Abstract
BACKGROUND Cancer is a considerable health problem worldwide and the second leading cause of death in children. It has many physical, psychological, and social consequences for children and their families. The ability to adapt to cancer plays a vital role in the recovery and quality of life of affected children. This study aimed to explain the adaptation of children with cancer to their disease. METHODS This qualitative study adopted the directed content analysis approach based on the Roy nursing model. The participants were nine children with cancer aged 6-18 years old, five family members, four nurses, one doctor, one teacher, and two charity association members, recruited by purposive sampling method. The information was collected via individual semi-structured interviews, a focus group discussion, and field notes. The data were analyzed simultaneously with data collection using the Elo and Kyngäs method. The study rigor was ensured based on the Guba and Lincoln criteria. FINDINGS Of the four categories of physical challenges, fragile self-concept, the difficulty of role transition, and disruption of the path to independence, the theme of Falling and rising in the cancer vortex was abstracted. CONCLUSION Based on the Roy model, the children in the present study were at the compensatory level of adaptation. This research demonstrates that the adaptation of children being treated for cancer is fragile and not constant. With each hospitalization and exacerbation of the disease, they made efforts to adapt to their disease using regulatory and cognitive subsystems. Paying attention to different stimulants and the effects of support systems on physical challenges, fragile self-concept, difficult role transition, and disruption of the path to independence for each child, as well as providing individualized care for these children, can help their adaptation to and healthy transition from the vortex of cancer. The Roy adaptation model was helpful and efficient for elucidating the adaptation of children with cancer. Providing care for children by healthcare specialists, especially nurses, should be theory-based and individualized.

Abstract
This study shows a molecular dynamics (MD) simulation study on the performance of the RHO zeolite membrane for separating nitrogen from methane/nitrogen gas mixtures. The contamination of natural gas, predominantly composed of methane, with nitrogen diminishes its value. Zeolite membranes offer promising prospects for gas separation due to their stability, rigid pore structure, and molecular sieving properties. The study investigates the impact of pressure difference (up to 30 MPa), feed composition, and membrane thickness on the separation rate at a system temperature of 298 K. Results demonstrate that the RHO zeolite membrane exhibits high permeability and selectivity for N2 separation, surpassing the upper limit defined by Robson with a maximum permeability of 2.14 × 105 GPU (Gas Permeation Units). Exceptional selectivity of N2 over CH4 molecules is observed. Additionally, altering the feed composition and membrane thickness positively influences the membrane's separation performance, thereby enhancing its efficiency. The findings contribute to the advancement of separation technologies, providing valuable insights into the potential application of zeolite membranes for efficient N2 separation from CH4/N2 gas mixtures in natural gas processing. Furthermore, the study explores the use of Deep Neural Network (DNN) models to predict the membrane's performance under diverse operating conditions. The DNN models, trained using simulation data from MD simulations, exhibit high accuracy with a coefficient of determination (R2) exceeding 0.9, ensuring reliable predictions. The integration of DNN models facilitates the optimization of zeolite membrane-based gas separation systems, improving their design and operation.

Abstract
IMPORTANCE Saprophytic fungi can cause nosocomial infections in high-risk patients. These infections are related to high mortality and cost. In the current study, different species of filamentous fungi and yeast were isolated from the environment of the studied hospitals. Some species were resistant to antifungal drugs. We suggest that the future work concentrates on the relationship between the level/quantification of saprophytic contamination in the environment of hospitals and fungal infections in patients.

Abstract
BACKGROUND Intertrochanteric fracture is a common injury among the elderly, causing fundamental lifestyle derangements, influencing the patients' social and psychological functioning. We aimed to study the quality of life (QoL) and its different parameters in patients with this type of injury. MATERIALS AND METHODS In this cross-sectional study, all patients hospitalized with intertrochanteric fracture aged above 50 from 2020 to 2022 at the Shahid Beheshti Hospital in Babol, Iran, were included. Patients were primarily managed surgically and, in exceptional cases non-surgically, were followed up for at least 12 months after receiving treatment. During the follow-up period, patients were dialled and completed a questionnaire to assess the patient's QoL by the 36-item Short Form Health Survey (SF-36). QoL parameters were analyzed based on patients' sex, age, type of treatment, and height of fall causing fracture. RESULT A total number of 200 patients, including 101 (50.5%) males and 99 (49.5%) females, with a mean age of 74.76±11.36 years (range: 50-99), were included. Regarding the received treatment, 192 (96.0%) patients underwent surgery, and 8 (4.0%) underwent non-surgical treatment. In the study of SF-36 scores, the mean score of male patients was 42.31±14.58, and females scored 37.83±15.35, and the difference was statistically significant (P = 0.04). The mean score of QoL and its subscales among the 50-75 group patients was significantly higher than the 76-99 group (P<0.001). The average score of QoL was considerably higher in patients who had surgery (40.75±14.57) compared to those who had non-surgical treatment (24.30±19.85) (P = 0.01). Patients having a fall from a higher height had higher QoL after treatment. CONCLUSION This study revealed that patients with an intertrochanteric femoral fracture had poor QoL in all aspects. The overall QoL was significantly higher among male patients, younger patients, those who underwent surgical treatment, and the falls from higher heights. These findings highlight the necessity of long-term follow-up and support in patients with intertrochanteric fractures.

