Abstract
This study evaluated the potential effects of long-term land use and climate change on the quality of surface runoff and the health risks associated with it. The land use change projection 2030 was derived from the main changes in land use from 2009 to 2019, and rainfall data was obtained from the Long Ashton Research Station Weather Generator (LARS-WG) model. The Long-Term Hydrological Impact Assessment (L-THIA) model was then utilized to calculate the rate of runoff heavy metal (HM) pollutant loading from the urban catchment. It was found that areas with heavy development posed a significantly greater public health risk associated with runoff, with higher risks observed in high-development and traffic areas compared to industrial, residential, and commercial areas. Additionally, exposure to Lead (Pb), Mercury (Hg), and Arsenic (As) was found to contribute significantly to overall non-carcinogenic health risks for possible consumers of runoff. Carcinogenic risk values of As, Cadmium (Cd), and Pb were also observed to increase, particularly in high-development and traffic areas, by 2030. This investigation offers important insight into the health risks posed by metals present in surface runoff in urban catchment areas under different land use and climate change scenarios.

Abstract
Line waves (LWs) refer to confined edge modes that propagate along the interface of dual electromagnetic metasurfaces while maintaining mirror reflection symmetries. Previous research has both theoretically and experimentally investigated these waves, revealing their presence in the microwave and terahertz frequency ranges. In addition, a comprehensive exploration has been conducted on the implementation of non-Hermitian LWs by establishing the parity-time symmetry. This study introduces a cutting-edge dual-band line-wave waveguide, enabling the realization of LWs within the terahertz and infrared spectrums. Our work is centered around analyzing the functionalities of existing applications of LWs within a specific field. In addition, a novel non-Hermitian platform is proposed. We address feasible practical implementations of non-Hermitian LWs by placing a graphene-based metasurface on an epsilon-near-zero material. This study delves into the advantages of the proposed framework compared to previously examined structures, involving both analytical and numerical examinations of how these waves propagate and the underlying physical mechanisms.

Abstract
This paper addresses the problem of designing a safe and optimal control strategy for typical cancer using the Control Barrier Function (CBF) technique. Cancer is a complex and highly dynamic disease characterized by uncontrolled cell growth and proliferation. By formulating the cancer dynamics as a control system, this study introduces a CBF-based controller that guides the cancerous tissue towards safe and controlled behaviors. The controller is designed to simultaneously optimize treatment efficacy and patient safety. The methodology involves modeling the cancer growth dynamics, incorporating relevant biological constraints, and designing the CBF-based controller to regulate the tumor's evolution within acceptable bounds. Simulation results demonstrate the effectiveness of the CBF-based strategy in achieving safe and optimal cancer control. The controller showcases the ability to drive the cancerous tissue towards desired states while respecting predefined safety constraints.

Abstract
Early diagnosis and prognosis are prerequisites for mitigating mortality in gastric cancer (GaCa). Identifying some causative or sensitive elements (coding RNA (cRNA)-non-cRNAs (ncRNAs)) can be very helpful in the early diagnosis of GaCa. Notably, despite significant development in the GaCa treatment, the outcome of patients does not remain satisfactory due to limitations such as multi-drug resistance and tumor relapse. Therefore, more attention has been drawn to complementary therapies and the use of supplements. In this regard, Polyphenol natural compounds (PNC) and maggot larvae (MaLa) alone or in combination were administered along with chemotherapy (paclitaxel) to N-methyl-N-nitrosourea (MNU)- induced murine tumor model. In addition, in order to identify potential diagnostic or prognostic biomarkers, transcriptomics analysis was performed through a bioinformatics approach. Then transcription profile of ncRNAs with their target hub genes was assessed through qPCR Real-Time, Western blot, and ELISA. According to the bioinformatics results, 17 hub genes (e.g., IL-6, CXCL8, MKI67, IL-2, IL-4, IL-10, IL-1β, SPP1, LOX, COL1A1, and IFN-γ) were explored that contribute towards inflammation and oxidative stress and ultimately GaCa development. Upstream of the mentioned hub genes, regulatory factors (lncRNA XIST and NEAT1) were also identified and introduced as prognosis and diagnosis biomarkers for GaCa. Our results showed that PNC alone and in combination with MaLa was able to reduce the size and number of tumors, which is related to the reduction of genes expression levels (including IL-6, CXCL8, MKI67, IL-2, IL-4, IL-10, IL-1β, SPP1, LOX, COL1A1, IFN-γ, NEAT1, and XIST). In conclusion, PNC and MaLa have the potential to be considered as complementary and improving chemotherapy due to their effective compounds. Also, the introduced hub gene and lncRNA in addition to diagnostic and prognostic biomarkers can be used as druggable proteins for novel therapeutic targeting of GaCa.

Abstract
The prevalence of cancer, especially in industrial countries, is a major problem for health and treatment systems. Cancer can affect the quality of life of all family members and has many negative effects on the community. Despite many advances in cancer treatment, this disease is still a major worldwide problem. There is strong evidence that dietary habits are effective in protecting against cancer and even helping in the disease treatment progress. Nuts with various biologically-active compounds, such as vitamins, phytosterols, isoflavones, flavonoids, and polyphenols have been reported to possess anticarcinogenic properties. Accordingly, this review provides an insight into the association between nut consumption and the prevention of some cancers. We considered the cancers related to the urogenital and genital tract, gastrointestinal tract, as well as women-related cancers. Both cell culture examinations and experimental animal studies alongside observational epidemiological studies demonstrated that regular consumption of a nut-enriched diet is able to reduce the risk of these cancers.

Abstract
INTRODUCTION The rapid emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants and their potential to endangering the global health has increased the demand for a fast-tracking method in comparison to the next-generation sequencing (NGS) as a gold standard assay, particularly in developing countries. This study was designed to evaluate the performance of a commercial multiplex real-time PCR technique (GA SARS-CoV-2 OneStep RT-PCR Kit, Iran) for identification of SARS-CoV-2 variants of concern (VOCs) compared to the Oxford Nanopore NGS assay. METHODS A total of 238 SARS-CoV-2-positive respiratory samples from different waves of COVID-19 in Iran were randomly selected in this study. To determine the SARS-CoV-2 VOC, the samples were analyzed via the commercial triple target assay, GA SARS-CoV-2 OneStep RT-PCR Kit, and NGS as well. RESULTS The results revealed good concordance between GA SARS-CoV-2 OneStep RT-PCR Kit and NGS for identification of SARS-CoV-2 VOCs. GA SARS-CoV-2 OneStep RT-PCR Kit identified Wuhan, Alpha, and Delta variants with 100% relative sensitivity and specificity. Regarding Omicron subvariants of BA.1, BA.2, and BA.4/5, the relative sensitivity of 100%, 100%, and 81.5% and the relative specificity of 95.3%, 93.5%, and 100% were observed. CONCLUSION Overall, GA SARS-CoV-2 OneStep RT-PCR Kit can be used as a rapid and cost-effective alternative to NGS for identification of SARS-CoV-2 VOCs.

