Researchers at Wyeth determined the three-dimensional structure of PKCΘ, a key signaling molecule in T lymphocytes. This discovery has potential to identify selective inhibitors for autoimmune diseases by disabling T cell activation.
The Texas Bison Herd is struggling due to inbreeding depression, a condition caused by lack of genetic variation. The herd's average age has increased, and birth rates are low, posing a threat to its survival.
Researchers detected distinct brain activation patterns in individuals carrying the APOE-å4 risk factor and found potential evidence of early Alzheimer's changes. The study suggests that these individuals may be compensating for damage by switching to alternate brain networks, providing insights into disease predisposition.
A recent study found that medication errors are often caused by late administration, workplace distractions, and inadequate staffing. The researchers also highlight the benefits of using bar code medication administration systems and paperless charting systems to reduce errors.
Researchers discovered a new mechanism by which Helicobacter pylori bacteria can stick to stomach cells, allowing them to survive a strong immune response. By recombining DNA from two related genes, the bacteria can create a functional BabA gene, enabling it to bind tightly to Lewis B receptors.
A massive infestation of invasive sea squirt Didemnum has been found on Georges Bank, covering 50% or more of the seabed. The species is threatening commercial fish species and altering seabed communities.
Studies found that sit-down rounds significantly improved patient outcomes, including healthy levels of albumin and hemoglobin, lower hospitalization rates, and reduced mortality. Patients treated at clinics with regular sit-down rounds had better care team communication and were more likely to be white, married, or high school graduates.
Intellectual property experts argue that the NIH proposed policy does not alter existing copyright law, but rather builds on current practice to facilitate public access to research. This change is seen as advancing the NIH's aim to use today's information technologies to fulfill its public mission.
Researchers found that fasting reduces phospholipid levels in the heart by up to 40% after 12 hours, allowing mitochondria to become more energy-efficient. After feeding resumes, phospholipid levels return to normal, but triglyceride levels remain elevated, hinting at a memory of deprivation.
Researchers at UCSB discovered a key mechanism by which E. coli bacteria adhere to the urinary tract. The finding sheds light on the mechanisms driving urinary tract infections, allowing for potential new treatments and survival strategies under stressful conditions.
The NIH has awarded a grant of $540,000 to train 1,200 middle school teachers in the use of MedMyst, a web-based science curriculum that uses interactive computer adventures to teach kids about infectious diseases and microbes. The training will allow teachers to enrich the science curriculum for 150,000 students over two years.
A Swedish study has found a statistically significant correlation between the degree of Chernobyl fallout and an observed rise in cancer cases. The study monitored over 1,143,000 individuals for cancer development after being exposed to low levels of radioactive cesium-137.
Researchers found that alcohol impairs brain areas controlling motor functions, leading to increased speeding and crashing. Brain regions involved in decision-making and working memory were not affected until drivers reached a blood alcohol level of 0.08.
Researchers discovered that overexpression of Down Syndrome Critical Region 1 (DSCR-1) reduces tumor growth and blocks blood vessel formation. This breakthrough could lead to novel strategies for inhibiting endothelial cell dysfunction and abnormal blood vessel formation.
A new study found that taking vitamin E daily can reduce the risk of heart attack by 43% and dying of heart disease by 55% in diabetic patients with haptoglobin 2-2. The results suggest a significant public health benefit for this group, who are at high risk of cardiovascular disease due to their genetic profile.
