Background: Prenatal and postnatal depression (PND) is associated with adverse outcomes for mother, fetus, andchild. The aim of study was to examine the prevalence and risk factors of prenatal and postnatal depressive symptoms.Materials and Methods: This was a cross-sectional and hospital-based survey of 2305 pregnant women and post-partumwomen (18-48 years) that was registered in the Babol Pregnancy Mental Health Registry (BPMHR) database from June2020 to March 2021. Two questionnaires, including demographics and depression, were analyzed in this study. Also, theEdinburg Postnatal Depression Scale (EPDS) was used to assess the depressive symptoms. Independent t test and theanalysis of variance were used to compare the means. Multiple logistic regressions were used to determine risk factors fordepressive symptoms.Results: According to the EPDS scale, the prevalence of depressive symptoms was 19.8% in the pregnant womangroup in comparison with the postpartum period (11.6%). Risk factors for antenatal depressive symptoms were parity(women with parity ≥ 4 vs. 1 parity, ß=1.808, P=0.020), two groups of gestational age (gestational age ≤12 weeks vs.28 weeks, ß=1.562 P=0.030) as well as (gestational age 21-27 weeks vs. 28 weeks (ß=1.586, P=0.033), and high-riskpregnancy (high-risk vs. low-risk pregnancy, ß=1.457, P=0.003). For postnatal depressive symptoms, none of the factorswere a significant risk.Conclusion: Prenatal and postnatal depressive symptoms should be screened, particularly for women in the first andsecond trimesters, with high parity, and those with a high-risk pregnancy, as recommended by the present study.

Abstract The primary hurdles for small interference RNA (siRNA) in clinical use are targeted and cytosolic delivery. To overcome both challenges, we have established a novel platform based on phage display, called NNJA. In this approach, a lysosomal cathepsin substrate is engineered within the flexible loops of PIII, that is displaying a unique random sequence at its N-terminus. NNJA library selection targeting cell-expressed targets should yield specific peptides localized in the cytoplasm. That is because phage internalization and subsequent localization to lysosome, upon peptide binding to the cell expressed target, will result in cleavage of PIII, rendering phage non-infective. Such phage will be eliminated from the selected pool and only peptide-phage that escapes lysosomes will advance to the next round. Proof of concept studies with the NNJA library demonstrated cytosolic localization of selected peptide-phage and peptide-siRNA, confirmed through confocal microscopy. More importantly, conjugation of siHPRT to monomeric or multimeric NNJA peptides resulted in significant reduction in HPRT mRNA in various cell types without significant cytotoxicity. Sequence similarity and clustering analysis from NGS dataset provide insights into sequence composition facilitating cell penetration. NNJA platform offers a highly efficient peptide discovery engine for targeted delivery of oligonucleotides to cytosol.

The neuron can be referred to as the primary cell of the nervous system, responsible for transmitting messages through electrical signals between neurons or other cells. To comprehend the intricate behavior of neuron performance, a set of differential equations incorporating non-linear functions is necessary. This research introduces a novel method to improve the digital implementation of Wilson and Morris-Lecar neuron models, offering multiple benefits such as decreased hardware needs, enhanced processing speed and accuracy, and reduced implementation expenses. The proposed method simplifies the original model by converting all its differential equations into a single trigonometric function. This transformation greatly reduces computational complexity by eliminating the need for multipliers, resulting in a concise set of mathematical expressions. The digital implementation of this innovative approach can be efficiently achieved using the COordinate Rotation DIgital Computer (CORDIC) algorithm, which avoids the need for complex mathematical operations. To showcase the effectiveness of this approach, the suggested model is synthesized and implemented on a Field-Programmable Gate Array (FPGA) with successful results. The implementation outcomes reveal a significant improvement in operational frequency, approximately 3.28 and 4.68 times (for Wilson and Morris-Lecar, respectively) higher than the original model.

Optimization algorithms are widely used in various fields to find the best solution to a problem by minimizing or maximizing an objective function, subject to certain constraints. This paper introduces the development and application of an innovative optimization algorithm (WOADD) designed to address the challenges posed by constrained optimization problems with dependent data. Unlike traditional algorithms that struggle with data dependencies and valid range constraints, WOADD incorporates a novel normalization process and a dynamic updating mechanism that accurately considers the interdependencies among features. Specifically, it adjusts the search strategy by calculating a scaling parameter to maneuver within feasible regions, ensuring the preservation of data dependencies and adherence to constraints, thus leading to more efficient and precise optimization outcomes. Our extensive experimental analysis, comparing WOADD against other swarm-based optimization methods on a suite of benchmark functions, illustrates its superior performance in terms of faster convergence rates, improved solution quality, and enhanced determinism in outcomes.

