Abstract
Despite the strict environmental management regulations, there is still a considerable adverse impact on the ecosystem and human health when it comes to large-scale gold mining operations. Gold mining is an energy-intensive process that can discharge substantial quantities of chemicals combined with gaseous emissions into the environment. Considering gold mining's significant role in Nevada's economy and the growing concern about climate change, it's necessary to investigate the environmental burdens of this sector. To provide a comprehensive environmental perspective on the large-scale gold mining operations in Nevada, this study used a life cycle assessment (LCA) approach to evaluate the environmental burdens of gold production from double refractory ores in the roasting process. The Tool for Reduction and Assessment of Chemical and Other Environmental Impacts (TRACI) method was used to evaluate the categories of acidification, ozone depletion, global warming, smog, carcinogenics, non-carcinogenics, respiratory effects, and fossil fuel depletion. Results showed that major contributors to greenhouse gas (GHG) emissions were grinding and off-gas treatment stages being responsible for 34.80 % and 56.10 % of the total global warming, respectively. The carbon footprint for producing one kg of gold was 12,200 kg CO2-eq. Sensitivity analysis was also employed on electricity to observe the influence of electricity on key contributor stages. A 10 % change in electricity reduced the GHG emissions in crushing and grinding by 12.2 % and 7.10 %, respectively, while delivering an insignificant effect on the off-gas treatment. Significantly, this study stands as the first initiative to apply LCA in the North American mining industry, with a unique focus on the off-gas treatment post-roasting and its associated emissions. Our findings can serve as a foundational database, aiding stakeholders in making informed decisions and enhancing sustainable practices in the gold mining industry.

Abstract
Lidocaine toxicity is caused by unintended intravascular injection or overdose. Lidocaine is metabolized in the liver by the CYP3A4 isoenzyme. The objective was to investigate if the administration of rifampin could accelerate animal recovery and reduce the symptoms of lidocaine toxicity by induction of the CYP3A4. Thirty-six male rats were divided into control and treatment groups, each containing three subgroups. The treatment group received oral rifampin suspension daily for 1 week. In all rats, 2.00% lidocaine was injected intravenously. The first subgroup was monitored for neurological symptoms. In the second subgroup, data were recorded after the electrode was placed in the right hippocampus. Electrocardiograms were taken from the third subgroup. CYP3A4 was measured using an ELISA kit. Neurological recovery was seen after 22 and 15 min in the control and treatment groups, respectively. Rifampin also caused a significant reduction in amplitude and number of field action potentials compared to the control group. Numerous cardiac arrhythmias were observed in the control group. The mean level of CYP3A4 in the treatment group was significantly higher than in the control group. In conclusion, oral rifampin could increase the synthesis of CYP3A4, therefore, the animal recovery from lidocaine toxicity was accelerated.

Abstract
Actions that are taken to preserve effective antibacterial agents and eliminate transmission of resistant organisms are crucial to prevent a catastrophic postantibiotic era. In this systematic review, we searched and appraised relevant texts and expert opinions to determine effective strategies to tackle bacterial resistance worldwide. We considered expert opinions, consensus, current discourses, comments, assumptions or assertions and discussion papers published in English. We searched following databases for expert opinion-based literature: MEDLINE, CINAHL, ISI Web of Knowledge, SCOPUS, Cochrane Central Register of Controlled Trials and World Health Organization (WHO). We extracted the textual data from texts using a standardised data extraction tool. Textual pooling was not possible, so the conclusions were presented in a narrative form. Eighteen texts were included in this review. The findings show that, the most repeated policies and strategies include implementing and strengthening bacterial resistance surveillance, developing national guidelines, improving public awareness; enhancing home and everyday life hygiene; improving prescribing patterns, improving laboratories capacity, promoting innovation and research in new drugs and technology and strengthening coordination. This review systematically gathered strategies that were recommended by textual publications. To our knowledge, this was the first systematic review of text and opinion in the field of bacterial resistance. These results can be used by policymakers, hospital managers, and governments, alongside the results of quantitative and qualitative systematic reviews.

Abstract
Naturally occurring Babesia bigemina infection in cattle is associated with changes in the status of oxidative stress, trace elements, sialic acid, and cholinesterase activity in blood. However, to date there is no description of hepatic damage in the infected animals. More importantly, the majority of the above-mentioned causative factors are synthesized or stored in the liver. Therefore, this study was undertaken to evaluate biomarkers of hepatic function, paraoxonase-1 activity, and lipid profile in 13 cattle infected with B. bigemina which did not respond to standard treatment. The animals were necropsied and the histopathology of the liver and DNA damage of hepatocytes were examined. Blood analysis revealed a significant parasitemia burden-dependent increase in the activities of hepatic enzymes and total bilirubin and a decrease in albumin concentrations in the infected cattle compared to the control ones. Paraoxonase-1 activity was remarkably lower in the infected animals than the control. A significant decrease in the blood concentrations of total cholesterol, low density lipoprotein, and high density lipoprotein and a significant increase in the triglyceride concentration were observed in the infected animals. Severe oxidative damages were also recorded in the haptic tissue evidenced by significant alterations in the activities of antioxidant enzymes, suppression of total antioxidant capacity, and oxidation of biomolecules. Congestion of blood vessels, bile duct hyperplasia, and hepatocyte necrosis were the evident histopathologic findings. Our results revealed significant changes in the indices of liver function in the diseased cattle, leading to the conclusion that the parasite can potentially cause liver dysfunction.

