The effect of a meat load on the renal handling of acid-base balance was studied in ten healthy subjects (GFR by inulin clearance = 98.5 +/- 8.14 ml.min-1.1.73 m-2) and in ten patients affected by chronic renal failure (CRF) (GFR = 39.9 +/- 5.3 ml.min-1.1.73 m-2). After the meat load (2 g.kg-1 body weight of cooked unsalted red meat), GFR increased by 26.9% (peak value) over baseline in healthy...

‘Smyrna’ type figs (Zidi ‘ZD’: dark fruit and Thgagli ‘THG’; Bidhi ‘BD’ and Khedri ‘KHD’: white fruit) originated from two areas of fig production in Tunisia were subject to physico-chemical description and spectrophotometric analysis for their sugar (glucose, fructose and sucrose) and organic acid (citric and malic) contents. Fruit weight ranged between 54 and 82 g, fruit width between 47 and ...

in order to evaluate the effect of different concentrations of postharvest salicylic acid and calcium chloride on shelf life, quality characteristics and antioxidant activity of peach fruit cv. amesden, an experiment was conducted as factorial based on randomized completely design with three replications. fruits were harvested at the commercial ripening stage, and fruits were immerged in differ...

The objective of this study was to evaluate the quality strawberries distributed in global markets. We obtained from Egypt, Mexico, Republic Korea, Spain, and United States America (US) being sold Singapore, compared them with Japanese (cv. Benihoppe) using instrumental analysis sensory evaluation. Sensory evaluation conducted by Singaporean assessors. results showed that Egypt were relatively ...

pomegranate is one of the major horticultural crops in iran, but studies about this product; especially its pruning is very little. therefore this study was carried out to assess the effect of pruning and nutrition on pomegranate cultivar “robab” in qaemieh, fars province during 2008-2009. this research was conducted factorial experiment based on randomized complete block design (rcbd) with 5 p...

Correct protonation of titratable groups in biomolecules is crucial for their accurate description by molecular dynamics simulations. In the context of constant pH simulations, an additional protonation degree of freedom is introduced for each titratable site, allowing the protonation state to change dynamically with changing structure or electrostatics. Here, we extend previous approaches for ...

Relative to the gills, the mechanisms by which the kidney contributes to ammonia and acid-base homeostasis in fish are poorly understood. Goldfish were exposed to a low pH environment (pH 4.0, 48 h), which induced a characteristic metabolic acidosis and an increase in total plasma [ammonia] but reduced plasma ammonia partial pressure (PNH3). In the kidney tissue, total ammonia, lactate and intr...

BACKGROUND Ten genotypes representing two elderberry species, Sambucus canadensis L. (eight genotypes) and S. nigra L. (two genotypes), were examined for their anthocyanins (ACY), total phenolics (TP),°Brix, titratable acidity (TA), and pH over two growing seasons. RESULTS Overall, fruit generally had higher ACY, TP, ACY/TP,°Brix, and pH in 2005 than 2004. All samples of S. canadensis had sim...

The consumption of fresh-cut pomegranate fruits (arils) has risen recently due to their bioactive compounds and benefits for consumers. However, arils have a limited shelf-life vastly lose valuable compounds. Therefore, in this study, we investigated the effects exogenous postharvest treatment with salicylic acid (SA), methyl Jasmonate (MeJA), combination on chemical composition under refrigera...

These investigations originated in studying the basis of a method for microbiological assay of nicotinic acid (McIlwain & Stanley, 1948). The method was that in which acid produced from glucose by Lactobacillus arabinosus 17-5 is titrated with alkali after a period of incubation of about 3 days. The assay depends on the empirical observation that the quantity of titratable acid produced during ...