Abstract Herein, we report the synthesis of ZnFe2O4@SiO2@L-lysine@SO3H as a green, novel magnetic nanocatalyst, containing the sulfuric acid catalytic sites on the surface of zinc ferrite as the catalytic support. The physical and chemical properties of raw and modified samples (ZnFe2O4@SiO2@L-lysine@SO3H) were characterized by TGA, EDX, PXRD, Map, and FTIR analyses. The prepared nanocatalyst has excellent catalytic activity in synthesizing the oxidation of sulfides to the sulfoxides and Synthesis of pyrazolyl (Bis(pyrazolyl)methane) derivatives under green conditions. This designed nanocatalyst offers several advantages including the use of inexpensive materials and high yield, simple procedure, and commercially available. The synthesized mesoporous nanocatalyst was recovered and reused in five continuous cycles without considerable change in its catalytic activity.

The neuron is sometimes referred to as the “head” or “central” cell of the nervous system since it has the ability to communicate with other neurons or cells via electrical impulses. The hardware realization and simulation of these neurons are critical in neuromorphic engineering. In this paper, we made a device that generates 4 different spiking patterns of the nervous system as a Spike Generator (SG) using a hybrid approximation of the target model called the Piece-Wised Power-2 Based Izhikevich Model (PWP2BIM). This proposed model works in a low-cost state to achieve a correct digital implementation of the Izhikevich model, one of the main neuron models (i.e. decreasing hardware resources and enhancing speed and accuracy). The proposed model successfully reproduces the behavioral traits of the initial neuron model. To verify the results of the mathematical simulation, the proposed model was synthesized and implemented on the Zynq XC7Z010 (3CLG400) reconfigurable board (FPGA). The findings of hardware synthesis and applications of the suggested paradigm demonstrate that certain biological behaviors may be duplicated more effectively and at a significantly lower cost. The suggested model’s frequency can be increased using this technique (implemented on the Zynq board) at least by 3.6 times compared to the original model, and power consumption can be decreased by 28%. High-frequency design of neuronal models with low-cost attributes is required for application-based types of equipment in case of high-speed operations of these components. Thus, using our approach, the desired goals of application-based features are to be fulfilled. In addition, because the suggested model uses fewer hardware resources than the original model, it is feasible to construct a significantly higher number of neurons (approximately 5 times) on a single Zynq board.

Abstract AAA+ proteases degrade intracellular proteins in a highly specific manner. E. coli ClpXP, for example, relies on a C-terminal ssrA tag or other terminal degron sequences to recognize proteins, which are then unfolded by ClpX and subsequently translocated through its axial channel and into the degradation chamber of ClpP for proteolysis. Prior cryo-EM structures reveal that the ssrA tag initially binds to a ClpX conformation in which the axial channel is closed by a pore-2 loop. Here, we show that substrate-free ClpXP has a nearly identical closed-channel conformation. We destabilize this closed-channel conformation by deleting residues from the ClpX pore-2 loop. Strikingly, open-channel ClpXP variants degrade non-native proteins lacking degrons faster than the parental enzymes in vitro but degraded GFP-ssrA more slowly. When expressed in E. coli, these open channel variants behave similarly to the wild-type enzyme in assays of filamentation and phage-Mu plating but resulted in reduced growth phenotypes at elevated temperatures or when cells were exposed to sub-lethal antibiotic concentrations. Thus, channel closure is an important determinant of ClpXP degradation specificity.

Abstract Background Psychological distress (PD) is a significant issue during pregnancy and postpartum, adversely affecting both children and mothers. This study aims to determine PD's prevalence and risk factors in a large Iranian population sample during pregnancy and postpartum. Methods A cross-sectional study was conducted using data from the Babol Pregnancy Mental Health Registry (located in the north of Iran) between June 2020 and March 2021. A total of 2305 women were included, with 1639 during pregnancy and 666 during postpartum. Psychological distress was assessed using the Brief Symptoms Inventory (BSI-18), and data were analyzed using independent t-tests and multiple logistic regressions. Results The prevalence of psychological distress, defined by a cut-off score of BSI ≥ 13, was 19% during pregnancy and 15% during postpartum. Multivariate logistic analysis revealed that high-risk pregnancy was the leading risk factor for psychological distress during the antenatal period (β = 1.776, P

