Abstract
Background Nurses, as the largest group of health professionals, are at the frontline of the healthcare system in response to COVID-19 epidemic. This study aimed to evaluate the nurses’ certainty and satisfaction with medical gloves when exposed to coronavirus in Fars province, south of Iran. Methods Using convenience sampling, 400 hospital nurses during the COVID-19 outbreak were selected from eight hospitals of Shiraz University of Medical Sciences (SUMS). A questionnaire about glove reliability, including protection in tasks, durability, integrity and tear resistance, feeling fearful, and focusing on duties, and the nurses’ anxiety regarding their infection with coronavirus was distributed to the selected nurses to complete. 375 questionnaires were completed (response rate of 93.75%). Among the participants, 180 (48%) were in the corona section and 195 (52%) were hardly possible to have contact with coronavirus pneumonia patients. Results The mean score (SD) of anxiety about infection with COVID-19 for nurses in the COVID-19 section and those in the non-COVID-19 section were 6.08 (2.8) and 4.56 (2.58), respectively (p < 0.05). The mean duration of gloves usage in a day was almost similar in the two groups (about 5 h), but the number of glove replacements was significantly higher among the nurses in the corona section (6 times) compared to those in the non-corona section (3 times). The two groups were also significantly different regarding glove protection in daily tasks and glove durability. Conclusion The nurses in the corona section had more concerns about medical gloves as a type of personal protective equipment. In addition to health education on controlling and preventing the spread of diseases, raising awareness about the reliability of personal protective equipment can improve nurses’ performance.

Abstract
Background: The most common sexually transmitted infection is infection by human papilloma virus (HPV). Although the main transmission route of HPV is through sexual intercourse, the contact of the skin with the genital area skin is another known method for transmission. This study aims to examine the awareness and practice of female beauty salon staff about HPV and its transmission in pubic hair removal using wax. Materials and Methods: This cross-sectional study was conducted on 200 female beauty salon staff who do bikini waxing in Shiraz, Iran. Demographic information, awareness, and practice of them were gathered using the researcher-constructed questionnaire. The statistical analysis was performed using the SPSS software version 18. Results: Mean awareness and practice scores of beauty salon staff about HPV and its transmission in bikini waxing were 26.6 ± 12.8 and 5.5 ± 0.8, respectively, and in average range. The results showed that there was a significant relationship between practice and education (P = 0.04), but the relationship between the awareness and education was not seen (P = 0.72). There was no statistically significant relationship between age and work experience with awareness and practice of staff (P > 0.05). Conclusion: The awareness and practice of beauty salon staff about HPV and its transmission in bikini waxing are moderate. Therefore, it seems that the implementation of continuous educational program by the Union of women’s beauty salons is necessary to increase and improve the awareness and practice of female beauty salon staff.

Abstract
According to historical records of transatlantic slavery, traders forcibly deported an estimated 12.5 million people from ports along the Atlantic coastline of Africa between the 16th and 19th centuries, with global impacts reaching to the present day, more than a century and a half after slavery's abolition. Such records have fueled a broad understanding of the forced migration from Africa to the Americas yet remain underexplored in concert with genetic data. Here, we analyzed genotype array data from 50,281 research participants, which-combined with historical shipping documents-illustrate that the current genetic landscape of the Americas is largely concordant with expectations derived from documentation of slave voyages. For instance, genetic connections between people in slave trading regions of Africa and disembarkation regions of the Americas generally mirror the proportion of individuals forcibly moved between those regions. While some discordances can be explained by additional records of deportations within the Americas, other discordances yield insights into variable survival rates and timing of arrival of enslaved people from specific regions of Africa. Furthermore, the greater contribution of African women to the gene pool compared to African men varies across the Americas, consistent with literature documenting regional differences in slavery practices. This investigation of the transatlantic slave trade, which is broad in scope in terms of both datasets and analyses, establishes genetic links between individuals in the Americas and populations across Atlantic Africa, yielding a more comprehensive understanding of the African roots of peoples of the Americas.

