Abstract
Introduction: Serological assay has critical role in defining immunity based on seroprevalence. Identifying the extend of seropositivity would determine the truly infected cases. Method: We conducted serologic testing for SARS-COV-2 antibodies in 492 health care workers (HCWs) before vaccination program in Shiraz, Iran (30 April 2020). Results: Based on job position, cases were divided into two categories: frontline staff (169, 34.34%) and non-front-line staff (323, 65.65%). Of all cases 40.65 were female and the rest of them were male. Mean age was estimated 47.97 ± 109.20 and 38.98 ± 8.76 in high risk and low risk population respectively (P = 0.1). In total 367 (74.59%) subjects reported to suffered at least one of the COVID-19 symptoms. More than half of cases (73.57) had history of COVID-19 disease within six months before this survey. No relation was seen between blood type and immunoglobulin positivity. Seropositivity prevalence in low risk and high-risk populations were estimated 8.0 (95% CI: 1.0-16.8) and 5.2(95% CI: 1.2-9.8) respectively. The immunoglobulin test for SARS-COV-2 revealed that 64 (64/492, 13%) and 37 (37/492, 7.52%) subjects had IgG and IgM antibodies against the virus. 14 (14/169, 8.28%) individuals who had IgM were frontline health workers, this is while 23 (14/323, 7.12%) were non front lineConclusion: The findings of this study imply that seropositivity was lower in non-frontline health care staff. Furthermore, there was no association between blood type and seropositivity. Therefore, the knowledge of antibody status may help into overcome fears in clinical staff, and also more attention is need for interpreting the levels of anti-SARS-CoV-2 antibodies to make a clinical diagnosis of COVID-19, since the time of expose and time of test is an important point which should be considered in the issue.

Abstract
The mist bioreactor has been proved to have a higher performance relative to the liquid phase reactor. The water and conventional media (MS, ½MS, and B5) were tested in a mist bioreactor to evaluate the performance of the misting system. The physicochemical properties of liquids were measured at 0 (Fresh state) and when treated by ultrasonic system for 1 and 2 h. At a given airflow rate, the misting rate for different heights of various media was determined. The results demonstrated that the electrical conductivity of all media increased with the duration of sonication. The ultrasonic effect caused an increase in surface tension of MS and ½MS, while the pH of MS and ½MS reduced with ultrasonic treatment. The inverse trends were observed for water and B5 for these properties. The misting rate increased by increasing liquid height to a maximum value, then decreased to a minimum value at the highest height. For all liquids studied in this experiment, this maximum value of misting performed at height ranged between 3 and 4 cm. The maximum and minimum values of the ultrasonic misting rate belonged to MS ([Formula: see text]) at height 3 cm and B5 ([Formula: see text]) at height 1 cm, respectively.

Abstract
Nowadays, artificial intelligence techniques have become widely used in electrical machines optimization and design. In this attempt, different methods have been proposed. The present work is devoted to the electromagnetic analysis and design of an in-wheel radial flux outer rotor surface mounted permanent magnet motor (SMPM) for electric vehicle application. Two based-Swarm Particle Optimization (PSO) techniques, namely, the improved PSO multi-Objective optimization and the Speed-constrained Multi-objective PSO Optimization, are applied. The main idea of the current optimization procedure is to determine the optimal machine sizing parameters providing the maximum of efficiency with the minimum of weight. To reach this goal, two objective functions are employed the efficiency maximization and the weight minimization. A preliminary analytical model describing the magnetic and electrical machine features was presented. In order to find the optimum design, the optimization results are discussed and analyzed. In addition, the electromagnetic performances of the found optimum design were studied by means of finite element analysis (FEA) and compared with those obtained by the optimization procedure.

