People's Voice and Civil Society Participation as a Core Element of Universal Health Coverage Reforms: Review of Experiences in Iran.

Health governance challenges can make or break universal health coverage (UHC) reforms. One of the biggest health governance challenges is ensuring meaningful participation and adequately reflecting people's voice in health policies and implementation. Recognizing this, Iran's Health Transformation Plan (HTP) lays out the country's blueprint for UHC with an explicit emphasis on the 'socialization of health.

Molecular mechanisms of vitamin D plus Bisphenol A effects on adipogenesis in human adipose-derived mesenchymal stem cells.

Background: Obesity is considered a major health concern and mounting evidence suggests that the exposure to environmental endocrine disruptors, including Bisphenol-A (BPA), may enhance the risk to develop the disease. Moreover, growing documents propose that the vitamin D may contribute to adipogenic signaling and lipid accumulation during adipocyte differentiation. We focused on the molecular mechanism of vitamin D and BPA in human adipose-derived mesenchymal stem cells (hADMSCs) which vitamin D and BPA may influence adipose tissue development and function.

1,25-Dihydroxyvitamin D3 modulates adipogenesis of human adipose-derived mesenchymal stem cells dose-dependently.

Purpose: 1,25-dihydroxyvitamin D3 may regulate adipogenesis in adipocytes in-vitro, but little is known about possible molecular mechanisms related to the inhibitory effect of 1,25-dihydroxyvitamin D3 on adipogenesis in humans҆ adipose tissue.

Methodology: In this study, human adipose-derived mesenchymal stem cells (hASCs) were cultured for 14 days in adipogenic differentiation media containing concentrations of 1,25-dihydroxyvitamin D3 (10-10 M). The extent of adipogenic differentiation in ASCs was assessed by Oil Red O staining and quantitative polymerase chain reaction (PCR) to determine expression levels of key adipogenic markers.

Background: The purpose of this study was to examine the influence of hand-forearm anthropometric dimensions on handgrip and pinch strengths among 7-18 years children and adolescents and to investigate the extent to which these variables can be used to predict hand strength.

Methods: Four types of hand strengths including handgrip, tip to tip, key, and three-jaw chuck pinches were measured in 2637 healthy children and adolescents (1391 boys and 1246 girls) aged 7-18 years using standard adjustable Jamar hydraulic hand dynamometer and pinch gauge. A set of 17 hand-forearm anthropometric dimensions were also measured with an accurate digital caliper and tape measure.

Bisphenol A enhances adipogenic signaling pathways in human mesenchymal stem cells.

Background: The endocrine disruptor Bisphenol-A (BPA), has been involved in dysregulating adipose tissue development and increasing the risk of obesity. The objective of this experiment was to investigate whether treatment of human mesenchymal stem cells with BPA could modulate adipogenesis and adipocyte differentiation.

Methods: In this experimental study, the human adipose-derived mesenchymal stem cells (hASCs) were cultured for 2 weeks with continuous exposure to 10 M or 10 M concentrations of BPA.

Health needs assessment of workers in Kaveh industrial city.

Health needs assessment (HNA) is essential for allocation of limited resources to the most prioritized problems. HNA in work places has gained increasing importance. Kaveh industrial city is the largest and oldest industrial city in Iran, with a wide range of different industries, making it an exemplary industrial city in Iran.

Development of a national conceptual framework and measuring tool for Organisational Social Responsibility and Accountability for Health (OSRAH).

Organisations can have a significant impact (positive or negative) on society through their actions and decisions. Given this reality, it is important that they are held responsible and accountable for the consequences of their actions. This concept is often referred to as 'social responsibility'.