Abstract
Introduction and Aim: The current study aimed at evaluating the effect of willpower workshop on anxiety, depression, and the Granovsky excitement components among the students of Shiraz University of Medical Sciences in the academic year 2016--2017. Materials and Methods: Students (140) were selected by the simple random sampling method and allocated into two equal groups of intervention (willing) and control, each of 52 individuals. Data collection instruments were the Garnefski cognitive emotion regulation scale and the Beck depression and anxiety inventories. The data were collected twice, before intervention and after the intervention (9 months after the study completion and holding the workshops). The control subjects received no intervention but were interviewed every 3 months. Results: The results of the current study indicated no significant differences in demographic variables and pretest scores between the groups, which indicate the homogeneity of the groups. In other words, there were no significant differences between the groups regarding demographic characteristics before the intervention (P > 0.05). In addition, to compare the intervention and control groups, the Mann--Whitney U test was used and the results showed a significant difference in posttest results between the study groups (P < 0.05). Also, there was a significant difference between the pretest and posttest results of each group (P < 0.05). Conclusion: Results of the current study indicated that training the stress, coping and willpower strengthening skills, based on the Granovsky excitement components, could promote psychophysical health and reduce anxiety and stress among the studied students.

Abstract
Background and Aim: Cancer is the second cause of death after cardiovascular diseases in the world. Each year, more than 70,000 new cases of cancer and 30,000 deaths from cancer have been recorded in Iran. Cancer also reduces quality of life (QoL) by creating negative physical and mental symptoms. The purpose of this study was to investigate the relationship between mental health, spiritual well-being and QoL among cancer patients receiving chemotherapy. Method: About 208 adults suffering from cancer and receiving chemotherapy in Shiraz hospitals were entered in the study and they were asked to complete the Paloutzian and Ellison Spiritual Well-being Questionnaire, and Goranowski Mental Health, Quality of Life and Excitement Questionnaire. For data analysis, descriptive statistics including mean (standard deviation) and frequency (percentages) were used in table and chart format, moreover Spearman correlation tests were also used. Results: The results of the study revealed that there was a positive and significant correlation between mental health and QoL (P = 0.001) in cancer patients receiving chemotherapy. The results of the study revealed that there was a positive and significant correlation between spiritual well-being and mental health (P = 0.001) and QoL (P = 0.01) in cancer patients receiving chemotherapy, but there was a negative and significant Correlation between spiritual well-being and negative emotions (P = 0.47). On the other hand, there was a negative and significant correlation between mental health (P = 0.026) and QoL (P = 0.019) and negative emotions respectively. Conclusion: The results of this study showed that there was a positive and significant relationship between spiritual well-being, mental health, and QoL in cancer patients.

Abstract
Objectives Vaginal Candidiasis with an approximate prevalence of 30% is the second cause of vaginal infections. Antifungal azole is the first treatment for Vaginal Candidiasis; however, some side effects have been reported for this chemical medicine. Based on the antifungal activity of Inner Stratum of Quercus Brantii (Q. Brantii), the aim of our study was to compare the effects of vaginal douche of Q. Brantii extract and clotrimazole on vaginal candidiasis symptoms before and after the treatments, in women. Methods 89 non-pregnant women with positive KOH test which is capable of identifying the presence of hyphae and mycelium by adding KOH (10%), and a positive vaginal candidiasis culture were randomly divided into two experimental groups, using permuted block randomization method. One group received clotrimazole vaginal cream (1%) and the other group received vaginal douche of Q. Brantii extract. Groups were treated for 7 days and KOH tests and cultures were evaluated again. Data were analyzed via chi-square and independent t-test, using SPSS software. Results According to the results, there were no significant differences between experimental groups for demographic characteristics like age (p=0.403), BMI (p=0.911), educational levels (p=0.862) and contraceptive methods (p=0.702). Moreover, significant differences were seen in vaginal discharge between the groups after the treatments (P=0.043). Conclusion The results suggested that the therapeutic effect of vaginal douche of Q. Brantii extract was approximately similar to that of clotrimazole vaginal cream.

Abstract
New technologies, such as serious games and ambient activities, are being developed to address problems of under-stimulation, anxiety, and agitation in millions of people living with dementia in long term care homes. Frequent interactions with instrumented versions of these technologies may not only be beneficial for long term care residents, but may also provide a valuable new set of multifaceted data related to the health status of residents over time. In this paper, we develop a model for health monitoring in healthcare environments and we report on two studies that show how medically relevant data can be collected from elderly residents and emergency department patients in an unobtrusive way. The first study shows how data related to cognitive abilities can be collected from elderly emergency department patients and the second study shows how detailed data on a range of factors can be collected from ambient activity units designed to provide engaging interactions for long term care residents. In summary, this paper proposes the use of new technologies to transform long term care from a data poor to a data rich environment, where the health status of long term care residents and elderly patients is more closely monitored.