Abstract
Calcium Hydroxide (CH) is commonly employed as intracanal medicament in endodontics. In order to maximize its therapeutic effects, it is essential to develop new approaches for preparing the controlled drug release systems which, in turn, facilities the dissociation of CH into calcium and hydroxyl ions. This work studies the sustained-controlled release of calcium ions and the effect of pH changes on the different formulation of CH with hydrophilic natural polymers over a period of 30 days. Various formulations were prepared by combining CH with gelatin, aloe vera and gum tragacanth. Root canals of 60 human teeth were instrumented and filled with a different formulation of CH and suspended in plastic tubes containing distilled water. Three formulas of polymer/CH were evaluated, and pure CH powder was used as a control. At specific time intervals, the calcium ions release and the pH changes of the medium in different formulations were analyzed. The main interactions between the studied polymers and CH were investigated using FTIR spectra. The antibacterial activity of formulations against Enterococcus faecalis was also studied. Faster release of CH was observed for aloe vera/CH. Gum tragacanth/CH showed a slow-release during the first 15 days. In contrast, only Gelatin/CH formulation showed a prolonged release with statistically significant differences (P < 0.05). The pure CH showed significantly higher pH values than the other formulations. The Gelatin/CH formulation was a better sustained-release system than the pure CH, and it can be used as a promising vehicle for CH in the root canal treatment.

Abstract
OBJECTIVE To assess the relation between the ureteral length and the patients' size. PATIENTS AND METHOD Prospective study made between September 2012 and May 2014, on 87 patients with 42 men and 45 women, in whom the ureteral measure was performed during the various procedures that require the use of a pigtail stent. The average age of the population was 53 years old (±15.9) with an average height of 168.3cm (±8.4). This has been achieved through ureteral catheter combining fluoroscopy and endoscopy. RESULTS The ureteral average length was 23.5cm (±2.33). The ureteral average length was 23.8cm (±2.18) for man and 23.2cm (±2.44) for women. In this population, there were a positive correlation between the size of the patients and the length of the ureters (r=0.75; P=0.01). However, this correlation was not found in all subgroups, particularly among women (r=0.16; P=0.30) and on the right side of men (r=0.34; P=0.12). This correlation was still true for the left side in the men's group (r=0.50; P=0.02). CONCLUSION In this study, there is a positive correlation between the patients' size and the ureteral length. But this correlation is not found in some subgroups. It is better to perform in vivo the ureteral measurement to have the precise length in order to set up a pigtail stent adapted to the patient.

Abstract
SummaryFibrinogen plays an integral part in ADP-induced platelet aggregation. Controversy exists in regard to the role of the carboxy termini of fibrinogen Aa chains in this reaction. We have attempted to clarify this problem in view of the availability of a highly purified FII fibrinogen fraction. Kabi fibrinogen or its purified fractions FI, FII and FIII-IV-V were added to washed platelets in the presence of Tyrode-HEPES buffer pH 7.4. Aggregation was initiated by the addition of calcium and ADP. These fibrinogen fractions equally promoted ADP-induced platelet aggregation. The major difference among these fractions is in their Aα chains. The FI fraction contains intact Aα chains while FII and FIH-IV-V fractions have one and two partially degraded Aα chains at the carboxy terminal portion respectively. We conclude that the carboxy terminal portion of the Aα chain does not play an important role in promoting ADP-induced platelet aggregation.

Abstract
SummaryPlatelet aggregation with epinephrine, adenosine diphosphate and arachidonic acid was studied in the presence of cigarette smoke and carbon monoxide. It is shown that cigarette smoke inhibits the arachidonic acid induced platelet aggregation as well as the second phase of epinephrine induced aggregation. The adenosine diphosphate induced platelet aggregation is not significantly affected by cigarette smoke. Carbon monoxide causes similar alterations in platelet aggregation. These results suggest that cigarette smoke inhibits platelet aggregation. This aggregation inhibition is due to the presence of carbon monoxide.

