A recent study analyzed data from two Finnish cohorts and found the risk of any type of eye injury caused by airbags to be very slight, only 2.5 percent. Open eye injuries were more likely to occur among eyeglass wearers, but those who did not wear eyeglasses were more likely to suffer from injuries caused by airbag chemicals.
A study by Te Velde found that the Pringle manoeuvre increases tumour growth and recurrence after liver surgery, reducing patient survival chances. Medicines preventing blood vessel regeneration can be combined with chemotherapy to control tumours.
Researchers have calculated that internal waves can carry up to 50% of their original energy as they propagate through the ocean depths, with this energy directed towards mid-latitude areas. This finding has significant implications for understanding ocean mixing and its impact on global climate models.
Researchers evaluating environmental impact of common nightcrawler on forest ecosystem in the Northeast. The invasive earthworm species is feeding on leaf litter and duff layers, affecting native plant seeds and animals.
A study by Dr Lydia Plowman and Dr Rosemary Luckin found that young children can coordinate toy and screen interactions without confusion. However, the toys' limited ability to promote learning was noted, with children preferring human helpers over technology.
The Tulane center will prepare and distribute a continuous supply of marrow stromal cells (MSCs) using standardized protocols, addressing the need for standard MSC preparations. The center's availability will allow scientists to better understand the capabilities of these cells for potential therapeutic uses.
A new study by UT Southwestern finds that finasteride effectively reduces prostate cancer risk and improves symptoms in men with benign prostatic hyperplasia. The drug, already used to treat BPH, works by inhibiting the conversion of testosterone to dihydrotestosterone, which is involved in prostate cancer development.
Researchers develop soluble mimics of GPCRs to study their interactions with G-proteins, potentially leading to new drugs for various medical conditions. The technology could also be used to screen for drugs that block malfunctioning GPCRs.
Researchers used computer simulations to study the effect of foreign particles on crystal growth patterns. They found that these particles produced unique 'dizzy dendrite' patterns that can be replicated using specific methods.
The American College of Sports Medicine honors Dr. Mueller, a renowned expert in athletic injury research, for his 35-year dedication to making sports safer. His work has led to significant rule changes, safety equipment updates, and a reduction in injuries and fatalities across various sports.
A University of Washington linguist and the Aleuts will begin a two-year effort to preserve the Aleut language by recording everyday conversations on audio and videotapes. The goal is to document the language, which has declined from 620 speakers in 1990 to just over 100 today.
Researchers from NIST and NREL develop a method to accurately measure the dipole moment of quantum dots, enabling optimization for various applications in quantum computing and quantum communications.
A Lehigh University professor has developed a system that combines images from optical and millimeter-wave cameras to detect concealed weapons, which could save security guards seconds in the search process. The technology uses wireless communication links and has potential applications for law enforcement and military use.
Kenyans rely on mosquito nets to keep mosquitoes at bay, but don't view them as a means of preventing malaria. Insecticide-treated bednets can reduce fatal cases by 20%, but effectiveness depends on consistent use and re-impregnation with insecticide.
Researchers discovered protrusions in oil paintings, composed of metal soaps, which form when paint layers contain lead and zinc. The phenomenon affects both panels and canvases, causing a bumpy surface texture, and can still be active in some cases.
The US patient underwent the second procedure in the revised Phase I human clinical trials at Penn State Hershey Medical Center. The Arrow LionHeart device has shown promising results in lengthening and improving the lives of patients with end-stage heart failure.
Researcher Chris Molenaar developed a method to follow biomolecule movements in living cells, revealing interactions between proteins and RNA. The technique uses fluorescent probes and microscopy to visualize molecular mobility and interactions, providing insights into cell functioning.
Researchers found that 30% of diabetic patients with kidney disease do not exhibit common symptoms like protein in urine and eye disease. The current approach of screening for these symptoms alone is insufficient, and a blood test measuring kidney function directly is recommended.
The Wake Forest Problem-Based Learning Center has received a $539,352 grant from the Howard Hughes Medical Institute to support teacher professional development. The center's program, which uses problem-based learning to engage students in real-world science and math projects, has shown remarkable success, with 97% of tracked students ...
Researchers at the National Space Biomedical Research Institute are developing a new treadmill training system to help astronauts recover from balance problems after long-duration space flights. The system will also aid elderly patients and others with similar issues.
Researchers found that patients with a negative pretransplantation scan had a favorable outcome, with 25 still in complete remission after a median follow-up of 1,510 days. In contrast, patients with a positive scan relapsed more frequently, highlighting the potential for [F]FDG-PET to identify nonresponders.
Researchers used ultrafast light pulses to visualize the speed distribution of electrons in Rydberg atoms, revealing their wave-like behavior. This study provides new insights into the interaction between light and slow-moving electrons.
Researchers at St. Jude Children's Hospital have successfully treated four pediatric patients with retinoblastoma using a combination of chemotherapy, radiation therapy, and stem-cell transplantation. The study shows promising results, with two out of four patients surviving for over six years without disease recurrence.
The EVAP-COND software simulates the performance of evaporators and condensers with various cooling agents, enabling engineers to optimize designs. This tool helps conserve energy while reducing laboratory testing and design-to-production time.
Researchers used acoustic measurements to recognize differences in vowel pronunciation among 160 Dutch and Flemish teachers. The study found that acoustic methods can map sociological differences in pronunciation with high accuracy, outperforming phonetic transcription methods which require manual expert analysis.
Finasteride has been shown to prevent prostate cancer in both low-risk and high-risk men. However, those on finasteride were more likely to develop high-grade cancers.
A ferret protein called glucose-6-phosphate isomerase (GPI) plays a key role in the reproductive process, allowing fertilized embryos to implant successfully. The discovery also sheds light on the mechanism of cancer cells, which can co-opt this process to invade healthy tissues.
Contrast-enhanced MRI is a reliable method to measure blood flow to tumors, allowing for accurate assessment of chemotherapy response and tumor viability. The study found that patients who responded to treatment had significant decreases in angiogenesis, while non-responders showed increases.
The National Institute of Standards and Technology has developed a new instrument to study the metal of World Trade Center (WTC) steel. The apparatus rapidly compresses and heats samples at extremely high temperatures, helping to improve understanding of how steel responds under stress.
Women taking long-term combined HRT face a significant increase in breast-cancer risk, doubling the risk for invasive lobular and ductal breast cancer. The study found that both sequential and continuous progestin regimens were associated with similar increases in breast-cancer risk.
