Abstract
Introduction: Cardiovascular disease (CVD) accounts as a major cause of mortality among patients with nonalcoholic fatty liver disease (NAFLD). Resveratrol, a natural polyphenol compound, is known for its antioxidant and antiatherogenic properties and is purported to be beneficial in decreasing CVD risk factors in NAFLD patients. Objectives: This study aimed to investigate the effects of resveratrol on atherogenic risk factors in patients with NAFLD. Methods: This randomized, double-blind, placebo-controlled clinical trial was performed on 50 patients with NAFLD aged 20-60 years. Subjects were randomly assigned to receive a daily dose of 600 mg resveratrol (n = 25) or placebo (n = 25) for 12 wk. Serum liver enzymes, lipid profile and atherogenic indices, blood pressure and anthropometric values were assessed pre and post-treatment. Results: Resveratrol supplementation reduced body weight (from 88.75 ± 11.41 to 87.54 ± 11.18 kg, P = 0.005) and BMI (from 31.00 ± 3.16 to 30.60 ± 3.26 kg/m², P = 0.01) significantly compared to the placebo group. A significant reduction in waist circumference was observed within resveratrol group (from 102.70 ± 7.68 to 101.39 ± 7.62 cm, P = 0.02). There were no significant changes in lipid profile (ox-LDL, ApoA1 and ApoB), serum atherogenic indices (LDL-C/HDL-C, ApoB/ApoA1, ox-LDL/ApoB, LDL-C/ox-LDL and AIP), liver enzymes (AST, ALT, ALP and GGT), hip circumference, waist-to-hip ratio and blood pressure in either group (P > 0.05 for all). Conclusion: These findings indicated that resveratrol supplementation in dose and duration used in this study did not affect most of the CVD risk factors in NAFLD patients. Further studies are warranted to explain more effects of resveratrol on CVD complications of NAFLD. Registration ID in IRCT: IRCT201511233664N16.

Abstract
Background: There is an assumption that sexual health research has great influence on the quality of human life through elevating sexual health standards, and their results will eliminate the burden of sexual health challenges on family relationships. The aim of this study was to review ethical considerations in sexual health research. Materials and Methods: This narrative review was conducted between January 1990 and December 2017 based on the five-step approach of York University. The keywords used to search for the studies included ethical issues, research, sexual health, reproductive health, and sensitive topics. The language of the literatures was English and the search process was performed on PubMed, Elsevier, Ovid, Springer, Google Scholar, ResearchGate, SAGE Publishing, ProQuest, WHO website, Kinsey Confidential, and Worldsexology. Results: After assessing the quality and eligibility of 94 articles, 13 were selected. The results of the present study showed that the most important ethical considerations were protecting the confidentiality and privacy of participants, obtaining informed consent, and paying attention to vulnerable people. Conclusions: The review of literature exhibited several considerations that sexual health researchers are faced with. In order to manage these considerations, the researcher should have sufficient understanding of them. The important matter is that strategies to manage these challenges should be completely rational and practical according to each context. These strategies can also be applied in other societies with great similarities in their context.

Abstract
Abstract
Almonds can be classified based on their shell characteristics from soft to hard shell varieties. The majority of Australian and Californian varieties have soft shell properties. Most Spanish almond varieties have hard shells. Although having a hard sealed shell protects the kernel from insect damage it affects their processability. Common commercial almond processing equipment simultaneously compresses and shears the almonds and this creates a high percentage of damaged kernels from the broken shell being forced into the kernel, particularly for hard shell varieties. This paper shows that for the soft shell variety ‘Nonpareil’ and the three hard shell varieties of ‘Marcona’, ‘Tarraco’ and ‘Vyro’ that conditioning by soaking in water and resting before processing improves the recovery of undamaged kernel when shelling using impact. The impacts were applied by feeding the almonds into a rotating impellor and throwing them onto a stationary outer wall. An effective conditioning process resulted in the kernel moisture content increasing from 6% to 14% for hard shell and to 11% for ‘Nonpareil’ varieties. The conditioning process was measured to reduce the amount of scratched, chipped and broken kernel, and hence increased the recovery of undamaged kernel. After shelling, the conditioned kernel needed to be dried back to a 6% moisture content to be suitable for storage. Hence, the industry would be able to increase its recovery of undamaged kernel by changing to an impact shelling process using suitably conditioned almonds.

