Abstract
Manipulation of the structure of covalent organic frameworks at the molecular level is an efficient strategy to shift their biological, physicochemical, optical, and electrical properties in the desired windows. In this work, we report on a new method to construct chiral triazine frameworks using metal-driven polymerization for enantiodiscrimination. The nucleophilic substitution reaction between melamine and cyanuric chloride was performed in the presence of PdCl2, ZnCl2, and CuCl2 as chirality-directing agents. Palladium, with the ability of planar complex formation, was able to assemble monomers in two-dimensions and drive the reaction in two directions, leading to a two-dimensional triazine network with several micrometers lateral size. Nonplanar arrangements of monomers in the presence of ZnCl2 and CuCl2, however, resulted in calix and bouquet structures, respectively. While 2D and bouquet structures showed strong negative and positive bands in the CD spectra, respectively, their calix counterparts displayed long-range weak negative bands. In spite of the ability of both calix and bouquet networks to load l-histidine 35 and 50% more than d-histidine from pure enantiomers, respectively, only calix counterparts were able to take up this enantiomer (78%) from the racemic mixture. The two-dimensional polytriazine network did not show any specific interactions with pure enantiomers or their racemic mixtures.

Abstract
Recovery of valuable metals via leaching printed circuit boards (PCBs) has gained moment recently. This work studied the Microbial fuel cell (MFC) performances for recovery of Cu from a Cu2+ solution by examining key operating parameters. A dual-chamber MFC with 6 cm × 6 cm × 7 cm dimensions was constructed. Both anode and cathode electrodes were made of a carbon cloth sheet. The anodic and cathodic chambers were separated by a Nafion membrane. The highest Cu recovery efficiency was 99.7% after 240 h batch mode operation, yielding 102 mW/m2 MFC power density output using 1 g/L Cu2+ solution as the catholyte (initial pH 3) and an anolyte containing 1 g/L sodium acetate inoculated with a sludge from a wastewater treatment plant's anaerobic pond, with 2 cm distance between the electrodes made of polyacrylonitrile polymer. The highest open circuit voltage, current density (based on cross-section cathode area) and power density with an external load of 1 kΩ was 555 mV, 347 mA/m2 and 193 mW/m2, respectively. Additionally, recovery of Cu in the leachate of PCBs using sulfuric acid leaching after 48 h was performed and the highest Cu recovery was 50% in 48 h.

Abstract
BACKGROUND AND AIMS Food processing changes the nature of foods, and it is growing globally due to its availability and affordability and its effects on the palatability of foods. Consumption of ultraprocessed foods (UPFs) may adversely affect weight gain. The purpose of the current study is to examine the association between UPFs consumption and adiposity among Iranian adults. METHODS AND RESULTS A cross-sectional study was conducted on 1459 Iranian adults (≥19 years). Dietary intakes were assessed using a validated 136-item food frequency questionnaire (FFQ), and foods were classified based on the NOVA system. Overweight, obesity, and abdominal obesity were defined as body mass index (BMI) ≥25 and < 30, ≥30, respectively, and waist circumference (WC) ≥91 for women and WC ≥ 89 for men. The odds of general and abdominal obesity across the quartiles of UPFs were assessed by binary logistic regression. UPFs consumption contributed to 20.17% of daily energy intake. After adjustment for potential confounders, UPFs consumption was not associated with general or abdominal obesity. However, in the fully adjusted model, men in the top quartile of UPFs were twice as likely to be overweight compared with those in the bottom quartile (OR = 2.06, 95% CI: 1.03, 4.10; P = 0.047). No association was found in women or stratified analysis by age. CONCLUSION The present findings suggest a sex-specific association between UPFs consumption and overweight. UPFs consumption might be associated with an increased risk of overweight in men, but no such association was found in women. Future cohort studies are required to confirm these results.

