The genetic loci leading to anaerobic derepression of a sodA : : lac2 protein fusion in a UV-generated mutant strain (UV14) of Escherichia coli were identified. The mutant (UV14) was found to harbour two altered loci: one is in the trans-regulatory genefnv (fumarate nitrate reduction) where leucine-129 was changed to glutamine (finrl4), and the second (sodAl4) is in the promoter region (cis) of...

BACKGROUND Despite safety reports of the artificial sweetener aspartame, health-related concerns remain. OBJECTIVE We prospectively evaluated whether the consumption of aspartame- and sugar-containing soda is associated with risk of hematopoetic cancers. DESIGN We repeatedly assessed diet in the Nurses' Health Study (NHS) and Health Professionals Follow-Up Study (HPFS). Over 22 y, we identi...

The identification of Pasteurella and related bacteria remains a challenge. Here, a 449- to 473-bp fragment (sodA(int)) internal to the sodA gene, encoding the manganese-dependent superoxide dismutase, was amplified and sequenced with a single pair of degenerate primers from the type strains of Pasteurella (18 strains), Gallibacterium (1 strain), and Mannheimia (5 strains) species. The sodA(int...

Globally, soda taxes are gaining momentum as powerful interventions to discourage sugar consumption and thereby reduce the growing burden of obesity and non-communicable diseases (NCDs). Evidence from early adopters including Mexico and Berkeley, California, confirms that soda taxes can disincentivize consumption through price increases and raise revenue to support government programs. The Unit...

The increasing presence of nanomaterial and nanoproducts makes it imperative to learn more about the associated impacts of these materials on human health and the environment. In this study, the effect of the nanomaterial TiO2 on the phyllosphere microbial community was investigated. Analysis results by PCR-denaturing gradient gel electrophoresis revealed a TiO2-induced change in the community ...

Drinking too much of the bubbly? It?s not clear if you?re a regular or diet soda drinker, but regular soda is a source of sugar, caffeine, sometimes coloring, and little else. One twelveounce can of regular soda typically contains eight teaspoons of sugar and 130 calories ? but zero nutritional content. The American Heart Association [2] recommends that individuals assigned male at birth limit ...

Abstract The at meant of waste water from hexavalent chromium ions with calcium per oxide CaO 2 was investigated. This product is obtained soda ash production waste. Clarified part still suspension (distillation suspension) contains chloride and sodium chloride. process producing peroxide based on the interaction solutions hydroxide. A two-step (reagent) method purification proposed. first stag...

BACKGROUND Superoxide dismutases (SODs) cause dismutation of superoxide radicals to hydrogen peroxide and oxygen. Besides protecting the cells against oxidative damage by endogenously generated oxygen radicals, SODs play an important role in intraphagocytic survival of pathogenic bacteria. The complete genome sequences of Yersinia enterocolitica strains show presence of three different sod gene...