Abstract
An 11-year-old Hanoverian gelding used for jumping was evaluated for gait abnormalities and hoof problems in the hindlimbs. Clinical examinations revealed signs consistent with shivers. A thyroid gland enlargement was noticed, baseline serum thyroid hormone (TH) concentrations were low, and a low response to thyrotropin-releasing hormone administration was observed. Hypothyroidism was suspected. The horse was treated with levothyroxine for 1 year. TH concentrations returned to the normal range by week 4 of treatment. Thirty weeks after the initiation of levothyroxine therapy, the gait abnormality improved. Our findings suggest that the assessment of thyroid status and especially of the subclinical thyroid gland disorders in horses affected with shivering, as well as evaluation of the effects of levothyroxine on the improvement of clinical signs could be promising in establishing the aetiopathogenesis and/or treatment of shivering in horses.

Abstract
Many biological mechanisms including cellular metabolism and cell death are regulated by mitochondria known as powerhouse of the cell. Recently, let-7b, a tumour-suppressor microRNA has been detected in mitochondria of human cells targeting several mitochondrial-encoded respiratory chain genes. Triphenylphosphonium cation (TPP) is one of the major classes of mitochondriotropics that possess the ability of specifically targeting the mitochondria. PAMAM dendrimers are one of the most available agents in gene delivery due to their well-defined and beneficial features such as large density of surface functional groups. Hyaluronic acid (HA), a natural polysaccharide has been demonstrated to have the abilities such as good biocompatibility and targeting CD44 overexpressed receptors on non-small cell lung cancer (NSCLC) cells. In this research, let-7b-PAMAM (G5)-TPP and let-7b-PAMAM (G5)-TPP-HA nano-carriers were designed to deliver let-7b miRNA mimic to NSCLC cells' mitochondria as a novel way of cancer cells inhibition. Nano-carriers were capable of being successfully taken up by A549 cells and localised in mitochondria environment. Let-7b loaded nanoparticles reduced cell viability and induced apoptosis significantly. Expression of genes involved in mitochondrial oxidative function was decreased resulting in nanoparticles effect on mitochondria. Application of mitochondria targeted-miRNA delivery systems could regulate cellular functions to inhibit lung cancer.

Abstract
Alzheimer's disease (AD) is a major global health priority and providing an efficient way for early diagnosis of people developing dementia is important. The Mini-Mental State Examination (MMSE, total score = 30) and Test Your Memory (TYM, total score = 50) are widely used as screening tests for cognitive function. In the present study 174 subjects including healthy people (CON group) and those having Alzheimer's disease (AD group) were introduced to MMSE and TYM cognitive tests adjusted to Iranian population. Sensitivities and specificities with optimal cut-off scores, area under curve (AUC), positive predictive value (PPV) and negative predictive value (NPV) were measured for both tests. The MMSE scores of the CON and AD groups were 23.77 ± 0.327 and 10.88 ± 0.762, respectively. The TYM scores were 44.32 ± 0.389 and 14.37 ± 1.368 in the CON and AD participants, respectively. Findings in the MMSE test were: AUC = 0.962, optimal cut-off score = 18.5, sensitivity = 0.90 and specificity = 0.96. Values in the TYM test were: AUC = 0.991, optimal cut-off score = 31, sensitivity = 0.90 and specificity = 1. We found no correlation between the cognitive performance and age in the CON group but a positive correlation in the AD patients. On the other hand, t-test analysis indicated that achievement of the test scores are significantly sex dependent, with more scores attained by the females. Taken together, in regard to correct classification rate (CCR); the TYM test seems to be more appropriate for cognitive screening in our study. However, considering an analogous AUC, both tests are comparable and have high sensitivity and specificity for discriminating between people with and without AD.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Trachyspermum ammi has been used traditionally as a popular ethnobotanical plant in human and animal parasitic infestations. Few scientific studies have been conducted on in vitro anthelmintic activity of T. ammi against various helminths and there is no study on its in vivo/in vitro anthelmintic properties against equine helminths. AIM OF THE STUDY The present study aimed to evaluate in vivo anthelmintic activity of crude powder (CP) and crude aqueous extract (CAE) of T. ammi seeds against gastrointestinal nematodes in the donkey. MATERIALS AND METHODS Thirty donkeys, naturally and severely infected with Strongyle-type nematodes, were randomly divided into six groups and administered orally with graded doses of CP and CAE at single dose as follow: Two groups were treated with 1 and 3 gkg-1 body weight of CP, two groups were treated with CAE at the equivalent dose rate 1 and 3 gkg-1 bw of CP and one group was treated with 200 μgkg-1 bw of Ivermectin 0.2% (Positive Control). One group received no medication (Negative Control). Efficacy was determined by faecal egg count reduction (FECR) test. The faecal samples were taken from the donkeys on days 7, 14 and 28 post-treatments (PT) and the egg per gram (EPG) of faeces was determined for each animal. FECR for donkeys treated with CP, CAE, and Ivermectin 0.2% was calculated on days 7, 14, and 28 PT. In the present study, CAE was analyzed using gas chromatography-mass spectrometry (GC-MS) to determine CAE chemical components. High-performance liquid chromatography (HPLC) using a marker (thymol) was applied to confirm the existence of thymol as an active principle. RESULTS Based on the FECR findings, the maximum FECR (71.2%) was observed in the group treated with CAE3 on day 14 PT, while it was 66.2% for CP3 on the same day. The effects of different treatments (P < 0.001), time (P < 0.001) and their interactions (P < 0.05) on EPG showed a significant difference. A dose-dependent response in the anthelmintic activity of CP and CAE was observed. GC-MS analysis indicated that thymol was the major component of CAE (Area = 45.01%) with the respective peak at retention times (Rt) 10.41 min. On HPLC analysis of CAE, thymol was found to be the major constituent of CAE (Area = 58.76%) with the same Rt at 13.233 min. CONCLUSION The present study indicated that both CP and CAE of T. ammi had the dose-dependent anthelmintic effects. Due to the development of drug resistance against synthetic anti-helminthics, T. ammi seems to be a promising alternative for the treatment and prevention of helminths in livestock.