Abstract
OBJECTIVES This study aimed to summarise the effect of community-based intervention programmes on the prevention of cardiovascular disease (CVD) by reducing cardiometabolic risk factors. STUDY DESIGN This was a systematic review and meta-analysis. METHODS A systematic search in the PubMed database and screening of reference lists aimed to identify community-based CVD prevention programmes from inception up to April 2020. The mean differences and standard deviations for CVD risk factors, including blood pressure, lipid profile, blood glucose and body weight indices, were extracted and pooled using a random effects model. RESULTS Screening of 11,889 titles/abstracts and full texts resulted in 48 studies being included in this review. The meta-analysis showed that community-based programmes have led to considerable decreases in systolic blood pressure (weighted mean difference [WMD] = -2.90 mm Hg, 95% confidence interval [95% CI]: -3.63, -2.16), diastolic blood pressure (WMD = -2.21 mm Hg, 95% CI: -3.12, -1.29), serum levels of low-density lipoprotein cholesterol (LDL-C; WMD = -8.88 mg/dl, 95% CI: -12.84, -4.92), triglycerides (WMD = -8.40 mg/dl, 95% CI: -12.10, -4.70), total cholesterol (WMD = -2.96 mg/dl, 95% CI: -3.10, -2.81) and fasting blood glucose (WMD = -2.06 mg/dl, 95% CI: -3.02, -1.10). A moderate decrease in body weight was also found with community-based CVD prevention programmes. However, community-based CVD prevention programmes were not associated with any significant changes in serum levels of high-density lipoprotein. CONCLUSIONS The present study indicates that community-based strategies have successfully led to an improvement in CVD risk factors, particularly by reducing blood pressure, serum levels of LDL-C and triglycerides, obesity indices and blood glucose. The impact of these programmes on CVD is modified by the type of intervention and by different cultural and physical environments.

Abstract
BACKGROUND Self-harm-related death is one of the most unfortunate, tragic, and regrettable types of death owing to injuries with a variety of socio-economic and cultural causes. The study aimed to determine the trend in the mortality of self-harm by sex and age at national and provincial levels in Iran over a period of 26 years. METHODS The Iran Death Registration System (DRS), cemetery databanks in Tehran and Esfahan, and the national population and housing censuses of Iran were used for this study. Using a growth model, the population was estimated in the age groups. Incompleteness, misalignment, and misclassification in the DRS were all considered and addressed accordingly. We used a spatio-temporal and Gaussian process regression model to estimate mortality rates in children and adults. RESULTS Over the study period, 67,670 deaths were estimated owing to self-harm across the country. The overall age-standardized mortality rate decreased from 4.32 per 100,000 (95% unit interface (UI): 3.25-5.75) to 2.78 (2.15-3.59) per 100,000 between 1990 and 2015, a reduction of approximately 35.65%. The M/F ratio was 2.03:1 with an annual percent change of -2.38% and -1.37% for women and men, respectively. The annual self-harm mortality rate was higher among individuals aged 15-24 years, as well as it was more in men during the study period. CONCLUSION Mortality from self-harm has declined over the study period in Iran. Higher rates in men and in population aged 15-24 years, with considerable variation by province, were the distinguishing features of self-harm. Iran needs to improve monitoring through a comprehensive multisectoral strategy; and most importantly, provide timely, effective and low-cost preventive interventions.

Abstract
The aim of this study was to estimate the basic reproduction number (R0) of COVID-19 in the early stage of the epidemic and predict the expected number of new cases in Shahroud in Northeastern Iran. The R0 of COVID-19 was estimated using the serial interval distribution and the number of incidence cases. The 30-day probable incidence and cumulative incidence were predicted using the assumption that daily incidence follows a Poisson distribution determined by daily infectiousness. Data analysis was done using 'earlyR' and 'projections' packages in R software. The maximum-likelihood value of R0 was 2.7 (95% confidence interval (CI): 2.1-3.4) for the COVID-19 epidemic in the early 14 days and decreased to 1.13 (95% CI 1.03-1.25) by the end of day 42. The expected average number of new cases in Shahroud was 9.0 ± 3.8 cases/day, which means an estimated total of 271 (95% CI: 178-383) new cases for the period between 02 April to 03 May 2020. By day 67 (27 April), the effective reproduction number (Rt), which had a descending trend and was around 1, reduced to 0.70. Based on the Rt for the last 21 days (days 46-67 of the epidemic), the prediction for 27 April to 26 May is a mean daily cases of 2.9 ± 2.0 with 87 (48-136) new cases. In order to maintain R below 1, we strongly recommend enforcing and continuing the current preventive measures, restricting travel and providing screening tests for a larger proportion of the population.

