An 'elegant' idea proves its worth 25 years later

...o says early and accurate detection can now assure prompt treatment. "We’re teaching all medical students at Hopkins to consider hyperammonemia and immediately do blood tests when they see a combative, lethargic or comatose newborn or child," she says. "The longer the hyperammonemia lasts, the higher the...

Anthrax attack posed greater potential threat than thought

...ilable online. On the other hand, the study shows, prompt intervention with antibiotics and vaccination appeared to be highly effective against the disease. In October of 2001, a letter containing spores of Bacillus anthracis, the bacterium that causes the deadly disease anthrax, was opened in Daschle's of...

Scientists unlock mystery of embryonic stem cell signaling pathway

...tem cells with the necessary chemical signals that prompt them to stay undifferentiated and to continue dividing over and over. Still, growing human embryonic stem cells on a layer of mouse fibroblasts has never made much sense to the scientists forced to do just that. “Stem cells that grow on feeders ar...

Meeting the ethanol challenge: Scientists use supercomputer to target cellulose bottleneck

... an available chain, the cellulose itself seems to prompt a change in the shape of the enzyme complex so that it can straddle the broken end of the cellulose chain. This gives the enzyme a crucial foothold to begin the process of digesting or "unzipping" the cellulose into sugar molecules. To the scient...

Mass vaccination unnecessary in the event of a large bioterrorist US smallpox attack

...S. government policy of post-release surveillance, prompt containment of victims and vaccination of hospital workers and close contacts would be sufficient to thwart an epidemic, according to lead author Ira M. Longini Jr., Ph.D., a world leader in using mathematical and statistical methods to study the nat...

Tiny bones rewrite textbooks

...l but remarkable fossils found in New Zealand will prompt a major rewrite of prehistory textbooks, showing for the first time that the so-called "land of birds" was once home to mammals as well. The tiny fossilised bones - part of a jaw and a leg - belonged to a unique, mouse-sized land animal unlike any o...

Malaria vaccine prompts victims' immune system to eliminate parasite from mosquitoes

.... The vaccine, so far tested only in mice, would prompt the immune system of a person who receives it to eliminate the parasite from the digestive tract of a malaria-carrying mosquito, after the mosquito has fed upon the blood of the vaccinated individual. The vaccine would not prevent or limit malarial ...

High hourly air pollution levels more than double stroke risk

...ay in the blood for up to an hour. Their findings prompt the authors to suggest that preventive measures should be based on average hourly measures rather than just average daily measures alone. ...

Dopamine drug leads to new neurons and recovery of function in rat model of Parkinson's

...the symptoms of PD, they have not been designed to prompt development of new neurons, he adds. Altering how the current drugs work or developing new compounds to enhance neurogenesis could provide an entirely new avenue for treating this disease. "These findings are very exciting for several reasons. Bei...

Hopkins scientists show hallucinogen in mushrooms creates universal 'mystical' experience

...centuries. The resulting experiences apparently prompt positive changes in behavior and attitude that last several months, at least. The agent, a plant alkaloid called psilocybin, mimics the effect of serotonin on brain receptors-as do some other hallucinogens-but precisely where in the brain and in w...

Researchers find 'secret weapon' used by SARS virus

...he breakdown of biochemical messages that normally prompt the production of a protein critical to defending the body against viruses. "The SARS nsp1 protein degrades the messenger RNA instructions sent from DNA to make interferon beta, which is crucial to host immunity," said UTMB professor of microbiolo...

New strategy rapidly identifies cancer targets

...lthy cells, they help form a chain of signals that prompt normal cell growth and division. Sometimes, though, a tyrosine kinase gets stuck in an "on" position, driving out-of-control cell division and, ultimately, cancer. This potentially devastating kinase activation carries a calling card in the form of a...

Radiation-killed bacteria vaccine induces broad immune response in mice

...al pathogens evidently retain characteristics that prompt the immune system to mount a full-fledged defense," says Dr. Datta, the study's lead author. "In this respect, irradiated pathogens more closely mimic the body's response to a live, attenuated vaccine." Finally, the scientists found that mice ...

A switch between life and death

...ppo signaling pathway, and higher levels of bantam prompt more cell division. "Bantam is an unusual type of RNA molecule," Thompson says. "Normally, RNAs go on to make protein, but bantam is different. Its job is to regulate other RNAs by attaching itself to them; the result is that they block their expres...

New vaccine for condition that kills 500,000 children a year

.... emergency rooms. In the developing world, where prompt hospitalization and effective treatment may not be available, rotavirus kills half a million infants a year, about one child each minute. Matson, widely regarded as one of the nation's leading rotavirus researchers, has studied the virus for over two...

Mice with glowing hearts shed light on how hearts develop

The researchers have also transplanted cells from the mice with glowing hearts into normal mice to see whether the transplanted cells function normally within the host heart, which could offer insights for heart repair...

One in 14 men having a heart attack drive themselves to hospital

The team's previous paper, published in the Journal of Advanced Nursing in September 2005, also identified the need for greater awareness by healthcare staff of the risks women face. It reported that it took 54 minutes longer for women ...

Wisconsin scientists find a way to make human collagen in the lab

...gen because the material now gleaned from cows can prompt an unwanted immune response in patients and it can harbor animal pathogens that might infect humans. The Wisconsin team discovered a way to make the long, slender collagen molecules, in essence, by having the protein assemble itself. What was requir...

Commonly used antidepressants may also affect human immune system

...coupling between the antigens and the T-cells will prompt the T-cells to divide and expand in population, triggering an immune response designed to destroy the invader. This process may take hours. What the Georgetown researchers found, however, is that dendritic cells -- the most powerful of the antigen-p...
