Researchers analyzed data from the World Health Organization and found that countries with quicker control measures had lower fatality rates and slower epidemics. The study suggests that better control measures, such as rapid hospitalization and isolation of cases, are more effective than differences in infectivity or virulence.
A study by Saint Louis University School of Public Health found that parents who received nutrition information ate more fruits and vegetables, consumed less fat, and had a greater impact on their children's health. The High 5, Low Fat Program aims to deliver consistent messages to young families, promoting healthy eating habits.
Researchers have identified a gene, Nup 96, that plays a crucial role in preventing the reproduction of hybrid fruit fly species, suggesting natural selection as the driving force behind their divergence. The study provides unprecedented insight into speciation and offers new avenues for understanding the evolution of genetic traits.
Scientists have identified a preference for insertion at the beginning of genes and near actively expressed genes, which may explain why gene therapy patients developed leukemia. The discovery could lead to improved gene therapy techniques that insert genes in less risky areas.
Researchers found that intravenous infusions of human umbilical cord blood stem cells delayed ALS disease progression by at least two to three weeks and improved survival in mice. The cells also circulated to organs outside the central nervous system, suggesting an immune-protective mechanism.
The study reveals that renal amyloidosis is associated with a poor prognosis in patients with Familial Mediterranean Fever. AA amyloidosis is a chronic and fatal disease marked by the deposit of amyloid fibrils in the kidney, leading to organ dysfunction and death.
Researchers at NC State and Oak Ridge National Laboratory have successfully tuned the atomic-level zone between substances, opening the way for smaller, faster and smarter computers. By manipulating the electronic dipole charge at the interface, they've found a way to overcome the limitations of Schottky barriers.
A recent meta-analysis has found that vitamin E and beta carotene supplements do not reduce the risk of cardiovascular disease or death. The analysis analyzed data from seven trials involving over 1000 participants, concluding that these supplements may even increase mortality rates.
A new blood test can detect heart attacks in just five minutes with a 99% accuracy rate, improving diagnosis and treatment outcomes. The test identifies two proteins associated with the earliest stages of a heart attack, reducing unnecessary hospital stays.
Developed by Z-Medica Corporation and funded by the Office of Naval Research, QuikClot has been proven effective in treating severe arterial hemorrhage with a high success rate. The product is set to be released for consumer use this summer and may also help individuals with specific bleeding disorders.
A new Northwestern University study suggests a fundamental difference in men's and women's brains and arousal patterns. Women exhibit a bisexual arousal pattern, responding equally to both male and female erotica, unlike men who respond consistently with their sexual orientations.
Researchers studied business models adopted by European mobile operators, finding that interfirm networks offering content services can provide a competitive advantage. The study explores three models and their impact on the role of customers and content providers.
A large prospective study of over 6,300 patients found no significant difference in postoperative complications between obese and non-obese individuals. Obesity alone does not appear to be a risk factor for postoperative complications, contrary to previous attitudes.
Seroquel was shown to significantly reduce mean Young Mania Rating Scale (YMRS) total scores in patients with bipolar disorder, with a faster reduction in symptoms compared to placebo. The medication was well-tolerated and had fewer side effects than other treatments like haloperidol.
Researchers at Frankfurt University Medical School have assessed the antiviral potential of five drugs against the SARS coronavirus. Glycyrrhizin, an antiviral agent proven to treat HIV-1 and hepatitis C, is the most active compound in inhibiting replication, with increased nitric oxide synthesis contributing to its effectiveness.
A recent study by Colorado University-led researchers highlights the growing health risks associated with changes in the global nitrogen cycle. The excessive use of nitrogen fertilizers has led to increased crop production in poor nations but poses significant environmental and health concerns for humans worldwide.
A study led by Rory Collins found that statin therapy reduces the risk of primary outcomes for people with diabetes, including cardiac death, non-fatal heart attack, and stroke. The reduction in risk appeared to be greater among diabetic patients who did not have occlusive arterial disease.
Researchers at Johns Hopkins Medicine reveal the crucial last step involved in long term depression, a process thought to underlie learning and memory. By blocking this step, they created a mouse with weakened connections that didn't affect behavior, paving the way for studying GluR2's role in motor skills.
Researchers have developed a smart brick that can monitor a building's temperature, vibration, and movement, providing vital information for firefighters and rescue workers. The device uses sensor fusion, signal processing, and wireless communication to report conditions remotely, enabling improved safety and comfort.
Acer's process creates a micro-porous calcium phosphate coated polymer 'bone' that allows natural bone growth, reducing recovery time to 18 months. The technology, funded by the Navy Small Business Technology Transition program, has shown success in animal testing and tissue cultures.
Researchers have developed a portable CT scanner that enables real-time, on-site analysis of gas hydrates in core samples, revolutionizing the search for alternative energy sources. The innovative system uses a medical CT scanner and reduces its size to analyze hundreds of x-ray scans into one high-resolution image.
A brain imaging study found that negative emotional states can override logical thinking in economic decisions, such as the ultimatum game, where people are offered a portion of $10. The study reveals a complex interplay between emotion and deliberative thought, suggesting that emotions play a primary role in decision-making.
Scientists discover that cellular senescence involves packaging of specific chromosomal regions into heterochromatin, which triggers a 'stop growing' response in cells. The study reveals genes are switched on in proliferating cells but silenced during senescence.
The discovery of Homo sapiens idaltu fossilized skulls in Ethiopia confirms modern humans originated in Africa and predate Middle Eastern remains by 30,000 years. The ancient predecessor's diet included hippopotamus, with stone tool marks suggesting early mortuary practices and possible scavenging.
Researchers at Louisiana Tech University are developing handheld computers to gather real-time data on patients' psychological states. This innovative approach aims to provide more accurate diagnoses and better treatment decisions.
A UK multi-centre randomised trial found that statins reduce the risk of heart attacks, strokes or revascularisation operations by about a third in diabetic patients, irrespective of their cholesterol levels. This could prevent at least 10,000 heart attacks, strokes and revascularisation operations each year worldwide.