Abstract
BACKGROUND Post-traumatic elbow stiffness (PTES) may substantially affect the patient's functional range of motion and quality of life. Open elbow release has been extensively studied, but arthroscopic techniques are limited, particularly in differentiating between post-traumatic and non-traumatic stiffness. The purpose of this study is to assess the clinical outcomes after arthroscopic release of PTES regarding the range of motion (ROM), pain, functional assessment, and complications. METHODS A prospective cohort was conducted on adult patients who underwent arthroscopic arthrolysis for PTES, with 32 patients included in the final analysis. The ROM was measured using the orthopedic goniometer. Grip strength was measured using the Camry digital hand dynamometer (Camry, CA, USA) and compared to their contralateral side. The functional status of the patients was evaluated using the American Shoulder and Elbow Surgeons Score (ASES)andthe Mayo Elbow Performance Index (MEPI). All measurements were done before surgery and at the last follow-up visit. Pre-operative and post-operative changes in MEPI, ASES, and visual analog (VAS) scores were compared with the paired t-test. RESULTS After surgery, the ROM significantly improved from 74 ± 11 to 110 ± 15 degrees (p<0.001). Additionally, the ASES score and MEPI index both significantly improved from 69 ± 3.4 to 79 ± 6.3 and from 64 ± 5.7 to 82 ± 8, respectively (p<0.001). VAS scores also significantly improved from 1.1 ± 0.87 to 0.31 ± 0.53 at rest (p<0.001). The complication rate was 12%, including three transient ulnar nerve paresthesia and one superficial infection. Post-traumatic elbow release was more offered in distal humerus fractures (53%), followed by proximal ulna fracture/dislocations (25%). CONCLUSION We believe that arthroscopic arthrolysis is a safe and reliable treatment of PTES, which improves joint visibility and reduces pain. Patients can be counseled regarding the risk of a secondary surgery following distal humerus or proximal ulna fractures, including the expected recovery and complication rate.

Abstract
Kidney stone is a highly recurrent disease in the urinary tract system. Most kidney stones are calcium stones, usually consisting of either calcium oxalate or calcium phosphate. Supersaturation of soluble calcium, oxalate, phosphate, and citrate in the urine is the basis for calcium stone formation. Genetics, diet, low physical activity, and individual habits contribute to the formation of kidney stones. In this review, the associations of the risk of kidney stones with oxalate consumption and some individual habits, such as smoking, alcohol drinking, and opium consumption, are summarized.

Abstract
Bladder cancer, prostate cancer, and kidney cancer, due to their high morbidity and mortality rates, result in significant economic and health care costs. Arsenic exposure affects the drinking water of millions of people worldwide. Long-term exposure to arsenic, even in low concentrations, increases the risk of developing various cancers. Smoking is also one of the leading causes of bladder, prostate and kidney cancers. Accordingly, this research reviews the relationship between arsenic exposure and smoking with three kinds of urinary tract cancers (bladder cancer, prostate cancer, and kidney cancer) due to their widespread concern for their negative impact on public health globally. In this review, we have gathered the most current information from scientific databases [PubMed, Scopus, Google Scholar, ISI web of science] regarding the relationship between arsenic exposure and tobacco smoking with the risk of bladder, prostate, and kidney cancer. In several studies, a significant relationship was determined between the incidence and mortality rate of the above-mentioned cancers in humans with arsenic exposure and tobacco smoking. The decrease or cessation of smoking and consumption of arsenic-free water significantly declined the incidence of bladder, prostate, and kidney cancers.

Abstract
Background: We used antibiotic-impregnated polymethylmethacrylate (PMMA) bone cement to make a patient-specific radial head prosthesis (RHP) by applying the 3-dimensional (3D) designing technique in patients with Mason types 3 and 4 radial head fractures. The aim of this study is to report the short- to mid-term outcomes of this procedure. Methods: This is a prospective study of all patients who underwent a patient-specific PMMA bone cement RHP at our institute over a 1-year period from May 2017 to June 2018. The outcome measures included range of motion, grip strength, visual analogue scale (VAS) for pain at rest and at activity, disabilities of arm, shoulder and hand (DASH) score and Mayo elbow performance index (MEPI). Radiographs of the elbow ere obtained at final follow-up and any complications were also recorded. Results: Our study included eight patients with a mean follow-up of 18 months (13-20 months). The mean arc of extension-flexion and supination-pronation of the operated side was 86% and 96% of the unaffected side, respectively. Mean grip strength was 86% of the unaffected side. The mean VAS for pain at rest was 0 and during activity was 2 out of 10. The mean DASH score was 8 out of 100 (0-22), showing minimal disability and ability to cope with most living activities. MEPI showed four excellent, three good and one fair result. One patient complained of proximal forearm pain that appeared 1 year after surgery. No patient complained of ulnar nerve symptoms requiring intervention. No RHP was removed during the follow-up. Conclusions: PMMA RHP can be used safely as an alternative to metal prostheses to restore valgus and axial stability of the forearm. The use of 3D printing optimised the design and surgical technique of radial head arthroplasty, and we need further studies to assess the long-term follow-ups. Level of Evidence: Level IV (Therapeutic).

Abstract
PURPOSE The differentiation of resin remnants from enamel is a critical factor to minimize enamel damage after bracket debonding. This study was conducted to produce, and ascertain the efficacy of two colouring agents in minimizing enamel loss, adhesive and bonding remnants, and surface roughness after debonding. METHODS Two dyes containing annatto (orange colour) and curcumin (yellow colour) were produced. Seventy-two maxillary premolars were divided into three groups. After bracket bonding and debonding, the adhesive remnant was removed with a fine diamond bur. In groups 1 and 2, the orange and yellow dyes were utilized during the removal process, respectively. In group 3 (control) adhesive was removed with no colouring agent. The buccolingual dimension of the teeth was measured at the occlusal, middle, and apical areas, before bonding and after clean-up. The adhesive remnant index (ARI) and bonding remnant index (BRI) scores were recorded and the surface roughness parameters were measured. Data were analysed by ANOVA, Tukey, and Fisher's exact tests (α=0.05). RESULTS Enamel loss was significantly lower in the groups cleaned by the use of colouring agents than that of the control group (P<0.05). No bonding agent was observed when the dyes were used, whereas 65% of teeth in the control group showed the remaining bonding material (P<0.001). There was no significant difference in ARI scores or surface roughness alterations among the study groups (P>0.05). CONCLUSION The two dyes produced in this study were effective in enhancing the visibility of residual resin materials and minimizing enamel loss during the clean-up process.

Abstract
The van der Waals magnets CrX3 (X = I, Br, and Cl) exhibit highly tunable magnetic properties and are promising candidates for developing novel two-dimensional (2D) spintronic devices such as magnetic tunnel junctions and spin tunneling transistors. Previous studies of the antiferromagnetic CrCl3 have mainly focused on mechanically exfoliated samples. Controlled synthesis of high quality atomically thin flakes is critical for their technological implementation but has not been achieved to date. This work reports the growth of large CrCl3 flakes down to monolayer thickness via the physical vapor transport technique. Both isolated flakes with well-defined facets and long stripe samples with the trilayer portion exceeding 60 µm have been obtained. High-resolution transmission electron microscopy studies show that the CrCl3 flakes are single crystalline in the monoclinic structure, consistent with the Raman results. The room temperature stability of the CrCl3 flakes decreases with decreasing thickness. The tunneling magnetoresistance of graphite/CrCl3 /graphite tunnel junctions confirms that few-layer CrCl3 possesses in-plane magnetic anisotropy and Néel temperature of 17 K. This study paves the path for developing CrCl3 -based scalable 2D spintronic applications.

