Objective- To investigate and compare growth potential as well as aging of mesenchymal stem cells (MSCs) derived from rat bone marrow tissue and adipose tissue (AT) occurred at epicardial and epididymal regions. Design- Experimental study.   Animals- 10 Wistar Rats.   Procedures- Rat MSCs occurred at bone marrow and epicardial and epididymal AT were isolated and culture expanded through sev...

Homologous serum, when repeatedly used for the culture of postimplantation rat embryos, rapidly loses its capacity to support growth and development. Replenishment of the 'exhausted' serum with glucose and vitamins (MEM vitamin concentrate--Flow Laboratories) together with gentle dialysis to remove small molecular weight toxic metabolites (lactate etc) fails to restore the growth-promoting prop...

During the course of a study of the effect of the oral administration of certain polycydic hydrocarbons on the growth of the rat,7 a paper by Haddow, Scott, and Scott2 appeared which reported that growth retardation had been produced in the rat by a single intraperitoneal injection of certain carcinogenic hydrocarbons. These authors further observed that similar injections of non-carcinogenic c...

Quantitation of D-beta-hydroxybutyrate dehydrogenase (BDH) in normal rat hepatocytes was compared with that in two rat hepatoma cell lines, H4-II-EC3 and RLT-3C. BDH activity in normal rat hepatocyte mitochondria was 321 nmol/min/mg, which was greatly reduced to 10.7 nmol/min/mg and 1.7 nmol/min/mg in H4-II-EC3 and RLT-3C cell mitochondria, respectively. The cell growth rate and L-[35S]methioni...

Quantitation of i>-/3~liy butvratc dehydrogenase (BDH) in normal rat hepatocytes was compared with that in two rat hepatoma cell lines, H4-II-EC3 and RLT-3C. BDH activity in normal rat hepatocyte mito chondria was 321 nmol/min/mg, which was greatly reduced to 10.7 nmol/ min/mg and 1.7 nmol/min/mg in H4-II-EC3 and RLT-3C cell mitochon dria, respectively. The cell growth rate and L-[35Slmet...

this experiment was conducted to evaluate the effects of salt stress on some agro-physiological traits in ten varieties of bread (triticum aestivum l.) and durum (triticum turgidum l.) wheats in seedling stage. a greenhouse experiment was carried out as a split plot experiment based on a completely randomized design with four replications in hydroponic condition. different agronomic and physiol...

one may find out the application‎ ‎of mathematics in the areas of ecology‎, ‎biology‎, ‎environmental‎ ‎sciences etc‎. ‎mathematics is particulary used in the problem of‎ ‎predator-prey known as lotka-volterra predator-prey equations.‎ ‎indeed‎, ‎differential equations is employed very much in many areas‎ ‎of other sciences‎. ‎however‎, ‎most of natural problems involve some‎ ‎unknown functions...

the main aim of this project was the assessment, for the first time, anthropometrically, the nutritional status in school girls' population aging from 7 to 10 years in ahwaz city and ultimately compare their growth rate with other findings obtained from different part of iran and also with the proposed standards of nchs in this respect. this study was conducted on 1200 apparently healthy school...

in the present study, seven isolates of haemophilus influenzae type b were cultured in four different media to compare growth rate and capsule production. four liquid media namely brain heart infusion broth (bhi), trypticase soy broth (tsb), mueller hinton broth (mhb) and gonococci broth (gc) with added supplements (1% hemoglobin, 1% isovitalex) were used. the growth was measured by colony coun...

in order  to study the effect of drought stress on some growth indices of oil sunflower cultivars, a study was conducted in isfahan. the experiment was conducted as split plots in a randomized complete blocks design with three replications in isfahan (51° 48' e, 32° 40' n).main plots were drought stress in four levels (80, 100, 120, and 140 mm evaporation from evaporation pan class a and cultiv...
