The objective of the current study was to determine seasonal changes in glucose, cholesterol, non-esterified fatty acids (NEFA), serum inorganic phosphorous (SIP), calcium, magnesium and iron concentrations in Nguni and crossbred cattle on the sweet and sour rangelands of the Eastern Cape Province of South Africa. Body weights, body condition scores (BCS) and serum concentrations of energy-rela...

The relationship between taste receptor cell (TRC) Ca(2+) concentration ([Ca(2+)](i)) and rat chorda tympani (CT) nerve responses to salty [NaCl and NaCl+benzamil (Bz)] and sour (HCl, CO(2), and acetic acid) taste stimuli was investigated before and after lingual application of ionomycin+Ca(2+), 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid acetoxymethyl ester (BAPTA-AM), U73122 (pho...

In the present work the effects on dough quality by the down-regulation of γ-gliadins in different genetic backgrounds of bread wheat were investigated. RNAi-mediated silencing of γ-gliadins was introgressed by conventional crossing into three commercial bread wheat lines (namely 'Gazul', 'Podenco' and 'Arpain'), and along with the transgenic line A1152 (cv. Bobwhite) compared with their respec...

In the past, the fermentation activity of Saccharomyces cerevisiae in substrates with a high concentration of sucrose (HSuc), such as sweet bread doughs, has been linked inversely to invertase activity of yeast strains. The present work defines the limits of the relationship between invertase activity and fermentation in hyperosmotic HSuc medium. Fourteen polyploid, wild-type strains of S. cere...

OBJECTIVE: Oxidative stress is a serious complication in diabetic patients. Black tea and also sour tea contained some flavonoids with antioxidant properties and may be helpful in prevention of lipid oxidation. The aim of this study was to compare the effects of sour tea and black tea on in-vitro copper induced serum lipids oxidizability in diabetic patients. MATERIALS AND METHODS: In this se...

Background and objective: Peel oil and juice of citrus fruits have furocoumarin (Psoralen) that can induce phytophotodermatitis. If the reaction is mild, then only hyperpigmentation (Without itching, burning, erythema, vesicle and bullae, formation) may occur. The objective of this study was to describe the patients with hyperpigmentation of back of the hands. Materials and Methods: Thirty-two ...

The goal of this study was to determine the impact of physiological growth states (batch exponential and batch stationary growth) and growth modes (substrate-limited chemostat, substrate-sufficient exponential batch, and substrate-depleted stationary batch growth) on several measures of growth and responses to Cd(II)-mediated inhibition of Nitrosomonas europaea strain 19718. The specific oxygen...

BACKGROUND Delirium is a common condition in hospitalized seniors that nonetheless often goes undetected by nurses or is delayed in being detected which negatively impacts quality of care and outcomes. We sought to develop a new screening tool for delirium, The Sour Seven Questionnaire, a 7-item questionnaire suitable to be completed from informal or untrained caregiver observation. The study a...

Objectives: The study investigated the functioning of the taste and smell senses in workers employed at a sewage treatment plant and waste landfill. Materials and Methods: The study population was divided into three groups: sewage workers (group 1), landfill workers (group 2), and laboratory workers (group 3). Smell sensation was assessed using the Börstein gustometry method and taste sensation...
