Effect of red beetroot juice on oxidative status and islet insulin release in adult male rats.

Introduction: Beetroot is rich in inorganic nitrate and it has been shown that inorganic nitrate has beneficial effects on metabolic syndrome. This study aims to investigate the effect of red beetroot juice (RBJ) on carbohydrate metabolism in adult insulin-resistant rats.

Materials And Methods: Sixteen male Wistar rats (32 weeks old) were divided into two equal groups: control and RBJ.

Age- and sex-specific reference intervals for superoxide dismutase enzyme and several minerals in a healthy adult cohort.

Introduction: The aim of this study was to establish RIs for clinically important markers including superoxide dismutase (SOD), serum copper, zinc, calcium, magnesium, and phosphate in a cohort of healthy Iranian adults.

Materials: A subsample from MASHAD cohort study was used to assess serum SOD, copper, zinc, calcium, magnesium and phosphate. Serum SOD was measured according to its inhibitory potential of pyrogallol oxidation.

Age and sex-specific reference intervals for prooxidant-antioxidant balance, anti-heat-shock protein 27 (anti-hsp27), and routine laboratory tests in the middle-aged adult population.

Introduction: We aimed to define specific reference intervals (RIs) for 11 biomarkers including inflammatory and oxidative stress biomarkers, liver, and renal function tests in a healthy Iranian adult population for the first time.

Methods: CLSI Ep28-A3 guidelines were then used to calculate accurate age- and sex- as well as body mass index (BMI)-specific RIs.

Results: RIs for studied biomarkers showed no significant age and sex-specific differences, except for uric acid, which had higher concentrations in men when compared to women.

Reference intervals for routine biochemical markers and body mass index: A study based on healthcare center database in northeastern Iran.

Age- and sex-specific reference intervals (RIs) for some biochemical tests may be useful for their interpretation, due to the variations in lifestyle and genetic, or ethnic factors. The aim of this study was to obtain RIs for some routine biochemical markers including a serum lipid profile, fasting blood glucose (FBG), aspartate and alanine aminotransferase (AST and ALT), uric acid, and body mass index (BMI) in subjects who attended primary healthcare centers. The large database of primary healthcare centers uses RIs to report results for children, adolescents, and young and old adults.

Serum Pro-oxidant-antioxidant Balance in Subjects with Type 2 Diabetes Mellitus.

Aim And Objective: Diabetes mellitus is associated with inflammation and increased oxidative stress. In the current study, we aimed to investigate the relationship between type 2 diabetes mellitus (T2DM) and serum pro-oxidant-antioxidant balance (PAB) in a large populationbased study.

Methods: In this cross-sectional study, 7888 individuals were recruited as part of the Mashhad Stroke and Heart Atherosclerotic Disorders (MASHAD) cohort study.

Comprehensive laboratory reference intervals for routine biochemical markers and pro-oxidant-antioxidant balance (PAB) in male adults.

Background: Reference values of biochemical markers are influenced by various parameters including age, sex, region, and lifestyle. Hence, we aimed to determine age- and BMI-specific reference intervals (RIs) for important clinical biomarkers in a healthy adult male population from northeastern Iran. This is also the first study to investigate reference values for pro-oxidant-antioxidant balance (PAB).

Evaluation of ABO blood group in subjects with CVD risk factors in a population sample from northeastern Iran.

Background And Aims: The ABO blood group system is a genetic polymorphism which can affect the clearance of von Willebrand factor. We aimed to assess the levels of newer biomarkers of cardiovascular disease (CVD) risk; pro-oxidant-antioxidant balance (PAB), high sensitivity C-reactive protein (hs-CRP) and anti-heat-shock protein27 (anti-Hsp27) antibody titers in subjects with various blood groups (A, B, AB and O) and with or without traditional CVD risk factors.

Methods: The cross-sectional study comprised 6910 subjects.

Comprehensive hematological reference intervals in a healthy adult male population.

Reference intervals (RIs) are important tools for improving medical decision-making. Hematology reference values can be influenced by important covariates such as genetic and environmental factors, rendering it essential to define RIs for specific populations. Therefore, we aimed to establish accurate and robust RIs for hematological markers in a healthy adult male Iranian population.

Association between obesity categories with cardiovascular disease and its related risk factors in the MASHAD cohort study population.

Background: Cardiovascular disease (CVD) is a significant cause of morbidity and mortality globally. Obesity is an important CVD risk factor and is increasing in prevalence.

Methods: In this study, 3829 men and 5720 women (35-65 years) were enrolled as part of the MASHAD cohort study.

Association between dietary inflammatory index and risk of cardiovascular disease in the Mashhad stroke and heart atherosclerotic disorder study population.

The dietary inflammatory index (DII) is a novel way of describing diet that has been studied in relation to various health conditions, including cardiovascular disease (CVD) in several populations. We aimed to investigate the association between DII and CVD events among a representative population sample in northeastern Iran. This prospective cohort study was a subsample of 4,672 adults aged 35-65 years, and recruited as part of Mashhad stroke and heart atherosclerotic disorder cohort study population.

Prevalence and causes of severe visual impairment and blindness among children in the lorestan province of iran, using the key informant method.

Purpose: To estimate the prevalence and causes of severe visual impairment and blindness among children in Lorestan province of Iran, and to assess the feasibility of the Key Informant Method in this setting.

Methods: Potential cases were identified using the Key Informant Method, in 3 counties of Lorestan province during June through August 2008, and referred for examination. Causes of severe visual impairment/blindness were determined and categorized using standard World Health Organization methods.

Refractive error and axial length in nonarteritic anterior ischemic optic neuropathy.

Purpose: The aim of this study was to evaluate the ocular axial length and refractive error as risk factors for development of nonarteritic anterior ischemic optic neuropathy (NAION).

Methods: This prospective study included 78 patients with NAION and 80 normal volunteers. Axial length and refractive error of NAION eyes were compared with the normal fellow eyes and control eyes.