Abstract
Changes in perceived eye height influence visually perceived object size in both the real world and in virtual reality. In virtual reality, conflicts can arise between the eye height in the real world and the eye height simulated in a VR application. We hypothesized that participants would be influenced more by variation in simulated eye height when they had a clear expectation about their eye height in the real world such as when sitting or standing, and less so when they did not have a clear estimate of the distance between their eyes and the real-life ground plane, e.g., when lying supine. Using virtual reality, 40 participants compared the height of a red square simulated at three different distances (6, 12, and 18 m) against the length of a physical stick (38.1 cm) held in their hands. They completed this task in all combinations of four real-life postures (supine, sitting, standing, standing on a table) and three simulated eye heights that corresponded to each participant's real-world eye height (123cm sitting; 161cm standing; 201cm on table; on average). Confirming previous results, the square's perceived size varied inversely with simulated eye height. Variations in simulated eye height affected participants' perception of size significantly more when sitting than in the other postures (supine, standing, standing on a table). This shows that real-life posture can influence the perception of size in VR. However, since simulated eye height did not affect size estimates less in the lying supine than in the standing position, our hypothesis that humans would be more influenced by variations in eye height when they had a reliable estimate of the distance between their eyes and the ground plane in the real world was not fully confirmed.

Abstract
The Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) is responsible for ongoing epidemics in humans and some other mammals and has been declared a public health emergency of international concern. In this project, several small non-peptide molecules were synthesized to inhibit the major proteinase (Mpro) of SARS-CoV-2 using rational strategies of drug design and medicinal chemistry. Mpro is a key enzyme of coronaviruses and plays an essential role in mediating viral replication and transcription in human lung epithelial and stem cells, making it an attractive drug target for SARS-CoV. The antiviral potential of imidazoline derivatives as inhibitors of (SARS-CoV-2) Mpro was evaluated using in-silico techniques such as molecular docking simulation, molecular dynamics (MD), and ADMET prediction. The docking scores of these imidazoline derivatives were compared to that of the N3 crystal inhibitor and showed that most of these compounds, particularly compound E07, interacted satisfactorily in the active site of the coronavirus and strongly interacted with the residues (Met 165, Gln 166, Met 165, His 41, and Gln 189). Furthermore, the results were confirmed by MD simulations after exposure to long-term MD simulations and ADMET predictions.

Abstract
Nitrofurantoin (NF), a wide-spectrum antibiotic accessible since 1953, is utilized widely to treat urinary tract infections as it usually stays active against drug-resistant uropathogen. The use of Nitrofurantoin has increased exponentially since new guidelines have repositioned it as first-line therapy for uncomplicated lower urinary tract infection (UTI). To, although fluoroquinolones are usually used to re-evaluate the first- and second-line therapies for treating uncomplicated UTI, their level of utilization is thought to be inappropriately excessive and will eventually have a detrimental impact; thus, we hypothesize that NF might be the best choice for this condition, because of its low frequency of utilization and its high susceptibility in common UTI pathogens. It can be concluded from this review that NF can be considered as the most effective drug in the treatment of acute urinary infection, but due to the long-term side effects of this drug, especially in elderly patients, it is essential to introduce some criteria for prescribing NF in cases of chronic UTI.

Abstract
The adaptive mutation phenomenon has been drawing the attention of biologists for several decades in evolutionist community. In this study, we propose a quantum mechanical model of adaptive mutation based on the implications of the theory of open quantum systems. We survey a new framework that explain how random point mutations can be stabilized and directed to be adapted with the stresses introduced by the environments according to the microscopic rules dictated by constraints of quantum mechanics. We consider a pair of entangled qubits consist of DNA and mRNA pair, each coupled to a distinct reservoir for analyzing the spreed of entanglement using time-dependent perturbation theory. The reservoirs are physical demonstrations of the cytoplasm and nucleoplasm and surrounding environments of mRNA and DNA, respectively. Our predictions confirm the role of the environmental-assisted quantum progression of adaptive mutations. Computing the concurrence as a measure that determines to what extent the bipartite DNA-mRNA can be correlated through entanglement, is given. Preventing the entanglement loss is crucial for controlling unfavorable point mutations under environmental influences. We explore which physical parameters may affect the preservation of entanglement between DNA and mRNA pair systems, despite the destructive role of interaction with the environments.

Abstract
BACKGROUND Kangaroo care (KC) is an effective technique to prevent injury in newborns due to prematurity and hospitalization. Mothers of preterm newborns experience their own set of physical and mental problems. Such circumstances call for another family member to take care of the newborn. This study compared the effect of KC by mothers and maternal grandmothers on the vital signs of preterm newborns. METHODS This parallel randomized controlled trial was done at the neonatal and NICU departments of the hospital in Kuhdasht in Iran. Eighty preterm neonates were selected through convenience sampling according to the eligibility criteria, then by stratified block randomization allocated to two groups. The control group received KC from the mother, and the intervention group received KC from the maternal grandmothers on the vital signs of preterm newborns. Vital signs were assessed 15 min before, during, and after the KC as the primary outcome. The data collection tools included a demographic questionnaire and a form to record the vital signs. Vital signs were measured by a pulse oximeter, an electronic thermometer, and observation. Data were analyzed by the chi-square test, the independent t-test, and the repeated measures ANOVA. RESULTS The vital signs of newborns in each group showed a significant difference before, during, and after receiving KC (P < 0.05). Nevertheless, the vital signs of the newborns did not differ significantly between the mother and the maternal grandmother KC groups (P > 0.05). CONCLUSION KC by maternal grandmother may stabilize the vital signs of preterm newborns as much as when this type of care is provided by the mother. We, therefore, recommend the provision of KC by the maternal grandmother, as a support and substitute for the mother whenever she is incapable of being at the hospital and to enable the mother to rest.