Abstract
OBJECTIVE The potentiality to switch between yeast and hyphal morphologies plays an important role in the virulence of Candida albicans (C. albicans). The objective of the present study was to evaluate the chemical composition, antifungal activity and influence of propolis upon germ tube formation of C. albicans clinical isolates. METHODS The major compounds of propolis ethanolic extract (PEE) was revealed by gas chromatography-mass spectrometry (GC/MS) analysis. Broth microdilution method was used for determination of minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) of this extract. C. albicans isolates were exposed to sub-MIC concentrations of propolis and germ tube reduction percent (GRP) and morphological transition from yeast to filamentous form were monitored microscopically. RESULTS Phenolic compounds, aromatic acids, aliphatic acids, sugars and polycyclic aromatic hydrocarbons were the major compound classes in PEE. Mean of MIC and MFC values of PEE against C. albicans isolates were 360.6μg·mL-1 and 1250.1μg·mL-1, respectively. The increase in concentration led to a significant reduction in germ tube formation, so mean of GRP was 36.7±11.1 and 22±10.1 at concentration of ½ MIC and ¼ MIC of PEE, respectively. CONCLUSIONS In conclusion, the present study indicated that PEE has interesting potential as a therapeutic agent that targets germ tube formation by C. albicans as a critical virulence factor.

Abstract
INTRODUCTION Diabetes mellitus is an important public health challenge worldwide. The prevalence of type 2 diabetes varies across countries. The aim of this study is to estimate the prevalence of type 2 diabetes and to determine related factors including socioeconomic factors in a large random sample of Tehran population in 2011. METHODS In this cross-sectional study, 91,814 individuals aged over 20 years were selected randomly based on a multistage, cluster sampling. All participants were interviewed by trained personnel using standard questionnaires. Prevalence and Townsend deprivation indexes were calculated. Principal component analysis (PCA) was used to construct wealth index. Logistic regression model was used in multivariate analysis. RESULTS The estimated prevalence of self-reported diabetes was 4.98 % overall, 4.76 %in men and 5.19 % in women (P < 0.003). In multivariate analysis, age, marital status (married and divorced/widow) and BMI were positively associated with the prevalence of self-reported diabetes. Of the socioeconomic variables, educational level and wealth status were negatively and Townsend Index was positively associated with diabetes. CONCLUSION Our study findings highlight low reported prevalence of diabetes among adults in Tehran. Subjects with low socioeconomic status (SES) had a higher prevalence of type 2 diabetes. Weight gain and obesity were the most important risk factors associated with type 2 diabetes. Wealth index and educational level were better socioeconomic indicators for presenting the inequality in diabetes prevalence in relation to Townsend deprivation index.

Abstract
BACKGROUND Lung cancer is one of the most common causes of death that is rising in many countries including Iran. This study aimed to determine the impact of factors on survival of lung cancer patients at a referral center of lung diseases in Tehran, Iran. MATERIALS AND METHODS A retrospective study was conducted on adult lung cancer cases admitted to a referral center for lung diseases from 2011 to 2015. Multivariate analysis was performed to determine the risk factors for all-cause mortality. RESULTS Of a total 933 patients with lung cancer, 53.4% died, 49.3% of them at the hospital. Overall median follow-up time was 7 months. The most common histological type of cancer was adenocarcinoma with a 13 month median survival time. Age ≥55 and smoking remained significant for all-cause mortality on Cox analysis, whereas gender was not. CONCLUSIONS The survival of lung cancer patients is poor and the patients with history of smoking and age ≥55 are at increased risk of death. Having a large hospital-based registry provides a good measurement of prognostic statistics for lung cancer. Further investigations are necessary to establish reasons for mortality.

Abstract
A total of 72 laying hens were used to investigate the effect of probiotic and lactose on body weight loss, tibia ash, antibody production against sheep red blood cell (SRBC), heterophile-to-lymphocyte (H/L) ratio and gut microbiota in a common moulting method for 14 d. Hens were randomly allocated to 6 experimental groups consisting of (i) full feed (FF), (ii) feed withdrawal (FW), (iii) FW with calcium (Ca), (iv) FW with Ca and offering 7 g/lit lactose in drinking water (CaL), (v) FW with Ca and offering 1 g/lit probiotic in drinking water (CaP), and (vi) FW with Ca and offering a mixture of lactose and probiotic in drinking water (CaLP). The results showed body weight loss in all FW groups were more than 25% that was significantly higher than FF group (p < 0.05). The relative organ weights of hens in FW groups were lower than FF group; especially, it was significant for liver and ovary (p < 0.05). No significant difference was observed between all groups for tibia ash. The highest H/L ratio was related to FW group and offering Ca and lactose numerically and probiotic alone significantly resulted in decrease of this ratio (p < 0.05). The results also showed no significant difference for antibody production against SRBC among experimental groups. The highest coliform bacteria numeration observed in FW group and lactose could significantly reduce this population (p < 0.05). Lactic acid bacteria (LAB) numeration demonstrated a significant difference among treatments, so that FF hens had higher LAB than others (p < 0.05). In addition, FW moulted hens had significantly lower LAB compared to other moulted hens (p < 0.05), except for Ca group. In conclusion, probiotic and lactose was effective in maintaining caecal microbiota balance and improving immunity in hens exposed to moulting.