Abstract
INTRODUCTION Lack of a clear policy for the development of health human resources has created inconsistencies. These imbalances are threats to the health system to achieve its goals. Therefore, the development of human resources through proper performance of higher education health system is an important part of the policy development process of the health sector. The present paper aims to introduce the methods applied for the compilation of evolution and innovation program of medical sciences training as well as the most important directions for evolution and innovation. METHODS In this study, we evaluated the methodology for designing packages of Iran's higher education health system evolution and innovation. For this purpose, the evaluation of the policy process was conducted based on Michelle and Scott's policy process models. This policy evaluation model starts by problem identification and definition and continue by agenda setting, policy formation, legitimation, implementation, evaluation, and policy modification, using the proper feedback. Qualitative content analysis method was used as a research method for subjective interpretation of the content of the text data. RESULTS Twelve policies, 68 strategies and their translation in the health system were adopted in a comprehensive plan for higher health education. Eleven practical packages were also developed in order to implement these policies as packages for reform and innovation in medical education. These packages were organized based on the IPOCC pattern. CONCLUSIONS The lack of a comprehensive look at each project or program could bring about irreparableness consequences. However, the MoHME of Iran, relying on the integration of health higher education with health care system and comprehensive method used for transformation and innovation plan in the field of health higher education could take an important step towards improving the nation's health.

Abstract
BACKGROUND Transfusion-transmitted virus (TTV) is a single-stranded DNA virus. Renal transplant patients have a higher risk of TTV infection. OBJECTIVE To evaluate the prevalence of TTV and its correlation with post-renal transplantation complications in a population of Iranian patients. METHODS A cross-sectional study was performed on 120 renal transplant recipients. TTV infection in the peripheral blood samples was detected by semi-nested polymerase chain reaction (semi-nested PCR). Then, the relationship between TTV and renal post-transplant complications was examined. RESULTS 34.2% renal transplant recipients were positive for TTV. There was a significant correlation between the presence of TTV and diabetes, acute transplant rejection, and urinary tract infection. We did not find any direct correlation between the presence of TTV infection and hypertension, hyperlipidemia, respiratory tract infection, and cytomegalovirus infection. CONCLUSION We found an increased rate of TTV infection in renal transplant recipients associated with post-transplantation complications. TTV may be an important risk factor for some post-renal transplantation complications.

Abstract
Aim: The present study aimed to detect Babesia ovis and Babesia motasi in the blood samples of sheep and goats from Northwest of Iran by the semi-nested polymerase chain reaction (PCR) technique. Materials and Methods: A total of 166 whole blood samples (including 123 sheep and 43 goats) were collected. In the first stage, the PCR was performed to amplify a piece of 18S rRNA gene of Babesia and Theileria genera. Then, semi-nested PCR was carried out on all PCR products to differentiate B. ovis and B. motasi. Results: The PCR indicated that totally, 19 (11.44%) out of 166 samples were positive for Babesia or Theileria spp. The semi-nested PCR showed that 38 samples (22.89%) were positive only for B. ovis. No significant association was found between the infection rate of B. ovis and age, gender and species of animals. Conclusion: In the present study, there was no evidence for B. motasi infection in small ruminants from Northwest of Iran. Therefore, B. ovis was the main causative agent of ovine Babesiosis in this region.

