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...

Background: Despite safety reports of the artificial sweetener aspartame, health-related concerns remain. Objective: We prospectively evaluated whether the consumption of aspartameand 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 identifie...

infancy and causes severe vision loss, especially at night. An estimated 2,000 Americans have the form of the disease they targeted, Bennett said. But other reports were not satisfied with a mere 2,000 potential beneficiaries. New hope is offered to “millions affected by eye diseases” said the Independent. This was “hundreds of thousands” in the Los Angeles Times. But the LA Times also highligh...

BACKGROUND During the bread-making process, industrial baker's yeast, mostly Saccharomyces cerevisiae, is exposed to baking-associated stresses, such as air-drying and freeze-thaw stress. These baking-associated stresses exert severe injury to yeast cells, mainly due to the generation of reactive oxygen species (ROS), leading to cell death and reduced fermentation ability. Thus, there is a grea...

BACKGROUND Xylanase can replace chemical additives to improve the volume and sensory properties of bread in the baking. Suitable baking xylanase with improved yield will promote the application of xylanase in baking industry. The xylanase XYNZG from the Plectosphaerella cucumerina has been previously characterized by heterologous expression in Pichia pastoris. However, P. pastoris is not a suit...

Staphylococcus aureus has two superoxide dismutases (SODs), encoded by the sodA and sodM genes, which inactivate harmful superoxide radicals () encountered during host infection or generated from aerobic metabolism. The transcriptional start sites have been mapped and expression analysis on reporter fusions in both genes has been carried out. Under standard growth conditions, manganese (Mn), a ...

BACKGROUND Consumption of sugar-sweetened beverages, such as soda, have been shown to play an important role in weight gain. Although soda consumption has been associated with body mass index (BMI) in many studies, it has been difficult to ascertain a true causal relationship between soda consumption and BMI for two reasons. First, findings have been based largely on observational and cross-sec...

Measurement of soil CO2 efflux using a non-flow-through steady-state (NFT-SS) chamber with alkali absorption of CO2 by soda lime was tested and compared with a flow-through non-steady-state (FT-NSS) IRGAmethod to assess suitability of using soda lime for field monitoring over large spatial scales and integrated over a day. Potential errors and artifacts associated with the soda lime chamber met...

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 ...
