Triple-drug therapy promising against African HIV subtype

A recent study found that patients with previously untreated HIV-1 infection, especially those co-infected with pulmonary TB or KS, showed rapid responses to triple-drug therapy. After three months, nearly all patients achieved undetectable HIV RNA levels and experienced significant increases in CD4 cell counts.

Highlights of January Journal of the American Dietetic Association

Research reveals that nearly 90% of adults and children consume caffeine from coffee, soft drinks, and tea, while 62% of parents with chronically ill children use dietary supplements without their healthcare provider's knowledge. This raises concerns about potential adverse drug-herb interactions.

Cervical cancer treatment depends on patient age

A study of over 1,500 cervical cancer patients found that older women received less surgery and radiation therapy than younger counterparts. Treatment choices were influenced by tumor stage, medical conditions, and advanced age, which independently affected survival rates.

UT Southwestern researchers find calcium intake contributing factor in formation of kidney stones

Researchers found that urinary calcium levels play a significant role in the formation of both calcium oxalate and calcium phosphate stones. The studies suggest that patients with elevated intestinal calcium absorption and urinary calcium levels may need to limit their calcium intake to prevent kidney stone formation.

OHSU researcher says FDA could broaden access to results of clinical drug trials

OHSU researcher recommends increasing public access to FDA's clinical trials registry and results database. This would provide a comprehensive view of drug efficacy and safety, benefiting healthcare providers, researchers, and the public. The FDA could make its reviews more user-friendly with minimal staffing increases.

UCLA-VA study names India dietary staple as potential Alzheimer's weapon

A UCLA-VA study found that curcumin inhibits beta amyloid formation and breaks up existing brain plaques in genetically altered mice. Curcumin's low molecular weight and polar structure allow it to penetrate the blood-brain barrier effectively, making it a promising treatment option for Alzheimer's disease.

Evidence that human brain evolution was a special event

A study found that genes controlling brain development and function evolved significantly faster in the human lineage than in other species. This suggests that strong selective forces favored larger and more complex brains, leading to a dramatic speeding up of evolution.

Geologist comments on Oregon's tsunami hazard

Scientists studying uplift along the Oregon coast reveal similarities with past earthquakes, indicating an accumulation of strain for a potential future earthquake. A tsunami could cause widespread damage from Northern California to Vancouver, B.C., with waves arriving within minutes after shaking ends.

Ants' 'genetic engineering' leads to species interdependency

In two harvester ant populations, queens and workers from the same colonies are genetically very different, with only queens coming from pure species-specific lineages. The ants have committed to a hybrid workforce strategy, relying on interspecific hybrid workers for survival.

Bound for destruction

Researchers at RIKEN Center for Developmental Biology identified Nedd4 as a key player in protecting the Notch receptor from activation. The study found that Nedd4 works as an antagonist of Notch signaling, suppressing its activity and preventing molecular loose cannons from fouling the precisely ordered workplan.