Abstract
Introduction: Hirsutism is a common disorder that has remarkable physical and mental effects on individuals. No appropriate diet has yet specified for individuals with hirsutism. The present study was carried out to examine the effect of high-fibre, low-caloric balanced diet on some related hormone levels in obese or overweight women with hirsutism who had referred to clinics affiliated with Shiraz University of Medical Sciences. Materials and Methods: The present study was a clinical trial that was carried out on 47 obese or overweight women with hirsutism in 2014. The women were randomly assigned to an intervention group and a control group that, respectively, consumed a high-fiber, low-caloric balanced diet and a normal diet for 3 months. A demographic characteristics questionnaire and a researcher-designed diet questionnaire were filled out by the two groups before the intervention. Before and 12 weeks after the intervention, body mass index (BMI) was measured and blood samples (on the 3–5 days of menstruation) were collected. Factors of luteinizing hormone, follice stimulating hormone, sex hormone binding globulin, dehydroepiandrosterone sulfate, low-density lipoproteins, high-density lipoproteins (HDL), fasting blood sugar (FBS), CHOL, prolactin, triglycerides, insulin, 17-hydroxyprogesterone, and free androstenedione testosterone were measured. The collected data were analyzed through t-test, Chi-square, and intergroup analysis using SPSS 22.0. Results: The mean age of the participating women was 27.23 ± 5.42 years. After the study, the level of FBS and insulin in the intervention group dropped while they increased in the control group. Moreover, the postintervention level of BMI in the intervention group on average decreased 1.89 units while it rose by 0.3 units in the control group, and there was a significant difference between the two groups (P < 0.001). Conclusion: The results of the present study showed that consuming high-fiber diet by obese or overweight women with hirsutism and polycystic ovary can reduce some factors including the level of FBS, insulin, and cholesterol and enhance blood HDL. Therefore, consuming this type of diet is recommended to treat this disorder.

Abstract
In this study, we have reported the synthesis of graphene oxide nanosheets (GON) and its functionalization with 2, 4, 6-trichloro-1, 3, 5-triazine (TCT) through two routes, (a) directly reaction of GON with TCT (GON-1), and (b) reaction of GON with pre-functionalized TCT with 3-aminopropyltriethoxysilane (APTS) (GON-2). Subsequently, GON, GON-1 and GON-2 have been used as supports for immobilization of Candida rugosa lipase (CRL). Several techniques such as XRD, SEM, EDS, UV-Vis, CHNS, FTIR and AFM were applied to characterize the nano-structures and success of synthesis, functionalization and CRL immobilization processes. The results corresponding to optimization of immobilization process revealed the following order for values of loading capacity, immobilization yield and leaching of CRL: GON > GON-1 > GON-2, while this order is reversed for, specific activity and recovery activity. The assessment of operational parameters represents the high storage stability and reasonable reusability for all the immobilized CRL while the pH and thermal stability of CRL@GON-2 are higher than two others. It seems the longer linker of GON-2 could more effectively prevent the unfavorable interaction between enzyme-enzyme and enzyme-product that consequently resulted the best catalytic performance, pH and thermal stability. The advantages of these supports make them suitable candidates for practical applications.

Abstract
Oxidative potential (OP) is related to the organic phase, specifically to its oxygenated organic fraction (OOA). Furthermore, the oxygen content of fuel molecules has significant influence on particulate OP. Thus, this study aimed to explore the actual dependency of the OOA and ROS to the oxygen content of the fuel. In order to reach the goal, different biodiesels blends, with various ranges of oxygen content; have been employed. The compact time of flight aerosol mass spectrometer (c-ToF AMS) enabled better identification of OOA. ROS monitored by using two assays: DTT and BPEA-nit. Despite emitting lower mass, both assays agreed that oxygen content of a biodiesel is directly correlated with its OOA, and highly related to its OP. Hence, the more oxygen included in the considered biodiesels, the higher the OP of PM emissions. This highlights the importance of taking oxygen content into account while assessing emissions from new fuel types, which is relevant from a health effects standpoint.