Abstract
In the study of the expression of CatSper genes, consideration of the effects of environmental metal toxicity is very important. Therefore, in this study, the effects of lead acetate and mercury chloride exposure on expression of CatSper genes, sperm parameters, histology of testis and prooxidant antioxidant balance (PAB) values of serum were investigated. A total of 28 mice was divided into four groups. The control group did not receive injections. The sham group received normal saline intraperitoneally. Lead and mercury groups were injected 60 and 1.25 mg/kg/daily lead acetate and mercury chloride respectively intraperitoneally for 2 weeks. After 35 days, the sperm analysis and histology of left testis were performed. In addition, serum was obtained to measure the PAB values. The right testis was used for molecular analysis of real-time PCR. Administration with either lead acetate or mercury caused significant damage to the seminiferous tubules as well as a reduction in sperm parameters compared to the control group. The relative expression of CatSper 1 and CatSper 2 in the lead group was lower than that of the control group (-0.01 ± 0.24, -0.007 ± 0.52 vs. 1 ± 0.50, P = 0.34). The relative expression of CatSper 1 and CatSper 2 was significantly lower in the mercury group compared to the control ones (-0.24 ± 2.28, -4.49 ± 4.86 vs. 1 ± 0.50, P = 0.21). PAB values significantly increased in lead or mercury exposed- mice compared to the control ones (0.93 ± 0.17, 1.54 ± 0.17 vs. 0.51 ± 0.11; P ≤ 0.000). The results of this study showed that administration with either lead acetate or mercury chloride caused degenerative damage in seminiferous tubules and reduction in sperm quality and expression of CatSper 1, 2 genes in mice. Therefore, it is possible in infertile men who have had exposure to lead acetate or mercury chloride. Owing to structural similarities, these metals are substitutes for calcium ions and have effects on calcium channels. These cause immobility in sperm by blocking CatSper-specific calcium channels. However, more studies are required to elucidate the mechanism underlying the impact of different doses of heavy metals on CatSper genes expression.

Abstract
Direct partial oxidation of methane into methanol is a cornerstone of catalysis. The stepped conversion of methane into methanol currently involves activation at high temperature and reaction with methane at decreased temperature, which limits applicability of the technique. The first implementation of copper-containing zeolites in the production of methanol directly from methane is reported, using molecular oxygen under isothermal conditions at 200 °C. Copper-exchanged zeolite is activated with oxygen, reacts with methane, and is subsequently extracted with steam in a repeated cyclic process. Methanol yield increases with methane pressure, enabling reactivity with less reactive oxidized copper species. It is possible to produce methanol over catalysts that were inactive in prior state of the art systems. Characterization of the activated catalyst at low temperature revealed that the active sites are small clusters of copper, and not necessarily di- or tricopper sites, indicating that catalysts can be designed with greater flexibility than formerly proposed.

Abstract
Background: Uterine fibroma was a general gynecologic condition. When pharmacological therapies fail, surgical interferences such as myomectomy, hysterectomy, or embolization of uterine artery (UAE) are used as that state. This study aimed to compare hormone of anti-Mullerian measure among two methods of UAE, myomectomy into the treatment of uterine fibroma. Material and Method: In this clinical trial held in Imam Reza Hospital of Kermanshah, 40 cases by uterine fibroma were entered into the group of UAE (20 cases) and myomectomy (20 cases). Anti-Mullerian hormone levels were measured twice (ago and later therapeutic interventions) using the Monobinal kit. The information are examined by the SPSS (ver. 20.0) software by applying the Leven's test, paired and independent t-test, Wilcoxon, and Mann-Whitney tests. Results: There is n't matter variation in terms of age between two groups (P> 0.05). Not important variation is recognized regarding anti-Mullerian hormone level before and after six months the medical intervention in either group (P> 0.05). Also, no important variation was detected among the 2 groups in terms of the anti-Mullerian hormone level (P= 0.58). Conclusion: The results obtained demonstrated that where is not statistically important variation among UAE and myomectomy by in terms of anti-Mullerian hormone, which reflects ovarian capacity. Therefore, UAE, which is a less invasive method, can be a suitable substitute for surgical methods in the therapy of significant uterine fibroids between women of the sexual period.

