A first-of-its-kind oral drug, bosentan, has been shown to reverse the deadly consequences of primary pulmonary hypertension (PPH) and improve patients' quality of life. By increasing exercise capacity and improving heart function, bosentan reduces symptoms such as shortness of breath and fatigue.
Recent research shows that jurors' comprehension of scientific evidence is a significant challenge, particularly when dealing with complex and nuanced facts. Dr. Solan identifies several problems, including diminished juror comprehension, inappropriate influence by expert credentials, and varying understandings of causation concepts.
University of Toronto researchers suggest a five-point strategy to address equity issues in health genomics. The plan includes research on ethical and social issues, training policy makers, and creating an investment fund to improve health in poorer countries.
Dr. Anthony S. Fauci has been recognized for his significant contributions to understanding the regulation of the human immune response and the pathogenesis of HIV disease. He has developed effective therapies for formerly fatal diseases and has pioneered strategies for therapy and immune reconstitution of patients with AIDS.
A large study has found that retinal blood-vessel damage is associated with an increased risk of stroke. Damage to the small blood vessels in the retina was linked to a doubling of stroke risk, regardless of age, sex, or other health factors.
The study found that critically short telomeres signal cells to arrest or die, rather than average length. Turning on telomerase can restore function without significantly increasing overall telomere length, offering new insights into cancer treatment options.
Biologists discovered that chromosomes fuse together due to telomere replication and distinct protein functions. The study found two types of telomeres and the roles of proteins in normal cell function.
A study by Julie Etterson found that native prairie plants like the partridge pea may not adapt quickly enough to changing climate conditions. The plants' evolutionary responses to drought and heat are unlikely to keep pace with the predicted rate of climate change, threatening their survival.
Biochemistry assistant professor Mark Glover has recreated the three-dimensional structure of a critical portion of the BRCA1 protein, a breakthrough that could lead to early detection and genetic screening for breast cancer. The findings may also provide new insights into how the protein prevents cells from becoming cancerous.
Approximately 59% of men and 52% of women in Britain are in 'non-standard' jobs, often with reduced union coverage. Despite trade unions' efforts to recruit more workers in non-standard positions, there has been no significant expansion of union membership among these employees.
Researchers found that certain fish muscles specialized for fast mating calls are now mutually exclusive with other functions like swimming. The study, on toadfish Opsanus tau, reveals the limitations of biological systems when optimized for one function.
A study found that US direct-to-consumer ads often use emotional appeals and vague descriptions of medication benefits, rather than providing quantitative data. This lack of transparency may lead to unrealistic expectations and increased demand for costly prescription drugs.
A new study by the Institute for Operations Research and Management Sciences found that consumers are more likely to maintain their vehicles properly if they have high-quality auto ratings. The study reveals three key lessons for manufacturers, dealers, and distributors: pricing power, customer loyalty, and leasing operations.
Researchers from SurroMed and Penn State University have developed Nanobarcodes particles, which can identify individual particles using optical microscopy. This technology enables multiplexed bioassays in solution, revolutionizing life science research and disease diagnosis.
A unique gene has been identified as a regulator of stem cell growth, suggesting that embryonic and adult stem cells share key genes and properties. This discovery could lead to the development of new therapies for cancer patients in need of stem cell transplants.
A study published in The Lancet found that prescription-drug advertisements rarely quantify a medication's expected benefit and instead rely on emotional appeals. This lack of clear information can lead to consumer misinformedness about treatment options and potential side effects.
Research by Professor Alison Booth finds that women are held back by a combination of factors, including lower pay increases after promotions and differences in internal job offers. Temporary work can be an advantage for women, but men who start with temporary jobs never achieve the same salaries as men in permanent jobs.
The collaboration between Myriad Genetics and the University of Utah revealed that the Tsg101 protein is essential for HIV1 budding, allowing for the disruption of the virus lifecycle. This breakthrough led to the identification of potential HIV drug targets, with lead compounds developed for anti-HIV therapy.
Researchers at Penn State University and SurroMed, Inc. have developed a novel method for encoding information on the submicron scale using microscopic metallic barcodes. These patterned metallic particles can simultaneously monitor multiple biological reactions in very small volumes of fluid.
