Live vaccines more effective against horse herpes virus

... have been more reports of the severe neurological disorder associated with equine herpes. "It appears we are seeing it with more frequency and in a larger number of horses," he said. Previous studies on horses have found the inactivated vaccines are not very effective in lowering equine virus levels in the ...

Genetic defects give the immune system the green light to attack the pancreas

...ife, they must get insulin through injections. The disorder can emerge in childhood, adolescence and even appear in adulthood, but the genetic stage is set beforehand. T-cells play a key role. They are part of the highly complex array of immune cells that normally work together to fight invaders such as bact...

Mystery Blood Vessel Disorder Implicated In 'Mini' Strokes

...aortic aneurysm reveal new evidence that links the disorder with small vessel disease, a significant cause of lacunar or "mini" strokes that can damage small areas of the brain. Depending on which area of the brain is affected, the strokes can impair functions such as movement, physical control of speech, or...

Infants With Rare Genetic Disease Saved by Cord Blood Stem Cells

Children with a fatal genetic disorder called Krabbe disease can be saved and their brain development preserved if they receive stem cells from umbilical cord blood before symptoms of the disease develop, according to a study published in the May 19, 2005, issue of the New England Journal...

Alzheimer's cognitive decline slowed

...eature of Alzheimer's disease, a progressive brain disorder affecting memory, learning, attention and other cognitive processes. "If validated in further clinical trials, this would represent a substantially more effective therapy than current treatments for Alzheimer's disease," said Mark Tuszynski, M.D., P...

Light therapy may combat fungal infections, new evidence suggests

... used to repigment skin affected by the autoimmune disorder vitiligo. The findings also have important implications for understanding early fungal evolution, Heitman and study lead author Alexander Idnurm, Ph.D., reported in a forthcoming issue of Public Library of Science Biology, published online March 15,...

Potential treatments for neurofibromatosis

...nd ethnicities. It is the most common neurological disorder caused by a single gene. Some NF 1 mutations are inherited, but the NF1 gene is so large that many mutations occur spontaneously rather than being passed from parent to child. Everyone has two copies of the NF 1 gene, which produces a protein called...

The very unexpected life and death of a leukemic cell

...lenges the dogma that CLL is a purely accumulative disorder where leukemic cells accumulate because they cannot die. Clearly CLL is a disease in which there is a dynamic interplay between rates of cell division and cell death. The data could enable physicians to predict disease progression. ### In vivo mea...

Beyond lithium for bipolar disorder

...in weight. However, better treatments for bipolar disorder depend on a better understanding of the still-mysterious mechanism by which lithium damps the highs and lows of the disorder. Now, researchers led by Philip Brandish of Merck & Co., Inc., and Edward Scolnick of the Broad Institute (formerly of Me...

Octopuses occasionally stroll around on two arms, UC Berkeley biologists report

...called Eda, originally named after a human genetic disorder associated with the ectodysplasin pathway, an important part of the embryonic development process. The human disorder, one of the earliest ones studied, is called ectodermal dysplasia. "It's a famous old syndrome," Kingsley said. "Charles Darwin tal...

Researchers trace evolution to relatively simple genetic changes

The human disorder, one of the earliest ones studied, is called ectodermal dysplasia. "It's a famous old syndrome," Kingsley said. "Charles Darwin tal...

Muscle-targeted gene therapy reverses rare muscular dystrophy in mice

...l Center. Infants born with the inherited muscular disorder called Pompe disease usually die before they reach the age of two. The researchers also said their approach of targeting corrective genes to muscles may have application in treating other muscular dystrophies. Patients with Pompe disease have a defe...

A gene's first 'kiss' sets off that affair known as puberty

... called GPR54 is defective in children with a rare disorder that inhibits puberty's onset. To better understand what role GPR54 plays in the initiation of puberty, as well as learn about KiSS-1, which in earlier rodent studies had been identified as a molecule that activates a signal receptor of GPR54, the re...
