The objective of this randomized, single-blind crossover study was to examine the effect of vinegar on the blood glucose response to meal ingestion. This study was associated with a companion study Is Apple Cider Vinegar Effective for Reducing Heartburn Symptoms Related to Gastroesophageal Reflux Disease. Glucose meters were utilized to measure blood glucose levels immediately prior to, and at four ½ hour intervals following meal ingestion. Previous studies have demonstrated that vinegar modulates the meal-time glucose response. Hence an alternative hypothesis was used: that a significant difference will be observed between the control and the vinegar groups. The results from the study were not significant likely due to a small sample size. The test meal eaten with a drink composed of vinegar diluted in water appeared to be most effective at decreasing the overall change in postprandial blood glucose. The vinegar drink also played a role in decreasing the peak glucose level at 30 minutes post-meal.

Characterization of a Polyclonal Antibody Specific for Synechococcus WH8102 Plastoquinol Terminal Oxidase.

Description
Photosynthesis is a critical process that fixes the carbon utilized in cellular respiration. In higher plants, the immutans gene codes for a protein that is both involved in carotenoid biosynthesis and plastoquinol oxidation (Carol et al 1999, Josse et al 2003). This plastoquinol terminal oxidase (PTOX) is of great interest…

Photosynthesis is a critical process that fixes the carbon utilized in cellular respiration. In higher plants, the immutans gene codes for a protein that is both involved in carotenoid biosynthesis and plastoquinol oxidation (Carol et al 1999, Josse et al 2003). This plastoquinol terminal oxidase (PTOX) is of great interest in understanding electron flow in the plastoquinol pool. In order to characterize this PTOX, polyclonal antibodies were developed. Expression of Synechococcus WH8102 PTOX in E. coli provided a useful means to harvest the protein required for antibody production. Once developed, the antibody was tested for limit of concentration, effectiveness in whole cell lysate, and overall specificity. The antibody raised against PTOX was able to detect as low as 10 pg of PTOX in SDS-PAGE, and could detect PTOX extracted from lysed Synechococcus WH8102. The production of this antibody could determine the localization of the PTOX in Synechococcus.
