As a contributing factor to health, the trace element selenium (Se) is an essential nutrient of special interest for humans and all animals. It is estimated that 0.5 to 1 billion people worldwide suffer from Se deficiency. In spite of the important role of Se, its concentrations in soil, water and essential crops have not been studied in Iran. Therefore, the main aim of the current study was to...

OBJECTIVE To assess the relationship between selenium (Se) concentration in rice and the incidence of esophageal cancer (EC) in a high risk area in Northern Iran. METHODS This ecological study was conducted in Golestan province of Iran in 2012. In this area, 45714 acres of land are cultivated by rice. A total of 69 rice samples were taken. We investigated Se concentrations by the voltammetric...

specific elements (cr, al, ca, and si) and loss on ignition (loi) were used for semi-quantitative determination of the normative mineralogical composition of naturally occurring chromium ores in ophiolite complexes. by far the occurring ore minerals are complex both from the mineralogical and chemical viewpoints. the secondary minerals serpentine and cr-containing chlorite (kaemmererite) form n...

PROJECT Golestan province, located in northeast of Iran, has been known as a high risk area for esophageal cancer (EC). This study was conducted to assess the relationship between soils selenium (Se) level and development of EC in this region. PROCEDURES In this ecological study, 135 blocks were identified in Golestan province based on geographical altitude and longitude on the map. One soil ...

ten chromite ores from ophiolite complexes in se iran were analyzed mineralogically by xrd, chemically by xrf, and mineral chemistry by epma. the identified paragenesis of silicate minerals of chromite ores with the x-ray diffraction is pronounced differently. it consists of secondary phases formed as serpentine, cr-containing chlorite (kaemmererite), chromic garnet (uarovite) with preserved pa...

BACKGROUND Self esteem (SE) and organizational commitment (OC)? have significant impact on the quality of work life. AIM This study aims to gain a better understanding of the relationships between SE and OC among health information management staff in tertiary care hospitals in Tehran (Iran). METHODS This was a descriptive correlational and cross sectional study conducted on the health info...

The socioeconomic (SE) status is considered to be one of the most important health risk factors nowadays. A simple search showed that only in 2011, more than 1100 articles were cited in Pubmed about the relationship of health and SE status. However, there are many inquiries about this association. The SE status is a complex and multidimensional issue, and there is no gold standard method to mea...

Abstract The Main Recent Fault (MRF) is a major active strike-slip fault system at the NE border of Arabian platform and Central Iran. Both geometry kinematics rather well known along its central part SE termination, while possible continuation to northwest ambiguous. Moreover, less regard has been paid relationships between this intracontinental other faults in NW Iran – Anatolia. This paper i...
