The researchers found that mice lacking FoxO genes had serious blood abnormalities, including rapid division and depletion of stem cells.
A survey of 4,839 West Australian women found nearly 80% consumed alcohol in the three months before pregnancy, with more than half drinking during pregnancy despite recommendations. The study highlights the need for effective health promotion messages to reach women of child-bearing age.
Researchers at UC Davis have created luminescent, magnetic nanoparticles that can be used for tests of environmental pollution and contamination in food products. The particles can also be labeled with antibodies or DNA for genetic analysis, and have the potential to revolutionize medical diagnostics.
Research suggests that brown algae polyphenols (BAPs) extracted from a marine seaweed can reduce the number of skin tumors by up to 60% and their size by up to 43%. The substances also reduced inflammation, with lower levels of COX-2 and prostaglandin E2 detected in BAP-treated animals.
A team of researchers has discovered a unique hybrid species of butterfly in the Sierra Nevada mountains, with genes from both parent species. The study suggests that natural selection played a crucial role in its evolution, highlighting the importance of understanding how animal species emerge.
A recent USC study reveals that children who live within 500 meters of a freeway have substantial deficits in lung function by age 18 compared to those living farther away. This highlights the importance of reducing exposure to traffic pollution for healthy lung development.
A new unified score, ABCD², has been developed to predict stroke risk within 2 days of TIA more accurately than existing scores. This improvement can help guide clinical decisions and optimize secondary prevention strategies.
A $1 million grant will fund a five-year study using bioremediation to promote bacterial growth in soil subsurface, scrubbing radioactive metal. This method has the potential to clean up an estimated 1.7 trillion gallons of contaminated water and 40 million cubic meters of contaminated soil nationwide.
Researchers used MRI to detect macrophages in arterial walls, which indicate inflammation and cardiovascular disease. The study found a 79% increase in detection compared to baseline images, suggesting a potential noninvasive screening tool for heart attack risk.
Researchers at the University of Texas Medical Branch discovered a potential method to prevent failed back surgery syndrome (FBSS) by applying a local anesthetic, Lidocaine, to the exposed spinal cord before surgery. The technique successfully blocked the release of chemicals associated with FBSS and reduced sensitivity in rats.
An observational study published in The Lancet found that thrombolytic drug alteplase is safe and effective in routine clinical use when used within 3 hours of stroke onset. This suggests that intravenous treatment with alteplase could be considered as part of routine care for suitable stroke patients.
Researchers found that a key protein is crucial for pneumonic plague's development. Disabling this protein slows the deadly attack, potentially giving doctors time to administer antibiotics and save patients.
A new strategy for fighting cancer aims to make its genes get lost in translation, silencing oncogenes by targeting weak messenger RNAs. The researchers discovered a small molecule that effectively inhibits the translation of these weak mRNAs, leading to the decline of cancer-promoting proteins.
A new study has found that the ADH1B*3 allele appears to protect against alcoholism in Afro-Trinidadians, while increasing the risk for liver disease among those who drink heavily. Individuals with this allele have lower alcohol consumption levels and are less likely to be alcohol-dependent.
Researchers at Cedars-Sinai Medical Center successfully cultured stem cells from human bone marrow that can differentiate into neurons and other central nervous system cells. These cells exhibit behaviors similar to those derived from brain tissue, suggesting a promising approach for treating brain disorders and tumors.
