A new study by Johns Hopkins Medicine suggests that prolonged hypothermic circulatory arrest (HCA) can cause an overproduction of glutamate, leading to increased risk of brain damage. The study found significant increases in glutamate levels during the cooling process, recovery period, and up to eight hours post-recovery.
A major European study found that an antioxidant compound called lycopene in tomato sauce appears to have a protective effect against heart attacks. The study showed men with high lycopene consumption had about half the risk of heart attack compared to those with low lycopene consumption.
Researchers found that combining ganciclovir eye implants with oral ganciclovir reduces the risk of new CMV disease, Kaposi's sarcoma, and extraocular complications in AIDS patients. The study also showed a delay in median survival time among those receiving combined therapy.
Diane Waddle and her team discover a vast collection of fossils, including those of tiny bats, shrews, birds, frogs, adult and juvenile primates, in the Bone Cave in Botswana. The find is significant as it helps fill the gap in the fossil record of Botswana.
Scientists have identified a new genetic risk factor for late-onset Alzheimer's disease, accounting for up to 15% of cases. The gene located on chromosome 12 works independently of the previously discovered ApoE gene, which accounts for half of all patients with the disease.
A study by Colorado State University researchers found that white adolescent males are more receptive to beer ads with sports-related themes, while females respond negatively. The study also showed that adolescents who responded positively to beer ads were more likely to use alcohol as adults.
Researchers developed an iNOS gene therapy that prevents chronic organ rejection and transplant arteriosclerosis in animal models. The study found that the gene therapy suppressed the disease process by triggering production of nitric oxide, which blocks blood flow in transplanted organs.
Researchers at University of Washington identify decades-long climate shift in Pacific Ocean called PDO, influencing US West Coast ocean temperatures, winters, and salmon harvests. The current positive phase explains recent record highs in Alaska salmon and wetter winters in the South.
Researchers have identified a genetic risk factor for late-onset Alzheimer's disease, combining the E4 variant of apolipoprotein E with the butyrylcholinesterase K variant. This combination significantly increases the risk of developing Alzheimer's disease in people over 65 years old.