Abstract
Introduction. Secure airway for proper ventilation during anesthesia is one important component of a successful surgery. Endotracheal intubation is one of the most important methods in this context. Intubation method and used medication are considerably important in attenuating complications. This research aimed to investigate the impact of two different doses of dexmedetomidine in mitigating cardiovascular responses to endotracheal intubation in candidate cases supporting voluntary operation. Methods. The current research contained 90 cases in the range of 18 and 50 old, with ASA I,II supporting voluntary operation, who were randomly classified into three teams, each group consisting of 30 cases. The first set (A) got 0.5 μg/ kg dexmedetomidine, the second set (B) got 1 μg/ kg dexmedetomidine and the third set (C) got an equal volume of saline as placebo, 600 seconds earlier the initiation of anesthesia. Hemodynamic parameters were recorded at baseline (T0), then after the injection and the earlier initiation of anesthesia (T1), after the induction of anesthesia and before the endotracheal intubation (T2), promptly after tracheal intubation, 180, and 300 after endotracheal intubation (T4, T5). Data was analyzed and p < 0.05 was supposed notable. Findings. In this research, 3 teams were similar regarding weight, age, height, sex and duration of laryngoscopy. The diastolic mean arterial pressure, heart rate, and systolic arterial pressure were significantly lower in dexmedetomidine teams (A,B) at all times after the endotracheal intubation compared to group C. There were no significant differences in hemodynamic factors among group A, B. Conclusion. Dexmedetomidine effectively and significantly attenuates cardiovascular and hemodynamic responses during endotracheal intubation. In addition, different doses of dexmedetomidine did not cause any significant distinct result in mitigating cardiovascular responses.

Abstract
A quantiatative structure property relationship (QSPR) treatment was used to a data set consisting of diverse 3-hydroxypyridine-4-one derivatives to relate the logarithmic function of octanol:water partition coefficients (denoted by log po/w) with theoretical molecular descriptors. Evaluation of a test set of 6 compounds with the developed partial least squares (PLS) model revealed that this model is reliable with a good predictability. Since the QSPR study was performed on the basis of theoretical descriptors calculated completely from the molecular structures, the proposed model could potentially provide useful information about the activity of the studied compounds. Various tests and criteria such as leave-one-out cross validation, leave-many-out cross validation, and also criteria suggested by Tropsha were employed to examine the predictability and robustness of the developed model.

Abstract
BACKGROUND Allergic rhinitis is a complex polygenic disorder of the upper respiratory tract. Given that proinflammatory cytokines such as tumor necrosis factor (TNF) and interleukin (IL) 1 seem to play a role in the development of allergic rhinitis, we evaluated the associations between various single-nucleotide polymorphisms (SNPs) of the TNF and IL1 genes in a case-control study. METHODS The study population comprised 98 patients with allergic rhinitis. Genotyping was performed using polymerase chain reaction with sequence-specific primers for 2 TNFA promoter variants (rs1800629 and rs361525), 1 variant in the promoter region of IL1A (rs1800587), 2 SNPs in the IL1B gene (rs16944 and rs1 143634), 1 variant in the IL1 receptor (rs2234650), and 1 in IL1RA (rs315952). RESULTS Patients who were homozygous for the T allele of rs16944 in IL1B had an 8.1-fold greater risk of allergic rhinitis than those with the C allele. In TNFA, a significant relationship was also detected between rs1800629 and rs361525 and allergic rhinitis. Except for rs1800587 in IL1A and rs315952 in IL1RA, significant differences were found between the patient and control groups for all other SNPs. CONCLUSIONS We found that allelic variants in the TNFA and IL1 genes were not only associated with the risk of developing allergic rhinitis, but also affected disease course and severity.

Abstract
INTRODUCTION Ramadan, the holy month for the Islamic world, is a period every year when food and fluid intake is restricted to the pre-sunrise and post-sunset hours. The aim of this study was to evaluate the effect of Ramadan fasting on the serum concentration of heat shock protein 70 (HSP70) and serum lipid profile in healthy men. METHODS A total of 32 male volunteers with a mean age of 28.5 (range 23-37) years were selected for the study. Blood samples were obtained one day prior to Ramadan and on the 3rd and 25th days of fasting. Serum HSP70, triglyceride (TG), cholesterol (Chol), low-density lipoprotein (LDL) and high-density lipoprotein (HDL), LDL/HDL and Chol/HDL ratios were investigated. RESULTS It was observed that the mean concentrations of serum HSP70 and HDL on the 25th day of Ramadan were significantly higher than those recorded one day before Ramadan and on the 3rd day of Ramadan, and the levels on the 3rd day of Ramadan was significantly higher than those recorded one day before Ramadan. Mean concentrations of serum TG, Chol, LDL, and LDL/HDL and Chol/HDL ratios on the 25th day of Ramadan were significantly lower than those recorded one day before Ramadan and on the 3rd day of Ramadan, and the levels found on the 3rd day of Ramadan were also significantly lower than those recorded one day before Ramadan. CONCLUSION Ramadan fasting increases serum HSP70 and improves serum lipid profile.