Abstract
Although previous studies have suggested that dietary acid load may be associated with mental health, the relationship between food-induced acid production and odds of attention-deficit hyperactivity disorder remains (ADHD) unclear. The aim of the present study was to evaluate the relationship between dietary renal acid load and odds of ADHD among children. A case-control study was designed to assess the data of 500 children aged 4 to 12 years (200 children with diagnosed ADHD and 300 control group). Patients were clinically diagnosed according to the Diagnostic and Statistical Manual-5th Edition criteria. Subjects in the control group did not have any history of chronic diseases and they were screened for the absence of ADHD. Dietary intake was assessed by a semi-quantitative food frequency questionnaire. The odds of incident ADHD for each unit increase of potential acid load (PRAL) in the raw model showed ~9.8% (OR = 1.098, 95% CI: 1.072, 1.125, p < .001) higher odds of ADHD. In model 1, where age, gender, Body mass index (BMI), and socio-economic status were adjusted, the odds of ADHD was ~10.7% (OR = 1.107, 95% CI: 1.076, 1.140, p < .001). Also, in model 2 (model 1 in addition to energy) the odds was ~10.8% (OR = 1.108, 95% CI: 1.065, 1.152, p < .001). Findings of the present study suggest a possible relationship between oxidative stresses and odds of development of ADHD. Furthermore, the size of the odds ratio is small. It appears that dietary considerations are warranted in order to ameliorate the impact and/or incidence of ADHD.

Abstract
In clinical practice, bone defects that occur alongside tumors, infections, or other bone diseases present significant challenges in the orthopedic field. Although autologous and allogeneic grafts are introduced as common traditional remedies in this field, their applications have a series of limitations. Various approaches have been attempted to treat large and irregularly shaped bone defects; however, their success has been less than optimal due to a range of issues related to material and design. However, in recent years, additive manufacturing has emerged as a promising solution to the challenge of creating implants that can be perfectly tailored to fit individual defects during surgical procedures. By fabrication of constructs with specific designs using this technique, surgeons are able to achieve much better outcomes for patients. Polymers, ceramics, and metals have been used as biomaterials in Orthopedic Surgery fields. Polymeric scaffolds have been used successfully in total joint replacements, soft tissue reconstruction, joint fusion, and as fracture fixation devices. The use of polymeric biomaterials, either in the form of pre-made solid scaffolds or injectable pastes that can harden in situ, shows great promise as a substitute for commonly used autografts and allografts. Polymethyl methacrylate (PMMA) is one of the most widely used polymer cement in orthopedic surgery. The present paper begins with an introduction and will then provide an overview of the properties, advantages/disadvantages, applications, and modifications of PMMA bone cement.

Abstract
Background Fever is the most common reason for children’s visits to medical centers. Its management is an essential duty of a pediatric nurse. The aim of this study was to determine the effect of body wash with Marshmallow plant on children’s fever. Methods This parallel clinical trial was performed on 92 children aged 6 months to 10 years with a tympanic temperature above 38.3 °C. Participants were randomly assigned to groups. Simultaneously with receiving acetaminophen, body wash was performed in the control group with lukewarm water and in the intervention group with white Marshmallow extract. The children’s temperature; from the beginning of the study was checked and recorded every 15 min in the first hour and in the 4th and 6th hours. The time duration to resolve fever, the frequency of afebrile children at different times of the study, and the value of temperature reduction were primary outcomes. Heart rate, the need to administer the next dose of acetaminophen, and the time of fever recurrence were recorded as secondary outcomes. Results The mean time duration to resolve fever in the intervention group was shorter than in the control group (B = 8.181, 95% CI 3.778–12.584, p < 0.001). The frequency of the children without fever was higher in the intervention group during different times of the study (p < 0.001). The mean value of temperature reduction in the intervention group was higher than the control group (B = -0.27 °C, 95% CI: -0.347 to -0.193, P < 0.001), although, after adjusting the effect of confounding variables it was not significant (P = 0.127). The mean of adjusted heart rate change (p = 0.771), the time of fever recurrence (P = 0.397), and the frequency of children requiring the next dose of acetaminophen (p = 0.397) did not show a significant difference between the groups. Conclusion Body wash with Marshmallow extract reduced children’s fever in a shorter period of time and to some extent a greater extent than the control group without side effects. Therefore, it can be used as an effective and safe complementary method to help reduce fever. However, more studies are necessary for this field.

Abstract
BACKGROUND Invasive aspergillosis is one of the important causes of infection in immunocompromised patients. This study aimed to evaluate the roles of biomarkers in the diagnosis of invasive aspergillosis and their relationship with antifungal stewardship programs. METHODS 190 sera from 52 immunocompromised patients and volunteer individuals were included in this study. 18 immunocompromised volunteers without IA and 34 patients with probable and proven aspergillosis according to the European Organization for Research and Treatment of Cancer and the Mycoses Study Group consensus definitions were entered in this study. The respective sera were evaluated for procalcitonin, soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) levels; white blood cells count (WBC) count, C reactive protein (CRP), lactate dehydrogenase (LDH), and erythrocyte sedimentation rate (ESR) values. Demographic data and clinical characteristics of patients were extracted from their files. RESULTS The male-to-female ratio and mean age of patients were 22/12 and 38.9 years, respectively. The hematologic disorder was the most predisposing factor (29/34, 85.3%). Sensitivity of biomarkers for diagnosis of invasive aspergillosis was 70.6% (cut off value > 190 pg/mL for sTREM-1, 71% (cut off value > 260 pg/mL) for PCT, 85.3% (cut off value > 193 U/L) for LDH, 94.1% (cut off value > 8 mg/l) for CRP, 64.7% (cut off value < 5200 cells/ml) for WBC, and 85.3% (cut off value > 23 mm/h) for ESR. Twelve patients died, with significantly increased sTREM-1 levels and decreased WBC count in them. CONCLUSION According to our data, evaluation of the biomarkers can help in the diagnosis, management, and prediction of the severity of Aspergillus infection, and the rational use of antifungal agents in immunocompromised patients.

