Researchers identified 80 genes in the blood-brain barrier activated by Group B Streptococcus, a leading cause of bacterial meningitis. These genes triggered an immune response by mobilizing neutrophils to combat infection.
A study of 2,343 men and women found that infrequent heavy drinkers had more abdominal fat than regular consumers. Moderate drinking was associated with smaller waist sizes, while binge drinking led to higher abdominal measurements.
A Mayo Clinic study found that 69% of mothers and 58% of fathers reported having distressing thoughts about their infant's safety. New fathers struggle with obsessional thoughts, which can be a sign of an underlying issue that requires professional care.
A new study has found that a phone support group program helps older adults with HIV/AIDS develop coping skills, reducing stress and suicidal thoughts. The 12-week telephone intervention program appealed to participants who faced barriers in accessing traditional support groups or counseling services.
The Annual Report to the Nation on Cancer statistics shows stabilized cancer rates. A study found carboplatin-paclitaxel is better tolerated in ovarian cancer patients than cisplatin-paclitaxel. Another study linked blood transfusions with HHV-8 seropositivity, while HPV status may predict cervical lesion prognosis
Researchers at UNC School of Medicine have identified a novel enzyme that halts histone synthesis when no longer needed, preventing lethal cell damage. The discovery sheds light on the complex regulatory mechanisms governing histone mRNA expression.
Researchers have discovered an engineered mouse that can eat a high-fat diet without gaining weight or developing diabetes. The mouse lacks the SCD-1 gene, which affects fat production and glucose regulation. As a result, muscle cells are more sensitive to insulin, enabling them to absorb glucose and regulate blood sugar levels.
A historic conference at the U.S. Naval Academy brought together experts on underwater rescue and salvage, including survivors of notable submarine accidents like USS SQUALUS and USS TANG.
