BACKGROUND Characterisation of stem cells by flow cytometry, their expansion and differentiation are presently of major interest for cell engineering as the basis of a therapeutic concept for transplantation. Haematopoietic stem cells (HSC) express CD34, the adhesion structure which binds 2L-selectin, CD117, a receptor for stem cell factor (SCF; c-kit(More)
BACKGROUND Umbilical cord blood cells (stem/progenitor cells) exhibit high proliferative capacities leading to a large expansion of cells in appropriate cell culture conditions. The aim of this study was to evaluate by flow cytometry the cycling status of CD133+ and CD133- cells depending on various culture conditions, such as sera, stem cell factor (SCF),(More)
Acetylcholinesterase (AChE) is responsible for the rapid hydrolytic degradation of the neurotransmitter acetylcholine into inactive products choline and acetic acid. The purpose of this study was to examine the effect of carbaryl and dichlorvos on the activity of AChE. In this experimental study, 60 samples of free and immobilized form of AChE were(More)
The aim of the present study was to evaluate the effect of commercial monostrain and multistrain probiotics in diets on growth performance, intestinal morphology and mucin gene (MUC2) expression in broiler chicks. Three hundred seventy-eight 1-d-old male Arian broiler chicks were allocated in 3 experimental groups for 6 wk. The birds were fed on a(More)
Serum glutathione peroxidase (GSH-Px) activity and selenium concentration were compared in intrinsic asthmatic patients and non-asthmatic control subjects. Serum GSH-Px activity and selenium concentration were assessed in 46 asthmatic patients and 75 age- and sex-matched non-asthmatic subjects by spectrophotometric assay. Mean serum GSH-Px activity was(More)
OBJECTIVES Determine the Low-density lipoprotein cholesterol (LDL-C), High-density lipoprotein cholesterol (HDL-C) and serum total homocysteine in myocardial infarction patients and control subjects. DESIGN AND METHODS The study group consisted of 126 patients 67 male, and 59 females, aged 29-73 (mean 48.65 +/- 3.81) years. The entry criteria for the(More)
Transaminase activity and serum total protein level were investigated in adult rats after oral treating with sodium fluoride at three doses, 10, 20 and 30 mg/kg daily for 90 days. After 90 days, the average total serum protein level of the rats in the treatment group decreased significantly compared with that in the control [1.9 +/- 0.1 (mean +/- S.D., n =(More)
BACKGROUND AND AIM Non-invasive methods have been proposed as surrogate markers for liver biopsy. It was shown that serum hyaluronic acid (HA) and laminin (LN) levels increase with the development of liver fibrosis. The aim of this study was to determine serum HA and LN levels cut-off points for predicting liver fibrosis, highlighting their diagnostic value(More)
BACKGROUND This investigation describes the relationship between glutathione peroxidase activities, an antioxidant enzyme, and the oxidative status in diabetic rat blood. METHODS Malondialdehyde level and glutathione peroxidase activity were measured by spectrophotometric techniques. RESULTS AND CONCLUSIONS Malondialdehyde content in the diabetic rats(More)
Urtica dioica has been known as a plant that decreases blood glucose. Despite the importance of this plant in herbal medicine, relatively little research has been down on effects of this plant on islets yet. The objective of the current study was to evaluate the effect of dried Urtica dioica leaf alcoholic and aqueous extracts on the number and the diameter(More)