Abstract
Background Coronavirus infection has caused widespread concern among mothers and physicians about the health of pregnant women and infants. Objective The aim of this study was to evaluate the clinical and prenatal findings of pregnant women with coronavirus disease-2019 (COVID-19) virus. Materials and Methods The present study was a descriptive study that was conducted in 6 mother and child care centers. In this study, 81 pregnant women with COVID-19 admitted to centers in the period from March 2020-September 2020 were studied. Clinical and prenatal findings of the pregnant mothers were recorded using a data collection form with details of demographic characteristics and these were analyzed. Results The gestational age of the affected women was between 4 and 40 wk. 48 deliveries were performed and 25% of deliveries were preterm. Coronavirus infection was the cause of termination of pregnancy in 4 cases. The most common symptoms of women when visiting the medical centers were: dry cough (58.0%), muscle pain and myalgia (56.8%) and fever (51.9%). The most common laboratory findings in the women were: increased C-reactive protein (67.90%), lymphopenia (18.51%), decreased white blood cells (27.16%), and increased liver enzymes (18.51%). Regarding the status of the newborns, out of the 33 neonates examined, 3 neonates were diagnosed with COVID-19. Conclusion The most common symptoms of pregnant women with COVID-19 are similar to those of other adults. In relation to neonatal infection, given that a number of the neonates tested positive, there appears to be evidence of vertical transmission, which requires further investigation.

Abstract
Background: Crohn’s disease (CD) has a chronic course, which its recurrence varies widely among different patients. In this study we prospectively analyzed blood samples of 19 CD patients. Alteration in transcription of inflammatory and anti-inflammatory cytokines was analyzed compared with household members after three month follow up. Methods: CD patients were diagnosed based on clinical symptoms, endoscopic and histopathologic characteristics. Nineteen CD patients and their households were evaluated from Jun 2019 to Feb 2021 at Tehran university hospitals. CD activity score, biological, clinical and demographic data of the patients were recorded at two time point intervals. Bacteriological tests were done using aerobic and anaerobic blood cultures. To investigate transcriptional alterations, peripheral blood mononuclear cells (PBMCs) were isolated using Ficol centrifugation method and relative quantitative real-time PCR was done to determine the expression level of IFN-γ, TNF-α, IL10, and FOXP3 cytokines. Results: Our results showed a correlation between fecal calprotectin level (709.8 ± 554.6), C-reactive protein concentration (18.1 ± 15.9), and erythrocyte sedimentation rate (30.4 ± 17.9) with disease activity (Flare/remission). IL10 and Foxp3 anti-inflammatory gene’s expression were significantly (P = 0.003 for IL10 and P = 0.008 Foxp3) higher during the flare and remission in patients with active disease respectively. Bacteriological examination showed infection with Streptococcus spp. and Clostridium spp. in two CD patients during flares, which was correlated with upregulation and down-regulation of IL10, TNF-α, IFN-γ and FOXP3 proteins, respectively. Conclusion: Occurrence of bacteremia, and higher amount of CAP, CRP and ESR are correlated with higher level of transcription for inflammatory cytokines, which could effectively reflect the disease activity. Raise in FoxP3 transcription proposed change in Treg sub-population in PBMC or its activity during the CD remission phase.

Abstract
Aspergillus species are a major cause of life-threatening invasive infections and noninvasive diseases. This study seeks to investigate the frequency of Aspergillus species among Iranian patients and their susceptibility to seven antifungals. In a cross-sectional study, 233 Aspergillus isolates were collected from 11 university hospitals in Iran between 2018 and 2021. Aspergillus isolates were identified based on colony morphology, microscopic characteristics, PCR-restriction fragment length polymorphism (RFLP), and sequencing of the beta-tubulin gene. The CLSI M38-A2 reference methodology was used for antifungal susceptibility testing of amphotericin B, voriconazole, posaconazole, itraconazole, luliconazole, isavuconazole, and caspofungin. Members of Aspergillus section Flavi (117/233, 50.2%), Aspergillus section Nigri (77/233, 33.1%), Aspergillus section Fumigati (21/233, 9%), Aspergillus section Terrei (14/233, 6%), Aspergillus pseudodeflectus (2/233, 0.85%), and Aspergillus melleus (2/233, 0.85%) were isolated from the samples. The lowest 0.25 MIC90 values for all isolates tested were for luliconazole (0.016 μg/mL) and isavuconazole (0.250 μg/mL), and the highest value was observed for itraconazole (≥ 8μg/mL). The 90% minimum effective concentration (MEC90) value for caspofungin was 0.125 μg/mL. MIC90 values for voriconazole, amphotericin B, and posaconazole were 1, 2, and 2 μg/mL, respectively. The non-wild-type species were presented for amphotericin B (3%), voriconazole (1.3%), posaconazole (2.6%), luliconazole (1.3%), isavuconazole (1.7%), and caspofungin (4.7%). Positive correlations in the MIC values of azole antifungals were observed, and using one azole increases the MIC value rates of other ones. None of the species were pan-azole resistant. Species of Aspergillus section Flavi were the most common Aspergillus species isolated from Iranian samples. Luliconazole, caspofungin, and isavuconazole present the most effective antifungal agents for treatment of infection due to Aspergillus species. Susceptibility tests should be performed frequently in each region for the best management of patients. IMPORTANCE Aspergillus species are the leading cause of invasive aspergillosis in immunocompromised hosts. The susceptibility of Aspergillus species to antifungal agents might be different. Azole-resistant species have emerged worldwide. Performing susceptibility testing in each region can help in the best management of patients. Here, we show the epidemiology and distribution of Aspergillus species in Iran and their susceptibility patterns for seven antifungal agents. The significant points of the present study are that species of Aspergillus section Flavi are the most prevalent Aspergillus species isolated from 11 university hospitals. Luliconazole, caspofungin, and isavuconazole were effective antifungal agents against all Aspergillus species.

