A Medical College of Georgia study found that individuals with higher lean body mass can better regulate their blood pressure in response to stress. This is because fitness allows the body to efficiently excrete sodium, which helps lower blood pressure back to normal.
Researchers argue that female condoms are a vital method of protection against HIV/AIDS but have been dismissed due to cost and esthetics. Advocates need to reposition the product as an empowering way to approach reproductive health, emphasizing its benefits in reducing transmission of AIDS.
Researchers found a significant decline in Guillain-Barré syndrome (GBS) reports following influenza vaccination, with annual rates decreasing by 4-fold between 1993-1994 and 2002-2003. A GBS diagnosis was confirmed in 82% of reports, and preceding illness within 4 weeks of vaccination was identified in 24% of cases.
The study found that older adults who received mental health treatment benefited considerably, refuting the notion that interventions are less effective for this age group. Mental health problems in later life lead to significant social, economic, and medical costs.
Researchers at Purdue University have developed a method to align carbon nanotubes and filaments, similar to collagen fibers in real bones. This alignment improves cell adhesion and growth, potentially leading to better artificial joints that last longer and attach more securely to human bones.
A new microgenerator has been successfully developed by Georgia Tech researchers, capable of producing useful amounts of electricity and powering small electronic devices. The device's high-speed spinning magnet produces 1.1 watts of power, a significant advancement in microengines that could replace conventional batteries.
The National Center for Regenerative Medicine will enable groundbreaking research discoveries using non-embryonic stem cells to treat thousands of patients annually. The center's education programs will train personnel in performing innovative research and delivering world-class patient care.
Researchers found that individual fibroblasts in rat and mouse tissues exhibit robust, persistent circadian rhythms of clock gene expression for at least 1-2 weeks in culture. This discovery confirms that peripheral tissue clocks are indeed independent and self-sustaining.
Researchers found that low-glycemic-load diets resulted in smaller decreases in resting energy expenditure and less hunger compared to standard low-fat diets. The study also showed significant improvements in insulin resistance and risk factors for cardiovascular disease.
A study of 401 US pharmacists found that they are concerned about the safety and quality of imported prescription medications. Pharmacists generally favored regulatory actions to decrease counterfeiting and believed that US pharmacy oversight could mitigate safety risks if importation is allowed.
Researchers discovered two proteins that chaperone odorant receptors to the surface of olfactory nerves in mice, enabling them to match nearly 1,000 different mouse odorant receptors with specific chemicals. This breakthrough opens up new possibilities for understanding the mechanisms underlying our sense of smell.
A recent study found that obesity is a modifiable risk factor for atrial fibrillation, with obese individuals having a significantly higher risk of developing the condition. The study examined data from the Framingham Heart Study and found that age-adjusted incidence rates for AF increased across BMI categories in men and women.
A low-glycemic load diet was found to be more effective in reducing hunger and improving metabolic rate during weight loss. The diet also showed beneficial effects on several obesity-related risk factors compared to a low-fat diet.
Researchers from UGA found that Georgia's recent drought, combined with an opportunistic parasite, led to the decline in blue crab numbers. The study reveals that the delicate balance of saltwater and freshwater in coastal estuaries is disrupted during droughts, creating a favorable environment for the parasite to thrive.
Researchers have discovered the structure of human POT1, a protein that caps the ends of chromosomes and regulates telomere length. The protein binds to a ten-nucleotide sequence, protecting the telomere from erosion, and its structure suggests that telomerase activity is regulated by this complex.
Researchers explore links between chronic stress in birds, depleted medieval fish stocks, and the costs of extended lifespan. Studies reveal how food and predators impact physiology and demography in songbirds and propose a norm for inseparable effects on both.
Adults with diabetes have experienced a 50% reduction in the rate of incident CVD, while those without diabetes saw a 35% reduction. Patients with diabetes have benefited from similar declines as those without, with substantial room for further progress to reduce high CVD event risks.
Professor Daphne Maurer's research found that infants perceive sounds as colors and associate certain feelings with tastes. As individuals develop, these connections are often inhibited, leading people with synesthesia to experience the world differently.
Kohn's bioresorbable polymer was successfully licensed and incorporated into REVA Medical's stent devices. The collaboration resulted in rapid development and early pre-clinical study success.
The University of Manchester has developed a new technique that allows scientists to study protein molecules in complete detail, doubling the number of visible atoms compared to current methods. This breakthrough enables the creation of more effective medicines by targeting specific proteins.
Recent studies suggest that two chemical signals, Hedgehog and Wnt, play a key role in the development of certain cancers. These signals are also active in normal stem cells that repair damaged tissue, raising the possibility that some cancers may start from these cells with accumulated mutations.
The study reveals that light-to-moderate grazing has no ill effects on the ecosystem, and can even increase vegetative ground cover and plant diversity. In contrast, ungrazed lands show more cheatgrass and reduced plant variety, highlighting the benefits of managed livestock grazing.
Scientists on a research cruise off the Alaskan coast have identified previously undiscovered deep-sea habitats and sparked debate about the causes of a devastating 1946 tsunami. The expedition used cutting-edge technology to map the seafloor, collect sediment samples, and probe the region with an ROV.
Researchers successfully produce spider silk fibers in insect cell cultures using genetic engineering, opening the way for commercial development. The fibers possess chemical resistance characteristics similar to those produced by spiders.
