background: weak efficacy of different fasciolicidal compounds used for treatment of paramphistomosis has drawn the attention of many authors to alternative drugs. the purpose of this study was to assess, for the first time, the effect of the methanolic extract of balanites aegyptiaca fruits (bae) on adult paramphistomum microbothrium . methods : the effect of bae on adult p. microbothrium afte...

Crocin, the main constituent of saffron (Crocus sativus L.), is a natural carotenoid which is known for its antioxidant activity. Liver as the organ that metabolizes many chemicals is one of the first position that is at risk of environmental pollutants. It is clear that compounds that exhibit antioxidant properties, scavenging of free radicals and inhibition of lipid peroxidation are expected ...

Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder. Various constituents including flavonoids with biological activities including free radical scavenging, anti-lipoperoxidation and anti-inflammatory have been isolated from hawthorn. Due to adverse effect of PCOS on ovarian vascular remodeling as well as PCOS-induced oxidative stress, we aimed to study the hawthorn’s berri...

An 'incremental form' of anisotropic damage constitutive equation is proposed both for brittle and ductile materials. Based on the concept of irreversible thermodynamics that damage processes are history independent coupled with irreversible energy dissipation, two types of definition for damage representation are established, known as damage tensor D and damage strain tensor nd, to describe co...

In this paper, charging induced damage (CID) to metalinsulator-metal-capacitor (MIMC), is reported. CID does not necessarily lead to direct yield loss, CID may also induce latent damage leading to reliability losses. The damage is caused by the build up of a voltage potential difference between the two plates of the capacitor. A simple logarithmic relation is discovered between the damage by th...

In this study, the salt weathering effects on engineering properties and weight loss potential of three types of granitoid rocks were investigated. Sodium and magnesium sulfates tests were performed on core and aggregate samples. The cyclic salt weathering tests on core samples were done up to 90 cycles, while these tests on aggregate samples were done up to 40 cycles. The results showed that d...

Composite RCS building frames integrate reinforced concrete columns with structural steel beams to provide an efficient solution for the design and construction of earthquake-resisting structures. In this paper, an optimization framework is developed for performance-based seismic design of planar RCS moment resisting frames. The objective functions are defined as minimizing the construction cos...

The aim of this study was to evaluate the potential use of a DNA comet assay, DNA fragmentation fluorimetric assay and reactive oxygen species levels as potential biomarkers of genome conditions of dental pulp stem cells (DPSCs) isolated from dog canine teeth. Mesenchymal stem cells were isolated from the dental pulp collected from dog teeth. The results obtained suggest the ideal moment for cl...

side effects of ciprofloxacin (cpfx), a widely used broad spectrum antibiotic with fluoroquinolone core, have been reported in different organs. in the present study we sought to elucidate the impact of ciprofloxacin on sperm chromatin integrity and sperm dna damage using aniline blue and acridine orange technique, respectively. the fertility potential in male mice was also evaluated. nmri male...

background: the current study aimed to evaluate the effects of phosalone (pln) as an organophosphate (op) compound on testicular tissue, hormonal alterations and embryo development in rats. materials and methods: in this experimental study, we divided 18 mature wistar rats into three groups-control, control-sham and test (n=6 per group). animals in the test group received one-fourth the lethal ...