Abstract
Objective Opium is a narcotic drug that is commonly abused. The prescription of pharmaceutical derivatives of opium is limited due to their possible harmful effects on the body's metabolism and tolerability by patients. The aim of the present study was to evaluate the effects of chronic opium consumption on some sexual and thyroid hormones in diabetic and non-diabetic male and female rats. Material and Methods This experimental study was conducted on 56 Wistar rats. The animals were divided into diabetic addicted (DA), diabetic non-addicted (DNA), non-diabetic addicted (NDA) and non-diabetic non-addicted (NDNA) groups of male and female rats. Peripheral blood samples were collected to measure the thyroid and sex hormone levels. Student's t-test was used to compare the mean values of the hormones between two groups. Results T3 serum level in male addicted groups significantly increased in comparison with non-addicted ones in both diabetic and non-diabetic groups. The testosterone level of male rats decreased due to the consumption of opium while it was significantly increased in diabetic and NDNA female rats in comparison with non-addicts. In DNA female animals, the mean level of 17-hydroxyprogesterone increased significantly compared with non-diabetic groups, however, it decreased in addicted females (diabetic and non-diabetic) in comparison with non-addicts. The level of DHEA-S increased significantly in diabetic and NDA male rats as compared with the non-addicted group. Conclusion Opium affects the endocrine system in a sex-dependent manner, and opium could have different effects in diabetic and non-diabetic conditions.

Abstract
BACKGROUND Cytomegalovirus (CMV) is the most common opportunistic viral infection in kidney transplant recipients. CMV classification is usually based on its glycoprotein B (gB) genotypes, which divides the virus into 4 strains (gB1-4). OBJECTIVE To determine the incidence of CMV genotypes in Iran and their relation to various clinical factors. METHODS We studied 80 renal transplant recipients admitted to our transplant referral center between 2014 and 2015. All of the studied patients were monitored every 1-2 weeks for CMV infection by immunofluorescence method. There were 34 CMV-infected patients whose sera were studied with sequencing technique to identify the 4 CMV genotypes. All patients were followed up to 6 months after transplantation. RESULTS gB1 was the most common genotype (35.3%); it was followed by gB3 and gB4 (each with 17.6 %), gB2, and mixed gB1,3 and gB1,2 (each with 14.7%). Age (p=0.037), time of infection after transplantation (p=0.011), and biopsy-proven rejection (p=0.012) were associated with CMV genotype. After adjusting for covariates, significant associations were found between genotype gB1 and family relationship (p=0.047) as well as HLA mismatch (p=0.014); genotype gB3 and family relationship (p=0.011); and genotype gB4 and age (p=0.019). CONCLUSION The most common CMV gB genotype in CMV-infected kidney transplant recipients in Iran was gB1. We recommend considering related therapeutic applications in the management of such patients.

Abstract
INTRODUCTION Academic institutions are the most important organizations for implementation of internationalization policies and practices for integrating an international, intercultural and global dimension in higher education system. Also, a globally increasing demand for higher education has been seen in the past two decades so that the number of students enrolled in higher education institutions in the worldwide nation-states has increased dramatically. The National Plan of International Development of Medical Education was designed with the aim of identifying available potentials in all the universities of medical sciences, encouraging the development of international standards of medical education, and planning for the utilization of the existing capacity in Islamic republic of Iran. METHODS Authors have tried to review the several aspects of international activities in higher education in the world and describe national experiences and main policies in globalization of medical education in Iran within implementation of the National Plan for Development and Innovation in Medical Education. RESULTS The findings of some global experiences provide the policy makers with clear directions in order to develop internationalization of higher education. CONCLUSION The Program for International Development of Medical Education was designed by the Deputy of Education in the Ministry of Health and the effective implementation of this Program was so important for promotion of Iranian medical education. But there were some challenges in this regard; addressing them through inter-sectoral collaboration is one of the most important strategies for the development of internationalization of education in the field of medical sciences.

Abstract
Nanoscaled quantum dots (QDs), with unique optical properties have been used for the development of theranostics. Here, InP/ZnS QDs were synthesised and functionalised with folate (QD-FA), D-glucosamine (QD-GA) or both (QD-FA-GA). The bi-functionalised QDs were further conjugated with doxorubicin (QD-FA-GA-DOX). Optimum Indium to fatty acid (In:MA) ratio was 1:3.5. Transmission electron microscopy (TEM) micrographs revealed spherical morphology for the QDs (11 nm). Energy-dispersive spectroscopy (EDS) spectrum confirmed the chemical composition of the QDs. MTT analysis in the OVCAR-3 cells treated with bare QDs, QD-FA, QD-GA, QD-FA-GA and QD-FA-GA-DOX (0.2 mg/mL of QDs) after 24 h indicated low toxicity for the bare QDs and functionalised QDs (about 80-90% cell viability). QD-FA-GA-DOX nanoparticles elicited toxicity in the cells. Cellular uptake of the engineered QDs were investigated in both folate receptor (FR)-positive OVCAR-3 cells and FR-negative A549 cells using fluorescence microscopy and FACS flow cytometry. The FA-functionalised QDs showed significantly higher uptake in the FR-positive OVCAR-3 cells, nonetheless the GA-functionalised QDs resulted in an indiscriminate uptake in both cell lines. In conclusion, our findings indicated that DOX-conjugated FA-armed QDs can be used as theranostics for simultaneous imaging and therapy of cancer.