Abstract
Computational simulations have the potential to aid understanding of cardiovascular hemodynamics under physiological conditions, including exercise. Therefore, blood hemodynamic parameters during different heart rates, rest and exercise have been investigated, using a numerical method. A model was developed for a healthy subject. Using geometrical data acquired by echo-Doppler, a two-dimensional model of the chamber of aortic sinus valsalva and aortic root was created. Systolic ventricular and aortic pressures were applied as boundary conditions computationally. These pressures were the initial physical conditions applied to the model to predict valve deformation and changes in hemodynamics. They were the clinically measured brachial pressures plus differences between brachial, central and left ventricular pressures. Echocardiographic imaging was also used to acquire different ejection times, necessary for pressure waveform equations of blood flow during exercise. A fluid-structure interaction simulation was performed, using an arbitrary Lagrangian-Eulerian mesh. During exercise, peak vorticity increased by 14.8%, peak shear rate by 15.8%, peak cell Reynolds number by 20%, peak leaflet tip velocity increased by 47% and the blood velocity increased by 3% through the leaflets, whereas full opening time decreased by 11%. Our results show that numerical methods can be combined with clinical measurements to provide good estimates of patient-specific hemodynamics at different heart rates.

Abstract
The Islamic Republic of Iran, in her 20 year vision by the year 2025, is a developed country with the first economic, scientific and technological status in the region, with revolutionary and Islamic identity, inspiring Islamic world, as well as effective and constructive interaction in international relations. Enjoying health, welfare, food security, social security, equal opportunities, fair income distribution, strong family structure; to be away from poverty, corruption, and discrimination; and benefiting desirable living environment are also considered out of characteristics of Iranian society in that year. Strategic leadership towards perceived vision in each setting requires restrictive, complete and timely information. According to constitution of National Institute for Health Researches, law of the Fifth Development Plan of the country and characteristics of health policy making, necessity of designing a Health Observatory System (HOS) was felt. Some Principles for designing such system were formulated by taking following steps: reviewing experience in other countries, having local history of the HOS in mind, superior documents, analysis of current production and management of health information, taking the possibilities to run a HOS into account. Based on these principles, the protocol of HOS was outlined in 3 different stages of opinion poll of informed experts responsible for production on management of information, by using questionnaires and Focus Group Discussions. The protocol includes executive regulations, the list of health indicators, vocabulary and a calendar for periodic studies of the community health situation.

Abstract
A new kinetic method has been developed for the determination of iodine in water samples. The method is based on the catalytic effect of I(-) with the oxidation of Indigo Carmine (IC) by KBrO(3) in the sulfuric acid medium. The optimum conditions obtained are 0.16 M sulfuric acid, 1 × 10(-3) M of IC, 1 × 10(-2) M KBrO(3), reaction temperature of 35°C, and reaction time of 80 s at 612 nm. Under the optimized conditions, the method allowed the quantification of I(-) in a range of 12-375 ng/mL with a detection limit of 0.46 ng/mL. The method was applied to the determination of iodine in river and city water samples with the satisfactorily results.

Abstract
BACKGROUND Life expectancy at birth as an alternative summary measure of mortality represents number of years which a newborn will be alive based on the current age specific death rates. As it summarizes death rates across all age range in a given population is the most common summary measure of mortality. The aim of this study was to correct death rates for underreport and estimate life expectancy at birth in rural population of Iran in 2008. In addition, this study aimed to assess the Vital Horoscope system's data quality. METHODS Data were obtained from all Health Houses in Iranian villages in 2008. In order to adjust over 5 years old death rates for underreport, we used Brass Growth Balance method. Since this method is not applicable to under 5 years old, we used child mortality rates projected based on the Iranian Demographic and Health survey 2000 to correct death rates. RESULTS Adjusted life expectancy at birth for males was 71.5 year and for females was 74.4 year. Completeness of the death data was 88% for males and 79% for females. Adjusted child (under 5) mortality rate by sex in males and females was 25.9 and 23.8 per 1000 live births respectively. Adult mortality for males was 167.2 and 98.3 for females per 1000. CONCLUSION Data based on Vital Horoscope system are a suitable source to estimate life expectancy and other mortality statistics. Also has an acceptable completeness on death registration. Further studies to investigate accuracy of data from the Vital Horoscope system are suggested.

