Agreement will speed research on microbicides for women

...s unable to mount a strong antibody response. Each child of a person so affected has a 50 percent chance of inheriting the mutation and being predisposed to IgA deficiency and CVID. “A test for TACI defects would enable the diagnosis of more children and their relatives with these immune deficiencies,?say...

Defective Gene Linked to Two Inherited Immune Deficiencies

Studies clarify risk factors for mother-to-child transmission of hepatitis C virus

... transmission of the virus from infected mother to child was 6.2 percent in the European study and 3.6 percent in the U.S. study. "Our results strongly suggest that women should not be offered an elective caesarean section or discouraged from breastfeeding on the basis of hepatitis C infection alone," sa...

Researchers develop new testing methods for potential monkeypox or smallpox outbreak

.... In one case that has been previously reported, a child remained in a coma for 12 days. Due to similarities between the monkeypox and smallpox viruses, the smallpox vaccine likely kept these inoculated people from becoming seriously ill. The researchers believe these people were fully protected against m...

Mosquitoes are more attracted to individuals infected with malaria

...towards the mosquitoes. Researchers measured which child most attracted the hungry bugs. Koella et al. found that individuals attracted significantly more mosquitoes if they had the infectious stage of the malaria parasite. Moreover, when the children were treated with antimalarial drugs, there was no diff...

New technique helps identify multiple DNA regulatory sites

...iction of the chances that a couple will produce a child with a genetic disease. Frequent, widespread use of these devices is hindered by the fact that producing them is a painstaking process that involves at least 400 printing steps and costs approximately $500 per microarray.

Old drug, new tricks: Prospects for slashing the impact of malaria

... just one Fansidar tablet to an apparently healthy child during their routine infant immunization visits dramatically reduced the impact of any subsequent malaria infection. Used in this way, Fansidar does not prevent malaria but seems to produce a massive 50% reduction in death, debilitation and complicat...

Scientists focus on 'dwarf eye'

...a slight degree of farsightedness at birth. As the child grows and gains more visual experience, the eye adjusts its focus by growing, which changes the distance between the lens and the retina, the light-detecting layer of cells at the back of the eye. Once the retina is the right distance from the lens f...

New insights into how Huntington's disease attacks the brain

...he HD gene mutation will develop the disease. Each child of a parent with Huntington's disease possesses a 50 percent risk of inheriting the illness. In the United States, the disease strikes 30,000 people and places another 150,000 persons at risk. The disorder affects males and females equally and crosse...

Malaria killing a million a year

... said in New York. "It is a disease that kills one child in sub-Saharan Africa every 30 seconds. The numbers are astounding -- and unacceptable." Insecticide-treated bed nets and new artemisinin-based combination therapies must reach many more people, but "many countries are moving forward with malaria co...

Study Finds Moderate Hypothermia A Safe Treatment For Traumatic Brain Injury In Kids

...on, or unknown time when the injury occurred (i.e. child abuse) or were an adolescent (13-18 years old). Assessments of safety included mortality, infection, coagulopathy (blood clotting), arrhythmias and hemorrhage as well as ability to maintain target temperature, mean intracranial pressure (ICP), and p...

Ancient DNA helps clarify the origins of two extinct New World horse species

...s in the Late Pleistocene - as horses are a poster child of evolution," says Cooper. To explore the origins of the horses, the authors examined mitochondrial DNA (mtDNA) extracted from fossilized horse bones. Mitochondria, which have their own genome, contain a stretch of sequence that's useful for inferr...

Asymptomatic HIV babies could use earlier treatment
