Cinnamon and vinegar or acetic acid were reported to reduce the postprandial blood glucose response. We hypothesized that the combination of these substances might result in an additive effect. Therefore, we determined the 2-hour postprandial blood glucose and satiety response to a milk rice meal supplemented with either cinnamon or acetic acid on their own or in combination. Subjects (n = 27) ...

A convenient and practical synthesis of imidazol-1-yl-acetic acid hydrochloride was achieved via N-alkylation of imidazole using tert-butyl chloroacetate followed by a non-aqueous ester cleavage of the resulting imidazol-1-yl-acetic acid tert-butyl ester in the presence of titanium tetrachloride. The synthesized imidazol-1-yl-acetic acid hydrochloride was then utilized to prepare zoledronic acid.

INTRODUCTION Acrylic resins containing acrylic acid (AA), methyl methacrylate (MMA) or acrylic–methacrylic copolymer are the most commonly used polymeric materials for biomedical and pharmaceutical applications owing to their hydrophilicity and biocompatibility.1–4 Recently, a new polyvinyl alcohol (PVA) copolymer designed by copolymerizing AA and MMA with PVA was successfully developed as a ca...

In this study, fluconazole (FLZ) loaded poly (lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) were prepared with two different formulations consisting of polyvinyl alcohol (PVA) and PVA-rhamnolipid (R) in order to improve antibiofilm activity against Candida albicans ATCC 90028. The encapsulation efficiency, drug loading capacity, in-vitro release, characterization these compared. Character...

In this work evidence is presented that acid stress adaptation protects Saccharomyces cerevisiae from acetic acid-mediated programmed cell death. Exponential-phase yeast cells, non-adapted or adapted to acid stress by 30 min incubation in rich medium set at pH 3.0 with HCl, have been exposed to increasing concentrations of acetic acid and time course changes of cell viability have been assessed...

Integrally-skinned asymmetric Polyetherimide/Poly (vinyl alcohol) (PEI/PVA) hollow fber membranes for pervaporation dehydration were fabricated by non-solvent induced phase inversion. PVA inside the PEI matrix could be crosslinked to provide membrane performance stability during long term operation. The effects of different PEI/PVA blend ratio, external coagulant type and...

To investigate the efficacy of the intake of vinegar for prevention of hyperlipidaemia, we examined the effect of dietary acetic acid, the main component of vinegar, on serum lipid values in rats fed a diet containing 1 % (w/w) cholesterol. Animals were allowed free access to a diet containing no cholesterol, a diet containing 1 % cholesterol without acetic acid, or a diet containing 1 % choles...

Acetic acid-soluble and insoluble proteins were isolated from doughs mixed in the presence of N-ethylmaleimide (NEMI). Reducedpyridylethylated acetic acid-insoluble protein (AF) and reducedpyridylethylated acetic acid-soluble protein (BF) were sequentially fractionated into an acetic acid-insoluble fraction (F-0), an acidic 70% ethanol-insoluble fraction (F-I), a neutral 70% ethanol-insoluble f...

Acidic chitinase (Chia) has been implicated in asthma, allergic inflammations, and food processing. We have purified Chia enzymes with striking acid stability and protease resistance from chicken and pig stomach tissues using a chitin column and 8 M urea (urea-Chia). Here, we report that acetic acid is a suitable agent for native Chia purification from the stomach tissues using a chitin column ...

Background: Caustic substance ingestion is known for causing a wide array of gastrointestinal and systemic complications. In Russia, ingestion of acetic acid is a major problem which annually affects 11.2 per 100,000 individuals. The objective of this study was to report and analyze main complications and outcomes of patients with 70% concentrated acetic acid poisoning. Methods: This was a retr...
