By rapidly scaling up well-run existing programs, the study suggests that more HIV infections may be averted.
Adult neural stem cells give rise to three major brain cell types, but are specified to produce specific subtypes of neurons. The discovery suggests that creating specific neuron types may require replacing combinations of different neuronal types for effective reestablishment of neural function.
A new study by UCSF researchers suggests that pre-kindergarten tuberculosis skin testing is not a cost-effective way to spend healthcare dollars. The test would only be beneficial if at least 7% of children tested positive, which is now less than 1%. Instead, finding and treating adults with TB would be a more effective approach.

The cost of treating arthritis in the US has more than doubled between 1998 and 2003 due to the increasing number of people with the disease and inflation-adjusted prescription costs. Total medical care expenditures for arthritis patients increased by $88 billion annually, with estimated incremental costs reaching $81 billion.
A new study found that adjustable-height chairs with ergonomically curved seats can significantly reduce neck and shoulder pain in garment workers. The custom-designed chair, tested in a four-month trial, provided more benefit than traditional flat-seat pan chairs, particularly for thin workers and those with high hand-arm workloads.
Researchers found that a specific class of PCB causes significant developmental abnormalities in rat pups whose mothers were exposed to the toxicant during pregnancy and early nursing. The study suggests that non-coplanar PCBs may be particularly hazardous due to their stability and prevalence in environmental samples.
A study of pharmaceutical sales visits found that almost half led to doctors intending to increase gabapentin prescriptions. Nearly 40% of visits discussed off-label uses not approved by the FDA.
A study by Ugandan researchers found that interruptions in antiretroviral medication supply due to financial or logistical issues led to the development of drug resistance in HIV-infected patients. Despite near-perfect adherence, treatment interruptions created opportunities for resistance to develop.
UCSF scientists have discovered that chitin triggers an allergic inflammatory response in the lungs of mice, leading to increased production of the anti-chitin enzyme. The researchers suggest that people with less-effective versions of this enzyme may be more prone to asthma due to their inability to control exposure to inhaled chitin.