Abstract
BACKGROUND Multiple applications of antipsychotic agents are the main obstacle in the treatment of schizophrenia. Due to behavioral abnormalities, low compliance is observed in most of the psychotic patients. Designing of new drug delivery systems to overcome compliance problem seems to be necessary. In situ forming implants are a suitable choice for the delivery of antipsychotic agents due to their easy administration process and sustained release kinetics. OBJECTIVE In this study, a novel poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) based nanoporous in situ implant system is developed for delivery of aripiprazole. METHODS Entrapment efficiency, drug loading, rheological features, morphological characteristics and release profile of nano-porous in situ implant system are analyzed in this study. RESULTS Entrapment efficiency and drug loading coefficient were modeled and impact of different experimental parameters was analyzed using D-optimal study. Entrapment efficiency and drug loading were optimized at 99.32% and 75.23%, respectively. Rheological analyses demonstrated that the developed formulation is a highly cross-linked gel with possible capability for controlled delivery of aripiprazole. According to the FTIR studies, aripiprazole was intact within polymer networks. SEM and light microscopic analyses proved the acceptable morphological characteristics of in situ gels. Release studies demonstrated a biphasic pattern of release. After initial burst release, a sustained pattern was observed for 18 days. The release data was fitted to Korsmeyer-Peppas model and release pattern was found out to be Fickian. In addition, the release profile was compared with novel pluroniccarrageenan based hydrogel system. CONCLUSION PHBV based in situ forming implant seems to be a novel formulation for delivery of Aripiprazole.

Abstract
OBJECTIVE Data from multiple clinical trials, mostly conducted outside the US, indicate that probiotic prophylaxis is an effective intervention for prevention of necrotizing enterocolitis (NEC) in preterm infants. Probiotics are routinely used in many countries. However, in the US, probiotic use in preterm infants is limited (6.7% of very low birth weight (VLBW) infants in the US were exposed to probiotics in 2014, Vermont Oxford Network (VON)). Probiotic products are often considered in 'generic' terms, but considerable variation exists between commercially available probiotics in terms of their quantity and quality. The study objectives were to identify the probiotic products used in VLBW infants within the US, and to determine whether their use was supported by reliable evidence. STUDY DESIGN A phone survey of all neonatal intensive care units (NICU) participating in VON within the US was conducted between May and September 2015 to identify NICUs that are using probiotics in VLBW infants. Data was collected regarding specific probiotic brands, timing, dose and duration of probiotic use. An evidence based literature search, limited to randomized controlled trials in VLBW infants, was conducted to determine whether the use of identified probiotics were supported by reliable evidence. RESULTS There was a 70.3% (500/711) response rate to the phone survey. During the survey period, 14.0% of NICUs were using probiotics in VLBW infants (70/500). Probiotics were routinely given to all VLBW infants in 8.8% (44/500) NICUs, while it was given in selected VLBW infants in 5.2% (26/500) of NICUs. The common indications for selective use of probiotics were feeding intolerance and antibiotic use. Sixteen commercial probiotics products were identified through the phone survey. Probiotic products most commonly used were Culturelle (27.1%), Biogaia (14.3%), Gerber Soothe (14.3%) and Florababy (8.6%). The literature search identified evidence that evaluated 4/16 probiotic products identified (Culturelle, Align, Biogaia and ABC Dophilus). Only ABC Dophilus was reported to have a protective effect against NEC, but is used sparingly in US NICUs (2.9%). CONCLUSIONS The probiotics use in VLBW infants within the US is increasing, but is still limited. There was no evidence for safety or efficacy of 90% of the probiotics currently used in US NICUs, and therefore, caution is warranted.

There are few estimates of influenza burden in the WHO Region for the Eastern Mediterranean. In this study we estimated the burden of severe acute respiratory infection (SARI) and influenza-associated SARI (F-SARI) in selected provinces of Islamic Republic of Iran, the trends of SARI and confirmed cases of influenza (F-SARI) over 12 months (seasonality), and the age groups most at risk. Using the electronic Iranian influenza surveillance system and data of cases in sentinel hospitals of 3 selected provinces, we estimated the monthly trend (seasonality) of incidence for SARI and F-SARI, overall incidence of SARI and F-SARI and their disaggregation by age with the aid using the Monte Carlo technique. The age groups most at-risk were children aged under 2 years and adults older than 50 years.

