Changes in chemical composition and the activities of hydrolytic enzymes during four different stages of maturity, viz. mature green (MG), color turning (CT), ripe (R), and overripe (OR), have been studied in guava fruits cv. Banarsi Surkha. Chlorophyll content decreased while carotenoid content increased during ripening. Starch content decreased with(More)
Production performance and egg quality were compared between 4 strains of beak-trimmed layers: 3 commercial strains-Lohmann White (LW), H&N White (HN), Lohmann Brown (LB)-and a noncommercial cross between Rhode Island Red (male) and Barred Plymouth Rock (female) in conventional cages and in floor pens. All chicks were reared and 857 pullets were housed at(More)
Softening is a developmentally programmed ripening process, associated with biochemical changes in cell wall fractions involving hydrolytic processes resulting in breakdown of cell-wall polymers such as cellulose, hemicelluloses and pectin etc. Various hydrolytic reactions are brought about by polygalacturonase, pectin methyl esterase, pectate lyase,(More)
BACKGROUND Gastrointestinal (GI) and non-GI disorders are associated with altered intestinal permeability, which can be measured in vivo by urinary excretion after oral lactulose and mannitol ingestion. Inadvertent dietary consumption of (12) Carbon ((12) C, regular) mannitol in food or from other sources may interfere with the test's interpretation. (13)(More)
Pathogenic yeasts from the genus Candida can cause serious infection in humans particularly, in immunocompromised patients and are now recognized as major agents of hospital acquired (nosocomial) infections. In the recent years, there has been a marked increase in the incidence of treatment failures in candidiasis patients receiving long-term antifungal(More)
Our aim was to understand the information from differential two-sugar excretion (2-SE) in measuring intestinal permeability. In a crossover study in 12 healthy volunteers, we compared urinary excretion ratios of lactulose (L) to mannitol [(M) LMR] after ingestion in liquid formulation (LF) or in delayed-release, methacrylate-coated capsules (CAP). Both(More)
A three-strain mixture of Escherichia coli O157:H7 was inoculated into fresh dairy compost (ca. 10(7) CFU/g) with 40 or 50% moisture and was placed in an environmental chamber (ca. 70% humidity) that was programmed to ramp from room temperature to selected composting temperatures in 2 and 5 days to simulate the early composting phase. The surviving E. coli(More)
Thermal resistance of heat-shocked Escherichia coli O157:H7, Salmonella, and Listeria monocytogenes was compared with that of non-heat-shocked (control) strains in finished dairy compost. A three-strain mixture of each pathogen was heat shocked at 47.5°C for 1 h and inoculated into the compost at a final concentration of 10(7) CFU/g. The inoculated compost(More)
Bile acid malabsorption (BAM) is reported in up to 50% of patients with functional diarrhoea and irritable bowel syndrome with diarrhoea (IBS-D). Serum 7alpha-hydroxy-4-cholesten-3-one (7alphaHCO or 7alphaC4), an indirect measurement of hepatic bile acid synthesis, has been validated as a measurement of BAM relative to the (75)SeHCAT retention test. Our aim(More)
Measurements of the heterophil:lymphocyte (H/L) ratio (invasive technique) and corticosterone in yolk and albumen (noninvasive techniques) were used to measure stress in 3 commercial laying strains, Lohmann White (LW), H&N White (HN), Lohmann Brown (LB), and a noncommercial cross (CR) between Rhode Island Red (male) and Barred Plymouth Rock (female), kept(More)
