    Full Text Available Backgrounds: Genus Trichostrongylus (Nematoda: Trichostrongylidae is one of the most impor­tant zoonotic nematodes with wide geographic distribution in the world. The purpose of the present study was to describe morphological and morphometrical characteristics of male Trichostrongylus species, currently prevalent in domestic ruminants of Khuzestan Province, south­west Iran.Methods: Gastro-intestinal organs of 1600 sheep, goats, cattle, and buffalos, slaughtered in Khuzestan Province, southwest Iran, were examined for infectivity with Trichostrongylus spe­cies. For examination and measurements of helminthes, Azo-carmine staining was per­formed, followed by camera lucida drawings of morphological characters and measurements of morphometrical criteria with a calibrated microscope. Using valid nematodes systematic keys, almost all the parasites were identified at the level of species.Results: Overall, 114 animals were found infected with at least one species of Trichostrongy­lus. Considering morphological characteristics of male Trichostrongylus, six species were identi­fied including T. colubriformis, T. vitrinus, T. probolorus, T. capricola, T. longispicu­laris and Trichostrongylus sp. Conclusion: Although, compared to the previous decades, currently Trichostrongylus is much less prevalent in the domestic ruminants of the study area, but still different species occur in these animals.

    Full Text Available Objective: To determine possible parasitic arthropods fauna in certain rodent species in the west of Khuzestan Province including Ahvaz and its suburb and suburb of Hovizeh, southwest of Iran. Methods: In the current study Sherman live traps were used to catch the rodents. The rodents were identified using Iranian keys of rodents. The ectoparasites were picked up in different ways from bodies of the anesthetized rodents and stored in 70% ethanol to preserve and identified using international keys. Results: In the present study 3 species and 4 genera of ectoparasites and 4 species of rodents were identified. Conclusions: It is important to explain that the great ectoparasite biodiversity in the west of Khuzestan, with small sampling of rodents, described a high risk factor to transmit the different infectious diseases among domestic animals and humans.

    Arid regions of the world occupy up to 35% of the earth's surface, the basis of various definitions of climatic conditions, vegetation types or potential for food production. Due to their high ecological value, monitoring of arid regions is necessary and modern vegetation studies can help in the conservation and management of these areas. The use of remote sensing for mapping of desert vegetation is difficult due to mixing of the spectral reflectance of bright desert soils with the weak spectral response of sparse vegetation. We studied the vegetation types in the semiarid to arid region of Mond Protected Area, south-west Iran, based on unsupervised classification of the Spot XS bands and then produced updated maps. Sixteen map units covering 12 vegetation types were recognized in the area based on both field works and satellite mapping. Halocnemum strobilaceum and Suaeda fruticosa vegetation types were the dominant types and Ephedra foliata, Salicornia europaea-Suaeda heterophylla vegetation types were the smallest. Vegetation coverage decreased sharply with the increase in salinity towards the coastal areas of the Persian Gulf. The highest vegetation coverage belonged to the riparian vegetation along the Mond River, which represents the northern boundary of the protected area. The location of vegetation types was studied on the separate soil and habitat diversity maps of the study area, which helped in final refinements of the vegetation map produced.

    Rural health houses constitute a major provider of some primary health services in the villages of Iran. Given the challenges of providing health services in rural areas, health houses should be established based on the criteria of health network systems (HNSs). The value of these criteria and their precedence over others have not yet been thoroughly investigated. The present study was conducted to propose a model for improving the distribution of rural health houses in HNSs. The present applied study was conducted in Khuzestan province in the southwest of Iran in 2014-2016. First, the descriptive and spatial data required were collected and entered into ArcGIS after modifications, and the Geodatabase was then created. Based on the criteria of the HNS and according to experts' opinions, the main criteria and the sub-criteria for an optimal site selection were determined. To determine the criteria's coefficient of importance (ie, their weight), the main criteria and the sub-criteria were compared in pairs according to experts' opinions. The results of the pairwise comparisons were entered into Expert Choice and the weight of the main criteria and the sub-criteria were determined using the analytic hierarchy process (AHP). The application layers were then formed in geographic information system (GIS). A model was ultimately proposed in the GIS for the optimal distribution of rural health houses by overlaying the weighting layers and the other layers related to villages and rural health houses. Based on the experts' opinions, six criteria were determined as the main criteria for an optimal site selection for rural health houses, including welfare infrastructures, population, dispersion, accessibility, corresponding routes, distance to the rural health center and the absence of natural barriers to accessibility. Of the main criteria proposed, the highest weight was given to "population" (0.506). The priorities suggested in the proposed model for establishing rural

    Full Text Available Glucose-6-phosphate dehydrogenase (G6PD deficiency is one of the most common hereditary enzymatic disorders in human, increases the vulnerability of erythrocytes to oxidative stress. It is also characterized by remarkable molecular and biochemical heterogeneity. According to previous investigations, G6PD Cosenza (G1376C is a common G6PD mutation in some parts of Iran. Therefore in the present study we have characterized Cosenza mutation among G6PD deficient individuals in Khuzestan province. In order to identify G6PD Cosenza, we analyzed the G6PD gene in 64 samples out of 231 deficient individuals who had not G6PD Mediterranean mutation, using PCR- restriction fragment length polymorphism (RFLP method. G6PD Cosenza mutation was found in 6 males of 231 samples, resulting in the relative rate of 2.6% and allele frequency of 0.023 among Khuzestanian G6PD deficient subjects. A comparison of these results with previous findings in some parts of Iran suggests that G6PD Cosenza is a common mutation in Khuzestanian G6PD deficient individuals

    This study was designed and implemented to assess the current situation and to estimate the time trend of multiple sclerosis (MS), as well as to explain potential factors associated with such a trend. This longitudinal study was carried out based on analysis of the data from the monitoring and treatment surveillance system for 421 patients with MS in Kohgiluyeh and Boyer-Ahmad Province, Iran, from 1990 to 2015. To this end, curve estimation approach was used to investigate the changes in prevalence and incidence of the disease, and univariate time series model analysis was applied in order to estimate the disease incidence in the next 10 years. The mean and standard deviation of age were 29.78 and 8.5 years at the time of diagnosis, and the mean and 95% confidence interval of age were 29.18 (28.86-30.77) and 29.68 (28.06-31.30) at the time of diagnosis for women and men, respectively. The sex ratio (males to females) was estimated as 3.3, and the prevalence of the disease was estimated as 60.14 in 100,000 people. The diagram of the 35-year trend of the disease indicated three distinct patterns with a tendency to increase in recent years. The prevalence and incidence trend of the disease in the study population is consistent with regional and global changes. Climatic and environmental factors such as extreme weather changes, dust particles, expansion of the application of new industrial materials, and regional wars with potential use of banned weapons are among the issues that may, in part, be able to justify the global and regional changes of the disease. Predictive models indicate a growing trend of the disease, highlighting the need for more regular monitoring of the disease trend in upcoming years.

    Full Text Available Background and Objectives: Diabetes mellitus is among the most common causes of mortality in the world and an important risk factor for chronic kidney disease, foot amputation, ischemic heart disease and blindness among older adults. Diabetic patients mostly develop hyperlipidemia, which can result in cardiovascular diseases. Patient’s knowledge, attitude and practices toward diet are the core center for diabetes control and affect their metabolic control and complications. In the present study, we measured nutritional knowledge, attitude and practices and their relations to serum lipids, HbA1C, and fasting blood glucose in diabetic patients of Boirahmad County, southwest of Iran, where many people encounter increasing prevalence of diabetes. Materials and Methods: 198 IDDM patients from the rural and urban areas of Boirahmad County were invited to the health centers to be checked for their fasting blood glucose, serum total cholesterol, serum HDL cholesterol, serum triglyceride and also serum glycosylated hemoglobin. Their knowledge, attitude, and practices toward the diabetic diet were assessed using a validated questionnaire. The obtained scores were classified into three categories (Poor, average, and Good to show their knowledge, attitude and practice levels, and the serum parameters were compared between the levels to show the relevancies. Results: Our data showed that the patients’ knowledge and attitude on diabetic nutrition are mostly at the average level (79.3% and 47.1%, respectively but their practice scores are mostly at the poor level (43.8%, and just a minor proportion of the patients are at the appropriate levels (15.3, 33, and 23.1% of knowledge, attitude and practices, respectively. In addition, we found a significant reverse relationship between the patients’ nutritional knowledge and  serum HbA1C (p=0.003, and also between their attitude and serum triglyceride (p<0.05.

    Full Text Available Introduction: Iran and its aged society are facing some issues that significantly impact the current social structures in Iran. It will continue to do so on their growing as elderly with negative impacts on communal relations and unjust distribution of resources based on a gender basis that will affect the aging in place (AiP. The study aims to investigate the AiP within aged people and modifying role of the gender variables within it. Methods: This study describes the current AiP of the aged people in Ahwaz city in the southwest Iran from a gender perspective. The population available for the study was citizens 60 years of age and older (N=51594 in Ahwaz city. Sampling method was cluster-ratio based on municipal zones, ethnicity, and gender with sample size 382 (195 male and 187 female. The data were analysed by descriptive statistics, F-test and geographical information system. Results: Economically poor situation of the aged samples especially aged women, and their health status was moderated by low quality of nutrition and high prevalence of chronic conditions. For example, Arabs, Persian and Lor received low mean scores of 59.41, (SD= 7.332, 58.09 (SD= 11.963, and 57.02, (SD= 7.963 respectively in the health status. AiP characteristics are poor and discrimination was especially significantly prominent among elderly females. Multiple regression were found to modify AiP at the first step. The GLM reported that gender-ethnic discrimination directly affected AiP and high prevalent amongst elderly minority females. Conclusion: The current urban environment, in the southwest Iran, seems is unable to meet healthy needs of aged people. It needs to adjust upon gender and other relevant characteristics to monitor equality of outcomes for aged and minorities. The future research needs to focus on effect of ethnicity and gender-related issues on AiP, especially in developing countries like Iran. sure activities and mental health, provides evidence for

    SummarySeveral studies have indicated that consanguineous marriages (unions between biologically related persons) are associated with increased risk of autosomal recessive diseases and several multifactorial traits. Mandaeans are a closed ethno-religious community living in areas of southern Iraq and Iran (Khuzestan Province). There are currently no data on the prevalence of consanguineous marriages among Mandaeans. The present study was carried out in 2016 to determine the prevalence of consanguinity among Iranian Mandaeans living in Khuzestan Province, south-west Iran. A total of 137 couples (urban areas: 79 couples; rural areas: 58 couples) were included in the study. Information on the consanguineous marriages of the subjects was collected through direct interviews. Marriages were classified by the degree of relationship between couples as double first cousins, first cousins, first cousin once removed, second cousins and unrelated marriages. The coefficient of inbreeding (F) was calculated for each couple and the mean coefficient of inbreeding (α) estimated for the population, stratified by rural and urban areas. The overall frequency of consanguinity was found to be 50.7% in urban and 86.2% in rural areas. There was a significant difference between rural and urban areas in types of marriages (χ 2=24.8, df=4, p<0.001) and first cousin marriages (51.8%) were the most common type. The overall α-value was estimated to be 0.0363 for the Iranian Mandaean population.

    Trichinellosis is an important helminthic food-borne zoonosis, which is caused by nematodes of the genus Trichinella. Although, Trichinella spp. has been detected frequently in Iranian wildlife, this parasitic infection is not considered a major public health problem. This is largely because Islamic codes forbid consumption of pork meat in this country. However, knowledge about this zoonotic pathogen is important because human trichinellosis has been documented in countries where most of the population is Muslim. The aims of the present work were to investigate whether Trichinella spp. was still circulating in wildlife of the Khuzestan Province (south-west Iran) about 30 years after the first investigation, to identify the aetiological agent at the species level by molecular analyses, and to review the literature on Trichinella spp. in animals of Iran. During the winter 2009-2010, muscle samples from 32 road-killed animals (14 dogs and 18 jackals, Canis aureus) were collected. Muscle samples were digested and Trichinella sp. larvae were isolated from two jackals. The Trichinella sp. larvae have been identified as Trichinella britovi by molecular analyses. These results confirm that T. britovi is the prevalent species circulating in wild animals of Iran.

    Full Text Available Background: CVDs are the first cause of death globally. About 50% of annual deaths are related to this group of diseases in Iran; however, the economic cost of CVD on Iranian society has not been conducted. Objectives: The aim of this study was to estimate the economic burden of CVDs in the southwest of Iran in 2016 from the social perspective. Materials and Methods: This study is a cross-sectional descriptive-analytic study conducted using the cost of illness (COI framework. The prevalence top-down method was used to quantify the annual cardiovascular costs. Productivity losses were estimated using the human capital approach and the friction cost method, with the discount rate of 3% to convert all future lifetime earnings into the present value. Results: In 2016, the average total cost per patient was $1881.4 and the total costs resulted in 1159.62 $million. Direct costs accounted for 60% and indirect costs for 40% of the total costs. The results were robust to a 20% change in the average unit price of all medical and non- medical direct costs and to discount rate of 2% and 10%. Conclusions: The total cardiovascular disease costs in 2016 represented approximately 6.7% of the Iran gross domestic product. The results of this study would be of special help for policymakers to evaluate the cost-effectiveness and outcomes of health care programs to allocate health care resources efficiently. Primordial Prevention of CVD including lifestyle modifications and dietary interventions resulted in substantial financial savings and is strongly recommended.

Methods & Materials: This study was a descriptive-analytic survey that included 165 elderly in the urban areas of Iran`s Markazi province. Data were obtained via a general questionnaire and three 24-hours recalls. Results: The mean of overall HEI-2005 was 54.08. Ninty-three point three percent (93.3% of subjects consumed grains, 70.9% fruits, 84.2% whole fruit, 47.9% vegetables, 12.7% dark-orange vegetables and legumes, 37% dairy products, 40% meats, 18.8% oils, 40% saturated fats, 1.8% sodium and 1.2% discretionary calories (from solid fat and added sugar in optimal levels. Besides, none of the elderly people had a sufficient intake of whole grains. The HEI-2005 total score enhanced along with the increases in education level (P<0.05, income (P<0.01 and TV watching time (P<0.05. But, age and the HEI-2005 total score had an inverse relationship (P<0.001. Conclusion: Because the diet quality of elderly people in the urban areas of Iran`s Markazi province is low, they will benefit from the improvement of their diet quality. Also, they need to increase intakes of whole grains, dark-orange vegetables and legumes and plant oils, and reduce intakes of sodium and their energy levels from saturated fat and simple sugar. It should be pointed out that the government can help with the achievement of these objectives through some plans such as promoting their literacy level, income and nutritional knowledge.

    Iran is frequently affected by dust events because it is located in arid and semiarid belt of the world. As Khozestan province is in the vicinity of large deserts and also due to especial atmospheric conditions the frequency of dust in this area is increased in the recent years. Therefore it has the destructive affect on the healthcare, economy, social and etc. The study is based on the, sea level, 850 mb and 500 mb weather charts, surface wind field and observations weather data during the period of 1968-2008. By numerical simulation with WRF modeling it has tried to high light provide an answer to how this event produced and reached to Ahwaz. It has been shown in this 40 years, dust events by high strength and frequency occur in July in Ahwaz. Synoptic patterns revealed that for making sever dust event Persian Gulf thermal trough extends to the north west of Iraq and European ridge extends over the Black sea and large part of the Turkey by passing waves of middle level Mediterranean trough from northwest of Iraq and east of Syria. Numerical simulation shows strong surface flow over source regions in northwest of Iraq and east of Syria, creation westerly low level jet in low-lying areas and the increase in friction velocity in the source regions. In the deserts of Iraq and north east of Syria increase in friction velocity to its highest value (approx 0.6 m/s) causes reduction in visibility and by decrease to lowest value (approx 0.4 m/s) visibility reaches up to 600 meters in Ahwaz.

    The ideas of geological heritage and geological diversity have become very popular in the modern science. These are usually applied to geological domains or countries, provinces, districts, etc. Additionally, it appears to be sensible to assess heritage value of geological bodies. The review of the available knowledge and the field investigation of the Gachsaran Formation (lower Miocene) in southwest Iran permit to assign its features and the relevant phenomena to as much as 10 geological heritage types, namely stratigraphical, sedimentary, palaeontological, palaeogeographical, geomorphological, hydrogeological, engineering, structural, economical, and geohistorical types. The outstanding diversity of the features of this formation determines its high heritage value and the national rank. The geological heritage of the Gachsaran Formation is important to scientists, educators, and tourists. The Papoon and Abolhaiat sections of this formation are potential geological heritage sites, although these do not represent all above-mentioned types. The large territory, where the Gachsaran Formation outcrop, has a significant geoconservation and geotourism potential, and further inventory of geosites on this territory is necessary. Similar studies of geological bodies in North Africa and the Middle East can facilitate better understanding of the geological heritage of this vast territory.

    The most underdiagnosed water-borne bacterial zoonosis in the world is Leptospirosis which especially impacts tropical and humid regions. According to World Health Organization (WHO), the number of human cases is not known precisely. Available reports showed that worldwide incidences vary from 0.1-1 per 100 000 per year in temperate climates to 10-100 per 100 000 in the humid tropics. Pathogenic bacteria that is spread by the urines of rats is the main reason of water and soil infections. Rice field farmers who are in contact with infected water or soil, contain the most burden of leptospirosis prevalence. In recent years, this zoonotic disease have been occurred in north of Iran endemically. Guilan as the second rice production province (average=750 000 000 Kg, 40% of country production) after Mazandaran, has one of the most rural population (Male=487 679, Female=496 022) and rice workers (47 621 insured workers) among Iran provinces. The main objectives of this study were to analyse yearly spatial distribution and the possible spatial clusters of leptospirosis to better understand epidemiological aspects of them in the province. Survey was performed during the period of 2009-2013 at rural district level throughout the study area. Global clustering methods including the average nearest neighbour distance, Moran's I and General G indices were utilized to investigate the annual spatial distribution of diseases. At the end, significant spatial clusters have been detected with the objective of informing priority areas for public health planning and resource allocation.

    Kurdistan Province, with an area of 28,203 square kilometers, is located in a mountainous area in the western part of Iran. From 1967 to 1997, the urban population in the major eight cities of the Kurdistan Province-namely, Baneh, Bijar, Divan Darreh, Saghez, Sanandaj, Ghorveh, Kamyaran, and Marivan-increased from 102,250 to 705,715. The proportion of the population residing in urban areas increased 90 percent during this period. In most of the cities, solid waste handling remains primitive, and well-organized procedures for it have not been established. Traditional methods of disposal, with marginal inclusion of modern conveniences, appear to be the common practice. In general, the shortcomings of the prevailing practices can be summarized as follows: The municipal solid waste management systems (MSWMSs) in this province include unsegregated collection and open dumping of municipal solid wastes. Separation of municipal solid waste in this province is in the hands of scavengers. The MSWMSs in this province lack essential infrastructure. Thus, design and implementation of modern MSWMSs in this province are essential. Principal criteria for and methods of implementing these systems are as follows: (1) rationally evaluating all functional elements so that they operate in a steady-state or equilibrium manner; (2) creating all support elements for the MSWMS in each city; (3) introducing gradual privatization of MSWMS activities; (4) creating guidelines, regulations, and instructions for all elements of MSWMSs; and (5) giving priorities to source separation and recycling programs. This paper reviews the present status of MSWMSs in eight major cities of Kurdistan Province and outlines the principle guidelines and alternatives for MSWMSs.

    BACKGROUND The alarming incidence of self- burning provoked to set up a multidisciplinary preventive program to decrease the incidence and complications of this harmful issue. This study investigated the incidence and the preventive measures in self-burn in Fars Province, southern Iran. METHODS This study was a longitudinal prospective design on trend of self-inflicted burn injuries in Fars province after setting up a regional multidisciplinary preventive plan (2009-2012). RESULTS From 18862 admitted patients, 388 (2%) committed self-burning. While the incidence showed a constant decrease in proportion of suicidal cases among all admitted patients (2.5% to 1.6%). The mean age of self-burning victims ranged from 28.3±10.8 to 30.3±11.7 years. The female victims comprised 67.4% of all suicidal burn patients (Female to male ratio: 2.18). The leading causes of suicide commitment were familial conflicts (75.6%) and psychological problems (16.7%) CONCLUSION It is crucial to continue the regional preventive programs and pave the way to set up national, and even international collaborations to alleviate relevant financial, social, cultural and infrastructural difficulties in order to have lower incidence for this dramatic issue.

The aim of this study was to investigate some important factors affecting uplanned pregnancies among married women in Semnan province, one of the developed provinces of Iran with below replacement fertility level. Methods: The data for this study were drawn from a cross-sectional survey conducted in Semnan province in 2014. A total of 363 married women within the age range of 15-49 years who were pregnant or had the history of at least one delivery were considered. The study sample was selected using multi-stage stratified sampling method. The data were collected using a self-structured questionnaire with 90 items and Cronbach's alpha coefficient of 0.88. Data analysis was performed in SPSS (version 20 using Crammer’s V coefficients and Chi-square tests. Logistic regression analysis was also applied to model the risk of unintended pregnancies based on selected covariates. Results: According to the results, around 18.2% of the pregnancies were unplanned, 7.7% and 10.5% of which were mistimed and unwanted, respectively. Based on the logistic regression analysis, birth cohort, number of children ever born, and contraceptive methods had significant effects on the risk of unintended pregnancies. Furthermore, about 48% of the women experiencing unintended pregnancy were using a traditional contraceptive method before or at the time of the conception.   Conclusion: As the findings indicated, the women who used contraceptive method, as well as those with higher number of children and younger birth cohorts had higher risk of unplanned pregnancies. It should be noted that the majority of unplanned pregnancies among the women in younger birth cohort were mistimed pregnancies. So it is recommended to continue offering

    Large Igneous Provinces (LIPs) are important features of the Earth history especially recognized during Paleo to Mezosoic times when they are related to the break up of supercontinents (Coffin and Eldhom, 1994). These provinces occur in several different tectonic settings such as volcanic passive margins, submarine ridges and continental and oceanic plateaux. Mafic-dominanted provinces are the most well known among the LIPs and the best examples are the Karoo, Kerguelem and Ontong-Java. LIPs including an important silicic component have been described in some basaltic provinces of southern Africa (Milner et al. 1992). More recently, silicic-dominated LIPs have been recognized in eastern Australia (Bryan et al., 2000), in southern South America (Pankhurst et al. 1998) and in Antartica Penninsula (Riley and Leat, 1999). The common characteristics of this kind of LIP include: 1) large volume of silicic rocks with dominance of ignimbrites, 2) active over 40 to 50 m.y.; and 3) spatially and temporally associated with plate break up. In this paper we present the main geologic and geochronologic characteristics of the Teles Pires volcanic province from southwest Amazon Craton, which allow its classification as a Paleoprotorozoic silicic-dominated LIP. Geologic implications of this suggestion includes the existence of a large cratonic plate as old as 1.81Ga for the Amazon Craton, therefore the proposed 1.85-1.55 Ga magmatic arc of Rio Negro-Juruena Province should be reviewed (au)

    Full Text Available Background: The purpose of this study was to perform seroepidemiological investigation for determining the status of human fasciolosis in Pirabad Village, Lorestan Province, western Iran. Methods: Blood samples were taken from residents of the village including 801 individuals. Sera were separated and stored at -20°C until used. The samples were analyzed using ELISA. Results: Anti-Fasciola antibodies were detected in 6 (0.7% individuals. Difference between age, sex and drinking or swimming in the surface water with seropositivity to fasciolosis was not significant. Out of 7 shepherds, 1 (14.3% was seropositive. Due to the small number of shepherds, comprehensive statistical inference in this regard cannot be done. Significant difference was detected between seropositivity to fasciolosis and consuming local freshwater vegetables during the last 6 months (P=0.001.Conclusion: Metacercariae carrying local freshwater plants might be the main source of contamination because consumption of these kinds of vegetables was confirmed by all participants. Awareness of local communities regarding the danger of freshwater plant consumption, through health education programs, will decrease the risk of infection.

    Full Text Available Linguatula serrata is one of the important zoonotic parasites. Carnivores serve as definitive host. The larvae existed in mesenteric lymph nodes (MLNs, liver, lungs, etc of intermediate herbivores. The definitive host becomes infected by ingesting viscera containing the infective nymphal stage. Humans may be infected with Linguatula either by ingestion of nymphs resulting in a condition called nasopharyngeal linguatulosis or Halzoun syndrome or by ingestionof infective eggs which develop in internal organs resulting in visceral linguatulosis. Indian crested porcupine (Hystrix indica is a common rodent in Middle East. Based on some tradition, consumption of Histrix meat andviscera is common in some parts of Iran. The present study reports the occurrence of Linguatula serrata nymph in H. indica as a new intermediate host from southwest of Iran.

Patients and Methods In this descriptive study, 209 nurses (census sampling method from 6 educational hospitals in East Azerbaijan Province were participated. The attitude of nurses was investigated with Euthanasia Attitude Questionnaire, which is a 31-item scale. This scale investigate the attitude of nurses in 5 domains, including general attitude (3 items, legal and religious issues (5 items, end of life care (8 items, euthanasia decision making (8 items, and attitude toward different types of euthanasia (7 items. Descriptive statistics were used for data analysis using SPSS software (ver. 13. Results Participants had a negative attitude towards all aspects of euthanasia. They reported that they would not participate in euthanasia procedure even this procedure was accepted by religious leaders and legal authorities. They believed that caring of end of life patients is a burden but this is not a reason for euthanasia and also they did not consider patients or their relative as decision makers for euthanasia. In addition, participants rejected all types of euthanasia. Conclusions Iranian nurses in East Azerbaijan Provence have negative attitudes toward different aspects of euthanasia and this negative attitude is not related to religious or legal issues. So, searching for the reasons for such an attitude needs more investigation.

    Full Text Available Introduction: Congenital hypothyroidism (CH is one of the most common preventable causes of mental retardation. Its worldwide incidence is estimated to be one in 2500-5500 births. Assessment of thyroid gland in neonates is critical. The aims of this study were to demonstrate the incidence of CH in neonates born in Yazd province, Iran in 1389 (2010 and compare the results with other reported studies and investigate biochemical characteristics of affected infants. Materials & Methods: This is an analytical descriptive cross-sectional study. The study was conducted on all infants (13022 births born in 1389 (March 2010-March 2011. Thyroid stimulating hormone (TSH was measured using ELISA technique. Results: Forty five infants suffered from congenital hypothyroidism with an overall incidence of one in 289 live births. Twenty five of the diagnosed infants were males (incidence 1:261 and twenty were females (incidence 1:325. The incidence of CH in boys was more than girls (P-value = 0.295. The highest incidence of CH was observed in spring followed by summer and the lowest incidence was in autumn followed by winter (P-value=0.000. Conclusion: The CH incidence was 10.3 to 13.8 times more than other countries. The highest CH incidence was in spring followed by summer and the lowest incidence was in autumn followed by winter. It is important that a larger size of cases need to be screened and more information on the aetiology of the affected infants to be obtained

    In Iran, leptospirosis is endemic to Caspian Sea littoral. The disease appears as a seasonal infection mostly affecting people in rural areas involved in farming. We investigated the prevalence of this infection among suspected patients in Gilan Province by an indirect immunofluorescent assay (IFA), and two PCR protocols, a nested-PCR and a real-time PCR (qPCR), targeting rrs and lipL32 genes, respectively. We also identified the common Leptospira species by sequencing a partial sequence of rrs gene. Out of the 128 sera examined by IFA, 25.78% were positive with the antibody titers ≥1/80. The antibody titer in 39.06% of sera ranged from 1/10 to 1/140, and 35. 16% showed no antibodies, all considered negative. Nested PCR and qPCR detected Leptospira DNA in 20.31% and 18.75% of the sera, respectively. The two PCR assays had 98.43% agreement (K = 0.93) and showed an inverse correlation with the IFA titers. Also, three pathogenic Leptospira species, L. kirschneri (n = 10), L. introgans (n = 8), and L. borgpetersenii (n = 2) were identified from the clinical specimens in the study area. In our hands both PCR assays proved very efficient for early diagnosis of illness and could be used in combination with IFA for both diagnosis and epidemiological studies, but nested PCR was cheaper and appeared more appropriate for our laboratories in rural settings.

    The incidence and mortality rates of cancer are increasing worldwide, particularly in the developing countries. Valid data are needed for measuring the cancer burden and making appropriate decisions toward cancer control. We evaluated the completeness of death registry with regard to cancer death in Fars Province, I. R. of Iran. We used data from three sources in Fars Province, including the national death registry (source 1), the follow-up data from the pathology-based cancer registry (source 2) and hospital based records (source 3) during 2004 - 2006. We used the capture-recapture method and estimated underestimation and the true age standardized mortality rate (ASMR) for cancer. We used log-linear (LL) modeling for statistical analysis. We observed 1941, 480, and 355 cancer deaths in sources 1, 2 and 3, respectively. After data linkage, we estimated that mortality registry had about 40% underestimation for cancer death. After adjustment for this underestimation rate, the ASMR of cancer in the Fars Province for all cancer types increased from 44.8 per 100,000 (95% CI: 42.8 - 46.7) to 76.3 per 100,000 (95% CI: 73.3 - 78.9), accounting for 3309 (95% CI: 3151 - 3293) cancer deaths annually. The mortality rate of cancer is considerably higher than the rates reported by the routine registry in Iran. Improvement in the validity and completeness of the mortality registry is needed to estimate the true mortality rate caused by cancer in Iran.

    Full Text Available Objective: To identify sero-prevalence of brucellosis among blood donors in Ahvaz city, Southwest Iran. Methods: A total number of 1 450 serum samples from blood donation were collected and were screened for the presence of brucella antibody. Rose Bengal Plate Test, Standard Agglutination Test (SAT, and 2-mercaptoethanol (2ME agglutination were tested in the sample. SAT dilution ≥1/80 and 2ME agglutination ≥1/40 were considered positive. Results: Sero-prevalence of brucellosis among the blood donors was 0.70%, 0.34%, and 0.20% by Rose Bengal Plate Test, SAT, and 2ME respectively. Conclusions: Considering the 1/80 titer of SAT as the criteria of contamination with brucella, routine screening of sero-prevalence of brucella in blood donors is not recommended in this area.

    The aim of this study was to measure income-related inequality in completed suicide across the provinces of Iran. This ecological study was performed using data from the Urban and Rural Household Income and Expenditure Survey-2010 conducted by the Iranian Center of Statistics, along with data on completed suicide from the Iranian Legal Medicine Organization in 2012. We calculated the Gini coefficient of per capita income and the completed suicide rate, as well as the concentration index for per capita income inequality in completed suicide, across the provinces of Iran. The Gini coefficients of per capita income and the completed suicide rate in the provinces of Iran were 0.10 (95% confidence interval [CI], 0.06 to 0.13) and 0.34 (95% CI, 0.21 to 0.46), respectively. We found a trivial decreasing trend in the completed suicide incidence rate according to income quintile. The poorest-to-richest ratio in the completed suicide rate was 2.01 (95% CI, 1.26 to 3.22). The concentration index of completed suicide in the provinces of Iran was -0.12 (95% CI, -0.30 to 0.06). This study found that lower income might be considered as a risk factor for completed suicide. Nonetheless, further individual studies incorporating multivariable analysis and repeated cross-sectional data would allow a more fine-grained analysis of this phenomenon.

    Background: Various regions in Iran, especially the Khuzestan Province, have been covered by dust and dirt during the past two years due to environmental changes in the Middle East. We sought to evaluate the effect of these pollutants on the coagulant factors of people residing in Abadan and Khoramshahr, two major cities of Khuzestan Province. Methods: One hundred twenty-nine healthy individuals were enrolled into this study, and their prothrombin time as well as fibrinogen, platelet, and Factor VIII levels were measured before and after climate changes. Results: After climate changes, the mean prothrombin time decreased, while the fibrinogen, platelet, and Factor VIII levels rose. Conclusion: The results of this study suggest that the pollutants deployed in the Middle East can affect prothrombin time as well as fibrinogen, platelet, and Factor VII levels considerably and increase coagulant state. The pollutants can, consequently, increase the risk of cardiovascular diseases. It seems that cooperation at government levels between Iran and its neighboring countries is required to reverse desertification and avoid inaccurate usage of subterranean water resources so as to lessen air pollution.

    The production of genetically modified (GM) crops is growing around the world, and with it possible opportunities to combat food insecurity and hunger, as well as solutions to current problems facing conventional agriculture. In this regard the use of GMOs in food and agricultural applications has increased greatly over the past decade. However, the development of GM crops has been a matter of considerable interest and worldwide public controversy. This, in addition to skepticism, has stifled the use of this practice on a large scale in many areas, including Iran. It stands to reason that a greater understanding of this practice could be formed after a review of the existing expert opinions surrounding GM crops. Therefore, the purpose of this study was to analyze the predictors that influence agricultural experts' attitudes toward the development of and policies related to GM crops. Using a descriptive correlational research method, questionnaire data was collected from 65 experts from the Agricultural Organization in the Gotvand district in Southwest Iran. Results indicated that agricultural experts were aware of the environmental benefits and possible risks associated with GM crops. The majority of participants agreed that GM crops could improve food security and accelerate rural development, and were proponents of labeling practices for GM crops. Finally, there was a positive correlation between the perception of benefits and attitudes towards GM crops.

    Full Text Available Agrobiodiversity is an issue that has been considered for the last decade. There are few reports on diversity of orchard species in Iran and some available reports have not mentioned the relevant indices and analysis results. In the current study, based upon data collected from 29 provinces of Iran along with 23 counties of Khorasan provinces, a comprehensive analysis was made and different diversity indices such as Shanon- Weaver, Evenness index, Margalof richness index as well as two dominance indices including Sympson and Berger-Parker were calculated. The results indicated that Kerman, Fars and Khorasan provinces cover 40% of orchard areas in the country. Species richness in all provinces was relatively high but the evenness index was not so (average evenness for all provinces is 0.55. Therefore, in some provinces such as Boshehr and Kerman, species dominance is observed due to Date and Pistachio, respectively. Also, Stone fruits among Khorasan orchards provided the highest richness and diversity. The highest area of orchards in Khorasan are belonged to nuts including Pistachio, Almond, Walnut and Oleaster. Kashmar district has the highest orchards area in Khorasan province. According to the Shanon-Weaver index, the highest and lowest diversity were observed at Nahbandan- Birjand and Fariman counties. Results also indicated that the Berger-Parker dominance index is highest at Fariman and Shirvan districts of Khorasan because of apple and grape species dominance.

    Based on the related published papers, and by using Geographic Information System (ArcGIS 9.3), this paper analyzed the species composition and geographical distribution of threatened fishes in Yunnan Province of Southwest China. There were 83 threatened species living in the Province, belonging to 5 orders, 13 families, and 47 genera. Cypriniformes was absolutely dominant, with 64 species, followed by Siluriformes, with 16 species. Cyprinidae fishes had 51 species, accounting for 79.7% of Cypriniformes. The most species of Cyprinid fishes were of Barbinae (14 species), Cyprininae (10 species), and Cultrinae (10 species). The threatened fishes could be divided into two zoogeographical regions, i. e., Tibetan Plateau region and Oriental region, and their species composition and geographical distribution were resulted from the historical evolution adapted to the related environments. Whatever in rivers and in lakes, the Cyprinid fishes were both absolutely dominant, occupying 36.1% and 31.3% of the total, respectively. The Cyprinid fishes in rivers were mostly of endangered species, while those in lakes were mostly of vulnerable species. The factors affecting the threatened fishes in the Province were discussed from the two aspects of geodynamic evolution and present situation.

    Full Text Available 【Abstract】Objective: To identify the main character-istics of victims of motorcycle accidents in Fars Province, Iran. Methods: This cross-sectional study was conducted in Fars Province which has the fourth largest population of all 31 provinces in Iran from March 2009 to June 2010. We included data from all 542 recorded cases of fatalities due to motor vehicle accidents. Data were recorded from the foren-sic medicine registry consisting of demographic and acci-dent-related information. Demographic information con-sisted of name, age, sex, status of fatal victim (motorcycle driver vs passenger and educational level. Results: Of the 2 345 autopsy records from the foren-sic medicine archives, 542 (23.1% gave the cause of death as motor vehicle accidents. Mean age of these victims was (31.4±16.5 years, and the male to female ratio was 28. Head injury was the most common cause of death in these victims, and overall they tended to have a low level of education. Motorcycle accidents frequently involved younger age groups (15-35 years, and head trauma related with non-use of a helmet was the most common cause of death. Conclusions: Head injury is frequent among victims in the province we studied. This situation may be related to the victims’ low socioeconomic status and little education regarding traffic laws leading to speeding and disregard of these laws along with their weak enforcement.

    Suicide is a major cause of unnatural deaths in the world. Its incidence is higher in western provinces of Iran. So far, there has not been any time series analysis of suicide in western provinces. The purpose of this study was to analyze suicide mortality data from 2006 to 2016 as well as to forecast the number of suicides for 2017 in four provinces of Iran (Ilam, Kermanshah and Lorestan and Kohgiluyeh and Boyer-Ahmad). Descriptive-analytic study. Data were analyzed by time- series analysis using R software. Three automatic methods (Auto.arima, ETS (Error Transitional Seasonality) and time series linear model (TSLM)) were fitted on the data. The best model after cross validation according to the mean absolute error measure was selected for forecasting. Totally, 7004 suicidal deaths occurred of which, 4259 were male and 2745 were female. The mean age of the study population was (32.05 ± 15.48 yr). Hanging and self-immolation were the most frequent types of suicide in men and women, respectively. The maximum and minimum number of suicides was occurred in July and August as well as January respectively. It is suggested that intervention measures should be designed in order to decrease the suicide rate particularly in the age group of 15-29 yr, and implemented as a pilot study, especially in these four provinces of Iran, which have a relatively high suicide rate.

    Full Text Available Toxoplasma gondii is an important foodborne protozoan that can be transmitted through infected blood containing tachyzoite form of the parasite. The current study aimed to evaluate the prevalence of T. gondii infection and related risk factors among healthy blood donors in Boyer-Ahmad County, southwest Iran. Blood samples were taken from 285 healthy blood donors who voluntarily agreed to participate in this study. Sera and buffy coat were isolated from the blood samples for serological and molecular evaluations. The sera were tested for anti-T. gondii antibodies (both IgG and IgM, using a commercial ELISA kit. The buffy coat of seropositive cases was evaluated for detection of T. gondii DNA by PCR. Moreover, a structured questionnaire, containing socioepidemiological data and possible risk factors, was filled out by each participant during sample collection. Anti-T. gondii antibodies were detected in sera of 48/285 (16.8% participants. Only two of the subjects (0.7% were seropositive for both IgG and IgM antibodies. T. gondii DNA was not detected in buffy coat of any of the seropositive cases. Risk factors such as contact with soil (OR, 9.7; 95% CI, 4.9–19.4 and consumption of semicooked meat (OR, 2.5; 95% CI, 1.2–5.03 were statistically associated with seropositivity to T. gondii. The seroprevalence rate of T. gondii antibodies in the blood donors of Boyer-Ahmad County was not high in comparison with other regions in Iran. In this study, consumption of undercooked meats, job, and contact with soil were independent risk factors associated with T. gondii infection, which can be considered as potential sources of T. gondii infection.