Abstract
Introduction This study aimed to compare the diagnostic value of four questionnaires for the diagnosis of neurocognitive disorders (NCDs) in the elderly. Methods In this project, people older than 60 years who lived in Tehran were investigated. A total of 99 literate cases were enrolled in the study, and four questionnaires, including functional assessment staging tool (FAST), abbreviated mental test score (AMTS), mini-mental state examination (MMSE), and modified Persian test of elderly for assessment of cognition and executive function (PEACE) were completed for them. They were then referred to a neuropsychiatrist, and the status of their cognition and neurobehavior was determined. The specialists were blinded to the results of the tests. Results Of the 99 participants studied, 39 cases were healthy, eight cases had mild Alzheimer's disease, 38 had amnesic MCI, five cases had secondary dementia, and nine cases had mixed vascular dementia and Alzheimer's disease. The area under the ROC curve for distinguishing the healthy group from the rest of the population was 0.692, 0.629, 0.734, and 0.751 for the FAST, AMTS, MMSE, and NBCSS questionnaires, respectively. Conclusion MMSE and NBCSS tests had better diagnostic power than the other two tests to distinguish the healthy group from the rest of the population.

Abstract
Earlier research has suggested that the male reproductive system could be particularly vulnerable to SARS-CoV-2 (COVID-19) infection, and infections involving this novel disease not only pose serious health threats but could also cause male infertility. Data from multi-organ research during the recent outbreak indicate that male infertility might not be diagnosed as a possible consequence of COVID-19 infection. Several review papers have summarized the etiology factors on male fertility, but to date no review paper has been published defining the effect of COVID-19 infection on male fertility. Therefore, the aim of this study is to review the published scientific evidence regarding male fertility potential, the risk of infertility during the COVID-19 pandemic, and the impact of COVID-19 vaccination on the male reproductive system. The effects of COVID-19 infection and the subsequent vaccination on seminal fluid, sperm count, sperm motility, sperm morphology, sperm viability, testes and sex hormones are particularly reviewed.

Abstract
Objectives Today, one of the most important challenges in the world and in Iran is the increase of older population. With the death of a spouse in old age, the social participation of the elderly decreases; living alone is associated with a high risk of death and an impact on all aspects of health (physical, mental, social) in the elderly. This study aims to investigate the barriers to remarriage in older Iranian women. Methods & Materials The present study was conducted in 2019 with a qualitative approach and using the content analysis method. Using a purposive sampling method, 10 older women living in Babol city with at least one year of being single, widowed or divorced, the ability to communicate effectively, willingness to participate in research were selected. The data collection method was in-depth semi-structured interviews until reaching data saturation. Each interview was transcribed and analyzed based on Kvale’s step-by-step guidance. Results In order to determine the trustworthiness of the data, the criteria of credibility, dependability, confirmability, and transferability were used. From the interviews, 210 primary codes were extracted. Through analysis, three main categories and 12 sub categories were identified. The three categories were: “characteristics, changes and perspectives of the elderly”, “family and mutual roles of members”, “social relations and its effects”. Conclusion Considering the shame, modesty, and the taboo of remarriage in older women in Iran and the lack of transparency regarding their desires, planning and promoting culture to improve the quality of life of older women, breaking the taboo of remarriage by changing people’s views and common prejudices, and not violating the older women’s rights seem necessary.

Abstract
Ferroelectric HfO2-based materials hold great potential for the widespread integration of ferroelectricity into modern electronics due to their compatibility with existing Si technology. Earlier work indicated that a nanometre grain size was crucial for the stabilization of the ferroelectric phase. This constraint, associated with a high density of structural defects, obscures an insight into the intrinsic ferroelectricity of HfO2-based materials. Here we demonstrate that stable and enhanced polarization can be achieved in epitaxial HfO2 films with a high degree of structural order (crystallinity). An out-of-plane polarization value of 50 μC cm-2 has been observed at room temperature in Y-doped HfO2(111) epitaxial thin films, with an estimated full value of intrinsic polarization of 64 μC cm-2, which is in close agreement with density functional theory calculations. The crystal structure of films reveals the Pca21 orthorhombic phase with small rhombohedral distortion, underlining the role of the structural constraint in stabilizing the ferroelectric phase. Our results suggest that it could be possible to exploit the intrinsic ferroelectricity of HfO2-based materials, optimizing their performance in device applications.

Abstract
Low molecular weight branched polyethylenimine (LMW bPEIs 1.8 kDa) have received considerable attention for the fabrication of nucleic acid carriers due to their biocompatible and non-toxic nature. However, due to the inadequate nucleic acid complexation ability and transportation across the cell membrane, these show poor transfection efficacy, limiting their clinical applications. Therefore, to overcome these challenges, in this study, we have grafted bPEI 1.8 kDa with a disulfide bond containing hydrophobic moiety, 3-(2-pyridyldithio) propionic acid (PDPA), via amide linkages through EDC/NHS-mediated coupling to obtain N-[3-(2-pyridyldithio)] propionoyl polyethylenimine (PDPP) conjugates. The best formulation for nucleic acid transfection was evaluated after preparing a series of PDPP conjugates by varying the amount of PDPA. In an aqueous environment, these PDPP conjugates self-assembled to form spherical shaped core-shell PDPP nanostructures with size ranging from ∼188-307 nm and zeta-potential from ∼ +3 to +19 mV. The positively charged surface of the core-shell nanocomposites helps in the binding of plasmid DNA (pDNA), its transportation inside the cell, and protection against enzymes. Evaluation of PDPP/pDNA complexes on mammalian cells revealed that all these complexes showed significantly improved transfection efficacy without hampering cytocompatibility. Amongst all, the pDNA complex of PDPP-2 exhibited the best transfection efficiency (i.e. >6-fold) in comparison to pDNA complex of the native bPEI. The nanocomposites exhibited the redox responsive behavior advantageous for therapeutic delivery to the tumor cells. The core of the nanostructures facilitate the encapsulation of a hydrophobic model drug, ornidazole. In vitro drug release analysis showed a faster release rate in response to a reductant mimicking the cellular environment. Altogether, these nanostructures have great potential to co-deliver both drug and gene simultaneously in response to tumor cell reductive microenvironment in vitro and could be used as the next-generation delivery system.

Abstract
BACKGROUND Sleep quality is an important factor in adolescents' health; physical as well as psychological. The aim of this study was to determine sleep quality and daytime sleepiness and their effect on the quality of school life (QSL) and achievement. MATERIALS AND METHODS This cross-sectional study was conducted in high schools. The data collection was done on a random sample of 500 students from 15 to 19 years. The questionnaires included the Pittsburgh Sleep Quality Index (PSQI) to measure sleep quality and the Epworth Sleepiness Scale to measure daytime sleepiness as well as QSL. Data were analyzed by SPSS 25. Linear and logistic regressions were used to obtain adjusted and unadjusted odds ratios as well as predictors. RESULTS The mean PSQI score was 6.2 ± 2.4. It was realized that 377 participants (75.4%) were poor sleepers; 6.2% had excessive daytime sleepiness. There was a significant association between age and quality of sleep (P < 0.04). No association between gender and quality of sleep or between the quality of sleep and school achievement was found. Linear regression exhibited a significant relationship between the quality of sleep and daytime sleepiness (β = 0.218; t = 4.982, P = 0.000). There was a significant, inverse correlation between sleepiness and the total score of QSL (P = 0.000). Stepwise linear regression analysis exhibited that daytime sleepiness (P = 0.002) and school achievement (P = 0.001) were predictors of QSL. CONCLUSION According to the study results, sleepiness affects school performance and QSL, and on the other hand, daytime sleepiness is under the effect of sleep quality.

