The study found increased condom use in intervention groups but no impact on HIV incidence, highlighting the need for more effective STI and behavioral interventions to control HIV in Uganda. The researchers emphasize the importance of rigorous evaluation and development of promising interventions.
Researchers have developed a model that may mimic how cells assemble themselves to form large-scale supramolecular structures. The technique uses tree-like organic molecules to create spheres with complex lattices, potentially paving the way for photonics applications.
Researchers identified ghrelin as a hormone that stimulates feeding when introduced to specialized brain cells. Increased ghrelin levels in response to weight loss or reduced caloric intake lead to increased appetite and eating in both mice and humans.
The ACCORD clinical trial enrolls 10,000 adults with type 2 diabetes to test the effects of intensively controlling blood sugar along with aggressive control of blood pressure and lipids. The study aims to address the significant public health challenge of cardiovascular disease in people with type 2 diabetes.
A research team found a fly mutation that causes early cell death and neural degeneration in the brain, similar to human neurodegenerative diseases. The mutation is associated with protein aggregates found in human Alzheimer's patients.
Researchers at Johns Hopkins' Center for Cardiovascular Bioinformatics and Modeling are using IBM technology to simulate complex heart cell models and analyze thousands of genes. This knowledge could lead to new drug targets and better predictions about the effects of drugs on animals and humans.
Researchers found that quitting smoking has psychological benefits and encourages continued efforts at smoking cessation. However, unsuccessful quitters' declining perceptions of health risk must be changed to help them quit in the future.
A new study aims to investigate the effects of intensively controlling blood sugar, blood pressure, and lipid levels on cardiovascular disease risk in adults with type 2 diabetes. The ACCORD study will test three medical treatment strategies to determine their impact on CVD risk.
A researcher is studying how tumors pirate angiogenesis, the formation of new blood vessels, to survive. Dr. Motamed focuses on protein SPARC, which regulates growth factors and has multiple roles in cancer and new blood vessel formation.
Adolescents with two smoking parents are 3.8 times more likely to smoke than those with both non-smoking parents. Quitting smoking by parents can reduce the likelihood of their adolescent smoking, especially when both parents are non-smokers.
A newly discovered fossil from Tanzania provides a key anatomical link between two other known specimens, H. rudolfensis and the original H. habilis type specimen. The discovery reshuffles our understanding of early human ancestry, suggesting that all three specimens are likely members of the same species - Homo habilis.
According to a study by Fred Pampel, measures of gender equality do not explain the gap between men's and women's lung-cancer death rates. The gap is best explained historically, with women's smoking following men's on the upswing after a typical lag of around three decades.
A study published in The Lancet found that accident risk is doubled during the last half hour of a two-hour work period, suggesting that shorter breaks can help mitigate this risk. More frequent short breaks may improve work performance and reduce fatigue, making them a potential strategy to prevent industrial accidents.
Research analyzed DNA differences among 50 squirrel genera to deduce their interrelationships and evolutionary history. The study found that climate change and geological events played a significant role in shaping the squirrel family tree, with major branches diverging around 5 million years ago.
Researchers found that individuals with two copies of the met form of the COMT gene had a more pronounced response to pain, while those with two copies of the val form reported less pain and fewer negative emotions. The study used PET brain imaging and controlled jaw pain to investigate the role of genetic variation in pain tolerance.
Researchers use bio-ferrography to capture tiny particles in synovial fluid, enabling the creation of a diagnostic atlas for orthopedic surgeons. The atlas will help identify potential problems with implants prior to revision surgery.
A meta-analysis of 31 trials involving over 4400 patients found that continuous antidepressant treatment for one to two years significantly reduced depressive relapse rates compared to placebo. The study suggests that many patients remain at risk of recurrence after initial treatment and may benefit from extended medication
A Virginia Tech study found that women are increasingly finding their homes to be a haven of satisfaction, rather than their workplaces. This challenges the long-held assumption that women seek work as an escape from family obligations.
A study published in The Lancet found that treatment for one to two years with antidepressants substantially reduced the likelihood of relapse compared to discontinuing active treatment. The average rate of relapse on placebo was nearly double that of treatment, highlighting the benefits of long-term medication adherence.
Researchers found that both nortriptyline and bupropion, when combined with counseling, helped smokers attain periods of abstinence but had limited effectiveness in quitting for a year. The study showed that antidepressant therapy and counseling can aid in achieving short-term abstinence for cigarette smokers.
The Singleton case has raised concerns about forced medical treatment of the mentally ill and its impact on the death penalty. The US Supreme Court must rule against this practice to restore competence for execution as a medically and ethically untenable dilemma.
Researchers found that specific genetic variants, such as the val158met polymorphism in the COMT gene, influence an individual's sensitivity to pain. This genetic variation affects brain regions involved in pain perception and emotional regulation, leading to increased pain ratings and a more negative internal state.
A recent study by Imperial College London found that genetically modified mosquitoes (GM) lose their test marker gene rapidly when interbred with unmodified mosquitoes, posing challenges for malaria control. The researchers suggest using crossing regimes to minimize deleterious mutations and improve the competitiveness of GM mosquitoes.
A new treatment option for heroin addiction has shown a promising 75% success rate in reducing opiate use, according to a recent study. The combination of buprenorphine and intensive psychosocial therapy was found to be effective in preventing relapse and reducing criminal activity among patients.
Researchers at Rockefeller University reveal a crucial link between the Ezh2 protein and chromatin modifications, enabling the development of a wide range of antibodies. The discovery provides new insights into B cell biology and the immune system.
Two studies found that bidis and reduced-exposure products marketed as less toxic do not effectively reduce smokers' exposure to lethal constituents of cigarette smoke. Instead, they may promote heavier smoking and introduce new risks.
Researchers at Zengen developed a 'super peptide' that kills Candida albicans with high candidacidal activity, outperforming existing antimicrobial peptides. The discovery may help understand the unique mechanism of action of a-MSH peptides and unlock new treatments for fungal infections.
The Lancet reports a severe decline in Iraq's healthcare infrastructure, exacerbated by the Gulf War and 12 years of economic sanctions. The US military's preparation for chemical and biological warfare has also contributed to the humanitarian disaster.
Researchers found that selegiline hydrochloride significantly increased smoking cessation rates among participants, with 45% quitting after 8 weeks of treatment. This suggests the MAO-B inhibitor may be an effective treatment for nicotine addiction.
Despite years of decline, trade unions are finding new ways to gain support and influence, such as community links and international agreements. Research shows that partnerships with employers and local consultation can drive growth, but challenges remain in certain workplace environments.