Abstract
Background Betatrophin may be associated with metabolic diseases. Objective To investigate the betatrophin level and its association with metabolic and inflammatory parameters in infertile women with polycystic ovary syndrome (PCOS) and other infertile women during the intrauterine insemination cycle. Materials and Methods This case-control study was conducted with 90 infertile women (45 with PCOS and 45 without) chosen by convenience sampling, in the infertility clinic of Imam Khomeini Hospital in Tehran, Iran. Participants were interviewed to obtain their age, body mass index, and reproductive history. Fasting brachial venous blood samples were obtained on the 3 rd day of the menstrual cycle to measure the levels of betatrophin, fasting blood sugar, insulin, luteinizing hormone, follicle-stimulating hormone, low-density lipoprotein cholesterol, estradiol, and high-sensitivity C-reactive protein. Results The results showed that the level of betatrophin in women with PCOS was significantly higher than in the control group (p = 0.05). Based on multiple linear regression analyses, the effects of metabolic and inflammatory parameters on betatrophin were not significant (p = 0.19). The results showed no significant difference between groups in folliculogenesis (p = 0.57). Conclusion According to the results, betatrophin levels were higher in infertile women with PCOS than in those without. The findings suggest that there may be an association between increased betatrophin and increased incidence of PCOS. Further studies with a larger sample size are needed to investigate the role of betatrophin in insulin resistance and lipid metabolism, and its effects on infertility treatment outcomes.

Group I, nondiabetic rats; Group II, diabetic rats; Group III, diabetic rats receiving an intraperitoneal (i.p.) injection of metformin (45 mg/kg); Groups IV, V and VI were diabetic rats receiving i.p. injection of 5, 10, and 20 mg/kg of the complex for 3 weeks, respectively. Fasting blood glucose (FBG), insulin, liver enzymes, malondialdehyde (MDA), total antioxidant capacity (TAC), lipid profile, and HbA1c were measured. RESULTS AST, ALT and GGT activities and MDA levels were increased, while TAC was decreased in diabetic animals. Treatment of diabetic rats improved the HOMA-IR and returned HbA1c level to the normal value as well as elevated TAC and reduced MDA level. CONCLUSION We found that the complex possesses antidiabetic properties in experimental diabetes.

Abstract
Tight control of gene expression networks required for adipose tissue formation and plasticity is essential for adaptation to energy needs and environmental cues. However, the mechanisms that orchestrate the global and dramatic transcriptional changes leading to adipocyte differentiation remain to be fully unraveled. We investigated the regulation of nascent transcription by the sumoylation pathway during adipocyte differentiation using SLAMseq and ChIPseq. We discovered that the sumoylation pathway has a dual function in differentiation; it supports the initial downregulation of pre-adipocyte-specific genes, while it promotes the establishment of the mature adipocyte transcriptional program. By characterizing endogenous sumoylome dynamics in differentiating adipocytes by mass spectrometry, we found that sumoylation of specific transcription factors like PPARγ/RXR and their co-factors are associated with the transcription of adipogenic genes. Finally, using RXR as a model, we found that sumoylation may regulate adipogenic transcription by supporting the chromatin occurrence of transcription factors. Our data demonstrate that the sumoylation pathway supports the rewiring of transcriptional networks required for formation of functional adipocytes. This study also provides the scientists in the field of cellular differentiation and development with an in-depth resource of the dynamics of the SUMO-chromatin landscape, SUMO-regulated transcription and endogenous sumoylation sites during adipocyte differentiation.

Abstract
Menopause is a natural event experienced by women in middle age. To help women manage this event, it is important to identify their health information needs. A study specific questionnaire was used to identify menopausal women’s health information needs and the resources and challenges related to finding information about menopause. A total of 301 women aged 48–55 years completed the questionnaire. Data were analysed using negative binomial regression and chi-square tests. The most frequently sought information was that related to breast cancer (n = 209, 69.5%), hot flushes (n = 200, 66.5%), cervical cancer (n = 194, 64.5%), non-hormonal therapies for menopausal symptoms (n = 192, 64%), laboratory tests (n = 189, 63%) and joint and muscle pain (n = 188, 62.5%). The main sources of information were audiovisual media (n = 171, 57%), obstetricians (n = 165, 55%), friends (n = 157, 52%), family (n = 157, 52%) and the internet (n = 153, 51%). The two main challenges were not knowing how to correctly access information (n = 115, 38%) and not being aware of reliable sources of information (n = 108, 36%). Therefore, it is essential for policymakers and decision-makers to provide reliable and accurate information to increase awareness and reduce anxiety of women experiencing menopause.

Abstract
INTRODUCTION The present study aimed to compare the effect of two different forms of face-to-face and counseling on a social application, i.e., WhatsApp, on self-care and quality of life of women with gestational diabetes. METHODS The present research was an educational trial with control group, which was conducted on diabetic women between 24 and 26 weeks of pregnancy. A total of 126 subjects were included in the study using the convenient sampling method. They were assigned into three groups. All of the participants answered the questionnaires gestational diabetes self-care, and quality of life at the beginning and end of the study. The GATHER approach to counseling (G = Greeting, A = Ask, T = Tell, H = Help, R = Return) was performed in four 45-min sessions for face-to-face and WhatsApp groups in the pregnancy weeks of 27, 28, 29, and 30. The subjects in the control group received only the routine cares for gestational diabetes. T test, Chi squared test, and ANOVA repeated measurement test were used to analyze the data. RESULTS Findings showed a significant difference among the three groups in self-care and quality of life (p = 0.001). There was also a significant difference among the three groups in fasting blood sugar after the intervention (p = 0.005). CONCLUSION Self-care counseling, both in the form of face-to-face and on social networks, improved the score of self-care and quality of life as well as glucose tolerance test (GTT) in women with gestational diabetes.