Abstract
BACKGROUND AND AIMS This systematic review and meta-analysis aimed to evaluate the current evidence available to investigate clinical outcomes between patients with type 1 and type 2 diabetes. METHODS MEDLINE (Pubmed), Scopus, Web of Science, Cochrane library, Google scholar and Clinicaltrials.gov were searched. Randomized controlled trials (RCTs), non-randomized trials, and observational studies were eligible for inclusion. National Institutes of Health Quality Assessment Tool was used to assess the quality. Data were pooled by the Restricted-maximum-likelihood random-effects approach. RESULTS Total 11 studies comprising 7690415 individuals were included in this study. The log OR for the pooled data for all-cause mortality rate was -0.71 (95% CI: -1.38 to -0.03). Based on the pooled results, type 1 diabetic COVID-19 patients may have a better prognosis for mortality. There were no significant differences between groups in term of ICU-admission log OR -0.22 (95% CI: -0.81 to 0.37), and hospitalization log OR -0.48 (95% CI: -1.23 to 0.27). Based on our descriptives analyses after adjusting for age and comorbidities, the high-risk group in three studies was type 2 diabetes, and in five studies was type 1. Two studies reported no significant difference between these groups in relevant outcomes. CONCLUSION There were no significant differences in disease severity between type 1 and type 2 diabetes. Based on the unadjusted data available, the mortality rate for people with type 1 diabetes was shown to be lower than that for people with type 2. As data on these subjects is scarce, and the results obtained from studies are heterogeneous, further research with adequate sample sizes is needed to precisely compare the outcomes of COVID-19 between type 1 and type 2 diabetes.

Abstract
Autophagy, known as a "self-eating" process, is associated with degradation of aged or damaged components and organelles. Generally, autophagy is a survival mechanism that provides energy during nutritional deprivation. This mechanism plays a remarkable role during the physiological condition by maintaining homeostasis and energy balance and several pathological conditions, particularly neurological disorders. Due to the critical role of autophagy in cancer, much attention has been made in the regulation of autophagy using both naturally occurring and synthetic drugs. Quercetin is a plant-derived chemical belonging to the family of flavonoids. Quercetin has valuable biological and therapeutic effects such as anti-tumor, antioxidant, anti-inflammatory, anti-diabetic, hepatoprotective, and cardioprotective. At the present review, we first provide an introduction about quercetin and autophagy with its related molecular pathways. We also describe how quercetin modulates autophagy mechanism to exert its therapeutic effects.

Quantum chemical density functional theory (DFT) calculations were performed to investigate the adsorption of arsine (AsH3) gaseous substance at the surface of representative models of boron nitride (B16N16), aluminum nitride (Al16N16), and silicon carbide (Si16C16) fullerene-like nanocages. The results indicated that the adsorption processes of AsH3 could be taken place by each of B16N16, Al16N16, and Si16C16 nanocages. Moreover, the electronic molecular orbital properties indicated that the electrical conductivity of nanocages were changed after the adsorption processes enabling them to be used for sensor applications. To analyze the strength of interacting models, the quantum theory of atoms in molecules (QTAIM) was employed. As a typical achievement of this work, it could be mentioned that the investigated Si16C16 fullerene-like nanocage could work as a suitable adsorbent for the AsH3 gaseous substance proposing gas-sensor role for the Si16C16 fullerene-like nanocage.

Abstract
This study aimed to investigate the prevalence of COVID-19 in domestic cats, focusing on the disease in the northwest of Iran and then showing the natural transmission of SARS-COV-2 circulating between domestic cats and humans. After receiving ethic codes from Tehran University of Medical Sciences (IR.TUMS.VCR.REC.1399.303) and confirmed by the Center of Communicable Diseases Control (CDC) of Iran, 124 domestic cats were collected from the homes and only one hospital of Meshkin -Shahr district from northwestern Iran where SARS-CoV-2 patients were hospitalized and quarantined during 2020. Samples were prepared from fluid materials of oropharynx and nasopharynx. All samples were tested by real-time PCR (RT-PCR) using specific genes N and ORF1ab in Pasteur Institute of Iran, and then partial sequence analyses of S gene were performed. All collected cats were kept in separated cages until SARS-COV-2 infection was confirmed with the RT-PCR. RT- PCR Ct values of 123 collected cats were ≥40; thus, all of them showed negative results, but one of the collected cats with close contact with its owner, whom confirmed SARS-CoV-2 showed positive results with gene N(Ct=30) and gene ORF1ab (Ct=32). Furthermore, the positive pet cat showed respiratory and gastro-intestinal clinical manifestations, and its owner was infected with SARS-CoV-2 two weeks ago. Cats are susceptible animals to SARS-CoV-2 infection. Epidemiological evidence showed that SARS-COV-2 is able to transmit to healthy cats due to having close contact with its owner as a reverse zoonosis.

Abstract
Nuclear factor erythroid-2 related factor 2 (Nrf2) is a major signaling pathway for the maintenance of homeostasis and redox balance. This pathway also plays a significant role in proteostasis, xenobiotic/drug metabolism, apoptosis, and lipid and carbohydrate metabolism. Conversely, the Nrf2 signaling pathway is impaired in several pathological conditions including cancer. Although various drugs have been developed to target the Nrf2 pathway, plant-derived chemicals than can potentially impact this pathway and are particularly attractive due to their minimal side effects. Ginsenosides are active components of ginseng and have been shown to exert pharmacological effects including antioxidant, anti-inflammatory, antitumor, antidiabetes, neuroprotective, and hepatoprotective activities. In this article, we have reviewed the effects of ginsenosides on Nrf2 signaling pathway.

Abstract
MicroRNAs (miRNAs) are endogenous short noncoding RNAs with approximately 22 nucleotides. The primary function of miRNAs is the negative regulation of target gene expression via mRNA degradation or translation inhibition. During recent years, much attention has been made toward miRNAs' role in different disorders; particularly cancer and compounds with modulatory effects on miRNAs are of interest. Melatonin is one of these compounds which is secreted by the pineal gland. Also, melatonin is present in the leaves, fruits, and seeds of plants. Melatonin has several valuable biological activities such as antioxidant, anti-inflammation, antitumor, and antiaging activities. This important agent is extensively used to treat different disorders such as cancer and neurodegenerative and cardiovascular diseases. This review aims to describe the modulatory effect of melatonin on miRNAs as novel targets.

