The effects of dietary lipid and carbohydrate, and their interaction, on growth performance and body composition of juvenileblunt snout bream Megalobrama amblycephala were investigated. Fish were fed one of eight isonitrogenous (32% crude protein) diets containing 4% or 7% lipids and 25%, 30%, 35%, or 40% carbohydrate for nine weeks. Weight gain, feed conversion ratio, protein efficiency ratio,...

background: phthalates are a group of multifunctional chemicals. diethyl phthalate (dep) is one of the most frequently used phthalates in solvents and fixatives for numerous industrial products. method: the present experiment was designed to assess oxidative stress, if any, caused by diethyl phthalate. for this the homogenates of liver and kidney were treated with different concentrations ( 10-...

A series of two experiments was conducted to study the optimum dietary protein level and protein to energy ratio of lemon fin barb hybrid larvae. In Experiment 1, five isocaloric diets (4700 kcal per kg) ranging from 40 to 60% protein in 5% increments were fed to triplicate groups of lemon fin barb hybrid larvae (initial weight: 0.10 ± 0.01 mg per fish) for 21 days. Weight gain of fish was prop...

objective(s): ex vivo expansion of hematopoitic stem cells is an alternative way to increase umbilical cord blood (ucb)-cd34+ cells for bone marrow transplantation. for this purpose demineralized bone matrix (dbm) and mineralized bone allograft (mba) as two scaffolds based on bone matrix and stem cell niche, were simultaneously used to enhance the effect of human mesenchymal progenitor cells (m...

To study how the metabolism of N-nitrosodimethylamine (NDMA) is affected by dietary protein level and chronic ethanol feeding, 24 rabbits at 18 weeks of age, assigned to four groups, each with 6 rabbits, were fed for 8 weeks on the following 4 different diets; 21% protein content containing 21.1% casein and water, 21% protein content containing 21.1% casein and 7.5% ethanol, 7% protein content ...

We studied sea-level residents during 13 days of altitude acclimatization to determine 1) altitude acclimatization effects on erythrocyte volume and plasma volume, 2) if exogenous erythrocyte volume expansion alters subsequent erythrocyte volume and plasma volume adaptations, 3) if an increased blood oxygen content alters erythropoietin responses during altitude acclimatization, and 4) mechanis...

BACKGROUND The tremendous supply and low cost of distillers dried grains with solubles (DDGS) make it an attractive feedstuff for aquaculture diets. Also, several studies have shown that DDGS can be successfully fed to various finfish. The objective of this study was to evaluate the effects of inclusion rate of DDGS (0, 250, 500 g kg(-1) ), feed moisture content (350, 450 g kg(-1) ) and die ope...

A central composite rotatable design with four independent variables viz. blend ratio (broken rice flour and cowpea flour): 90:10–70:30, moisture content (10–18% wet basis), barrel temperature (110–150 °C), screw speed (280–360 rpm) were varied in the development of ready-to-eat snacks using a twin extruder for broken rice–cowpea product. The effects on specific mechanical energy, water absorpt...

formation of hydraulic jump is necessary for dissipation of the excess kinetic energy downstream of spillways and gates. hydraulic jump stilling basins of sudden expansion are one of the energy dissipater structures which are used where the available tail water depth is less than the required sequent depths. in the present study to further reduce the hydraulic jump sequent depths ratio, a rough...
