Wisconsin scientists grow critical nerve cells

... pave the way for novel treatments of degenerative diseases such as amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease. With healthy cells grown in the lab, scientists could, in theory, replace dying motor neurons to restore function and alleviate the symptoms of disease or injury. Much ...

Man and mouse share genome structures

...portant as changes in the genome itself in causing diseases such as cancer. This regulatory structure, called chromatin, is a key regulator of gene expression in healthy and diseased cells, Bernstein said. Chromatin is composed of DNA spooled around bundles of histone proteins, and resembles a chain of beads...

Genes In The Interferon System Important In Systemic Lupus Erythematosus

... behind the disease SLE, and maybe otherautoimmune diseases at the molecular level," says Professor LarsRönnblom. "Itis remarkable that by studying only eleven of the some 200 genes thatare seen as belonging to the interferon system, we were able toidentify two genes with such clear connection to SLE," says ...

Ecological destruction fuels emerging diseases

... linked to the emergence of new human and wildlife diseases such as West Nile Virus and avian flu. "The biodiversity crisis is not just about extinctions," says Dr. Brooks, whose pioneering parasite systematics research is supported by Science and Engineering Research Canada (NSERC). "In the past, when there...

Newly discovered virus linked to childhood lung disorders and Kawasaki disease

...avirus may account for someof the many respiratory diseases for which a causative agent isunidentified, and may have a role in Kawasaki disease, the most commoncause of acquired heart disease in children in developed countries. In the first of two studies, Jeffrey S. Kahn and co-workers at YaleUniversity use...

Inexpensive, mass-produced genes core of synthetic biology advances at UH

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 electrocardi...

Learning to fight an adversary that won't stay down

...avies, adding that doctors who deal with microbial diseases in hospitals must remain cautious about exposing the bacterial pathogens to the newest and most effective drugs so as to avoid overuse and the accompanying onset of resistance. "There are a relatively small number of antibiotics that have come out t...

Emory Eye Center Implants Its First Retinal Chips In Patients With Retinitis Pigmentosa

...in both eyes. It is a general term for a number of diseases that predominantly affect the photoreceptor layer or "light sensing" cells of the retina. Night blindness develops, usually in childhood, followed by loss of peripheral visual field, progressing over many years to tunnel vision and finally blindness....

Researchers reveal the infectious impact of salmon farms on wild salmon

...rom Princeton University who researches infectious diseases in wildlife. "We're seeing similar effects in Scotland, Norway, and Ireland; in each area parasite amplification on fish farms seems to increase disease levels in the local fish community. However previous studies have not shown nor quantified the di...
