High Rates of Obesity and Chronic Disease Among United Methodist Clergy

We used self‐reported data from United Methodist clergy to assess the prevalence of obesity and having ever been told certain chronic disease diagnoses. Of all actively serving United Methodist clergy in North Carolina (NC) 95% (n = 1726) completed self‐report height and weight items and diagnosis questions from the Behavioral Risk Factor Surveillance Survey (BRFSS). We calculated BMI categories and diagnosis prevalence rates for the clergy and compared them to the NC population using BRFSS data. The obesity rate among clergy aged 35–64 years was 39.7%, 10.3% (95% CI = 8.5%, 12.1%) higher than their NC counterparts. Clergy also reported significantly higher rates of having ever been given diagnoses of diabetes, arthritis, high blood pressure, angina, and asthma compared to their NC peers. Health interventions that address obesity and chronic disease among clergy are urgently needed.     

Isoleucine and Valine Metabolism in Escherichia coli XVIII. Induction of Acetohydroxy Acid Isomeroreductase

The regulation by substrate induction of the acetohydroxy acid isomeroreductase was studied in Escherichia coli. Induction was inhibited by chloramphenicol and rifampin. The addition of rifampin resulted in a decay of the capacity to form isomeroreductase. This was attributed to the breakdown of the isomeroreductase messenger, which had a half-life of about 45 sec at 37 C. Induction of isomeroreductase was enhanced by including glucose in the medium. This effect was shown to be due in part to the lowering of the pH of the medium, which presumably made inducer entry more rapid.     

Morphogenesis of the dorsal pigmentary pattern in wild-type and mutant Rana pipiens

The transition from larval to adult pigmentary patterns during metamorphosis of wild-type. burnsi, and kandiyohi R. pipiens is described. Larval fusiform epidermal melanocytes form a pattern that exactly corresponds to the adult spotting pattern. It is concluded that the larval epidermal pattern expresses a “prepattern” in the larval tissue for the adult pattern. This “prepattern” is visible in kandiyohi, but not in burnsi, tadpoles. The role of the extracellular environment in pigmentary pattern determination is discussed. Gradual changes in all chromatophore densities accompany larval development, while abrupt changes accompany metamorphic climax. There is a net increase in all chromatophore densities by the completion of metamorphosis. Kandiyohi density changes differ quantitatively but not qualitatively from those of wild type. In both wild type and kandiyohi, differentiation of many new dermal melanophores in presumptive spot regions effects expression of the adult spotting pattern. The relative roles of chromatophore differentiation and mitosis in pattern expression, and the hormonal control thereof, are discussed.