    Equine piroplasmosis (EP) is the cause of persistent tick-borne infection with no symptoms, but the most important problem of EP is due to the persistent carrier state. Carrier animals to Babesia (Theileria) equi (Laveran 1901) and B. caballi (Nuttall, 1910) infestation could be identified by extremely sensitive PCR-based method. The purpose of this study was to identify the causative agents of equine piroplasmosis based on molecular and microscopic assays in equids from Kurdistan Province, Iran. Thirty one horse and mule blood samples were used with history of living in Kurdistan Province of Iran. The blood specimens were utilized for T. equi and B. caballi DNA identification by PCR and Giemsa stained smears for microscopic observation. The results clearly showed the presence of B. (Theileria) equi DNA in 30 of 31 blood samples (96.77%), but the microscopic examination revealed the 3 of 31 positive Babesia like organisms in the red blood cells (9.67%). The obtained results demonstrated the presence of hidden B. (Theileria) equi infection in horses with previous habitance in Kurdistan Province of Iran. The carrier animals became a main source of infection and can transmit the disease. Therefore, hidden infection might be considered as a health threatening and limiting factor in animals used in therapeutic antisera research and production centers.

    Full Text Available This survey study aimed at identifying the factors influencing the success of animal husbandry cooperatives in Southwest Iran. Using a questionnaire, the data were collected from 95 managing directors of the cooperatives who were chosen through a multi-stage stratified random sampling method. This study showed an essential need for a systemic framework to analyze the cooperatives’ success. The results showed that the “Honey Bee”, “Cattle (dairy”, and “Lamb” cooperatives were the most successful among different kinds of the cooperatives. Also, among individual attributes, “interest”, “technical knowledge”, and “understanding the concept of cooperative”; among economic variables, “income” and “current investment”; and among external factors, “market access” have significant correlation with the success while structural variables have no significant relation. Furthermore, among all the factors, four variables (“interest”, “understanding the concept of cooperative”, “market access”, and “other incomes” can explain the variations of the success.

    Organisms that have been genetically engineered and modified (GM) are referred to as genetically modified organisms (GMOs). Bt crops are plants that have been genetically modified to produce certain proteins from the soil bacteria Bacillus thuringiensis (Bt), which makes these plants resistant to certain lepidopteran and coleopteran species. Genetically Modified (GM) rice was produced in 2006 by Iranian researchers from Tarom Mowla'ii and has since been called 'Bt rice'. As rice is an important source of food for over 3 billion inhabitants on Earth, this study aims to use a correlational survey in order to shed light on the predicting factors relating to the extent of stakeholders' behavioral intentions towards Bt rice. It is assumed and the results confirm that "attitudes toward GM crops" can be used as a bridge in the Attitude Model and the Behavioral Intention Model in order to establish an integrated model. To this end, a case study was made of the Southwest part of Iran in order to verify this research model. This study also revealed that as a part of the integrated research framework in the Behavior Intention Model both constructs of attitude and the subjective norm of the respondents serve as the predicting factors of stakeholders' intentions of working with Bt rice. In addition, the Attitude Model, as the other part of the integrated research framework, showed that the stakeholders' attitudes toward Bt rice can only be determined by the perceived benefits (e.g. positive outcomes) of Bt rice.

    Considering the importance of Balikhlou River as one of the most important water sources of Ardabil, Nir and Sarein cities, maintaining water quality of this river is the most important goals in provincial and national levels. This river includes a wide area that provides agricultural, industrial and drinking water for the residents. Thus, surveying the quality of this river is important in planning and managing of region. This study examined the quality of river through eight physicochemical parameters (SO4, No3, BOD5, TDS, turbidity, pH, EC, COD) in two high- and low-water seasons by international and national standards in 2013. For this purpose, a review along the river has been done in five stations using t test and SPSS software. Model results showed that the amount difference in TDS and EC with WHO standards, and TDS rates with Iran standards in low-water seasons, pH and EC with WHO standards in high-water seasons, is not significant in high-water season; but for pH and SO4 parameters, turbidity and NO3 in both standards and EC value with WHO standard in low-water season and pH, EC, SO4 parameters and turbidity and NO3 in high-water season have significant difference from 5 to 1%, this shows the ideal limit and lowness of parameters for different usage.

    ABSTRACT: Iran plate is prone to earthquake, occurrence of destructive earthquakes approximately every 5 years certify it. Due to existence of happened great earthquakes and large number of potential seismic sources (active faults) which some of them are responsible for great earthquakes the North-West of Iran which is located in junction of Alborz and Zagros seismotectonic provinces (Mirzaii et al, 1998) is an interesting area for seismologists. Considering to population and existence of large cities like Tabriz, Ardabil and Orumiyeh which play crucial role in industry and economy of Iran, authors decided to focus on study of seismic hazard assessment in these two provinces to achieve ground acceleration in different frequency content and indicate critical frequencies in the studied area. It is important to note that however lots of studies have been done in North -West of Iran, but building code modifications also need frequency content analysis to asses seismic hazard more precisely which has been done in the present study. Furthermore, in previous studies have been applied free download softwares which were provided before 2000 but the most important advantage of this study is applying professional industrial software which has been written in 2009 and provided by authors. This applied software can cover previous software weak points very well such as gridding potential sources, attention to the seismogenic zone and applying attenuation relationships directly. Obtained hazard maps illustrate that maximum accelerations will be experienced in North West to South East direction which increased by frequency reduction from 100 Hz to 10 Hz then decreased by frequency reduce (to 0.25 Hz). Maximum acceleration will be occurred in the basement in 10 HZ frequency content. Keywords: hazard map, Frequency content, seismogenic zone, Iran

    To determine the epidemiological characteristics of fatal traffic accidents in Fars province, Iran. This cross-sectional study included 3642 traffic accident deaths in Fars province, Iran between November 2009 and November 2011. The data source was the Fars Forensic Medicine Registry, which covers the entire province. According to Iranian law, all deaths resulting from injuries or accidents must be investigated to determine the exact cause of death by autopsy. All such deaths are referred to forensic medicine centres in each city, and all data are sent to the main centre in Shiraz, the capital city of Fars province. Males accounted for 78.3% of the decedents (sex ratio of almost 3.6:1), and the mean ± standard deviation age of all decedents was 32.2 ± 20.3 years. Autopsy reports indicated that head trauma was the most common cause of death. Most collisions were vehicle-vehicle crashes (52.3%), with cars and motorcycles being the most prevalent modes of transport (39.6% and 24.6%, respectively). Fatal accidents were most common during the summer. Most fatal injuries (61.4%) occurred on outer-city roads and 27.4% occurred on inner-city roads. Significant associations were found between decedent's status (car driver, motorcycle driver or passenger, pedestrian or passenger) and interval between injury and death, light conditions at the scene of the accident, place of death, site of injury and cause of death. Although the clinical management of trauma patients has improved in Iran, coordination between trauma system organizations is required to decrease the burden of injuries.

    Lele Ren

    Full Text Available Reconstructing ancient diets and the use of animals and plants augment our understanding of how humans adapted to different environments. Yunnan Province in southwest China is ecologically and environmentally diverse. During the Neolithic and Bronze Age periods, this region was occupied by a variety of local culture groups with diverse subsistence systems and material culture. In this paper, we obtained carbon (δ13C and nitrogen (δ15N isotopic ratios from human and faunal remains in order to reconstruct human paleodiets and strategies for animal exploitation at the Bronze Age site of Shilinggang (ca. 2500 Cal BP in northwest Yunnan Province. The δ13C results for human samples from Shilinggang demonstrate that people's diets were mainly dominated by C3-based foodstuffs, probably due to both direct consumption of C3 food and as a result of C3 foddering of consumed animals. Auxiliary C4 food signals can also be detected. High δ15N values indicate that meat was an important component of the diet. Analysis of faunal samples indicates that people primarily fed pigs and dogs with human food waste, while sheep/goats and cattle were foddered with other food sources. We compare stable isotope and archaeobotanical data from Shilinggang with data from other Bronze Age sites in Yunnan to explore potential regional variation in subsistence strategies. Our work suggests that people adopted different animal utilization and subsistence strategies in different parts of Yunnan during the Bronze Age period, probably as local adaptations to the highly diversified and isolated environments in the region.

    Full Text Available Background: The aim of this study was the seroepidemiological survey for detecting the status of human fasciolosis in Lorestan Province, western Iran.Methods: This cross-sectional study was conducted in 2015-16. Based on statistical estimations, 1256 serum samples were collected from different parts of Lorestan Province, western Iran, and stored at -20 °C until use. The collected serum samples were analyzed at Tehran University of Medical Sciences, Tehran, Iran using indirect ELISA method.Results: Anti-Fasciola antibodies were detected in 16 (1.3% individuals. Regarding the seropositivity to fasciolosis, no significant differences were found between age groups, sex, level of education and occupation; however significant differences were observed regarding location, consuming local freshwater plants and water resources (P<0.02.Conclusion: Local freshwater plants and unfiltered water resources were probably the main sources of the infection. Health education by local health centers to elevate awareness of people, and providing facilities for safer drinking water, especially in rural areas may help decrease the risk of fasciolosis infection in this region.

    After the detection of arsenic (As) toxicity in sheep from Ebrahim-abad and Babanazar villages in Kurdistan province, the concentration of this element in drinking water, cultivated soil, alfalfa hay, wool, and blood samples was evaluated. Total As concentrations ranged from 119 to 310 μg/L in drinking water, 46.70-819.20 mg/kg in soil 1.90-6.90 mg/kg in vegetation 1.56-10.79 mg/kg in sheep's wool, and 86.30-656 μg/L in blood samples. These very high As contents, in all parts of the biogeochemical cycle, exceed the recommended normal range for this element compared with a control area. Results indicate that As has moved through all compartments of the biogeochemical cycle by way of direct or indirect pathways. The present investigation illustrated decreased packed cell volume and hemoglobin in sheep from the As-contaminated zone. It was concluded that sheep from the contaminated areas suffer from anemia. Chronic As exposure of the liver was determined by liver function tests. For this purpose, blood aspartate transaminase (AST) and alanine transaminase (ALT) were measured. The results show that serum ALT and AST activities are increased significantly (p < 0.01) in the sheep population exposed to As in the contaminated zone. Moreover, chronic As exposure causes injury to hepatocytes and damages the liver.

    The Pabdeh-Lali Anticline of northern Khuzestan province is located in southwestern Iran and occupies 790 km2. This structure is situated in the Zagros folded belt. As a result of well-developed karst systems in the anticlinal axis, the water supply potential is high and is drained by many peripheral springs. However, there is a scarcity of water for agriculture and population centers on the anticlinal flanks, which imposes a severe problem in terms of area development. This study combines remotely sensed (RS) data and a geographical information system (GIS) into a RSGIS technique to delineate new areas for groundwater development and specific sites for drilling productive water wells. Toward these goals, RS data were used to develop GIS layers for lithology, structural geology, topographic slope, elevation, and drainage density. Field measurements were made to create spring-location and groundwater-quality GIS layers. Subsequently, expert choice and relational methods were used in a GIS environment to conjunctively analyze all layers to delineate preferable regions and 43 individual sites in which to drill water wells. Results indicate that the most preferred areas are, in preferential order, within recent alluvial deposits, the Bakhtiyari Conglomerates, and the Aghajari Sandstone. The Asmari Limestone and other units have much lower potential for groundwater supplies. Potential usefulness of the RSGIS method was indicated when six out of nine producing wells recently drilled by the Khozestan Water and Power Authority (which had no knowledge of this study) were located in areas preferentially selected by this technique.

    This study aims to identify the effect of activation processes of Indonesian zeolite from Southwest Aceh District, Aceh Province on the physical characteristics and chemical contents changes. The work was conducted by downsizing of natural zeolite into nano particle size, treating it physically (heated up to 105˚C) and chemically (soaked with 0.5 M HCl for 1 hour), and finally calcining it at the temperature of 350° C for 2 hours. The natural and activated nano zeolites were then characterized by using SEM, BET, XRD, XRF and FTIR in order to examine their characters and chemical contents. The characterization results showed that the activated nano zeolite has better appearances than the natural one. The XRD analysis showed that the main minerals of zeolite are quartz and calcite clinochlore. Further, the XRF analysis showed that there are elements of magnesium, calcium and potassium which can be as a cation exchange with other metal elements. Based on the identified properties, this zeolite showed a good performance to be used as an adsorbent in waste water treatment process, especially after activated.

    Results of the first stable isotopes analysis (δ""1"3C and δ"1"5N) of archaeological sites located in the southwest of the province of Buenos Aires (Argentina) are presented. Both the construction of an isotopic ecology and prehistoric human diets of the sector are explored. The isotopic ecology indicates diverse environments in which marine animals have enriched δ"1"3C col. values; while terrestrial species such as coypo, greater rhea and large-sized herbivores have the poorest values that are indistinguishable among the different taxa. Furthermore, ducks and a hairy armadillo showed intermediate values. Human isotopic values indicate a diet based on the consumption of meat. These proteins came predominantly from terrestrial animals complemented by marine resources. The local archaeological record is consistent with this information, as the main faunal resources are terrestrial species; nevertheless a scarce representation of marine fauna, mainly Otariids, is registered. In this paper we present the first isotopic values for the studied area and thus it is a preliminary contribution that must be further investigated with new samples

    Full Text Available This study was conducted to determine the prevalence of Brucella canis antibodies in different breeds, sex and ages of dogs in southern of Iran. A total of 113 whole blood samples were taken from different breeds based on exotic or native sources. The samples were examined with immunochromatography assay for detection of B. canis antibodies. Twelve dogs were serologically positive (10.62%. There was significant differences in ratio of infected dogs between breeds (exotic or native, ages (less, equal or more than 2 years old and the history of vaccination (against rabies, leptospirosis, parvovirus, adenovirus type 2, canine distemper, parainfluenza (P<0.001. However, the results were not significant statistically, among both sex (P=0.058 and the history of clinical signs (P=0.456 in seropositive dogs. Based on this study and the other investigation in companion dogs from southwest of Iran, it seems that the mixed and spray (native breeds are not infected with B. canis, yet. Conversely, the exotic breeds would be the source of bacterium in Iran. Therefore, preventive and control measures are strongly recommended.

    Given that the there is little information about the current status of brucellosis and Q fever in most parts of Iran, the aim of this study was to assay the seroprevalence of these two diseases in high-risk populations of Kurdistan Province in western Iran. Two hundred fifty sera samples were collected from hunters and their families, butchers, health care workers, and those referred to medical diagnostic laboratories in the southwestern regions of Kurdistan Province. Sera were tested to detect specific immunoglobulin G (IgG) antibodies against brucellosis and Coxiella burnetii (phase I and II). The seroprevalence of brucellosis and Q fever (C. burnetii IgG phase I and II) was 6.4% and 27.83% (20% and 14.52%), respectively. The highest seroprevalence of Q fever (38%) and brucellosis (12%) was seen in butchers, who handled cattle, sheep, and goats during their work. Age had a significant positive association with Q fever seropositivity (p=0.04). The seroprevalence of Q fever was higher in those people who had been in employment for more than 10 years (21.88%) compared to others (7.79%) (p=0.02). The keeping of animals (p=0.03), hunting and eating the meat of wild animals (p=0.02), and not disinfecting hands and faces after working (for health care workers and butchers) (p=0.02) were risk factors for Q fever seropositivity. This study showed a relatively high seroprevalence of brucellosis and Q fever in high-risk populations of Kurdistan Province. It is suggested that complementary studies be carried out in other parts of western Iran to clarify the epidemiological aspects of these diseases.

    This article is devoted to application of a simulation algorithm based on geostatistical methods to compile and update seismotectonic provinces in which Iran has been chosen as a case study. Traditionally, tectonic maps together with seismological data and information (e.g., earthquake catalogues, earthquake mechanism, and microseismic data) have been used to update seismotectonic provinces. In many cases, incomplete earthquake catalogues are one of the important challenges in this procedure. To overcome this problem, a geostatistical simulation algorithm, turning band simulation, TBSIM, was applied to make a synthetic data to improve incomplete earthquake catalogues. Then, the synthetic data was added to the traditional information to study the seismicity homogeneity and classify the areas according to tectonic and seismic properties to update seismotectonic provinces. In this paper, (i) different magnitude types in the studied catalogues have been homogenized to moment magnitude (Mw), and earthquake declustering was then carried out to remove aftershocks and foreshocks; (ii) time normalization method was introduced to decrease the uncertainty in a temporal domain prior to start the simulation procedure; (iii) variography has been carried out in each subregion to study spatial regressions (e.g., west-southwestern area showed a spatial regression from 0.4 to 1.4 decimal degrees; the maximum range identified in the azimuth of 135 ± 10); (iv) TBSIM algorithm was then applied to make simulated events which gave rise to make 68,800 synthetic events according to the spatial regression found in several directions; (v) simulated events (i.e., magnitudes) were classified based on their intensity in ArcGIS packages and homogenous seismic zones have been determined. Finally, according to the synthetic data, tectonic features, and actual earthquake catalogues, 17 seismotectonic provinces were introduced in four major classes introduced as very high, high, moderate, and low

    Leishmania infantum is the principal agent of visceral leishmaniosis (kala-azar) in all areas of Iran. The disease is endemic in Fars, Ardabil, East Azerbaijan and Bushehr provinces while it is sporadic in other parts of the country. Dog as a member of canidae family is the main animal reservoir host of kala-azar. The present study was carried out to determine the sero-prevalence of canine leishmaniosis in Mashhad, the capital city of Khorasan Razavi Province, in the north east of Iran. Two-hundred and nine dogs in two different classes including stray and sheepdogs were selected for this cross-sectional study. The blood samples were collected and tested by indirect immunofluorescent antibody test for detection of anti-Leishmania infantum antibodies. The results showed that 16/209 (7.6 %) of blood samples were positive. The sero-prevalence rates in stray and sheepdogs were 11/94 (11.7 %) and 5/115 (4.3 %), respectively (p < 0.05). Based on the results obtained, it is concluded that visceral leishmaniosis is distributed among dogs of this area, also sero-prevalence of canine leishmaniosis in stray dogs higher than sheepdogs.

    Few studies have focused on syndromic data to determine levels of alarm thresholds to detection of meningitis outbreaks. The purpose of this study was to determine threshold levels of meningitis outbreak in Hamadan Province, west of Iran. Data on both confirmed and suspected cases of meningitis (fever and neurological symptom) form 21 March 2010 to 20 March 2012 were used in Hamadan Province, Iran. Alarm threshold levels of meningitis outbreak were determined using four different methods including absolute values or standard method, relative increase, statistical cutoff points and upper control limit of exponentially weighted moving average (EWMA) algorithm. Among 723 reported cases, 41 were diagnosed to have meningitis. Standard level of alarm thresholds for meningitis outbreak was determined as incidence of 5/100000 persons. Increasing 1.5 to two times in reported cases of suspected meningitis per week was known as the threshold levels according to relative increase method. An occurrence four cases of suspected meningitis per week that equals to 90th percentile was chosen as alarm thresholds by statistical cut off point method. The corresponding value according to EWMA algorithm was 2.57 i.e. three cases. Policy makers and staff of syndromic surveillance systems are highly recommended to apply the above different methods to determine the levels of alarm threshold.

This study sought to determine the trend of maternal mortality ratio (MMR and its associated factors in Khorasan Razavi province, Iran. Methods: This retrospective cross-sectional study was conducted in Khorasan Razavi Province, North East of Iran, during 2010 to 2014. Data was collected from the reports of Maternal Mortality Committee of Mashhad University of Medical Sciences, Mashhad, Iran. The MMR was calculated for each period, and its trend was estimated. Chi-square test was used to find the relationship between mode of delivery and direct or indirect causes of maternal death. Results: According to the results, 94 maternal deaths occurred during 2010 to 2014. The total MMR was 17.68 (95%CI: 13.59-21.77 per 100,000 live births. The mean maternal age was 30.7±6.1 years old. Most of the deaths (75.6% occurred during postpartum period, from which 81% happened following a high-risk pregnancy. In addition, 50% of the mothers had proper numbers of visits during pregnancy. The most direct and indirect causes of maternal death were maternal hemorrhage (24.5% and cardiovascular diseases (12.8%, respectively. The relative risk of maternal mortality associated with cesarean section was 1.3 in comparison to normal vaginal delivery. Conclusion: The estimation of MMR is essential for decision-making and resource allocation. To reach this goal, a good registration system is needed to register all deaths and their exact causes.

    Full Text Available Rodents are mammals that comprise more than 2000 species and approximately 30 families. There are many morphological and ecological differences among them as variations in their shape, size, weight and habitat. In addition to significant economic losses, rodents have a major role in the dissemination of infectious diseases caused by viruses, bacteria, parasites or other micro-organisms. Rodents are important reservoirs of diseases which have been observed in many cities of Iran provinces especially along Caspian Sea border to Alborz Mountain. The aim of this study is to assess the geographical distribution of rodents in three provinces of northern part of Iran as reservoir of potential endemic infectious diseases. Rodents in 10 major parts of each of the three provinces of Mazandaran, Gilan and Golestan, northern Iran were collected and a total of 404 rodents were trapped alive. They were determined by the key characteristics such as gender, genus, species, different locations and topological situation. Statistical analysis was performed to characterize the study sample and to correlate all variables and parameters. The distribution frequencies of three, five and six genera of rodents were identified in Mazandaran, Gilan and Golestan provinces respectively. The overall distribution frequency of eight genera of rodents in the three provinces were identified as Rattus (R. norvegicus (67.3%, R. rattus (13.6%, Apodemus sylvaticus (13.9%, Arvicola (1%, Mus musculus (0.3%, Nesokia indica (2.5%, Cricetulus migrates (0.7% and Rhombomys opimus (0.7%.

    Full Text Available Background: Kermanshah province has one of the highest suicide rates in Iran. The aim of this study is to explore spatial variations in the relative risk of suicide across the counties of Kermanshah province. Methods: This is an applied ecological study in which county-level counts of suicide deaths recorded by the forensic medicine organization of Kermanshah province during the period March 21, 2006 to March 20, 2013 have been used. Following a Bayesian approach, Besag, York and Mollie's (BYM model was fitted to the number of suicide deaths of males, females and all persons to make inference about the relative risk of suicide across the counties of the province. Results: Over the study period and based on 95% credible intervals, Kangavar, Harsin and Sonqor counties had significantly lower relative risks of suicide for both males and females, Slas-Babajani, Paveh, Javanrud and Ravansar counties had significantly lower relative risks of suicide only for males and Kermanshah county had a significantly higher relative risk of suicide only for males. The relative risk of suicide for the other counties were not significantly different from the province’s overall risk neither for males nor females. Conclusion: The counties of Kermanshah province can be classified into four categories by the level of relative risk of suicide: low relative risk for both males and females, low relative risk only for males, high relative risk only for males and average relative risk. Findings from this study could be used to specify priority counties for suicide prevention initiatives.

    Full Text Available Sistan and Baluchestan Province spans five degrees latitude, with variations in natural phenomena, with cultural and historical resources and beautiful beaches in the south that have a great potential in attracting tourists. To investigate the relationship between climate and tourism, the climate index has been developed so that data are presented showing the individuals’ reactions to climate. The current study chose the tourist major cities of Iran and meteorological data was used to calculate the 20-year period up to 2012. In order to calculate the three climate indices (Predict Mean Vote - PMV, the Physiological Equivalent Temperature - PET and the Standard Effective Temperature - SET, RayMan software was used. These indices were then discussed and the spatial distribution of climatic comfort was represented in GIS environment. The most important national, religious, historical, and natural places in the province were presented and the climate calendar of tourism was identified. The results showed that tourism is concentrated in two periods, hot and cold. The cold period in southern cities such as Chabahar, Konarak and Sarbaz makes them tourist destinations, while the cities of Zahedan, Khash, Zabol, located at higher latitudes, are chosen tourist destination in spring and autumn. Summer has the highest thermal stress in the province.

    To isolate and identify Nocardia spp. from soil in different regions of Isfahan province in the center of Iran. This study was conducted in 32 districts (16 cities and 16 villages) in Isfahan province during two years. A total of 800 soil samples from these regions were studied by using kanamycin. The isolated Nocardia species were examined by gram and acid-fast staining and were identified biochemically and morphologically. The frequency and distribution of Nocardia spp. were determined in relation to different factors such as soil pH and temperate climate. From 153 (19.1%) Nocardia isolates identified, Nocardia asteroids (N. asteroids) complex (45.5%) and Nocardia brasiliensis (N. brasiliensis) (24.7%) were the most frequently isolated species, followed by Nocardia otitidiscaviarum (2.2%), Nocardiopsis dassonvillei, Actinomadura actinomadura (each 1.7%) and Nocardia transvalensis (1.1%) and also unknown spp. (23.0%). In this study, most species (54.4%) of Nocardia, especially N. asteroides complex were isolated from soils with pH: 7.01-8, whereas in pH: 8.01-9 more N. brasiliensis was isolated. The most Nocardia spp. was detected from regions with semi-nomadic and temperate climate (41.1%). N. asteroids complex is more prevalent in Isfahan province and soil can be a potential source of nocardiosis infections. It is to be considering that climate and soil pH are involved in the frequency and diversity of aerobic Actinomycetes.

    Cutaneous Leishmaniasis (CL) is one of the main neglected vector-borne diseases in the Middle East, including Iran. This study aimed to map the spatial distribution and species composition of sand flies in Hormozgan Province and to predict the best ecological niches for main CL vectors in this area. A database that included all earlier studies on sand flies in Hormozgan Province was established. Sand flies were also collected from some localities across the province. Prediction maps for main vectors were developed using MaxEnt model. A total of 27 sand fly species were reported from the study area. Phlebotomus papatasi Scopoli, Phlebotomus sergenti s.l. Parrot, Phlebotomus alexandri Sinton, Sergentomyia sintoni Pringle, Sergentomyia clydei Sinton, Sergentomyia tiberiadis Adler, and Sergentomyia baghdadis Adler (Diptera: Psychodidae) had the widest distribution range. The probability of their presence as the main vectors of CL was calculated to be 0.0003-0.9410 and 0.0031-0.8880 for P. papatasi and P. sergenti s.l., respectively. The best ecological niches for P. papatasi were found in the central south, southeast, and a narrow area in southwest, whereas central south to northern area had better niches for P. sergenti s.l. The endemic areas are in Bandar-e Jask, where transmission occurs, whereas in Bastak, the cases were imported from endemic foci of Fars province. In conclusion, proven and suspected vectors of CL and VL were recorded in this study. Due to the existence of endemic foci of CL, and favorite ecological niches for its vectors, there is potential risk of emerging CL in new areas.

    Full Text Available Background: Visceral leishmaniasis (VL or kala-azar is a parasitic disease caused by the species of Leishmania donovani complex. It is endemic in some parts of provinces of Iran. According to the reported cases of VL in Kermanshah Province in recent years, this study was conducted to determine the seroprevalence of VL in high risk villages of the province.Metods: Totally, 1622 serum samples obtained from children under 15 years old and 178 from adults in 22 villages of studied areas. Serum samples were examined by direct agglutination test (DAT for the detection of anti-Leishmania antibodies. Data were analyzed using SPSS software ver.11.5.Results: Only 6 serum samples (0.33% showed anti-Leishmania antibodies against L.infantum at titers ≥ 1/3200. Four of the seropositive cases had a history of kala-azar and Leishman bodies were seen in their bone marrows. The highest (0.5% and lowest (0.29% seroprevalence was seen in the age groups of 5-9 and 10-14 years old, respectively. None of the adults were seropositive. There were not any significant differences be­tween the rate of seropositivity in males (0.36% and females (0.31%. 66.7% of seropositive individuals showed clinical manifestations. The most important symptoms in Kala-azar patients were fever, hepato-spleenome­gally and anemia.Conclusion: Kala-azar is occurred sporadically in Kermanshah Province. But presence of significant number of positive sera confirms the necessity for attention of people and clinicians to kala-azar.

    Full Text Available Background:    Salmonellosis is an infectious and a food-borne disease of humans and animals. The initial source of the infection is the intestinal tracts of birds and other animals. Apparently healthy animals can become subclinical carriers and persistently shed Salmonella in their feces which can act as a reservoir for the pathogen. The aim of this study is to detect the carriers of Salmonella among apparently healthy sheep and goat flocks of Bushehr and Lorestan provinces, Iran.Methods:    A total of 389 fecal samples were aseptically collected from the rectum of apparently healthy sheep and goat flocks of Bushehr and Lorestan provinces. Bacteriological culture was conducted using selenite cystine, Rappaport–Vassiliadis, brilliant green and xylose lysine deoxycholate agar. Suspected colonies were inoculated in to TSI, peptone water, Simmon’s Citrate, Urea medium and MRVP. Sero-groups were detected by antisera.              Results:    Two samples from 189 samples (1.05% were positive for Salmonella in Bushehr province. Salmonella abortusovis and Salmonella typhimurium were detected following serotyping. No Salmonella carriers were detected in Lorestan province.Conclusion:    As the rate of carriers of Salmonella was low, the risk of food-borne salmonellosis due to consumption of small ruminant's meat is low, especially in the condition of well cooked meat. Since S. abortusovis was detected, strategies of prevention and control of abortion due to this agent must be taken to reduce the economic losses. Moreover, the presence of S. typhimurium is a hazard to public health and people who have close contact to sheep and goats.

    Full Text Available "nBackground: Pediculus capitis or head louse infestation affects millions of children worldwide, especially those in the 5-11 years age group. This study aimed to determine the prevalence of head pediculosis among school children in ur­ban and rural areas of Fars Province, southern Iran."nMethods: All school children of age 6-11 yr from both genders in all urban and rural areas of the province were screened for head louse infestation by examination of their hair and scalps. Parents of all infested children were also exam­ined. The study was repeated in different seasons in the same areas. Moreover, infested children were treated with 5% permethrin shampoo and re-examined one week later for any relapse."nResults: The general prevalence of head louse infestation in primary school students was 0.49% in autumn, 0.37% in win­ter and 0.20% in spring. In the mentioned seasons, the prevalence of P. capitis was higher among females and in ru­ral areas (P=0.001. Although treatment with permethrin shampoo failed in females, it was successful in all infected males from both regions in autumn and spring and in males from urban areas in winter."nConclusion: Head louse infestation is uncommon among Fars Province school children in rural and urban areas and should not be considered a public health priority. However, due to the higher prevalence of pediculosis in low socioeco­nomic group and rural area in our region, it seems that health promotion, particularly early detection and effec­tive management strategies should target this group in the province.

    The Bideghan area is located south of the Qom province (central of Iran). The most impressive geological features in the studied area are the Eocene sequences which are intruded by volcanic rocks with basic compositions. Advanced Space borne Thermal Emission and Reflection Radiometer (ASTER) image processing have been used for hydrothermal alteration mapping and lineaments identification in the investigated area. In this research false color composite, band ratio, Principal Component Analysis (PCA), Least Square Fit (LS-Fit) and Spectral Angel Mapping (SAM) techniques were applied on ASTER data and argillic, phyllic, Iron oxide and propylitic alteration zones were separated. Lineaments were identified by aid of false color composite, high pass filters and hill-shade DEM techniques. The results of this study demonstrate the usefulness of remote sensing method and ASTER multi-spectral data for alteration and lineament mapping. Finally, the results were confirmed by field investigation.

    Full Text Available Background: There are many reports on the association between anthracosis and tuberculosis. This study focuses on bronchial anthracosis and associated diseases in the province of South Khorasan-Iran. Methods: This case-series study is performed on patients referred to the Vali-e-Asre Hospital (South Khorasan-Iran for bronchoscopic evaluations during the period of 2009-2012. Written informed consents were obtained prior to bronchoscopic evaluations. The criterion for diagnosis of bronchial anthracosis was black pigmentation on direct observation of bronchus. Bronchial anthracosis was classified into simple (without deformity or complicated (with deformity. Pulmonary tuberculosis (TB was diagnosed either by acid fast staining and culture of liquid samples, or histopathology examination of biopsy. Spirometry was performed to determine the obstructive or restrictive pattern. Results: Among 279 patients who underwent bronchoscopic evaluations, 89 patients, including 34 males (38.2% and 55 (61.79% females, were diagnosed with anthracosis. Simple and complicated anthracosis were observed in 42 (48.2% and 47 (52.8% cases respectively. Mean age of patients was 72.23±9.65 years. There were 43 (48.3% cases of tuberculosis (28 cases with complicated and 15 cases with simple anthracosis (P=0.021.

    Hospital waste is considered dangerous because it may possess pathogenic agents and can cause undesirable effects on human health and the environment. In Iran, neither rules have been compiled nor does exact information exist regarding hospital waste management. The survey presented in this article was carried out in all 15 private hospitals of Fars province (Iran) from the total numbers of 50 governmental and private hospitals located in this province, in order to determine the amount of different kinds of waste produced and the present situation of waste management. The results indicated that the waste generation rate is 4.45 kg/bed/day, which includes 1830 kg (71.44%) of domestic waste, 712 kg (27.8%) of infectious waste, and 19.6 kg (0.76%) of sharps. Segregation of the different types of waste is not carried out perfectly. Two (13.3%) of the hospitals use containers without lids for on-site transport of wastes. Nine (60%) of the hospitals are equipped with an incinerator and six of them (40%) have operational problems with the incinerators. In all hospitals municipal workers transport waste outside the hospital premises daily or at the most on alternative days. In the hospitals under study, there aren't any training courses about hospital waste management and the hazards associated with them. The training courses that are provided are either ineffective or unsuitable. Performing extensive studies all over the country, compiling and enacting rules, establishing standards and providing effective personnel training are the main challenges for the concerned authorities and specialists in this field

    Full Text Available Introduction: Hanging is one of the most commonly used way to commit suicide in many countries. This method used in suicide is considered a problem in Iran too, but no clear data exists regarding hanging in different regions or the country as a whole. Because of the epidemiologic differences in non-judicial hanging in different regions, this study aimed to assess it in Gilan province, Iran between 2011 and 2013. Methods: In this cross-sectional study, profiles of hanging cases registered in Poorsina hospital in Gilan, Iran between 2011 and 2013 were evaluated. Age, sex, marital status, place of residency, level of education, occupation, history of suicide, history of clinical illness, season of suicide and hanging outcome were evaluated. Results: 59 cases of hanging (mean age 31.4 ± 13.1 years and 83.0% male were evaluated. 12 (20.34% suffered from psychological disorders, and 9 (15.2% confessed to substance abuse. 7 (11.9% had a history of suicide attempts by hanging. Hanging was significantly higher in men (p<0.001, people with an education level of less than high school diploma (p=0.02 and the unemployed (p<0.05 patients. In the end, 20 (33.9% of these attempts resulted in death. Conclusion: The results of this study showed that in 2 years, 59 cases committed suicide by hanging themselves, 33.9% of which finally died. Committing suicide by hanging was significantly more prevalent in men, people with an education level of less than high school diploma and the unemployed.

    Full Text Available Background Hepatitis B virus (HBV and hepatitis C virus (HCV infections are among the most occupational hazards in the world, including Iran. Barbers have continued to expose to different infectious diseases. They may often be exposed accidentally to the blood and body fluids of their customers, through needle pricks, scissor cuts, tattooing and other beauty treatments. Objectives The aim of the present study was to determine the seroprevalence of HBV, and HCV infections and to investigate the correlation between the HBs-Ab titer and some of the risk factors in the barbers of Isfahan city, Iran. Patients and Methods This cross-sectional seroepidemiological study was performed on 479 male and female barbers during July to September 2012 in Isfahan Province, Iran. Data were collected using a self-reporting questionnaire including demographic characteristics and main risk factors for HCV and HBV infections. A 5-mL venous blood sample was obtained from each subject. The levels of antigen and antibodies (HBs Ag, HBc Ab, HBs Ab, and HCV Ab were measured by the enzyme-linked immunosorbant assay (ELISA. Data were analyzed using descriptive statistics by SPSS software, version 16. Results The mean age of the individuals was 39.6 ± 11.4 years. Two hundred and thirty-three cases (48.6% were men and 246 (51.4% were women. All the subjects were negative for HCV Ab. The seropositivity of HBV was 6.6%. No significant correlation was found between risk factors and being HBV-seropositive. Among our participants, it was found that most barbers had been exposed to razors or scissor cuts. Conclusions Our findings indicate that both HCV and HBV infections may not constitute occupational hazards for barbers; however, it is essential to promote awareness of these risks among barbers and effective HBV vaccination should be performed among them.

    Wild olive (O. europaea ssp cuspidata) plants grow in various regions of Iran and are expected to have considerable genetic diversity due to adaptation to the various environmental conditions. We examined the genetic diversity of four populations of wild olive growing in Hormozgan Province located in southern Iran by using 30 RAPDs and 10 ISSR markers. The mean value of polymorphism for RAPD loci was 73.71%, while the value for ISSR loci was 81.74%. The Keshar population had the highest value of intra-population polymorphism for both RAPD and ISSR loci (66.86 and 62.71%, respectively), while the Tudar population had the lowest values (20.35 and 28.81%, respectively). Similarly, the highest and lowest number of effective alleles, Shannon index and Nei's genetic diversity were also found for these two populations. The highest value of H(pop)/H(sp) within population genetic diversity for RAPD and ISSR loci was found for the Keshar population (H(pop) = 0.85 and H(sp) = 0.90). OPA04-750, OPA13-650 and OPA02-350 RAPD bands were specific for Tudar, Bondon and Keshar populations, respectively, while no specific ISSR bands were observed. Analysis of molecular variance as well as the pairwise F(ST) test showed significant differences for RAPD and ISSR markers among the populations. The NJ and UPGMA trees also separated the wild olive populations from each other, indicating their genetic distinctness. UPGMA clustering of the four wild olive populations placed the Tudar population far from the other populations; Keshar and Bokhoon population samples revealed more similarity and were grouped together. We conclude that there is high genetic diversity among O. europaea ssp cuspidata populations located in southern Iran. We also found RAPD and ISSR markers to be useful molecular tools to discriminate and evaluate genetic variations in wild olive trees.

    Full Text Available Rotaviruses group A are the major cause of diarrhea in calves under one month and every year causes enormous economic losses. Serological and molecular techniques can be used for rapid detection of rotaviruses but virus isolation requires specific methods of cell culture and suitable cell lines. In this study, 41 samples were collected from diarrheal calves up to the age of one month, from industrial and semi-industrial farms in Tehran and Alborz provinces. The samples were positive by RT-PCR on VP6 gene. After preparation and inoculation onto MA104 cells in roller tube culture and constant cell culture system, the cytopathic effect (CPE was observed. Eligible cultured with CPE, were confirmed by two-step RT-PCR using VP6 gene primers. Semi-nested PCR using VP7 gene primers was also performed for G-genotyping in which 11 and 2 samples were detected as G6 and G10, respectively. This is the first report on isolation and identification of rotaviruses, one of the causative agents of viral diarrhea in Iran. The results of this research suggest that, these two types, can be used as the dominant strains for manufacturing a suitable vaccine against the rotaviruses in Iran.