Abstract
Abstract
Finite element (FE) models of uniaxial loading of pumpkin peel and flesh tissues were developed and validated using experimental results. The tensile model was developed for both linear elastic and plastic material models, the compression model was developed only with the plastic material model. The outcomes of force versus time curves obtained from FE models followed similar pattern to the experimental curves; however the curve resulted with linear elastic material properties had a higher difference with the experimental curves. The values of predicted forces were determined and compared with the experimental curve. An error indicator was introduced and computed for each case and compared. Additionally, Root Mean Square Error (RMSE) values were also calculated for each model and compared. The results of modeling were used to develop material model for peel and flesh tissues in FE modeling of mechanical peeling of tough skin vegetables. The results presented in this paper are a part of a study on mechanical properties of agricultural tissues focusing on mechanical peeling methods using mathematical, experimental and computational modeling.

Abstract
Objective Bone marrow and umbilical cord stromal cells are multipotential stem cells
that have the ability to produce growth factors that play an important role in survival and
generation of axons. The goal of this study was to evaluate the effects of the two different
mesenchymal stem cells on peripheral nerve regeneration.
Materials and Methods In this experimental study, a 10 mm segment of the left sciatic
nerve of male Wistar rats (250-300 g) was removed with a silicone tube interposed into
this nerve gap. Bone marrow stromal cells (BMSCs) and human umbilical cord stromal
cells (HUCSCs) were respectively obtained from rat and human. The cells were sepa-
rately cultured and transplanted into the nerve gap. The sciatic nerve regeneration was
evaluated by immunohistochemistry, and light and electron microscopy. Moreover, histo-
morphology of the gastrocnemius muscle was observed.
Results The nerve regeneration in the BMSCs and HUCSCs groups that had received
the stem cells was significantly more favorable than the control group. In addition, the BM-
SCs group was significantly more favorable than the HUCSCs group (P<0.05).
Conclusion The results of this study suggest that both homograft BMSCs and het-
erograft HUCSCs may have the potential to regenerate peripheral nerve injury and
transplantation of BMSCs may be more effective than HUCSCs in rat.

Abstract
Enhancing quality of food products and reducing volume of waste during mechanical operations of food industry requires a comprehensive knowledge of material response under loadings. While research has focused on mechanical response of food material, the volume of waste after harvesting and during processing stages is still considerably high in both developing and developed countries. This research aims to develop and evaluate a constitutive model of mechanical response of tough skinned vegetables under postharvest and processing operations. The model focuses on both tensile and compressive properties of pumpkin flesh and peel tissues where the behaviours of these tissues vary depending on various factors such as rheological response and cellular structure. Both elastic and plastic response of tissue were considered in the modelling process and finite elasticity combined with pseudo elasticity theory was applied to generate the model. The outcomes were then validated using the published results of experimental work on pumpkin flesh and peel under uniaxial tensile and compression. The constitutive coefficients for peel under tensile test was α = 25.66 and β = -18.48 Mpa and for flesh α = -5.29 and β = 5.27 Mpa. under compression the constitutive coefficients were α = 4.74 and β = -1.71 Mpa for peel and α = 0.76 and β = -1.86 Mpa for flesh samples. Constitutive curves predicted the values of force precisely and close to the experimental values. The curves were fit for whole stress versus strain curve as well as a section of curve up to bio yield point. The modelling outputs had presented good agreement with the empirical values and the constructive curves exhibited a very similar pattern to the experimental curves. The presented constitutive model can be applied next to other agricultural materials under loading in future.