Abstract
INTRODUCTION Helicobacter pylori is considered a major agent causing gastritis and peptic ulcer disease. Unfortunately, the occurrence of increasing drug resistance to this bacterium would result in some difficulties in its treatment. Therefore, the application of nanotechnology has been suggested to resolve such problems. Nanoparticles usage in medical research has been expanded in recent years. Among nanometals, gold nanoparticles have exclusive features that can be used in such applications. Using nanotechnology in medical science could help mankind to solve this problem in the future. AIM Our aim in this research was to investigate the antimicrobial effect of gold nanoparticles on H. pylori strains. MATERIALS AND METHODS Gold nanoparticles were synthesized by the Turkevich method. Then, their size and dispersion were investigated using spectrophotometry, DLS, and TEM microscopy. Subsequently, the combination of metronidazole and gold nanoparticles was obtained by mixing method, and then the anti-helicobacter effects of the two were evaluated according to CLSI. RESULTS The highest size of gold nanoparticles was between 12 and 9 nm, and the maximum absorbance was 522 nm; however, in conjugated state, the maximum absorbance was 540 nm, which indicated the accumulation of drug-conjugated nanoparticles in the conjugate state. Some changes indicated the binding of metronidazole to gold nanoparticles. Antimicrobial testing of gold nanoparticles and metronidazole did not affect the Helicobacter pylori. Therefore, the combination of gold nanoparticles and metronidazole had a 17-mm growth inhibition zone. CONCLUSIONS The anti-helicobacter effects of metronidazole significantly increased in conjugation with gold nanoparticles.

Abstract
Background Crohn's disease (CD) is a chronic inflammatory disease without a specific cause. Inflammation in these patients can disturb the oxidants/antioxidants balance and results in oxidative stress that plays a destructive role. This study aimed to evaluate the gene expression of sod1, sod2, cat, nrf2 and gp91phox in CD patients before and after Azathioprine (Aza) consumption. Method Peripheral bloodmononuclear cells (PBMCs) were separated from CD patients (n= 15, mean age = 33.6 ± 1.8) before and after treatment with Aza and healthy controls (n= 15, mean age = 31.5 ± 1.2). The expression levels of sod1, sod2, cat, nrf2 and gp91phox were measured in byusing real-time qRT-PCR technique. Result The expression levels of gp91phox (P-value < 0.001), cat (P-value < 0.05), sod1 (P-value < 0.001), nrf2 (P-value < 0.001) were significantly increased compared to control group. Following treatment with Aza, the decreased expression levels of gp91phox (P-value < 0.05), cat (P-value < 0.05), sod1(P-value < 0.001) and nrf2 (P-value < 0.001) were observed in CD patients. Conclusion Overall, our results showed that prescription of Azathioprine can lead to the altered expression of redox system-related genes in patients with CD.

Abstract
INTRODUCTION For the best management of the zygomycosis in immunocompromised patients, the present study aims to detect and identify the etiologic agents by DNA sequencing method and their related factors in clinical samples of patients. METHODOLOGY Clinical samples from 1,058 patients admitted in 11 university hospitals in Shiraz, Southern Iran were collected between July 2015 and July 2018. All samples (bronchoalveolar lavage, sputum, blood, tissue) were examined by routine microscopic and culture tests for zygomycetes. The etiologic agents were identified by the molecular method and sequencing. RESULTS Direct microscopic examinations or pathology smear, culture, and PCR were positive in 61 (5.8%), 15 (1.4%), and 103 (9.7%) patients, respectively. According to EORTC/MSG criteria, the rates of proven, probable, and possible zygomycosis were 59.2% (61/103), 14.6% (15/103), and 26.2% (27/103 patients), respectively. The most prevalent etiologic agents according to sequencing were Rhizopus oryzae (44 cases), Rhizopus microsporus (31 cases), Rhizopus stolonifer (15 cases). Twenty-two patients (21.4%) with positive PCR died. There were significant relations between zygomycosis and the underlying disease (p = 0.043) and prior antifungal therapy (p = 0.023). White blood cell count was in the normal range in 14.1% of patients, and the means of erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) were 65 mm/hour and 57 mg/L, respectively. CONCLUSIONS Molecular methods and sequencing may have considered as suitable tools to diagnose zygomycosis. Identification of the etiologic agents may be considered as the future antifungal therapy and management of the respective patients.

Abstract
Despite several different measures of efficiency that are applicable to the photosynthetic systems, a precise degree of efficiency of these systems is not completely determined. Introducing an efficient model for the dynamics of light-harvesting complexes in biological environments is a major purpose in investigating such systems. Here, we investigate the effect of macroscopic quantum behavior of a system of two pigments on the transport phenomena in this system model which interacts with an oscillating environment. We use the second-order perturbation theory to calculate the time-dependent population of excitonic states of a two-dimensional Hamiltonian using a non-master equation approach. Our results demonstrate that the quantum efficiency is robust with respect to the macroscopicity parameter h˜ solely, but the ratio of macroscopicity over the pigment-pigment interaction energy can be considered as a parameter that may control the energy transfer efficiency at a given time. So, the dynamical behavior and the quantum efficiency of the supposed photosynthetic system may be influenced by a change in the macroscopic behavior of the system.

