background: in this study, the inhibition rate of different oil concentrations containing pcbs (1242 and 1254 pcb arochlors) on the anaerobic biomass was investigated by specific methanogenic activity using the vials with volume of 120 ml. methods: original samples were divided into two groups: with soil containing pcbs and without pcbs and the control samples in both cases were just contained ...

objective: oxidative stress is involved in the pathophysiology of diabetes and cardiovascular complications of metabolic syndrome. the main objective of this study was to evaluate total antioxidant status by diphenylpicrylhydrazyl (dpph)-scavenging activity in patients developed metabolic syndrome (mets). materials and methods: forty-four patients with mets diagnosed on the basis of adult treat...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 one of the prominent types of connective tissue cells is fibroblast that synthesizes and maintains the extracellular matrix of many animal tissues. previous studies illustrated that calprotectin protein has different cytotoxicity effects on fibroblast cells. calprotectin is abundant in the neutrophil cytosol; it has growth...

essential oils and their components are becoming increasingly popular as naturally occurring antimicrobial agents. in this work the chemical composition and antimicrobial activity of ferula gumosa essential oils were determined. the essential oil components were identified by gc/ms analysis. the minimum inhibitory concentration (mic) of essential oil against five selected pathogenic microorgani...

purpose previous studies have shown that physical activity improves learning and memory. present study was performed to determine the effects of short term and long term treadmill exercise on learning, memory consolidation and retrieval of passive avoidance learning in an animal model. methods in this study fifty male wistar rats with 3-4 months of age were randomly divided into five groups (n=...

bacterial vaginosis (bv) has been considered to be the most prevalent infection found in sexually active women. bv is thought to play an important role in the premature rupture of membranes (prom) and preterm birth. preterm delivery accounts for a substantial percentage of low birth weight infants and perinatal mortality and morbidity. bacteroides and prevotella species have been isolated from ...

osteoporosis is a disease of high prevalence with increased bone loss. it has potential public health threat and that the health authorities had taken several measures for its control. in recent years, considerable attention has been given to physiopathology of osteoporosis. oxidative stress has been proved to be involved in bone resorption. oxidative stress occurs when balance between oxidants...

a new series of thiazolidinedione derivatives were synthesized. the structures of these compounds were established by means of ir, 1h-nmr and elemental analysis. all of the compounds were screened for antidiabetic activity on albino rats. most of the compounds showed significant antidiabetic activity when compared with the standard drug glibenclamide.

materials and methods the expression of hyaluronidase antigenic fragments was optimized using iptg concentration, time of induction, temperature, culture, and absorbance of 0.6-0.8-1 at 600 nm. afterwards, the expressed proteins were purified and the enzymatic activity was assessed by turbid metric method. results data indicated that maximum protein is produced in od = 0.8, 0.5 mm isopropyl β-d...

background:  physical activity is a complex behavior. to designing the effective intervention, qualitative researches may be allowed for greater understanding of the reasons behind the adolescences’ physical activity‑related behaviors’. methods: using the grounded theory approach, including semi‑structured focus group discussions  (fgds) and in‑depth interviews, we conducted a quantitative stud...