Abstract
This study aimed to evaluate the effects of intravenous infusion of a soybean-based lipid emulsion on some blood energy-related metabolites and insulin sensitivity indexes in sheep. Four clinically healthy ewes were assigned into a 2-treatment, 2-period cross-over design. Either normal saline (NS) or lipid emulsion (LE) was intravenously introduced at a rate of 0.025 mL·kg(-1) min(-1) for 6 h. The concentrations of blood nonesterified fatty acid (NEFA), beta-hydroxybutyrate, triglyceride, cholesterol, urea, creatinine, cortisol, glucose, and insulin were measured at different time points. After 6 h, intravenous glucose tolerance test was performed. Lipid infusion elicited an increase (P < 0.05) in the NEFA, beta-hydroxybutyrate, and triglyceride concentrations compared with the baseline value and NS infusion. Infusion of NS did not influence blood glucose concentration; however, LE infusion increased plasma glucose concentration (P < 0.05). At time point 12 h, serum insulin concentrations were increased (P < 0.05) in NS treatment; however, such an increase was not observed in the LE treatment. Insulin sensitivity index for the LE infusion was lower (P < 0.05) than that for the NS treatment. The glucose effectiveness was not (P > 0.05) different among treatments. In the LE treatment, acute-phase insulin responses increased (P < 0.05) and disposition index decreased (P < 0.001) compared with NS treatment. The results showed that experimentally induced NEFA in blood could cause insulin resistance in sheep. The current model could be used to evaluate the pathogenesis of conditions associated with increased lipid mobilization and insulin resistance.

Abstract
BACKGROUND A pressure ulcer is a complication related to the need for the care and treatment of primarily disabled and elderly people. With the decrease of the blood flow caused by the pressure loaded, ulcers are formed and the tissue will be wasted with the passage of time. OBJECTIVE The aim of this study was to construct blood flow monitoring system on the heel tissue which was under external pressure in order to evaluate the tissue treatment in the ulcer. METHODS To measure the blood flow changes, three infrared optical transmitters were used at the distances of 5, 10, and 15 mm to the receiver. Blood flow changes in heels were assessed in pressures 0, 30, and 60 mmHg. The time features were extracted for analysis from the recorded signal by MATLAB software. Changes of the time features under different pressures were evaluated at the three distances by ANOVA in SPSS software. The level of significance was considered at 0.05. RESULTS In this study, 15 subjects, including both male and female, with the mean age of 54±7 participated. The results showed that the signal amplitude, power and absolute signal decreased significantly when pressure on the tissue increased in different layers (p<0.05). Heart rate only decreased significantly in pressures more than 30 mmHg (p=0.02). In pressures more than 30 mmHg, in addition to a decrease in the time features, the pattern of blood flow signal changed and it wasn't the same as no-load signal. CONCLUSION By detecting the time features, we can reach an early diagnosis to prognosticate the degeneration of the tissue under pressure and it can be recommended as a method to predict bedsores in the heel.

Abstract
BACKGROUND It has been suggested that shift work (SW) is associated with changes in blood pressure (BP). However, studies have reported contradictory results. AIMS To prospectively examine the association between SW and BP among male workers. METHODS A historical cohort study, involving workers of Esfahan's Mobarakeh Steel Company, in Iran, was conducted over 14 years. The association between SW, systolic BP (SBP) and diastolic BP (DBP) was investigated after adjusting for body mass index, age, work experience, marriage, smoking and education based on the Bayesian multilevel modelling approach. RESULTS The study sample included 5331 male workers. The mean age (standard deviation, SD) was 34.8 (6.6) years and mean work (SD) experience was 9.4 (6.1) years. Among these subjects, 2348 (44%), 340 (6%) and 2643 (50%) were day workers, weekly rotating shift workers and routinely rotating shift workers, respectively. The mean SBP (SD) and DBP (SD) of these workers were 118.7 (8.1) and 73.1 (6.7) mmHg, respectively. After controlling for several confounding variables, there was no significant relationship between SBP and DBP and SW. CONCLUSIONS No significant association between SW and BP was observed among these three groups (day workers, weekly rotating shift workers and routinely rotating shift workers). Prospective studies, which control for confounding factors, such as the healthy worker effect, occupational history, family history and psychological factors (e.g. occupational stress and job satisfaction), are required to evaluate this further.