Abstract
Background: Acute Coronary Syndrome (ACS) is the first leading cause of death in the industrial world. It is associated with low self-esteem and self-efficacy. Given that patient education is a key role of nurses, this study sought to evaluate the effects of multimedia education on self-efficacy and self-esteem among patients with ACS. Materials and Methods: This randomized clinical trial was conducted in 2017 on 60 patients recruited from the two coronary care units of Hajar and Kashani hospitals, Shahrekord, Iran. Participants were randomly allocated to an intervention and a control group. The study intervention was a multimedia educational program. Data were collected before and 1 and 2 months after the intervention onset using a demographic questionnaire, the Cardiac Self-Efficacy Scale, and Coopersmith Self-Esteem Inventory. Data analyses were performed using repeated measures analysis of variance, t-test, Chi-square test, and Fisher's exact test. Results: The mean score of self-efficacy in the intervention group (F2 = 119.26, p < 0.001) and in the control group (F2 = 74.21, p < 0.001) significantly increased across the three measurement time points. The mean score of self-esteem in the intervention group significantly increased across the three measurement time points (F2 = 101.19, p < 0.001), while it remained significantly unchanged in the control group (F2 = 2.56, p = 0.086). Conclusions: Multimedia education is effective in significantly improving self-efficacy and self-esteem among patients with ACS. Therefore, nurses can use this strategy to improve these patients’ self-efficacy and self-esteem.

Abstract
PURPOSE Oilseeds and their related products are known to have various bioactive and health-promoting ingredients. In this research, we investigated the effects of phytosterols and fatty acids of Pistacia vera on spermatogenesis process and testis histological changes in Wistar male rats for the first time. MATERIALS AND METHODS A total number of 64 adult male Wistar rats were divided randomly into eight groups including one control group, and seven test groups. Test groups received phytosterols, fatty acids, and pistachio oil orally for 30 days. Then, LH, FSH, and serum testosterone levels were determined. Also, the spermatogenesis process and changes in testicular tissue in rats were investigated. RESULTS The results of this research suggest that phytosterols in doses of 10 and 50 mg/kg reduce the spermatogenesis process. Fatty acid in a low dose of 10 mg/kg increases spermatogenesis, but when a high dose of 50 mg/kg was used, it harmed the spermatogenesis process. When low levels of phytosterols and fatty acids are used simultaneously in dose 5 mg/kg, improvement in spermatogenesis process is observed but when these were used together in the dose of 25 mg/kg, the spermatogenesis process was disrupted. Using pistachio oil alone also improved spermatogenesis process. CONCLUSION It seems that phytosterols reduce spermatogenesis at high and low doses, while fatty acids increase spermatogenesis when used in low doses and reduce this process when used in high doses. The use of fatty acids extracted from pistachios to treat infertility in men seems hopeful.

Abstract
Since the COVID-19 pandemic initiation, the possibility of re-infection has been unclearly present. Although herd immunity has a potential reliance through natural infection, human corona viruses has the ability to subvert immunity and re-infection happens for seasonal corona viruses. Currently, the frequency of SARS-CoV-2 re-infection incidence is not exactly defined. In this study we aimed at determination of SARS-CoV-2 re-infection rate in Iranian population. In a total of 5696 COVID-19 suspicious individuals, RT-PCR was applied to diagnose the infection. The confirmed patients were followed for 12 months and serology tests were applied to measure the specific antibodies. Among 1492 confirmed COVID-19 cases, five individuals experienced the subsequent infection. The re-infection/reactivation incidence rate was totally 0.33% after one year of follow-up. The interval ranged from 63 to 156 days. All the cases had viral mutations in the second episode of the infection. All of them were symptomatic cases with moderate severity. The estimated rate of SARS-CoV-2 in Persian population is therefore rare and natural infection seems to induce good protection against re-infection which clarifies that mass vaccination can hugely affect the society.

Abstract
A model of heterogeneous carbon-boron-nitrogen (C-B-N) nanocage was investigated in this work for adsorbing H2O and H2S substances. To achieve this goal, quantum chemical calculations were performed to obtain optimized configurations of substances towards the surface of nanocage. The calculations yielded three possible configurations for relaxing each of substances towards the surface. Formation of acid-base interactions between vacant orbitals of boron atom and full orbitals of each of oxygen and sulfur atoms yielded the strongest complexes of substance-nanocage in comparison with orientation of substances through their hydrogen atoms towards the surface of nanocage. As a consequence, formations of interacting H2O@C-B-N and H2S@C-B-N complexes were achievable, in which mechanism of action showed different strengths for the obtained complexes. Variations of molecular orbital features and corresponding energy gap and Fermi energy for the models before/after adsorption could help for detection of adsorbed substance through a sensor function. And finally, such C-B-N nanocage showed benefit of providing activated surface for efficient adsorption of each of H2O and H2S substance with possibility of differential adsorption regarding the strength of complex formations.

Abstract
AIM The chemokine-receptor axes play parts in development of leukemia, CXCL1, CXCL10 and CXCL12 are involved in immune responses. Thus, we have examined the serum levels of these chemokines in parallel with their related cognate receptors (CXCR1, CXCR3 and CXCR4) in AML (acute myeloid leukemia) patients prior and post BMT (bone marrow transplantation) therapy. MAIN METHODS Clinical specimens were collected from 46 AML patients (23 M1 and 23 M3 subtypes) before/after BMT. CXCL1, CXCL10 and CXCL12 concentrations were determined by ELISA. The mRNA levels of the related receptors were detected by QRT_PCR. Data were analyzed by T-test, χ2 and ANOVA statistical methods in SPSS software version 18. A difference was regarded significant if P value < 0.05. KEY FINDINGS Our results indicated that the elevated levels of CXCL12 in AML patients were remained unchanged after transplantation. The CXCL10 concentration was decreased in patients. All studied chemokines were elevated in BMT patients with history of 9 times PLT transfusion. In patients who received BMT from siblings CXCL1 and CXCL10 have been elevated, whereby they were compared to patients who received BMT from parents while CXCL12 sustained unchanged in groups. Serum measures of CXCL1 and CXCL10 were induced in acute and chronic GVHD patients in compare to these without GVHD. SIGNIFICANCE According to the results, it can be concluded that these chemokines play fundamental parts in pathogenesis of both AML and BMT. It is worthy to note that chemokines could be used as diagnostic markers alongside with possible promising therapeutic targets.

Abstract
D-optimal mixture design looked to be a priceless tool for optimizing the influences of semolina flour (SF), defatted soy flour (DSF), whole quinoa flour (WQF), whole rye flour (WRF), whole oat flour (WOF), whole barley flour (WBF), and rice flour (RF) on the quality attributes of multigrain pasta (MP). Multigrain flours were considered as the independent variables evaluated with respect to three response variables containing hardness and the amount of protein and fiber. Quadratic, linear, and linear models were chosen to explain the hardness and the amount of protein and fiber of the MPs, respectively. In optimal formulation of MP, that is, SF (57.34%,), DSF (14%), WQF (11%), WRF (7.54%), WOF (5.61%), WBF (2.51%), and RF (2%), the content of fiber and protein enhanced more than 4.12 and 1.34 times compared with SP, respectively. Therefore, according to the European Union law, it can be claimed that this pasta is a source of fiber. As the amount of protein and fiber increased, the hardness and optimal cooking time decreased, while the cooking loss increased. After cooking, MP was murkier and less yellow in color. The 2, 2- diphenyl- 1- picrylhydrazyl (DPPH) inhibition activity of the MP was about 2.5 times higher than the SP. Analysis of the antioxidant properties of the samples after cooking showed that the DPPH inhibition activity of the SP and MP reduced. The results indicated that the overall acceptability of MP was higher than SP. Based on our findings, these multigrain flours are probable to be applied as nutritious complements in the pasta industry to improve the functional characteristics.