Abstract
The central nervous system (CNS) constantly monitors nutrient availability in the body and, in particular, in the gastrointestinal (GI) tract to regulate nutrient and energy homeostasis. Extrinsic parasympathetic and sympathetic nerves are crucial for CNS nutrient sensing in the GI tract. These extrinsic afferent nerves detect the nature and amount of nutrients present in the GI tract and relay the information to the brain, which controls energy intake and expenditure accordingly. Dietary fat and fatty acids are sensed through various direct and indirect mechanisms. These sensing processes involve the binding of fatty acids to specific G protein-coupled receptors expressed either on the afferent nerve fibres or on the surface of enteroendocrine cells that release gut peptides, which themselves can modulate afferent nerve activity through their cognate receptors or have endocrine effects directly on the brain. Further dietary fat sensing mechanisms that are related to enterocyte fat handling and metabolism involve the release of several possible chemical mediators such as fatty acid ethanolamides or apolipoprotein A-IV. We here present evidence for yet another mechanism that may be based on ketone bodies resulting from enterocyte oxidation of dietary fat-derived fatty acids. The presently available evidence suggests that sympathetic rather than vagal afferents are involved, but further experiments are necessary to critically examine this concept.

Abstract
Chronic exposure to a diet rich in fats changes the gastrointestinal milieu and alters responses to several signals involved in the control of food intake. Oleoylethanolamide (OEA) is a gut-derived satiety signal released from enterocytes upon the ingestion of dietary fats. The anorexigenic effect of OEA, which requires intestinal PPAR-alpha receptors and is supposedly mediated by vagal afferents, is associated with the induction of c-fos in several brain areas involved in the control of food intake, such as the nucleus of the solitary tract (NST) and the hypothalamic paraventricular (PVN) and supraoptic nuclei (SON). In the present study we investigated whether the exposure to a high fat diet (HFD) alters the hindbrain and hypothalamic responses to OEA. To this purpose we evaluated the effects of OEA at a dose that reliably inhibits eating (10mg/kg i.p.) on the induction of c-fos in the NST, area postrema (AP), PVN and SON in rats maintained either on standard chow or a HFD. We performed a detailed analysis of the different NST subnuclei activated by i.p. OEA and found that peripheral OEA strongly activates c-fos expression in the AP, NST and in the hypothalamus of both chow and HFD fed rats. The extent of c-fos expression was, however, markedly different between the two groups of rats, with a weaker activation of selected NST subnuclei and stronger activation of the PVN in HFD-fed than in chow-fed rats. HFD-fed rats were also more sensitive to the immediate hypophagic action of OEA than chow-fed rats. These effects may be due to a decreased sensitivity of vagal afferent fibers that might mediate OEA's actions on the brain and/or an altered sensitivity of brain structures to OEA.

Abstract
A model diesel fuel containing 250 ppmw sulfur (as dibenzothiophene) in n-hexadecane was desulfurized at low temperatures in absence of hydrogen, down to about zero ppmwS on a novel adsorbent of well dispersed 3-12 nm Nix-Cu10-x (x=Ni wt%) nanoparticles formed by impregnation on γ-Al2O3 and reduced in H2 at 275 or 450°C. The sorbents were characterized by XRD, TEM-EDX, FESEM-EDS, H2-TPR, TPO, BJH and BET surface area measurement techniques. Effects of various parameters comprising Cu content, reduction and desulfurization temperatures, inhibition by naphthalene, and regeneration of spent sorbents were investigated. As copper is added to nickel: (a) the sorbent reduction temperature shifts to dramatically lower values, (b) sulfur adsorption capacity of the sorbents at lower reduction and desulfurization temperatures is significantly improved, and when 14 wt% Ni5Cu5 sorbent is added to the fuel, the sulfur content reduces from 250 ppmwS to about zero in less than 1 min, (c) loss of adsorption capacity after the regeneration of the spent sorbent reduced at 275°C is significantly diminished, and (d) the selectivity of the sorbents to dibenzothiophene in the presence of naphthalene is improved. A higher reduction temperature tends to agglomerate nickel nanoparticles and reduce the sulfur adsorption capacity.