Abstract
To evaluate the effect of intravenous infusion of a soybean based lipid emulsion (Lipovenoes 10%) on some blood constituents in sheep, a replicated 2 × 2 Latin square design experiment was conducted in four clinically healthy ewes. Lipid emulsion (LE group) or normal saline (NS group) was infused intravenously at a rate of 0.025 mL kg(-1) per min for 6 hr and the concentrations of blood triglyceride, glucose, insulin, calcium, magnesium, phosphorous, sodium and potassium were measured before (baseline) and then at timepoints 2, 4, 6, 12 and 24 hr after infusion. Compared to the baseline values and/or NS infusion, LE infusion resulted in a significant increase in the concentrations of triglyceride (p < 0.001), glucose (p < 0.01), calcium (p < 0.05), phosphorous (p < 0.01) and a significant decrease in insulin (p < 0.001) and magnesium (p < 0.05) concentrations. Compared to the baseline value, the homeostasis model of insulin resistance (HOMA-IR) index increased (p < 0.001) at timepoints 2 and 4 hr and abruptly decreased at timepoint six hr (p < 0.01) following LE infusion. In LE group, HOMA-IR values were significantly (p < 0.001) higher than those for NS group at timepoints 2 and 4 hr after infusion. Neither treatment nor time influenced serum sodium and potassium concentrations (p > 0.05). In conclusion, intravenous infusion of Lipovenoes temporarily influenced some blood constituents. Increased triglyceride concentrations were associated with an increase in HOMA-IR values indicating a state of insulin resistance. No remarkable adverse effect was observed following LE infusion and lipid based emulsions can be safely used in ruminants not suffering from extensive lipid mobilization.

Abstract
To evaluate the need for congenital rubella syndrome prevention in our national health programme we aimed to determine the rate of anti-rubella positivity in umbilical cord blood samples 8 years after measles-rubella mass vaccination in the Islamic Republic of Iran. In a cross-sectional study we tested umbilical cord blood samples for anti-rubella IgG and IgM by ELISA in 154 deliveries at a university hospital in Tehran. Overall 72.7% of umbilical cord blood samples were positive for anti-rubella lgG and 27.3% were negative. All of the samples were negative for anti-rubella IgM. In the samples with a history of mothers' rubella vaccination, only 87.5% were positive for anti-rubella IgG. The results suggest the need for another mass vaccination for rubella in women of child-bearing age and continuation of routine vaccination of infants, plus consideration of obligatory anti-rubella IgG testing before pregnancy in women who were not vaccinated and vaccination of women before marriage.

Abstract
Background Diabetes in humans induces chronic complications such as cardiovascular damage, cataracts and retinopathy, nephropathy and polyneuropathy. The most common animal model of human diabetes is streptozotocin (STZ)-induced diabetes in the rat. The present study investigated the effects of Nigella sativa hydroalcholic extract on glucose concentrations in streptozotocin (STZ) diabetic rats. Methods In this study Twenty-five Wister-Albino rats (aged 8-9 weeks and weighing 200-250 g) were tested. Rats were divided into five experimental groups (control, untreated STZ-diabetic (60 mg/kg B.W., IP), treated STZ-diabetic with hydroalcholic extract of Nigella Sativa (NS) (5 mg/kg B.W, IP), treated STZ-diabetic with hydroalcholic extract of NS (10 mg/kg B.W., IP) and treated STZ-diabetic with hydroalcholic extract of NS (20 mg/kg B.W., IP and 32 days were evaluated to assess its effect on fasting blood glucose (FBG), and in different groups fasting blood glucose (FBG) and body weight (BW) were measured in the particular days (1, 16 and 32). At the end of the study, the animals were fasted overnight, anaesthetized with an intraperitoneal injection of sodium pentobarbital (60 mg/kg), and sacrificed for obtaining tissues samples (liver, pancreases). The number of islets and cells were counted and the islet diameters were determined by calibrated micrometer. The glycogen content in the liver was examined by Periodic Acid-Schiff (PAS) staining. Results Treatment with NS (5 mg/kg b.w.) markedly increased BW gain and the FBG level was significantly (p<0.001) reduced when compared to the control. Histopathological examination showed that the NS (5 mg/kg b.w.) partially recovered hepatic glycogen content and protected the great deal of the pancreatic islet cells. The number of islets, cells and islets diameter were found statistically significant when compared to the control (p<0.01, p<0.05). Conclusions Higher doses of NS did not exhibit any therapeutic effect. These results showed that hydroalcholic extract of NS at low doses has hypoglycemic effect and ameliorative effect on regeneration of pancreatic islets and may be used as a therapeutic agent in the management of diabetes mellitus. The hypoglycemic effect observed could be due to amelioration of β-cell, thus leading to increased insulin levels. Consequently, N. sativa may prove clinically useful in the treatment of diabetics and in the protection of β-cells against streptozotocin.