    Cystic echinococcosis (CE) is a globally parasitic zoonosis caused by larval stages of Echinococcus granulosus. This study investigated E. granulosus genotypes isolated from livestock and humans in the Golestan province, northern Iran, southeast of the Caspian sea, using partial sequencing data of the cytochrome c oxidase subunit 1 (cox1) and NADH dehydrogenase 1 (nad1) mitochondrial genes. Seventy E. granulosus isolates were collected from animals in slaughterhouses: 18 isolates from sheep, 40 from cattle, nine from camels, two from buffaloes and one from a goat, along with four human isolates (formalin-fixed, paraffin-embedded tissues) from CE patients of provincial hospitals. All isolates were successfully analysed by PCR amplification and sequencing. The sequence analysis found four E. granulosus genotypes among the 74 CE isolates: G1 (78.3%), G2 (2.7%), G3 (15%) and G6 (4%). The G1-G3 complex genotype was found in all of the sheep, goat, cattle and buffalo isolates. Among the nine camel isolates, the frequency of G1-G3 and G6 genotypes were 66.7% and 33.3%, respectively. All four human CE isolates belonged to E. granulosus sensu stricto. This study reports the first occurrence of the G2 genotype in cattle from Iran and confirms the previously reported G3 genotype in camels in the same country. PMID:27253740

    Full Text Available Following human fascioliasis outbreaks in 1988 and 1999 in Gilan province, northern Iran, efforts are now made to shed light on the seasonal pattern of fascioliasis transmission in this endemic area, taking into account snail host populations, climatic conditions and human cases. Populations of the intermediate host snail (Lymnaea spp. peak in May and November, while there is a fourfold increase in the rate of human fascioliasis in February compared to that of September. Transmission is likely to occur mainly in late autumn and sporadically in late spring. Rainfall, seasonally analysed in periods of 3 years, indicates that accumulated summer rainfall may be related with the 1988 and 1999 human fascioliasis outbreaks. Although a more detailed picture, based on the analysis of further abiotic and biotic factors influencing fascioliasis transmission in this area, is required to substantiate this hypothesis, our results serve as the first step of a geographical information system project concerning the epidemiological study of fascioliasis in Iran. This local-scale study concerning the effects of climate change and natural disasters on the spread of fascioliasis aims to facilitate the understanding of what goes on at the regional scale in this respect.

    Rodents are an important source of zoonotic diseases for human. The aim of this study was to determine the infectivity of rodents with intestinal helminths in North Khorasan Province, Iran. One hundred and thirteen rodents were collected using different collection methods such as kill and live traps, digging of their burrow, filling of their hiding places with water and hand net during 2011-2013. Their alimentary canals were removed in the laboratory and helminths were determined in the department of parasitology, Tehran University of Medical Sciences. Thirteen species of helminths parasites were found in 13 species of rodents, including Aspiculuris tetraptera, Hymenolepis diminuta, Nippostrongylus brasiliensis, Protospirura Seurat, Rictolaria ratti, Skrjabinitaenia lobata, Streptopharagus kuntzi, Syphacia obvelata, Taenia taeniaeformis, Trichuris muris, Cysticercus fasciolaris, Acanthocephal. spp and Trichuris spp . Some of them were reported for the first time in new host in Iran. S. obvelata and A. tetraptera were the most frequent parasites and P. Seurat, R. ratti and C. fasciolaris were found only in one rodent. This is the first study to investigate the intestinal parasites in rodents in this area. Among different species identified, some of helminths were reported in new host.

    Feces of stray cat are potential sources of gastrointestinal parasites and play a crucial role in spreading and transmitting parasite eggs, larvae, and oocysts through contamination of soil, food, or water. In this study, we investigated the prevalence of Toxocara spp. infection in stray cats in Ahvaz city, southwest Iran. Eggs of Toxocara spp. in feces of stray cats were detected by the sucrose flotation method, and identification was conducted by polymerase chain reaction (PCR) and DNA sequencing. Of the 140 fecal samples that were randomly collected from public environments during the months of January to May 2012, 45% were found to harbour Toxocara spp. eggs. The highest prevalence of Toxocara spp. eggs was found in the central area of Ahvaz city (28.6%). T. canis eggs were found in 4 (6.34%) of the 63 positive samples. Stray cats are found in parks, playgrounds, and other public places and may be a potential contamination risk. Identification of Toxocara spp. using molecular methods is sufficiently sensitive to detect low levels of parasites and identify the different Toxocara spp. in feces. The relatively high prevalence of Toxocara spp. infection may continue to increase due to lack of effective environmental hygiene control in Iran. Consequently, there is a need to plan adequate programs to detect, identify, and control this infection as well as stray cats in the region.

    Considering that medical ethics is an applied subject providing systematic solutions to help physicians with moral issues, this research aimed to evaluate adherence to the principles of medical ethics among physicians on the basis of attitude of physicians of Mazandaran province. This cross-sectional study was conducted in Mazandaran province, Iran during 2015. A researcher-made questionnaire was used for data collection. The questionnaire was first completed by 40 physicians and its reliability was confirmed by obtaining a Cronbach's alpha coefficient equal to 0.818. Its validity was confirmed by medical ethics experts. Therefore, the questionnaire was reliable and valid. Analytical and descriptive analysis were performed. According to our findings, there is a significant correlation between some of variables of medical ethics principles. The results show that adherence to indicators of beneficence, non-maleficence and justice has been almost good; however, physicians' ethical behaviors which pertain towards the principle of autonomy have not been acceptable. There was not any significant difference in adherence to the principles of autonomy, beneficence and non-maleficence, and justice on the basis of sex, residency, education and occupation. According to the present study, more training is required to improve physicians' adherence to the principles of medical ethics . 2018 The Author(s).

    Mosquitoes are important vectors of human and animal diseases. This study updates current knowledge on fauna, dominance, and distribution of mosquitoes in Mazandaran Province, Northern Iran, to inform disease control effort. Larval collections, using standard dippers or droppers, and adult collections, using total catches, shelter pits, CDC light traps, and human landing catches, were performed monthly in 30 villages across 16 counties, from May to December 2014. Ovitraps, baited with hay infusion as oviposition attractants or stimulants for Aedes (Stegomyia) mosquitoes, were installed in each village and inspected weekly for eggs. Lactophenol and Berlese media were used for preserving and mounting specimens. Overall, 36,024 mosquito specimens (19,840 larvae and 16,184 adults) belonging to 4 genera and 20 species were morphologically identified. The dominance and distribution indices showed that Culex pipiens s.s. was the eudominant species with a constant distribution of larvae (D = 69.07%, C = 100%) and adults (D = 31.86%, C = 100%), followed by Cx tritaeniorhynchus (D = 38.14%, C = 100%) and Anopheles maculipennis s.l. (D = 11.05%, C = 100%) as adults. Aedes vexans was the dominant (7.85%) species, but it had a sporadic (20%) distribution. Culex torrentium and Culiseta morsitans were added as the new species to the checklist of mosquitoes in Mazandaran Province. Due to the potential role, Cx. pipiens s.s. as a vector of various pathogens, further ecological studies are recommended.

    Full Text Available Visceral leishmaniasis (VL as one of the most important human parasitic disease is endemic in some parts of Iran. Several cases of VL have been reported recently in the Ilam Province. The current study aimed to assess the present status of human VL in the region.A random cluster sampling method was used to collect 456 serums samples from the children up to 12 years of age and 10% of adults living in urban and rural areas of the province. All the collected serum samples were tested by direct agglutination test (DAT to detect anti- Leishmania infantum antibodies.Of the examined 456 serum samples with direct agglutination test (DAT, only 21 (0.43% sera showed anti- Leishmania antibodies at titers 1:400 and higher. Distribution of anti- Leishmania antibodies titers were: 1:400(n=4, 1:800(n=11, 1:1600(n=3, 1:3200(n=1, and 1:6400(n=1. Individuals with titers ≥1:3200 showed clinical signs and symptoms such as fever and splenomegaly. The highest and lowest seropositivity were observed in the age groups of 5-9 and >15 years old, respectively. There were no significant difference between the rate of seropositivity in males and females.VL with a low prevalence circulates in some parts of Ilam province, particularly in the southern parts. Complementary studies should be needed to find animal reservoir hosts and vectors. Furthermore, health systems and physicians should pay particular attention to the disease.

    Full Text Available BACKGROUND: Golestan Province in northeastern Iran has one of the highest incidences of esophageal squamous cell carcinoma (ESCC in the world with rates over 50 per 100,000 person-years in both sexes. We have analyzed TP53 mutation patterns in tumors from this high-risk geographic area in search of clues to the mutagenic processes involved in causing ESCC. METHODOLOGY/PRINCIPAL FINDINGS: Biopsies of 119 confirmed ESCC tumor tissue from subjects enrolled in a case-control study conducted in Golestan Province were analyzed by direct sequencing of TP53 exons 2 through 11. Immunohistochemical staining for p53 was carried out using two monoclonal antibodies, DO7 and 1801. A total of 120 TP53 mutations were detected in 107/119 cases (89.9%, including 11 patients with double or triple mutations. The mutation pattern was heterogeneous with infrequent mutations at common TP53 "hotspots" but frequent transversions potentially attributable to environmental carcinogens forming bulky DNA adducts, including 40% at bases known as site of mutagenesis by polycyclic aromatic hydrocarbons (PAHs. Mutations showed different patterns according to the reported temperature of tea consumption, but no variation was observed in relation to ethnicity, tobacco or opium use, and alcoholic beverage consumption or urban versus rural residence. CONCLUSION/SIGNIFICANCE: ESCC tumors in people from Golestan Province show the highest rate of TP53 mutations ever reported in any cancer anywhere. The heterogeneous mutation pattern is highly suggestive of a causative role for multiple environmental carcinogens, including PAHs. The temperature and composition of tea may also influence mutagenesis.

Methods: In this descriptive study, files of 34 hospitalized patients who underwent surgery for hydatid cysts during 2003-2008 in Mazandaran province were analyzed. Also, 1 678 343 sheep, 815 635 goats, 451 743 cattle and 1 130 buffaloes were examined carefully for the presence of hydatid cysts in slaughterhouse of Mazandaran province, during 2003-2008. Results: In human, the highest rate of hydatidosis was related to 30-39 age group. Infection rate in females was higher than that in males (61.8% vs 31.2%. Cyst involvement of different organs was as follows: liver 76.5%, lung 13.5%, spleen 5.4%, gall bladder 2.7% and abdomen septum 2.9%. In slaughtered animals, overall, 6.38% had liver cyst and 12.70% had lung cyst. Involvement of liver and lung in sheep, goat, cattle and buffalo were 7.09% and 14.70%; 5.12% and 10.20%; 5.97% and 9.60%; and 14.90% and 13.18%, respectively. In sheep, goat and cattle the most infected organ was lung but in buffalo it was liver. Conclusions: The results show that in human, all age groups and both sexes are exposed to hydatidosis. In livestock it causes economic loss to veterinary industries. Therefore, appropriate control method is needed to prevent this zoonotic disease.

    Full Text Available Abstract Background Suicide is an important social tragic phenomenon which occurs by different tools or methods in different communities. Considering deliberate poisoning as a common and important method in Ilam province for suicide, the present study was launched to epidemiologically assess committing suicide in Ilam province, Iran, based on intentional poisoning. Methods By a retrospective study, all the recorded data associated with intentional poisoning suicide in Ilam Province during 1993–2013 were analyzed. All the demographic variables and the suicides’ outcomes were analyzed using the Chi-Square test, and the univariate and multivariate logistic regression models. Results Totally, 6794 cases of suicide (annual incidence rate of 87.28/ 100, 000 associated with poisoning were evaluated. The incidence rate of suicide attempts was 84.63/ 100, 000 (94.51 in female and 74.98 in male and the incidence rate of completed suicide was 2.17/ 100, 000 (1.94 in female and 2.40 in male. Also, the highest rates of attempted and completed suicide (annual incidence rate of 172.42 and 4.14, respectively were attributed to the age group of 15–24 year. Conclusion Females had a greater tendency to commit suicide by poisoning, and the lower level of education, the age group of 15–24 years and single individuals were more associated with suicide using poisonings. The incidence of attempted suicide in females and completed suicide in males was higher in this method. Considering the high rate of suicide by poisoning, further attention and supervision on the sale and reserve of drugs and poisons is necessary. Meanwhile, it seems that due to momentary emotions during the pubertal stage, the risk of committing suicide is increased especially among unemployed individuals; therefore, performing an extensive psychotherapy intervention is needed in the societies with younger populations.

    Full Text Available Introduction: Regarding to the ever-increasing consumption of egg and consequently enhancement of its production during recent years, consideration to this output's market integration has special importance. Considering the fact that information on market integration may provide specific evidence as to the competitiveness of market, the effectiveness of arbitrage and the efficiency of pricing could be, likewise, useful to guide subsequent interventions aimed at improving the performance of market. In this context, in present study, validity of Law of One Price (LOP will be tested in the egg market and among selected provinces. Materials and Methods: Nonlinearity naturally extracted from local market due to existence of transportation and other transaction costs, so common cointegration test results are not suitable for market integration. In this study, at first, for being sure that series follow nonlinear behavior, Luukkonen et al. (1988 and BDS nonlinearity tests were used. Then for testing Law of One price in the egg market, nonlinear unit root test proposed by Emmanouilides and Fousekis (2012, which is an auxiliary regression for ESTAR model, was used. The data are daily retail prices of egg with the sample period ranging from April 2006 to march 2014 for north-west provinces of Iran including West Azerbaijan, East Azerbaijan, Ardebil, Tehran and Zanjan, which were obtained from State Live Stock Affairs Logistics Incorporated Company. Results and Discussion: Based on the DF-GLS unit root test, the null hypothesis of unit root for egg price differentials was rejected. So, all series of price differentials are stationary. In the next step nonlinearity of price differentials of egg between two provinces was examined. In BDS test, at the beginning, an ARMA model was estimated then the test was carried out to the residual of estimated model with embedding dimension (m 2-8 and the dimensional distance (ε chosen equals to 0.5 and 2 times of

    Full Text Available BACKGROUND: Echinococcus multilocularis is the source of alveolar echinococcosis, a potentially fatal zoonotic disease. This investigation assessed the presence of E. multilocularis infection in definitive hosts in the Chenaran region of Razavi Khorasan Province, northeastern Iran. METHODOLOGY/PRINCIPAL FINDINGS: Fecal samples from 77 domestic and stray dogs and 14 wild carnivores were examined using the flotation/sieving method followed by multiplex PCR of mitochondrial genes. The intestinal scraping technique (IST and the sedimentation and counting technique (SCT revealed adult Echinococcus in the intestines of five of 10 jackals and of the single wolf examined. Three jackals were infected only with E. multilocularis but two, and the wolf, were infected with both E. multilocularis and E. granulosus. Multiplex PCR revealed E. multilocularis, E. granulosus, and Taenia spp. in 19, 24, and 28 fecal samples, respectively. Echinococcus multilocularis infection was detected in the feces of all wild carnivores sampled including nine jackals, three foxes, one wolf, one hyena, and five dogs (6.5%. Echinococcus granulosus was found in the fecal samples of 16.9% of dogs, 66.7% of jackals, and all of the foxes, the wolf, and the hyena. The feces of 16 (21.8% dogs, 7 of 9 (77.8% jackals, and all three foxes, one wolf and one hyena were infected with Taenia spp. CONCLUSIONS/SIGNIFICANCE: The prevalence of E. multilocularis in wild carnivores of rural areas of the Chenaran region is high, indicating that the life cycle is being maintained in northeastern Iran with the red fox, jackal, wolf, hyena, and dog as definitive hosts.

    Full Text Available Tuberculosis is one of the most important zoonotic diseases in the world. Rapid diagnosis of the disease and identification of species is extremely important for proper treatment of the disease as some species of the complex are resistant to the first-line of tuberculosis drugs. The aim of present study was molecular identification of Mycobacterium tuberculosis (MTB complex isolates from Kermanshah Province, Iran, which were submitted to the Tuberculosis Reference Laboratory at Razi Vaccine and Serum Research Institute (Tehran, Iran. To identify the genus Mycobacterium, all isolates were subjected to 16S rRNA polymerase chain reaction (PCR, and PCR-IS6110 was subsequently used to confirm that the isolates belonged to MTB complex. Finally, region of difference (RD typing was used to identify the species in the complex. The results of 16S rRNA and IS6110 PCR analysis showed the presence of 543-bp and 245-bp bands, respectively. Furthermore, 146bp, 172bp, 235bp, and 369bp at RD1, RD4, RD9, and RD12, respectively, were observed during RD typing. Thus, based on the results, all isolates were identified as MTB. It is worth mentioning that most tuberculosis cases are identified on the basis of acid-fast bacilli detection, and antibiotic therapy is immediately initiated subsequently. Moreover, it should be noted that some of these acid-fast positive cases might not be of genus Mycobacterium, and thus, the antibiotics prescribed might threaten the health of the patients. Additionally, if the identified bacilli are not within MTB complex, the drug therapy would differ. However, Mycobacterium bovis, which is a member of MTB complex and is resistant to pyrazinamide, requires exact strain identification. Based on the findings, individual isolates should be identified by RD typing methods, which could clearly discriminate the species from each other.

    The global prevalence of overweight and obesity had risen in recent decades, and obesity is taken into consideration as a public health concern and a major risk factor of common chronic disease. The objective of the present study was to estimate the prevalence of overweight and obesity and to identify its underlying factors among children 2-6 yr of age in Fars Province, southern Iran. A total of 8911 children, aged 2-6 yr age, were selected thorough multi-stage sampling in 30 cities of Fars Province in 2012-13. Overweight and obesity status was assessed through comparison by standard BMI for age and for sex percentiles (NCHS/CDC). In addition, socio-demographic measures obtained from structured questionnaire were compared between normal and overweight plus obese (ow/ob) groups. We used backward stepwise Logistic Regression, Chi-square and Independent sample t-test to relate the underlying factors to the nutritional indices. The prevalence of overweight and obesity was 5.7% (95% CI: 5.2%, 6.1%) and 5.2% (95% CI: 4.7%, 5.6%), respectively. The ow/ob was significantly correlated with male sex, urbanization, type of father's occupation, universal education of mothers, the higher birth weight, low access to household facilities, and not using health-care services (P<0.05). Besides, the logistic regression analysis showed urbanization (OR=1.46, CI: 1.26, 1.70), second sibling (OR=1.183, CI: 1.00, 1.39), and less access to a variety of food groups (OR=1.32, CI: 1.05, 1.65) as ow/ob risk factors. The rate of overweight and obesity in the study population is at an alarming level. Therefore, a preventive program is needed to control ow/ob since early childhood considering the underlying factors for each region and individual groups.

    Human T-cell lymphotropic virus type-1 is an oncornavirus that causes adult T cell leukemia (ATL) HTLV-I-associated myelopathy⁄tropical spastic paraparesis (HAM/TSP). Golestan province is located in North West of Khorasan province known as an endemic area for HTLV-I in Iran. This study aimed to evaluate seroprevalence of HTLV-I in Golestan province. In this cross-sectional descriptive study in 2007, blood samples were collected from 2034 healthy people residing in different parts of Golestan province. Sera were assessed for HTLV-I/II-specific antibodies by ELISA method and reactive samples were confirmed by Western blot. Demographic and serologic data were entered in SPSS version 11.5 and statistical analysis was performed. An overall HTLV-I/II prevalence of 0.7% was observed in 15 cases by ELISA. Six out of 15 were confirmed as HTLV-I by western blot. Regional variation in the prevalence of HTLV-I was observed; 0%, 0%, 0.1%, 1.9%, 0.3%, 0%, and 2.6% tested HTLV-I-positive from west to east of Golestan Province regions, respectively. Seropositivity increased with age. No association between HTLV-I infection and sex status was detected. Highest rate of HTLV-I seroprevalence was shown in east of this region located in neighborhood with Khorasan province, the only confirmed endemic area in Iran. It seems that eastern area of our province is endemic for HTLV-I. Further comprehensive detailed epidemiological and molecular studies are recommended.

    Full Text Available Introduction: Plant diseases caused by geminiviruses are one of the main constraints of legume production in the world. They are responsible for a constraint on production of various crops. Geminiviruses are characterized by their twinned icosahedral particles and their single-stranded DNA genome. The family Geminiviridae is grouped into four genera: Begomovirus, Mastrevirus, Curtovirus and Topocuvirus (Brown and Moriones, 2012. Recent reports for geminiviruses show that viruses such as Spinach curly top Arizona virus (SCTAV and Beet curly top Iran virus (BCTIV (Yazdi et al., 2008 can be grouped in a new genus, Becurtovirus (ICTV 2012;http://www.ictvonline.org/virusTaxonomy.asp. Zanjan Province is one of the main regions for growing bean in Iran. Various geminiviruses have been reported from bean included: Bean golden mosaic virus (BGMV, BCTIV, Bean Calico mosaic virus (BCaMV and Bean dwarf mosaic virus (BDMV. In this study in order to determine the type and distribution of geminivirus/es causing bean diseases, samples were collected from Zanjan province and then tested for the presence of geminiviruses using polymerase chain reaction and rolling circle amplification systems. Materials and Methods: Some of the geminiviruses cause disease in the bean. To identify geminiviruses in the bean, sixty samples were collected from Zanjan, Khdabadeh, KhoramDareh and Abhar in summer 2014. These samples were collected according to the symptoms such as golden mosaic, curling, malformation, blistering, yellowing of leaves and plant stunting. After DNA extraction, viral infection was tested by polymerase chain reaction (PCR using degenerate primers, PAL1V 1978/ PAR1C 496 and Primer B/ Primer V181. Based on the disease symptoms and results of PCR, four samples were selected to confirm the presence of geminiviruses and also to amplify the full-length genome using a rolling cycle amplification (RCA kit.

    Intestinal parasitic infections are among the most common infections and health problems worldwide. Due to the lack of epidemiologic information of such infections, the prevalence of, and the risk factors for, enteric parasites were investigated in residents of Roudehen, Tehran Province, Iran. In this cross-sectional study, 561 triple fecal samples were collected through a two-stage cluster-sampling protocol from Jun to Dec 2014. The samples were examined by formalin-ether concentration, culture, and with molecular methods. The prevalence of enteric parasites was 32.7% (95% CI 27.3-38). Blastocystis sp. was the most common intestinal protozoan (28.4%; 95% CI 23.7-33.0). The formalin-ether concentration and culture methods detected Blastocystis sp., Entamoeba coli , Giardia intestinalis , Dientamoeba fragilis , Iodamoeba butschlii , Entamoeba complex cysts or trophozoite , Chilomastix mesnilii , and Enterobius vermicularis . Single-round PCR assay for Entamoeba complex were identified Entamoeba dispar and E. moshkovskii . E. histolytica was not observed in any specimen. Multivariate analysis showed a significant association of parasites with water source and close animal contact. There was no correlation between infections and gender, age, occupation, education, or travel history. Protozoan infections were more common than helminth infections. This study revealed a high prevalence of enteric protozoan parasite infection among citizens of Rodehen. As most of the species detected are transmitted through a water-resistant cyst, public and individual education on personal hygiene should be considered to reduce transmission of intestinal parasites in the population.

    Breast cancer is the most common cancer and the second common cause of cancer-induced mortalities in Iranian women. There has been a rapid development in hazard models and survival analysis in the last decade. The aim of this study was to evaluate the prognostic factors of overall survival (OS) in breast cancer patients using accelerated failure time models (AFT). This was a retrospective-analytic cohort study. About 313 women with a pathologically proven diagnosis of breast cancer who had been treated during a 7-year period (since January 2006 until March 2014) in Sanandaj City, Kurdistan Province of Iran were recruited. Performance among AFT was assessed using the goodness of fit methods. Discrimination among the exponential, Weibull, generalized gamma, log-logistic, and log-normal distributions was done using Akaik information criteria and maximum likelihood. The 5 years OS was 75% (95% CI = 74.57-75.43). The main results in terms of survival were found for the different categories of the clinical stage covariate, tumor metastasis, and relapse of cancer. Survival time in breast cancer patients without tumor metastasis and relapse were 4, 2-fold longer than other patients with metastasis and relapse, respectively. One of the most important undermining prognostic factors in breast cancer is metastasis; hence, knowledge of the mechanisms of metastasis is necessary to prevent it so occurrence and treatment of metastatic breast cancer and ultimately extend the lifetime of patients.

    Full Text Available Atrazine, a herbicide widely used in corn production, is frequently detected as pesticide in water resources. In this research, four agricultural fields with a long history of atrazine application in Shiraz and its vicinity in Fars province of Iran, have been studied to determine the fate of atrazine through the passage of time. These four farms were cultivated under a crop rotation (corn-wheat during the past 10 years. Samples were collected from four soil profiles of 0-10, 10-20, 20-40, and 40-60 cm soil depth at different times. The time intervals for soil sampling started before atrazine application and continued until no atrazine was detected. According to the general linear model, there was no significant difference between atrazine residual concentrations and the soil moisture and depth (p≥0.05. But, significant difference between atrazine residual concentrations and the sampling regions was observed (p<0.001. Based on the data, atrazine leaching and dissipation rate in different soil profiles in the four sampling regions were high and significant. Therefore, there is a high risk of atrazine pollution in groundwater resources of the region.

    Radon is a natural radioactive gas which is produced by decay of the Uranium and emanates from the ground. According to EPA and WHO studies, Radon is the second largest cause of lung cancer after smoking. According to the registered information report of cancer cases from 1985 till now, lung cancer is the second most common death cause in all cancers (after stomach cancer) in Iran. Based on the report of the National Institute of Cancer and the Iranian Ministry of Health, the total death due to lung cancer were estimated to be 5.7%, 4.82%, 4.48% 3.76%, 9% in mentioned provinces. An investigation was made on the relation between lung cancer risk and radon levels. The risk for smoking, the first leading cause of lung cancer, is more greater than for radon, the second leading cause. The results show that there is no direct relation between increased risk of lung cancer from indoor radon exposure, but it cannot be ignored that indoor radon should be considered as a cause of lung cancer in the general population

    Full Text Available Background: The aim was to study the gastro-intestinal helminths of stray dogs of Garmsar, Sem­nan Province, Central Iran, and its impacts on human health and animal production.Methods: During 2006, the alimentary tracts of 50 stray dogs at necropsy, selected from villages around Garmsar, were removed, and examined for helminth infections. Subsequently helminths were collected from the contents of each part and scraped sample of small intestines of washed materials in a 100-mesh sieve. To identify the species of helminths, the nematodes were cleared in lactophenol and cestodes were stained using carmine acid.Results: Mixed infection was the rule and 40 dogs (80% harbored more than one species of helminth. Taenia hydatigena was the most prevalent species (80% followed by Echinococcus granulosus (64%, Toxocara canis (22%, Mesocestoides lineatus (12%, Taenia multiceps (10% and Dipylidium caninum (4%. The mean intensity of worm infection was low (1-3 ex­cept for that of E. granulosus (645. No significant difference was noticed between sex, age and most helminth infections except for that of sex and T. hydatigena (P=0.001 as well as age and T. canis (P=0.001.Conclusion: Although human infection with T. hydatigena is unlikely, but other helminths re­ported in this study are of zoonotic importance, and may pose a threat to community health, and reduce the productions of ruminants harboring taeniid metacestodes.

The mean intensity of worm infection was low (1–3) except for that of E. granulosus (645). No significant difference was noticed between sex, age and most helminth infections except for that of sex and T. hydatigena (P=0.001) as well as age and T. canis (P=0.001). Conclusion Although human infection with T. hydatigena is unlikely, but other helminths reported in this study are of zoonotic importance, and may pose a threat to community health, and reduce the productions of ruminants harboring taeniid metacestodes.

    Aflatoxin M(1) (AFM(1)) is the metabolite of aflatoxin B1 (AFB(1)) and is found in milk when lactating animals are fed with contaminated feedstuff. The presence of AFM(1) in milk, pose a major risk for humans especially kids as it can have immunosuppressive, mutagenic, teratogenic and carcinogenic effects. The present study is aimed to investigate the occurrence of AFM(1) in subsidized pasteurized milk in Babol, Mazandaran Province, Iran. Some 72 pasteurized milk packages were collected from supermarkets in various districts of city during January to March 2006. Milk samples were centrifuged and amounts of 100 μl of skimmed milk were tested for AFM(1) contamination by competitive ELISA. All the samples (100%) exhibited contamination with AFM(1). The contamination levels means in January, February, and March were 227.85, 229.64, and 233.1ng/l, respectively. The amount of AFM(1) in all the samples were above 50ng/l, the threshold set by the European community regulations. Monitoring of AFM(1) level should be part of quality control procedures in dairy factories, particularly the ones providing infant's milk. Production of safer and healthier milk and other dairy products with minimum AFM(1) level can be achieved by adopting prophylactic measures including control of humidity and water content of feedstuff, which favors mould production.

    Background Acanthamoeba spp. are free-living amoebae commonly found in the environmental sources such as water, soil, and air. This ubiquitous amoeba is the causative agent of amoebic keratitis (AK). The objective of the present study was to investigate the presence of Acanthamoeba spp. in water and soil sources in Ahvaz City, Khuzestan Province, southern Iran. Methods In general, 110 samples of water and soil were taken from different localities of Ahvaz including agricultural canals, rivers, and swimming pools. Filtration and cultivation were carried out on non-nutrient agar medium (NNA). Axenic cultivation was performed for all of positive isolates. PCR analysis was conducted on positive samples. Sequencing was done for 15 PCR products. Genotypes were identified by Blast search and homology analysis. Results Acanthamoeba spp. was found in 43 (71.6%) of samples of water and 13 (26%) soil samples. Genotyping of 15 samples proved that Acanthamoeba belonged to T4 (86.6%), T2 (6.6%), and T5 (6.6%) genotypes. Conclusion TYI-S-33 medium could be better than PYG medium for Acanthamoeba axenic culture. PMID:23323088

    Full Text Available Background: Eosinophilia occurs in a wide variety of situations such as parasitic infections, aller­gic disorders, and malignancies. Most cases of eosinophilia of parasitic origin, especially those with a tissue migration life cycles consists of human infections by helminth parasites. The aim of present study was to determine the parasitic causes of eosinophilia in patients in a major endemic area of human fascioliasis in Gilan Province, northern part of Iran.Methods: One hundred and fifty patients presenting with an elevated eosinophilia attending infec­tious disease clinics with or without clinical symptoms, were examined. After clinical his­tory evaluation and physical examination, coprological examinations were performed using the formalin-ether and the Kato-Katz techniques for detection of Fasciola sp. and intestinal parasites.Results: Forty two percent of patients were infected with S. stercoralis, nine (6% were found to be infected with Fasciola sp. while only a single patient (0.7% were infected by Ttrichostrongy­lus sp.Conclusion: Local clinicians in Gilan may consider eosinophilia as a suggestive indication for diagnosis of human fascioliasis, especially when microscopic stool and/or serological tests are negative. Based on the results, local physicians should consider S. stercoralis as the potential causes of eosinophilia in patients with elevated eosinophilia.

    To understand and contrast the origins of ultramafic assemblages from basaltic and kimberlitic rocks and their associated deposits, such as V-Ti magnetite and Ni-Cu-(PGE) sulfide deposits and diamond, applicable thermobarometers were evaluated and applied to the ultramafic assemblages from the Emeishan Large Igneous Province (ELIP), Southwest China and from the Nikos and Zulu Kimberlites of Nunavut, Canada. The ELIP is located in the Yangtze Block, Southwest China and composed of Permian Emeishan Flood basalt (EFB) and associated layered mafic-ultramafic intrusions. Some of these intrusions host V-Ti magnetite deposits; while others contain Ni-Cu-(PGE) sulfide deposits. It is not clear why some intrusions host magnetite deposits and others contain sulfide deposits. The P-T conditions for the ultramafic assemblages from the mafic-ultramafic intrusions in the ELIP were calculated in order to understand the origins and the associated mineral deposits. The ultramafic assemblages are peridotite, olivine pyroxenite, pyroxenite in the layered intrusions and the common minerals include spinel, olivine, clinopyroxene, orthopyroxene, and minor magnetite and ilmenite. Using a two pyroxene thermometer and a Ca-Mg exchange barometer between olivine and clinopyroxene, a spinel-olivine-clinopyroxene-orthopyroxene assemblage from the Xinjie intrusion yields a T-P of 905°C and 17 kbar; and a similar assemblage from the Jinbaoshan intrusion yields a T-P of 1124°C and 31 kbar. The Nikos kimberlite, near Elwin Bay on Somerset Island, is located at the northeast end of the northeast-southwest kimberlite zone; and the Zulu kimberlite is located on the neighboring Brodeur Peninsula of Baffin Island, Nunavut. The ultramafic assemblages from the Canadian Kimberlites include garnet lherzolite, garnet-spinel lherzolite, spinel lherzolite, dunite, garnet websterite, spinel websterite and garnet clinopyroxenite. The calculated P-T conditions are in the range of 760 to 1180°C and 25 to 60

    While there has been a number of consumers' studies looking at factors that influence individuals' attitudes and behavior toward GM foods, few studies have considered agricultural professionals' intentions in this regard. This study illuminates agricultural professionals' insights toward GM foods in Southwest Iran. A random sample of 262 respondents was studied. The results indicated that the majority of the respondents had little knowledge about GM foods. They perceived few benefits or risks of GM foods. Their perceived benefits and trust in individuals and institutions had positive impacts on the behavioral intentions of the agricultural professionals. The results also revealed that the low knowledge level of the respondents had a negative impact on the behavioral intentions toward GM foods. This state of affairs is problematic, either GM foods have serious problems or the knowledge conveyed to the Iranian agricultural experts is inappropriate. We recommend a well defined communication strategy to provide information in such a way that allows individuals to feel adequately informed about GM foods. Furthermore, the development of trust and knowledge regarding GM foods can be greater when risk analysis frameworks are transparent, risk assessment methodologies are objective, all stakeholders are engaged in the risk management process, and risk communication focuses on consumers.

    Water shortage and climate change are the most important issues of sustainable agricultural and water resources development. Given the importance of water availability in crop production, the present study focused on risk assessment of climate change impact on agricultural water requirement in southwest of Iran, under two emission scenarios (A2 and B1) for the future period (2025-2054). A multi-model ensemble framework based on mean observed temperature-precipitation (MOTP) method and a combined probabilistic approach Long Ashton Research Station-Weather Generator (LARS-WG) and change factor (CF) have been used for downscaling to manage the uncertainty of outputs of 14 general circulation models (GCMs). The results showed an increasing temperature in all months and irregular changes of precipitation (either increasing or decreasing) in the future period. In addition, the results of the calculated annual net water requirement for all crops affected by climate change indicated an increase between 4 and 10 %. Furthermore, an increasing process is also expected regarding to the required water demand volume. The most and the least expected increase in the water demand volume is about 13 and 5 % for A2 and B1 scenarios, respectively. Considering the results and the limited water resources in the study area, it is crucial to provide water resources planning in order to reduce the negative effects of climate change. Therefore, the adaptation scenarios with the climate change related to crop pattern and water consumption should be taken into account.

    The Fars province is located in the south-west region of Iran where different nuclear sites has been established, such as Bushehr Nuclear Power Plant. In this research, 92 water samples from the water supplies of Shiraz city and springs of the Fars province were investigated with regard to the concentrations of natural radioactive elements, total uranium, 226 Ra, gross alpha and gross beta. 226 Ra concentration was determined by the 222 Rn emanation method. To measure the total uranium concentration, a laser fluorimetry analyzer (UA-3) was used. The mean concentration of 226 Ra in Shiraz's water resources was 23.9 mBq l -1 , while 93% of spring waters have a concentration 2 mBq l -1 . The results of uranium concentration measurements show the mean concentrations of 7.6 and 6 mg l -1 in the water of Shiraz and springs of Fars, respectively. The gross alpha and beta concentrations measured by the evaporation method were lower than the limit of detection of the measuring instruments used in this survey. The mean annual effective doses of infants, children and adults from 238 U and 226 Ra content of Shiraz's water and spring waters were estimated. According to the results of this study, the activity concentration in water samples were below the maximum permissible concentrations determined by the World Health Organization and the US Environmental Protection Agency. Finally, the correlation between 226 Ra and total U activity concentrations and geochemical properties of water samples, i.e. pH, total dissolve solids and SO 4 2- , were estimated. (authors)

    The distribution of 10 macronutrients and trace metals in the arable soils of Isfahan Province, their phytoavailability, and associated health risks were investigated; 134 plant and 114 soil samples (from 114 crop fields) were collected and analyzed at harvesting time. Calculation of the soil pollution index (SPI) revealed that arable soil polluted by metals was more severe in the north and southwest of the study area. The results of cluster analysis indicated that Pb, Zn, and Cu share a similar origin from industries and traffic. The concentrations of macronutrients and trace metals in the sampled crops were found in the order of K > Ca > S > Mg > P and Fe > Mn > Zn > Cu > Pb, respectively, whereas calculation of the bioconcentration factor (BCF) indicated that the accumulation of the investigated elements in crops was generally in the order of S ≈ K > P > Mg > Ca and Zn > Cu > Mn > Pb > Fe, respectively. Thus, various parameters including crop species and the physical, chemical, and biological properties of soil also affected the bioavailability of the elements besides the total element contents in soil. Daily intake (DI) values of elements were lower than the recommended daily intake (RDI) levels in rice grains except for Fe and Mn, but for wheat grains, all elements displayed DI values higher than the RDI. Moreover, based on the hazard index (HI) values, inhabitants are experiencing a significant potential health risk solely due to the consumption of wheat and rice grains (particularly wheat grains). Mn health quotient (HQ) also indicated a high risk of Mn absorption for crop consumer inhabitants.

    Full Text Available Background: Intestinal parasitic infections are among the most common infections and health problems worldwide. Due to the lack of epidemiologic information of such infections, the prevalence of, and the risk factors for, enteric parasites were investigated in residents of Roudehen, Tehran Province, Iran.Methods: In this cross-sectional study, 561 triple fecal samples were collected through a two-stage cluster-sampling protocol from Jun to Dec 2014. The samples were examined by formalin-ether concentration, culture, and with molecular methods.Results: The prevalence of enteric parasites was 32.7% (95% CI 27.3–38. Blastocystis sp. was the most common intestinal protozoan (28.4%; 95% CI 23.7–33.0. The formalin-ether concentration and culture methods detected Blastocystis sp., Entamoeba coli, Giardia intestinalis, Dientamoeba fragilis, Iodamoeba butschlii, Entamoeba complex cysts or trophozoite, Chilomastix mesnilii, and Enterobius vermicularis. Single-round PCR assay for Entamoeba complex were identified Entamoeba dispar and E. moshkovskii. E. histolytica was not observed in any specimen. Multivariate analysis showed a significant association of parasites with water source and close animal contact. There was no correlation between infections and gender, age, occupation, education, or travel history. Protozoan infections were more common than helminth infections.Conclusion: This study revealed a high prevalence of enteric protozoan parasite infection among citizens of Rodehen. As most of the species detected are transmitted through a water-resistant cyst, public and individual education on personal hygiene should be considered to reduce transmission of intestinal parasites in the population.

