A recent study by Vanderbilt researchers found that high levels of estrogen can alter the expression of genes related to implantation in mice, leading to a reduced window of receptivity for embryo implantation. This could be contributing to high implantation failure rates in women undergoing IVF.
Dr. Salzman, a Columbia University professor, has been awarded the Charles E. Culpeper Scholarship in Medical Science from the Rockefeller Brothers Fund. The award will support his research on understanding emotion and developing new treatments for psychiatric illness.
The biogerontological community is at war with anti-aging medicine, threatening the status and funding of their own research. Binstock argues that this campaign may inadvertently undermine their own legitimacy and research support by blurring public understanding of the difference between their work and pseudoscientific products.
Researchers found that low-level lead exposure during development in mice injures and kills rod-shaped photoreceptor cells, a crucial component of human vision. The study suggests possible treatments using an anti-death protein called Bcl-xL to prevent cell death in eye disorders.
Scientists at Thomas Jefferson University found that a bacterial toxin opens a cellular door, allowing calcium to flow into tumor cells, which slows cell division and may lead to new methods of treating colorectal cancer. The discovery could also enable the use of the toxin as an intravenous infusion to treat metastatic tumors.
The main cause of tooth discoloration lies at the surface of enamel, where red wine, coffee and tea stain teeth. Hydrogen peroxide-based whitening agents target deeper discoloration by forming radical intermediates that break down into water and oxygen.
A study by Ohio State University found that minorities are more likely to question police during traffic stops, with black men reporting a 35% higher rate of stops than white men. The study also found significant differences in how black and white drivers perceive their treatment by police.
The study found a 92% decline in risk of future Exxon Valdez-like spills after implementing risk management measures. The Prince William Sound team estimated the probability of accidents involving oil tankers and identified key risks, such as tanker collisions with fishing vessels.
Researchers discovered that many nonagenarians (people 90-99 years old) are free of Alzheimer's disease or dementia, with some performing in the superior range on cognitive tests. Mild cognitive impairment (MCI) also exists in this age group, but features similar characteristics to those seen in younger individuals.
The Falk Center will utilize state-of-the-art gene chip technology to identify genes responsible for neurological disorders. Two therapeutic developments are approaching the product stage, including a gene-based therapy for malignant brain tumors and a treatment for attention deficit hyperactivity disorder.
Researchers found that more than 1.5 million Americans suffer from celiac disease, which is triggered by the protein gluten and can cause various gastrointestinal symptoms. The study, published in Archives of Internal Medicine, used a multi-center approach to screen over 13,000 people across 32 states.
The new guidelines provide recommendations for evaluating children with global developmental delay, including the use of cytogenetic studies and molecular testing. Early diagnosis can help determine the cause of the disorder and assist in developing a treatment plan.
Researchers found that people with a family history of colon cancer were more likely to have high-risk diets, including cooked red meat and low folate levels. Modification of these factors could provide broad benefits for individuals with a family history, regardless of their genes.
Researchers found that intermittent fasting reduced degeneration of nerve cells and improved glucose regulation in mice with mutant huntingtin. This suggests that fasting may forestall the development of Huntington's disease in humans.
A University of California, Irvine study found that sea-salt chlorine reactions can raise ozone levels by up to 10% in Southern California smog. This could lead to increased pollution in coastal regions, with predicted ozone levels exceeding national standards on certain days.
The new mat mimics natural clotting processes by creating fibers of similar dimensions to those found in the body. It can be used for minor cuts or severe battlefield wounds, promoting clotting and eventual absorption by the body.
OptIPuter program to deploy DiamondWave all-optical switches, enabling fast and cost-effective network with high-speed data transmission. The platform will support scalable and flexible network infrastructure with minimal signal power loss and latency.
Actonel significantly reduced fracture risk in high-risk postmenopausal women, with a 62% reduction seen at one year. The medication was found to be effective in reducing spinal fractures in patients over 70 years old and those with low hip BMD.
A Purdue research report suggests that ancient lake sediments and computer simulations indicate El Niño might react differently to global warming than current theory claims. The tropical Pacific Ocean maintains its ability to remove heat periodically, even when the climate warms.
Scientists have found that Bacillus spore size changes with environmental conditions, potentially allowing for rapid detection of anthrax. The discovery could enable a test to identify anthrax spores in seconds to minutes.
Researchers discovered that giant solar loops can erupt explosively, releasing massive amounts of plasma and heat. The longer the loop, the more likely it is to erupt, posing a threat to satellites and space weather.
