atoms of the influenza virus which attack cells, a...

HIV Patients May Be at Risk of Heart Problems When Taking Protease Inhibitor Drugs

...zes in various diseases and conditions that make a person vulnerable to sudden death by a ventricular arrhythmia. There are several specific actions physicians can take to use this new information wisely, Drs. Ackerman and Badley say. The first is to screen by electrocardiogram for heart effects in vulnera...

U-M scientist to talk about tissue engineering at AAAS

...ts is more complex. Regenerating the jaw bone of a person undergoing radiation therapy for cancer means managing the constant bacteria bath of a human mouth as well as compensating for the damage of radiation. "It's not just a question of whether we can make new tissue in a perfect condition. Now we're mim...

Gene therapy converts dead bone graft to new, living tissue

... has excess calcium. In an average year, a healthy person may remove and rebuild 10 percent of his or her bone structure. This process of teardown and rebuilding is triggered in the dead bone when Schwarz paints it with the genetically modified virus. New blood vessels begin to grow around and into the bon...

Novel Therapy Tested in Mice Could Chase Away Cat Allergies

...ry eyes, and sometimes asthma. When a cat-allergic person touches or inhales a protein found in cat saliva or dander (small scales from its skin or hair), key immune system cells respond by spewing out histamine. Allergy experts estimate that 14 percent of children 6 to 19 years old are allergic to cats. T...

For example, a person testing positive for HIV (human immunodeficiency virus, or the AIDS virus) using one of these tests may not be infected with HIV, or, worse, someone infected with HIV may test negative and not seek medical treatment or spread the virus to others. Th...

NJIT Presidential Award winner takes stem cell research another step

...and another proving that stem cells taken from one person can be successfully implanted into another. A list of conditions for which stem-cell treatment holds promise grows almost daily: It now includes Parkinson's, diabetes, Alzheimer's, cancer and traumatic brain injury.

Implanted Devices Detect High-Risk Heart Failure Patients

...-half times more likely to die after one year. "A person with normal heart rate variable would have a very wide footprint, while those with sick hearts would have a narrow footprint that represents the reduced variance in heart rate response," Gilliam explained. "These footprints provide us with an unbiase...

International HapMap consortium expands mapping effort

For any given disease, such as type II diabetes or coronary artery disease, researchers can use the HapMap to compare the genetic variation patterns of a group of people known to have the dis...

Chemists identify immune system mechanism for methamphetamine binges

"The device might work with me, but if you don't have enough of the reactive species in your blood, then it may not generate adequate nitric oxide levels and it may not prevent clotting," said Meyerhoff. To get at these questions, the res...

Gene Therapy Cures Inherited Liver Disease In Rats

...ajjar syndrome is currently treated by placing the person under special UV lights. It is an unwieldy and time-consuming treatment. While Lee does not think that cure would be possible in all adults with this technique, he does think it poses a real promise for long-term alleviations of the toxic symptoms o...
