RESUMO
HLA class I and II alleles have been studied in a population from Gorgan (North East Iranian city bordering Turkmenistan). This population is composed of mainly Turkmen who speak Oghuz Turkish language. Comparison of Gorgan people HLA profile has been carried out with about 7984 HLA chromosomes from other worldwide populations; extended haplotypes and three dimension genetic distances have been calculated by using neighbor-joining and correspondence relatedness analyses. Most frequent extended HLA haplotypes show a Siberian/Mediterranean admixture and closest populations are Chuvashians (North Caspian Sea, Russia) and other geographically close populations like Siberian Mansi, Buryats and other Iranians. New extended HLA haplotypes have been found, such as: A*31:01-B*35:01-DRB1*15:01-DQB1*03:01, A*01:01-B*35:01-DRB1*03:01-DQB1*02:01. Relationships of Turkmen with Kurgan (Gorgan) archaeological mounds, Scythians and Sarmatians are discussed. This study is also useful for a future transplantation Gorgan waiting list, Gorgan HLA and disease epidemiology and HLA pharmacogenomics.

The Turkmen horse is one of the oldest breeds in the world with unique characteristics in agility, endurance and jump, being publicly acclaimed. Laminitis affects the limbs and decreases athletic performance. Radiographic evaluation is essential to confirm the sinking diagnosis in every breed of a horse suffering from laminitis. Since no information about distal phalanx radiographic measurements in this breed has been reported, the current study was designed and conducted. In the present study, 24 clinically sound registered Turkmen horses of both sexes (15 mares and nine stallions) were selected. Lateromedial radiographic views of both front distal phalanges were taken, focusing on the distal phalanx. After magnification correction, images were used to measure founder distances (FD) and other distal phalanx radiographic measurements using an image processing program. There was no significant difference between radiographic measurements of the left and right front feet. The FD had a significant positive correlation with weight. The horses under 3 years of age had a significantly greater U angle than the horses over the age of three. Also, palmarocortical length (PCL) in the Turkmen stallions was significantly higher than mares. In this investigation, PCL in horses under the age of three was significantly lower than horses over 3 years of age. The values determined in this study can be used as baseline data of front feet in Turkmen horses.
RESUMO
BACKGROUND: Smokeless tobacco (SLT) products are gaining popularity around the globe, particularly in Asia, Africa, and the Middle East. Among these products, Nass (aka Naswar) is popular among the Turkmen ethnicity in Iran. Although several studies reported nicotine dependence (ND) among SLT users, psychometric instruments have never been utilized to specifically measure ND among Nass users. Therefore, in this study, we aimed to evaluate the reliability and validity of the Fagerström Tolerance Questionnaire (FTQ) among Turkmen Nass users. METHODS: A cross-sectional, descriptive study was conducted in June-December 2018 among 411 Turkmen adults who currently (past 30 days) used Nass. Two bilinguals (Persian English) individuals translated and back-translated the FTQ-SLT, which maintained both the questionnaire's accuracy and cultural sensitivity. Construct validity was assessed using exploratory and confirmatory factor analysis. RESULTS: The mean age and standard deviation for initiating Nass were 22.5 ± 11.81 years. Exploratory and confirmatory factor analysis indicated a single-factor solution with 8-items that captured several important ND components. Using Nass frequently, soon after waking, when sick, and experiencing a craving were some of the main components. Subgroups comparison revealed that higher scores occurred among those who were married, had Nass user(s) in their immediate family, and consumed bulk form of Turkmen Nass directly without using a tissue. CONCLUSION: Our findings show that the FTQ- SLT is a fairly reliable and valid scale to measure ND among Turkmen Nass users and warrants further testing to accommodate cross-cultural differences in other populations.