    We explored survival of skin cancer and its determinants in Kurdistan province of Iran. In a retrospective cohort design, we identified all registered skin cancer patients in Kurdistan Cancer Registry from year 2000 to 2009. Information on time and cause of death were obtained from Registrar's office and information on type, stage and anatomic locations were extracted from patients' hospital records. Additional demographic information was collected via a telephone interview. We calculated the 3 and 5 years survival. Survival experiences in different groups were compared using log rank test. Cox proportional hazard model was built and hazard ratios and their 95% confidence intervals were calculated. Of a total of 1353, contact information for 667 patients were available, all of which were followed up. 472 telephone interviews were conducted. Mean follow-up time was 34 months. We identified 78 deaths in this group of patients and 44 of them were because of skin cancer. After controlling for confounding, tumour type, anatomical location, and diseases stage remained significantly associated with survival. Hazard ratios for death because of squamous cell carcinoma was 74.5 (95%CI: 4.8-1146) and for melanoma was 24.4 (95%CI: 1.3-485) compared with basal cell carcinomas. Hazard ratio for tumours in stage 4 was 16.7 (95%CI: 1.8-156.6) and for stage 3 was 16.8 (95%CI: 1.07-260) compared with stage 1 and 2. Tumour stage is independently associated with survival. Relatively low survival rates suggest delayed diagnosis. Increasing public awareness through media about the warning signs of skin cancers could increase the chance of survival in these patients.

    Full Text Available Sericulture and silk production are among the activities that can, along with other agricultural activities, generate income for rural households in a short period of time. The objective of the present study was to identify factors influencing the adoption of sericulture by farmers in Guilan province, Iran. The sericulture farmers of Langarud and Shaft counties (N = 4187, were included in the statistical population of the study. The sample size was determined to be 198, using the least sample size table of Bartlett et al. (2001 and subsequently, the size of the second group, i.e., non-sericulturists, was specified from these regions. The research tool was a questionnaire whose face and content validity was confirmed by a panel of experts. The reliability of the research tool was evaluated by alpha Cronbach estimated α value to be 0.78. The results revealed that sericulture adoption was significantly related to all demographic characteristics except gender including age, number of dependents, education level, and experience in sericulture as well as technical and economic characteristics including the type of cocoonary ownership, profitability of sericulture given its shorter rearing period compared to other agricultural activities, willingness to rehabilitate coronary, and willingness to attend sericulture and other relevant courses. The studied groups differed significantly in terms of the impact of all supportive policies including the provision of loans and facilities for the rehabilitation and construction of coronaries, the insurance of silkworm rearing, the training and promotion of sericulture and relevant activities, free distribution of improved saplings, distribution of high-yielding silkworm eggs, and the guaranteed purchase of cocoons. The results revealed that all supportive policies played an effective role in the adoption of sericulture. However, free distribution of improved saplings, distribution of high-yield silkworm eggs

    A total of 229 confirmed cholera cases were reported in Alborz Province during an outbreak that lasted from June 2011 to August 2011. This study aimed to identify potential sources of transmission in order to determine suitable interventions in similar outbreaks. In other words, the lessons learned from this retrospective study can be utilized to manage future similar outbreaks. An age-matched and sex-matched case-control study was conducted during the outbreak. For each case, two control subjects were selected from the neighborhood. A case of cholera was defined as a bacteriologically confirmed case with signs and symptoms of cholera. This study was conducted from June 14, 2011 through August 23, 2011. The data were analyzed by calculating odds ratios (ORs) using the logistic regression method. In this outbreak, 229 confirmed cholera cases were diagnosed. The following risk factors were found to be associated with cholera: consumption of unrefrigerated leftover food (OR, 3.05; 95% confidence interval [CI], 1.72 to 5.41), consumption of vegetables and fruits in the previous three days (OR, 2.75; 95% CI, 1.95 to 3.89), and a history of traveling in the previous five days (OR, 5.31; 95% CI, 2.21 to 9.72). Consumption of vegetables and fruits has remained an unresolved risk factor in cholera outbreaks in Iran in recent years. In order to reduce the risk of cholera, sanitary standards for fruits and vegetables should be observed at all points from production to consumption, the population should be educated regarding hygienic food storage during outbreaks, and sanitary standards should be maintained when traveling during cholera outbreaks.

    Full Text Available Linguatula serrata, well known as tongue worm; is an aberrant cosmopolitan parasite, which inhabits the canine respiratory system (final host. The discharged eggs infect many plant feeder animals including human causing visceral and nasopharyngeal linguatulosis which is known as “Marrara syndrome”. In current study, the prevalence of infection with L. serrata nymphs in mesenteric lymph nodes (MLNs of slaughtered camels was investigated in Isfahan Province, Iran. The MLNs of 232 slaughtered camels, including 115 females and 117 males, were examined for L. serrata nymphs. Camels were categorized into four age groups, namely under six months, six months to two years, two to four years and greater than four years. Also, the morphometrics of the nymphs were measured using the classic parasitology methods. Results showed that 21.12% of examined camels were infected with L. serrata. Age and sex had no significant effect on the prevalence of this parasite in camels. The size of the different parts of nymphs’ body were recorded and evaluated. The infection rate to the nymphs of parasite in hemorrhagic and black-colored lymph nodes were significantly (P ≤ 0.05 higher than the infection rate in normal-colored nodes. Also, results showed that in soft lymph nodes, the infection rate was significantly (P ≤ 0.05 more than those of normal and hard nodes. A high prevalence of infection in camels suggests possibility of similar high rate of infection in other animals, and people in the investigated area. This, in turn, emphasizes the need for more preventive measures to reduce the risk of zoonotic outbreaks.

    Suicide by aggressive physical methods such as firearms, hanging, and jumping is well known; however, different factors may influence a person while selecting a particular method. The aim of this study was to investigate the epidemiological factors involved in the selection and use of different physical methods for suicide over a long-term period in Ilam province, Iran. The present study was conducted retrospectively between 1993 and 2013 using recorded data from a comprehensive system for registration of suicide attempts in Ilam University of Medical Sciences. The epidemiological characteristics included person, time and place variables, and the outcomes of the suicide attempts. The chi square, univariate and multivariate logistic regression models were used for data analysis. Totally, 1516 suicide attempts were evaluated (the annual incidence rate: 19/100,000 individuals). The most commonly used suicide method in females (88.4%) and males (38.9%) was self-immolation. Furthermore, the annual incidence rate among males and females was within the age group of 15-24 years (24.6 and 47.8/100,000 individuals). The risk of death by suicide in the age group of 55-64 years was 2.93 compared with the age group of 10-14 years (OR = 2.93; 95% CI = 0.64-13.54, P = 0.168). This study revealed that self-immolation was the most selected physical method of suicide and had the highest incidence rate, and inflicted the survivors with severe physical and mental complications. In order to reduce the use of physical methods, especially self-immolation, life skills training becomes more important than ever.

    Full Text Available Background: Imbalanced diet, as it may cause micronutrient malnutrition has been known as a causal factor for several chronic diseases. Several studies in Iran have shown that some micro-nutrient deficiencies are prevalent and of high concern. Minerals such as calcium and iron can supply physical and mental health as well as survival, and growth development. In this study, Nutrient density analysis was used to display Iranian households' diet quality. Methods: In this descriptive-analytical study, the diet quality of seven provinces, namely Eastern Azarbaijan, Isfahan, Tehran, Khorasan, Khouzestan, Sistan Balochestan and Fars was assessed in terms of calcium and iron. To do so, the data were obtained through national household food consumption survey conducted by National Nutrition & Food Technology Research Institute, 2000-02, in Iran. Results: Generally, 80% of households' calcium density was less than the standard value and this rate was 40-70% for iron. Index of nutrition quality (INQ for calcium and iron were respectively almost 1/2 and 1/3 of requirements in all provinces. Conclusions: There were significant differences in calcium intake density between the rural and urban households however; there were no differences between the selective provinces and all over the country

    The Caspian region (including the Golestan, Mazandaran, and Guilan provinces of Iran) occupies 58,678 square kilometers (22,651 square miles) and has a population of 6,270,192, according to the census of 1996. This part of Iran is attractive to tourists because of its proximity to the Caspian Sea. In addition, the region boasts invaluable forests and grasslands, and is the exclusive producer in the country of key agricultural crops like rice and tea. The lack of systematic solid waste management has put this region on the edge of irreparable environmental damage. The large number and dispersion of open-dumping landfills, as well as the faded role of functional elements like waste minimization and processing, have sped up the environmental deterioration. This article evaluates the current status of solid waste management in the Caspian region and suggests practical alternatives. As a result of a field and desk study, the authors offer some instructions for separation of putrescibles, paper and cardboard, plastics, and so forth. Finally, after considering all aspects of the environmental impact assessments for different alternatives, the authors recommend the construction of two compost-producing facilities in Golestan province with a combined capacity of 500 metric tons per day and a total cost of $60,000, and four incineration sites in southern and southwestern parts of the region (Mazandaran and Guilan provinces) with a total capacity of 2,000 metric tons per day and total cost of $75 million.

    Full Text Available Introduction The Varandan Ba-Pb-Cu deposits are located15 km southwest of the town of Qamsar and approximately 7 km south west of the Qazaan village, in the Urumieh- Dokhtar magmatic arc. The Kashan region that is situated in west-central Iran hosts several barite-base metal deposits and occurrences, the biggest ones are the Varandan Ba-Pb-Cu (case considered in this study and the Tapeh-Sorkh (Khalajmaasomi et al., 2010 and Dorreh Ba (Nazari, 1994 deposits. Previous researchers (Izadi, 1996; Farokhpey et al., 2010 have proposed an epithermal model for formation of the Varandan deposit. However, based on some feature of the deposit, it seems that this genetic model may not be correct. Therefore, it is necessary to do more precise research studies on the deposit. The main purpose of this paper is to discuss the genesis of the Varandan deposit based on geological, ore facies, mineralogy, wall rock alterations, and geochemical studies. Materials and methods A field study and sampling was performed during the summer of 2013. To assess the geochemical characteristics of the deposit, about 17 systematic samples from different ore facies of the first, second and third sub-horizon were collected for petrography and mineralogy, and for inductively coupled plasma-atomic emission spectroscopy(ICP-AES, X-ray diffraction (XRD and X-ray fluorescence (XRF geochemical analysis methods. The microscopic studies were done in the optics laboratory of the Shahrood University, and the geochemical analyzes were conducted in laboratories of the Center of Research and Mineral Processing Ore Minerals of Iran, Karaj, Iran. Results The host sequence in the Varandan deposit involves three units, from bottom to top: Unit1: grey, green siliceous tuff, brecciated tuff, crystal tuff and andesite; Unit2: white grey nummulitic limestone, limy tuff and marl: and Unit3: tuff breccia and crystal lithic tuff. Mineralization in the Varandan deposit has occurred as four ore sub

    Background: Crimean-Congo Hemorrhagic Fever (CCHF) is a feverous and hemorrhagic disease endemic in some parts of Iran and caused by an arbovirus related to Bunyaviridae family and Nairovirusgenus. The main virus reservoir in the nature is ticks, however small vertebrates and a wide range of domestic and wild animals are regarded as reservoir hosts. This study was conducted to determine the infection rate of CCHF virus in hard ticks of Sarpole-Zahab County, Kermanshah province, west of Iran. Methods: From total number of 851 collected ticks from 8 villages, 131 ticks were selected randomlyand investigated for detection of CCHF virus using RT-PCR. Results: The virus was found in 3.8% of the tested ticks. Hyalommaanatolicum, H. asiaticum and Rhipicephalus sanguineus species were found to have viral infection, with the highest infection rate (11.11%) in Rh. sanguineus. Conclusion: These findings provide epidemiological evidence for planning control strategies of the disease in the study area. PMID:27308296

    Full Text Available Background: Sporozoan protozoa and enteroparasites cause gastroenteritis. Sporozoa are the major cause of self-limiting diarrhea in immunocompetent patients, however they cause serious diseased in patients with immunosuppression. Objectives: The current study aimed to identify the prevalence of sporozoa and enteroparasites among patients with gastroenteritis referred to the healthcare centers in seven provinces of Iran. Patients and Methods: In this cross-sectional study, 4200 stool samples were randomly collected from patients with gastroenteritis in the selected hospitals of Gilan, East Azerbaijan, Qazvin, Kurdistan, Mazandaran, Tehran and Khorasan-e-Razavi provinces. Primarily samples were examined directly for enteroparasites. The samples were then filtered and concentrated using Paraseb kit. The pellets were fixed, stained by different assays including acid fast staining, Auramin Phenol Fluorescence, Giemsa and light microscopy. Results: The results revealed the overall rate of infection, 3.86% (163 cases, as an indicator of parasitic enteropathogens in Iran. Among the provinces, Khorasan-e-Razavi and Mazandaran with 8.83% (53 cases and 0.34% (2 cases showed the highest and lowest rates of infection, respectively. The frequencies of sporozoa including Cryptosporidium, Microsporidium, Isospora and Cyclospora spp. were 0.1%, 0.1%, 0.07% and 0.02% respectively. Among the parasites, Giardia lambelia, Taenia saginata and Hookworms with 1.78% and 0.02% had the highest and lowest rates of infection, respectively. Regarding the age groups, the highest and the lowest rates of infection were in 0 - 10 (48% and 41 years old and above (6.7% groups, respectively. Conclusions: Despite relatively low prevalence of sporozoa, giardiosis is the most prevalent agent for gastroenteritis amongst 3.86% of parasitic infections in Iran. The current study confirmed the abundance of infection in warm and wet seasons, and more frequency of infections among children

    Full Text Available Understanding environmentally sensitive areas (ESAs prone to desertification can lead to substantial gains in the efficiency of land use planning and partly avoid negative outcomes. The main objectives of this research were the monitoring and mapping of ESAs to desertification in the agro-ecosystem of the Khanmirza plain, Iran, during two time series (2000 and 2013. In the current study, an adjusted “Mediterranean desertification and land use (MEDALUS” approach was applied to identify the most ESAs to desertification in the study area and monitorchanges inthe environmental sensitivity area indicator (ESAIbetween 2000 and 2013 over the studied area.Fivemain thematic indicators have been evaluated including, Soil quality indicator (SQI, Management quality indicator (MQI, Climate quality indicator (CQI, Vegetation quality indicator (VQI, and Irrigation water quality indicator (IWQI. Results show that the areas affected by the critical desertification status covered approximately 7% of the farmlands and the meadowlands in this agro-ecosystem region in the year 2000. Likewise, in 2013, almost 24% of the study area was sensitive to and affected by desertification, giving a rate of increase of approximately 1.3% per year.More than half of the land used for agriculture has been moderately to severely degraded. The results also show that the central places intheregionwere affected by farmlands and meadowlands degradingto barrenlands due to mismanagement and a lack ofeffective planning withland and water resources. However, rehabilitation of irreversibly degraded land requires serious measures that aim torestore the capability of those areas and increase resistance to degradation through effective planning in water and land in the region.

    Full Text Available This paper studies the lithofacies, sedimentary facies, depositional models and reservoir architecture of the rudist-bearing Sar-3 zone of Cretaceous Sarvak in the Southwest of Iran by utilizing coring, thin section, XRD data of five coring wells and 3D seismic data. Research results include the following: According to lithofacies features and their association, the rudist-mound and tidal flat are the main microfacies in the Sar-3 depositional time. By investigating the regional tectonic setting and seismic interpretation, a depositional model was built for the Sar-3 zone, which highlights four key points: 1 The distribution of the rudist-buildup is controlled by the paleo-high. 2 The build-up outside of the wide colonize stage but reached the wave-base level in a short time by regression and formation uplift, and was destroyed by the high energy current, then forming the moundy allochthonous deposition after being dispersed and redeposited. 3 The tidal flat develops widely in the upper Sar-3, and the deposition thickness depends on the paleo-structure. The tidal channel develops in the valley and fringe of the Paleo-structure. 4 The exposure within the leaching effect by the meteoric water of the top of Sar-3 is the main controlling factor of the reservoir vertical architecture. The Sar-3 zone featured as the dualistic architecture consists of two regions: the lower is the rudist reef limestone reservoir and the upper is the tidal condense limestone interlayer. The thickness of each is controlled by the paleo-structure. The Paleo-high zone is the preferential development zone. Based on reservoir characteristics of the different zones, a targeted development strategy has been proposed. Keeping the trajectory in the middle of the oil-layer in the paleo-high, and in the paleo-low, make the trajectory crossing the oil-zone and then keep it in the lower.

    The genetic polymorphisms of 20 autosomal short tandem repeat (STR) loci included in the PowerPlex® 21 kit were evaluated from 2068 unrelated, healthy individuals from the Chinese Han population of Yunnan Province in southwest China. All of the loci reached Hardy-Weinberg equilibrium. These loci were examined to determine allele frequencies and forensic statistical parameters. The genetic relationships among the Yunnan Han and other Chinese populations were also estimated. The combined discrimination power and probability of excluding paternity of the 20 STR loci were 0.99999999999999999999999126 and 0.999999975, respectively. In addition, mutation rates from 4363 parentage cases (2215 trios and 2148 duos) were investigated in this study. A total of 164 mutations were observed in 6578 meioses from the 20 loci. The highest mutation rate was observed in D12S391 (0.30%), and the lowest mutation rates were observed in D13S317 (0.03%) and TPOX (0.03%). The average mutation rate for the 20 loci was estimated to be 1.246 × 10 -3 per meiosis. The mutations were primarily single-step and paternal mutations.

    Full Text Available Soil seed banks are a vital part of ecosystems and influence community dynamics and regeneration. Although soil seed banks in different habitats have been reported, how soil seed banks vary with elevational gradients in different climatic zones is still unknown. This paper investigates seed density, species composition and nonconstituent species of forest soil seed banks in Yunnan Province, southwest China. Similarity between the soil seed bank and standing vegetation was also examined. We collected soil samples from sites spanning 12 elevations in tropical rain forests, subtropical evergreen broad-leaved forests and subalpine coniferous forests, and transported them to a glasshouse for germination trials for species identification. The soil seed banks of tropical and subtropical forests had much higher seed densities and species richness than those of subalpine forests. Seeds of woody species dominated the soil seed banks of tropical and subtropical forests, while herbs dominated those of subalpine forests. The nonconstituent species in the soil seed banks were all herbs and were most abundant in tropical forests, followed by subtropical forests but were completely absent from subalpine forests.

    The amount, frequency, and duration of precipitation have important impact on the occurrence and severity of forest fires. To fully understand the effects of precipitation regimes on forest fires, a drought index was developed with number of consecutive dry days (daily precipitation less than 2 mm) and total precipitation, and the relationships of drought and precipitation with fire activities were investigated over two periods (i.e., 1982-1988 and 1989-2008) in five ecoregions of Yunnan Province. The results showed that precipitation regime had a significant relationship with fire activities during the two periods. However, the influence of the drought on fire activities varied by ecoregions, with more impacts in drier ecoregions IV-V and less impacts in the more humid ecoregions I-III. The drought was more closely related to fire activities than precipitation during the two study periods, especially in the drier ecoregions, indicating that the frequency and the duration of precipitation had significant influences on forest fires in the drier areas. Drought appears to offer a better explanation than total precipitation on temporal changes in fire regimes across the five ecoregions in Yunnan. Our findings have significant implications for forecasting the local fire dangers under the future climate change.

    In this paper stream sediments based geochemical exploration program with the aim of delineating potentially promising areas by a comprehensive stepwise optimization approach from univariate statistics, PCA, ANN, and fusion method PCANN were under taken for an orogenic gold deposit located in the Alut, Kurdistan province, NW of Iran. At first the data were preprocessed and then PCA were applied to determine the maximum variability directions of elements in the area. Subsequently the artificial neural network (ANN) was used for quick estimation of elemental concentration, as well as discriminating anomalous populations and intelligent determination of internal structure among the data. However, both the methods revealed constraints for modeling. To overcome the deficiency and shortcoming of each individual method a new methodology is presented by integration of both "PCA & ANN" referred as PCANN method. For integrating purpose, the detected PCs pertinent to ore mineralization selected and intruded to neural network structure, as a result different MLPs with various algorithms and structures were produced. The resulting PCANN maps suggest that the gold mineralization and its pathfinder elements (Au, Mo, W, Bi, Sb, Cu, Pb, Ag & As) are associated with metamorphic host rocks intruded by granite bodies in the Alut area. In addition, more concealed and distinct Au anomalies with higher intensity were detected, confirming the privileges of the method in evaluating susceptibility of the area in delineating new hidden potential zones. The proposed method demonstrates simpler network architecture, easy computational implementation, faster training speed, as well as no need to consider any primary assumption about the behavior of data and their probability distribution type, with more satisfactory predicting performance for generating gold potential map of the area. Comparing the results of three methods (PCA, ANN and PCANN), representing the higher efficiency and more

    OBJECTIVE. Urinary tract infections (UTIs) are amongst the most common infections and account for large proportion of antibacterial drug consumption. The aim of this study was to determine the rate and the etiologic agents of UTIs in inhabitants of rehabilitation centers of Mazandaran province in northern Iran and to evaluate the antimicrobial susceptibility patterns of the uropathogens isolated. Clean catch midstream urine sample was collected from each of 314 participants (163 males, 151 females) residing in 12 rehabilitation centers of Ramsar, Nowshahr, Chalous, Amol, Sari and Behshahr. Urine specimens were cultured and bacterial isolates were identified by conventional methods. All urines fulfilling the criteria for the presence of significant bacteriuria (> or = 10(4) cfu/ml urine) were defined as positive. Antibiotic susceptibility testing was performed by Kirby-Bauer disc diffusion method. The rate of urinary tract infection was 30.9% with the highest rate in pediatrics (p 50 years). Bacteria most frequently isolated from urine specimens was Escherichia coli (39.2%) with the highest rate of infection in females age group antibiotics tested against the isolated organisms for susceptibility test, ceftriaxone and gentamicin maintain good activity against the majority of gram negative bacteria that cause UTIs recovered from individuals with intellectual disability. Vancomycin was effective against Staphylococcus aureus. This survey shows that the prevalence of UTIs among inhabitants of institutions for mentally retarded persons in Mazandaran province of Iran is much higher than normal population.

    Full Text Available Data on this paper describe the concentrations of arsenic, cadmium, copper, nickel, lead and zinc in the surface soils and groundwater's of Kiwi gardens and its relation to chemical fertilizers in Amlash city, Guilan Province, in Iran. The results of this study showed that the average concentration of heavy metals in groundwater and soils of the studied areas was less than the national standards of Iran for irrigation water, Dutch MPA for soils (except Cu and Ni and Canadian MAC for inorganic fertilizers. Considering that after fertilizing to soils used in gardening, the concentration of heavy metals in groundwater and soil can be increased significantly, so that chemical fertilizers can be considered as an effective factor in increasing the amount of heavy metals in water and soil. The results of this research can be used by who concern about water and soil quality related to fertilizing and also can be used by Rural Water and Wastewater Company and Ministry of Jahad Agriculture of Iran.

    Full Text Available Background: One of the most common anomalies in newborn infants is cleft lip and/or cleft palate (CL/P. In spite of several studies about the prevalence of this, no investigation evaluated this prevalence in the West and North-West of Iran. With due attention to different ethnic groups in this area, the aim of this study is to investigate whether the distribution of CL/P live births varies regionally in this area of Iran. Materials and Methods: A cross-sectional study was conducted using hospital registry records to identify all children born with CL/P. The hospitals with a maternity unit were selected in the capital cities of four provinces in the West and North-West of Iran, East Azarbaijan, Kurdestan, Gilan, and Markazi. The population under study included all infants born alive from 2008 to 2012. Results: During the study period, 107,317 live births were registered in the hospitals with a maternity unit of four cities, and 52 infants (0.485/1000 live births were born with CL/P. The prevalence in Rasht, Arak, Sanandaj, and Tabriz cities was 0.557, 0.352, 0.503, and 0.559/1000 live births, respectively (P 0.05, whereas the prevalence of CL/P based on sex was statistically different among the four provinces (P < 0.05. Conclusion: This study shows regional variations in the birth prevalence of clefts and various cleft types. The different effects of gender on the birth prevalence of CL/P from city-to-city may be explained environmentally and/or by genetic factors affecting the development of oral clefts.

    In the past half-century, petroleum mulching-biological fixation (PM-BF) practices have been employed to stabilize sand dunes in Iran. However, the effects of PM-BF practices on the attributes of sand dunes and the dispersion of heavy metals of mulch have been poorly understood. To this end, three regions treated with PM-BF for 5, 20, and 40 years and a control region with no PM-BF were studied. Samples of soil properties were taken at the depths of 0-10 cm and 10-50 cm, with three replications, in Khuzestan Province. The results showed that PM-BF practices promoted the restoration of vegetation cover in the sand dunes. In addition, these practices increased the deposition of dust particles, gradually increasing the magnitudes of palygorskite and smectite clays over time. The interactions between dust deposition and PM-BF practices significantly altered the chemical and physical properties of the dunes. PM-BF practices increased soil organic matter (184-287%), cation exchangeable capacity (142-209%), electrical conductivity (144-493%), clay content (134-196%), and penetration resistance (107-170%) compared to the region with no PM-BF practices. Furthermore, petroleum mulching significantly increased the amount of Ni (1.19%), Cd (1.55%), Pb (1.08%), Cu (1.34%), Zn (1.38%), Mn (1.66%), and Fe (1.15%). However, in the long term, these elements will probably leach linearly as a consequence of an increase in organic matter and soil salinity in the light texture of sand dunes.

    Wind erosion risk (WER) for soils of each municipality in the southwest (SW) of Buenos Aires Province (10,491,172 ha) was determined using the wind erosion equation (WEQ) model. WER results from multiplying the soil erodibility index (" I") of the soil by the climatic factor ( C). WER (Mg ha -1 year -1) of each municipality was: Bahía Blanca: 22.4, Coronel Dorrego: 18.6, Coronel Pringles: 4.5, Coronel Rosales: 48.2, Coronel Suárez: 4.5, Guaminí: 3.0, Patagones: 104.6, Puan: 12.2, Saavedra: 3.0, Tornquist: 6.8, and Villarino: 31.7. The maximum weighted average of " I" (Mg ha -1 year -1) corresponded to Coronel Rosales (87.6), Patagones (87.2), Villarino (85.7), Puan (67.9); Guaminí (59.6), Coronel Dorrego (53.1), and Bahía Blanca (39.3); the remaining municipalities ranged between 34.9 and 32.1 Mg ha -1 year -1. The highest C (%) corresponded to Patagones (120), Bahía Blanca (57), Coronel Rosales (55), Villarino (37), Coronel Dorrego (35), Tornquist (21), and Puan (18); for the remaining municipalities it was 14%. The productivity index (PI) is known to establish a numerical value of the productive capacity of lands. The relationship between WER and PI, weighted averages, in all the studied municipalities was fitted by means of a linear model, WER (Mg ha -1 year -1) = 95.23 - 2.09 * PI (%) ( R2 = 66%), and a second-order polynomial model, WER (Mg ha -1 year -1) = 139.41 - 5.86 * PI (%) + 0.07 * PI 2 (%) ( R2 = 74%). No statistically significant relationship was found between WER and PI for each municipality.

    Full Text Available OBJECTIVES: The target of the Fourth Millennium Development Goal (MDG-4 is to reduce the rate of under-five mortality by two-thirds between 1990 and 2015. Despite substantial progress towards achieving the target of the MDG-4 in Iran at the national level, differences at the sub-national levels should be taken into consideration. METHODS: The under-five mortality data available from the Deputy of Public Health, Kermanshah University of Medical Sciences, was used in order to perform a time series analysis of the monthly under-five mortality rate (U5MR from 2005 to 2012 in Kermanshah province in the west of Iran. After primary analysis, a seasonal auto-regressive integrated moving average model was chosen as the best fitting model based on model selection criteria. RESULTS: The model was assessed and proved to be adequate in describing variations in the data. However, the unexpected presence of a stochastic increasing trend and a seasonal component with a periodicity of six months in the fitted model are very likely to be consequences of poor quality of data collection and reporting systems. CONCLUSIONS: The present work is the first attempt at time series modeling of the U5MR in Iran, and reveals that improvement of under-five mortality data collection in health facilities and their corresponding systems is a major challenge to fully achieving the MGD-4 in Iran. Studies similar to the present work can enhance the understanding of the invisible patterns in U5MR, monitor progress towards the MGD-4, and predict the impact of future variations on the U5MR.

    Full Text Available Background Nitrogen dioxide (NO2 is a corrosive, strong oxidant and a physiologic stimulant of lower respiratory tract. Every human being inhales an average of 10-m3 air per day; therefore, assessment of the effect of inhaled air on health is a vital issue. The main source NO2 in urban regions is intra-urban public transport system. The annual average of determined air quality for NO2 is 40 μg/m3. Objectives The present study aimed to estimate and compare epidemiologic indices attributed to the pollutant NO2 in the urban air of southwest cities of Iran, namely, Ahvaz, Kermanshah, and Bushehr, in 2011. Materials and Methods In the present study, data relevant to the air-pollutant NO2 in 2011 was obtained from the Iranian Department of Environment and meteorological organizations of the studied cities. Raw data processing by Excel software included instruction set correction of averaging, coding, and filtering. Then the meteorological parameters were converted as input file to the Air Q model. Finally, by using epidemiologic formulas, relative risk (RR and attributed part to NO2 in the three studied cites were estimated. Results The results showed that in summer, winter, and the whole year, Kermanshah and Bushehr had on average the maximum and minimum NO2 concentration, respectively, in 2011. In addition, accumulative number of cases attributed to exposure with NO2 in the studied cities was maximum in Kermanshah (21 cases and minimum in Bushehr (one case. The results revealed that approximately, the maximum number of death cases attributed to NO2 were observed in Kermanshah due to heart problems (1.06%, acute infarction (1.8%, and obstructive pulmonary disease (1.9% with concentration > 20 μg/m3.

    This study was conducted to investigate the prevalence of subclinical mastitis caused by Staphylococcus spp. in ewes in West-Azerbaijan province of Iran. Molecular characterization of isolated Staphylococcus spp. from diseased ewes were performed using polymerase chain reaction (PCR) followed by restriction fragment length polymorphism (RFLP) and DNA sequencing of glyceraldehyde-3-phosphate dehydrogenase (gap) gene. Also, antibiotic resistance of staphylococcal isolates against different antibiotics was investigated. A total number of 900 milk samples from 450 native ewes in their mid-lactation period were examined by the California mastitis test (CMT). The CMT positive samples were cultured and bacteria were isolated from 86 (9.50%) glands and 74 (16.40%) ewes. The prevalence of subclinical mastitis in the examined ewes was 16.40%. Microbiological analysis of milk samples revealed that 27 out of 74 sheep with subclinical mastitis were infected with Staphylococcus spp. Amplification of gap gene of 27 Staphylococcus isolates generated a single amplicon of 933 bp in size confirming that isolates were belonged to Staphylococcus genus. Digestion of PCR products by AluI endonuclease generated different RFLP patterns for each species. Nucleotide sequencing of gap gene followed by phylogenetic analysis showed that the most dominant Staphylococcus species were S. epidermidis, S. xylosus and S. chromogenes. Staphylococcal isolates showed the highest resistance to penicillin and ampicillin. In conclusion, Staphylococcus species, except for the southern parts of the province, play an important role in the development of subclinical mastitis in sheep in West-Azerbaijan province of Iran. Also, chloramphenicol, ciprofloxacin and neomycin are the most effective antibiotics for treatment of this disease. PMID:27482361

    over an area of 0.8 km2 with 2.3 % and 5.06% ilmenite in Upper Jogaz Valley upstream and downstream consequently. The study of heavy minerals shows that ilmenite is the main heavy mineral in the Upper Jogaz Valley sediments with 120µ to 3 mm, semi-angular to rounded grains with weak sorting. Titanomagnetite, rutile and sphene are present as accessory minerals. Pentlandite, magnetite, chalchopyrite and millerite are also observed as intergrowths or inclusions in ilmenite. Conclusions The investigation of ilmenite concentration in fluvial sediments of the Upper Jogaz deposit represents a gradual increase of ilmenite concentration away from the source rock. Titanomagnetite, sphene and rutile have similar enrichment patterns to ilmenite. This suggests that all Ti-bearing minerals had a similar behavior in the Upper Jogaz Valley fluvial system. The geological and petrographic evidence suggests that the origin of the Upper Jogaz Valley placer is the weatherlng of the Ti-rich gabbros. The higher concentration of ilmenite in the lower part of the valley is probably caused by the lower water energy and flow downstream. The mechanisms of hydraulic sorting (Slingerland and Smith, 1986, such as free settling of grains, entrainment of grains from a granular bed load by flowing water and shear sorting of grains in a moving fluidized bed were important in the enrichment of titaniferous placers in the downstream sediments.

    Full Text Available Objective: To detect and characterize Escherichia coli (E. coli O157:H7 in feral pigeons in Qom province, Iran. Methods: In this survey, 290 cloacal samples were obtained from trapped feral pigeons in Qom province. Microbiological, biochemical and serological examinations were done to detect the E. coli O157:H7. Isolates were subjected to multiplex polymerase chain reaction for the detection of stx1, stx2, eaeA and hlyA genes. Results: Four samples (1.38% were positive for E. coli O157:H7 by using O157 and H7 antisera and only one E. coli O157:H7 strain isolated showed the presence of stx1, stx2, eaeA and hlyA genes. Conclusions: The results of present survey revealed that feral pigeons in Qom province had the potential to be a reservoir of E. coli O157:H7. The low prevalence of E. coli O157:H7 can be attributed to sampling each pigeon just once and fecal culture limits, and true prevalence of the E. coli O157:H7 might be higher than our findings.

    The main goal of this study is to lay out the map of the soil radionuclide activity concentrations and the terrestrial outdoor gamma dose rates in the western Mazandaran Province of Iran, and to present an evaluation scheme. Mazandaran Province was selected due to its special geographical characteristics, high population density and the long terrestrial and aquatic borders with the neighbouring countries possessing nuclear facilities. A total of 54 topsoil samples were collected, ranging from the Nour to Ramsar regions, and were based on geological conditions, vegetation coverage and the sampling standards outlined by the International Atomic Energy Agency. The excess lifetime cancer risks (ELCRs) were evaluated and the coordinates of sampling locations were determined by the global positioning system. The average terrestrial outdoor gamma dose rate was 612.38 ± 3707.93 nGy h(-1), at 1 m above the ground. The annual effective gamma dose at the western part of Mazandaran Province was 750 μSv, and the ELCR was 0.26 × 10(-2). Soil samples were analysed by gamma spectrometry with a high-purity germanium detector. The average (226)Ra, (232)Th, (40)K and (137)Cs activities were 1188.50 ± 7838.40, 64.92 ± 162.26, 545.10 ± 139.42 and 10.41 ± 7.86 Bq kg(-1), respectively. The average soil radionuclide concentrations at the western part of Mazandaran Province were higher than the worldwide range. The excess lifetime risks of cancer and the annual effective gamma doses were also higher than the global average.

    Full Text Available The Hypogastruridae family belonging to the class Collembola (Springtails are among the most important and abundant soil arthropods. These animals play important roles in decomposition processes and nutrient cycling. However, their fauna have remained too much unknown in Iran. In order to study of Collembola fauna in the Mazandaran province, some sampling from soil, leaf litters and mosses were made from different regions of the province during 2012-2013 years. Then, the springtails of samples were separated using Berlese funnel and preserved in 75-85 % ethyl alcohol. During the investigation, some samples belonging to Hypogastruridae were collected and identified. The genus Schoettella and the three species S. unungiuculata, Hypogastrura purpurescens and Ceratophysella engadinensis are new records for fauna of Iran and the two species Xenylla maritima and C. stercoraria are recorded for the first time from Mazandaran province. In addition, an identification key for local genera and species of the family Hypogastruridae in Mazandaran is presented here.

    We used pitfall trapping to investigate the effects of elevation, plant density and soil structure on species diversity and the impact of these habitat factors on lizard habitat selectivity in the Qom Province in the Central Plateau of Iran. From a total of 12 1-ha plots, we captured 363 individuals of 15 species of lizards (six species of Lacertidae, five species of Agamidae, two species of Gekkonidae, one species of Varanidae and one species of Scincidae). A generalized linear model (GLM) determined that elevation was the most important factor impacting species diversity. The highest species diversity was at the intermediate elevation (1289 m). Abundance of 6 out of 15 species showed strong relationships with some habitat factors. These relationships were demonstrated by habitat selectivity index (Ivlev's index). Our result supports other surveys that showed that elevation plays an important role in determining lizard species diversity. PMID:24349557

  1. Mantle amphibole control on arc and within-plate chemical signatures: Quaternary lavas from Kurdistan Province, Iran

    New analyses of Quaternary lavas from Kurdistan Province in west Iran shed light on the nature of collision zone magmatism. The rocks are from the Turkish-Iranian plateau within the Arabia-Eurasia collision. Compositions are typically basanite, hawaiite and alkali basalt. Sr-Nd isotope values are close to BSE, which is similar to Quaternary alkali basalts of NW Iran, but distinct from a depleted source melting under Mount Ararat. The chemical signatures suggests variable melting of two distinct sources. One inferred source produced melts with La/Nb from~3.5 to~1.2, which we model as the result of depletion of amphibole during ≤1% melting in the garnet stability field. We infer phlogopite in the source of potassic lavas from Takab. Lithosphere delamination or slab break-off mechanisms for triggering melting are problematic, as the lithosphere is~150-200km thick. It is possible that the negative dT/dP section of the amphibole peridotite solidus was crossed as a result of lithospheric thickening in the collision zone. This explanation is conditional upon the mantle source being weakly hydrated and so only containing a small proportion of amphibole, which can be exhausted during small degrees of partial melting. Our model maybe viable for other magmatic areas within orogenic plateaux, e.g. northern Tibet. Depletion of mantle amphibole may also help explain larger scale transitions from arc to within-plate chemistry in orogens, such as the Palaeogene Arabia-Eurasia system.

    The long term forecasting and monitoring of climatological parameters depends on identification of all effective factors, which are affects on this phenomena. One of these parameters is the weather signal. These signals are determinable and specific pattern and occurs in the distinguished regions in the world, but it's effects are world wide. One of the famous signals is ENSO phenomenon, which have two phases. In this paper with using annual and seasonal correlations between southern oscillation index (SOI) and precipitation and temperature data the effective amounts of ENSO phases on the differences of these factors was studied in the all regions of Khorasan province in Iran, then for more comprehensive study the classification maps in relation of ENSO and variability of precipitation and temperature were drown. It was concluded that the mentioned parameters in the whole of the province especially in central and north strip have shown significant action to ENSO, in other word the average of precipitation and temperature correlation indices are negative annually and seasonally, it means when SOI amounts are increased the precipitation and temperature in Khorasan will be decreased. With regard to increasing the above weather parameters in all regions of Khorasan at the time of ENSO negative phases (El Nino condition) variations of precipitation and temperature could be related to the changes of the pattern of occurrence this phenomenon (ENSO) due to climatic change around the world.

