مقدمه: در سال های اخیر، اطلاعات کمی از شیوع آفلاتوکسین در آرد و مقایسه ی آن در نان های سنتی و حجیم موجود در بازار منتشر شده است. در پژوهش حاضر، حدود آلودگی به آفلاتوکسین در برخی از محصولات نانوایی و ارزیابی خطر دریافت آن مورد بررسی قرار گرفت. روش ها: در این مطالعه ی مقطعی- تجربی، 66 نمونه شامل 29 نمونه ی مختلف آرد ستاره، 14 نمونه ی نان سنتی، 10 نمونه ی نان حجیم و 13 نمونه ی مغز برای تزیین نان ب...
zero tillage practices have a direct effect on soil microbial communities modifying soil productivity and sustainability. the crop sequences used can change the aforementioned properties, too. in this study, we evaluated the effect of crop sequences under zero tillage management on soil biological and chemical properties including vertical distribution of soil organic carbon, soil basal respira...
background and objectives: sodium dodecyl sulfate (sds) is one of the main surfactant components in detergents and cosmetics, used in high amounts as a detergent in products such as shampoos, car wash soap and toothpaste. therefore, its bioremediation by suitable microorganisms is important. alkylsulfatase is an enzyme that hydrolyses sulfate -ester bonds to give inorganic sulfate and alcohol. ...

background herpes simplex virus type 1 and type 2 (hsv-1 and hsv-2) are common infectious agents worldwide. data on prevalence of hsv-1 and hsv-2 infections are limited in asia, especially in iran. our study aimed on determination of seroepidemiology of hsv-1 and hsv-2 infections in asymptomatic healthy students of islamic azad university of kazeroun, fars province, southwest of iran. patients ...
abstract- olive (olea europaea l.) is one of the most valuable and widespread fruit trees in iran. salt stress-induced changes in membrane stability, photosynthesis and antioxidant enzyme activity were examined on four olive cultivars (dakal, shiraz, zard and amigdalifolia) by emphasizing the correlation between measured parameters and ion (k+, na+) accumulation. plants were subjected to four s...
objective(s): nanotechnology and nanoparticles are increasingly recognized for their potential applications in aerospace engineering, nanoelectronics, and environmental remediation, medicine and consumer products. more importantly is the potential for the application of silver nanoparticles (ag nps) in the treatment of diseases that require maintenance of circulating drug concentration or targe...
slurries of rice-straw cellulose (obtained by delignification and removal of hemicelluloses from the powdered raw material) were subjected to ultrasonic waves at different intensities for various times (constant temperature). susceptibility of the samples to cellulose-hydrolysis increased initially with pretreatment time, reaching a maximum or a constant level thereafter. maximum glucose yield ...
results low concentrations of agnps and short incubation times can have the maximum positive impact on the peroxidase activity, and in the present study the highest activity was seen at a concentration of 40 mg/l and two hours of incubation time. conclusions this study suggests that changes of enzyme activity can occur as a result of the effect of silver nanoparticles on enzyme conformation, in...
results: of the 50 samples tested by the elisa method, 26 samples (52%) were positive for igg . no samples were positive for igm. of the 50 samples tested by the chemiluminescence method, 28 samples (56%) were positive for igg. no samples were positive for igm. conclusions: a significant relationship between the age of the youngest child and the infection rate was seen. no significant correlati...