This study investigated the human biomonitoring of heavy metals in the water, sediments, and tissues of mostly consumed fish species using Turkmen pregnant women's biomarkers in winter 2019, at the Miankaleh Peninsula, north of Iran. Metal concentrations were measured in various fish organs as well as pregnant women's blood, hair, and nail as biological indicators. For this purpose, a total of 20 water and sediment, 14 fish, and 16 human samples were collected. Inductively coupled plasma mass spectrometry (ICP-MS) was used to evaluate the concentration of Cr, Co, Cu, As, Hg, and Pb. Results showed metals with the highest concentrations as Cu and Cr in water (93.35 and 80.91 µg/l, respectively), Hg and Pb in sediment (7.40 µg/g for both), Cu and Pb in the liver (27.00 and 18.9 µg/g for C. carpio; 1414 and 31.7 µg/g for L. auratus), muscle (10.00 and 18.80 for C. carpio; 37.20 and 8.27 µg/g for L. auratus), and skin (26.40 and 9.90 for C. carpio; 10.80 and 11.74 µg/g for L. auratus). In addition, Cu, in pregnant women samples, had the highest values at 2.53 mg/l, 8.87, 36.46, and 29.04 µg/g for blood, hair, fingernail, and toenail, respectively. However, Co showed the lowest concentration in all studied samples. Fish liver and fingernail of pregnant women did reveal the highest heavy metal accumulation, whereas fish muscle and blood of pregnant women had the lowest accumulated heavy metals. The concentration of Hg in water, sediment, fish muscle, and women's blood and hair exceeded the limits suggested by various organizations. Therefore, this study highlighted that heavy metal concentration, in particular Hg, in water, sediments, and fish is a serious risk to the health of local inhabitants who rely on fisheries products and recommended that necessary information should be provided to warn Turkmen pregnant women in consumption of Hg-contaminated fish in this area.

INTRODUCTION: Hookah smoking has grown considerably among Iranian Turkmen in the past two decades. The reasons for this increase in the consumption of hookah are unclear. Therefore, this study was conducted with the aim of determining the factors related to the start of hookah smoking in men with Turkmen ethnicity. METHODS: This qualitative study was conducted between February 2018 and June 2018 in Turkmen cities of Golestan provinces in Iran. The study participants included 26 male Turkmen water pipe smokers with various ages, occupation, and education level. Study data were collected through semi-structured individual interview and the results were analyzed in August 2018 by content analysis. Data management was done by software, MAXQDA version 10. RESULTS: In this study, 26 hookah smoker men with the age range of 20-45 years were interviewed. The age of the participants at the time of starting hookah consumption varied from 14 to 25 years. On the basis of qualitative data, the reasons for the start of hookah smoking in male Turkmen were classified into three main categories: (1) individual (curiosity and sense of adulthood, fewer perceived risks compared with other substances and hookah's sensory attractions); (2) interpersonal (hookah-smoking friends and consumption of hookah by family members); and (3) societal (blaming unemployed people in small neighborhoods, cultural influence, more social acceptance compared with other substances, and easy access to hookah). CONCLUSION: Individual, interpersonal, and societal factors play important role in the start of hookah smoking among male Turkmens. Developing health policies based on the above factors can be effective in adopting hookah prevention and control strategies. Moreover, future studies could be developed with the goal of discovering ways to solve the problem of unemployment and plan for developing recreational activities in this area to prevent initiation of hookah smoking especially among youth.

Gorgan (Iran) have been studied for HLA-A, -B, -C, -DRB1 and -DQB1 genes for the first time. They are Turkmen and originated in East Asia around Altai Mts; they originally spoke a Turk language classified within the Turkish-Oguz group. Peripheral blood samples were collected from Gorgan City (Iran) and HLA typed by standard methodology. HLA allele frequencies were compared with 7984 chromosomes of other World populations and it was shown existence of admixture of Siberian and Mediterranean HLA characters in this population, probably due to longlasting contact with Persians. Three new HLA extended haplotypes were found: A*01:01-B*35:01-DRB1*03:01-DQB1*02:01, A*30:01-B*13:01-DRB1*15:01-DQB1*02:01 and A*31:01-B*35:01-DRB1*15:01-DQB1*03:01. Gorgan (Iran) were most close to Chuvashians (Noth Caspian Sea, Russia) and Siberians, like Tuvinians, Mansi and Buryats in Neighbour Joining and Vista analyses. It is established a relationship of this population with Kurgan (Gorgan, Iran) archaeological mounds culture. However, their kinship with Scythians (2nd century BC) and Sarmatians (4th century AD) is obscure although both of them spoke a Persian language.