Abstract
The healthcare system aims to provide a reliable and organized solution to enhance the health of human society. Studying the history of patients can help physicians to consider patients' needs in healthcare system designing and offering service, which leads to an increase in patient satisfaction. Therefore, healthcare is becoming a growing contesting market. With this significant growth in healthcare systems, such challenges as huge data volume, response time, latency, and security vulnerability are raised. Therefore, fog computing, as a well-known distributed architecture, could help to solve such challenges. In fog computing architecture, processing components are placed between the end devices and cloud components, and they execute applications. This architecture is suitable for such applications as healthcare systems that need a real-time response and low latency. In this paper, a systematic review of available approaches in the field of fog-based healthcare systems is proposed; the challenges of its application in healthcare are explored, classified, and discussed. First, the fog computing approaches in healthcare are categorized into three main classes: communication, application, and resource/service. Then, they are discussed and compared based on their tools, evaluation methods, and evaluation metrics. Finally, based on observations, some open issues and challenges are highlighted for further studies in fog-based healthcare.

Abstract
Classification approaches that allow to extract logical rules such as decision trees are often considered to be more interpretable than neural networks. Also, logical rules are comparatively easy to verify with any possible input. This is an important part in systems that aim to ensure correct operation of a given model. However, for high-dimensional input data such as images, the individual symbols, i.e. pixels, are not easily interpretable. Therefore, rule-based approaches are not typically used for this kind of high-dimensional data. We introduce the concept of first-order convolutional rules, which are logical rules that can be extracted using a convolutional neural network (CNN), and whose complexity depends on the size of the convolutional filter and not on the dimensionality of the input. Our approach is based on rule extraction from binary neural networks with stochastic local search. We show how to extract rules that are not necessarily short, but characteristic of the input, and easy to visualize. Our experiments show that the proposed approach is able to model the functionality of the neural network while at the same time producing interpretable logical rules. Thus, we demonstrate the potential of rule-based approaches for images which allows to combine advantages of neural networks and rule learning.

Abstract
The flexible, transparent, and low-weight nature of ferroelectric polymers makes them promising for wearable electronic and optical applications. To reach the full potential of the polarization-enabled device functionalities, large-scale fabrication of polymer thin films with well-controlled polar directions is called for, which remains a central challenge. The widely exploited Langmuir-Blodgett, spin-coating, and electrospinning methods only yield polymorphous or polycrystalline films, where the net polarization is compromised. Here, an easily scalable approach is reported to achieve poly(vinylidene fluoride-trifluoroethylene) P(VDF-TrFE) thin films composed of close-packed crystalline nanowires via interface-epitaxy with 1T'-ReS2 . Upon controlled thermal treatment, uniform P(VDF-TrFE) films restructure into about 10 and 35 nm-wide (010)-oriented nanowires that are crystallographically aligned with the underlying ReS2 , as revealed by high-resolution transmission electron microscopy. Piezoresponse force microscopy studies confirm the out-of-plane polar axis of the nanowire films and reveal coercive voltages as low as 0.1 V. Reversing the polarization can induce a conductance switching ratio of >108 in bilayer ReS2 , over six orders of magnitude higher than that achieved by an untreated polymer gate. This study points to a cost-effective route to large-scale processing of high-performance ferroelectric polymer thin films for flexible energy-efficient nanoelectronics.

Abstract
Curcumin is a naturally occurring polyphenol that is isolated from the rhizome of Curcuma longa (turmeric). This medicinal compound has different biological activities, including antioxidant, antibacterial, antineoplastic, and anti-inflammatory. It also has therapeutic effects on neurodegenerative disorders, renal disorders, and diabetes mellitus. Curcumin is safe and well-tolerated at high concentrations without inducing toxicity. It seems that curcumin is capable of targeting the Nrf2 signaling pathway in protecting the cells against oxidative damage. Besides, this strategy is advantageous in cancer therapy. Accumulating data demonstrates that curcumin applies four distinct ways to stimulate the Nrf2 signaling pathway, including inhibition of Keap1, affecting the upstream mediators of Nrf2, influencing the expression of Nrf2 and target genes, and finally, improving the nuclear translocation of Nrf2. In the present review, the effects of curcumin on the Nrf2 signaling pathway to exert its therapeutic and biological activities has been discussed.

Abstract
Β2-Glycoprotein I (β2GPI) is an important anti-thrombotic protein and is the major auto-antigen in the antiphospholipid syndrome (APS). The clinical relevance of nitrosative stress in post translational modification of β2GPI was examined.The effects of nitrated (n)β2GPI on its anti-thrombotic properties and its plasma levels in primary and secondary APS were determined with appropriate clinical control groups. β2-glycoprotein I was nitrated at tyrosines 218, 275 and 309. β2-glycoprotein I binds to lipid peroxidation modified products through Domains IV and V. Nitrated β2GPI loses this binding (p < 0.05) and had diminished activity in inhibiting platelet adhesion to vWF under high shear flow (p < 0.01). Levels of nβ2GPI were increased in patients with primary APS compared to patients with either secondary APS (p < 0.05), autoimmune disease without APS (p < 0.05) or non-autoimmune patients with arterial thrombosis (p < 0.01) and healthy individuals (p < 0.05).In conclusion tyrosine nitration of plasma β2GPI is demonstrated and has important implications with regards to the pathophysiology of platelet mediated thrombosis in APS. Elevated plasma levels of nβ2GPI in primary APS may be a risk factor for thrombosis warranting further investigation.

Abstract
Drug-induced aseptic meningitis (DIAM) is a rare complication of certain drugs, most commonly reported with ibuprofen use. The present study reports on a male adolescent with intracranial hypertension and visual impairment accompanied by DIAM. We present a 16-year-old male patient who after ibuprofen consumption displayed headache, fever, photophobia, and blurred vision following heavy exercises. Examination of cerebrospinal fluid showed a mononuclear pleocytosis and an increase in protein concentration. Other examinations had normal results. The development of common clinical signs following ibuprofen use reflected DIAM. The patient's vision was found to improve with supportive care and stopping of the drug during follow-up. Given the widespread use of nonsteroidal anti-inflammatory drugs and the fact that these drugs are the most common cause of DIAM, the probability of occurrence of this event should be always kept in mind, and screening for autoimmune diseases in these patients is of great importance.

Abstract
BACKGROUND MicroRNAs are endogenous, short, non-coding RNAs with the length as low as 20 to 25 nucleotides. These RNAs are able to negatively affect the gene expression at the post-transcriptional level. It has been demonstrated that microRNAs play a significant role in cell proliferation, cell migration, cell death, cell differentiation, infection, immune response, and metabolism. Besides, the dysfunction of microRNAs has been observed in a variety of cancers. So, modulation of microRNAs is of interest in the treatment of disorders. OBJECTIVE The aim of the current review is to investigate the modulatory effect of propofol on microRNAs in cancer therapy. METHODS This review was performed at PubMed, SCOPUS and Web of Science data-bases using keywords "propofol', "microRNA", "cancer therapy", "propofol + microRNA" and "propofol + miR". RESULTS It was found that propofol dually down-regulates/upregulates microRNAs to exert its antitumor activity. In terms of oncogenesis microRNAs, propofol exert an inhibitory effect, while propofol significantly enhances the expression of oncosuppressor microRNAs. CONCLUSION It seems that propofol is a potential modulator of microRNAs and this capability can be used in the treatment of various cancers.

