A study found that nearly 80 high-risk cardiovascular devices received FDA approval based on data from a single study, highlighting the need for high-quality research. The review of 123 summaries of safety and effectiveness data revealed discrepancies between enrolled and analyzed patients, which may introduce bias.
A recent study developed a straightforward technique to determine the ethnic origin of stem cells, finding that Caucasian and East Asian populations are overrepresented in current cell lines. The team created a new stem cell line with a West African Yoruba genetic profile, which could lead to more diverse research and safer therapies.
The MIRI detectors will enable the Webb telescope to observe the earliest stars and galaxies in the universe, allowing scientists to study the formation and evolution of the cosmos. The new video showcases the technology behind MIRI and its potential for groundbreaking discoveries.
A study by Dr. Gregory A. Elder found that presenilin-1 plays a role in the vascular pathology associated with Alzheimer disease, while another study discovered that osteopontin contributes to allergic contact dermatitis. Weakened Plasmodium parasites also elicit a protective immune response.
A study published in JAMA found that telemedicine for ICU patients was not associated with improved mortality rates, length of stay, or reduced illness and death. Tele-ICU systems were only beneficial for sicker patients.
A new study has found that chlorophyll and its derivative chlorophyllin are effective in limiting the absorption of aflatoxin in humans. The Phase 0 approach allows for the measurement of minute amounts of aflatoxin, revealing rapid absorption that is significantly limited after treatment with chlorophyll and chlorophyllin.
Researchers at Georgetown Lombardi Comprehensive Cancer Center report a significant advance in personalized medicine using a new chip that examines hundreds of genetic mutations. The chip, called DMET, could replace highly-specialized and labor-intensive genotyping tools, accelerating cancer research and treatment.
Scientists find evidence that Arctic Ocean and Nordic Seas may experience seasonally ice-free conditions and much warmer temperatures in the future. USGS research suggests that current climate models underestimate sea ice loss, with potential consequences including accelerated coastal erosion and impacts on polar bears and seals.
Researchers found TRAP-1 to be highly expressed in prostate cancer cells, inhibiting cell death, while Gamitrinib treatment killed cancer cells but not healthy ones. This suggests targeting TRAP-1 may provide a new approach for treating advanced prostate cancer.
Researchers at Medical College of Wisconsin develop rapid semi- and fully-automated multiplex real-time RT-PCR assays for detecting human H1N1, H3N2, and swine-origin H1N1 viruses. The tests can distinguish between influenza A, B, and RSV infections, reducing technician and assay time.
A study published in the Journal of Oncology found that acupuncture is as effective as drug therapy in reducing hot flashes and improving energy and clarity of thought in breast cancer patients. Acupuncture also showed benefits for sex drive and overall sense of well-being, with minimal side effects.
A recent study published in JAMA found that Ginkgo biloba supplementation did not slow the rate of cognitive decline in older adults with normal cognition or mild cognitive impairment. The researchers analyzed data from over 3,000 participants and found no evidence of an effect on global cognitive change or specific cognitive domains.
Researchers create a synthesis technique that generates moving images of 3D objects, which are virtually impossible for computer algorithms to decode. This technology could lead to a better captcha system, highlighting the difference between human and robotic perception.
Pharmacists at the University at Buffalo improved diabetes care for patients with Type 2 diabetes, reducing their A1C levels by an average of 1.1% over six months. This improvement came with significant cost savings, with monthly costs per patient decreasing by approximately $212.
A group of US plant pathologists came together in Boston in 1909 to discuss plant problems and establish a new field of science. Their efforts led to significant progress in diagnosing and controlling plant diseases, benefiting the US agriculture industry.
Researchers use new acoustic sensors to monitor endangered North Atlantic right whales and reduce ship strikes, a leading cause of their deaths. The tools improve monitoring capabilities and enhance management efforts to protect these whales.
Research from the Kellogg School of Management explores 'moral hypocrisy' in powerful individuals, finding that power makes them stricter in moral judgment of others while being less strict of their own behavior. Power also leads to a disconnect between public judgment and private actions.
A study by the Center for Studying Health System Change reveals a gap between policy makers' expectations of commercial EMRs to improve care coordination and clinicians' real-world experiences. Current EMRs facilitate care coordination within practices but struggle with exchanging information across physician practices and settings.
Researchers will investigate the role of vortices in normal and abnormal voice production, with a focus on unilateral vocal cord paralysis. The goal is to develop effective treatments that restore vortices and normalize vibrations.
The new series aims to address the shortage of geriatric expertise in healthcare. The series will explore themes that develop with aging, such as frailty and loss of independence. By analyzing real stories of patients and interviews, it will provide clinicians with pragmatic tools for translating evidence into daily practice.
CU-Boulder is leading a $3.3 million concept study for a lander mission to Venus, aiming to study the planet's surface, climate, and atmosphere. The mission will compare Venus with other terrestrial planets and help understand Earth's fate.
