Levels of gene-expression-regulating enzyme altered in brains of people with schizophrenia

A study using a PET scan tracer has identified epigenetic differences between the brains of individuals with schizophrenia and those of unaffected participants. Reduced histone deacetylase (HDAC) levels were observed in the dorsolateral prefrontal cortex, which is important for executive functions affected by schizophrenia.

UMN medical school researchers study abnormal blood glucose levels of discharged patients

A study by University of Minnesota Medical School researchers found that patients with abnormal blood glucose ranges have a higher rate of hospital readmission and death in the 30 days after discharge. Patients with 'borderline' high glucose levels who are not diagnosed with diabetes also experience worse outcomes.

Correlation of stroke and dementia with death: A study from the Swedish dementia registry

A Swedish study found a significant correlation between dementia and ischemic stroke, with patients dying from IS having a higher mortality rate compared to those who did not have IS. The study also highlights the importance of accurate death certificate diagnoses, particularly for deaths reported outside Swedish hospitals.

Chinese scientists get first look at geometric phase effect in a chemical reaction

Researchers from China and Germany discover the geometric phase effect in a benchmark chemical reaction, providing new insights into molecular systems with conical intersections. The study uses high-resolution velocity map ion imaging technique to observe rapid oscillations of H2 products, which can only be reproduced by theoretical ca...

Study reveals how Chinese travellers use technology abroad

Chinese backpackers rely heavily on digital technologies like Ali Pay and WeChat Pay for mobile payments and enjoy sharing their travel experiences on social media to receive comments and complements. Their IT use is influenced by collectivistic culture, guanxi, and the need for constant connectedness with families.
