this experiment was conducted to examine the effect of multi-strain probiotic (primalac) on performance, immune responses and cecal microflora in broiler chickens under cyclic heat stress condition. a total of 96 one-d-old mixed sex broiler chicks (ross 308) were weighed and randomly allocated to two treatment groups, each with 4 replicate pens of 12 chicks. the dietary treatments were basal di...

electrode potential of 2-(2,3-dihydroxy phenyl)-1,3-dithiane (dpd) was investigated by means of cyclic voltammetry (cv) at various potential scan rates. the calculated value was compared with the experimental value obtained by cyclic voltammetry (cv). all experiments were done in aqueous phosphate buffer solutions at different phs. the experimental redox potential of dpd was obtained to be 0.75...

in this work, a novel electrochemical technique is presented for determination of bentazonusing a nanocomposite based sensor and continuous coulometric fast fourier transformation cyclicvoltammetry (ccfftcv). in this method, the sensor response is in coulomb and is calculated based onintegrating charge changes under the current voltammogram in selected potential range. the new sensor wasconstru...

the effects of camp-analogue dibutyryl-camp and anticalmodulin w-7 were studied on de novo synthesis and secretion of lipids in cultures of hepatoma mcardle rh7777 cells and normal rat hepatocytes. dibutyryl-camp and w -7 separately caused a significant decrease in the secretion of de novo synthesized triacyl [3h]glycerol in both cultures of mcardle cells and rat hepatocytes. the inhibitory eff...

an octahedral cobalt(iii) complex, trans-[(me2bpb)co(bzlan)2]clo4 (1), with h2me2bpb = n,n’-(4,5-dimethyl-1,2-phenylene)dipicolinamide and bzlan = benzylamine, has been synthesized and characterized by elemental analyses, ir, uv-vis, and 1h nmr spectroscopy. the structure of this complex has been determined by x-ray crystallography. the me2bpb2– is a di-anionic tetradentate ligand furnishing a ...

the electrochemical behaviour of lead electrode in hydrochloride solution containing variousoxo-anions at different concentrations was studied by using of cyclic voltammetry (cv) method.results obtained show that the addition of these inorganic compounds decreases the anodic andcathodic currents peaks according to the following order: h2po4- > hpo42-> so42-. it’s revealedalso that the cathodic ...

for a finite field $mathbb{f}_q$, the bivariate skew polynomial ring $mathbb{f}_q[x,y;rho,theta]$ has been used to study codes cite{xh}. in this paper, we give some characterizations of the ring $r[x,y;rho,theta]$, where $r$ is a commutative ring. we investigate 2-d skew $(lambda_1,lambda_2)$-constacyclic codes in the ring $r[x,y;rho,theta]/langle x^l-lambda_1,y^s-lambda_2rangle_{mathit{l}}.$ a...

background brucellosis is an important cosmopolitan infection disease caused by organisms belonging to the genus brucella. the cgt gene (cyclic β-1, 2 glucan transporter gene) is a virulent factor in brucella genus. the present study was conducted with the aim of cloning and expression of brucella cgt gene. materials and methods brucella melitensis cgt gene was amplified from extracted chromoso...

The large-scale extraction and partial purification of endogenous 3',5'-cyclic UMP, 3',5'-cyclic IMP and 3',5'-cyclic dTMP are described. Rat liver, kidney, heart, spleen and lung tissues were subjected to a sequential purification procedure involving freeze-clamping, perchlorate extraction, alumina and Sephadex ion-exchange chromatography and preparative electrophoresis. The samples thus obtai...
