Early-life hypoxia alters adult physiology and reduces stress resistance and lifespan in .

In many animals, short-term fluctuations in environmental conditions in early life often exert long-term effects on adult physiology. In , one ecologically relevant environmental variable is hypoxia. larvae live on rotting, fermenting food rich in microorganisms, an environment characterized by low ambient oxygen.

Factors affecting bowel preparation adequacy and procedural time.

Background And Aim: Poor bowel preparation results in difficult colonoscopies, missed lesions, and repeat procedures. Identifying patient risk factors for poor bowel preparation, such as prolonged runway time and prolonged cecal intubation, will aid in interventions prior to a procedure.

Methods: This was a retrospective, single-center analysis of 3 295 colonoscopies performed between May 2012 and November 2014.

Additive Effect on Soybean Peroxidase-Catalyzed Removal of Anilines from Water.

Soybean peroxidase has been shown to be effective in removal of aromatic compounds from wastewater, while the use of additives effectively reduces enzyme concentration requirement, hence overall treatment cost. Enzymatic treatment, an oxidative polymerization, was successful in removal of over 95% of both aniline and -anisidine. The originality of this study lies in the findings that the additives, sodium dodecyl sulfate (SDS), sodium dodecylbenzenesulfonate (SDBS), Triton X-100, and sodium dodecanoate (SDOD), reduced enzyme concentration requirement, while polyethylene glycol (PEG, average molar mass of 3350 g/mol) had no effect on the required enzyme concentration.

Use of pethidine for percutaneous liver biopsy - a randomised, placebo-controlled, double blind study.

Background: Percutaneous liver biopsy (PLB) is the "gold standard" in the diagnosis of liver diseases. A pilot trial has shown pethidine may reduce anxiety and the need for post-procedural pain relief. The aim of this study was to investigate the role of pre-procedural pethidine.