    The present study examines some heavy metals (As, Cd, Co, Cr, Cu, Ni, Pb and Zn) contents in urban soils of 23 cities in Isfahan province, central Iran. For this purpose, 83 topsoil samples were collected and analyzed by ICP-MS. Results showed that the concentrations of As, Cd, Cu, Pb and Zn are higher than background values, while Co, Cr and Ni concentrations are close to the background. Compared with heavy metal concentrations in selected cities around the world, As, Cd, Cu, Pb and Zn concentrations in urban soils of Isfahan are relatively enriched. Moreover, natural background concentrations of Co, Cr and Ni in Isfahan province soil are high and the apparent enrichment relative to other major cities of the world is due to this high background contents. Calculated contamination factor (CF) confirmed that As, Cd, Cu, Pb and Zn are extremely enriched in the urban soils. Furthermore, pollution load index (PLI) and Geoaccumulation index (Igeo) highlighted that highly contaminated cities are mostly affected by pollution from traffic, industries and Shahkuh Pb-Zn mine. Based on hazard quotients (HQ), hazard index (HI) and cancer risk (CR) calculated in this study, human health risk (particularly for Pb and Cd) have reached alarming scales. Results from principle component analysis (PCA) and positive matrix factorization (PMF) introduces three sources for soils heavy metals including mine and industries (mainly for Pb, Zn, Cd and As); urban activities (particularly for Cu, Pb and Zn); and geogenic source (Ni, Co and Cr).

    Full Text Available Antibiotic residues in milk have a potential hazard for the consumer and may cause allergic reactions, interference in the intestinal flora that result in development of resistant populations of bacteria, thereby rendering antibiotic treatment ineffective. The aim of this study was to determine neomycin residues in pasteurized milk in East-Azarbaijan province. For this, a total of 200 samples of pasteurized milk produced by five dairy processing establishments of East Azarbaijan province was randomly collected. The samples were obtained over the spring and autumn (100 samples for each season of 2010. First, antibiotic residues were determined by Copan milk test. Afterwards, the competitive ELISA assay was used for the determination of neomycin concentration in positive samples. Of all samples, neomycin residues were observed in 9 and 13 samples and the mean neomycin residues amount were 43.20 ± 8.10 and 26.63±2.08 µg/L in spring and autumn, respectively. According to the limit of neomycin (1500 µg/l in cow raw milk in Iran, despite all the remaining drugs in pasteurized milk, in any of the samples exceeded level of neomycin was not observed.Based on the results, continuousmonitoringofantibiotic residues inmilk samples is recommended.

    Crimean-Congo hemorrhagic fever (CCHF) is a potentially fatal viral vector-borne zoonosis which has a mortality rate of up to 30% without treatment in humans. CCHF virus is transmitted to humans by ticks, predominantly from the Hyalomma genus. Following the report of two confirmed and one suspected death due to CCHF virus in Kurdistan province of Iran in 2007, this study was undertaken to determine the fauna of hard ticks on domestic ruminants (cattle, sheep, and goats) and their possible infection with CCHF virus using reverse transcription PCR technique. This is the first detection of CCHF virus in ticks from the Kurdistan province of Iran. Overall, 414 ixodid ticks were collected from two districts in this province. They represented four genera from which 10 separate species were identified. The Hyalomma genus was the most abundant tick genus (70%). It was the only genus shown to be infected with the CCHF virus using RT-PCR technique. The number of ticks positive for CCHF virus was 5 out of 90 (5.6%) adult ticks. The three remaining genera (Haemaphysalis, Rhipicephalus, and Dermacentor) were all negative following molecular survey. Four of the five virally-infected ticks were from cattle mainly in the Sanandaj district. We concluded that CCHF virus is present in the Hyalomma ticks on domestic ruminants (cattle) in Kurdistan province of Iran.

    Parvovirus B19, a member of the Erythrovirus genus of Parvoviridae family, causes various clinical illnesses including infectious erythema, arthropathy, hydrops fetalis or congenital anemia, and transient aplastic crises. The B19 virus can be transmitted through respiratory secretions, blood products, and blood transfusion. The aim of this study was to detect the B19 virus in thalassemia patients in Isfahan, Iran. The prevalence of parvovirus B19 infection was compared between thalassemia major patients and healthy subjects. Plasma samples were collected from 30 thalassemia patients from Isfahan, Iran. Thirty patients without any blood complications were considered as the control group. After DNA extraction from the plasma samples, polymerase chain reaction was performed for parvovirus B19 detection. The parvovirus B19-specific nucleotide sequence was detected in 6 patients (20%). None of the samples obtained from the 30 control subjects tested positive for B19. In this study B19-Parvovirus infection were detected in patients with hematologic disorders in comparison with control subjects. Screening of patients with a high risk of parvovirus B19 infection can considerably reduce the incidence and prevalence of B19 infection.

    Full Text Available Background and Objective: Hard ticks (Acari: Ixodidae are one of the most important obligate ectoparasites of vertebrates, belonging to class Arachnida, which transmit a wide range of pathological agents such as viruses, bacteria, and parasites to humans and animals in Iran and around the world. Identifying the distribution of hard ticks in a region is important to monitor their control program, and thereby prevent disease transmission. Materials and Methods: In this cross-sectional descriptive study, sampling was carried out from different parts of the livestock body during four seasons in four geographical directions and five villages of Famenin County, Hamadan Province, Iran, during 2015-2016. The ticks were initially stimulated by using chloroform solution and then separated from domestic ruminants by forceps. The collected ticks were sent to a laboratory, and then their sex and species were identified by using valid diagnostic keys. Results: We studied 800 domestic ruminants, including cattle, sheep, and goats, and found 150 (18.7% cases of infestation. A total of 274 ticks were collected, 259 of which were hard ticks including four genera of Hyalomma, Dermacentor, Repicephlus, and Haemaphysalis. The greatest diversity of species, including Hyalomma scopens (Hy. deteritum, Hyalomma asiaticum, Hyalomma marginatum, and Hyalomma anatolicum belonged to the genus Hyalomma. The frequency rates of Hyalomma, Dermacentor, Rhipicephalus, and Hemaphysalis genera were 73.74%, 15.05%, 10.03%, and 1.15 %, respectively. The highest abundance of ticks was observed in spring (152. Conclusion: The results of this study indicate the diversity of hard ticks in the region and the highest abundance of ticks in spring. Considering the importance of ticks in disease transmission among humans and domestic ruminants, health authorities and respective organizations should take appropriate health measures to control and combat these external parasites.

    Hepatitis B vaccination has been integrated into National Expanded Program on Immunization in Iran since the year 1993 and young adult national vaccination project was done in 2008. So we have three subpopulations with vaccination coverage for hepatitis B and different antibody levels. Consisting of Subpopulation 1 born after 1993, subpopulation 2 born between 1989 and 1993 and receiving vaccination under adult national project, and subpopulation 3 born prior to the year 1989. The present study was conducted to investigate community protection by hepatitis B vaccine in adult population in an accessible population in Iran and compare vaccination coverage, HBs Ab level, and its effective titration among the three above-mentioned subpopulations. This cross-sectional study was done on a 3000-individual adult population from all seven counties of Chaharmahal and Bakhtiari province enrolled by clustering. After obtaining written consent and filling out a questionnaire of demographic data and history of hepatitis B vaccination by trained interviewers, necessary blood sample was taken and HBs Ab titration was checked. The data were analysed by chi-square in SPSS 19. The level of significance was considered as 0.05 and effective Ab titration as ≥ 10. The mean age of the participants was 38.4±16.3 years. Of the participants 48.2% had effective titration. For vaccination coverage, 77.4% were unvaccinated, 20% completely vaccinated, and 2.6% incompletely vaccinated with a significant association with effective titration (ptitration between them (ptitration was significantly associated with being married and residence place (p=0.003). There was a significant association between effective titration and the time at vaccination (p<0.001). Protection provided by hepatitis B vaccine in adult population is relatively suitable especially in the youth population; however, catch-up programs of the groups exposed to risk are recommended.

    Full Text Available Background: The Qashqa’i form approximately 500000 Turkish-speaking ethnic nomadic pastoralist tribal people, living in Fars province, southern Iran. People choosing macrobiotic diets are frequently identified as following a vegetarian diet. Despite that plant foods contain only non-heme iron, which is more sensitive than heme iron to both inhibitors and enhancers of iron absorption, surprisingly, we noted that the mean values of hemoglobin and serum ferritin in the group under investigation were significantly higher than the same population living in the south of Iran. So we aimed to investigate the food basket of Qashqa’I people in an attempt to find out the reason behind this observation. Methods: Dietary information was collected using the mean of 3-day recall and food frequency methods. Dieticians, with long experience in nutrition surveillance explained the purpose of the dietary information and instructed the girls on how to report quantities using food basket. Iranian food processor was used to enter and analyze nutrient intakes. Weig hts and heights were measured using established equipment and techniques and body mass index(BMI values were calculated. Results: Mean value of hemoglobin was 12.31±1.51 gr/dL, ferritin 23.59±4.2 μg/L, albumin 4.27±1.1 gr/dL, and total protein 7.72±1.3 gr/dL. BMI of 81% of the women was between 18.5 and 25 kg/m2. Conclusion: The mean serum albumin, total protein, hemoglobin, and serum ferritin of this population show that vegetarian diet can meet protein and Iron requirements by using the variety of plant foods.

    Full Text Available Background: Internal corrosion and the formation of scale in water distribution pipes are the most important problems for an urban water distribution system. Physical, chemical, or biological factors can lead to these two processes. Internal corrosion and scale formation can impact health, economy, and aesthetics. This study assessed the physicochemical quality parameters and evaluated the potential for corrosion and scale formation in drinking water at the distribution systems of 5 selected cities in Bushehr province (Kangan, Dashtestan, Dashti, Bushehr, and Ganaveh from 2009-2012. Methods: This study was carried out based on laboratory data collected from monthly samplings of tap water in the Water and Wastewater Company of Bushehr province during the years 2009-2012. Internal corrosion and scale formation rates were calculated using the Ryznar, Langelier, Aggressive, and Puckorius indices. Results: The results of the Ryznar, Puckorius, Aggressive and Langelier indices indicated that the drinking water in the 5 selected cities of Bushehr province was corrosive. Moreover, the majority of parameters used to determine water quality exceeded Iran’s national standards. Conclusion: It is concluded that there is problem of water corrosion and scaling in drinking water of distribution systems in selected cities.

    Full Text Available Floristic study of a region is of great importance as the list of plants represents the genetic resources of the area. The intended region (Jozak-Chaminbid with an area of ca. 3637.81 ha. is located in the western part of North Khorassan Province in the Maneh and Semelghan counties. Phytogeographically, this region is located in Khorassan-Kopet Dagh floristic province of the Irano-Turanian region. The mean altitude is 1415 meter and mean annual precipitation of the area is 559 mm. The plant species of the area were collected and identified according to the Floras. The floristic list of the area and its life forms and endemic species were presented. The results showed the presence of 53 families, 205 genera and 308 species. Among them 13 species were endemic to Khorassan-Kopet Dagh Province. The largest plant family was Asteraceae with 28 genera and 40 species. According to Raunkiaer’s life form categories, the identified species are categorized as hemicryptophytes 35.38%, therophytes 34.74%, cryptophytes (geophytes 12.33%, chamaephytes 11.03% and phanerophytes 6.49%. The high percentage of hemicryptophytes indicated that the area had a cold mountain climate. The chorotype of species was obtained on the basis of the available sources. Irano-Turanian plants were the most frequent chorotype of the area with 59%.

    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. 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. Of 123 children referred for examination, 27 children were confirmed to have severe visual impairment/blindness or blindness. The median age was11 years (interquartile range 6-13), and 59% were girls. After adjusting for non-attenders, the estimated prevalence of severe visual impairment/blindness was 0.04% (0.03-0.05). The main site of abnormality was retina (44%), followed by disorders of the whole eye (33%). The majority of causes had a hereditary etiology (70%), which was associated with a family history of blindness (P = 0.002). Potentially avoidable causes of severe visual impairment/blindness were found in 14 children (52%). Almost all children with severe visual impairment/blindness had a history of parental consanguinity (93%). Our findings suggest a moderate prevalence of childhood blindness in the Lorestan province of Iran, a high proportion of which may be avoidable, given improved access to ophthalmic and genetic counselling services in rural areas. The Key Informant Method is feasible in Iran; future research is discussed.

    Although considerable progress has been made in the past years in management of mosquito borne diseases such as malaria, dengue, yellow fever and West Nile fever through research in biology and ecology of the vectors, these diseases are still major threats to human health. Therefore, more research is required for better management of the diseases. This investigation provides information on the composition, co-occurrence, association and affinity indices of mosquito larvae in Mazandaran Province, northern Iran. In a large scale field study, mosquito larvae were collected from 120 sentinel sites in 16 counties in Mazandaran Province, using standard 350 ml dipper. Sampling took place monthly from May to December 2014. Collected larvae were mounted on glass slides using de Faure's medium and were diagnosed using morphological characters. Totally, 19,840 larvae were collected including three genera and 16 species from 120 larval habitats, as follows: Anopheles claviger, Anopheles hyrcanus, Anopheles maculipennis s.l., Anopheles marteri, Anopheles plumbeus, Anopheles pseudopictus, Culex pipiens, Culex tritaeniorhynchus, Culex torrentium, Culex perexiguus, Culex territans, Culex mimeticus, Culex hortensis, Culiseta annulata, Culiseta longiareolata, and Culiseta morsitans. Predominant species were Cx. pipiens and An. maculipennis s.l. which show the highest co-occurrence. The pair of species An. hyrcanus/An. pseudopictus showed significant affinity and association. High co-occurrence of the predominant species Cx. pipiens and An. maculipennis s.l. in the study area is of considerable importance in terms of vector ecology. It was also revealed that An. pseudopictus/An. hyrcanus often occur sympatrically indicating their common habitat requirements. The information may be equally important when vector control measures are considered. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available This study aims at investigating the use of critical thinking in high school social science textbooks based on Fars Province teachers' attitudes in order to present a model for textbook development. To achieve this goal, the use of the following skills in the social science textbooks was analyzed: reasoning, questioning, assessment of examples and statements, group work, interpretation, true judgment about issues, analysis and evaluation, logicality, and explicitness. It is a field study which was conducted in several high schools of Fars Province in Iran. The population of this study included 568 social science teachers. The sample was selected based on the stratified random sampling procedure so that 153 teachers participated in this study. The data were collected using a forty-four-item questionnaire based on Likert-scale, which was developed and validated by the researcher himself and some experts. The reliability coefficient was also estimated as 0.86. The data were analyzed through descriptive statistics (frequency, percentage, standard deviation, and coefficient of variations and inferential statistics (Chi-square and Kruskal-Wallis Non-parametric tests. The result showed that the teachers of the Social Studies Textbook evaluated assessment of examples and statements, and analysis and evaluation skills as not satisfactory respectively. They evaluated the other skills as fairly satisfactory. Teachers of Sociology Textbook 1 evaluated explicitness, assessment of examples and statements, analysis and evaluation, and interpretation skills as not satisfactory respectively. They also evaluated other skills as fairly satisfactory. Teachers of Sociology Textbook 2 evaluated explicitness as not satisfactory, logicality as satisfactory, and other skills as fairly satisfactory. Therefore it is possible to rank order the social science textbooks of high school as satisfactory and not satisfactory with regard to the use of critical thinking. In other

    This research aims to determine the mental health status of population aged 15 and over in the province of Golestan in 2015. The statistical population of this cross-sectional field survey consisted of residents of urban and rural areas of Golestan province in Iran. An estimated sample size of 1200 people was chosen using systematic random cluster sampling. The access was provided by the contribution of Geographical Post Office of Gorgan, Gonbad-e-Qabus, and Aqqala cities. The General Health Questionnaire-28 (GHQ-28) was used as the screening tool for mental disorders. The analysis of data in the current study was carried out using the SPSS-18 computer software. Using GHQ traditional scoring method, the results showed that 12.8% of the subjects showed to be at risk of mental disorders (13.3% of females and 12.3% of males). Urban areas (13%) were more at risk of mental disorders compared with rural residents (12.3%). Anxiety and somatization symptoms were more frequent than depression and social dysfunction among respondents. The obtained data revealed that the prevalence of mental disorders increased with age. The results also indicated that mental disorders were more common in certain subgroups, in particular women, those aged 65 years and above, the divorced and widowed, illiterate and retired adults. Our findings suggest that one eighth of the participants were at risk of developing mental disorders. Although the prevalence of these disorders has decreased from 39.1% to 12.8% between 1999 and 2015, it is still of great importance to further promote mental health policies and advocate psychological welfare of those suffering from mental disorders along with their re-empowerment.

    Based on some estimation more than two million peoples in Iran are affected by Type 2 diabetes. The present study was designed to evaluate the status of diabetes control among Type 2 diabetes patients in Kurdistan, west of Iran and its associated factors. In our cross sectional study conducted in 2010, 411 Type 2 diabetes patients were randomly recruited from Sanandaj, Capital of Kurdistan. Chi square test was used in univariate analysis to address the association between HgAlc and FBS status and other variables. The significant results from Univariate analysis were entered in multivariate analysis and multinomial logistic regression model. In 38% of patients, FBS was in normal range (70-130) and in 47% HgA1c was <7% which is normal range for HgA1c. In univariate analysis, FBS level was associated with educational levels (P=0.001), referral style (P=0.001), referral time (P=0.009), and insulin injection (P=0.016). In addition, HgA1c had a relationship with sex (P=0.023), age (P=0.035), education (P=0.001), referral style (P=0.001), and insulin injection (P=0.008). After using multinomial logistic regression for significant results of univariate analysis, it was found that FBS was significantly associated with referral style. In addition HgA1c was significantly associated with referral style and Insulin injection. Although some of patients were under the coverage of specialized cares, but their diabetes were not properly controlled.

    Full Text Available Introduction Hornblende-bearing gabbroic rocks are quite common in subduction-related magmatic suites and considered to represent magmatic differentiation process in arc magmas (Heliker, 1995; Hickey-Vargas et al., 1995; Mandal and Ray, 2012. The presence of hornblende as an important mineral phase in gabbroic rocks of subduction zone has been considered either as an early crystallizing mineral from water-bearing mafic magmas (Beard and Borgia 1989; Mandal and Ray, 2012 or as a product of reaction of early crystallized minerals (olivine, pyroxene and plagioclase and water-rich evolved melt/aqueous fluid (Costa et al., 2002; Mandal and Ray, 2012. The careful study of petrology and geochemistry of hornblende-bearing gabbroic rocks from Chahak area, of Neoproterozoic age, can provide important information about their petrogenesis. Because of the special characteristics of Chahak hornblende gabbros according to their age and their situation in the main structural units of Iran, their study can present critical keys for the knowledge of geological history of Iran specially central Iran zone. Material and Methods This study carried out in two parts including field and laboratory works. Sampling and structural studies were carried out during field work. Geological map for the study area was also prepared. 65 thin and polished thin sections for petrographical purpose were studied. Major oxides, rare earth elements and trace elements were analyzed for 4 samples (92P-1, 92P-3, B1and B6 from hornblende gabbros on the basis of 4AB1 method using ICP-MS of ACME Laboratory from Canada. In addition, major oxides of three hornblende gabbro samples (89P-62, 89P-59 and 89P-46 were used from Partovifar (Partovifar, 2012. Results and discussion Fariman metamorphic terrains, of Proterozoic age, consist of metamorphosed sedimentary and igneous (plutonic and volcanic rocks. Hornblende gabbros of the study area include plagioclase, hornblende, biotite pyroxene and

    Full Text Available Introduction Iron is among the metals whose ore deposits are not confined to a specific geologic period of crustal formation and they have formed in various geologic environments during previous periods (Ghorbani, 2007. About 95% of iron ore deposits have sedimentary origin and have formed due to chemical deposition from ancient sea water. The remaining percent is the result of alteration and magmatic activities (Gutzmer and Beukes, 2009. In sedimentary environments, a large amount of sedimentary iron minerals have formed resulting in different iron facies. Iron oxide facies are of the most important facies (James, 1954. The most important Iranian iron deposits are located in Central Iran, Sanandaj- Sirjan and East Iran zones, and the Kordestan area (Ghorbani, 2007. In the Orumiyeh-Dokhtar Zone, many iron ore deposits have been formed in conjunction with granitic and granodioritic plutons related to Oligocene-Miocene plutonic and volcanic activities (Hoshmandzadeh, 1995. The Mamouniyeh iron ore-terra rossa deposit is located in the Orumiyeh-Dokhtar volcanic zone. Iron mineralization have occurred in trachytic-trachyandesitic lavas and pyroclastic rocks of Pliocene age. Materials and methods A total of 28 rock samples were picked up from ore and host rocks during field observations. Petrographical and mineralogical studies were performed on 15 thin sections of ore and host rocks. XRD studies were performed on 3 ore samples. In order to investigate the geochemistry of the ore, 10 samples were analyzed for major, trace and rare earth elements (REEs using the ICP-MS method. Result Field and mineralogical studies reveal that the ore is composed of hematite along with crypto-crystalline silica as alternating layers of various thickness and color. The existence of alternating layers of hematite and quartz implies that the ore is similar to banded iron formations, but on a smaller scale, related to submarine hydrothermal activities. Silica is found as

    Full Text Available Objective: To get new data about the ecology of mosquitoes, which would be valuable to develop programs for future provision of mosquito controls in the study area. Methods: During April to September 2012, larvae of mosquitoes were collected from six counties in south of Fars Province using dipping method. Characteristics of larval breeding places were considered based on water conditions. Species diversity was examined in terms of alpha and beta measures, with the intent of comparing mosquito diversity according to the typology of regions. Results: During this investigation, totally, 5 057 larvae of mosquitoes belonging to 5 genera and 17 different mosquito species were recognized, namely, Anopheles dthali, Anopheles fluviatilis, Anopheles stephensi, Anopheles superpictus, Culex quinquefasciatus (Cx. quinquefasciatus, Culex mimeticus, Culex perexiguus, Culex pipiens (Cx. pipiens, Culex tritaeniorhynchus, Culex theileri (Cx. theileri, Culex tritaeniorhynchus, Culex sinaiticus, Culex torrentium, Culex modestus, Ochlerotatus caspius, Culiseta longiareolata and Aedes vexans (Ae. vexans. This is the first record of Ae. vexans, Culex perexiguus and Culex modestus in the Province. Cx. pipiens (27.3%, Cx. theileri (15.9% and Cx. quinquefasciatus (9.4% were the most abundant species found respectively. Cx. pipiens reached the highest density in August and July, while Cx. theileri, Cx. quinquefasciatus and Ae. vexans were found in high numbers in June. Diversity analysis indicated the highest species diversity in the Mohr County (Margalef index of 1.41 and Shannon index of 1.7 and the lowest species diversity in the Lamerd County (Margalef index of 0.33 and Shannon index of 0.38. Conclusions: Regarding to this research, there are some potential vectors of medical and veterinary importance in Fars Province. Results of the present study may serve as a basis for risk assessment of emerging mosquito-borne diseases.

    The evaluation of a hazardous waste disposal site is a complicated process because it requires data from diverse social and environmental fields. These data often involve processing of a significant amount of spatial information which can be used by GIS as an important tool for land use suitability analysis. This paper presents a multi-criteria decision analysis alongside with a geospatial analysis for the selection of hazardous waste landfill sites in Kurdistan Province, western Iran. The study employs a two-stage analysis to provide a spatial decision support system for hazardous waste management in a typically under developed region. The purpose of GIS was to perform an initial screening process to eliminate unsuitable land followed by utilization of a multi-criteria decision analysis (MCDA) to identify the most suitable sites using the information provided by the regional experts with reference to new chosen criteria. Using 21 exclusionary criteria, as input layers, masked maps were prepared. Creating various intermediate or analysis map layers a final overlay map was obtained representing areas for hazardous waste landfill sites. In order to evaluate different landfill sites produced by the overlaying a landfill suitability index system was developed representing cumulative effects of relative importance (weights) and suitability values of 14 non-exclusionary criteria including several criteria resulting from field observation. Using this suitability index 15 different sites were visited and based on the numerical evaluation provided by MCDA most suitable sites were determined.

    The surveillance of acute flaccid paralysis (AFP) is a key strategy for monitoring the progress of poliomyelitis eradication and is a sensitive measure for detecting potential cases of poliomyelitis and poliovirus infection. This study was conducted to describe the characteristics of patients reported with AFP, and to evaluate the performance of the surveillance system in Kurdistan province, western Iran, using indicators recommended by the World Health Organization (WHO). This observational study was conducted from January 2000 to December 2010 at the Kurdistan Center for Disease Control and the Department of Pediatrics. All children who fulfilled the WHO definition for AFP were included in our study. The stool samples of all the children were sent for poliovirus isolation. All the patients were evaluated for 60 days after the onset of symptoms to identify the signs of residual weakness. One-hundred thirty nine children aged Kurdistan during the study period, we achieved the WHO target for AFP surveillance. All performance indicators but one consistently met the WHO requirements and therefore demonstrated the effectiveness of the AFP surveillance program in Kurdistan. The effective surveillance system in Kurdistan and its evaluation may serve as a model for the surveillance of other infectious diseases.

    Food allergy refers to abnormal reactions of the body caused by an immune system response to food. This study was conducted aiming to investigate allergy to food allergens in children with food allergies. This study was conducted as a cross-sectional one on 304 children aged six months to seven years with food allergies admitted to the tertiary referral hospital in Kurdistan Province - Iran, during 2014-2015. All the patients were examined for skin prick test using 49 allergens. Finally, the obtained data were analysed using SPSS15 and chi-square and t tests. The highest percentage of occurrence of bump reaction (wheal) and redness (flare) was due to the consumption of fish, eggs, tomatoes, and cocoa. Moreover, the lowest rate of wheal and flare was caused by exposure to allergens like latex, tea, malt, and wheat flour. The reaction most created due to the consumption of foods was flare which was higher among under three-year-olds group (p<0.05), and between the sexes, girls showed the most common allergic reactions (p<0.05). Since food allergy has a high prevalence in children, it should be considered with great interest. Considering that avoiding food allergens is the first step in the treatment of food allergies, the present study may be a useful guide in this regard. Copyright © 2017 SEICAP.

    Full Text Available Background: Visceral leishmaniasis (VL or kala-azar is a parasitic disease caused by the species of Leishmania donovani complex. Mediterranean type of the disease is endemic in some parts of Iran and more than 95% of cases were reported in children up to 12 years of age. This study was performed to determine the seroprevalence of VL in the rural areas of the Dashti district from Bushehr province.Materials and Methods: In this cross-sectional study, a randomized cluster sampling method was used for the collection of blood samples from children up to 12 years old from rural areas of Dashti district. Before sampling; a questionnaire was filled out for each case. All the collected blood samples were examined after the serum separating by Direct Agglutination Test (DAT for detection of anti-Leishmania infantum antibodies. The cutoff titers of ≥1: 3200 with specific clinical features were supposed to be considered as VL.Results: Altogether, 24 out of 1221 (1.96% blood samples showed titers between 1:800 and 1:1600 which considered as suspicious cases. None of the suspicious cases had a history of kala-azar. None of 1221 collected blood samples showed anti Leishmania infantum (L. infantum at titer ≥1:3200.Conclusion: This study confirms the circulation of L. infantum in Dashti district and highlights the sporadic pattern of VL in the studied areas which necessitates the surveillance system to be monitored by health authorities.

    According to the World Health Organization (WHO) reports, Iran is located in the global fluoride belts, so that is why carrying out extended research on this contaminant anion in water supplies must be considered. Due to the various industries in the Ardakan city, this region is severely suffering from fluoride contamination. This study was designed to investigate the fluoride concentration and its distribution pattern as well as related health risk assessment in groundwater resources of 28 villages of the Ardakan city in Yazd province using SPADNS method according to standard instructions. Our results show that, the average concentration of fluoride was 2.92 mg/l (range: 0.9-6 mg/l), also in half of the villages, the concentration range of this element was over than standard level (1.5 mg/l) given by WHO rules. In addition, risk assessment results showed that HQ value is higher than 1 in 46.4% of samples of groundwater resources in age groups of infants, children, teenagers and adults. Therefore, it is necessary to take measures to reduce fluoride concentration in drinking water in order to control resultant fluorosis. Actions should be implemented to enhance monitoring of fluoride levels to avoid the potential risk of high Fluoride concentration.

    This study was conducted to determine the incidence of Pseudomonas aeruginosa infections among burn patients at Tohid Hospital, Iran. A total of 176 clinical specimens were obtained from 145 burn patients admitted to the burn unit of Tohid Hospital to detect the presence of P. aeruginosa. Antimicrobial susceptibility testing was conducted to detect extended spectrum beta-lactamase (ESBL) producing P. aeruginiosa using Clinical and Laboratory Standards Institute guidelines with the double disc synergy test (DDST). A polymerase chain reaction was used to detect PER-1 and OXA-10 among the isolates. The mean age, total body surface area and length of hospital stay among patients were 29 years, 37.7%, and 10 days, respectively. Kerosene was the commonest cause of burn (60%), followed by gas (30%). During the study, P. aeruginosa was detected in 100 isolates. The antibiotics they were most commonly resistant to were cefotaxime, ceftriaxone and ciprofloxacin. Of the 100 P. aeroginusa isolates, 28% were positive for ESBL production with the DDST, 48% and 52% were PER-1 and OXA-10 producers, respectively. The high frequency of PER-1 and OXA-10 producers at this hospital is of concern considering their potential spread among burn patients.

    Full Text Available Background & Aims of the Study: One way to increasing shelf life of meat is the production of sausages along with additives. One of these additives contains nitrite that in an acceptance limit is not a threat for human health but if it's amount is higher than standard, it will react in the body with secondary amine and the result is the formation of carcinogenic nitrosamines. Also, the consumption of healthy and safe food is concerned for every consumer. That's why we decided to examine Nitrite, Carbohydrates, Fat, Protein, Humidity, microbial contamination and exterior features of the sausages which were produced in Qazvin province. Materials and Methods: The study population consisted of sausages produced in Qazvin province from 2011 to 2014. A total of 74 samples of products that have been produced in the factories of meat products of Qazvin, distribution system and retail level were collected. Additive composition, microbial contamination and exterior features were examined according to standard methods of Iranian national standards No 2303. Results: The overall result showed that all products comply with their nitrite acceptance limit. Of course, the amount of humidity (13.84% and carbohydrates (39.62% were infringement but the two combinations no adverse effects on human health and microorganism counts determined in overall processing were not at harmful levels for human health and microbial contamination of all meat products of our study were acceptable. Conclusion: According to the results, we should have more control on the hygienic quality of meat products over the production, storage and supply periods in this area.

    Full Text Available The prevalence of obesity has been increasing in Iran over the past decade. This study aimed to determine the population-attributable fraction (PAF of hypertension associated with obesity, abdominal obesity, and the joint effect of both in the central provinces of Iran. Prevalence of hypertension was extracted from the Iranian Ministry of Health Non-Communicable Disease Risk Factor InfoBase 2009. Measure of association between obesity and hypertension was extracted from Tehran Lipid and Glucose Study, for males and females, in order to calculate the PAF of hypertension associated with obesity. Age standardization of the reported prevalence of obesity was done using the World Health Organization method. The PAF of hypertension associated with the joint effect of obesity and abdominal obesity in females was highest in Semnan Province: 22.7 [95% confidence interval (CI: 4.2–35.6], followed by Qom 21.09 (95% CI: 3.7–33.1, and Yazd 20.3 (95% CI: 3.5–32.1. In males, the highest PAF was observed in Qom Province 31.07 (95% CI: 16.7–41.1, followed by Semnan 29.6 (95% CI: 15.9–39.3, Qazvin 25.9 (95% CI: 13.7–34.5, Tehran 24.2 (95% CI: 12.7–32.3, and Isfahan 20.4 (95% CI: 3.5–27.4. Prevalence of hypertension is higher in more developed provinces. PAFs suggest that a sizable share of hypertension in these provinces is associated with obesity. It is recommended that health promotion programs focus on obesity in the provinces with a higher share of hypertension due to obesity.

    Background: Fascioliasis, caused by Fasciola hepatica and F. gigantica, has medical and economic importance in the world. Molecular approaches comparing traditional methods using for identification and characterization of Fasciola spp. are precise and reliable. The aims of current study were molecular characterization of Fasciola spp. in West Azerbaijan Province, Iran and then comparative analysis of them using GenBank sequences. Methods: A total number of 580 isolates were collected from different hosts in five cities of West Azerbaijan Province, in 2014 from 90 slaughtered cattle (n=50) and sheep (n=40). After morphological identification and DNA extraction, designing specific primer were used to amplification of ITS1, 5.8s and ITS2 regions, 50 samples were conducted to sequence, randomly. Result: Using morphometric characters 99.14% and 0.86% of isolates identified as F. hepatica and F. gigantica, respectively. PCR amplification of 1081 bp fragment and sequencing result showed 100% similarity with F. hepatica in ITS1 (428 bp), 5.8s (158 bp), and ITS2 (366 bp) regions. Sequence comparison among current study sequences and GenBank data showed 98% identity with 11 nucleotide mismatches. However, in phylogenetic tree F. hepatica sequences of West Azerbaijan Province, Iran, were in a close relationship with Iranian, Asian, and African isolates. Conclusions: Only F. hepatica species is distributed among sheep and cattle in West Azerbaijan Province Iran. However, 5 and 6 bp variation in ITS1 and ITS2 regions, respectively, is not enough to separate of Fasciola spp. Therefore, more studies are essential for designing new molecular markers to correct species identification.

The samples were cultured on bacteriological culture media and bacterial species were identified following standard procedures. A structured questionnaire was used to record sociodemographic and behavioral data analysis of the food handlers.Of the total 220 subjects examined, 62.2% showed positive culture for different bacterial species from their fingernail contents, 65.4% were found to be harboring Staphylococcus aureus in their nostrils and 0.9% tested positive for Shigella boydii from stool samples. Staphylococcus aureus was the predominant bacteria isolated from fingernail specimens (46%, followed by Escherichia coli (29.2%, Coliforms (18.2% and Pseudomonas aeruginosa (6.6%. This study showed a statistically significant difference in the rate of bacterial infestation between different occupational categories (p = 0.04. Butchers showed the highest prevalence of bacteria (86.6% in their fingernail contents, followed by fast food workers (76.5%, bakers (73.5%, chicken store workers (73%, school cafeterias staff (53.3%, restaurant workers (46.9% and fruit/vegetables sellers (42.5%. The highest rate of nasal carrier for Staphylococcus aureus was observed among chicken store workers 14/17(20.8%.These findings indicate the need for intensive training/retraining and health education of all food service employees and strengthening the existing screening methods to control the problem of bacterial infestation in food handlers

    Full Text Available Crimean-Congo hemorrhagic fever (CCHF is a viral disease of Buynaviridae family. Disease is primarily zoonosis but sporadic and epidemic human infection can occur. During year 2001 many outbreaks have been reported from Kosovo, Iran, Albania and Pakistan. A Hyalomma tick can transmit the disease and virus reservoirs are rodents, ostrich, ground frequenting birds and hyalomma tick. Another way of human infection is contact with infected animal blood and products or crushing a tick with bare hands. Contact with infected human blood can also transmit the disease. During outbreak, 18 cases were confirmed by serologic methods. 12 men and 6 women aged 20-40 years old. Ten of men and 5 of women had history of contact with infected animal blood or tissue and a lady had been bitten by a tick. A young assistant of internal medicine who came in contact with the first patient, developed the disease. We were not able to determine route of transmission in one case. The most frequent clinical signs included fever, myalgia, weakness, fatique, bleeding tendency, petechia, purpura and jundice. Lab exam revealed thrombocytopenia, elevated liver enzymes and prolongation of prothrombin time. Althoug the most common route of human infection is tick bite, but in this outbreak the main route was contact with infected animal blood and tissue. This point confirms that unsanitary slaughtering of animal could be dangerous. It seems that reeducating physicians, veterinarians and those who take care of such patients maybe helpful to neighboring countries triggered the outbreak, so that educating people who are involved in husbandry may limiting human infection.

    Full Text Available Background and objectives : Congenital hypothyroidism (CH is one of the most prevalent causes of mental retardation which is preventable provided that earlier diagnosis and treatment are performed. The aim of this study was to investigate the prevalence of congenital hypothyroidism among newborns in Azarshahr during 2011. Material and Methods : This cross-sectional study was conducted on 1775 newborns in Azarshahr applying census method. In this regard, four drops of blood samples were taken preferably from each 3-5 day-old newborn’s heel using auto-lancet and then transferred to Whatman® 903 filter papers. Samples were checked to measure TSH level using ELISA method. Results : Program covering percentage was 95.9%. The disease prevalence was 1.12 per 1000 live births or one case per 887 live births. According to the results, 52.4% of the newborns were male. Samples in 84.6% of newborns were taken within 3rd-5th days of life and in 14.8%, within 6th-21st days of life. The TSH level in 97.5% of screened newborns was lower than 5 mu/L and in 1.6% of the samples was within the range of 5-9.9 mu/L. Recall rate was 1.7% and among them, two patients with hypothyroidism were found. The average age of treatment onset in patients was 20.5 days. Conclusion : Because of high prevalence of hypothyroidism in Azarshahr in comparison with other areas of Iran and the world, it is necessary to continue screening program.

    The management of dental solid waste continues to be a major challenge, particularly in most healthcare facilities of the developing world. In Iran, few studies on management of dental solid waste and its composition are available. An effort has been made through this study to evaluate the hazardous and infectious status of dental solid waste, keeping in mind its possible role in cross-infection chain. For this study, 123 private dental centres and 36 public dental centres were selected and the composition and generation rate of dental solid waste produced were measured. Dental solid waste was classified to four main categories: (i) domestic-type; (ii) potentially infectious; (iii) chemical and pharmaceutical; and (iv) toxic, which constituted 11.7, 80.3, 6.3, and 1.7%, respectively, of the total. Also, the results indicated that the dental solid waste per patient per day generation rate for total, domestic-type, potentially infectious, chemical and pharmaceutical, and toxic wastes were 169.9, 8.6, 153.3, 11.2, and 3.3 g/patient/d, respectively. Furthermore, the per day generation rates for total, domestic-type, potentially infectious, chemical and pharmaceutical, and toxic wastes were 194.5, 22.6, 156.1, 12.3, and 3.4 kg/d, respectively. According to findings of this study, for best management of dental waste it is suggested that source reduction, separation, reuse, and recycling programmes be implemented and each section of dental waste be collected and disposed of separately and in accordance with related criteria.

    Full Text Available Intestinal coccidiosis, caused by Eimeria species, is an economically-important disease of poultry production industry worldwide. This study was designed to investigate the prevalence of different Eimeria species in the farmed broilers of Khoy city, West Azarbaijan, North West Iran. A total of 26 broiler farms of different production capacities were arbitrarily selected and examined in 2013. In each of the farms, Litters of two broilers farms were randomly sampled twice a week and examined. The intensity of infection with each of the Eimeria species was assessed on the basis of number of oocysts per gram of litter using Clayton-Lane and McMaster methods. Eimeria species diversity was determined by using oocyst sporulation technique in 2% potassium dichromate solution. Results indicated that 23.08% (6/26 of the broiler farms were infected with Eimeria oocysts. The maximum litter infection rate (7.5×103 was observed in fifth week of the rearing period. The litter infection rate was significantly correlated with kinds of water dispenser, feeder, ventilation, and density. The litters were infected with five Eimeria species; E. maxima (32.67% in 6 farms (23.07%, E. mitis (24% in 6 farms (23.07%, E. acervulina (18% in 5 farms (19.23%, E. tenella (14.67% in 4 farms (15.38%, and E. necatrix (10.67% in 3 farms (11.58%. Results of this study uncovered high rates of litter infection with various Eimeria species in the studied farms, suggesting the establishment of firm health management strategies in the region.

