Protein kinase C (PKC) is an important constituent of the signaling pathways involved in apoptosis. The PKC inhibitor staurosporine induces apoptosis in many cell types. We characterized the role of PKC in the induction of apoptosis in immature rat thymocytes by investigating the effects of staurosporine with those of five analogs. Four of them, the indolocarbazoles CGP 41251 and UCN-01 and the...

Gerbera is one of the most popular cut flowers in the world. Several experiments have been done on the effect of different chemical compounds on longevity and quality of cut flowers. In the present study, two experiments based on a completely random design with two treatments and three replications were conducted on gerbera cut flower cv. Sorbet. The first experiment examined the effect of BA, ...

Twenty wether lambs were individually fed for 84 days to study the effect of dietary lead on performance and mineral composit ion of selected tissues. The treatments included O, 10, 100, 500 and 1,000 ppm supplemental lead as lead acetate added to a practical diet. Increased dietary lead did not affect feed consumption, weight gain or feed conversion ratio. Hemoglobin, hematocri t and blood lea...

Two experiments were conducted to evaluate relationships among luteinizing hormone (LH), estradiol-17 beta (E2) and progesterone secretion during the preovulatory period in the heifer after prostaglandin F2 alpha (PGF2 alpha)-induced regression of the corpus luteum. A second objective was to elucidate the effects of E2 in regulating LH secretion. In Exp. 1, LH, E2 and progesterone concentration...

in this study, the effect of retentate and whey protein concentrate in different concentrations on the properties of low fat synbiotic yoghurt was studied. retentate samples containing different concentrations of the three concentrations ( 0.5 , 0.75 and 1 %) and whey protein concentrate ( 0.2 , 0.3 and 0.4 %) were prepared and characterized in terms of physicochemical , rheological and sensory...