Abstract
Imam Khomeini Port (IKP) is the largest Iranian commercial port. Because of many petrochemical industries and urban areas are located around this port and also having heavy ship traffic, concentrations of PAHs, mercury and other heavy metals were measured as the first time in surface sediment of the jetties. The highest concentrations of PAHs, Hg, Cu, Pb and Fe were recorded at Site 1, located in the vicinity of the petrochemical industrial zone, where ships are repaired. The highest concentration of Zn was found at Site 4, which is the jetty for loading mineral materials. The comparison between measured values in this study and some sediment quality guidelines indicated that the concentrations of mercury and PAHs are much higher than other studies. Also, the ratios of PAHs in the stations showed a mixture of both of pyrolytic and petrogenic sources with a dominance of pyrolytic sources.

Abstract
The purpose of this study was to determine the concentrations of metals, cadmium, chromium, lead and nickel in Liza vaigiensis and Johnius carutta, in order to: compare metal concentrations between two species with different gender, and to determine the significance between metal concentrations in the gill, liver and muscle. The highest mean concentrations of cadmium, chromium, lead and nickel in different tissues of these two fish species were found in the liver of L. vaigiensis at 0.68, 0.83, 0.37 and 1.42 μg g(-1), respectively; while the lowest mean concentrations of cadmium, chromium, lead and nickel were observed in the muscle of J. carutta at 0.16, 0.16, 0.03 and 0.29 μg g(-1), respectively. The results showed that the metal concentrations in both species were higher in the females than in the males (except chromium in gill and cadmium in muscle of J. carutta). Also, the results indicated that the metal concentrations were different among fish tissues (one-way ANOVA, p < 0.001), but there was no difference (except lead in gills of J. carutta) between sex (male vs. female).

Abstract
BACKGROUND Based on WHO reports, smoking is an epidemic in developing countries. One of important issues about this behavior is its distribution pattern in family members. The main purpose of this study was to evaluate if cigarette smoking had a tendency to cluster or aggregate in the families and what the determinants were. METHODS Using a multi-stage random cluster sampling approach, a household survey was conducted in Kish Island in 2009. We used the Alternating Logistic Regressions algorithm to model to show the familial aggregation. RESULTS The odds ratio for the aggregation of cigarette smoking between family members was 1.63 (1.29-2.06) which increased to 1.96 (1.50-2.55) after adjustment for demographic factors. There was no significant correlation between siblings' cigarette smoking nor was between spouses but the pairwise odds ratio for parents offspring was significant. In other words, cigarette smoking in at least one of the parents increased the odds of being a smoker in offspring significantly. CONCLUSION The study showed that the smoking behavior aggregated in families significantly. The inter-parent offspring aggregation was the main component of the familial aggregation. Higher education and age-gender interaction were determinants of smoking in the families. The programs for prevention and cessation of this behavior in the community might be more successful if they were designed in a family-based rather than an individual-based approach.

Abstract
The aim of this study was to examine the effectiveness of group reminiscence therapy on depression symptoms among elderly people attending a day centre in Shiraz, Islamic Republic of Iran. A sample of 49 people aged 60+ years participated in 6 group reminiscence sessions that were held twice weekly for a 3-week period and completed a Farsi version of the 15-item geriatric depression scale. Mean depression scores decreased significantly from 8.18 (SD 1.20) before the intervention to 6.73 (SD 1.20) immediately after it and 7.55 (SD 1.19) 1 month after the intervention. When analysed by demographic characteristics only marital status showed a statistically significant difference in depression scores comparing before and after the intervention.
