Researchers found that estrogen replacement therapy accelerated wound healing in elderly postmenopausal women, outperforming those not on hormone therapy. The study suggests that hormone replacement therapy may benefit chronic wounds in older patients.
Historic farm plots show that over-fertilizing can actually decrease crop yields and make production unstable. Long rotations and sustainable farming practices are more effective in increasing organic matter and nutrients to the soil.
A consensus group of breast cancer specialists has developed a classification system for DCIS, taking into account nuclear grade, necrosis, polarization, and architecture. The new system aims to improve patient treatment and discrimination between less aggressive and more aggressive cases.
A recent study found that women who perform specific components of Breast Self Examination (BSE) may have a reduced risk of dying from breast cancer. The three key components associated with this benefit are visually examining the breast, using finger pads to examine the breast, and using three middle fingers to examine the breast.
Researchers at Penn State have developed a new process for producing ultrafine metal powders, including silver and nickel, using a laser, household blender, and inexpensive reaction materials. The process produces particles in the 1-100 nanometer range, smaller than bacteria or viruses, with improved purity and uniformity.
A University of Illinois geneticist criticizes the misuse of genetics in society, citing the controversial book 'The Bell Curve' as an example. Jerry Hirsch argues that the field has been misunderstood and mishandled, leading to flawed conclusions about intelligence and racism.
Researchers at Columbia University Irving Medical Center identified the P-TEN gene as a new breast cancer susceptibility gene. The discovery could lead to better tests for early detection and more effective treatments for women with Cowden's syndrome, an autosomal dominant disorder that increases breast cancer risk by 50-75%.
The University at Buffalo's National Center for Earthquake Engineering Research has been awarded a $10 million grant by the NSF to study advanced technologies for minimizing earthquake damage. The center aims to quantify the earthquake threat, develop new technologies, and improve emergency response through the use of advanced technolo...
Researchers found that small-intestine digestibility and nutritive value are essentially equal in pet foods containing raw meat or animal by-products. Pet owners can opt for premium diets rich in protein with fewer stools and less gas, but at a higher cost.
A new book by Bonham Richardson examines the economies, environments, and societies of Caribbean islands St. Lucia, St. Vincent, Grenada, and Barbados. The study reveals how working people influenced British decision makers to develop unique adaptations to economic and geophysical stresses.
Researchers found that tightly controlling blood sugar levels can significantly decrease the lifetime risk of diabetes-related blindness for people with early-onset type 2 diabetes. For those who develop the disease at an age of 50-55 or earlier, maintaining a near-normal blood-sugar level can prevent vision and kidney problems.
Experiments show that young children under 3 have difficulty recognizing non-obvious symbols, such as a smaller doll in a miniature room. However, when they think the spaces are the same thing, they can apply their knowledge. Researchers used a 'shrinking machine' and live video presentations to study this phenomenon.
Researchers found that using Interferon-alpha, a cancer treatment agent, can extend the preservation time of donor livers and improve their function. This novel approach may significantly help future liver transplant patients by allowing for more time to prepare the organ.
Researchers attribute the increase in SIDS deaths to colder months and overbundling, while experts recommend placing babies on their backs to sleep, using firm mattresses and removing soft materials. Early prenatal care, breastfeeding, and smoke-free zones also reduce SIDS risk.
A 12-year study found that attending religious services was associated with healthier behaviors, stronger social ties, and improved emotional well-being in elderly individuals. The study revealed that religious attendance acted as a linchpin for overall health practices, friendships, and leisure activities.
Chemical engineers at the University of Illinois are developing carbon-based sorbents to remove hydrogen sulfide from coal-gas streams, increasing efficiency and reducing greenhouse gas emissions. The new materials can effectively capture hydrogen sulfide and convert it into valuable byproducts.
A portable, hand-held biosensor has been developed to detect a wide range of medically important chemical compounds. The device, capable of detecting tiny concentrations of specific molecules, may represent a new type of practical and affordable device for various medical applications.
