this study was conducted to evaluate the effects of beta plus probiotic, a mixture of bacillius leicheniformic and bacillius subtilis , on the growth performance and intestinal microbial flora of caspian trout ( salmo caspius ). a basal diet was formulated and supplemented with beta plus at 0, 0.5 and 1 g kg -1 , leading to three experimental diets. each experimental diet was randomly assigned ...

the cotton bollworm, helicoverpa armigera (hübner), is one of the important polyphagous pests causing serious loss to many economically important crops in iran. the goal of this experiment was to study the age-stage, two-sex life table of h. armigera on different bean cultivars including white kidney bean (cultivars daneshkadeh, pak, and shokufa), red kidney bean (cultivars akhtar, naz, and say...

sequence for bovine growth hormone, though there are several differences from that given by the other groups. We have studied the amino acid sequence of ovine growth hormone (Davies, 1974); this has also been investigated by other groups (Fernhndez et al., 1972; Li et al., 1972). The sequence is very similar to that of the bovine hormone, differing only at one or two amino acid residues. We hav...

To investigate effects of high-fat diet (HFD) on body length, weight and depression-like behavior prenatal stress (PS) offspring rats. PS rat model was established by restraint stress. Sucrose preference forced swimming tests were performed. Moreover, the HFD growth in rats observed. Length male female HF group significantly longer than that control, but length PS+HF shorter group. Body higher ...

Rapid depletion of iron from the growth medium induces the synthesis of two membrane proteins with a subunit molecular weight of 160,000 (160K) and 130,000 (130K) in cultured normal rat kidney cells. When iron is maintained at normal levels in the growth medium of normal rat kidney cells, the synthesis of the 160K and 130K proteins is suppressed. We found that 160K and 130K are the underglycosy...

The relationship between ribonucleotide reductase and tumor growth rate was measured in a series of rat hepatomas of different growth rates. An excellent correlation was found between tumor growth rate and the specific activity of ribonucleotide reductase. Differences of ZOO-fold in enzyme specific activities exist between the very fast and the slow growing hepatomas. This represents the larges...

In attempts to design a complete purified diet some observations were made on the rates of weight increase in rats receiving simple basal diets with various supplements. A recent review by Dunn, Murphy & Rockland (1947) on the optimal growth rate of the rat increased our interest in the studies of Zucker, Hall, Young & Zucker (1941 a-c) on the relation of weight to age in the rat and, although ...

The proliferative response of nontransformed rat embryo (Rat-1) cells and avian sarcoma virus-transformed B31 cells to high-density lipoprotein (HDL), transferrin, insulin, epidermal growth factor (EGF), and fibroblast growth factor has been compared. HDL, added in combination with transferrin, supported the active proliferation of low-density cultures of both Rat-1 and B31 cells. No major diff...
