The Association of School Learning Environment With Adolescent Health Behaviors.

Background: In 2020, schools shifted to remote learning in response to mitigating COVID-19. Since then, students have fluctuated between in-person and remote learning environments. Changes to instructional models raise questions about the impact on health.

Enriched-GWAS and Transcriptome Analysis to Refine and Characterize a Major QTL for Anaerobic Germination Tolerance in Rice.

Tolerance of anaerobic germination (AG) is a key trait in the development of direct seeded rice. Through rapid and sustained coleoptile elongation, AG tolerance enables robust seedling establishment under flooded conditions. Previous attempts to fine map and characterize (), a major centromere-spanning AG tolerance QTL, derived from the indica variety Ma-Zhan Red, have failed.

Adolescent Health Behaviors in Schools with 4- Versus 5-Day School Weeks.

Background: The adoption of a shortened school week from the traditional 5 to 4 days is increasing nationwide. Budgetary and staffing needs are driving the change, yet research on the effects on students is lacking, especially regarding student health. Our study examined student health in 4 vs 5-day schools in Colorado, a state with one of the highest numbers of schools with a 4-day week.

Targeted Knockdown of GDCH in Rice Leads to a Photorespiratory-Deficient Phenotype Useful as a Building Block for C4 Rice.

The glycine decarboxylase complex (GDC) plays a critical role in the photorespiratory C2 cycle of C3 species by recovering carbon following the oxygenation reaction of ribulose-1,5-bisphosphate carboxylase/oxygenase. Loss of GDC from mesophyll cells (MCs) is considered a key early step in the evolution of C4 photosynthesis. To assess the impact of preferentially reducing GDC in rice MCs, we decreased the abundance of OsGDCH (Os10g37180) using an artificial microRNA (amiRNA) driven by a promoter that preferentially drives expression in MCs.

Treatment of myocardial infarction in a community hospital coronary care unit. Experience with 1,246 patients.

The hospital mortality in 1,246 consecutive acute myocardial infarction patients treated in a large community hospital coronary care unit was 14.4%. Of the total, 52.

Carbenicillin in the first nine months of unrestricted use. A chapter in the natural history of an antibiotic.

During the first nine months following its release for general use, carbenicillin was administered to forty-two patients in Hahnemann Hospital. Thirty-nine available records of patients receiving the drug for other than urinary infection were reviewed. Among children, all but one had mucoviscidosis: most were given acceptable therapeutic regimens; survival rate was 80%, and their physicians were favorably impressed.