Abstract
BACKGROUND It is estimated that about 370 million people are chronic carriers of HBV worldwide. Apparently 3% of Iranian populations are chronic carriers of this virus. We aimed to evaluate the viral DNA in biological fluids of chronic hepatitis patients compared to a control group. METHODS The current case-control study was designed to evaluate the viral DNA in biological fluids of 70 chronic hepatitis patients compared to a control group using ELISA, PCR and Real Time. RESULTS All individuals (100%) in case group were HBsAg positive while in control group only 2 individuals (2.8%) were HBsAg positive. Three individuals, in control group were positive using PCR and Real Time PCR indicating that about 7% of those in control group were chronic carriers of HBV. The interesting point was the copy of viral DNA; (5.49 ×10(4), 2.162×10(3) and 7.26×10(6)) for 3 chronic carriers using sera while it was about (5.71×10(3), 1.45×10(2) and 2.56×10(5)) using ear cerumen confirming the necessity of investigating for the carriers of HBV in different biological fluid and by different methods. CONCLUSION It can be concluded chronic carriers of hepatitis B are much more than what is diagnosed by routine diagnostic tests. On the other hand ELISA alone can not be relied on as a complete test for screening of chronic carriers in hepatitis B. PCR and Real Time PCR are more reliable tests for this purpose.

Abstract
Merozoite surface protein 2 (MSP-2), a very immunogenic malaria antigen, is a highly polymorphic 45-53 kDa merozoite surface protein, which is regarded as a promising vaccine candidate. The highly polymorphic nature of MSP-2 suggests that the molecule can be involved in protective immunity against malaria. The antibody responses to MSP-2 antigen are mostly directed against polymorphic and dimorphic regions of the protein. The current study aimed at testing the reactivity of human sera from a malaria-endemic area of Gambia against MSP-2 regions 2, 3 and 4 compared to crude schizont extract in a period of 20 years. The age-dependent immunity was analysed in a manner of cross-sectional study (the data of the first visit) and also a longitudinal study design (analysing the data at four different time points from 1960 to 1980) testing the sera of 178 individuals randomly selected from the Keneba Serum Collection by using MSP-2 recombinant protein. The total IgG responses were measured by ELISA. Kolmogorov-Smirnov was used to check the normal distribution of OD, Hb and parasitaemia, and then Spearman correlation was applied to analyse the data. Most sera recognized, predominantly, the variable regions of the MSP-2, particularly the domain 3. The IgG response against all the antigens increased with age. The IgG responses against domain 3 of MSP-2 were associated with an increase in haemoglobin levels but a decrease in parasitaemia, suggesting that this immune response may be one of the most useful means for further studies on protective immunity against malaria.

Abstract
The aim of this study was to determine the seroprevalence of hepatitis C infection and associated risk factors among addicted prisoners in Sari-Iran. This is a simple random sampling cross sectional study that was performed on 312 addicted prisoner men at Khazarabad addicts' prison in Sari/Iran in September 2001. Their blood samples were examined through third generation enzyme immunoassay. Data were collected through questionnaires and interview. Associated risk factors were compared in 82 hepatitis C antibody positive addicts (the affected group) and 148 hepatitis C antibody negative addicts (the unaffected group). Out of 312 addicted prisoners, 96 were hepatitis C anti body positive. The seroprevalence of hepatitis C infection was found to be 30.8%. Major associated risk factors in the affected group were as follows: duration of addiction, duration of imprisonment (mean 48 months), route of drug administration, length of alcohol consumption, tattooing, shared usage of needles and razors, multiple sexual partners and type of drugs (p < 0.05). On multivariate logistic regression analysis these factors were found to be significant independent risk factors for HCV infection: tattooing (OR 100, 95% CI), multiple sexual partners (OR 4.97, 95% CI) and history of surgery (OR 6.23, 95% CI). It is concluded that hepatitis C infection had a considerable prevalence in addicted prisoners. High risk and unsafe behaviors were found to be the main factors of contamination.