    The Kharapeh gold deposit is located along the northwestern margin of the Sanandaj–Sirjan Zone (SSZ) in the West Azerbaijan province, Iran. It is an epizonal orogenic gold deposit formed within the deformed zone between central Iran and the Arabian plate during the Cretaceous–Tertiary Zagros orogeny. The deposit area is underlain by Cretaceous schist and marble, as well as altered andesite and dacite dikes. Structural analysis indicates that the rocks underwent tight to isoclinal recumbent folding and were subsequently co-axially refolded to upright open folds during a second deformation. Late- to post-tectonic Cenozoic granites and granodiorites occur northeast of the deposit area. Mineralization mainly is recognized within NW-trending extensional structures as veins and breccia zones. Normal faults, intermediate dikes, and quartz veins, oriented subparallel to the axial surface of the Kharapeh antiform, indicate synchronous extension perpendicular to the fold axis during the second folding event. The gold-bearing quartz veins are >1 km in length and average about 6 m in width; breccia zones are 10–50 m in length and ≤1 m in width. Hydrothermal alteration mainly consists of silicification, sulfidation, chloritization, sericitization, and carbonatization. Paragenetic relationships indicate three distinct stages—replacement and silicification, brecciation and fracture filling, and cataclastic brecciation—with the latter two being gold-rich. Fluid inclusion data suggest mineral deposition at temperatures of at least 220–255°C and depths of at least 1.4–1.8 km, from a H2O–CO2±CH4 fluid of relatively high salinity (12–14 wt.% NaCl equiv.), which may reflect metamorphism of passive margin carbonate sequences. Ore fluid δ18O values between about 7‰ and 9‰ suggest no significant meteoric water input, despite gold deposition in a relatively shallow epizonal environment. Similarities to other deposits in the SSZ suggest that the deposit formed as

    Abstract Colorectal cancer (CRC) survival varies at individual and geographically level. This population-based study aimed to evaluating various factors affecting the survival rate of CRC patients in Kurdistan province. In a retrospective cohort study, patients diagnosed as CRC were collected through a population-based study from March 1, 2009 to 2014. The data were collected from Kurdistan's Cancer Registry database. Additional information and missing data were collected reference to patients’ homes, medical records, and pathology reports. The CRC survival was calculated from the date of diagnosis to the date of cancer-specific death or the end of follow-up (cutoff date: October 2015). Kaplan–Meier method and log-rank test were used for the univariate analysis of survival in various subgroups. The proportional-hazard model Cox was also used in order to consider the effects of different factors on survival including age at diagnosis, place of residence, marital status, occupation, level of education, smoking, economic status, comorbidity, tumor stage, and tumor grade. A total number of 335 patients affected by CRC were assessed and the results showed that 1- and 5-year survival rate were 87% and 33%, respectively. According to the results of Cox's multivariate analysis, the following factors were significantly related to CRC survival: age at diagnosis (≥65 years old) (HR 2.08, 95% CI: 1.17–3.71), single patients (HR 1.62, 95% CI: 1.10–2.40), job (worker) (HR 2.09, 95% CI: 1.22–3.58), educational level: diploma or below (HR 0.61, 95% CI: 0.39–0.92), wealthy economic status (HR 0.51, 95% CI: 0.31–0.82), tumor grade in poorly differentiated (HR 2.25, 95% CI: 1.37–3.69), and undifferentiated/anaplastic grade (HR 2.90, 95% CI: 1.67–4.98). We found that factors such as low education, inappropriate socioeconomic status, and high tumor grade at the time of disease diagnosis were effective in the poor survival of CRC patients in Kurdistan province; this

    In a healthy organization, psychological health and physical health are as important as production and productivity; and healthy workers have higher productivity. Regarding lack of information about workers' general health profile in Qom Province, this study aimed to assess and compare the staffs' general health and its components among different workplaces in 2014. In a cross-sectional study, 2,276 employees working at 46 industries and organizations completed a standardized General Health Questionnaire (GHQ 28) and a demographic questionnaire. Data were analyzed using t-test, ANOVA, and Pearson product-moment correlation coefficient by IBM SPSS version 20. The mean age of the participants was 32.22 (±7.55) years. Seventy-nine point four percent of participants were married and the rest were single. Highest and lowest scores belonged to social dysfunction and depression, respectively. Also, total score of staffs' general health was 17.87 ± 10.93. The results showed that, in spite of the non-relationship between general health score difference among married and single personnel (p > 0.05), there was a significant difference between men and women and among organizations and industries with regards to general health score (p creativity in the workplaces are at risk. Altogether, the general health score in the studied population was suitable in its entirety.

    Full Text Available Background & Aims of the Study: Concentrations of Cd, Hg and As were measured by atomic absorption spectrometry (AAS in muscle, liver and gill tissues of common carp from the Shirinsu Wetland during February to March 2013. Methods: Fish samples (Cyprinus carpio were caught from Shirinsu Wetland, western Iran from February to March 2013. Specimens were frozen in prewashed polyethylene bags and frozen samples brought to the laboratory in ice chests. Samples (2 g were digested with 5 ml of HNO 3 (65% v/v, 1 ml of H 2 O 2 (30% v/v with a microwave oven. A blank digest was carried out in the same way. The digestion program began at a potency of 1200W then ramped for 10 min, after which samples were held for 10 min at 1200W. The second step began at a potency of 0W and held for 15 min. All metal concentrations were determined on a wet weight basis as μg g −1 . Results: Metal levels measured in muscle tissue were in the following ranges (μg g −1 : Cd 0.007-0.011, Hg 0.006-0.01 and As not detected. In liver tissue were (μg g −1 : Cd 0.035-0.043, Hg and As not detected. In gill tissue were (μg g −1 : Cd 0.31-0.55, Hg 0.002-0.004 and As 0.001-0.003. The results presented on metal contents in the examined tissues give an indication of the environmental conditions. Concentrations of Cd, Hg and As obtained were far below the established values by the European Community Regulations. However, Cd level found in gill tissue was higher than the recommended legal limits for human consumption and as such may cause a human health issue. Conclusion: Analytical data shows that the metal concentrations for the fish tissues were generally within the FAO/WHO, ASTDR and EEC recommended limits for fish. Therefore there is no serious health risk associated with the consumption of the three studied metals in the muscle and liver tissues analyzed.

    The determination of brittleness and geomechanical parameters, especially uniaxial compressive strength (UCS) and Young's modulus (ES) of rocks are needed for the design of different rock engineering applications. Evaluation of these parameters are time-consuming processes, tedious, expensive and require well-prepared rock cores. Therefore, compressional wave velocity (Vp) and index parameters such as point load index and porosity are often used to predict the properties of rocks. In this paper, brittleness and other properties, physical and mechanical in type, of 56 Asmari limestones in dry and saturated conditions were analyzed. The rock samples were collected from Khersan 2 dam site. This dam with the height of 240 m is being constructed and located in the Zagros Mountain, in the southwest of Iran. The bedrock and abutments of the dam site consist of Asemari and Gachsaran Formations. In this paper, a practical relation for predicting brittleness and some relations between mechanical and index parameters of the Asmari limestone were established. The presented equation for predicting brittleness based on UCS, Brazilian tensile strength and Vp had high accuracy. Moreover, results showed that the brittleness estimation based on B3 concept (the ratio of multiply compressive strength in tensile strength divided 2) had more accuracy as compared to the B2 (the ratio of compressive strength minus tensile strength to compressive strength plus tensile strength) and B1 (the ratio of compressive strength to tensile strength) concepts.

    Rate of penetration (ROP) is one of the key indicators of drilling operation performance. The estimation of ROP in drilling engineering is very important in terms of more accurate assessment of drilling time which affects operation costs. Hence, estimation of a ROP model using operational and environmental parameters is crucial. For this purpose, firstly physical and mechanical properties of rock were derived from well logs. Correlation between the pair data were determined to find influential parameters on ROP. A new ROP model has been developed in one of the Azadegan oil field wells in southwest of Iran. The model has been simulated using Multiple Nonlinear Regression (MNR) and Artificial Neural Network (ANN). By adding the rock properties, the estimation of the models were precisely improved. The results of simulation using MNR and ANN methods showed correlation coefficients of 0.62 and 0.87, respectively. It was concluded that the performance of ANN model in ROP prediction is fairly better than MNR method.

    A combined geostatitical methodology based on Min/Max Auto-correlation Factor (MAF) analysis and Analytical Hierarchy Process (AHP) is presented to generate a suitable Fault Detection Map (FDM) through seismic attributes. Five seismic attributes derived from a 2D time slice obtained from data related to a gas field located in southwest of Iran are used including instantaneous amplitude, similarity, energy, frequency, and Fault Enhancement Filter (FEF). The MAF analysis is implemented to reduce dimension of input variables, and then AHP method is applied on three obtained de-correlated MAF factors as evidential layer. Three Decision Makers (DMs) are used to construct PCMs for determining weights of selected evidential layer. Finally, weights obtained by AHP were multiplied in normalized valued of each alternative (MAF layers) and the concluded weighted layers were integrated in order to prepare final FDM. Results proved that applying algorithm proposed in this study generate a map more acceptable than the each individual attribute and sharpen the non-surface discontinuities as well as enhancing continuity of detected faults.

    The most fundamental way to decrease the burden of noncommunicable diseases (NCDs) is to identify and control their related risk factors. The goal of this study is to determine socioeconomic inequalities in risk factors for NCDs using concentration index based on Non-Communicable Disease Surveillance Survey (NCDSS) data in Kurdistan province, Islamic Republic of Iran in 2005 and 2009. The required data for this study are taken from two NCDSSs in Kurdistan province in 2005 and 2009. A total of 2,494 persons in 2005 and 997 persons in 2009 were assessed. Concentration index was used to determine socioeconomic inequality. To assess the relationship between the prevalence of each risk factor and socioeconomic status (SES), logistic regression was used and odds ratio (OR) was calculated for each group, compared with the poorest group. The concentration index for hypertension was -0.095 (-0.158, -0.032) in 2005 and -0.080 (-0.156, -0.003) in 2009. The concentration index for insufficient consumption of fruits and vegetables was -0.117 (-0.153, -0.082) in 2005 and -0.100 (-0.153, -0.082) in 2009. The concentration index for the consumption of unhealthy fat and oil was -0.034 (-0.049, -0.019) in 2005 and -0.108 (-0.165, -0.051) in 2009. The concentration index for insufficient consumption of fish was -0.070 (-0.096, -0.044) in 2005. The concentration index for physical inactivity was 0.008 (-0.057, 0.075) in 2005 and 0.139 (0.063, 0.215) in 2009. In all the cases, the OR of the richest group to the poorest group was significant. Hypertension, insufficient consumption of fruits and vegetables, consumption of unhealthy fat and oil, and insufficient consumption of fish are more prevalent among poor groups. There was no significant socioeconomic inequality in the distribution of smoking, excess weight, and hypercholesterolemia. Physical inactivity was more prevalent among the rich groups of society in 2009. The reduction of socioeconomic inequalities must become a main goal in

    Full Text Available  One of the most common causes of emergency department (ED visits in Pasteur Hospital, Bam, Iran, is a foreign body from palm tree fronds entering different parts of body. This town is located in southeast Iran and has many palm tree orchards. Most of its residents are farmers or orchardists and many children play in these orchards. When palm harvest season approaches (about the end of summer, a considerable number of patients are presented to emergency department of this town with complaint of foreign bodies. These foreign bodies called “date thorns” among the locals (figure1 are wooden and can easily penetrate various body parts due to their needle-like, pointy shape. Some patients manipulate the foreign bodies before going to the ED and cause it to move deeper. Another group, delay going to the hospital and only reach ED a few days after the initiation of inflammation, redness, and evidence of infection. History and physical examination aid in finding the place of the foreign body, but sometimes they are not perceptible and diagnostic imaging is needed. Radiolucent objects such as wood cannot be detected in graphy but are visible in sonograms (1, 2. Removal of these bodies is usually performed under sterile conditions, using local anesthesia or regional nerve blockade, by making an incision and searching the region, finding and removing the foreign body, and finally suturing and bandaging. The procedure gets more difficult in children and patients who do not cooperate and occasionally, procedural sedation and analgesia is required, which leads to side effects such as nausea, vomiting, lethargy, agitation, and respiratory depression. Depending on the site of injury, patients are usually unable to use the affected organ for a few days after the procedure and need daily washing and bandage, and sometimes taking antibiotics. If tendon, joint, nerve, or vascular injuries are present, it gets more complicated and need for operation and

    Tetracyclines (TCs), a class of antibiotics with a broad spectrum, are the most frequently used antibiotics in animal production. The major concern is that the widespread use of the antibiotics may lead to the emergence of new strains of bacteria that are resistant to these antibiotics. The objective of this study was to determine the residual levels of oxytetracycline and tetracycline in 80 animal manure samples that were collected from the livestock and poultry feedlots in Khuzestan Province. The residual levels of the antibiotics in the samples were extracted by using solid-phase extraction (SPE) method and subsequently were measured by liquid chromatography. Recoveries from the spiked poultry manure samples ranged from 65 to 113% for tetracycline and 86 to 132% for oxytetracycline. Relative standard deviations of the recoveries were less than 5.7% within the same day. Method detection limit (MDL) measured for oxytetracycline and tetracycline in the manure were 0.011 and 0.01 mg/kg, respectively. Analysis of the collected 50 chickens and 30 cow manure samples showed that the highest concentration of tetracycline was related to Behbahan City (5.36 mg/kg) and the lowest concentration was detected for Ramhormoz (0.05 mg/kg). The highest and lowest concentrations of oxytetracycline were respectively observed for Behbahan (13.77 mg/kg) and Ramhormoz (0.047 mg/kg). Based on the results, in chicken manure, there was significant statistical difference between the residual TC concentrations among five cities (p(value) oxytetracyclin (OTC) residual concentrations among five cities (p(value) > 0.05).

    The aim of this study was to determine the socioeconomic inequalities in nonuse of seatbelts in cars and helmets on motorcycles in Kurdistan Province, west of Iran, 2009. The data used in this study was collected from the data gathered in non-communicable disease surveillance system (NCDSS) in 2009 in Kurdistan. A total of 1000 people were included in this study. The outcome variable of this study was the nonuse of seatbelts and helmets. The socio-economic status (SES) was calculated based on participants' residential area and assets using Principal Component Analysis (PCA) method. The concentration index, concentration curve, and comparison of Odds Ratio (OR) in different SES groups were used to measure the socioeconomic inequalities using logistic regression. In order to determine the contribution of determinants of inequality, decomposition analysis was used. The prevalence of nonuse of seatbelts in cars and helmets on motorcycles were 47.5%, 95%CI [44%, 55%], respectively. The Concentration index was -0.097, CI [-0.148, -0.046]. The OR of nonuse of seatbelts in cars and helmets on motorcycles in the richest group compared with the poorest group was 0.39, 95%CI [0.23, 0.68]. The results of the decomposition analysis showed that 34% of inequalities were due to SES, 47% were due to residential area, and 12% were due to unknown factors. There is a reverse association between SES and nonuse of seatbelts in cars and helmets on motorcycles. This issue must be considered while planning to reduce traffic accidents injuries.

    About 80% of deaths in 350 million cases of diabetes in the world occur in low and middle income countries. The aim of this study was to determine the status of diabetes socioeconomic inequality and the share of determinants of inequalities in Kurdistan Province, West of Iran, using two surveys in 2005 and 2009. Data were collected from non-communicable disease surveillance surveys in Kurdistan in 2005 and 2009. In this study, the socioeconomic status (SES) of the participants was determined based on the residential area and assets using principal component analysis statistical method. We used concentration index and logistic regression to determine inequality. Decomposition analysis was used to determine the share of each determinant of inequality. The prevalence of diabetes expressed by individuals changed from 0.9% (95% CI: 0.6-1.3) in 2005 to 3.1% (95% CI: 2-4) in 2009. Diabetes Concentration Index changed from -0.163 (95% CI: -0.301- -0.024) in 2005 to 0.273 (95% CI: 0.101-0.445) in 2009. The results of decomposition analysis revealed that in 2009, 67% of the inequality was due to low socioeconomic status and 16% to area of residence; i.e., living in rural areas. The prevalence of diabetes significantly increased, and the diabetes inequality shifted from the poor people to groups with better SES. Increased prevalence of diabetes among the high SES individuals may be due to their better responses to diabetes control and awareness programs or due to the type of services they were provided during these years.

    To identify events that could predict province-level frequency of foot-and-mouth disease (FMD) outbreaks in Iran, 5707 outbreaks reported from April 1995 to March 2002 were studied. A zero-inflated negative binomial model was used to estimate the probability of a 'no-outbreak' status and the number of outbreaks in a province, using the number of previous occurrences of FMD for the same or adjacent provinces and season as covariates. For each province, the probability of observing no outbreak was negatively associated with the number of outbreaks in the same province in the previous month (odds ratio [OR]=0.06, 95% confidence interval [CI]: 0.01, 0.30) and in 'the second previous month' (OR=0.10, 95% CI: 0.02, 0.51), the total number of outbreaks in the second previous month in adjacent provinces (OR=0.57, 95% CI: 0.36, 0.91) and the season (winter [OR=0.18, 95% CI: 0.06, 0.55] and spring [OR=0.27, 95% CI: 0.09, 0.81], compared with summer). The expected number of outbreaks in a province was positively associated with number of outbreaks in the same province in previous month (coefficient [coef]=0.74, 95% CI: 0.66, 0.82) and in the second previous month (coef=0.23, 95% CI: 0.16, 0.31), total number of outbreaks in adjacent provinces in the previous month (coef=0.32, 95% CI: 0.22, 0.41) and season (fall [coef=0.20, 95% CI: 0.07, 0.33] and spring [coef=0.18, 95% CI: 0.05, 0.31], compared to summer); however, number of outbreaks was negatively associated with the total number of outbreaks in adjacent provinces in the second previous month (coef=-0.19, 95% CI: -0.28, -0.09). The findings indicate that the probability of an outbreak (and the expected number of outbreaks if any) may be predicted based on previous province information, which could help decision-makers allocate resources more efficiently for province-level disease control measures. Further, the study illustrates use of zero inflated negative binomial model to study diseases occurrence where disease is

    Full Text Available Objective: To model spatial relationship between climatic conditions and annual parasite incidence (API of malaria in southern part of Sistan&Balouchistan Province of Iran using spatial statistic models . Methods: A geographical weighted regression model was applied for predicting API by 3 climatic factors in order to model the spatial API of malaria in Sistan&Baluchistan Province of Iran. Results: The results indicated that most important climatic factor for explaining API in Sistan&Baluchistan was annual rainfall being of more importance in southern part of study area such as Chabahar, and Nikshar. The temperature and relative humidity are of the second and third priority respectively. The importance of these two climatic factors is higher in northern part of the studied region. The spatial autocorrelation (Moran ’s I for standard residual of applied geographical weighted regression model is -0.022 which indicated no spatial patterns. Conclusions: This model explained only 0.51 of API spatial variation (R2=0.51. Thus, the nonclimatic factors such as socioeconomic, lifestyle and the neighborhood position of this province with Afghanistan, and Pakistan also should be considered in epidemiological survey of malaria in Sistan&Baluchistan.

    BACKGROUND: The hemoglobinopathies refer to a diverse group of inherited disorders characterized by a reduced synthesis of one or more globin chains (thalassemias) or the synthesis of structurally abnormal hemoglobin (Hb). The thalassemias often coexist with a variety of structural Hb variants giving rise to complex genotypes and an extremely wide spectrum of clinical and hematological phenotypes. Hematological and biochemical investigations and family studies provide essential clues to the different interactions and are fundamental to DNA diagnostics of the Hb disorders. Although DNA diagnostics have made a major impact on our understanding and detection of the hemoglobinopathies, DNA mutation testing should never be considered a shortcut or the test of first choice in the workup of a hemoglobinopathy. MATERIALS AND METHODS: A careful three-tier approach involving: (1) Full blood count (2) Special hematological tests, followed by (3) DNA mutation analysis, provides the most effective way in which to detect primary gene mutations as well as gene-gene interactions that can influence the overall phenotype. With the exception of a few rare deletions and rearrangements, the molecular lesions causing hemoglobinopathies are all identifiable by PCR-based techniques. Furthermore, each at-risk ethnic group has its own combination of common Hb variants and thalassemia mutations. In Iran, there are many different forms of α and β thalassemia. Increasingly, different Hb variants are being detected and their effects per se or in combination with the thalassemias, provide additional diagnostic challenges. RESULTS: We did step-by-step diagnosis workup in 800 patients with hemoglobinopathies who referred to Research center of Thalassemia and Hemoglobinopathies in Shafa Hospital of Ahwaz Joundishapour University of medical sciences, respectively. We detected 173 patients as iron deficiency anemia (IDA) and 627 individuals as thalassemic patients by use of different indices. We

    The environmental impacts of gold mining and processing on geochemical and biogeochemical cycles in Muteh region located northwest of Esfahan province and northeast of Golpaygan city is investigated. For this purpose systematic sampling was carried out in, rock, soil, water, and sediment environments along with plant, livestocks and human hair samples. Mineralogical and Petrological studies show that ore mineral such as pyrite and arsenopyrite along with fluorine-bearing minerals like tremolite, actinolite, biotite and muscovite occur in green schist, amphibolite and lucogranitic rocks in the area. The hydrochemistry of the analysed water samples indicate that As and F display the highest concentrations among the analysed elements. Indeed arsenic has the highest concentration in both topsoil and subsoil samples when compared with other potentially toxic elements. Anthropogenic activity also have it s greatest effect on increasing arsenic concentration among the analysed samples. The concentration of the majority of the analysed elements in the shoots and leaves of two local plants of the region i.e Artemesia and Penagum is higher than their concentration in the roots. Generally speaking, Artemesia has a greater tendency for bioaccumulating heavy metals. The results of cyanide analysis in soil samples show that cyanide concentration in the soils near the newly built tailing dam is much higher than that in the vicinity of the old tailing dam. The high concentration of fluorine in the drinking water of the Muteh village is the main reason of the observed dental fluorosis symptoms seen in the inhabitants. One of the two drinking water wells which is located near the metamorphic complex and supplies part of the tap water in the village, probably has the greatest impact in this regard. A decreasing trend in fluorine concentration is illustrated with increasing distance from the metamorphic complex. Measurements of As concentration in human hair specimens indicate that As

    Full Text Available Introduction Nitrogen is one of the most abundant elements on earth and major essential for crop growth and development that is heavily used in modern agriculture to maximize yields. Among cereals, maize (Zea mays L. is an important food and feed crop which ranks third after wheat and rice in the world. As N fertilizer costs remain relatively high and environmental concerns over excessive N application increase, the objectives of the present study were: (i to compare maize hybrids growth and yield responses to N rates, (ii to determine optimum N rate for maize grain yield production, (iii to explore the physiological functions controlling maize growth and yield and (iv to identify more effective physiological indices in maize grain production under N stress as well as potential condition. Materials and Methods Two field experiments were conducted in 2014 and 2015 at the Experimental Field of Kerman Agricultural and Natural Resources Research Center, Kerman, Iran. The experiment was laid out as a randomized complete block design with factorial arrangement of treatments and three replications. Four nitrogen rates (0, 92, 220 and 368 kg N ha-1 were applied to three maize hybrids (KSC 704, Maxima and TWC 604. Statistical analysis was done using SAS software (version 9.4. Results and Discussion Due to a significant lack of homogeneity of variance across the two years, data from the two years were treated as independent experiments and analyzed separately. Results showed that both N rates and hybrids had significant effect on growth indices and maize grain yield. The interaction between genotype and N rate was significant for grain yield in 2015 (P < 0.01. Thus, physical slicing was used to do mean comparison. Results showed that KSC 704 and Maxima had quite similar responses to N rates and with an increase in N fertilization, their grain yield also increased. This response, however, was different in case of TWC 604 so that 92 kg N ha-1 showed maximum

    The genetic polymorphisms of 20 autosomal short tandem repeat (STR) loci included in the PowerPlex ® 21 kit were evaluated from 748 unrelated healthy individuals of the Miao ethnic minority living in the Yunnan province in southwestern China. All of the loci reached Hardy-Weinberg equilibrium. These loci were examined to determine allele frequencies and forensic statistical parameters. The genetic relationship between the Miao population and other Chinese populations were also estimated. The combined discrimination power and probability of excluding paternity of the 20 STR loci were 0.999 999 999 999 999 999 999 991 26 and 0.999 999 975, respectively. The results suggested that the 20 STR loci were highly polymorphic, which makes them suitable for forensic personal identification and paternity testing. Copyright © 2017 Elsevier B.V.

    Atmospheric lead (Pb) pollution during the last century in central Yunnan province, one of the largest non-ferrous metal production centers in China, was reconstructed using sediment cores collected from Fuxian and Qingshui Lakes. Lead concentrations and isotopic ratios ((207)Pb/(206)Pb and (208)Pb/(206)Pb) were measured in sediment cores from both lakes. The operationally defined chemical fractions of Pb in sediment core from Fuxian Lake were determined by the optimized BCR procedure. The chronology of the cores was reconstructed using (210)Pb and (137)Cs dating methods. Similar three-phase variations in isotopic ratios and enrichment factors of Pb were observed in the sediment cores from both lakes. Before the 1950s, the sediment data showed low (207)Pb/(206)Pb and (208)Pb/(206)Pb ratios and enrichment factors (EFs=~1), indicating that the sedimentary Pb was predominantly of lithogenic origin. However, these indices were increased gradually between the 1950s and the mid-1980s, implying an atmospheric Pb deposition. The EFs and isotopic ratios of Pb reached their peak during recent years, indicating aggravating atmospheric Pb pollution. The average anthropogenic Pb fluxes since the mid-1980s were estimated to be 0.032 and 0.053 g m(-2) year(-1) recorded in Fuxian and Qingshui cores, respectively. The anthropogenic Pb was primarily concentrated in the reducible fraction. Combining the results of Pb isotopic compositions and chemical speciations in the sediment cores and in potential sources, we deduced that recent aggravating atmospheric Pb pollution in central Yunnan province should primarily be attributed to regional emissions from non-ferrous metal production industries.

    Full Text Available Background: Urinary tract infections (UTIs are one of the most common bacterial diseases. The etiological agents and emergence of antimicrobial resistance UTIs vary according to time and geographical region. Objectives: The present study aimed to determine the prevalence of etiological agents of UTIs and determine their antimicrobial susceptibility pattern to locally available antibiotics. Patients and Methods: This descriptive cross-sectional study was conducted within six months on all patients with clinical symptoms of UTI who referred to Nemazee Teaching hospital, Shiraz, Iran. Clean catch midstream urine samples were collected and cultured on appropriate media in a short time as possible. Conventional bacteriological methods were followed for the isolation and identification of the bacteria. Antimicrobial susceptibility profiles were determined by locally available antibiotics by using disk diffusion method in accordance with CLSI recommendation. Results: In this study, from overall 9991 specimens analyzed 848 (8.5% culture had significant bacterial growth. Of the total positive cultures, 500 (59% cases were female. Escherichia coli (50.6% was the predominant gram-negative isolated pathogen followed by Klebsiella spp. and Enterobacter spp., respectively. Enterococcus isolates (11.2% was the most isolated gram-positive cocci. Nitrofurantoin (80.9%, gentamycin (77.9% and amikacin (65.3% had the most in-vitro antibacterial effect on E. coli isolates as the predominant cause of UTIs. Conclusions: The results of regional assessments, such as our study, provide not only useful information for prescription of more effective empirical therapy, but also good epidemiological background for comparison of our situation with other regions.

    Full Text Available INTRODUCTION: The incidence of end-stage renal disease is increasing worldwide. Earlier studies reported high prevalence rates of obesity and hypertension, two major risk factors of chronic kidney disease (CKD, in Golestan Province, Iran. We aimed to investigate prevalence of moderate to severe CKD and its risk factors in the region. METHODS: Questionnaire data and blood samples were collected from 3591 participants (≥18 years old from the general population. Based on serum creatinine levels, glomerular filtration rate (GFR was estimated. RESULTS: High body mass index (BMI was common: 35.0% of participants were overweight (BMI 25-29.9 and 24.5% were obese (BMI ≥30. Prevalence of CKD stages 3 to 5 (CKD-S3-5, i.e., GFR <60 mL/min/1.73 m(2, was 4.6%. The odds ratio (OR and 95% confidence interval (95% CI for the risk of CKD-S3-5 associated with every year increase in age was 1.13 (1.11-1.15. Men were at lower risk of CKD-S3-5 than women (OR = 0.28; 95% CI 0.18-0.45. Obesity (OR = 1.78; 95% CI 1.04-3.05 and self-reported diabetes (OR = 1.70; 95% CI 1.00-2.86, hypertension (OR = 3.16; 95% CI 2.02-4.95, ischemic heart disease (OR = 2.73; 95% CI 1.55-4.81, and myocardial infarction (OR = 2.69; 95% CI 1.14-6.32 were associated with increased risk of CKD-S3-5 in the models adjusted for age and sex. The association persisted for self-reported hypertension even after adjustments for BMI and history of diabetes (OR = 2.85; 95% CI 1.77-4.59. CONCLUSION: A considerable proportion of inhabitants in Golestan have CKD-S3-5. Screening of individuals with major risk factors of CKD, in order to early detection and treatment of impaired renal function, may be plausible. Further studies on optimal risk prediction of future end-stage renal disease and effectiveness of any screening program are warranted.

    Full Text Available Water is the main constraint for production of agricultural crops. The temporal and spatial variations in water requirement for agriculture products are limiting factors in the study of optimum use of water resources in regional planning and management. However, due to unfavorable distribution and density of meteorological stations, it is not possible to monitor the regional variations precisely. Therefore, there is a need to estimate the evapotranspiration of crops at places where meteorological data are not available and then extend the findings from points of measurements to regional scale. Geostatistical methods are among those methods that can be used for estimation of evapotranspiration at regional scale. The present study attempts to investigate different geostatistical methods for temporal and spatial estimation of water requirements for wheat crop in different periods. The study employs the data provided by 16 synoptic and climatology meteorological stations in Hamadan province in Iran. Evapotranspiration for each month and for the growth period were determined using Penman-Mantis and Torrent-White methods for different water periods based on Standardized Precipitation Index (SPI. Among the available geostatistical methods, three methods: Kriging Method, Cokriging Method, and inverse weighted distance were selected, and analyzed, using GS+ software. Analysis and selection of the suitable geostatistical method were performed based on two measures, namely Mean Absolute Error (MAE and Mean Bias Error (MBE. The findings suggest that, in general, during the drought period, Kriging method is the proper one for estimating water requirements for the six months: January, February, April, May, August, and December. However, weighted moving average is a better estimation method for the months March, June, September, and October. In addition, Kriging is the best method for July. In normal conditions, Kriging is suitable for April, August, December

    The aim of this study was to determine the amount of input–output energy used in peach production and to develop an optimal model of production in Chaharmahal va Bakhtiari province, Iran. Data were collected from 100 producers by administering a questionnaire in face-to-face interviews. Farms were selected based on random sampling method. Results revealed that the total energy of production is 47,951.52 MJ/ha and the highest share of energy consumption belongs to chemical fertilizers (35.37%). Consumption of direct energy was 47.4% while indirect energy was 52.6%. Also, Total energy consumption was divided into two groups; renewable and non-renewable (19.2% and 80.8% respectively). Energy use efficiency, Energy productivity, Specific energy and Net energy were calculated as 0.433, 0.228 (kg/MJ), 4.38 (MJ/kg) and −27,161.722 (MJ/ha), respectively. According to the negative sign for Net energy, if special strategy is used, energy dismiss will decrease and negative effect of some parameters could be omitted. In the present case the amount is indicating decimate of production energy. In addition, energy efficiency was not high enough. Some of the input energies were applied to machinery, chemical fertilizer, water irrigation and electricity which had significant effect on increasing production and MPP (marginal physical productivity) was determined for variables. This parameter was positive for energy groups namely; machinery, diesel fuel, chemical fertilizer, water irrigation and electricity while it was negative for other kind of energy such as chemical pesticides and human labor. Finally, there is a need to pursue a new policy to force producers to undertake energy-efficient practices to establish sustainable production systems without disrupting the natural resources. In addition, extension activities are needed to improve the efficiency of energy consumption and to sustain the natural resources. - Highlights: • Replacing non-renewable energy with renewable

    Methicilin resistance Staphylococcus aureus (MRSA) infections are the major challenges in hospitals, especially in the burn units. The use of molecular typing methods is essential for tracking the spread of S. aureus infection and epidemiological investigations. The aim of this study was to find the profile of the spa types and also the prevalence of each SCCmec type of S. aureus strains in a central burn hospital in southwest of Iran. A total of 81 non-duplicate S. aureus were isolated from burn patients between April 2011 and February 2012. The susceptibility of the isolates against 13 different antibiotics was tested by disk agar diffusion (DAD) method. MRSA strains were identified by amplification of mecA gene. Multiplex-polymerase chain reaction (PCR) technique was used to determine the SCCmec types of MRSA strains and all the S. aureus isolates were typed by spa typing method. Detection of mecA gene showed that 70 (86.4%) of the isolates were MRSA. The highest rate of resistance was observed for penicillin (97.5%) and erythromycin (77.8%). None of the isolates were resistant to vancomycin. Sixty-seven of the 70 MRSA isolates harbored only SCCmec type III and three untypeable isolates. Five different spa types were detected. The most common spa types were t037 (42.5%) and t631 (34.5%) and were only found in MRSA isolates. Only SCCmec type III was found in burn patients which emphasizes the HA-MRSA origin of these strains. Only five different spa types identified in this study are in accordance with one SCCmec type which indicates that a limited number of bacterial colons are circulated in the burn unit in this hospital. © 2015 APMIS.

    Soil infiltration, soil physical and chemical properties, root length density and soil fauna diversity were studied in Phyllostachys heterocycla forests with different mulching times in southwest Zhejiang Province, China. Significant differences of soil infiltration capability were found among the forests with different mulching times and among soil layers. Soil infiltration capability generally declined in the deeper soil layers. With mulching management, soil infiltration capability increased under the first mulching, and then declined with the increase of mulching times. The Kostiakov model was suitable for simulating soil infiltration process. With the extending of mulching times (4 to 6 years), soil pH and total/non-capillary porosity decreased, while soil bulk density, soil orga-nic matter and total nitrogen contents increased significantly. Soil initial, steady, and average infiltration rates as well as the cumulative infiltration amount correlated closely with the length density of roots with diameter from 0.5 mm to 5.0 mm, showing a decreasing tendency with the decrease in root length density. Soil fauna density was highest in the forest under the first mulching, and was lowest after third mulching. The decreased numbers of large and meso-arthropods, including Symphyla, Chilopoda, Diplopoda, Hymenoptera and pseudoscorpions, and the micro-arthropods, including Oribatida, Mesostigmata, Onychiuridae, Neanuridae, Cyphoderidae, and Entomobryidae, showed negative effects on soil infiltration. In conclusion, long-term mulching changed soil physical and chemical properties, decreased soil infiltration capability, and suppressed the development of soil fauna, which might cause the decline ofP. heterocycla forests.

    Picea likiangensis (Franch. ) Pritz. primary forest is one of the dominant forest types in the Small Zhongdian area in Shangri-La County of Yunnan Province. In this paper, the responses of P. likiangensis tree-ring width to climate change were analyzed by dendrochronological methods, and the dendrochronology was built by using relatively conservative detrending negative exponential curves or linear regression. Correlation analysis and response function analysis were applied to explore the relationships between the residual chronology series (RES) and climatic factors at different time scales, and pointer year analysis was used to explain the reasons of producing narrow and wide rings. In the study area, the radial growth of P. likiangensis and the increasing air temperature from 1990 to 2008 had definite 'abruption'. The temperature and precipitation in previous year growth season were the main factors limiting the present year radial growth, and especially, the temperature in previous July played a negative feedback role in the radial growth, while the sufficient precipitation in previous July promoted the radial growth. The differences in the temperature variation and precipitation variation in previous year were the main reasons for the formation of narrow and wide rings. P. likiangensis radial growth was not sensitive to the variation of PDSI.

    In 2010 and 2011, the honey samples of Apis cerana cerana and A. mellifera ligustica were collected from Kunming and Mengzi of Yunnan Province, respectively, aimed to analyze the melissopalynology and tropic niche of the two bee species. The absolute pollen concentration of the honey of A. cerana cerana was 1.55 x 10(4) ind x g(-1), being significantly higher than that (1.01 x 10(4) ind x g(-1)) of A. mellifera ligustica, and the number of nectar plant species collected by A. cerana cerana was 12.9, also significantly higher than that (7.7) collected by A. mellifera ligustica, indicating that A. cerana cerana could utilize more nectar plants, while A. mellifera ligustica had stronger selectivity to the nectar plants. The trophic niche breadth of A. cerana cerana was 0.35, which was significantly higher than that (0.23) of A. mellifera ligustica. The trophic niche overlap index between the two bee species was 0.71, and the interspecific competition index was 0.93, suggesting that the food competition between A. cerana cerana and A. mellifera ligustica was fierce.

    Two porphyry Cu-Mo prospects in northern Sonora, Mexico (Fortuna del Cobre and Los Humos) located within the southwestern North American porphyry province have been dated in order to constrain the timing of crystallization and mineralization of these ore deposits. In Fortuna del Cobre, the pre-mineralization granodiorite porphyry yielded an U-Pb zircon age of 76.5 ± 2.3 Ma, whereas two samples from the ore-bearing quartz feldespathic porphyry were dated at 74.6 ± 1.3 and 75.0 ± 1.4 Ma. Four molybdenite samples from Los Humos porphyry Cu prospect yielded a weighted average Re-Os age of 73.5 ± 0.2 Ma, whereas two samples from the ore-bearing quartz monzonite porphyry gave U-Pb zircon ages of 74.4 ± 1.1 and 74.5 ± 1.3 Ma, showing a Late Cretaceous age for the emplacement of this ore deposit. The results indicate that Laramide porphyry Cu mineralization of Late Cretaceous age is not restricted to northern Arizona as previously thought and provide evidence for the definition of NS trending metallogenic belts that are parallel to the paleo-trench. Porphyry copper mineralization follows the inland migration trend of the magmatic arc as a result of the Farallon slab flattening during the Laramide orogeny.

    The mass mortality of pond-reared scattered mirror carp, Cyprinus carpio, caused by Thelohanellus kitauei, occurred at fish farms in Sichuan Province, southwest China. Morphological and molecular analyses were supplemented with histological evaluation of infected tissues to better understand the route of infection and the pathological effects of T. kitauei on the fish host. The intestine of the diseased host was full of large cysts of the myxosporean. The cysts range from 2 cm to 3.6 cm in diameter. Histopathology indicated that T. kitaue i first invaded the submucosa of the host intestine and then moved into the mucosa layers with the development of their spores, finally entering into the enteric cavity of the hosts after the disruption of mucosa layers. The pyriform spores of T. kitauei were surrounded by the transparent spore sheath, measuring 25.98 μm±0.95 μm in body length, 8.72 μm±0.51 μm in body width, and 7.86 μm±0.26 μm in body thickness. The single polar capsule was pyriform, measuring 14.73 μm±0.92 μm in length and 6.82 μm±0.45 μm in width, with eight to 10 turns of filament coils winding inside. Phylogenetic analysis based on the 18S small-subunit ribosomal DNA sequences indicated that minimal genetic differences were present between T. kitauei samples from South Korea and from China. Close affinity was found between the genus Thelohanellus and Myxobolus. Additionally, two polar capsule nuclei were found at the anterior end of the single polar capsule in spores of T. kitauei stained with hematoxylin and eosin, which suggested the separation of the genus Thelohanellus from Myxobolus.

