A large-scale study confirms that the cardiac surgery drug aprotinin increases death rates and damages kidney function. The study analyzed data from over 10,000 patients and found that those who received aprotinin had higher mortality rates and impaired kidney function compared to those who did not.
A University of Houston professor found a new side effect of lead exposure: obesity in male mice born to mothers exposed to varying levels of lead. The study suggests that the link may be related to testosterone or other hormones, and highlights the need for lower acceptable lead exposure rates for pregnant women and children.
New research finds that hemoglobin A1c test underestimates true glucose control in hemodialysis patients, potentially leading to inadequate treatment and poor outcomes. The study suggests the use of a newer test, glycated albumin, as a more accurate measure of blood sugar control for diabetic dialysis patients.
A Cornell-led study comparing 15 African-Americans and 20 European-Americans found proportionately more harmful genetic variations in Europeans. Computer simulations suggest that the first Europeans had smaller and less diverse populations, allowing mildly harmful variations to become more frequent over time.
Researchers at Massachusetts General Hospital have identified a new strategy for normalizing tumor blood supply by controlling nitric oxide levels. By selectively suppressing NO production in tumor cells while maintaining it in blood vessels, the study found improved appearance and function of the tumor's blood supply.
A University of Alberta study found that beaver presence increases open water availability by up to nine times, providing habitat and resources for land animals, amphibians, and livestock. The study suggests climate models predict increased drought frequency and length, where beavers can play a crucial role in maintaining wetlands.
A new study published in Human Communication Research found that exposure to racial bias in television programming can have a negative impact on viewers' perceptions. The study showed that unfavorable portrayals of Latinos led to decreased evaluations of their education and qualifications, promoting an us-versus-them mentality.
A recent study published in Archives of General Psychiatry found that genetic and environmental factors play a crucial role in shaping cortisol responses to stress in young children, with family context being a significant determining factor.
The study characterizes over 500,000 DNA markers in the human genome and examines variations across 29 populations on five continents. It reveals a wealth of information about human migration patterns, genetic diversity, and disease-related genes.
Psychologists Agneta Herlitz and Jenny Rehnman found significant sex differences in episodic memory, favoring women. Women excel in verbal episodic memory tasks and are better at remembering faces, especially of females.
A new study suggests that drinking fat-free milk may offer protection against hypertension in women. Women who consumed more low-fat milk and had diets higher in calcium and vitamin D from foods tended to have a lower risk for developing high blood pressure.
A NASA study reveals that warming air temperatures are causing the surface of Greenland's massive ice sheet to melt, leading to loss of ice throughout the mass beneath. The team found a strong connection between melting on the surface and ice loss below 6,500 feet in elevation.
Middle-aged women's waistlines have widened in recent years, increasing their stroke risk. The study found that obesity and blood sugar markers are key contributors to this trend, highlighting the need for obesity-curbing efforts.
The Häagen-Dazs brand has gifted a new garden design to Penn State's Harry H. Laidlaw Jr. Honey Bee Research Facility, featuring interconnected gardens and educational spaces. The design aims to provide year-round food sources for honey bees and raise public awareness about their plight.
Scientists at Dana-Farber Cancer Institute have found an alternate pathway to angiogenesis, triggered by PGC-1alpha sensing low oxygen levels. This discovery may offer new opportunities for treating heart and blood vessel diseases.
Researchers at Sainte-Justine Hospital and Université de Montréal have identified the CD36 receptor as the key cause of dry AMD. This discovery brings hope for new therapies to treat the blinding eye disease, which affects 30 million people over 50 worldwide.
Researchers from Boston University School of Medicine found that previtamin D3 production varies depending on skin type and weather conditions. Vitamin D deficiency is common worldwide, with increased risk of cancers and autoimmune diseases associated with higher altitudes.
Studies found that stroke patients who arrive in the emergency department during off-hours, especially on weekends, are more likely to die in the hospital. Hemorrhagic strokes showed a significant increased risk of mortality compared to ischemic strokes.
A new study found that cognitive impairment is decreasing among people aged 70 and older, with better education and financial status being significant contributors. The decline in cognitive impairment may be attributed to improved cardiovascular health, as risk factors like high blood pressure and smoking were more prevalent in the 1990s.
Scientists have discovered a gene expression pathway that exerts a sweeping influence over the process of oxidative stress. This pathway could potentially be manipulated to mitigate damage caused by oxygen and prevent diseases such as heart disease, stroke, and aging.
Researchers have developed a nanotech approach using coated silica particles that can efficiently remove biological molecules, pathogens, and organic pollutants from water. This innovative method could help prevent disease and poisoning for millions of people worldwide.
