A five-year study by University of Utah biologists reveals that giant whales split into three species around 5-6 million years ago, and all three were equally abundant before whaling reduced their numbers. The study used the genetics of whale lice to track the genetic evolution of whales.
The TAXUS V trial found paclitaxel-eluting stents significantly reduced angiographic restenosis and target vessel revascularization rates. The study's results support the use of these stents for patients with more complex coronary lesions, reducing the risk of artery re-narrowing after angioplasty.
The partnership aims to stimulate and accelerate European research into beta cell function and survival, aiming to move towards a cure for diabetes. Approximately 194 million people worldwide suffer from diabetes, with the number expected to exceed 333 million by 2025.
A wire injury from jumping on a bed can be more than just a minor knock on the noggin, according to Dr. Dante Pappano. He published a case study in Pediatric Emergency Care journal after discovering that a mattress wire snapped inside a Rochester boy's foot, leading to a serious injury.
A randomized trial found that high-dose radiation therapy reduced the risk of prostate cancer recurrence by 49% compared to conventional-dose therapy. The study showed improved biochemical control and local tumor control without significant differences in overall survival rates or adverse effects.
A study of over 16,000 participants found a graded association between high blood glucose levels and increasing coronary heart disease risk. Non-diabetic individuals with elevated HbA1c levels were at significantly increased risk of heart disease.
Researchers in Italy found that low pathogenic avian influenza strains can infect humans, highlighting the importance of improving disease surveillance and vaccination for poultry workers. The study suggests these less virulent strains have the potential to swap genetic material with human strains, resulting in a more virulent virus.
A team of scientists, led by Henry Howe from the University of Illinois Chicago, will conduct a multi-year test to restore diversity to agricultural landscapes in Veracruz, Mexico. They aim to demonstrate that bird- and bat-dispersed seeds can connect isolated tree species, promoting species diversity.
The study found a significant decrease in age-standardized death rates from heart disease (52%), stroke (63%), and accidents (41%) since the 1970s. However, death rates from cancer, COPD, and diabetes increased over the same period, despite improvements in detection and treatment for chronic diseases.
A study by University of Michigan researchers reveals the critical genetic switch that allows preadipocytes to become full-blown fat cells, highlighting the importance of balance in fat production. The discovery sheds new light on the role of integrin alpha 6 in regulating fat cell formation and its potential link to metabolic disorders.
Scientists at NIST confirm improved accuracy of 'watt balance' method, reducing measurement uncertainty by about 40 percent, moving closer to redefining the kilogram in terms of basic properties of nature.
Studies show that high back booster seats provide a 58% reduction in injury risk to children aged 4-8, while increased rear row occupancy reduces risk by up to 58%. Children riding in passenger cars and light trucks face increased risk of serious injury in side-impact crashes.
The National Institute of Environmental Health Sciences (NIEHS) has awarded $37 million to train emergency and hazardous waste workers. The grants will fund five training programs: Hazmat Disaster Preparedness, Hazardous Waste Worker Training, Department of Energy Nuclear Weapons Cleanup, Minority Worker Training, and Brownfield Minori...
A study found that heart failure patients with high predicted risk of death within a year are less likely to receive appropriate medications, including ACE inhibitors and beta-adrenoreceptor antagonists. The researchers suggest underappreciation of therapy benefits and multiple comorbid conditions may contribute to the treatment mismatch.
Cardiac stress testing reveals a significant association between exercise capacity and heart rate recovery with CHD mortality rates. The study found that asymptomatic individuals with below-average test scores were two to four times more likely to die from CHD within 10-20 years.
A study found that HIV-infected patients with mild memory loss who used the Disease Management Assistance System (DMAS) Jerry took their medication 80% of the time, compared to 65% without it. This improvement was seen in both normal and memory-impaired patients.
Researchers found that reported insurance status significantly influences access to follow-up appointments for urgent ambulatory care. Privately insured patients were more likely to receive appointments within a week compared to those with Medicaid or no insurance, suggesting a barrier to timely care.
Researchers found that a decline in prostacyclin led to cardiac complications, including hypertension and heart scarring, in mice prone to high blood pressure. Aspirin may protect against this damage by blocking unrestrained thromboxane actions.
Researchers will investigate how patient cost-sharing affects health care law, medical ethics, and the doctor-patient relationship. The study aims to better understand the impact of consumer-directed initiatives on these areas.
A new study reveals that tropical deforestation affects rainfall in the US and around the globe, with significant changes observed in various regions. Deforestation in Amazonia influences precipitation in Mexico to Texas, while Central Africa affects the US Midwest, and Southeast Asia alters rainfall in China and the Balkan Peninsula.
A new single-dose ciprofloxacin treatment has been shown to be effective in treating childhood cholera, with 60% of cases cured within 48 hours. However, the new treatment is less effective at eradicating the cholera bacteria from stool compared to a 12-dose course of erythromycin.
The Gladstone Institutes' team supplied original stem cells for the exhibit and trained museum staff on techniques to activate cells. The exhibit showcases the development of cardiac myocytes from undifferentiated state to pulsating heart cells.
A new study using NASA satellite images found that MODIS can detect changes in Amazon land cover rapidly and reliably. This technology allows for regional analyses of land cover in a matter of days, reducing the time required for analysis compared to high-resolution Landsat data.
A new study found that mice with high blood pressure are more susceptible to cardiac complications when taking painkillers due to a chemical imbalance between prostacyclin and thromboxane. This imbalance can lead to hypertension, enlarged hearts, and severe scarring of the heart.
A study published in Nature Neuroscience reveals that AgRP neurons play a crucial role in regulating eating behavior and body weight. The research found that these neurons are essential for acute regulation of eating, and their destruction leads to anorexia and changes in blood glucose levels.