    Full Text Available Leeches (phylum: Annelida, class: hirudinea could infest wide range of livestock such as cow, buffalo, sheep, goat, horse, mule, ass, dog, pig and even human. In November 2013, a 3-year old jackass from Dehloran county, Ilam province, Iran, was infected through his mouth due to drinking spring water. Symptoms including stress, anxiety and tachycardia were seen. After examining oral cavity of jackass, a leech was observed in upper gum. The leech was measured after separation which was three inches in length. The leech was adult which has dark green with orange lines, and it was identified as Limnatis nilotica species. It seems that using spring, subterranean water, pond etc. is the main causes of livestock infestation with leech. Ranchers could be recommended to decontaminate leech waters to prevent further leech infestation cases.

    It is well known that Organophosphate Compounds are widely used as pesticides. Therefore while handling, applying or using these compounds care and safe use should be considered. The main mechanism of toxicity action of Organophosphate Compounds is the inhibition of Actylcholinestrase and Butrylcholinesrase enzymes. It is well known that the activity measurement of Acetylcholinestrase in whole blood and Butrylcholinestrase in plasma samples are potential biomarker of exposure to Organophosphates compounds.In this study AchE and BchE activities were determined in whole blood and plasma samples of farmers from two different area of Khosestan province of Iran Gotvand and Dashte Azadegan (Iran-Iraq war zone).Determination of enzymes activities were based on the Ellman colorimetric method which was modified byWorek et al. The results obtained in this study showed that Gotvand area showed lower than normal value and Dashte Azadegan (war area) were significantly lower than the mean of activities in reference group (P less than 0.05). Also results of this study showed Acetylcholinestrase and Butrylcholinestrase inhibition can provide a good biomarker of exposure to OP pesticides in field studies in human population with consideration of other different parameters and factors which will be discussed.

    Full Text Available We report the first case of chafer beetle [Anisoplia austriaca (Herbst 1783] mortality caused by Actinomucor elegans var. elegans in wheat fields of the Kurdistan province, Iran. For three years, dead larvae of Anisoplia austriaca were collected from wheat fields of the Kurdistan province. Similar isolates of a fast-growing fungus were recovered from all samples. The fungal isolates were identified as A. elegans var. elegans based on morphological and cultural characteristics. The identity of the species was further confirmed using sequence data of the ITS (Internal Transcribed Spacer region of ribosomal DNA. Koch’s postulates were fulfilled by the inoculation of the larvae of A. austriaca and Galleria mellonella (Linnaeus, 1758 (as the model insect using the spore suspension of A. elegans var. elegans. The viability of sporangiospores was evaluated using a spore dilution technique on germination medium. The results on the pathogenicity (100% mortality in A. austriaca larvae and viability tests (germination: 95.45% demonstrated that A. elegans var. elegans can be considered as a potential biocontrol agent against the chafer beetle. Field experiments are still required to evaluate the capacity of A. elegans as a biological control agent.

    Polychlorinated biphenyl (PCB) contamination of oils from all transformers of the national electrical grid in Tehran, Qom, and Alborz, three central provinces of Iran, was assessed. The concentration of PCBs in transformer oils was determined by gas chromatography. At the national level, the proportions of transformers with oil PCB contents of 5000 ppm were determined to be 85.7, 12.4, 1.6, 0.1, and 0.1%, respectively. About 0.5% of transformer oils (66,000 kg out of 13,342,000 kg) exhibited PCB levels higher than 50 ppm that based on the Stockholm Convention should be phased out before 2025. The contaminated oils contained 91.4% of detected PCBs (132 kg PCBs out of 144 kg PCBs) and were located in 1.9% of transformers (27 transformers out of 1449 transformers). Statistical analysis indicated that the year of manufacture and manufacturing company provided significant effects on PCB contamination (p value transformer oils in Tehran was higher than that of the other provinces that could be mainly caused by the older average year of manufacture. PCB levels higher than 499 ppm were also observed only in Tehran. This study provided valuable information for future studies on identification of PCB-contaminated transformers as well as planning and design of waste management facilities for PCB-contaminated oils at the national level.

    Full Text Available The new millennium is started with rapid growth on knowledge and investment and these two items play essential role to create and increase organizational value. Intellectual capital is often described as intangible assets for moving towards sustainable growth in values. Some studies indicate there is a meaningful correlation between intellectual capital and organizations performance. The goal of this research is to examine of this case in Iran and in one of the biggest and most important province of country, Semnan and in one of its professional banks named Bank of Keshavarzi. In order to collect data, a psychological questionnaire is used based on an already existed version in the literature, which have been successfully implemented in Canada and Malaysia. Cronbach Alpha was used to validate the data by considering importance of statistical sample in this study. A random sampling method was used and 188 professional personnel of Bank in five province were selected to answer the questionnaire. Results show a meaningful relation between components of intellectual capital but this unity and relationship was not confirmed between these components and organizational performance. The highest effect is associated with organizations performance and costumer capital and the lowest effect is associated with human investment.

    Wind energy is a renewable energy resource that has increased in usage in most countries. Site selection for the establishment of large wind turbines, called wind farms, like any other engineering project, requires basic information and careful planning. This study assessed the possibility of establishing wind farms in Ardabil province in northwestern Iran by using a combination of analytic network process (ANP) and decision making trial and evaluation laboratory (DEMATEL) methods in a geographical information system (GIS) environment. DEMATEL was used to determine the criteria relationships. The weights of the criteria were determined using ANP and the overlaying process was done on GIS. Using 13 information layers in three main criteria including environmental, technical and economical, the land suitability map was produced and reclassified into 5 equally scored divisions from least suitable to most suitable areas. The results showed that about 6.68% of the area of Ardabil province is most suitable for establishment of wind turbines. Sensitivity analysis shows that significant portions of these most suitable zones coincide with suitable divisions of the input layers. The efficiency and accuracy of the hybrid model (ANP-DEMATEL) was evaluated and the results were compared to the ANP model. The sensitivity analysis, map classification, and factor weights for the two methods showed satisfactory results for the ANP-DEMATEL model in wind power plant site selection.

    Increasing the use of energy inputs in agricultural section has been led to numerous environmental concerns such as greenhouse gas (GHG) emissions, high consumption of non-renewable resources, loss of biodiversity and environment pollutions. The study was aimed to analyze the energy use efficiency (EUE) and estimation of GHG emissions from rainfed–based canola production systems (RCPSs) in Iran. In this study, data were collected from 35 farms in Golestan province (northeast of Iran) by a face to face questionnaire performed and statistical yearbooks of 2014. The amount of GHG emissions (per hectare) from inputs used in RCPSs was calculated using CO 2 emissions coefficient of agricultural inputs. Results showed that the EUE and net energy (NE) were as 3.44 and 35,537.81 MJ ha −1 , respectively. The value of these indices for the study area indicated that surveyed fields are approximately efficient in the use of energy for canola production. The highest share of energy consumption belonged to nitrogen fertilizer (42.09%) followed by diesel fuel (39.81%). In production of rainfed canola, GHG emission was estimated as 1009.91 kg CO 2 equivalent per hectare. Based on the results, nitrogen fertilizer (44.15%), diesel fuel (30.16%) and machinery (14.49%) for field operations had the highest share of GHG emission. The total consumed energy by inputs could be classified as direct energy (40.09%), and indirect energy (59.91%) or renewable energy (2.02%) and nonrenewable energy (97.98%). These results demonstrate that the share of renewable energies in canola production is very low in the studied region and agriculture in Iran is very much dependent on non-renewable energies. In this study, the energy use status in RCPSs has analyzed and the main involved causes have been interpreted. - Highlights: • Fertilizers had the highest share in GHG emission. • The share of renewable energy was low in canola production. • Canola production is efficient in Iran.

    High consumption of bakery products such as cream-filled pastries may cause serious health risks and food poisoning to humans. Therefore, investigation of the microbial and chemical qualities of bakery products containing cream is necessary. The purpose of the present study was to investigate the chemical qualities and microbial contaminations of cream-filled pastries collected from confectioneries located in six cities in Chaharmahal Va Bakhtiari province (Southwestern Iran). Microbial tests and chemical characteristics (fat and acidity level) were done on 228 cream-filled pastries samples that were collected randomly from various confectioneries. After microbial tests, it was found that 33.33% of all samples were contaminated by microbial agents. The microbial tests showed that Shahrekord (10.09%) and Broujen (9.21%) cities had high levels of contamination and in Koohrang (1.31%) it was low compared with the other four cities. High contamination of coliforms (61.84%), staphylococci (48.68%), and yeast (27.63%) were observed in almost all samples. The chemical analysis showed maximum amounts of fat content and titratable acidity in cream-filled pastry samples obtained from Lordegan and Shahrekord cities, respectively. The findings of the present work demonstrated that the microbial contamination and chemical quality of cream-filled pastries produced in confectionaries of Chaharmahal Va Bakhtiari province were not in acceptable ranges. These problems may be related to fecal contamination of cream samples or lack of hygiene by handlers and it is necessary to observe the standards of hygiene and to develop safe food handling techniques and aseptic pastry manufacturing systems in some confectioneries of Chaharmahal Va Bakhtiari province.

    Efficient use of energy in farming systems is one of the most important implications for decreasing greenhouse gas (GHG) emissions and mitigating global warming (GW). This paper describes the energy use patterns, analyze the economics, and report global warming potential effects of major crop production systems in East Azerbaijan province, Iran. For this purpose, 110 farmers whose main activity was major crop production in the region, including wheat, barley, carrot, tomato, onion, potato, alfalfa, corn silage, canola, and saffron, were surveyed. Some other data was obtained from the Ministry of Agriculture Jihad of Iran. Results showed that, in terms of total energy input, onion (87,556 Mj ha -1 ) and potato (80,869 Mj ha -1 ) production systems were more energy-intensive than other crops. Among the studied crops, the highest values of net return (6563.8 $ ha -1 ) and benefit/cost ratio (1.95) were related to carrot and corn silage production systems, respectively. Studies have also shown that onion and saffron production systems emit the highest (5332.6 kg CO2eq ha -1 ) and lowest (646.24 kg CO 2 eq ha -1 ) CO 2 eq. emission, respectively. When it was averaged across crops, diesel fuel accounted for the greatest GHG contribution with 43% of the total, followed by electric power (28%) and nitrogen fertilizer (21%). In the present study, eco-efficiency was calculated as a ratio of the gross production value and global warming potential effect for the studied crops. Out of all the studied crops, the highest values of eco-efficiency were calculated to be 8.65 $ kg CO 2 eq -1 for the saffron production system followed by the carrot (3.65 $ kg CO 2 eq -1 ) production. Generally, from the aspect of energy balance and use efficiency, the alfalfa production system was the best; however, from an economical point of view, the carrot production system was better than the other crops.

    Full Text Available Background: To reduce traffic injuries in the country, health professionals should have accurate estimates of road traffic deaths. Multiple and sometimes inconsistent statistics presented by organizations in charge create high degree of uncertainty for planners and decision makers. To achieve an accurate estimate, several methods are available. Of them, capture-recapture method seems to be an appropriate and affordable method regarding the reliability of the data sources. This study aimed to estimate the number of road traffic deaths in Kurdistan Province during 2004-2009, using capture-recapture method and based on 2 sources of data obtained from Death Registration System and Forensic Medicine Department. Materials and Methods: All deaths due to road traffic accidents in Kurdistan Province were extracted during 2004-2009. These deaths were legally registered in Death Registration System and Forensic Medicine Department. Shared cases among these 2 sources were identified based on full name, age, gender, and date of death and finally the accurate number of deaths was calculated using the correct volume formula. Results: During study period, Forensic Medicine Department of the province had registered about 3289 cases of road traffic mortalities and Death Registration System had registered 3771 cases of death resulting from road traffic accidents. Using capture-recapture method, the number of deaths in the same years was estimated as 5726 people (5818-5634:CI95%. The proportion of mortality registered in the Death Registration System and Forensic Medicine Department of the province to the total estimated deaths were 65.8% and 57.4%, respectively and both systems together covered 85.4% of road traffic deaths, i.e. under-reporting of about 832 people. Conclusion: The results of the present study indicate that none of 2 sources of Forensic Medicine Department and Death Registration System, per se or both, fully covered road traffic mortalities and

    To determine the prevalence of elevated antibodies and histological changes of celiac disease (CD) on intestinal biopsies among first-degree relatives (FDR) of Iranian children with known CD and to describe the characteristics of the affected FDR. The FDR of 119 patients with CD in Iran were tested for tissue transglutaminase (TTG) and immunoglobulin A (IgA) levels. Upper endoscopy and duodenal biopsy were recommended to those with elevated TTG-IgA antibodies. The characteristics and clinical features of all CD patients were recorded. Altogether 480 FDR (52.7% females) participated in the study, of whom 63 had an elevated TTG-IgA and 44 consented to undergo endoscopy with biopsies. Histology revealed Marsh 0 in six, Marsh I in seven, Marsh II in four and Marsh III in 27. Most of those with Marsh II or III changes were siblings (26/31). The prevalence of TTG-IgA positivity among FDR was 13.1% and for biopsy-confirmed CD (Marsh II and III) it was 6.5%. Most FDR with CD had symptoms, with the most common being abdominal pain (45.0%), followed by musculoskeletal pain (35.5%) and constipation (25.8%). FDR with Marsh III changes had significantly higher levels of TTG-IgA. The prevalence of CD in FDR in Iran is much higher compared with the general population (6.5% vs 0.5-0.6%). Testing should be considered for all FDR of Iranian patients with known CD and in particular in symptomatic cases. © 2016 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    This research aims to determine the mental health status of population aged 15 and over in the province of Tehran in 2015. This cross-sectional survey was performed on 1,200 individuals aged fifteen years and older, living in urban, and rural areas of the three main districts of Tehran, Shahriar, and Nasimshahr of Tehran Province. Individuals were enrolled in the study by clustered and systematic randomization. The General Health Questionnaire-28 (GHQ-28) was used for screening for common mental disorders. Those scoring above the cut-off point of the GHQ-28 were considered to be suffering from at least one mental disorder. All data was analyzed using the SPSS-18 software. According to our data, 30.2% of the subjects (34.2% of females and 26.4% of males) were suspected of having mental disorders. The prevalence of suspected psychiatric disorders in urban areas (35.1%) was higher than the prevalence of these disorders in rural areas (18.2%). Scoring above the cut-off point of the GHQ-28 also had a positive correlation with age, especially among those aged 65 years old and above. Somatization and also symptoms of anxiety were more prevalent than social dysfunction and depressive symptoms, and also more prevalent among females compared to males. Being suspected of a mental disorder was also more prevalent among those who had been divorced, widowed, unemployed, and having post-graduate university education. The results of this study show that about one third of our sample population were suspected of suffering from a mental disorder. The prevalence of common mental disorders has increased from 21.2% in 1999 to 31.7% in 2015. Therefore, it is strongly recommended that public health authorities put more effort to ensure necessary requirements encompassing prevention and promotion of mental health of the Iranian population residing in Tehran province.

    In this paper, atmospheric origins of the widest wildfire in Mazandaran province on 11-13th of December, 2010 have been investigated. Data sets of this research include maximum daily temperature (MDT), minimum relative humidity (MRH) of terrestrial stations, dynamic and thermodynamic features of the atmosphere, Gridded data sets of Self-Calibrated Palmer drought severity index (SCPDSI) and global drought dataset standardized precipitation-evapotranspiration index (SPEI) and data related to the time and the extent of the wildfire. The ``environmental to circulation'' approach to synoptic classification has been used to investigate relationships between local-scale surface environment (wildfire) and the synoptic-scale atmospheric circulation conditions. Results of study show that during the 3-day wide wildfire, the average of MDT and the MRH was significantly different from the long-term average. During the aforementioned wildfire, the average of MDT in Mazandaran province was 26 °C and the average of MRH was reported 35 %. The long-term average of MDT and the MRH in Mazandaran province during 3 days of wildfire was 12.3 °C and 68 %, respectively. Therefore, the MDT has a positive abnormality of 13.7 °C and the MRH has a negative abnormality of 33 %. In addition, monthly SCPDSI and SPEI indicated severe drought conditions at December 2010 in Mazandaran. Analysis of SLP maps shows that during the 3-day fire, a pressure center of 1110 hPa on Persian Gulf and a very low-pressure center on Turkey and Asia Minor were created. Normally, this event has caused the pressure gradient and warm and dry air advection from Arabian Peninsula to higher longitudes, particularly Mazandaran province. Consequently, the MDT increased and the wildfire of Mazandaran forest took place in an area of 220 ha. Zonal wind maps signify the weakness of Zonal wind and meridional wind maps show the southern direction of meridional wind flow during the wide wildfire. Moreover, Omega maps prove

    The aim of this study was to determine the amount of input-output energy used in potato production and to make an economic analysis of potato production in Hamadan province, Iran. Data for the production of potatoes were collected from 100 producers by using a face to face questionnaire method. The population investigated was divided into two groups. Group I was consisted of 68 farmers (owner of machinery and high level of farming technology) and Group II of 32 farmers (non-owner of machinery and low level of farming technology). The results revealed that 153071.40 MJ ha{sup -1} energy consumed by Group I and 157151.12 MJ ha{sup -1} energy consumed by Group II. The energy ratio, energy productivity, specific energy, net energy gain and energy intensiveness were calculated. The net energy of potato production in Group I and Group II was 4110.95 MJ ha{sup -1} and -21744.67 MJ ha{sup -1}, respectively. Cost analysis showed that total cost of potato production in Groups I and II were 4784.68 and 4172.64 $ ha{sup -1}, respectively. The corresponding, benefit to cost ratio from potato production in the surveyed groups were 1.09 and 0.96, respectively. It was concluded that extension activities are needed to improve the efficiency of energy consumption in potato production. (author)

    Predicting the mass of solid waste generation plays an important role in integrated solid waste management plans. In this study, the performance of two predictive models, Artificial Neural Network (ANN) and Multiple Linear Regression (MLR) was verified to predict mean Seasonal Municipal Solid Waste Generation (SMSWG) rate. The accuracy of the proposed models is illustrated through a case study of 20 cities located in Fars Province, Iran. Four performance measures, MAE, MAPE, RMSE and R were used to evaluate the performance of these models. The MLR, as a conventional model, showed poor prediction performance. On the other hand, the results indicated that the ANN model, as a non-linear model, has a higher predictive accuracy when it comes to prediction of the mean SMSWG rate. As a result, in order to develop a more cost-effective strategy for waste management in the future, the ANN model could be used to predict the mean SMSWG rate. Copyright © 2015 Elsevier Ltd.

    Head trauma is the main cause of disabilities and death among young people, and the side effects of head trauma pose some of the greatest medical challenges. Rapid diagnosis and the use of proper treatments can prevent more severe brain damage. The purpose of this research was to determine the quality of nursing services provided to brain trauma patients in hospitals in Guilan Province, Iran. The study was conducted as a descriptive, cross-sectional study in the emergency wards of selected hospitals in Guilan in 2012. The research population was comprised of all the brain trauma patients in these hospitals. We developed a two-section questionnaire, ascertained its validity, and determined that it had a reliability of 88% (Cronbach's alpha). Subsequently, we used the questionnaire for gathering data. The data were analyzed using SPSS statistical software, and descriptive analysis tests (frequency rate and average) and deductive analyses tests (chi-squared) also were used. The results showed that the quality of health services provided to brain-trauma patients in the emergency ward was at the moderate level of 58.8% of the cases and at a low level in 41.2% of the cases. Based on the results that showed that the services were of moderate quality, the staff members in the emergency ward were required to update their knowledge and use the required measures to minimize or prevent side effects in brain-trauma patients; clearly, mastery of such measures was a real need among the emergency ward's staff.

    In present study 30 groundwater samples were collected from Sarpol-e Zahab area, Kermanshah province of Iran in order to assess the quality of groundwater in subjected area and determining its suitability for drinking and agricultural purposes. Also the variations in the quality levels of groundwater were compared over the years of 2015 and 2016. Statistical analyses including Spearman correlation coefficients and factor analysis display good correlation between physicochemical parameters (EC, TDS and TH) and Na + , Mg 2+ , Ca 2+ , Cl - and [Formula: see text] ionic constituents. Also in order to assess water quality for irrigation we used the United States Department of Agriculture (USDA) classification which is based on SAR for irrigation suitability assessment. In addition, the residual sodium carbonate (RSC), %Na, PI, KR, SSP, MH, EC characteristics were calculated for all samples and used for assessment of irrigation suitability. Based on these indicators, for every two years, the quality of water for agriculture is in good and excellent category. The Piper classification for hydro geochemical facies indicates that the water in the study area is of Ca-HCO 3 - type. However, the study of water hardness shows that more than 80% of samples are in hard and very hard water class. Therefore, there is a need for decisions to refine and soften the water.

    Full Text Available The objective of this study was to study the seed quality aspects of wheat (Triticum aestivum L. and the extent of weed seed contamination present in wheat seeds produced in different regions of Iran. Four districts (cities, each including 12 fields (six certified seed fields and six farm-saved seed fields, were selected in each regions (provinces. One kilogram of the wheat seed sample was collected from each field for analysis in the laboratory. Wheat seeding was commonly done by farm-saved seed sourced from within the farm due to the high costs of certified seeds purchased from outside sources, followed by the low seed quality. The use of a farm-saved seed resulted in a higher germination rate and a lower mean time to germination compared with another system. The more positive temperatures experienced by mother plants could decrease the number of normal seedling and seedling length vigor index. Generally there was virtually no difference about physiological quality between certified seed and farm-saved seed sector that is related to lower quality of certified seed. The certified produced seeds had the lower number of weed seed, species and genus before and after cleaning. The highest seed purity and 1000 seed weight was obtained from the certified seed production system. The need for cleaning the farm-saved seed samples before sowing is one of the important findings of this survey.

    Full Text Available The objective of this survey was to evaluate the energy consumption and the economic analysis of cotton production in Esfahan province of Iran. For this purpose, data were selected from 47 cotton growers using a face-to-face questionnaire. The results indicate that cotton production consumed a total energy of 52507.8 MJ ha-1. Among sources of input energy, the contribution of energy related to diesel fuel (47% was highest, followed by chemical fertilizers (20% and water for irrigation (12%. The shares of direct and non renewable energy were 68.3% and 77.7%, respectively. The impacts of indirect and non-renewable energy on cotton yield were higher than those of direct and renewable energy. Energy use efficiency, specific energy, energy productivity, energy intensiveness, and net energy were 0.7, 19.2 MJ-1 kg, 0.10 kg MJ-1, 27.2 MJ-1 $ -1, -15625.2 MJ-1ha-1, respectively. Total cost of cotton production was 1927.9 $ ha-1. About 67% of the cost of production was variable costs, while 33% was fixed costs. The benefit to cost ratio was estimated 1.22. It is suggested that efforts to increase energy efficiency of cotton production in the investigated area should primarily focus on proper use of fertilizers and irrigation systems and also on saving diesel fuel by improving machinery operating performance.

    Full Text Available As more people live in cities and urban areas, evaluation of urban environmental quality is nowadays an unavoidable necessity. Urbanization gives off heavy metals into urban soils and threatens the human health. In this study, urban soil samples were acquired from different locations (Public parks, streets, and squares from Borujerd, Iran. The levels of Cd and Pb in the soils, along with soil pH, electrical conductivity (EC, and particle size distribution (texture, were analyzed. Kriging method by Surfer software was employed to create the spatial distribution maps of Cd, Pb, and geoaccumulation index (Igeo. The average Cd and Pb concentrations in the surface soil samples were 2.50±1.14, and 50.37±34.77 mg/kg dry weight, respectively. The highest mean concentration of Cd was found in street soils and as for Pb in square soils. The interpolation maps illustrated the same behavior for Cd and Pb with elevated concentrations located in the southeast. The mean values of geoaccumulation index (Igeo showed that soils are moderately/strongly contaminated with Cd and moderately contaminated with Pb. In this study, traffic emission, textile industries and probably released untreated municipal wastewater into the soil are anthropogenic sources of Pb and Cd.

    Improving quality of maternal care as well as patients' safety are two important issues in health-care service. Therefore, this study aimed to assess the culture of patient safety at maternity units. This cross-sectional study was conducted among staffs working at maternity units in seven hospitals of Ilam city, Iran. The staffs included in this study were gynecologists and midwifes working in different positions including matron, supervisors, head of departments and staffs. Data were collected using the Hospital Survey on Patient Safety Culture (HSOPSC). This study indicated that 59.1% of participants reported fair level of overall perceptions of safety and 67.1% declared that no event was reported during the past 12 months. The most positively perceived dimension of safety culture was teamwork within departments in view of managers (79.41) and personnel (81.10). However, the least positively perceived dimensions of safety culture was staffing levels. The current study revealed areas of strength (teamwork within departments) and weakness (staffing, punitive responses to error) among managers and personnel. In addition, we found that staffs in Ilam's hospitals accept the patient safety culture in maternity units, but, still are far away from excellent culture of patient safety. Therefore, it is necessary to promote culture of patient's safety among professions working in the maternity units of Ilam's hospitals.

    Androgenic-anabolic steroids (AAS) are abused by a growing number of bodybuilders. This descriptive cross-sectional study was conducted to determine prevalence and patterns of AAS use by bodybuilders in Hamadan, western Iran. In this cross-sectional study, participants were recruited from five gym clubs in two area of Hamadan (a total of 10 clubs). Twenty-five bodybuilders from each club were administered. Questions investigating demographic information, sport history, education level, general knowledge about AAS, and their side effects were asked. Statistical analysis was performed using SPSS 16. The frequency of AAS use was 28.8% (72/250). Fifty-four percent of users were 25 years or younger. AAS abuse showed a significant association with duration of exercise. The drugs were suggested mostly from peers (43.1%) and coaches (36.1%). The most commonly consumed anabolic steroid was testosterone (66.7%). The most commonly reported AAS side effect was acne (18.1%). There was not significant association between general knowledge about side effects of ASS and their use. The results of current survey indicate that frequency of ASS use is high in adolescents and young adult bodybuilders. Well educated bodybuilders have a higher prevalence of abuse. Awareness about the side effects of drugs is not deterrent factor for their abuse. Iranian Ministry of Sport and the Youth, and the National Council for Youth, should be urged to conduct more effective prevention strategies.

    Full Text Available Current conventional agricultural systems using intensive energy have to be revitalized through new integrated approaches relying on renewable energy resources, which can allow farmers to stop dependence on fossil resources. The aim of this study was determining the amount of input–output energy used in onion (Allium cepa L. production in Khorasan Razavi province. For this purpose, the data was collected from 55 onion farm workers in Khorasan Razavi. Inquiries were conducted in face-to-face interviews in April-May 2011. Farm workers were selected based on random sampling method. The results indicated that total energy input was 98479 MJ.ha-1. The share of electricity and nitrogen fertilizer was 50.9 and 14.7%, respectively out of total energy input. The average onion yield under normal conditions was 73227 kg.ha-1 on irrigated farms. The net energy and energy productivity values were estimated to be 18684 MJ.ha-1 and 0.74 kg.MJ-1, respectively, and the ratio of energy output to energy input was found to be 1.19. This indicated an intensive use of input in onion production, which is not parallel to the increase in the final yield. Approximately 77.3% of the total energy input used in onion production was non-renewable (machinery, diesel, fertilizers, chemicals and electricity and only 22.7% was renewable energy form (human labor, manure, water for irrigation, seeds. Cost analysis revealed that total cost of onion production for one hectare was 79262908 Rials. Benefit–cost ratio was calculated as 1.65. Although energy efficiency of onion production in Khorasan Razavi province is low, it is economically justified.

    Full Text Available Background & Aims of the Study: Promoting the health and safety is an important part of the fundamental mission of schools and one factor in designing and operating schools that always has been important is lighting. As students spend considerable hours in the classroom and school, lighting should be designed appropriately and in accordance with the standards, to protect them from injuries. Therefore, this study aimed to determine the combination of natural and artificial lighting condition in primary schools of Baneh city, Kurdistan, Iran. Materials & Methods: This is a cross-sectional study. It's population consisted of primary schools in the city of Baneh and 12 schools were randomly selected as samples. Measurement has been done, using observation method in those schools by completing the assessment form. Then collected data were analyzed by SPSS 19, using descriptive statistics, one-way ANOVA and Kruskal Wallis Test. Results: Results showed that the windows to the floor area in the most of schools classes were in standard range and just in 7 classes, the windows to the floor area ratio were less than standard. ANOVA showed the mean of luminance in those schools in p≤0.05 was significant and most of classes were in range of standard luminance. Comparison of luminance in schools corridors with standard showed that corridors luminance of 3schools were less than standard range. Conclusions: The amount of luminance in all schools was not appropriate especially in old schools. Therefore, to reduce the effect of inappropriate lightning on health in some classes, it is necessary to redesign the system. Furthermore, for parsimony, the lightning system modification is required to achieve standard luminance which is important.

    2017-08-01

    Full Text Available Introduction: Corn (Zea mays L. is cultivated widely throughout the world and has the highest production among the cerealsafter rice and wheat. In Iran the total production of corn in 2013 was more than 2540000 tons. Weeds are one of the greatest limiting factors to decrease corn yield in Iran as the average yield loss due to weeds in the fields of Kermanshah in 2009 was 17.32 %. The herbicides are the main weed control method in conventional cropping systems but their application has been increased herbicide resistant weeds and environmental pollution. Integrated weed management combines all applicable including chemical and non-chemical methods to reduce the effect of weeds in the cropping systems. Thus, Weed control strategies such as tillage, mulch, cover crops and intercropping could be used for integrated weed management of corn. Previous studies showed that crop residues such as rye (Secale sereal L., wheat (Triticum aestivum L., barley (Hordeum vulgare L. and clover (Trifolium sp., cover crops and living mulch could inhibit weed germination and growth. Therefore the objective of this study was evaluating the effects of some integrated weed management treatments on weed characteristics, yield components and grain yield of corn. Materials and methods: In order to evaluate the effect of some weed management treatments on corn (Zea mays L. yield an experiment was conducted in 2014 in Ravansar, Kermanshah, Iran. This study was arranged based on randomized complete block design with 10 treatments and three replications. The weed management treatments were including 1-chemical control followed by mechanical control (application of nicosulfuron at a dose of 80 g.a.i.ha-1 + cultivator 40 days after emergence 2- chemical control followed by mechanical control (application of 2,4-D+MCPA at a dose of 675 g.a.i.ha-1 + cultivator 40 days after emergence 3- cultural control followed by mechanical control (planting hairy vetch (Vicia villosa in the fall

    Colorectal cancer (CRC) survival varies at individual and geographically level. This population-based study aimed to evaluating various factors affecting the survival rate of CRC patients in Kurdistan province.In a retrospective cohort study, patients diagnosed as CRC were collected through a population-based study from March 1, 2009 to 2014. The data were collected from Kurdistan's Cancer Registry database. Additional information and missing data were collected reference to patients' homes, medical records, and pathology reports. The CRC survival was calculated from the date of diagnosis to the date of cancer-specific death or the end of follow-up (cutoff date: October 2015). Kaplan-Meier method and log-rank test were used for the univariate analysis of survival in various subgroups. The proportional-hazard model Cox was also used in order to consider the effects of different factors on survival including age at diagnosis, place of residence, marital status, occupation, level of education, smoking, economic status, comorbidity, tumor stage, and tumor grade.A total number of 335 patients affected by CRC were assessed and the results showed that 1- and 5-year survival rate were 87% and 33%, respectively. According to the results of Cox's multivariate analysis, the following factors were significantly related to CRC survival: age at diagnosis (≥65 years old) (HR 2.08, 95% CI: 1.17-3.71), single patients (HR 1.62, 95% CI: 1.10-2.40), job (worker) (HR 2.09, 95% CI: 1.22-3.58), educational level: diploma or below (HR 0.61, 95% CI: 0.39-0.92), wealthy economic status (HR 0.51, 95% CI: 0.31-0.82), tumor grade in poorly differentiated (HR 2.25, 95% CI: 1.37-3.69), and undifferentiated/anaplastic grade (HR 2.90, 95% CI: 1.67-4.98).We found that factors such as low education, inappropriate socioeconomic status, and high tumor grade at the time of disease diagnosis were effective in the poor survival of CRC patients in Kurdistan province; this, which need more attention.

    To predict the trend of cutaneous leishmaniasis and assess the relationship between the disease trend and weather variables in south of Fars province using Seasonal Autoregressive Integrated Moving Average (SARIMA) model. The trend of cutaneous leishmaniasis was predicted using Mini tab software and SARIMA model. Besides, information about the disease and weather conditions was collected monthly based on time series design during January 2010 to March 2016. Moreover, various SARIMA models were assessed and the best one was selected. Then, the model's fitness was evaluated based on normality of the residuals' distribution, correspondence between the fitted and real amounts, and calculation of Akaike Information Criteria (AIC) and Bayesian Information Criteria (BIC). The study results indicated that SARIMA model (4,1,4)(0,1,0) (12) in general and SARIMA model (4,1,4)(0,1,1) (12) in below and above 15 years age groups could appropriately predict the disease trend in the study area. Moreover, temperature with a three-month delay (lag3) increased the disease trend, rainfall with a four-month delay (lag4) decreased the disease trend, and rainfall with a nine-month delay (lag9) increased the disease trend. Based on the results, leishmaniasis follows a descending trend in the study area in case drought condition continues, SARIMA models can suitably measure the disease trend, and the disease follows a seasonal trend.

    Full Text Available Background and Objectives: In recent years, systemic fungal infections caused by Candida species are one of the important causes of mortality due to increased immunosuppressive diseases. The prevalence of these fungal infections hasled to greater use of antifungal drugs and significant increase in intrinsic or acquired resistance of Candida species to antifungal agents. This research was conducted with the aim of investigating the prevalence and frequency of candidiasis in vaginal samples of women referred to health centers in Qom province and evaluating the target drug resistance pattern. Methods: This study was a descriptive cross-sectional study performed on 150 suspected candidiasis patients. The specimens were examined by direct method and were cultured on Sabouraud’s dextrose agar (containing chloramphenicol, corn meal agar (containing Tween 80, and CHROM agar candida; germ tube test and sugar assimilation test (API20C kit were performed to isolate and differentiate the Candida species. Then, the effect of different antifungal drugs was tested using disk diffusion method. Results: Out of 150 specimens, 83 cases (55.3% of Candida species were identified. Statistical analysis of isolated samples showed that Candida albicans (62.6%, Candida krusei (33.7%, and Candida tropical (3.6% had the highest frequency. Resistance pattern of these species were different to various antifungal drugs. Conclusion: The results of this study showed that Candida albicans is the most frequent among species isolated from patients, and all the isolated Candida species are 100% susceptible to fluconazole and amphotericin B.

    Full Text Available Despite extensive research on stress among hospital nurses, the important effects of support and stress on care quality are not yet well established. Similar to other jobs, nurses face stress in their routine working day. The relationship between occupational stress, social support and factors relating to each of them, among Iranian nurses are attempted to correlate. This cross-sectional analytical-descriptive study was carried out in 2013 in Zanjan province where 248 nurses filled the given questionnaires including Demographic data, Work Factors, Nursing Stress Scale, and Social Integration Scale. Data were analyzed using SPSS 16.00. In our study, we found that the stress and social support were significantly correlated. Our findings revealed a significant relation between social supports and occupational stress in nurses. Conclusively, support from supervisors and coworkers can help control nurses’ stress. In addition, both social support and occupational stress are related to three major components: job satisfaction, job security and others' attitude towards nursing. Therefore, creating a positive attitude towards nursing in society, and a suitable working environment for them is a way to increase their efficiency.

    Full Text Available Background: Treatment of Cutaneous Leishmaniasis (CL is being faced with serious difficulties in Fars Province, due to emerging of resistance against meglumine antimonite (Glucantime®. In this context, determining some biomarkers for drug sensitivity monitoring seems to be highly essential. Different studies have been carried out to decipher the genes might be involved in antimony resistant phenotype in Leishmania spp. Here, we selected three genes: AQP (as drug transporter, TDR-1-1(as drug activator, and γ-GCS (inducing reduction environment for comparative expression analysis on clinical resistant and sensitive isolates of L. major.Methods: The clinical isolates of L. major were collected from CL patients referred to Valfajr Health Center, Shiraz from Oct 2011 to Feb 2012. The susceptibility test was performed to confirm drug sensitivity of strains in vitro as well. Then, the gene expression analysis was performed by quantitative real-time PCR using SYBR® Green.Results: By comparison of expression level between strains, up regulation of γ-GCS gene and down regulation of AQP gene were observed in resistant strains compared to the sensitive isolates; however, down regulation of AQP was not statistically specific. Analysis of TDR-1-1 gene unexpectedly showed a high level of expression in the non-responsive cases.Conclusion: The γ-GCS, at least, can be considered as a suitable molecular marker for screening antimony sensitivity in clinical isolates, although AQP and TDR-1-1gene seem not to be reliable resistant markers.

    Full Text Available Background: Salmonella spp. are widespread zoonotic pathogens with economic importance for both humans and animals. They are categorized as the natural flora of the gastrointestinal tract of many reptiles. Human salmonellosis acquired from contact with reptiles is a well-recognized medical problem. Objective: The frequency of Salmonella contamination in Caspian pond turtles was surveyed to evaluate the danger of exposure or disease risk for humans as these species are abundant around the villages in Golestan and Mazandaran provinces. Materials and Methods: One hundred fifty fecal samples from Caspian pond turtles were tested by standard bacteriological methods and positive samples were serotyped. Antimicrobial susceptibility tests on isolated Salmonella strains were also performed. Results: Out of 150 samples, 54 turtles were detected to be contaminated with Salmonella. Of the 54 Salmonella isolates, 38.8% (21/54 were serotyped as S. typhimurium; 35.1% (19/54 as S. enterica subsp. enterica; 9.2% (5/54 as S. enterica subsp. salamae; 9.2% (5/54 as S. enterica subsp. arizona; and 7.4% (4/54 as S. enterica subsp. houtenae. Female (28/80, 35% and male (26/74, 35.1% turtles showed equal incidence of Salmonella spp. contamination. Resistance was mostly observed against ampicillin (37% followed by tetracycline (33.3%, nalidixic acid (7.4%, ciprofloxacin (5.5%, and cotrimoxazole (3.7%. The highest susceptibility was observed against gentamicin (100% and trimethoprim (98.1%. Conclusion: Our findings confirmed that people who are in close exposure to Caspian pond turtles and their feces are at the risk of Salmonella contamination. Accordingly, fundamental principles of hygiene should be applied in human contact with Caspian pond turtles. Furthermore, people should be educated about the Salmonella contamination which may occur through Caspian pond turtles.