Abstract
Premenstrual syndrome (PMS) is a distressing group of symptoms related to menstrual cycle during reproductive age. Its substantial burden on daily function and quality of life, particularly on mental aspects, was to the impetus for this study with the aim of determining the effectiveness of a psycho-educational package on premenstrual syndrome and related symptoms. In a randomized clinical trial, 123 (17-19-year-old) adolescent girls with PMS were randomized to psycho-educational intervention (including 62 subjects) and control (including 61) groups. The participants completed a demographic questionnaire, premenstrual syndrome symptom daily record scale and the Symptom Checklist-90-Revised (SCL-90-R). A paired and two independent samples t-test and chi-squared test were used for analysing data using SPSS statistical package. At the end of the study there was statistically significant decrease in severity of total PMS in intervention compared with control group (P < 0.001). Also, a significant difference in somatization, anxiety and hostility was observed between two groups (P < 0.05). However, depression marginally decreased (P < 0.1) in intervention group, and interpersonal sensitivity was not statistically different between intervention and control groups. Intervention alleviated the severity of PMS and related somatization, anxiety and hostility, yet it could not change the severity of depression and interpersonal sensitivity.

Abstract
OBJECTIVE Premenstrual syndrome is a common disorder experienced by up to 50% of women during reproductive age. The prevalence of severe form of PMS (PMDD) is 3% to 8 %. Psychiatric disorders in PMS patients have resulted in significant morbidity and in some cases caused resistance to the treatment process. MATERIAL AND METHOD 390 participants (264 with PMS/PMDD, and 126 healthy students of University of Guilan) who completed the demographic questionnaire, daily symptom rating (DSR) and the checklist 90-revised (SCL-90-R) took part in this study. This study was conducted using a cross sectional method. RESULTS According to repeated measure variance, the mean scores of psychiatric symptoms (Depression, Anxiety, Aggression, Interpersonal sensitivity) in the PMS group were significantly higher than the healthy group (p< 0/05), and increase in severity of PMS from mild to severe was accompanied by increase in mean score of these subscales. There was a significant difference in mean score of depression, anxiety, aggression and interpersonal sensitivity between the 3rd and the 13th day of the cycle. Significant effect of the DSR grouping (PMS and Healthy group) and time interaction emerged in interpersonal sensitivity and aggression, significant effect on the DSR grouping (Mild, Moderate, Severer) and time interaction demonstrated in interpersonal sensitivity. CONCLUSION Patients with prospective confirmed PMDD seemed to suffer from psychiatric symptoms. Therefore, recognizing co-morbid psychiatric symptoms in patients with PMDD is of prime importance. All healthcare providers should be sensitive to mental status of women with PMS.

Abstract
OBJECTIVE Cardiac diseases are psycho-somatic disorders, and psychological aspects play an essential role in their initiation and exacerbation. The aim of this study was to gain appropriate knowledge in the epidemiology of co-morbid depression and anxiety disorder in cardiovascular outpatients. METHOD This study is descriptive with a sample of patients attending a cardio-vascular clinic. 238 individuals were included in this study using a consecutive sampling method. The study instrument was Hospital Anxiety and Depression Scale (HADS) questionnaire, which is a clinical scale for assessing anxiety and depression. RESULTS Of the 238 participants in this study, 93(38.7%) were male and 146 (61.3%) female. 28.5% of patients suffered from anxiety disorders, and 41.9% had depression. Regarding comorbid diseases such as diabetes mellitus, hyperlipidemia and hypertension, the severity of depression was just related to hypertension. There was a meaningful relationship between gender and symptoms of anxiety so that symptoms were more severe in women. CONCLUSION Considering the high prevalence of depression and anxiety in patients suffering from cardio-vascular diseases, it is necessary to screen psychological disorders in patients with cardio-vascular diseases and improve their cardio-vascular health and quality of life as mush as possible.
