Researchers found a clear association between increased DDT concentrations in maternal blood and decreased chance of pregnancy in daughters. The opposite effect of DDE concentrations was unexpected, but may explain the lack of large changes in human reproductive performance after DDT introduction.
A new study reveals that bone morphogenic protein-7 (BMP-7) can reverse chronic kidney injury by reducing scar tissue and repairing damaged areas. This breakthrough could lead to a cost-effective treatment alternative for patients currently undergoing dialysis, significantly improving their quality of life.
A recent study by the American College of Emergency Physicians found no significant racial differences in the administration of pain medications to children, but did reveal regional variations. Children in the South and West received narcotics more frequently than those in other parts of the country.
A two-thirds reduction in childhood deaths is achievable in 42 countries with 90% of child deaths if known low cost measures such as breastfeeding and vaccination are extended to maximum coverage. The primary challenge today is to transfer what we already know into action.
The study found that uninsured patients and Medicaid recipients account for a significant proportion of emergency department visits due to tooth pain or injury. Despite receiving antibiotics or pain medication, these patients often lack follow-up dental care.
Researchers have discovered a nickel-tin catalyst that can replace precious metal platinum in producing hydrogen fuel from plants. The new catalyst, combined with a hydrogen purification innovation, offers opportunities for transitioning to a world economy based on renewable resources.
Researchers have identified a new target for treating female sexual dysfunction, which is caused by an enzyme that disrupts blood flow. The discovery provides an important advance in understanding the biochemical cascade involved in healthy sexual function.
A new study reveals the global spread of a virulent dengue virus strain responsible for severe disease outbreaks in Latin America and Africa. The research uses viral genetics to demonstrate the virus's movement from Asia and Africa to the Americas, shedding light on its emergence and transmission.
Scientists have determined the structure of the 2G12 antibody, which neutralizes HIV by binding to sugars on its surface. The antibody's unique structure could provide a template for designing an antigen that triggers the body to produce it, potentially leading to an HIV vaccine.
Researchers chart seismic effects on water levels to better understand the impact of earthquakes on hydrology. The study found that wells and aquifers respond differently to earthquakes than surface water, with effects recorded at greater distances.
Research reveals that amyloid accumulation selectively reduces expression of genes essential for forming new memories, leading to early memory loss in Alzheimer's disease. The study suggests a new approach to treating the disease by blocking the effect of remaining amyloid on normal learning and memory.
According to a study by Johns Hopkins Bloomberg School of Public Health, China loses an estimated 12 million productive working years annually due to injuries. The economic burden is substantial, with motor vehicle crashes, suicide, and falls accounting for the majority of productivity lost.
Children who consumed more than 12 ounces of sweetened drinks gained significantly more weight than those who drank less, due to increased caloric intake. The study also found that sweetened drinks displaced milk consumption, leading to lower calcium and zinc intake.
Researchers are conducting critical infrastructure modeling and assessment to improve public safety. They analyze the connections between infrastructures, such as traffic lights and power plants, to anticipate potential failures. The project creates data visualizations to help policymakers understand the big picture.
A new study found that alcohol consumption increases the activity of a protein that causes the hepatitis C virus to replicate, leading to liver disease. The study also discovered that alcohol interferes with antiviral treatment, such as interferon-alpha, which is currently the only licensed treatment for the infection.
A study by Cornell University found that smoke-free regulations in New York restaurants and hotels did not harm employment or sales. In fact, the regulations led to a statistically significant increase in taxable sales and overall payrolls.
Researchers at TSRI describe an unusual antibody configuration that effectively neutralizes HIV by binding to sugars on its surface. This breakthrough could lead to designing an effective AIDS vaccine by stimulating the human immune system to produce similar broadly neutralizing antibodies.
Studies found that increasing TBP levels can contribute to oncogenesis, while p53 acts as a tumor suppressor by reducing TBP's effective concentration. These findings have implications for the development of new cancer treatments and therapies.
Research found that alcohol consumption increases hepatitis C virus replication by upregulating nuclear factor kappa B, a key cellular regulator of immune pathways. Alcohol also inhibits the anti-HCV effect of interferon-alpha therapy. Treatment with naltrexone abolishes alcohol actions.
Researchers exposed eight healthy participants to hypoxia and normal air conditions to investigate potential link between air travel and venous thrombosis (DVT). The study found no significant changes in clotting activity during hypoxic exposure, but a larger study is required to confirm these findings.
A new study connects a powerful cancer-causing protein to a gene associated with Werner syndrome, a disease causing premature aging. Researchers suggest developing drugs that interfere with the WRN gene's anti-aging properties to block Myc's tumor-promoting activity.
Researchers have developed a new catalyst that can produce hydrogen at lower temperatures and with reduced greenhouse gas emissions compared to traditional methods. The catalyst, based on nickel, tin, and aluminum, has the potential to be used in industrial applications such as fertilizers production and petroleum products processing.
A study of 239 heart-attack victims reveals that African Americans waited significantly longer than non-Hispanic whites to receive treatment, with blacks delaying by over three hours and whites by two hours. This delay can lead to reduced mortality rates if treatment begins within an hour after symptoms onset.
A study by Purdue University researchers found that patients experience more improvement in quality of life when taking more expensive pharmaceuticals, regardless of the ailment. The study suggests that government interference with market prices may reduce long-term drug development and potentially lead to fewer quality drugs.
Researchers engineered bacteria to produce bixin, a plant product used in foods and cosmetics, by replicating the plant's biosynthetic pathway. The genetically modified E. coli can produce the same compound as the natural source, providing an alternative for expanding supply and addressing challenges in non-biological synthesis.
A study published in The Lancet found that law enforcement can substantially reduce fatal traffic crashes by 35% lower risk of fatalities after a conviction. Enforcement policies, including penalty points for driving convictions, show greater reductions in fatal crashes than mandatory vehicle improvements.
