SUMMARY Mutations in 1-acylglycerol-3-phosphate-O-acyltransferase 2 (AGPAT2) cause congenital generalized lipodystrophy. To understand the molecular mechanisms underlying the metabolic complications associated with AGPAT2 deficiency, Agpat2 null mice were generated. Agpat2−/− mice develop severe lipodystrophy affecting both white and brown adipose tissue, severe insulin resistance, diabetes, and hepatic steatosis. The expression of lipogenic genes and rates of de novo fatty acid biosynthesis were increased ~4-fold in Agpat2−/− mouse livers. The mRNA and protein levels of monoacylglycerol acyltransferase isoform 1 were markedly increased in the livers of Agpat2−/− mice suggesting that the alternative monoacylglycerol pathway for triglyceride biosynthesis is activated in the absence of AGPAT2. Feeding a fat-free diet reduced liver triglycerides by ~50% in Agpat2−/− mice. These observations suggest that both dietary fat and hepatic triglyceride biosynthesis via a novel monoacylglycerol pathway may contribute to hepatic steatosis in Agpat2−/− mice.

We examined the association between different types of prayer and depressive symptoms—with rumination and social support as potential mediators—in a sample of predominantly White, Christian, and female ambulatory cancer patients. In a cross-sectional design, 179 adult cancer outpatients completed measures of prayer, rumination, social support, depressive symptoms, and demographic variables. Type and stage of cancer were collected from electronic medical charts. Depressive symptoms were negatively correlated with adoration prayer (r = −.15), reception prayer (r = −.17), thanksgiving prayer (r = −.29), and prayer for the well-being of others (r = −.26). In the path analysis, rumination fully mediated the link between thanksgiving prayer and depressive symptoms (β for indirect effect = −.05), whereas social support partially mediated the link between prayer for others and depressive symptoms (β for indirect effect = −.05). These findings suggest that unique mechanisms may link different prayer types to lower depressive symptoms among cancer patients.

Understanding job satisfaction, stress, and burnout within agricultural education has the potential to impact the profession's future. Studying these factors through the theoretical lens of social comparison takes a cultural approach by investigating how agriculture teachers interact with and compare themselves to others. The purpose of this study was to determine if relationships existed between social comparison and job satisfaction and/or burnout among secondary agriculture teachers representing six states. Findings indicated that teachers were satisfied with their jobs and tended to engage most frequently in upward assimilative (UA) comparisons, leading to inspiration emotional outcomes. According to the Maslach Burnout Inventory for Educators (MBI-E), teachers experienced low levels of burnout related to personal accomplishment (PA) and depersonalization (DE), and moderate levels related to emotional exhaustion (EE). Seven moderate relationships were found between dimensions of social comparison and either burnout and/or job satisfaction.
