In contrast, a lower brain volume was observed in patients who received intensive blood pressure-lowering therapy.
Elsevier has launched a new open-access journal called MethodsX, which provides a platform for researchers to publish their customised methods without the need for full research articles. This initiative aims to save time and money for scientists by making it easier to discover and build upon existing techniques.
Researchers found that malignant astrocytoma patients with the IDH1 mutation benefit greatly from surgical removal of as much tumor tissue as possible. This approach significantly improves survival, with average patient survival rates of 13.5 years for those with mutant tumors compared to less than 1.5 years for non-mutant tumors.

A new study by UCLA researchers found that certain pesticides inhibit an enzyme called ALDH, which converts toxic aldehydes into less harmful agents, increasing the risk of Parkinson's disease. The study identified 11 pesticides that increase the risk, particularly in individuals with a common genetic variant of the ALDH2 gene.
Johns Hopkins surgeons have developed a new technique to replace bone removed from the skull after brain surgery, resulting in fewer complications than standard restoration. The approach causes less harm to the brain and reduces infection risk by providing access to blood supply from both top and bottom.

A Harvard University study found that cows which gestated back-to-back daughters produce as much as 1,000 pounds more milk than those that give birth to sons over the first two lactations. This could lead to significant economic benefits for U.S. dairy farmers if artificial insemination techniques are used to increase female calves.
A Johns Hopkins study found nearly half of HIV-infected teenagers and young adults delay treatment until their disease is advanced, putting them at risk for serious infections and long-term complications. Males and members of minority groups are more likely to show up in clinic with advanced infections.

A study found that non-invasive prenatal testing (NIPT) detected over 83% of chromosomal abnormalities, including trisomies 13, 18, and 21. The test was more accurate for women over 40, but had lower sensitivity for younger women.
A study found remifentanil patient-controlled analgesia to be less effective in managing pain relief during labor compared to epidural analgesia. The study, which involved 709 women, showed that patients who received remifentanil patient-controlled analgesia had lower pain appreciation scores and overall satisfaction with pain relief.
A new study by University of Toronto researchers finds that reported oil sands emissions of hazardous air pollutants are greatly underestimated. The team's comprehensive modeling assessment indicates that evaporation from tailings ponds may introduce more pollutants into the atmosphere than direct emissions.
A study of over 1,700 premature babies found that about one in five had cerebral palsy or neurologic impairment by age 2. Babies with serious complications in the NICU also had a higher risk of these conditions.
A study by Cornell University found that weight loss and gain cycles follow a weekly pattern, with participants losing weight on weekdays and gaining weight on weekends. The results suggest that weight fluctuations are normal and can be managed through mindful eating habits.