Abstract
Albumin is an attractive protein for the preparation of nanoparticle with possible therapeutic applications, due to its biodegradable, nontoxic, non-immunogenic, and metabolizable properties. Many studies have investigated the formation of albumin nanoparticles, generally by the desolvation or coacervation approaches. One of the most important parameters that should be considered in the formation of nanoparticles is their morphology (size and shape). There are many proposals to control the nanoparticle size, but it remains a challenge for researchers yet. In this study, we showed that control of BSA-based nanoparticles/microparticles size could be achieved by varying the temperature and pH and therefore controlling the rate of aggregation. The aggregation behavior was monitored by UV-Vis spectroscopy, SEM, and dye-binding assay. Our results provide more options for the size and shape control of BSA-based nanoparticle in natural buffer systems. The aggregation of BSA at different temperatures within the range of 50-80 °C were studied under the effect of different pHs in the range of 4.7-6.2. In this research, we found that protein aggregation under extreme conditions of pH and temperature, or at the pH near to pI appears to be amorphous, and at the pH above the pI seems to be the amyloid fibril structure. In some instances where the aggregation is neither too fast nor too slow, in the initial phase of the aggregation process, nanoparticle structures can be identified and separated by mechanistic approaches. This observation suggests that the best condition for monitoring the formation of albumin-based nanoparticles could be pH 5.7, 70 °C. Satisfactory rationalization of all aspects of our experimental observation requires further and more detailed study.

Abstract
Astaxanthin (AST) is a naturally occurring compound isolated from various sources such as fungi, plants, salmon, and crab. However, Haematococcus Pluvialis, a green alga, is the primary source of this beta carotenoid compound. AST has several favourable biological and pharmacological activities such as antioxidant, anti-inflammatory, anti-tumor, anti-diabetes, hepatoprotective and neuroprotective. Nevertheless, the exact molecular mechanisms of these protective effects of AST are unclear yet. The Nrf2 signaling pathway is one of the critical candidate signaling pathways that may be involved in these beneficial effects of AST. This signaling pathway is responsible for maintaining the redox balance in the physiologic state. Upon nuclear translocation, Nrf2 signaling activates antioxidant enzymes to reduce oxidative stress and protect cells against damage. In the current study, we have reviewed the effects of AST on the Nrf2 signaling pathway, which could potentially be developed as a novel therapeutic approach for the management of various diseases.

Abstract
The world has gone through the critical phase of SARS-CoV-2 crisis caused by the new variants of the virus. The globally concerted effort to characterize viral genomic mutations across different clades has revealed several changes in the coding and also non-coding regions which might lead to a violent presentation or re-infection occurrence. Here, we studied a COVID-19 subject who represented the symptoms following the full recovery of the first infection. COVID-19 specific IgM and IgG were evaluated in both steps. The viral samples from oropharyngeal/nasopharyngeal were subjected to RT-PCR and full sequencing was done in both incidences. The sequencing data was fully investigated with the reference sequence of SARS-CoV-2 and the changes were detected. The obtained data is in favor of re-infection with 128 days of interval. SARS-CoV-2 presented more severely in the second episode of the disease and the specific antibodies against COVID-19 were not detectable. Both infections were caused by the same clade 20G, however, the mutation rates were higher in the second incidence including 10 nucleotide substitutions which had rarely been reported before. In the present study, the nucleotide mutations in various regions of the viral genome have been presented. The re-infection could have significant effect on clinical implications as well as vaccination.

Abstract
Flavonoids consist a wide range of naturally occurring compounds which are exclusively found in different fruits and vegetables. These medicinal herbs have a number of favourable biological and therapeutic activities such as antioxidant, neuroprotective, renoprotective, anti-inflammatory, anti-diabetic and anti-tumor. Troxerutin, also known as vitamin P4, is a naturally occurring flavonoid which is isolated from tea, coffee and cereal grains as well as vegetables. It has a variety of valuable pharmacological and therapeutic activities including antioxidant, anti-inflammatory, anti-diabetic and anti-tumor. These pharmacological impacts have been demonstrated in in vitro and in vivo studies. Also, clinical trials have revealed the efficacy of troxerutin for management of phlebocholosis and hemorrhoidal diseases. In the present review, we focus on the therapeutic effects and biological activities of troxerutin as well as its molecular signaling pathways.

Abstract
BACKGROUND Breast cancer is accounted as the fifth leading cause of mortality among the other cancers. Notwithstanding, Triple Negative Breast Cancer (TNBC) is responsible for 15-20% of breast cancer mortality. Despite many investigations, it remains incurable in part due to insufficient understanding of its exact mechanisms. METHODS A literature search was performed in PubMed, SCOPUS and Web of Science databases using the keywords autophagy, Endoplasmic Reticulum (ER) stress, apoptosis, TNBC and the combinations of these keywords. RESULTS It was found that autophagy plays a dual role in cancer, so that it may decrease the viability of tumor cells or act as a cytoprotective mechanism. It then appears that using compounds having modulatory effects on autophagy is of importance in terms of induction of autophagic cell death and diminishing the proliferation and metastasis of tumor cells. Also, ER stress can be modulated in order to stimulate apoptotic and autophagic cell death in tumor cells. CONCLUSION Perturbation in the signaling pathways related to cell survival leads to the initiation and progression of cancer. Regarding the advancement in the cancer pathology, it seems that modulation of autophagy and ER stress are promising.

Abstract
The aim of this study was to compare the predictive performance of ridge regression best linear unbiased prediction-method 6 (rrBLUPm6) with well-known genomic selection methods (rrBLUP, GBLUP and BayesA) in terms of accuracy of prediction, computing time and memory requirement. The impact of the genetic architecture and heritability on the accuracy of genomic evaluation was also studied. To this end, a genome was simulated which consisted of five chromosomes, one Morgan each, on which 5000 biallelic singlenucleotide polymorphisms (SNP) were distributed. Prediction of genomic breeding values was done in different scenarios of number of QTL (50 and 500 QTL), distribution of QTL effects (uniform, normal and gamma) and different heritability levels (0.1, 0.3 and 0.5). Pearson's correlation between true and predicted genomic breeding values (rp,t) was used as the measure of prediction accuracy. Computing time and memory requirement were also measured for studied methods. The accuracy of rrBLUPm6 was higher than GBLUP and rrBLUP, and was comparable with BayesA. In addition, regarding computing time and memory requirement, rrBLUPm6 outperformed other methods and ranked first. A significant increase in accuracy of prediction was observed following increase in heritability. However, the number and distribution of QTL effects did not affect the accuracy of prediction significantly. As rrBLUPm6 showed a great performance regarding accuracy of prediction, computing time and memory requirement, we recommend it for genomic selection.

