Certain 2-(1'-iminothioimido substituted)-1'-substituted phenybenzoic acids (P(1-9)) were synthesized by reaction of phthalic anhydride with benzotriazole, 2-mercapto benzothiazole and 2-p-amino phenyl benzimidazole, respectively (A(1-3)) followed by imine formation with Schiff bases of thiourea with salicylaldehyde, furfuraldehyde and 1-phenyl-3-methyl-5-pyrazolone. Antiulcer activity was eval...

The aim of this study was to identify various bacteria isolated from grapes and their wines. Additionally we investigated the capacity of lactic acid bacteria for microbiological deacidification of wines produced in Poland. We have identified Oenococcus oeni, Lactobacillus acidophilus and Lactobacillus delbrueckii. During the microbial deacidification process, we observed decreases of total aci...

The ability of the lungs to clear deposited material is essential for maintenance of lung homeostasis. Acid aerosols have been shown to alter the efficiency of this process. This paper assesses the role of acid aerosol exposure concentration (C), exposure time (T), and relative acidity in producing changes in clearance from both the tracheobronchial tree and respiratory region of the lungs of r...

1. In six volunteers, the effect of intragastric administration of different water-soluble chemical isolates of dietary fibre on gastric secretion, acidity and emptying was studied. 2. At 30 min after administration of the test meals, the stomach contents were completely aspirated and the volume, pH, phenol red concentration, total titratable acidity and different electrolytes were measured. 3....

in present research the effects of four levels (0, 0.5, 1, 2 mm) of each of salicylic acid and putrescine treatments on the quality improvement of granny smith apple fruit were studied. factorial experiment in randomized complete block with three replications on 16 trees, eighteen years in researcher station of agriculture university of tehran was designed. for this purpose the trees were spray...

Doogh is an Iranian traditional dairy-based drink product formally identified as Iranian national drink. This fermented acidified drink has high nutritional value and pleasant organoleptic properties. Samples (n= 120) collected from both industrial and traditional Doogh retail stores in Hamadan in 2015 were analyzed for total solids (%), pH, titratable acidity, salt (%), mold and yeasts count (...

Circadian rhythms are driven by endogenous clock gene and affects in several gastric parameters causing ulcerogenesis. The study was aimed to evaluate the time dependent antiulcer activity of hydroxyzine in cold-stress-induced ulcer model. The ulcer protection effect of hydroxyzine was studied at various time intervals (9 am, 1 pm, 5 pm, 91 pm, 1 am and 5 am) in cold stress ulcer model using wi...

In recent years, climate change has strongly influenced viticulture, with a higher concentration of sugars in grapes, lower organic acids and, therefore, increases alcohol and pH. This work aimed to increase the total acidity Cava base wine different commercial strains: Saccharomyces cerevisiae (IO), hybrid S. x uvarum (VE) Lachancea thermotolerans (LA). Several laboratory industrial fermentati...
