Unlike the digestive systems of vertebrate animals, the lumen of the alimentary canal of Caenorhabditis elegans is unsegmented and weakly acidic (pH ~4.4), with ultradian fluctuations to pH > 6 every 45-50 s. To probe the dynamics of this acidity, we synthesized novel acid-activated fluorophores termed Kansas Reds. These dicationic derivatives of rhodamine B become concentrated in the lumen of ...

this study was carried out to investigate impacts of myrobalan rootstock and blackthorn interstem on fruit growth, physico-chemical features and bioactive compounds of two apricot cultivars (‘harcot’ and ‘roksana’) in 2010 and 2011. fruits of both cultivars on myrobalan and/or blackthorn grew with a classic double sigmoid curve from full bloom time to harvest. during growth and development peri...

ABSTRACT: The study aimed to analyze the physicochemical properties and starter culture viability of frozen yogurts produced with liquid cheese whey (LCW) inulin at different proportions (F0: 66% LCW 0% inulin; F1: 65% 1% F2: 64% 2% F3: 62% 4% inulin). Results demonstrated that yogurt F3 presented higher total solids carbohydrates levels. contributed overrun increase (11.8-18.2%) but did not in...

Due to climate change, grapes are reaching continuously higher levels of technological maturity. However, this also leads lower acidity and pH values in musts wines. Higher would result risk potential regarding undesirable microorganisms, associated with wine faults. Since 2013, cation exchangers have been allowed for acidification. In addition, yeasts the genus Lachancea releasing lactic acid ...

Apples (Malus domestica Borkh.) have been identified as one of the main dietary sources of antioxidants, mainly phenolic compounds. These compounds vary in their composition and concentration, among cultivars and fruit tissues. In this research, the total phenolic content (Folin-Ciocalteau assay), antioxidant capacity (Ferric Reducing Antioxidant Power, FRAP assay) and mineral composition in th...

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 (...

This study aimed to investigate the fermentation performance, sugar consumption, pH changes, total phenolic compounds, and antioxidant activity produced using different tea extracts concentrations kinetic characteristics of Kombucha fermentation. Three independent (10 g/L, 40 70 g/L) were used in process. The results showed that culture consumed all medium when concentration was below a certain...

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...

Yogurt-like products were prepared from a combination of skim milk and soymilk (100:0, 75:25, 50:50, 25:75, and 0:100) containing saccharified-rice solution by lactic fermentation of four different cultures. The ratio of skim milk and soy milk had no significant effect on titratable acidity, while the type and nature of culture used for fermentation affected the titratable acidity. Lower synere...
