background: alzheimer’s disease (ad) is a progressive neurodegenerative disease and nowadays the role of endothelial cell (ec) injury has been proposed in pathological process in ad. peroxisome proliferator‑activated receptor‑γ (ppar‑γ) agonist has anti‑inflammatory properties through activation in glial cells and improves vascular function and prevent atherosclerotic disease progression. the a...

objective(s): pesticides has wide range of infertility in female reproductive. this study was done to evaluate the effect of movento pesticide on development of granulosa cells and ovarian follicles and foxo1 and vnn1 gene expression in balb/c mice. materials and methods: in this study 40 healthy balb/c mice 5-6 weeks age were used. animals were randomly allocated into four groups. control (wit...

apoptosis is a complex network of biochemical and molecular pathway with fine regulatory mechanisms that control the death event during several pathological situations in multi cellular organisms. it is the part of normal development that occurs in a variety of diseases and is known as aberrant apoptosis. pancreatic β cell apoptosis is also a pathological feature which is common in both type 1 ...

background apoptosis or programmed cell death is an essential process for elimination of damaged cells. also, induction of apoptosis is fundamental for treating cancer. screening for agents that induce apoptosis in tumor cells help in the development of novel agents for cancer treatment. numerous studies suggest that the exposure of tumor cells to statins can lead to cell death via two separate...

black seed (nigella sativa) is considered as a biological response modifier. thymoquinone (tq) is the bioactive and the most abundant constituent of the volatile oil of this seed which has been shown to possess anti-inflammatory, antioxidant and anti-neoplastic effects. in this study, the effect of tq on hepg2 cell line was investigated in an attempt to identify its potential mechanism of actio...

objective(s): artemisia is a genus of herbs and small shrubs forms an important part of natural vegetation in iran. it has been reported that several artemisia species possess anti-proliferative effects. considering the value of this genus in anti-cancer researches we have chosen artemisia biennis for cytotoxic and mechanistic studies. materials and methods:in this study we have investigated th...

Introduction: In this study, we explore in detail cell-specific targeting efficacy of nano-photo-thermal therapy (NPTT) method and the resulting responses that are induced by variable laser intensities and exposure times in cancer cells to induce selective apoptosis. We delineate the synthesis of a high-yielding synthetic F-AuNPs by tailoring the surface of gold nanoparticles ...

objective(s): the study aimed to investigate the effects of resveratrol on colorectal cancer hct116 cells, including cell viability, apoptosis, and migration, and the partial mechanisms focused on hedgehog/gli-1 signaling pathways. materials and methods: we chose the appropriate time and concentration of recombinant human sonic hedgehog (shh) stimulation by cell viability. the proportion of cel...

the p75 pan-neurotrophin receptor (p75ntr) plays a pivotal role in linking the immune system with the nervous system. p75ntr is required for the development of several characteristic features of allergic asthma. also p75ntr upregulated by reactive schwann cells after peripheral nerve injury. moreover p75ntr and rhoa play a critical role in the regulation of apoptosis. to determine whether the d...

objective(s): in the current study antioxidant capacities of five different extracts of artemisia ciniformis aerial parts were evaluated by cell-free methods. then seven fractions of the potent extract were selected and their antioxidant capacity was assayed by cell free and cell based methods. materials andmethods: antioxidant ability was measured using the: 2, 2-diphenyl-1-picrylhydrazyl (dpp...
