We aimed in this study to determine the cardiac reserve in preterm infants with phonocardiogram. One hundred and fifty-four preterm infants participated in this study. The ratio of the first heart sound to the second heart sound (S1/S2), the ratio of diastolic to systolic duration (D/S) and the cardiac contractility change trend after stimulation (CCCTS) were measured in all infants. The preter...

Weight specific oxygen consumption and heart rates were investigated in blue swimming crab, Portunus pelagicus to indicate the stress in response to increasing salinities (50, 75, 100 and 125%SW) and increasing copper concentration (0, 0.75, 1.5, 3 and 6 ppm copper) at temperature 25 degrees C. Oxygen consumption (micromol.g(-1).h(-1) was measured using closed system respirometer (Strathkelvin ...

The present study investigated the effects of the nutritional levels of diets on meat quality and related gene expression in Hainan black goat. Twenty-four goats were divided into six dietary treatments and were fed a concentrate-based diet with two levels of crude protein (CP) (15% or 17%) and three levels of digestive energy (DE) (11.72, 12.55 or 13.39 MJ/kg DM) for 90 days. Goats fed the con...

this experiment was performed in order to determine effects of different levels of dietary l-threonine supplementation in male japanese quails’ diets on immune response, small intestinal morphology, blood parameters and microflora.one hundred and forty four, 1-d old japanese quails have been selected and randomly distributed between six treatments and four replicates. basal ration was based on ...

the demand for low fat snacks is increasing. there are different methods to produce low fat fried products. one of these methods is coating. in this study effect of carrageenan, oil temperature and frying time, on oil uptake of fried products (chips and strips) has been evaluated. samples were deep fried in frying oil (palm olein) at 160, 175 and 190 ºc. in order to evaluate the effect of fryin...

For designing a complex vector that has the advantages of both polyethylenimine (PEI) and chitosan for gene delivery, a PEI/chitosan/DNA complex was constructed at various N/P ratios (the ratios of moles of the amine groups of cationic polymers to those of the phosphate ones of DNA) and both the cytotoxicity and the transfection efficiency of the vector were evaluated. The results demonstrated ...
