Birth defects: 8 million annually worldwide

...east 3.3 million children less than 5 years of age die annually because of serious birth defects, defined as any serious abnormality of structure or function. An estimated 3.2 million of those who survive may be mentally and physically disabled for life. Birth defects are a global problem, but their ...

Parents need to be educated about HPV vaccinations for daughters

...ear worldwide, and every year nearly 274,000 women die from the disease, with about 80% of these deaths occurring in developing countries where there is little or no access to cervical screening programmes.[1] "HPV vaccination has the potential to make a huge difference to women's lives, particularly in...

Canine cancer vaccine program shows early promise

...atment, 75 percent of dogs with oral melanoma will die within one year. But about 40 percent of dogs with a melanoma tumor present responded to a vaccine created from actual melanoma tumor cells. In about 12.5 percent of the treated dogs, the tumor completely disappeared. While the current results are ...

UCLA scientists find male gene in brain area targeted by Parkinson's

...ntrolling movement and coordination. As the cells die off, they produce less dopamine. This slows the delivery of messages from the brain to the rest of the body, leaving the person unable to initiate or control their physical movements. The condition eventually leads to paralysis. "For the first time,...

Marine mammals are on the frontline of failing ocean health

...that fish and other food sources - once thought to die too quickly to pass on brevetoxins ?can concentrate and carry the toxin long after an algal bloom. "This is surprising," he says. "We never suspected that there could be vectors like seagrass or fish." Many scientists believe algal blooms are likel...

U of MN researchers identify ataxia gene

...l structure to cells, will clarify how nerve cells die and may provide insight into other diseases, including amyotrophic lateral sclerosis (Lou Gehrig's disease) and Duchenne muscular dystrophy.The research will be published in the February print issue of Nature Genetics, and posted online Jan. 22, 2006...

CU, USDA team to curb two invasive, poisonous vines

...eir eggs on pale or black swallow-wort, the larvae die within three days. DiTommaso and his graduate students are investigating whether the plants release root chemicals that alter soil conditions. Preliminary findings suggest that communities of mycorrhizae -- soil fungi that help provide more nutrient...

Anthrax spores may survive water treatment

...e of how other waterborne pathogens may survive or die in drinking water systems, little is understood about the fate of anthrax spores in chlorinated water systems," says Jon Calomiris of the Air Force Research Laboratory at Aberdeen Proving Ground in Edgewood, Maryland, who conducted the study. Calom...

Gene therapy 'turns off' mutation linked to Parkinson's disease

... from the diseased dopamine-producing neurons that die in Parkinson's disease. Alpha-synuclein is abundant in structures known as Lewy bodies ?a diagnostic hallmark of Parkinson's disease. Research has shown that mutant forms of the alpha-synuclein gene, as well as too much alpha- synuclein protein, are...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

...ain, and that these cells gradually degenerate and die during the person's lifetime and cannot be replaced. This theory was disproved when researchers discovered that certain regions of the adult brain do in fact retain their ability to support and promote cell renewal (neurogenesis) throughout life, esp...

Cloned stem cells prove identical to fertilized stem cells

...gree of genetic abnormality. Most clones, in fact, die in utero or at birth. The few clones that make it into adulthood are often plagued by bizarre health complications. This is one reason why scientists generally believe that attempting to clone a human being is morally reprehensible. But are the clo...

Flu not the only germ threat this time of year

...estimated that 14,000 elderly and high-risk adults die annually from an RSV infection, and that the bug is responsible for more than 177,500 hospitalizations of adults each year. In addition, pediatricians have long known that the bug is a danger to small children, affecting hundreds of thousands of chil...

Common enzyme is a key player in DNA repair

...age, these bacteria are 1,000 times more likely to die than normal bacteria. Godoy is now an assistant professor of biology at Northeastern University in Boston. She and Jarosz also found that DinB can only repair G damage of a certain size. For example, they said, DinB cannot efficiently copy over a par...

In his new lab at Georgia, Docampo will continue to study the purification of polyphosphate present in platelets and on the enzyme...

Some like it hot: Worms at deep-sea vents favor a fiery 45-55°C

... of equally inhospitable environments are known to die fairly quickly under such conditions; in one previous study of desert fire ants, all died within one minute of exposure to a temperature of 55 degrees Celsius. Such ants will survive brief forays into similarly hot areas to obtain food, but do not ch...

The research, published online today in PLoS Genetics, shows how the target of the vaccines, called the polysaccharide capsule, has evolved and allows the researchers to determine functions of the genes involved. The polysaccharide capsu...
