background: diazinon (dzn) is an organophosphate insecticide widely utilized in agriculture all over the world and causes many negative effects on plants and animal species, especially on human. the aim of present study was to evaluate the effects of dzn on apoptosis of ovarian follicles in adult rats and to assess the protective role of vit e. methods: thirty adult female wistar rats were divi...

background helicobacter pylori is responsible for one of the most common human infections and is a major risk factor for stomach ulcer disease and gastric cancer. h. pylori infection has been reported to be associated with generation and development of coronary artery disease (cad). moreover, diabetic patients positive for h. pylori infection showed a higher prevalence of cad compared to h. pyl...

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): The role of aluminum (Al) in the pathogenesis of neurodegenerative diseases has been implicated in several studies. However, the exact mechanisms of cytotoxic effects of Al have not been elucidated yet. The aim of this study was to investigate the effect of L-type calcium channel antagonist, nimodipine (NM), and lithium chloride (LiCl) on Al-induced toxicity in PC12 cells. Materia...

The protective effects of Rheum tanguticum polysaccharide 1 (RTP1), which is extracted from the Chinese traditional medicine Rheum tanguticum, on radiation-induced intestinal mucosal injury was investigated. Rat intestinal crypt epithelial cells (IEC-6 cells) and Sprague-Dawley rats were each divided into control, irradiated and RTP1-pretreated irradiated groups. After irradiation, cell surviva...

objective(s):  the role of the apoptosis repressor with caspase recruitment domain (arc) in apoptosis and in certain hypertrophic responses has been previously investigated, but its regulation of endothelin-1 induced cardiac hypertrophy remains unknown. the present study discusses the inhibitory role of arc against endothelin–induced hypertrophy. results:in present study endothelin treated card...

Apoptosis is the natural programmed cell death process, which responsible for abnormal clearance. However, many cancer cells develop various mechanisms to escape apoptosis through interrupting apoptosome assembly, a key step initiate apoptosis. This promotes tumorigenesis and drug resistance, thus, poses great challenge in treatment. Herein, biomimetic lipid nanocarrier mimicking mitochondrial ...

Objective(s): Aberrant expression of CCL5 has been found in several kinds of inflammatory diseases, and the roles of CCL5 in these diseases have also been reported. However, the role of CCL5 in infantile pneumonia is still unclear. Thus, the function and acting mechanism of CCL5 in the in vitro model of infantile pneumonia were researched in this study. Materials and Methods: Human fetal lung f...

Introduction: Lead toxicity induces retinal cell apoptosis. Vitamin C and garlic may decrease lead-induced apoptosis. This study was undertaken to investigate vitamin C and garlic protective effects on lead-induced apoptosis in eye retina. Methods: Pregnant Wistar rats (n = 72) were divided randomly into 9 groups: (L) treated rats with lead acetate in drinking water and (L+AA) with leaded water...

Background: Aluminum (Al) exposure is among the environmental risk factors that may involve in the pathogenesis of neurodegenerative diseases. Oxidative stress has a critical role in the Al-induced toxicity. Saffron is a plant with potent radical scavenging and anti-oxidative properties. This investigation was designed to evaluate the possible protective effects of saffron extract (SE) on alumi...
