The Effect of Obesity on the Quality of Bowel Preparation for Colonoscopy: Results From a Large Observational Study.

Background: Obesity has been linked to suboptimal bowel preparation but this association has not been conclusively investigated in prospective studies.

Goals: Our objective was to determine whether any relationship exists between obesity as measured by body mass index (BMI) and quality of bowel preparation.

Study: Adult patients who presented for outpatient colonoscopy at a single urban ambulatory surgery center within a 6-month period and fulfilled inclusion criteria were prospectively enrolled for the study.

Water Soluble Phosphane-Gold(I) Complexes. Applications as Recyclable Catalysts in a Three-component Coupling Reaction and as Antimicrobial and Anticancer Agents.

Water-soluble compounds of the type [AuCl(PR)] with alkyl-bis-(-sulfonated-phenyl)-(CHSONa) and dialkyl-(-sulfonated-phenyl)-(CHSONa) (R = Bu, Cp) phosphanes have been prepared. Dialkyl-phosphane compounds generate water-soluble nanoparticles of 10-15 nm radius when dissolved in water. These air-stable complexes have been evaluated as catalysts in the synthesis of propargylamines via a three-component coupling reaction of aldehydes, amines and alkynes in water.
