Kytril was found to be significantly more effective than dolasetron in controlling acute chemotherapy-induced nausea and vomiting. The study, led by Dr. Marianne Tan, showed that 69.2% of patients treated with Kytril experienced total control of nausea and vomiting, compared to 23.1% for dolasetron.
A recent study reveals that feeding tubes do not necessarily improve the quality of life for patients with severe dementia. The study analyzed data from over 385,000 nursing home residents and found that states with higher rates of
In southern Jordan, a team led by Thomas Levy from UCSD discovered the largest Early Bronze Age metal factory in the Middle East, dated to ca. 2700 BC. The site yielded hundreds of clay casting molds and thousands of stone hammers, anvils, and other artifacts.
Self-tanners contain dihydroxyacetone (DHA), which interacts with skin proteins to create a brown glow. Newer sunscreens offer greater protection against both UVA and UVB radiation, including those developed by Craig Bonda, who found that adding DEHN to avobenzone extends its effectiveness.
A long-term industry-funded rat study has found no statistically significant increases in any tumor type, including brain cancer, after exposure to radio frequency radiation at common cell phone signals. The study builds on earlier research and suggests the greatest hazard with cell-phones is driving a car while talking.
Researchers discovered a molecular switch that guides cell communication before a message reaches the nucleus, adding complexity to understanding cellular signals. This switch determines which signal - calcium or cAMP - will be used, leading to different responses in target proteins and potential therapies for serious disorders.
The US Department of Energy's Argonne National Laboratory has developed a small, portable neutron detector that can detect hidden nuclear weapons and materials. The device uses a wafer of gallium arsenide coated with boron or lithium to detect neutrons, producing a cascade of charged particles that is easy to detect.
Great Lakes rip currents can be deadly, but knowing how to identify them and escape is crucial. Longshore currents flow along the shoreline, while rip currents flow perpendicular to it; always swim perpendicular to the current. Cold water multiplies danger, so take necessary precautions when swimming in cold water.
Researchers at Ohio State University have synthesized hydrogen thioperoxide (HSOH), a sulfur-containing molecule considered a 'missing link' in its chemical family. The molecule's unique spectral pattern was recorded using a new laboratory instrument, FASSST, allowing scientists to study it for the first time.
Research by Wake Forest University professor suggests that hormone replacement therapy can help prevent heart vessel disease when started at the right time. Studies on postmenopausal monkeys and younger women have found a strong link between estrogen therapy and reduced fatty build-up in the heart's arteries.
A population-based study suggests that a diet high in foods containing vitamin E may help protect against Alzheimer's disease, with the most significant protective effect found among those with the lowest dietary vitamin E intake. The study also found no association between vitamin E supplements and reduced risk of AD.
Researchers at Purdue University have developed a new approach to protect software by placing hundreds of tiny 'guards' throughout the code, making it harder for hackers to use the program without permission. The system has shown promising test results and is being licensed to a startup company, Arxan Technologies Inc.
Nearly a third of surveyed glaucoma patients reported difficulties with taking multiple medications, citing missed dosing and inadequate waiting periods. Physicians advocate for more patient education and convenient treatments to improve compliance and vision outcomes.
Mayo Clinic researchers have developed a new imaging test for diagnosing breast cancer using the MR elastography technique, which provides data on tissue stiffness. This technology has shown promising results in detecting breast cancer with high accuracy and may reduce the need for biopsies.
Researchers found that women with breast cancer were more likely to have lived closer together at birth and at menarche than those without the disease. Early environmental exposure may influence breast-cancer risk, according to the study's findings.
Researchers at Ohio State University have found that certain ceramic materials, called cuprates, can switch between two types of superconductivity under specific circumstances. This discovery could settle a long-standing controversy among scientists and potentially lead to the development of buckyball-like superconductivity in ceramics.
Researchers at Texas A&M University are investigating the healing properties of Aloe vera, particularly its polysaccharide, which binds growth factors in wounds and speeds up the healing process. The study aims to improve wound healing for elderly patients with bedsores, diabetic ulcers, and vascular ulcers.
Researchers studying isoprene emissions from oak trees in Houston have found that these reactions can lead to increased ozone production and ground-level air pollution. The study aims to understand the critical steps in this process to mitigate environmental damage.
Working parents spend the same amount of time physically present in school as non-parents, but find ways to care for their children by reducing personal time and leisure activities. Teachers with older children also contribute to childcare by taking on extra duties.
The study aims to optimize planned control of the parasitic fish that have had a devastating impact on native fish populations in Lake Champlain and the Great Lakes. Anglers will be asked to collect marked sea lampreys from their catches, providing valuable data for researchers.