Abstract
In this paper a closed-loop control algorithm for blood glucose regulation in type 1 diabetic patients is proposed by using the Mamdani-type fuzzy method. Because of the presence of high-pass proportional derivatives in fuzzy designing, optimal values are applied for two inputs and one output membership functions in order to prevent the fluctuations due to derivatives in fuzzy design. Therefore, 19 values which are related to membership functions of the two inputs and one output are obtained by using a genetic algorithm (GA). The new model, termed the Augmented Minimal Model (AMM), is used in simulations. This controller is capable of stabilizing the blood glucose concentration at a normoglycaemic level of 90 mg dl(-1). The operation of the controller under various situations including multiple meal disturbances, and noise due to inaccurate effects of measuring blood glucose level are considered. Uncertainties in the meal disturbance function and variations of model parameters were also taken into consideration in simulations and the controller was found to be robust to such uncertainties.

Abstract
We demonstrate that in a d-wave superconductor the bulk nonlinear Meissner effect is dominated by a surface effect due to Andreev bound states at low temperatures. The contribution of this surface effect to the nonlinear response coefficient follows a 1/T3 law with the opposite sign compared to the bulk 1/T behavior. The crossover from bulk dominated behavior to surface dominated behavior occurs at a temperature of T/Tc∼1/square root(κ). We present an approximate analytical calculation, which supports our numerical calculations and provides a qualitative understanding of the effect. The effect can be probed by intermodulation distortion experiments.

Abstract
BACKGROUND Common variable immunodeficiency (CVID) is the most common symptomatic antibody deficiency. It is characterized by hypogammaglobulinemia, increased susceptibility to recurrent infections, autoimmunity, and malignancies. OBJECTIVES To determine whether patients with CVID have cytokine production defects after T-cell activation and to assess whether or not these are correlated with markers of severe disease. METHODS Twenty-seven patients with CVID and 17 healthy volunteers were investigated. Peripheral blood mononuclear cells were cultured under standard conditions in the presence and absence of phytohemagglutinin. Subsequent cell proliferation and cytokine release were measured and compared between stimulated and unstimulated cells. RESULTS A general enhancement in cytokine production was observed in both CVID patients and controls after stimulation. However, we detected a lower production of interferon-gamma in CVID patients than in controls (P = .026). A production defect for at least 1 cytokine was observed in 12 patients. Ten of these failed to generate protective titers in response to the polysaccharide vaccine, and the frequency of bronchiectasis in this group of patients was 91.7%. Cytokine release correlated strongly with cell proliferation. CONCLUSIONS This study indicates that some CVID patients have T-cell proliferation and secretory defects and that these may be associated with severe manifestations of disease. Screening for such defects could permit more effective monitoring and therapeutic strategies for CVID patients.

Abstract
Objective To investigate whether daily diet provides adequate selenium intake in healthy men and women living in Tehran, Iran. Method Serum level of selenium was determined in 184 healthy individuals of both genders. The samples were divided into two age groups, adults and children, for analysis. The serum level of selenium was determined using hydride generation and flame atomic absorption spectroscopy. Results The mean and standard deviation of serum selenium levels in children (1–16 years) was 84.3 ± 11 μg/l and there was no significant difference between genders in this group. In adults (older than 16 years) the mean serum selenium level was 100.6 ± 13 SD μg/l; among women the mean was 93.9 ± 14 SD μg/l and among men it was 102.2 ± 12 SD μg/l. The mean selenium level in men was higher than in women and data analysis showed a significant difference between them (p < 0.005). There was also a positive correlation between higher selenium serum concentration and age in men (P < 0.001). Daily intake of selenium in men and women was calculated to be 67 μg and 62.1 μg respectively. Conclusion Our results show that the serum concentration of selenium in an Iranian population is similar to other nationalities in the Middle East, particularly Saudi Arabia.

Abstract
In order to standardize Nerve Conduction Velocity(NCV), proximal and distal latency and amplitude of motor conduction in intact accessory nerves, a cross-sectional, descriptive-analytic study was done on 60 healthy persons with strict attention to number of cases, distance between stimulation sites, temperature and age. The average results were as follows: Distal latency 2.54 milliseconds (msec.) (2.25-2.83), Proximal latency 3.64 msec. (3.34-3.94), Amplitude 13.76 millivolts (mv.) (8.56-18.96) and NCV 67.98 m/s (56.95-79.01). The average latencies in women were significantly less than men, on both sides which can be due to higher superficial skin temperature in women.
