A study by Sandia National Laboratories found that traditional sampling methods for detecting anthrax spores are ineffective, leaving up to 80% of spores behind. The researchers used coupons seeded with Bacillus atrophaeus spores and found that no method was very efficient, with the vacuum method collecting only 20% of the spores.
Researchers propose strength-training as an alternative to current lymphedema treatment guidelines. Studies have shown that women with breast cancer can benefit from upper-body strength training without increasing the risk of lymphedema.
A retrospective analysis of patients with invasive aspergillosis showed that those who initially received Pfizer's antifungal agent VFEND had better survival rates and were less likely to need salvage therapy than those on amphotericin B. The study found that patients who started on VFEND also had higher success rates in switching to o...
The Center for Child Injury Prevention Studies (CChIPS) aims to translate research findings into tangible innovations in safety technology and public education programs. CChIPS researchers are working on various projects, including studies on young driver performance, booster seats, LATCH systems, and forward-facing child seats.
Researchers found that middle-age adults are more likely to use complementary and alternative medicine (CAM) for prevention rather than treatment, with biologically-based therapies used equally for both purposes. The study analyzed data from the 2002 National Health Interview Survey, covering 31,044 participants.
Scientists have developed a laser imaging technique that can assess bone strength more accurately, predicting the likelihood of young women developing osteoporosis in later life. By measuring collagen content, the new Raman spectroscopic technique eliminates the impact of overlying tissues.
The study found a 28% decline in invasive pneumococcal disease among adults aged 50 years and older, with significant reductions in cases caused by PCV-7 serotypes. The researchers estimate that 12,500 fewer cases and 1,100 fewer deaths occurred among older Americans between 2002 and 2003.
Researchers outline new approaches to help developing countries address neglected diseases by pooling resources through health innovation networks. The recommended approach emphasizes harmonized development in six sectors, including manufacturing, research and development, and intellectual property systems.
A comprehensive US clinical trial reveals that competing medicated stents are equally effective in preventing target vessel re-vascularization (TVR) and major adverse cardiac events (MACE). The STENT registry, a nationwide study involving over 14,000 patients, provides insights into the efficacy of drug-eluting stents.
Researchers at Purdue University have developed a new type of medical imaging technique that uses gold nanorods to detect tiny structures in the bloodstream. The nanorods yield images nearly 60 times brighter than conventional fluorescent dyes, making them ideal for early detection of cancer.
Researchers have identified plant genes crucial for capillary root formation, a vital process for plants to absorb water and minerals. This discovery has important implications for sustainable agriculture, enabling the cultivation of crops that can adapt to changing environmental conditions.
A recent study has uncovered a natural quality control mechanism in cells that identifies and eliminates faulty messenger RNAs (mRNAs) containing premature stop codons, known as nonsense mutations. The mRNA-binding protein CBP80 plays a critical role in this process, allowing for the development of drug-based gene therapies to combat d...
A randomized controlled trial found that 80% supplemental oxygen reduced the risk of surgical site infections by nearly 54%. Patients with infections had significantly longer hospital stays and delays to ambulation. The study suggests that higher oxygen tensions may be a simple and effective way to reduce wound infections.
The NIH has awarded nearly $30 million to support research facility improvements, including new labs and animal housing at several institutions. The funding will enable enhanced research capabilities for studies on major illnesses like AIDS, cancer, and Alzheimer's disease.
A recent study reveals that human growth hormone (HGH) is illegal for off-label anti-aging use and can accelerate aging. The researchers warn that many people are unknowingly receiving the drug, which has high rates of serious adverse effects and may increase cancer risk.
The research discovered the structure of JAK2 kinase, a well-validated drug target for cancer and other disorders. The discovery will enable the development of specific molecules to treat diseases where JAK kinases play a pivotal role, leading to a rapid growth of phase I therapeutics.
A study found that telomerase activity in urine has high sensitivity and specificity for detecting bladder cancer, particularly in high-risk subgroups. The test is noninvasive, inexpensive, and easy to perform, making it a promising diagnostic tool for early cancer detection.
A new report by Express Scripts, Inc. found that U.S. consumers could have saved $20 billion in 2004 by using more generic drugs, with the most dramatic savings potential existing for generic gastrointestinals and anti-cholesterol medications.
Researchers developed a gene therapy using adeno-associated virus (AAV-8) to deliver a normal copy of the delta-sarcoglycan gene to skeletal and cardiac muscle cells. The treatment showed remarkable improvements in muscle function, structure, and endurance in hamsters with muscular dystrophy.
A new study reveals that targeting the brain chemical methionine enkephalin (Met-Enk) with antisense molecules can alter brain function and increase alcohol consumption in mice. This breakthrough could lead to a new class of drugs for treating Alzheimer's disease and possibly even alcoholism.
Researchers precisely imaged and counted color-receptive cones in a living human eye for the first time, revealing that color perception goes beyond hardware limitations. The brain's normalization mechanism balances colors despite variations in the visual system.
A study by Rice University economists found that high private sector lawyer salaries in certain regions affect the likelihood of federal prosecutors taking drug cases to trial. This occurs because government positions are less competitive, leading experienced lawyers to seek trials to gain valuable courtroom experience.
A study published in The Journal of Sexual Medicine found that treatment of men with erectile dysfunction (ED) significantly improved women's sexual function scores in all domains. The researchers discovered a link between the physiological changes of one partner affecting the other, highlighting the importance of addressing ED to impr...
The new classification recognizes six major clusters of organisms, including Opisthokonta, Amoebozoa, Excavata, Rhizaria, Archaeplastida, and Chromalveolata. These clusters have significant implications for our understanding of eukaryotic diversity and its impact on various fields such as medicine and agriculture.
Researchers found that a home-based environmental intervention significantly reduced asthma symptoms and associated healthcare use in inner-city children. The cost per symptom-free day was $25.57, offsetting the intervention's expenses.
Research finds that heavy rainfall and flooding can lead to more dust being released into the atmosphere, especially in regions like the Tigris-Euphrates Basin and North Africa. In contrast, areas with more vegetation and lower wind speeds tend to experience a decrease in dust emissions.
Researchers at NC State have successfully transferred genes from a heat-tolerant sea microbe, Pyrococcus furiosus, into tobacco and Arabidopsis plants to enhance their resistance to extreme temperatures. The study's findings show promise for developing plants that can thrive in harsh conditions on Mars and other planets.