Abstract
PURPOSE Non-viral vectors have been widely proposed as safer alternatives to viral vectors, and cationic polymers have gained increasing attention because they can form self-assembly with DNA. Chitosan is also considered to be a good candidate for gene delivery systems, since it is already known as a biocompatible, biodegradable, and low toxic material with high cationic potential. However, low solubility and transfection efficiency need to be overcome prior to clinical trial. In this work, we focus on alkyl modified chitosan which might be useful in DNA condensing and efficient gene delivery. METHODS N, N- Diethyl N- Methyl (DEMC) and N- Triethyl Chitosan (TEC) were synthesized from chitosan polymer. In order to optimize the polymers for gene delivery, we used FITC-dextran (FD). Then the optimized polymer concentrations were used for gene delivery. Fluorescent microscope was used, in order to evaluate the polymers' efficiency for gene delivery to human embryonic kidney epithelial cells (HEK 293T). RESULTS This modification increased chitosan's positive charge, thus these chitosan derivatives spontaneously formed complexes with FD, green fluorescence protein plasmid DNA (pEGFP), red fluorescence protein plasmid DNA (pJred) and fluorescent labeled miRNA .RESULTS gained from fluorescent microscope showed that TEC and DEMC were able to transfer FD, DNA and miRNA (micro RNA) to HEK cell line. CONCLUSION We conclude that these chitosan derivatives present suitable characteristics to be used as non-viral gene delivery vectors to epithelial cells.

Abstract
BACKGROUND Anthropometric data can be used to identify the physical dimensions of equipment, furniture, etc. The use of furniture that fails to fulfill the anthropometric data of its users has a negative impact on human health. Specific anthropometric dimensions are necessary to design school furniture. Anthropometric data have been measured in many communities especially among schoolchildren. There are different ethnic groups with probably different anthropometric data in Iran, and anthropometric data can change by time, so gathering data about anthropometric dimensions is important. This study was designed to obtain anthropometric dimensions of Iranian children (Fars ethnicity) aged 7-11 years. METHODS In a cross-sectional study in Yazd, Iran, descriptive statistics as well as key percentiles for 17 static anthropometric data of primary school students (1015 males and 1015 females), were measured and compared between boys and girls. RESULTS The age of the students was between 6 and 11 years. Mean weight was between 21.56±5.33 kg and 36.63±9.45 kg in boys and between 20.79±3.48 kg and 35.88±9.40 kg in girls. Mean height was between 1187/02±53.98 mm and 1420.83± 69.39 mm in boys and between 1173.90±51.01mm and 1421.27±70.82 mm in girls. There was also some difference in other anthropometric data between two genders. CONCLUSION Results of this study showed some differences in anthropometric data with other studies. We also observed significant gender differences in some dimensions as well.

Abstract
BACKGROUND High consumption of nonalcoholic beverages is one of the causes of dental erosion. Annual consumption of beverages in Iran is 48 LPCY (Lit per capita per year) that is equal to 144 bottles per capita in year and is relatively a high rate. Taking this into consideration, the present study was planned to determine the pH and fluoride content of beverages consumed in Kerman, south east of Iran. METHODS In a descriptive cross-sectional study during 2006-2007, samples of any type of beverages in Kerman were taken once every 4 months and each sample was examined for its acidity and fluoride content in ambient and refrigerator temperatures. A total of 744 experiments were conducted on 62 brands of beverages with different colors to determine the acidity and on 31 brands of beverages to determine their fluoride content. Acidity was determined by pH-meter in the ambient temperature and refrigerator temperature (+4◦C). Fluoride content was determined using specific electrode method. Data analysis was done by SPSS software package. RESULTS Mean acidity of the consumed beverages in Kerman was 2.55 and 2.78 mg/L in the ambient temperature and refrigerator temperature, respectively. Mean fluoride concentration in the temperature of the ambient and refrigerator were 1.13 and 1.27 mg/L respectively. Therefore beverages consumption in Kerman had a higher acidity than national standard. CONCLUSION Since some of the consumed beverages in Kerman are distributed and consumed in other parts of Iran as well, necessary precautions for controlling dental erosion especially in Kerman residents should be taken.

Abstract
BACKGROUND Leigh syndrome is an early onset, progressive, neurodegenerative disorder with developmental and motor skills regression. Characteristic magnetic resonance imaging abnormalities consist of focal bilateral lesions in the basal ganglia and/or the brainstem. The main cause is a deficiency in oxidative phosphorylation due to mutations in an mtDNA or nuclear oxidative phosphorylation gene. METHODS AND RESULTS A consanguineous Moroccan family with Leigh syndrome comprise 11 children, three of which are affected. Marker analysis revealed a homozygous region of 11.5 Mb on chromosome 20, containing 111 genes. Eight possible mitochondrial candidate genes were sequenced. Patients were homozygous for an unclassified variant (p.P193L) in the cardiolipin synthase gene (CRLS1). As this variant was present in 20% of a Moroccan control population and enzyme activity was only reduced to 50%, this could not explain the rare clinical phenotype in our family. Patients were also homozygous for an amino acid substitution (p.L159F) in C20orf7, a new complex I assembly factor. Parents were heterozygous and unaffected sibs heterozygous or homozygous wild type. The mutation affects the predicted S-adenosylmethionine (SAM) dependent methyltransferase domain of C20orf7, possibly involved in methylation of NDUFB3 during the assembly process. Blue native gel electrophoresis showed an altered complex I assembly with only 30-40% of mature complex I present in patients and 70-90% in carriers. CONCLUSIONS A new cause of Leigh syndrome can be a defect in early complex I assembly due to C20orf7 mutations.
