Congenital rubella syndrome nearly eradicated in the US

...tive vaccine introduced in the 1970s has helped in eliminating transmission of rubella from expectant mothers to their unborn babies. "Effectively, congenital rubella syndrome has been nearly eradicated from the United States," according to the statement. There were fewer than 10 cases or rubella reported in t...

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

...rted. Rotateq also proved to be effective, nearly eliminating serious rotavirus-related gastroenteritis. The vaccine reduced rotavirus-related hospital admissions by 96 percent. In addition, RotaTeq reduced rotavirus-related emergency rooms visits by 94 percent, and doctor's office visits by 86 percent. "The p...

Nearly half of people who need cholesterol treatment don't get it

...treatment and control of cholesterol disorders and eliminating treatment disparities." The data came from the Multi-Ethnic Study of Atherosclerosis (MESA), a population-based study of 6,814 men and women who had no known cardiovascular disease. Caucasian, Hispanic, Chinese and African-American participant were ...

Chemical guidance of T cells leads to immunologic memory and long-term immunity

...mportant because their activation is essential for eliminating infected cells and for providing, together with antibodies, long-lasting protection following vaccinations," says NIAID Director Anthony S. Fauci, M.D. The body contains hundreds of millions of CD8+ T cells, but only a tiny fraction of them become a...

Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...atients unrelated to the donor, without rejection, eliminating the need for donor matching and recipient immune suppression. Once transplanted, the cells promote healing of damaged or diseased tissues. Research has demonstrated that mesenchymal stem cells follow inflammatory signals or "home" to sites of injury...

BiovaxID?yields 89 percent survival in patients with aggressive non-Hodgkins

...umber of hematological cancers that are treated by eliminating diseased B-cells." Biovest is now enrolling patients in a pivotal Phase 3 trial to test BiovaxID against follicular non-Hodgkin's lymphoma (NHL). Follicular NHL is an indolent (slow-growing) form of lymphoma not considered curable with existing the...

Master genetic switch found for chronic pain

...experiments with mice, researchers have found that eliminating what appears to be a master genetic switch for the development of pain-sensing neurons knocks out the animals' response to "neuropathic pain." Such pain is abnormal pain that outlasts the injury and is associated with nerve and/or central nervous sys...

New Rotavirus vaccine joins routine infant immunization schedule

...It brings us a step closer to our ultimate goal of eliminating childhood disease." Nearly every child experiences infection with rotavirus, usually as gastroenteritis. In the United States, children under age five experience an estimated 2.7 million episodes of rotavirus gastroenteritis each year, resulting in...

Technique offers new view of dynamic biological landscape

...vidually. Many genes' activity could be reduced by eliminating them entirely, but for the subset of genes that are essential for yeast growth -- whose complete deletion would kill the cell -- the researchers invented a high throughput technique to manipulate the half-life of their messenger RNA (mRNA). Since mRN...

Brainstem blocks pain to protect key behaviors

...nt protective behaviors, but eating, drinking, and eliminating wastes are absolutely essential," said study author Peggy Mason, Ph.D., professor in the department of neurobiology, pharmacology and physiology (NPP) at the University of Chicago. "What we found was a very effective system that lets these animals f...

Sperm stem cells closer to being like embryonic stem cells

... ?cystic fibrosis, for example ?by identifying and eliminating in culture a man's sperm stem cells that carry the gene. Dr. Garbers said that a renewable source of cultured sperm stem cells, rat or human, also could be used to test for male-directed contraceptives, and a company is already interested in this p...

An essential regulator of body weight revealed

... bottle containing its liquid diet. The effects of eliminating NPY/AgRP neurons in adult mice were dramatic. After treatment with diphtheria toxin, the animals began to eat less and less; by the fifth day, they had stopped eating entirely. Within 6-8 days, they had lost 20 percent of their body weight. Interest...

Female butterflies go for sparkle -- not size -- when choosing to mate

...pupil on the dorsal side with black paint, thereby eliminating the pupil, these males were much less desirable to females by a ratio of two to one, demonstrating clearly that females preferred the presence of the white pupil. However, a large white pupil, about twice the diameter of a natural pupil, also was no...

Researchers find how some antibiotics kill bacteria

...s stomach ulcers; and even some parasitic worms by eliminating the symbiotic bacteria parasites depend on. "It's the kind of drug the pharmaceutical business wants to produce," Artsimovitch said. "They're looking for the broadest range of antibiotics possible. Rifamycins would be ideal drugs if we could figure ...

Progress on HIV/AIDS significant but insufficient

...g up programmes for children at risk, including by eliminating the cost of schooling and broadening nutritional programmes in schools, and strengthening prevention of mother-to-child transmission. In the round table concerning human rights with an emphasis on gender, it was stressed that human rights violations...

Gene loss accelerates aging

...dy how the p63 gene works, we devised a system for eliminating it from adult mouse tissues. What struck us right away was that these p63 deficient mice were aging prematurely," says Alea Mills of Cold Spring Harbor laboratory, who led the research. Mice that are born without the p63 gene do not survive. Therefo...

Ants, not evil spirits, create devil's gardens in the Amazon rainforest, study finds

...lants also benefit by increasing their biomass and eliminating the competition, says co-author Michael J. Greene, a former Sanford postdoctoral fellow, now assistant professor of biology at the University of Colorado-Denver. "This work is a truly remarkable example of how effectively ants can manipulate their en...

AACR Favors 'full spectrum of stem cell research biology'

...nd other malignant tumors, raising the prospect of eliminating tumor recurrence following initial treatment and developing cancer therapies that are truly curative. # Embryonic stem cells' ability spontaneously to form tumors should not hinder the progress of stem cell research, since these cells will be used o...

Molecular miners find pain relief drugs from the sea

... ineffective. The great potential of ACV1 is that eliminating neuropathic pain is where it works best. BACKGROUND Associate Professor Livett and his colleagues first discovered ACV1 in 2003 while studying the toxins produced in the venom of Conus victoriae, a marine cone snail found in tropical waters off the...

Study shows eutrophic lakes may not recover for a millennium