BACKGROUND: Cytochrome P450 2C9 (CYP450 2C9) has an important role in metabolic processes. Mutations in CYP450 2C9 genes may affect the catalytic activity of this enzyme. The aim of the present study is to assess the genetic polymorphisms of Cytochrome P450 (2C9) enzyme in Turkmen and Fars ethnic groups with type 2 diabetes compared with controls. METHODS: A total of 336 Turkmen and 336 Fars type 2 diabetic patients and 336 healthy Turkmen and Fars individuals were included in this study. Genomic DNA was extracted from whole blood samples and then the CYP2C9 genotyping was done using the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism technique. RESULTS: The CYP2C9*1, CYP2C9*2 and CYP2C9*3 allele frequencies in type 2 diabetic patients were 85.27%, 11.68%, and 3.05%, and in control were 87.13%, 8.56%, and 4.31%, respectively. We found significant differences between allele distribution of 2C9 in type 2 diabetic patients and controls. CYP2C9*2 and CYP2C9*3 allele frequency was significantly different in Turkmen and Fars type 2 diabetic compared to two ethnic controls. The CYP2C9*1/*1 and CYP2C9*1/*2 genotypes frequencies in type 2 diabetic Turkmen showed significant differences compared to Turkmen control. There were significant differences in the genotype frequency of CYP2C9*1/*1, CYP2C9*1/*2, CYP2C9*1/*3, CYP2C9*2/*2, and CYP2C9*2/*3 between type 2 diabetic Fars and Fars controls. Two diabetic ethnic groups showed statistically significant differences in frequencies of CYP2C9*2/*2 and CYP2C9*2/*3 genotypes. CONCLUSION: Our study suggests that diabetic patients with mutant CYP2C9 polymorphism may show different antidiabetic drug metabolism compared to the wild-type allele. In this regard, determination of CYP2C9 alleles and genotypes can be a useful tool for the treatment of diabetic patients with antidiabetic drugs because it may assist physicians' to determine optimal dosage and efficiency of drugs metabolized by this polymorphic enzyme.

INTRODUCTION: Nass is a smokeless tobacco product. Iranian Turkmen have a long history of nass consumption. However, the factors contributing to nass consumption among Iranian Turkmen are not known. The purpose of the present study is to examine the factors contributing to nass consumption among Iranian Turkmen. METHODS: This qualitative study was conducted between January and March 2016 in four Turkmen cities of Golestan province in Iran. Participants included 34 male Turkmen nass consumers. Data were collected through individual and group interviews and were analyzed by content analysis. Data management was done by qualitative data analysis software MAXQDA, Version 10. RESULTS: The results of data analysis revealed the following as the main reasons for nass consumption by the study population: 1) cultural, social, and environmental facilitators, 2) nass was considered as an alternative to cigarette smoking, 3) nass was believed to intensify the effects of opium and other drugs, 4) specific occupations and circumstances, and 5) beliefs related to nass. CONCLUSIONS: Cultural and historical backgrounds, convenient access to nass at a very low price, curiosity, emulation, and peer pressure were the main factors driving nass consumption among Iranian Turkmen. Various beliefs, such as the idea that nass intensifies the effects of opium and alcohol, calms the nerves, and helps individuals quit smoking were also found to contribute to this phenomenon. Finally, individuals in certain lines of work, such as fishing, driving combines, and military service, were more likely to consume nass.
RESUMO
INTRODUCTION: It has been estimated that the metabolic syndrome may predict cardiovascular disease and the occurrence of sudden death, independent of the presence of other cardiovascular risk factors. The aim of the present study was to assess the metabolic syndrome among Turkmen women in this area. MATERIAL AND METHODS: The present study consisted of 160 Turkmen women. Baseline data and prevalence of metabolic syndrome and the components of metabolic syndrome in Turkmen women were determined. OBSERVATIONS AND RESULTS: The prevalence of high levels of fasting glucose, low levels of high density lipoprotein-cholesterol, high triglyceride levels, high waist circumference and high blood pressure were shown to be 29.37%, 70.62%, 35.62%, 75% and 26.25%, respectively. It was shown that high waist circumference (75%) and Low HDL-cholesterol levels (70.62%) were the most frequent characteristics in comparison to other metabolic components. The prevalence of high waist circumference, high triglyceride levels, high levels of fasting glucose, high blood pressure and BMIs which were ≥25 were higher in subjects with metabolic syndrome (92.85%, 73.21%, 73.21%, 57.14% and 83.92%, respectively). CONCLUSION: Metabolic syndrome is more prevalent among Turkmen women. Our data has shown that the prevalence of abnormal waist circumference in this ethnic group was highest. The waist circumference can be used as a predictor for cardiovascular disease and coronary heart disease.