Abstract
Delayed onset muscle soreness (DOMS) appears after unaccustomed exercise and peaks 24-48 h after exercise. Vitamin D micronutrient and vibration therapy may have an effect on DOMS. The present study investigated the effects of vitamin D micronutrient and vibration therapy on DOMS. Sixty female students were randomly assigned to one of the four groups (n=15 in each group): vitamin D, vibration therapy, vitamin D + vibration therapy, and control. The participants of vitamin D groups received vitamin D (3,800 IU, 1 session daily for 7 days), while the participants of the control groups received placebo. The participants of vibration therapy groups received vibration therapy (50 Hz; 3 sets of 1 min, 1 session daily for 7 days). One day later, the participants performed eccentric exercise (a quadriceps leg extension exercise). Immediately after this exercise protocol, the participants received vitamin D or vibration therapy on basis of their groups. Pain perception, creatine kinase (CK), interleukin (IL)-6, superoxide dismutase and malondialdehyde (MDA) concentration were measured at baseline (before 7 days of intervention), after 7 days of intervention (before eccentric exercise) and 24, 48 and 72 h after eccentric exercise. Statistical analysis was employed and P≤0.05 was considered as the significant level. CK and IL-6 concentrations, as well as pain perception, were significantly lower in the vibration therapy and vitamin D groups compared to the control group 24 to 48 h after eccentric exercise. MDA concentration was significantly lower in the vibration therapy and vitamin D groups compared to the control group 48 to 72 h after eccentric exercise. In conclusion, the present study suggests that vibration therapy and vitamin D supplement may have effects against eccentric exercise-induced delayed onset muscle soreness in female students.

Abstract
Background Surveillance of current changes in the epidemiology of Invasive Fungal Diseases (IFDs) as an important component of the antifungal stewardship programs (ASP), requires careful regular monitoring, especially in high-risk settings such as oncology centers. This study aimed to examine Candida colonization status and corresponding current changes in children with malignancy during repeated admissions and also investigate the possible epidemiological shifts after the implementation of ASP. Methods In this prospective observational study, all eligible patients younger than 18 years were recruited during 2016–2017 at Amir Medical Oncology Center (AMOC) in Shiraz, Iran. Totally, 136 patients were enrolled and 482 samples were collected from different sites (oral/nasal discharges, urine and stool). Weekly regular sampling was carried out during hospitalization. Candida colonization status and epidemiological changes were monitored during repeated admissions. Samples were cultivated on Sabouraud Dextrose agar medium and identified by Polymerase Chain Reaction -Restriction Fragment Length Polymorphism (PCR-RFLP). Results Estimated Candida colonization incidence was 59.9% (82/136) in our patients. Candida colonization was found to be higher in oral cavity and rectum than that in nasal cavity. Among those long-term follow ups and repetitive hospitalizations, a significant number of patients exhibited changes in their colonization patterns (37.7%). Candida colonization did not reveal any significant relationship with age, sex, oncologic diseases and degree of neutropenia. C. albicans (72.0%) was found as the most common Candida species in colonized patients, followed by C. krusei, C. kefyr, C. glabrata and C. parapsilosis. Conclusion Given the high incidence of Candida infections in children with cancers, close monitoring of epidemiologic changes is essential for judicious management, based on local surveillance data and improvement of overall quality of care in high risk patients.

Abstract
The role of quantum tunneling in altering the structure of nucleotides to each other and causing a mutational event in DNA has been a topic of debate for years. Here, we introduce a new quantum mechanical approach for analyzing a typical point-mutation in DNA strands. Assuming each codon as a base state, a superposition of codon states could provide a physical description for a set of codons encoding the same amino acid and there are transition amplitudes between them. We choose the amino acids Phe and Ile as our understudy bio-systems which are encoded by two and three codons, respectively. We treat them as large quantum systems and use double- and triple-well potential models to study the fundamental behaviors of them in interaction with a harmonic environment. We use the perturbation theory to calculate the transition probabilities between the codons which encoding the same amino acid and determine the transition rates of some point mutations. Moreover, we evaluate the quantum biological channel capacity for these transitions to show that the channel capacity depends on the system-environment interaction via the dissipation factor Γ. The obtained results demonstrate that the tunneling rate is under the control of capacity of the corresponding biological channel. In other words, the reduction in quantum channel capacity prevents the quantum tunneling rate to be increased.

Abstract
Background and Purpose: Oral candidiasis is one of the most common fungal infections in humans. The treatment and prophylaxis of the patients suffering from this infection require the identification of new anti-Candida agents with no side effects or toxicity like medicinal plants. The present study was conducted to compare the antifungal activities of the aqueous, ethanolic, and methanolic extracts of the bark and roots of P. granatum with those of two routine antifungal agents (i.e., fluconazole and nystatin) on oral Candida strains isolated from liver transplant recipients. Materials and Methods: Minimum inhibitory concentrations (MICs) of the ethanolic, methanolic, and aqueous extracts of the bark and root of Punica granatum against C. albicans and C. glabrata isolated from oral cavities were evaluated according to the CLSI M27-A3. All data were analyzed in SPSS (version 16.0) by pairwise comparison and Kruskal-Wallis test. Results: The MIC50 and MIC90 values for the methanolic and ethanolic extracts of the bark and root of P. granatum against C. albicans were both obtained as 0.05 mg/ml with the geometric mean (GM) of 0.07. Furthermore, the MIC90 values for the aqueous extracts of bark and root were estimated as 0.05 and 0.2 mg/ml, respectively. With regard to C. glabrata, the MIC50 and MIC90 values for the methanolic and ethanolic extracts of the bark and root were 0.05 mg/ml. However, the MIC90 value for the aqueous extract against this species was obtained as 25 mg/ml. The GM values for the aqueous extracts of the bark and root were 9.49 and 0.32, respectively. Conclusion: As the findings indicated, the methanolic and ethanolic extracts of the bark and root of Punica granatum had anti-Candida activities. Therefore, they can be considered as mouthwash or toothpaste to prevent and treat Candida infections in the oral cavity.

