Mosquito study shows new, faster way West Nile can spread

...ictions that it would progress more slowly or even die out. In the conventional understanding of West Nile transmission, mosquitoes acquire the virus when they bite birds with high levels of virus (or "high viremia.") in their blood. Those levels are reached several days after the birds are initially in...

Scientists find a maturity gene in fly

...e journal Cell. The flies are abnormally small and die as they enter adulthood, sometimes when their heads fail to emerge from their bodies. "We identified a gene that is needed for the animal to progress through normal juvenile development to maturation," says University of Utah geneticist Carl Thummel...

Quick identification needed to save Florida's citrus industry from devastating disease

...he infected trees to yellow, decline, and possibly die within a few years. The bacterium is spread by an insect, the citrus psyllid. "Although there is no cure for citrus greening, it is vital that plant pathologists work with growers to quickly identify the disease and its insect hosts," said Ronald Br...

UT Southwestern researchers discover master switch in cell death

...ocess manifests itself in cancers when cells don’t die when they’re supposed to. The key to the researchers?finding was the interaction between the Mule enzyme and a major player in cell death, the protein Mcl-1. Dr. Wang said that while there are many possible routes a cell may take toward apoptosis, t...

OHSU researchers discover potential mechanism to repair brain damage linked to Multiple Sclerosis

...scar tissue in the brains of premature infants who die during intensive care also produces HA. We believe the HA may also prevent the production of myelin-producing cells and be related to the motor impairment seen in CP. My hope is that this work will benefit a wide range of patients from premature infa...

Drug resistant avian influenza viruses more common in Southeast Asia than North America

...sensitive strains. In addition, the infected birds die so rapidly there is no time for the virus to acquire a large number of mutations, among which could be changes in the M2 protein. Therefore, the high rate of M2 mutations in China probably arises from some human activity that encourages selection of ...

UQ scientists break new ground in fight against infection & chronic disease

...gers were among the agents that caused patients to die from acute infections like bird flu and to acquire chronic inflammatory diseases such as arthritis and inflammatory bowel disease. They are also behind the muscle wasting experienced by patients with cancer. Chronic inflammatory disorders are a sub...

Researcher says flu responders can learn from 1918 epidemic

... the Board of Health, saw roughly 13,000 residents die as the flu swept through the inner city neighborhoods. It represented, Higgins said, the worst case scenario, with dead bodies piling up outside of police stations and others dumped into trench graves. "Obviously, not every city had the same experi...

Anthrax stops body from fighting back, study shows

...versity of Michigan Medical School. "A person can die before they know they are terribly sick at all," Hanna said. Symptoms of inhalation anthrax resemble the common cold and progress to breathing problems, shock and often death, according to the CDC. But in the 2001 attacks, only half the 10 people w...

Other affected species eventually decline to the point where the dead branches pose a safety risk and the tree must be removed. According to Gould, current management options o...

In contrast, if all of Arizona's cotton was Bt cotton, only pink bollworm caterpillars that were resistant to the Bt toxin would survive. If resistant pink bollworm moths mated with each other, their offspring would be resis...

A new link between stem cells and tumors

... themselves in new tissues. Specialized cells may die through age or injuries, so the body keeps stocks of stem cells on hand to generate replacements. Usually the stem cell divides into two types: one that is just like the parent, which is kept to maintain the stock, and another that differentiates. Th...

Restoring silenced suppressor gene kills lung-cancer cells

A little telomerase isn't enough

...ines can't divide as many times as they should and die early. Because sperm and egg arise from stem cells, too, their telomeres gradually shorten, and each successive generation starts out with chromosomes whose telomeres are even shorter than their parents, the researchers report. The failure of telom...

Immuno-compromised patients such as transplantation, AIDS and steroid treatment patients are also frequently affected with life-threatening Aspergillus pneumonia and sinusitis. Fortunately, ...

Therefore, an early acting treatment would help reduce the high rates of disability and death. "Previous studies have found that Streptococcus bacteria from inf...
