A study published in the Journal of Clinical Investigation found that HIV protease inhibitors directly promote atherosclerosis in mice. In humans, researchers propose a mechanism by which these drugs might contribute to heart disease, suggesting ways to disrupt it.
A recent study by Ohio State University reveals that chronic self-doubters are more prone to anxiety, depression, and procrastination. They tend to lack confidence in their decision-making abilities, leading to a vicious cycle of self-doubt.
Researchers found that HIV protease inhibitors directly promote atherosclerosis in mice by inducing changes in macrophages. A commentary article proposes a mechanism and suggests ways to disrupt this process. The study has significant implications for the long-term use of these drugs in managing chronic HIV infection.
A study found that many doctors' offices struggled to consistently obtain enough Prevnar vaccine, with over half reporting they had run out completely in the past year. The nation's 'patchwork' system of vaccination, driven by varying state practices and private insurance, contributed to these inconsistencies.
Researchers found no difference in life expectancy between single- and multiple-fraction radiotherapy for painful bone metastases. Single-fraction radiotherapy is more cost-effective, with a lower treatment cost of $2,438 compared to $3,311 for multiple-fraction radiotherapy.
Researchers have found that bone marrow cells from transplants can relocate to brain tissue, carrying Y chromosomes into Purkinje cells involved in balance and movement. This discovery suggests that these cells may act as a repair squad to treat damaged tissues throughout the body.
Researchers found that selenium supplements reduced DNA damage in elderly male dogs' prostates, potentially benefiting aging prostate health. A separate study suggests a new retinoid treatment may prevent lung cancer in former smokers by restoring RAR-ß expression and reducing squamous metaplasia.
A study of 95 premenopausal women found a significant link between low estrogen levels and an increased prevalence of coronary artery disease. Women with hypoestrogenemia were more likely to experience adverse coronary arterial dysfunction, suggesting a higher mortality risk.
A team of researchers led by Michael R. Brent developed a new computer program to predict genes by analyzing patterns of evolutionary conservation. They identified 1,019 predicted novel mouse genes with high accuracy, including those involved in Duchenne muscular dystrophy and neural development.
A recent Ohio State University study found that computerizing physician orders reduced medication turn-around times by 64 percent, X-ray procedures by 43 percent, and lab tests by 25 percent. This led to improved work flow, efficiency, and accuracy in patient care.
Researchers at North Carolina State University have successfully produced all-female cultured stocks of Southern flounder using controlled-breeding methods and warm water temperature manipulation. This method has significant economic potential, as female flounder can grow up to two times larger than males within two years.
Researchers identified BRCA2 germline mutations in 19% of families with familial pancreatic cancer. The presence of specific frameshift mutations was found in 12% of the families studied. These findings suggest an important role for BRCA2 mutations in a subpopulation of families with familial pancreatic cancer.
Researchers found that mindfulness meditation increased activity in the left side of the frontal region, associated with lower anxiety and a more positive emotional state. The meditation group also showed a significantly larger increase in immune function compared to the control group.
Individuals with reduced functional Artemis protein are prone to mild immunodeficiency and increased risk of developing lymphomas. This finding suggests that mutations in Artemis or other DNA repair genes may be responsible for immune deficiency and/or lymphoma cases.
Researchers found that a vitamin A derivative, 9-cis retinoic acid, increased RAR-_ gene expression and reduced precancerous lesions in former smokers. While promising, the treatment also showed side effects, and further studies are needed to determine its effectiveness.
The new Civil War Newspapers website will feature scanned documents of selected newspapers from both North and South, providing detailed indexes and a comprehensive master index. This project aims to provide a valuable resource for historians, allowing them to access a vast amount of information on various topics related to the era.
Researchers at Duke University Medical Center found that older divers remain healthy enough to dive safely as long as they do not have any underlying lung or heart conditions. The study used hyperbaric chambers to measure the effects of carbon dioxide retention on older and younger divers.
Researchers have identified a new gene, endothelial lipase (LIPG), that regulates HDL cholesterol levels and impacts the risk of developing heart disease. By altering LIPG expression in genetic models, scientists found an inverse relationship between HDL cholesterol and EL expression.
Researchers at UT Southwestern are developing a new procedure to eliminate graft-versus-host disease in bone-marrow transplants while retaining anti-leukemic activity. The approach uses immunotoxins to selectively target and eliminate harmful immune cells, with promising results in clinical trials.
A study found that colonoscopy perforation rates are twice as high as those of sigmoidoscopy. The risk of perforation from sigmoidoscopy was about half that of colonoscopy, with 5% of perforations resulting in death within 14 days.
Researchers found depression before surgery significantly increased hospitalization for cardiac reasons six months post-operative, with patients experiencing prolonged surgical pain and failure to return to normal activities. Depression also persisted post-surgery, often unrecognized and untreated.
A new report by Newcastle University and Sunderland University found that many male soldiers and officers still struggle with adjusting to the presence of women in the organization. Women are often portrayed as a disruption or sexualized in media images, influencing Army perceptions and policies.
A study by Ohio State University found that children living in owned homes outperform those in rental units, with higher math and reading achievement scores. The researchers attribute this difference to the better home environment, including safety, maintenance, and educational materials.
A study of 61 patients with HIV-related peripheral neuropathy found that psychotherapy reduced pain intensity and improved daily life functions. However, high dropout rates and short attendance periods made it challenging to assess the treatment's effectiveness.
A study published in the Journal of the American Medical Association found that faceguards reduced facial injuries by 35% and safety balls cut ball-related injuries by 29%. The research analyzed over 6.7 million player-seasons of Little League participation, making it the largest and most comprehensive study of its kind.