Abstract
INTRODUCTION It is a long time that natural toxin research is conducted to unlock the medical potential of toxins. Although venoms-toxins cause pathophysiological conditions, they may be effective to treat several diseases. Since toxins including scorpion toxins target voltage-gated ion channels, they may have profound effects on excitable cells. Therefore, elucidating the cellular and electrophysiological impacts of toxins, particularly scorpion toxins would be helpful in future drug development opportunities. METHODS Intracellular recording was made from F1 cells of Helix aspersa in the presence of calcium Ringer solution in which Na+ and K+ channels were blocked. Then, the modulation of channel function in the presence of extracellular application of F4 and F6 toxins and kaliotoxin (KTX; 50 nM and 1 μM) was examined by assessing the electrophysiological characteristics of calcium spikes. RESULTS The two active toxin fractions, similar to KTX, a known Ca2+-activated K+ channel blocker, reduced the amplitude of AHP, enhanced the firing frequency of calcium spikes and broadened the duration of Ca2+ spikes. Therefore, it might be inferred that these two new fractions induce neuronal hyperexcitability possibly, in part, by blocking calcium-activated potassium channel current. However, this supposition requires further investigation using voltage clamping technique. CONCLUSION These toxin fractions may act as blocker of calcium-activated potassium channels.

Abstract
Epilepsy is a chronic neurological disease which disrupts the neuronal electrical activity. One-third of patients are resistant to treatment with available antiepileptic agents. The use of herbal medicine for treating several diseases including epilepsy is on the rise. Therefore, further investigation is required to verify the safety and effectiveness of Phytomedicine in treating diseases. The current study is an attempt to elucidate the electrophysiological mechanism of the effect of Dorema ammoniacum gum on a cellular model of epilepsy, using intracellular recording method. The gum was applied either after or before pentylenetetrazole, as an epileptic drug, in order to explore the possible therapeutic and preventive effects of gum. Treatment with D. ammoniacum gum alone increased the neuronal excitability and when applied before or after treatment with PTZ not only did not prevent or change the electrophysiological changes induced by PTZ but also re-enhanced the induction of hyperexcitability and epileptiform activity through depolarizing membrane potential, increasing the firing frequency and decreasing the AHP amplitude. However, phenobarbital, as a standard anti-epileptic agent, almost reversed the effect of PTZ and preserved the normal firing properties of F1 neurons. The possible candidate mechanism of the effect of gum on neuronal excitability could be suppressive effects of gum on voltage and/or Ca2+ dependent K+ channels currents underlying AHP.

Abstract
BACKGROUND Neuropathic pain triggered by peripheral nerve lesion is extremely difficult to manage with current approaches, hence the importance of exploring therapeutic alternatives. METHODS We have analysed adipose-derived mesenchymal stem cells (AD-MSCs) and fibroblast growth factor 1 gene-transfected adipose-derived mesenchymal stem cells (AD-MSCs FGF1 ) on chronic constriction injury (CCI). The mechanical and thermal hypersensitivity were assessed using the von Frey filament, radiant heat and acetone drop tests. Histopathological and apoptotic changes and the level of FGF1, GFAP and TNFα proteins were assessed in the lumbar portion (L4-L6). Moreover, AD-MSCs FGF1 were labelled with 99m Tc -HMPAO and isolated organ counting were performed upon AD-MSCs FGF1 administration. RESULTS Administration of AD-MSCs FGF1 attenuated the CCI-induced mechanical and thermal hypersensitivity. Spinal structural alterations and apoptosis were decreased in the AD-MSCs FGF1 group. The injection of either phosphate-buffered saline or normal NIH3T3 fibroblasts could not attenuate the behavioural symptoms of neuropathic pain. Increased genetically engineered cells were counted in the injured sciatic nerve and the elevated levels of FGF1 were detected in the spinal tissue. Stem cell therapy lead to decrement the level of the CCI-induced TNF-α and GFAP expression. CONCLUSION The intravenous administration of AD-MSCs FGF1 could be considered as a potential remedy for the management of neuropathic pain. SIGNIFICANCE AD-MSCs FGF1 attenuated the CCI-induced mechanical and thermal hypersensitivity. Spinal structural alterations and apoptosis were significantly decreased in the AD-MSCs FGF1 group. Elevated levels of FGF1 were detected in the spinal tissue.

Abstract
Depressive symptom is the most frequent psychological problem reported among chronic kidney disease (CKD) patients being treated by hemodialysis. This article evaluates the effectiveness of multidisciplinary rehabilitation on depressive symptoms in hemodialysis patients and clarifies the role of nurses. This quasi-experimental study was done on 30 patients in the hemodialysis center (educational hospital) in 2013. Eight rehabilitation plans were conducted by nurses. Beck Depression Inventory (BDI) was used before and after intervention. Our data were analyzed using descriptive and inferential statistics. Result of this study shows that there was a significant difference between mean depressive symptom score before (36.4 ± 10.9) and after (10.5 ± 3.1) rehabilitation ( p < .001). It is recommended that rehabilitation program be implemented in all hemodialysis centers with the participation of specialists in different fields.

Abstract
We employ laser induced fluorescence (LIF) spectroscopy to discriminate between normal and cancerous human breast (in-vitro) tissues. LIF signals are usually enhanced by the exogenous agents such as Rhodamine 6G (Rd6G) and Coumarin 7 (C7). Although we observe fluorescence emissions in both fluorophores, Rd6G-stained tissues give notable spectral red shift in practice. The latter is a function of dye concentration embedded in tissues. We find that such red shifts have a strong dependence on the dye concentration in bare, in stained healthy, and in malignant breast tissues, signifying variations in tubular abundances. In fact, the heterogeneity of cancerous tissues is more prominent mainly due to their notable tubular densities- which can provide numerous micro-cavities to house more dye molecules. We show that this can be used to discriminate between the healthy and unhealthy specimens in different biological scaffolds of ordered (healthy) and disordered (cancerous) tissues. It is demonstrated that the quenching process of fluorophore' molecules slows down in the neoplastic tumors according to the micro-partitioning, too.