Abstract
Introduction: Premature birth is highly stressful for parents. Nursing support is crucial for premature infants. Parental satisfaction is a vital indicator of the quality of care provided by nurses. Therefore, determining the factors related to parental satisfaction is important in nursing care. Objective: This study aims to investigate the relationship between social support and parentschr('39') satisfaction with the medical care provided to their premature infants in the Neonatal Intensive Care Units (NICUs). Materials and Methods: This is an analytical/correlational study. Participants were 130 parents of premature infants admitted to the NICUs in three hospitals affiliated to Tehran University of Medical Sciences in Iran. They were selected based on a convenience sampling method. Tarkka’s Social Support Questionnaires and the Neonatal Index of Parent Satisfaction were used for collecting data. Data were analyzed by using descriptive statistics and T-test, Chi-square test, ANOVA and Pearson correlation test. Results: It was reported that 55.38% of the infants were females, with a mean birth weight of 1880.97± 544.85 gr and a mean gestational age of 32.07±2.41 weeks. The mean age of their mothers and fathers was 31.25±5.12 and 35.03±5.66 years, respectively. The highest level of social support in mothers and fathers was related to emotional support (3.65±0.69 in mothers and 3.29±0.57 in fathers), while the lowest level of social support was related to concrete support (3.32±0.80 in mothers and 3.16±0.65 in fathers). Mothers perceived higher social support than fathers. They also had more satisfaction with medical care (3.88±0.81 in mothers and 3.63±0.69 in fathers). There was a significant relationship between social support and parental satisfaction (r=0.791, P<0.05). Conclusion: Parents of premature infants need more social support, especially concrete aid. Therefore, planning to promote social support of parents, especially fathers, by nurses in the NICUs seems necessary.

Abstract
Flavonoids are a large group of naturally occurring compounds, which are of interest due to their great pharmacological effects and health-promoting impacts. These properties have led to their extensive application in a variety of pathological conditions, particularly cancer. Flavonoids are used in large quantities in a human's daily diet and a high amount of flavonoids are found in the intestine after oral usage. However, flavonoid concentrations in tissue/plasma are low because of their low bioavailability, the leading to the low efficacy of flavonoids in different clinical disorders. For this reason, nanotechnology application for delivering flavonoids to tumor sites has recently received significant attention. Silibinin is a key member of flavonoids and a bioactive component of silymarin, which is widely isolated from Silybum marianum. This plant-derived chemical has a number of valuable biological and therapeutic activities such as antioxidant, anti-inflammatory, neuroprotective, anti-tumor, hepatoprotective, cardioprotective and anti-diabetic. These beneficial effects have been demonstrated in in vivo and in vitro experiments. However, it seems that silibinin has a variety of limitations and poor bioavailability is the most important factor restricting its wide application. Hence, there have been attempts to improve the bioavailability of silibinin and it has been suggested that nano-soldiers are potential candidates for this aim. In the present review, we describe the different drug delivery systems for improving the bioavailability of silibinin.

Abstract
Curcumin, isolated from the rhizome of Curcuma longa, is one of the most extensively studied phytochemicals. This natural compound has a variety of pharmacological effects including antioxidant, anti-inflammatory, anti-tumor, cardio-protective, hepato-protective and anti-diabetic. Wnt signaling pathway, one of the potential targets of curcumin through upregulation and/or downregulation, plays a significant role in many diseases, even in embryogenesis and development of various organs and systems. In order to exert an anti-tumor activity in the organism, curcumin seems to inhibit the Wnt pathway. The downstream mediators of Wnt signaling pathway such as c-Myc and cyclin D1 are also modified by curcumin. This review demonstrates how curcumin influences the Wnt signaling pathway and is beneficial for the treatment of neurological disorders (Alzheimer's and Parkinson's diseases), cancers (melanoma, lung cancer, breast cancer, colon cancer, endothelial carcinoma, gastric carcinoma and hepatocellular carcinoma) and other diseases, such as diabetes mellitus or bone disorders.

Abstract
Background: Cholestatic liver disease primarily affects hepatic tissue. Cholestasis could also influence the function of other organs rather than the liver. Cholestasis-induced kidney injury is a severe clinical complication known as "cholemic nephropathy" (CN). Bile duct ligation (BDL) is a trustworthy experimental model for inducing CN. Although the precise mechanism of renal injury in cholestasis is not fully recognized, several studies revealed the role of oxidative stress in CN. There is no promising pharmacological intervention against CN. Carnosine (CAR) is a peptide extensively investigated for its pharmacological effects. Radical scavenging and antioxidative stress are major features of CAR. The current study aimed to evaluate the role of CAR supplementation on the CN. Methods: CAR was administered (250 and 500 mg/kg, i.p) to BDL rats for 14 consecutive days. Urine and serum markers of renal injury, biomarkers of oxidative stress in the kidney tissue, and renal histopathological alterations were monitored. Results: Significant elevation in oxidative stress biomarkers, including ROS formation, lipid peroxidation, oxidized glutathione (GSSG) levels, and protein carbonylation were found in the kidney of BDL rats. Moreover, renal tissue antioxidant capacity and reduced glutathione (GSH) levels were significantly decreased in the organ of cholestatic animals. Renal histopathological changes, including tubular atrophy, interstitial inflammation, tissue fibrosis, and cast formation, were detected in the kidney of BDL rats. It was found that CAR administration significantly protected the kidney of cholestatic animals. Conclusion: The antioxidative properties of this peptide might play a fundamental role in its protective properties during cholestasis.

Abstract
There are concerns about the spread of heavy metals in the environment, and human activities are one of the most important factors in their spread. These agents have the high half-life resulting in their persistence in the environment. So, prevention of their spread is the first step. However, heavy metals are an inevitable part of modern and industrial life and they are applied in different fields. Cadmium is one of the heavy metals which has high carcinogenesis ability. Industrial waste, vehicle emissions, paints, and fertilizers are ways of exposing human to cadmium. This potentially toxic agent harmfully affects the various organs and systems of body such as the liver, kidney, brain, and cardiovascular system. Oxidative stress is one of the most important pathways of cadmium toxicity. So, improving the antioxidant defense system can be considered as a potential target. On the other hand, the Nrf2 signaling pathway involves improving the antioxidant capacity by promoting the activity of antioxidant enzymes such as catalase and superoxide dismutase. At the present review, we demonstrate how Nrf2 signaling pathway can be modulated to diminish the cadmium toxicity.

Abstract
Application of conducting ferroelectric domain walls (DWs) as functional elements may facilitate development of conceptually new resistive switching devices. In a conventional approach, several orders of magnitude change in resistance can be achieved by controlling the DW density using supercoercive voltage. However, a deleterious characteristic of this approach is high-energy cost of polarization reversal due to high leakage current. Here, we demonstrate a new approach based on tuning the conductivity of DWs themselves rather than on domain rearrangement. Using LiNbO3 capacitors with graphene, we show that resistance of a device set to a polydomain state can be continuously tuned by application of subcoercive voltage. The tuning mechanism is based on the reversible transition between the conducting and insulating states of DWs. The developed approach allows an energy-efficient control of resistance without the need for domain structure modification. The developed memristive devices are promising for multilevel memories and neuromorphic computing applications.