    The chemical analysis of 129 groundwater samples in the Kadkan area, Khorasan-e-Razavi Province, NE of Iran was evaluated to determine the hydrochemical processes, assessment of groundwater quality for irrigation purposes, corrosiveness, and scaling potential of the groundwater. Accordingly, the suitability of groundwater for irrigation was evaluated based on the sodium adsorption ratio, residual sodium carbonate, sodium percent, salinity hazard, and US Salinity Laboratory hazard diagram. Based on the electrical conductivity and sodium adsorption ratio, the dominant classes are C3-S1, C3-S2, C2-S1, and C4-S2. According to the Wilcox plot, about 50 % of the samples fall in the "Excellent to Good" and "Good to Permissible" classes. Besides, the Langelier saturation index, Ryznar stability index (RSI), Larson-Skold index, and Puckorius scaling index were evaluated for assessing the corrosiveness and scaling potential of the groundwater. Corrosiveness and scaling indices stated that the majority of samples are classified into "Aggressive" and "Very Aggressive" category. In addition, chloride and sulfate interfere in 90 % of the samples. Assessment of hydrochemical characteristics indicates Na-Mg-Cl as the predominant hydrochemical type. Spatial distribution of hydrochemical parameters indicates that hydrochemical processes are influenced by geology and hydrogeology of Kadkan aquifer. The Gibbs plots gave an indication that groundwater chemistry in this area may have acquired the chemistry mainly from evaporation and mineral precipitation. Grouping the samples based on Q-mode hierarchical cluster analysis helped to more separation of similar samples. The R-mode HCA grouped analyzed parameters into two groups based on similarity of hydrochemical characteristics. As a result, the samples collected in northern and southern parts of the study area show the best quality (i.e., lowest salinity) for some purposes such as irrigation and drinking.

    This research aims to determine the mental health status of population aged 15 and over in the province of Kohghilouyeh and Bouyerahmad in 2015. The statistical population of this cross-sectional field survey consisted of residents of urban and rural areas of Kohghilouyeh and Bouyerahmad in Iran. An estimated sample size of 1200 people was chosen using systematic random cluster sampling. The access was provided by the contribution of Geographical Post Office of Yasuj, Dogonbadan, and Dehdasht cities. The General Health Questionnaire-28 (GHQ-28) was used as a screening tool for mental disorders. Data analysis in the current study was carried out using the SPSS-18 software. Using GHQ traditional scoring method, the results showed that 16.9% of the subjects showed to be at risk of mental disorders (20.1% of females and 13.4% of males). Urban areas (18.3%) were more at risk of mental disorders compared with rural residents (13.9%). Anxiety and somatization symptoms were more frequent than depression and social dysfunction among respondents. The obtained data revealed that the prevalence of mental disorders increased with age. The results also indicated that mental disorders were more common in certain subgroups; in particular women, those aged 65 years and above, the divorced and widowed, illiterate and retired adults. Our findings suggest that one sixth of the participants are at risk of developing mental disorders. Although the prevalence of these disorders has decreased from 26.2% to 16.9% between 1999 and 2015, it is still of great importance to further promote mental health policies and advocate psychological welfare of those suffering from mental disorders along with their re-empowerment.

    Since 1989, an increasing number of sinkhole occurrences have been reported in the Kabudar Ahang and Razan-Qahavand subcatchments (KRQ) of Hamadan province, western Iran. The sinkhole-related subsidence phenomenon poses a significant threat for people and human structures, including sensitive facilities like the Hamadan Power Plant. Groundwater over-exploitation from the thick alluvial cover and the underlying cavernous limestone has been identified as the main factor involved in sinkhole development. A sinkhole susceptibility model was produced in a GIS environment applying the analytical hierarchy process (AHP) approach and considering a selection of eight factors, each categorized into five classes: distance to faults (DF), water level decline (WLD), groundwater exploitation (GE), penetration of deep wells into karst bedrock (PKA), distance to deep wells (DDW), groundwater alkalinity (GA), bedrock lithology (BL), and alluvium thickness (AT). Relative weights were preliminarily assigned to each factor and to their different classes through systematic pairwise comparisons based on expert judgment. The resulting sinkhole susceptibility index (SSI) values were then classified into four susceptibility classes: low, moderate, high and very high susceptibility. Subsequently, the model was refined through a trial and error process involving changes in the relative weights and iterative evaluation of the prediction capability. Independent evaluation of the final model indicates that 55% and 45% of the subsidence events fall within the very high and high, susceptibility zones, respectively. The results of this study show that AHP can be a useful approach for susceptibility assessment if data on the main controlling factors have sufficient accuracy and spatial coverage. The limitations of the model are partly related to the difficulty of gathering data on some important geological factors, due to their hidden nature.

    Full Text Available Giardia lamblia is one of the most prevalent intestinal flagellate protozoa that infects a wide range of vertebrate hosts causing severe intestinal disorder in children.This study was performed to determine subspecies of G.lamblia by the PCR-RFLP method, targeting the glutamate dehydrogenase(gdhlocus, in hospitalized children at Urmia Mutahhari Hospital, West Azerbaijan Province,Iran and determining the infection transformational storages in this area.Overall, 720 stool specimens were collected from the hospitalized children, 34 samples were positive and Giardia cysts were detected under the microscope. Cysts were partially purified by the sucrose density gradient method and then washed with sterile distilled water to remove effectively the PCR inhibitors. Genomic DNA of G. lamblia isolates was extracted by freeze-thaw cycles followed by phenol/ chloroform/isoamyl alcohol method. The single step PCR-RFLP assay was used to differentiate the assemblages between A and B, which were found in humans. In this method, 432 bp expected size was amplified, and then for detection of subspecies, specific restriction RsaI and BspLI enzymes were used.Totally 34 samples were positive in terms of Giardia cyst out of 720 examined samples microscopically, so the parasite spread rate is reported 4.72%. Analysis PCR-RFLP on these samples revealed that 28 samples (93.3% have the genotype BIII and 2 samples (6.7% belong to the subgroup BIV.PCR-RFLP is a proper analytical method for determining the genotype among parasite types, using the glutamate dehydrogenizes zone's genes. Based on the results, an animal origin of infection cycle is suggested.

    Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic viral disease that is asymptomatic in infected livestock, but causes a serious threat to humans with a mortality rate up to 50%. Although the CCHF virus (CCHFV) is often transmitted by ticks, livestock-to-human and human-to-human transmission also occurs. In the current study, we focused on CCHF in the province of Isfahan, located in the center of Iran and deemed to be the second most infected province. Human and livestock sera and resident ticks in the livestock are collected from different regions of the province and analyzed with specific IgG ELISA and RT-PCR tests. Overall, 12% and 12.7% of studied human and livestock populations were IgG positive, respectively. The genome of CCHFV was detected in 9% of ticks resident in livestock involved in this survey. The CCHFV isolates from infected ticks were genetically examined. Nucleotide sequence of the S-segment revealed that the different isolates were closely related to each other, with nucleotide sequence identities higher than 98%. Phylogenetic analysis demonstrated that a variant isolate clustered with the Iraq strain. This high proportion of IgG-positive sera and nearly high proportion of infected ticks increases the risk of CCHF outbreaks in the province and probably posits a great danger to other provinces.

    Full Text Available Gavdel intrusive body, situated in NW Iran and NE of Uromieh-Dokhtar zone, is a part of Garehdagh, South-Arminian Zone (Arasbaran. The major outcrops of intrusive include of granodiorite, monzonite accompanied with granodioritic dyke. The studied samples display granular texture with essential minerals of, plagioclase, K-feldspar, amphibole ± quartz ± clinopyroxene. Geochemically, the studied rocks characterized by SiO2 in the range of (59.1-67.8%, Al2O3 (14.09-18.3%, high Sr (507.18-1150 ppm content , high ratios of Sr/Y (32.93-83.54, La/Yb and low Y (12.05-16.13 contents, which can indicate the adakitic characters of studied rocks. These features of Gavdel intrusive display geochemical similarity with high SiO2 adakites (HAS that comprise enriched LREE, LILE and depleted HFS elements such as Ta, Nb, and Ti. The fractionated REE pattern and low HREE and Y amount can be related to the occurrence of garnet or amphibole in residual source of adakitic magmas. High content of Sr and depletion of Ta, Nb and Ti can be ascribed either to the absence of plagioclase and the presence of Fe-Ti oxides in melt residue or fractionation of titanomagnetite and amphibole minerals with respect to petrograhic indications. Subducted slab breaking off followed by its partial melting and the overlying sediments accompanied by crustal assimilation through magma rising generated the magma in the studied area and the NW of Iran.

    Landslides are identified as one of the most important natural hazards in many areas throughout the world. The essential purpose of this study is to compare general linear model (GLM), general additive model (GAM), multivariate adaptive regression spline (MARS), and modified analytical hierarchy process (M-AHP) models and assessment of their performances for landslide susceptibility modeling in the west of Mazandaran Province, Iran. First, landslides were identified by interpreting aerial photographs, and extensive field works. In total, 153 landslides were identified in the study area. Among these, 105 landslides were randomly selected as training data (i.e. used in the models training) and the remaining 48 (30 %) cases were used for the validation (i.e. used in the models validation). Afterward, based on a deep literature review on 220 scientific papers (period between 2005 and 2012), eleven conditioning factors including lithology, land use, distance from rivers, distance from roads, distance from faults, slope angle, slope aspect, altitude, topographic wetness index (TWI), plan curvature, and profile curvature were selected. The Certainty Factor (CF) model was used for managing uncertainty in rule-based systems and evaluation of the correlation between the dependent (landslides) and independent variables. Finally, the landslide susceptibility zonation was produced using GLM, GAM, MARS, and M-AHP models. For evaluation of the models, the area under the curve (AUC) method was used and both success and prediction rate curves were calculated. The evaluation of models for GLM, GAM, and MARS showed 90.50, 88.90, and 82.10 % for training data and 77.52, 70.49, and 78.17 % for validation data, respectively. Furthermore, The AUC value of the produced landslide susceptibility map using M-AHP showed a training value of 77.82 % and validation value of 82.77 % accuracy. Based on the overall assessments, the proposed approaches showed reasonable results for landslide

    Introduction: We evaluated the association between four polymorphisms in the CRP gene with serum C-reactive protein (CRP) levels, prevalence and severity of coronary artery disease (CAD) in type 2 diabetes mellitus (T2DM) patients. Methods: We performed coronary angiography for 308 T2DM patients and classified them into two groups: T2DM with CAD and T2DM without CAD. All patients were from Ahvaz, Iran. serum levels of CRP, glucose and lipid profile were measured. Genotyping was performed by PCR/RFLP, and the severity of coronary artery disease was determined by Gensini score. Results: The GG genotype of SNP rs279421 was associated with the increased risk of CAD (OR= 2.38; 95% CI: 1.12- 5.8; p= 0.02) and CA, TT, TA genotypes and A allele of SNP rs3091244 and GA genotypes and A allele of SNP rs3093062 were significantly associated with increased CRP levels. None of genotypes or alleles was associated with Gensini score. We found that the haplotype 7 (AGCG) was associated with decreased risk of CAD (OR= 0.11; 95% CI: 0.02, 0.66; p= 0.017) and the Gensini score was correlated with increased levels of CRP, only in CAD group. Conclusion: Although genetic polymorphisms were influenced on serum RP levels, none of the alleles and genotypes raising or falling C-reactive protein levels was consistently associated with an increased prevalence of CAD or protected from that.

    Classifications of Archaeological discoveries are an essential feature for better interpretation of the extractive data from a case excavation. The question that will be focused on in this paper is; which of the parameters – raw materials or manufacturing processes – have changed during the time in an ancient archaeological place. The materials used in this research are ceramic pieces from archaeological excavations carried out in Haft-Tappeh, south-western Iran that chronologically belonging to the middle Elamite period (1500 B.C.). Samples classified firstly by their exterior characters. According to obtained results from quantitative X-ray diffraction and phase refining by Rietveld, it has become possible to characterize the data for clustering the samples in different groups. Observation by polarized light microscopy produced additional information about the manufacturing as well as the processing of the different admixtures used by ancient potters. Mineralogical- chemical interpretation of ceramics based on x-ray methods proved a dissimilar thermal behaviour due to different fabrication conditions during the same period. The results provided principally information on the existence of a common raw material reservoir but different manufacturing technique in pottering during middle Elamite period in Haft-Tappeh.

    A diversity of virulence factors work together to create the pathogenicity of Staphylococcus aureus. These factors include cell surface components that promote adherence to surfaces as well as exoproteins such as Panton-Valentine leukocidin (PVL), encoded by the luk-PV genes, that invade or bypass the immune system and are toxic to the host, thereby enhancing the severity of infections caused by methicillin-resistant Staphylococcus aureus (MRSA). The aim of this study was to determine the frequency of PVL-positive MRSA strains by real-time PCR and their antibiotic susceptibility patterns by phenotypic test. In total, 284 Staphylococcus isolates, identified by phenotypic methods from clinical samples of Shahrekord University Hospitals, Shahrekord, Iran, were tested for nuc, mecA, and PVL genes by TaqMan real-time PCR. The antibiotic susceptibility patterns of PVL-containing MRSA strains were determined via the disk diffusion method. In total, 196 isolates (69%) were nuc positive (i.e., S. aureus); of those isolates, 96 (49%) were mecA positive (MRSA). Eighteen (18.8%) of the 96 MRSA positive and 3 (3%) of the 100 methicillin-susceptible Staphylococcus aureus (MSSA) strains were PVL positive. PVL-positive MRSA strains were mostly recovered from tracheal specimens. Eight PVL-positive MRSA strains were resistant to all the tested antibiotics except vancomycin. A significant correlation (P = 0.001) was found between the mecA positivity and the presence of luk-PV genes. Community acquired (CA)-MRSA is becoming a public health concern in many parts of the world, including Asian countries. The variable prevalence of luk-PV-positive MRSA isolates in different regions and their rather high frequency in pneumonia necessitate the application of rapid diagnostic methods such as real-time PCR to improve treatment effectiveness.

    Full Text Available Purpose: To evaluate colistin use according to global standard drug consumption in intensive care units of a referral hospital in Shiraz, Iran Methods: A prospective, interventional study was performed during an 11 month period on 100 patients admitted to ICUs of a teaching hospital being treated with colistin for at least 3 subsequent doses. Required demographic, clinical, and paraclinical data were gathered by a pharmacist. Fifteen indexes were considered to evaluate colistin use. A clinical pharmacist reviewed indication and dose of colistin at the time of prescribing this agent. Results: In our study population, pneumonia (69% was the main indication of colistin. In 87% of patients, colistin administration was based on microbiological laboratory evidence. Continuation of therapy was inappropriate in 5% of cases. By the intervention of the clinical pharmacist, colistin was discontinued in all patients in whom empirical therapy was continued incorrectly. None of the patients received loading dose of colistin. The maintenance dose, dose interval, and duration of treatment of colistin were appropriate in 76%, 71%, and 100% of patients, respectively. For none of the patients, the pharmacokinetic dosing method was used. In all patients, serum creatinine and WBC count were evaluated on daily basis. The sum indexes of colistin use were relevant to standard guidelines in 67.33% of the cases.Conclusion: The results of this study highlight the necessity of the pharmaceutical care team participation in all stages of treatment with antibiotics. After pharmacist interventions, some criteria of colistin utilization were corrected and brought closer to standard values.

    Full Text Available The Nanmushu carbonate-hosted Zn-Pb deposit is located in the Mayuan district of Shaanxi Province, a newly discovered metallogenic district next to the Sichuan Basin, in the northern margin of the Yangtze Block, which is the largest and the only one that is currently mined in this district. The δ34S values of sulfides are characterized by positive values with a peak around +18‰, and the reduced sulfur may have derived from reduction of SO42- from paleoseawater or evaporitic sulfates that have possibly been leached by basinal brines during mineralization stage. Detailed fluid inclusion study shows two types of fluids in the sphalerite, quartz, dolomite, calcite and barite, that is, aqueous-salt dominant inclusions (type I and hydrocarbon-bearing inclusions (type II. The Laser Raman spectroscopy study shows occurrence of certain amount of CH4, C4H6, and bitumen. The salinities show similar values around 6 to 12 wt% NaCl equivalent but a decreasing temperature from early to late stages (typically 200° to 320°C in stage I, 180° to 260°C in stage II, and 140° to 180°C in stage III. These features may be related to basinal brines mixing between an external higher salinity CaCl2  ±  MgCl2-rich fluid and a local H2O-NaCl methane-rich fluid.

    Full Text Available Introduction Pyrite is the most abundant sulfide mineral in low sulfidation ore deposits. Experimental studies have shown that low-temperature ( 200°C from hydrothermal or metamorphic fluids (Butler and Rickard, 2000. Framboidal pyrite mostly occurs in sedimentary environments, though it could also form during metamorphism and hydrothermal alteration (Scott et al., 2009. The pyrite formed tends to be enriched in various trace elements such as Au and As. For this study we have combined the geology, alteration, mineralization with recent studies of the description of the deposit from core logging and underground mapping and geochemistry in the CheshmehZard gold district and also investigated the compositional variation and textural differences between pyrite types. This study is based on the results of our alteration and mineralization mapping and detailed logging of 1937.8 m of drill core. Materials and Methods Geology, hydrothermal alteration and mineralization were examined in drill holes along several cross sections. Host-rock alteration minerals and veins were determined for 11 samples using standard X-ray diffraction (XRD and X-ray fluorescence spectrometry (XRF techniques. Polished sections were studied by reflected light microscopy and backscattered electron images (BSE. In this study, the trace-element composition of pyrite samples from the Au-III vein system was obtained using electron microprobe analyzer (EMPA data. All analyseswere carried out at the department of Materials Engineering and Physics of the University of Salzburg in Austria. The EMPA measurements and BSE imaging were made using a JXA-8600 electron microprobe. Spot analyses of 30 pyrite grains from CheshmehZard are given in Table 1. Results The study area is located in the north of Khorasan Razavi Province 45 km to the south of Neyshabour. The area near CheshmehZard could become important as a site of economically significant gold mineralization. Six gold-bearing vein

    Full Text Available Abstract: Hepatitis C virus (HCV infection as an awesome medical issue is one of the most important pathogens of the human. Youngsters with thalassemia who get visit blood transfusions will be endangered with a high danger of HCV contamination. The point of this review is to decide the predominance of HCV disease among thalassemia patients in Abadan, Khuzestan region that is situated in the south-west of Iran. For this study a specific questionnaire on demographic information (Demographic information, for example, age, number of blood transfusions were acquired from patient records in which completed by trained personnel and also blood samples were taken at the same time in order to check the presence and amount of anti-HCV-Ab as a result, it showed that 11.17% (179/20, 11.17% of samples were positive. The HCV contamination is an illness which influences the extensive number of thalassemia patients in the world. The Lack of knowledge about blood safety of HCV contamination as the most predominant transfusion-transmitted sickness of blood in thalassemia patients is a major threat to public health in a group of countries in which the most obtained data from this region came from provinces of Iran. The anti-HCV prevalence in patients with thalassemia who live in Khuzestan province is less than other provinces of Iran and also neighbor countries and researchers should be paid attention to hepatitis C infection in order to prevent thalassemia cases.

    Full Text Available The Chadormalu magnetite-apatite deposit in Bafq metallogenic province, Central Iran, is hosted in the late Precambrian-lower Cambrian volcano-sedimentary rocks with sodic, calcic, and potassic alterations characteristic of iron oxide copper-gold (IOCG and iron oxide-apatite (IOA ore systems. Apatite occurs as scattered irregular veinlets and disseminated grains, respectively, within and in the marginal parts of the main ore-body, as well as apatite-magnetite veins in altered wall rocks. Textural evidence (SEM-BSE images of these apatites shows primary bright, and secondary dark areas with inclusions of monazite/xenotime. The primary, monazite-free fluorapatite contains higher concentrations of Na, Si, S, and light rare earth elements (LREE. The apatite was altered by hydrothermal events that led to leaching of Na, Si, and REE + Y, and development of the dark apatite. The bright apatite yielded two U-Pb age populations, an older dominant age of 490 ± 21 Ma, similar to other iron deposits in the Bafq district and associated intrusions, and a younger age of 246 ± 17 Ma. The dark apatite yielded a U-Pb age of 437 ± 12 Ma. Our data suggest that hydrothermal magmatic fluids contributed to formation of the primary fluorapatite, and sodic and calcic alterations. The primary apatite reequilibrated with basinal brines in at least two regional extensions and basin developments in Silurian and Triassic in Central Iran.

    Facies models try to explain facies architectures which have a primary control on the subsurface heterogeneities and the fluid flow characteristics of a given reservoir. In the process of facies modeling, geostatistical methods are implemented to integrate different sources of data into a consistent model. The facies models should describe facies interactions; the shape and geometry of the geobodies as they occur in reality. Two distinct categories of geostatistical techniques are two-point and multiple-point (geo) statistics (MPS). In this study, both of the aforementioned categories were applied to generate facies models. A sequential indicator simulation (SIS) and a truncated Gaussian simulation (TGS) represented two-point geostatistical methods, and a single normal equation simulation (SNESIM) selected as an MPS simulation representative. The dataset from an extremely channelized carbonate reservoir located in southwest Iran was applied to these algorithms to analyze their performance in reproducing complex curvilinear geobodies. The SNESIM algorithm needs consistent training images (TI) in which all possible facies architectures that are present in the area are included. The TI model was founded on the data acquired from modern occurrences. These analogies delivered vital information about the possible channel geometries and facies classes that are typically present in those similar environments. The MPS results were conditioned to both soft and hard data. Soft facies probabilities were acquired from a neural network workflow. In this workflow, seismic-derived attributes were implemented as the input data. Furthermore, MPS realizations were conditioned to hard data to guarantee the exact positioning and continuity of the channel bodies. A geobody extraction workflow was implemented to extract the most certain parts of the channel bodies from the seismic data. These extracted parts of the channel bodies were applied to the simulation workflow as hard data

    Full Text Available Background: Despite the progress made, animal bites and rabies are one of the important health problems in the country. The purpose of this study was to investigate the epidemiology of animal bites and rabies during 2004-2014 in Lorestan Province to prevent them in population of the province for the future prospective aspects. Materials and Methods: In a descriptive cross-sectional study, all those cases bitten in the province, during 2004 and 2014, were studied. The required information about the age, sex, the bitten organ, type of the invasive animal time, and location of the event were collected in questionnaires and then analyzed. Results: The total number of cases of animal rabies during the period of study was 43,892, shown at the rate of 223.23 in 100,000 people. Seventy-eight percent of animal bites in rural areas, 41.42% in the ages 10-29-year-old, 26.8% of cases were students, 56.77% leg bites, and 82.5% of dog bites. Four cases of human rabies were observed during this period. Conclusions: Rate of animal bites and rabies is high in Lorestan Province. Controlling animals such as dogs and cats in the province through training people at risk, especially among the students, rural areas and inter-sectorial coordination to eliminate stray animals should be considered over and over. Preventive actions to avoid bites are a priority.

    Full Text Available Leptospirosis and brucellosis are common zoonosis that affect many species of mammals mostly causing economical losses. Further, very important fact is huge danger for human and animal health around the world. The purpose of the study is to determine the prevalence of Brucella spp. and Leptospira spp. using multiplex polymerase chain reaction (mPCR method, in blood samples collected from cattle, sheep and goats. In this study, a total number of 250 blood samples (5 cc of blood with ethilen diamin tetra asetic acid were collected randomly from 100 cattle, 80 sheep and 70 goats located on 6 herds in Chaharmahal Va Bakhtiari and Esfahan provinces, Iran. After DNA extraction and setting of mPCR for Brucella spp. and Leptospira spp. mPCR products were screened. The DNA of these microorganisms was detected by multiplex PCR from 31 and 21 out of 100 cattle, respectively. Four of 70 goat’s blood samples from goat breeding farms were positive for Leptospira spp. and 11 were positive for Brucella spp. Out of 80 sheep blood samples 23 were positive for Brucella spp. and 14 for Leptospira spp. The results of the present study show ruminant as an important reservoir for transmission of these zoonotic diseases to humans in Iran. mPCR has the ability to concurrently detect both Brucella and Leptospira species from blood samples of ruminants. The convenience and the possibility of detection of both bacteria at a time, strongly support the use of this mPCR for routine diagnostics.

    Southwest Asia, which support 1/3 of the world's population, is acutely aware of the consequences of rapid and excessive population growth. No other region has consciously devoted so much of its resources to stemming excessive population growth. India, with a population of 684 million, formulated a policy of population limitation in the 1950s. The 1980 government rededicated itself to voluntary family planning and rebuilt the broad coalition of an excellent infrastructure of government institutions, voluntary organizations, and international agencies. Government support for family planning clinics began in Bangladesh in the 1960s. A strong institutional structure has been established under the supervision of the National Population Council. Innovative approaches to family planning service delivery have been initiated by an admirable array of institutions. Pakistan's Population Welfare Plan provides substantial funds and an administrative structure to make maternal/child helath care and family planning services available in rural areas. Another welfare program encourages smaller families through projects to enhance the status of women by improving literacy, establishing rural industries, and advocating late marriage. Nepal has had to struggle with a poor administrative structure, grossly insufficient medical services, and an inadequate database for policy formulation. Family planning services are now a component of the overall health program. The family planning services of the pioneer Afghan Family Guidance Association, established in 1968, have been incorported into the national maternal/child health program. The present government of Iran views foreign assistance as an unacceptable form of persuasion and has phased out all international funded family planning programs. Sri Lanka is the only country in the region to have made the demographic transition to fertility decline. An impressive health infrastructure delivers family planning services at every level using

    Full Text Available Background: The androgen receptor (AR gene contains a polymorphic trinucleotide repeat that encodes a polyglutamine tract in its N-terminal transactivation domain (NTAD. We aimed to find a correlation between the length of this polymorphic tract and azoospermia or oligozoospermia in infertile men living in Khuzestan, Iran. Materials and Methods: In this case-control study during two years till 2010, we searched for microdeletions in the Y chromosome in 84 infertile male patients with normal karyotype who lived in Khuzestan Province, Southwest of Iran. All cases (n=12 of azoospermia or oligozoospermia resulting from Y chromosome microdeletions were excluded from our study. The number of CAG repeats in exon 1 of the AR gene was determined in 72 patients with azoospermia or oligozoospermia and in 72 fertile controls, using the polymerase chain reaction (PCR and polyacrylamide gel electrophoresis. Results: Microdeletions were detected in 14.3% (n=12 patients suffering severe oligozoospermia. The mean CAG repeat length was 18.99 ± 0.35 (range, 11-26 and 19.96 ± 0.54 (range, 12-25 in infertile males and controls, respectively. Also in the infertile group, the most common allele was 19 (26.38%, while in controls, it was 25 (22.22%. Conclusion: Y chromosome microdeletions could be one of the main reasons of male infertility living in Khuzestan Province, while there was no correlation between CAG length in AR gene with azoospermia or oligozoospermia in infertile men living in Khuzestan, Iran.

    In recent years, much attention has been paid to occupational stress, but relatively little or no research has been conducted on the influence of knowledge, attitude, and practice of radiation protection (RP-KAP) on job stress among radiation workers. This study aims to assess job stress among health care workers in Iran who are occupationally exposed to radiation in order to determine the effects of KAP on self-protection against radiation on their job stress. The population in this descriptive cross-sectional study comprised 670 healthcare workers, including 428 staff with a degree in radiology and 242 other medical personnel who were working in 16 hospitals affiliated with Tehran University of Medical Sciences (TUMS) in Tehran, Iran. The census method was used to sample the workers. In total, 264 staff with a degree in radiology and 149 other medical personnel completed the job content questionnaire (JCQ) and the RP-KAP questionnaire from May to November 2014. The prevalence rate of job stress was 22.5% based on calculation formulas and possible scores on the JCQ. Sex, RP-knowledge, attitude, practice, and in-service training predicted 41.8% of the variance in job stress. According to the results of the binary logistic regression, workers with higher scores on knowledge (OR = 0.82, 95% CI: 0.75 - 0.90), attitude (OR = 0.71, 95% CI: 0.63 - 0.82), and practice (OR = 0.78, 95% CI: 0.72 - 0.86) and those who had participated in training programs had significantly lower rates of job stress (OR = 0.51, 95% CI: 0.28 - 0.93). The effects of RP knowledge, attitude, and practice on job stress were significant. In order to reduce job stress in radiation environments, ongoing training programs related to self-care and protection principles are recommended.

    Full Text Available Background: Anecdotal information has suggested that sodium benzoate is used with more than permissible doses during production steps of food products especially pickles and pickled cucumbers in food producing factories in Markazi province and other food producing factories . The present study was done to evaluate factual concentration of sodium benzoate in these products. Methods: In this study, 8 samples from canned pickled cucumbers and 10 samples from canned pickles were randomly gathered from food production factories in Markazi province between March and September 2010. Also, 25 samples from canned pickled cucumbers and 15 samples from canned pickles and 7 samples of bulk cargo pickled cucumbers were collected from the other provinces in Arak city. Sodium benzoate level was determined in the samples using UV-VIS spectrophotometry method. The determined values were analyzed by N-par test using SPSS software version 16.0. Results: Sodium benzoate level was near zero in the samples of canned pickles and pickled cucumbers from producing factories. This was 200-400 PPM in 7 samples from bulk cargo pickled cucumbers which was higher than permissible dose. There was not a statistically significant difference between mean benzoate level of canned pickles and pickled cucumbers produced in Markazi providence factories and other food factories. Benzoate level was significantly higher than permissible dose in bulk cargo pickled cucumbers. Conclusion: Food products from production factories do not have higher than permissible level of sodium benzoate; however, this is higher in bulk cargo pickled cucumbers. Hence, stricter control on bulk cargo pickled cucumber products is recommended.

    Full Text Available Background: The Fasciola trematodes are the most common liver flukes, living in a range of animals with global distribution and resulting in profound economic loss and public health challenges. Previous studies have indicated that the sequences of the second internal transcribed spacer (ITS-2 of ribosomal DNA (rDNA provide reliable genetic markers for molecular systemic studies of Fasciola. Objectives: The objective of the present study was to characterize Fasciola samples from different geographical regions of Sistan and Balouchestan province using sequences of second internal transcribed spacer (ITS-2 of ribosomal DNA (rDNA. Materials and Methods: Twenty adult trematodes were collected from the livers of slaughtered infected cattle. Total genomic DNA was extracted and ITS-2 rDNA targets were amplified by polymerase chain reaction (PCR. All samples were sequenced and investigated using the ClustalW2 sequence alignment tool and MEGA software. The sequences of some Iranian and non-Iranian isolates were used for comparison, in order to evaluate the variation in sequence homology between geographically different trematode populations. Results: The results of comparing the ITS-2 sequences with the BLAST GenBank database showed one type of sequence for F. hepatica and three different types of sequences for F. gigantica in the specimens. Conclusions: The present study demonstrated that Fasciola samples from cattle in two geographical locations in Sistan and Balouchestan province represented no genetic diversity in F. hepatica and high genetic variation in F. gigantica.

    Full Text Available The aim of the study was to evaluate and compare the efficiency and practicality of seven trapping methods for adult phlebotominae sand flies. The results of this investigation provide information to determine the species composition and nocturnal activity pattern of different sand fly species.The study was carried out in both plain region (about 5km far from northeast and mountainous region (about 40km far from southwest of Kashan City. Seven traps were selected as sampling methods and sand flies were collected during 5 interval times starting July to September 2011 and from 8:00PM to 6:00AM in outdoors habitats. The traps include: sticky traps (4 papers for 2 hours, Disney trap, Malaise, CDC and CO2 light traps, Shannon traps (black and white nets and animal-baited trap.A total of 1445 sand flies belonging to 15 species of Phlebotomus spp. and five of Sergentomyia spp. were collected. Females and males comprised 44.91% and 55.09% of catches, respectively. Of the collected specimens, Se. sintoni was found to be the most prevalent (37.86% species, while Ph. papatasi, accounted for 31.76% of the sand flies.Disney trap and sticky traps exhibited the most productivity than other traps. In addition, in terms of the efficiency of sampling method, these two trapping methods appeared to be the most productive for both estimating the number of sand flies and the species composition in the study area.

    It is important to study the status and trend of soil contamination with trace elements to make sustainable management strategies for agricultural soils. This study was conducted in order to model zinc (Zn), copper (Cu), and nickel (Ni) accumulation rates in agricultural soils of Kermanshah province using input and output fluxes mass balance and to evaluate the associated uncertainties. The input and output fluxes of Zn, Cu, and Ni into (from) the agricultural soils of Kermanshah province via livestock manure, mineral fertilizers, municipal waste compost, pesticides, atmospheric deposition, and crop removal were assessed for the period 2000-2014. The data were collected to compute the fluxes at both township and regional scales from available databases such as regional agricultural statistics. The basic units of the balance were 9 townships of Kermanshah province. Averaged over the entire study region, the estimated net fluxes of Zn, Cu, and Ni into agricultural soils were 341, 84, and131 g ha year(-1), with a range of 211 to 1621, 61 to 463, and 114 to 679 among the townships. The livestock manure was responsible for 55, 56, and 67 % of the total Zn, Cu, and Ni inputs at regional scale, while municipal waste compost and mineral fertilizers accounted for approximately 19, 38, and 15 % and 24, 4, and 14 % of the total Zn, Cu, and Ni inputs, respectively. Atmospheric deposition was a considerable source only for Ni and at township scale (7-29 % of total Ni input). For Zn, Cu, and Ni, the input-to-output ratio of the fluxes ranged from 1.8 to 48.9, 2 to 48.2, and 4 to 303 among townships and averaged 2.8, 3, and 9 for the entire study area, respectively. Considering that outputs other than with crop harvests are minor, this means that Zn, Cu, and Ni (in particular Ni) stocks are rapidly building up in soils of some parts of the study region. Uncertainties in the livestock manure and crop removal data were the main sources of estimation uncertainty in this study

    We studied the safety of a trivalent inactivated surface antigen (split virion, inactivated) influenza vaccine, Begrivac® (Novartis Company), widely used in health care workers in Kurdistan. A longitudinal follow-up study was performed in Sanandaj city, west of Iran, recruiting 936 people. A questionnaire was completed for each participant, and all symptoms or abnormal physical findings were recorded. In part 1 of the study, the post-vaccination complaints were headache (5.3%), fever (7.9%), weakness (9.6%), chills (10.1%), sweating (10.5%), arthralgia (20.2%), and malaise (21.5%). Swelling of the injection site was seen in 267 (30.3%) participants, and pruritus of the injection site was seen in 290 (32.9%) participants. Redness and induration were also reported in 42.5% of the participants. Local reactions were mainly mild and lasted for 1-2 days. No systemic reactions were reported in the second part of the study. None of the participants experienced any inconvenience. We concluded that local adverse reactions after the trivalent inactivated split influenza vaccine, Begrivac®, in health care workers were far more common than expected. Continuous surveillance is needed to assess the potential risks and benefits of newly produced influenza vaccines.

    To assess molecular characterization, distribution, seasonal activities of sandfly species and Leishmania parasites infecting them for this zoonotic cutaneous leishmaniasis focus. The collections were carried out in 2009-2011 using CDC traps, Sticky Papers and manual aspirator in and around the villages in Abarkouh district. Individual sandflies were characterized by PCR amplification and sequencing of fragments of their mitochondrial cytochrome b gene. Leishmania parasite infections within sandflies were performed by targeting Cyt b, ITS-rDNA, k-DNA and microsatellite genes. The PCR assays detected only Leishmania major (L. major). All infections (30) were found in the abundant and widespread vector Phlebotomus papatasi (P. papatasi). Small numbers of other sandfly species were also screened for infections, but none was found. Sergentomyia sintoni and P. papatasi were the predominant members in all locations of this district and in all habitats throughout the trapping season. Only five other sandfly species were found, namely Phlebotomus ansari, Phlebotomus caucasicus, Phlebotomus sergenti, Sergentomyia dentata and Sergentomyia merviney. In the current survey, the only infections detected are of L. major in females of P. papatasi (30 out of 190). The rates of infection of P. papatasi by L. major are not significantly different in compare with other locations in Iran with no diversity of parasite strains. Zoonotic cutaneous leishmaniasis may have emerged only recently in Abarkouh district, and the reason may well be the instability of the transmission cycles there.

    Full Text Available Background: Around 2000 plant species occur naturally in Lorestan Province of which 250 species are medicinal and myrtle is one of them. Myrtle is a shrub whose leaves and fruits have medicinal value and thus, if managed and harvested properly, could produce sustained economic benefits. In recent years, however, over half of the myrtle site areas was destroyed, due to inappropriate management and excessive harvesting practices. Thus, coming up with a practical harvesting approach along with identifying those factors damaging the sites, seems to be very crucial. Methods: In our investigation, we calculated the conservation value per hectare of myrtle in the Dooreh forest area in Lorestan Province. Using the Contingent Valuation (CV and Double Bounded Dichotomous Choice (DBDC methods, we determined the willingness to pay (WTP for myrtle conservation. The WTP was estimated with a logit model for which indices were obtained based on a maximum precision criterion. Results: The results showed that 86.67 per cent of people were willing to pay for the conservation of these myrtle sites. Average monthly WTP per family was calculated as $0.79. The annual conservation value in terms of WTP for the preservation of the myrtle sites in Dooreh was estimated as $102,525. Among the variables of the model presented, education had a positive impact, while the amount proposed for payment and family size had a negative impact on the WTP. Conclusions: Our estimate of the value of myrtle conservation should provide justification for policy makers and decision making bodies of natural resources to implement policies in order to conserve the natural sites of this species more effectively. Keywords: Conservation value, Myrtle, Contingent valuation method, Double Bounded Dichotomous method, Logit model

    Full Text Available Background:intestinal parasitic infection is one of the most prevalent health problems in developing countries. This study was conducted to determine the prevalence of intestinal parasitic infection and its correlation with socio-demographic parameters in Haji-abad, 2015.MaterialsandMethods:This cross-sectional descriptive study was conducted on 635 samples. After completing questionnaires, stool samples were assessed macroscopically, and microscopically using direct slide smear with saline and lugol, formalin-ether concentration, Ziehl-Neelsen staining to track Cryptosporidium species and Trichrome staining for the samples suspected to amoeba and other indeterminate cases. PCR using specific primers was conducted for Entamoebahistolytica/E. dispar suspected samples. The results were analyzed using SPSSver.16 software.Results:Of total 635 samples, 198 cases (31.2% were infected by at least one intestinal parasite. The most common parasites in this area were: Blastocystis sp. (105, 16.5%, Endolimax nana (43, 6.8%, Entamoeba coli (32, 5.0%, Giardia lamblia (31, 4.9%, and Iodamoeba butschlii (11, 1.7%. Enterobius vermicularis (1, 0.2% was the only detected helminthic infection. Regarding socio-demographic variables, age, residence, sampling month, and job showed a significant correlation with IPIs (p-value=0.031, 0.019, 0.014, 0.012; respectively. None of nine microscopically suspected E. histolytica/E. dispar cases were confirmed by molecular investigations (PCR method and were considered as E. coli.Conclusion:In agreement with previous studies, helminthes infections show a dramatic decline compare to protozoa in this study. The relatively high incidence of intestinal protozoan infections in studies performed in Iran supports strategies for pre­venting the transmission and expansion of these parasites as a priority.
