Haematology and biochemical parameters of different feeding behaviour of teleost fishes from Vellar estuary, India

Abstract: Haematological parameters have been recognized as valuable tools for monitoring fish health. Haematological and serum biochemical parameters were studied and compared different feeding behaviour of teleost fishes. Three marine teleost fishes, Lates calcarifer (carnivores), Mugil cephalus (omnivores) and Chanos chanos (herbivores), were carried out in order to find out a normal range of blood parameters which would serve as baseline data for assessment of the health status of the fish as well as reference point for future comparative surveys. Blood parameters such as red blood cell count (RBC) and white blood cells count (WBC), haemoglobin, haematocrit, mean cell haemoglobin concentration (MCHC), mean cell volume (MCV), mean cell haemoglobin, glucose, protein, cholesterol and urea were estimated from teleost fishes of different trophic level. Statistical analysis revealed that differences in haematological parameters between marine fish were significant (P < 0.01). The result revealed that haematological RBC/WBC ratio, MCV and MCHC were significantly correlated at P < 0.05 level. The RBC/WBC level increased due to the decrease in WBC during the study. Blood serum biochemical parameters can be used for confirming the maturity and monitoring any changes in the quality of waters and related soils.

Evaluation of overall line effectiveness (OLE) in a continuous product line manufacturing system

Abstract: Purpose – The total productive maintenance concept provided a quantitative metric – overall equipment effectiveness (OEE), for measuring the effectiveness of individual equipment in a factory, which is significant but insufficient since world class manufacturing (WCM) system focus on product line involving machines in series. This paper aims to present an approach to measure the overall line effectiveness (OLE) in continuous line‐manufacturing system.Design/methodology/approach – Systematic methodology, based on OEE metrics, is developed to model the productivity of a line manufacturing system in terms of OLE. The general and step‐by‐step method of OLE measurement in the line consisting of n number of processes is explained using a flow chart.Findings – Computer simulation has been carried out for the evaluation of OLE in product line manufacturing system with n number of machines. It also identifies the bottle‐neck machines and the effect of specific contributing parameter for improvement.Practical impli...

Taurine restores ethanol-induced depletion of antioxidants and attenuates oxidative stress in rat tissues.

Abstract: Ethanol by its property of generating free radicals during the course of its metabolism causes damage to cell structure and function. The study investigates the protective effects of the antioxidant aminoacid taurine on ethanol-induced lipid peroxidation and antioxidant status. Male Wistar rats of body weight 170–190 g were divided into 4 groups and maintained for 28 days as follows: a control group and taurine-supplemented control group, taurine supplemented and unsupplemented ethanol-fed group. Ethanol was administered to rats at a dosage of 3 g/kg body weight twice daily and taurine was provided in the diet (10 g/kg diet). Lipid peroxidation products and antioxidant potential were quantitated in plasma and in following tissues liver, brain, kidney and heart.
