Previous studies show that aberrant synthesis of Hyaluronan accelerates tumor growth, angiogenesis, and metastasis. The fibroblasts are probably responsible for most of the hyaluronic acid (HA) accumulation in tumor microenvironment after radiotherapy. Our goal is to investigate and compare radiation and lactate effects on HA levels in supernatant and exosome isolated from supernatant of primary mouse fibroblast cell culture.

Fibroblast cells were prepared from skin of C57BL6 mouse. These cells were divided into three groups (no treatment, cells treated with 10 mM ammonium lactate, and irradiated cells). Then supernatant was harvested from FBS-free culture media after 48 h. Exosomes were purified by differential centrifugation (300 × g for 10 min, 2000 × g for 30 min, 16500 g for 30 min) and were pelleted by ultracentrifugation (150,000 × g for 180 min). Size of exosomes was determined using a Zetasizer. HA concentration measured using a HA ELISA Kit. Data were analyzed using one-way ANOVA.

There was a significant increase in HA-coated exosomes isolated from supernatants of irradiated cells compared to untreated cell and cells treated with 10 mM ammonium lactate (

< 0.001). As well, there was a significant increase in the HA concentration in the supernatants of cells treated with 10 mM ammonium lactate relative to untreated cells and irradiated cells (

< 0.05).

It seems that routine radiation therapy leads to massive shedding of HA-coated exosomes by normal fibroblast cells and thus exosomes-HA may contribute to tumor promotion and induce of the premetastatic niche.

Recent studies show that Iranians, especially women, do not have enough physical activity and if serious measures are not taken to resolve this problem, the consequences will be harmful to the society. The purpose of this advocacy paper was to determine and explain the responsibilities of all organizations and institutions responsible for promoting physical activity to root out the problem.

After a thorough library search we conducted nine in-depth interviews with the relevant policymakers and government officials, managers, and practitioners in promoting physical activity. All interviews were recorded. To analyze, all of voice files were typed, saved as Word files, and exported to MAXQDA10 software by the research team. To find the main themes, all the files were read carefully several times. Then they were coded, categorized, and organized based on the main objectives of the study. In this way, themes and subthemes were emerged.

According to the participants in the study current state of physical activity in the country, especially among women, is not promising. The participants explained about the main obstacles for promotion of physical activity in the country and recommended practical strategies for its promotion. The strategies were suggested in three areas Promoting culture, social protection, and adjusting current policies to overcome the existing barriers.

Regarding the unfavorable state of physical activity in the country presentation of this advocacy document can be an effective step in promoting physical activity, thus reducing chronic diseases and improving general health in the country.

This study aims to determine the factors affecting the tendency to lose weight (TLW) and its methods in Iranian children and adolescents.

In this cross-sectional nationwide study 14800 students, aged 7-18 years, living in 30 provinces of Iran were selected via multistage cluster random sampling method. The dietary and physical activity habits and TLW as well as psychosocial health status, anxiety, self-satisfaction, and change in dietary behaviors were assessed by the global school-based student health survey (WHO-GSHS) questionnaire. Multivariate logistic regression model was used to identify factors influencing TLW.

Overall, 14274 students (participation rate of 99%), consisting of 51% boys and 71.4% urban residents, completed the study. Ilginatinib molecular weight Of them, 37.7% (51.4% Girls and 48.6% boys) tended to lose weight. In multivariate model, the odds for TLW was 12% higher in students aged 13-18 years than those aged 6-12 years (OR = 1.12, 95% CI 1.02 to 1.23;

< 0.001). Students with high anxiety level were 43% more likely to have TLW (OR = 1.43, 95% CI 1.28-1.59;

< 0.001). The odds of increasing physical activity for weight loss was 22% lower in obese than in normal weight students (OR = 0.78, 95% CI 0.66 to 0.93;

< 0.001).

TLW was significantly higher in girls, as well as in those with higher anxiety level. In addition to dietary change, increasing physical activity should be encouraged among children and adolescents with excess weight. Public education regarding proper lifestyle change for reaching healthy weight should be underscored.

Cardiovascular disorders (CVD) are a common cause of mortality worldwide. Oxidative stress is thought to be a major factor leading to CVD. Anti-oxidants such as medicinal plants may have a role in the mitigation of vascular problems through free radicals scavenging. In this study, we evaluated the protective effects of

against hydrogen peroxide (H

)-induced toxicity in endothelial cells (BAE-1).

To evaluate the protective effect of

against H

toxicity, four groups comprised of control group (the cells without any treatment), H

group (the cells incubated with H

O

200 μM)), and treatment groups (the cells treated with
