A new study found that cardiac surgery patients with serum potassium levels below 3.5 mmol/L are twice as likely to experience arrhythmias and a doubled need for cardiopulmonary resuscitation. Investigators recommend screening and replenishing potassium on a case-by-case basis.
Researchers at Purdue University discovered a new oxygen-sensing material that could improve car exhaust systems and medical devices. The material, ferroelectric thin film, shows promise for environmental and biological applications but has a drawback: its sensitivity to oxygen affects performance in computer memory.
Researchers found that HIV-infected pregnant women receiving care at specialized centers or state-funded sites were more likely to receive antiretroviral therapy, reducing transmission by up to two-thirds. The study highlights the importance of access to quality medical care in preventing mother-to-newborn transmission of AIDS.
Dutch chemists have developed a liquid containing metal nano-rods that can be regulated electrically to screen out sunlight. The rods' orientation is controlled by an electrical field, affecting light absorption and transmission. This innovative technology holds potential for applications in sunscreens and other devices.
New research suggests that PSA testing alone cannot fully explain the decline in prostate cancer deaths since the early 1990s. Instead, other factors such as changing treatment patterns and misclassification of cause of death may be contributing to the trend.
Researchers from the University of Iowa have identified a feedback loop mechanism that could explain the prolonged nature of migraines. The discovery reveals that inflammatory agents released during a migraine stimulate certain neurons to increase calcitonin gene-related peptides (CGRP) secretion, leading to persistent pain.
Physicists at the University of Amsterdam have developed a new method for treating port wine birthmarks using a red laser light. The improved wavelength allows deeper blood vessels to be accessed without damaging surrounding skin tissue, leading to more effective treatment outcomes.
The QuikScat satellite, launched on June 19, will provide daily snapshots of ocean winds to improve weather forecasting. The satellite is controlled by students and faculty at CU's Laboratory for Atmospheric and Space Physics.
A study conducted at nine U.S. Centers found that a testosterone skin patch improves sexual function and psychological well-being in surgically menopausal women. The patch was well-tolerated and showed significant benefits in improving the quality of life for these women.
A new study shows that International Maritime Organisation (IMO) rules are being applied globally, even by countries not bound to them. This shift indicates the IMO has taken on a universal law-making role, overseeing safety at sea and pollution prevention.
Researchers at WashU Medicine found that high doses of cortisol, produced in response to stress, can significantly impair memory performance after several days. Memory impairment was seen only in those who received a high dose of cortisol and only after four days of treatment.
Researchers found that women with a history of depression had smaller hippocampal volumes than those who never had been depressed. This is significant because the hippocampus plays a crucial role in learning and memory. Treatment not only prevents suffering but may also limit long-term damage to the brain.
A unique NIH study will use advanced MRI technology to diagnose heart attacks and strokes more quickly and accurately, potentially saving lives. The study aims to learn whether MRI can identify heart attacks and strokes earlier, allowing for timely treatment.
A new study by UCSF researchers found a significant decline in TB rates in San Francisco from 1992 to 1997, attributing it to intensified control measures. The study used molecular epidemiology to track the disease and determine the effect of interventions on transmission rates.
