Phytochemical content, antioxidant properties, and antibacterial activities of L.

The present study is an evaluation of ethanolic extract in terms of total phenolic content, total flavonoids, total flavonols, anthocyanin, antioxidants, and antibacterial activities. plants were collected from Guilan province, Iran. High-performance liquid chromatography-Diode array detector analysis demonstrated that the ethanolic extract of contained phenolic substances such as sinapic acid, catechin, quercetin, p-coumaric acid, hesperidin, eugenol, and hesperetin.

The role of melatonin on caspase-3-like activity and expression of the genes involved in programmed cell death (PCD) induced by in vitro salt stress in alfalfa (Medicago sativa L.) roots.

Background: Alfalfa (Medicago sativa L.) is the most cultivated forage plant as a model in legumes. Salinity stress due to Na toxicity causes severe, oxidative stress as a main reason for program cell death (PCD) in plants.

Association of sleep-disordered breathing with severe chronic vascular disease in patients with type 2 diabetes.

Background: Severe chronic vascular disease (CVD) is a major cause of co-morbidity and mortality in patients with type 2 diabetes (DM2). Sleep-disordered breathing (SDB) has been linked to CVD in the general population due to enhanced sympathetic activation, oxidative stress, endothelial dysfunction, and hypertension; however data for DM2 patients is scarce. Therefore, the aim of the present analysis to assess whether SDB is associated with CVD in patients with DM2, independent of other known associated factors.

Prevalence of vitamin D deficiency and its related factors in children and adolescents living in North Khorasan, Iran.

Introduction: Vitamin D deficiency is recognized as an epidemic among children. The present study has analyzed serum 25 hydroxyvitamin D [25(OH)D] levels of children living in the city of Bojnurd, located in the North Khorasan province of Iran.

Methods: In this cross-sectional study, 361 subjects (175 boys and 186 girls) aged 7-18 years participated; 25(OH)D, parathyroid hormone (PTH), and anthropometric measurements were obtained.

Histopathological observations on protective effects of vitamin E on endosulfan induced cardiotoxicity in rats.

The protective effects of vitamin E was investigated on the cardiotoxicity induced by endosulfan administration. Male rats in different groups were given endosulfan (2 mg per kg body weight per day in corn oil through gavage), vitamin E (200 mg per kg body weight twice a week in corn oil through gavage) and endosulfan and vitamin E at the same dose and route, to the control group corn oil is given at the dose rate of 2 mL per rat per day through gavage, for a period of28 days. The animals were sacrificed and heart tissues were collected and subjected to histopathology.
