Background: Radio frequency wave (RFW) generated by mobile phones and wireless communication systems has been reported to cause adverse effects on reproductive function, vision and hematological parameters, possibly through oxidative stress. The aim of this study was to evaluate the effect of RFW generated bybase transceiver station BTS on oxidative stress in testis, eye and erythrocyte, and th...

objectives: liver is one of the most sensitive tissues to oxidant damage. hence, the present study was conducted to compare the effects of melissa officinalis (mo) extract and atorvastatin on the activity of liver enzymes in rats. materials and methods: in this experimental study, 60 male wistar rats were selected and allocated to six groups (n=10). the control group received a normal diet, sha...

to investigate the effect of droughtstress on chlorophyll content, enzymatic responses and some growth characteristics of acacia victoriae seedlings and the effect of super-absorbent polymers (sap) in reducing drought stress, a split plot experiment based on the completely randomized design was conducted. the treatments included four levels of drought stress (15, 30, 60 and 100% of field capaci...

drought is an important abiotic stress limiting plant performance. generation of reactive oxygen species (ros) is enhanced under stresses. two greenhouse experiments were conducted to evaluate the effect of phytohormones on the changes of antioxidant enzymes and carotenoids in petals of pot marigold (calendula officinalis l.) under drought stress. results showed that the activities of superoxid...

the aim of this reaserch was evaluathng the aluminum-sulphate concentration levels in preserved solution with stem recutting on longevity of rosa hybrida cv. varlon cut flowers. the investigation was conducted in horticultural lab,agriculturalcollege,zanjanuniversity. rose cut stems were produced in greenhouse from biennial mother stocks and were placed under the treatment of aluminum-sulphate ...

background: fasciola hepatica is one of the most important helminthes parasites and triclabendazole (tcbz) is routinely used for treatment of infected people and animals. secreted protease enzymes by the f. hepatica plays a critical role in the inva-sion, migration, nutrition and the survival of parasite and are key targets for novel drugs and vaccines. the aim of study was to determine the pro...

This study was conducted to determine effects of dietary administration of different levels of ginger (Zingiber officinale) extract on digestive enzymes activity and liver composition of Mesopotamichthys sharpeyi during eight weeks. In this respect, 192 M. sharpeyi fingerlings (with initial weight 11.67 ± 0.32 g) were divided into three ginger extract (0.1%, 0.5%, 1%) treatment group...

willow leaf beetle, plagiodera versicolora is an important pest of willow trees that feeds on the leaves both as larvae and as adults. -amylases (ec 3.2.1.1) are the major insect digestive enzymes that catalyze the endohydrolysis of long -1,4-glucan chains such as starch and glycogen. in the current study, -amylase activity was studied in the midgut of larvae and adults of p. versicolora. am...