Background: Urinary stress incontinence occurs due to weakness of the urethral sphincter and/or weakness of the pelvic floor muscles. The purpose of this study is to investigate the complications of TOT surgery in the treatment of women with stress urinary February. Methods: This is a cross-sectional study that was conducted on women suffering from stress urinary incontinence who underwent TOT surgery in Rohani and Mehregan Hospitals of Babol between March 2010 and February 2019. In order to record early complications, the medical records available in the clinic were referred to for the examination of patients one week and two months after the operation. The late complications of the operation were also investigated at the time of entering the study. Also, satisfaction with the procedure was scored using a visual scale (score 0 to 100). SPSS version 26 software was used in this study. Also, the significance level is less than 0.05. Results: The study included 59 patients, the majority of whom were housewives (91.5%), had an education level below high school (74.6%), and were menopausal (71.2%). The average age of the participants is 54.92±9.40 years. The most common postoperative complications were Dyspareunia (20.3%), lower urinary symptoms (13.6%), and incontinency (10.2%). Also, the rarest complications were intraoperative injury to the urethra or bladder (1.7%), mild Vaginal erogenous (1.7%), pain at the operation site (3.4%), and need for adjuvant treatment (3.4%). In response to the question of whether you would recommend this surgery to others who have the same problem, 53 people (83.89%) responded positively. The average level of patients' satisfaction with the operation (on a scale of 0 to 100) was 88.64±23.44. According to the T-test, there is a statistically significant relationship between the incidence of postoperative complications and the level of patient satisfaction (P

Background and Aim: Growth differentiation factor 15 (GDF15) is a cytokine with anti-inflammatory effects, which the influences of acute and chronic exercise on it are not clearly known. Therefore, the aim of the present meta-analysis was to determine the effect of the acute and chronic exercise on circulating GDF15. Methods: To extract original articles published in Farsi and English language journals, a comprehensive search was conducted in PubMed, Web of Science, Scopus, Magiran, Noormags and SID databases until December 22, 2022. Two separate meta-analyses were performed to calculate the effect size of standardized mean difference (SMD) and 95% confidence interval for the acute and chronic effects of exercise on GDF15. Results: A total of 18 studies including 551 subjects were included in the meta-analysis. The results showed that acute exercise activity leads to a significant increase in GDF15 [P=0.001, (1.65 to 0.80 CI: 1.23)], while chronic exercise activity had no significant effect on GDF15 [P=0.24, (0.96 to 0.24-CI: 0.35)]. Conclusion: Exercise leads to a transient and short-term increase in GDF15, which may contribute to the beneficial metabolic effects of exercise.

Interference or transfer from language learners’ first language (L1) is one of the significant variables that contributes to the complexity of SLA process and usually persists intensely at the initial stages of L2 acquisition and development. Drawing upon Meriläinen’s (2010) taxonomy of lexical transfer errors, the present study intended to explore Iranian EFL learners’ lexical transfer error caused by word form, word meaning, and word use. To this aim, a corpus of 189 compositions written by 89 male and 100 female students was investigated. The results revealed that females in general had more lexical transfer errors than males, and that a large amount of the errors stemmed from word use (54%) which was followed by word form (36%) and lastly word meaning (10%). The findings of the study suggest that shifting the students’ attention from vocabulary size to vocabulary depth and exposing them to a large number of authentic collocations and prefabricated patterns are advisable activities that might counteract negative lexical transfer.

Background & Aims Breast cancer (BC) is one of the important challenges of the health system due to its impact on marital relationships. This study aims to compare sexual function and sexual distress of women with and without BC. Materials & Methods In this case-control study, 75 women with BC and 75 healthy women from Zanjan, Iran participated. Data were collected using a demographic form, the female sexual distress scale-revised (FSDS-R), and the female sexual function index (FSFI). Data analysis was done in SPSS software, version 20 using the Mann-Whitney test and multivariate analysis of covariance. Results The mean age of patients was 36.49±6.53 years and the mean age of controls was 36±0.72 years. There was no statistically significant difference between the two groups in terms of some demographic variables such as age, educational level of women and their husbands, occupation of women and their husbands, place of residence, and number of children (P>0.05). The mean score of FSFI in all subscales in the patient group was lower than in the control group. This difference was statistically significant only in the dimension of desire (P=0.003). regarding the sexual distress variable, the mean FSDS-R score of healthy women was lower than that of women with breast cancer, but this difference was not statistically significant (P>0.05). Conclusion The difference between women with and without breast cancer is significant only in the desire domain of sexual function. There is no statistically significant difference between the two groups in sexual distress and in other domains of sexual function. The sexual problems of women with BC require consideration and support, and provding counseling in terms of sexual function.

Abstract Background Staff shortage is a long-standing issue in long term care facilities (LTCFs) that worsened with the COVID-19 outbreak. Different states in the US have employed various tools to alleviate this issue in LTCFs. We describe the actions taken by the Commonwealth of Massachusetts to assist LTCFs in addressing the staff shortage issue and their outcomes. Therefore, the main question of this study is how to create a central mechanism to allocate severely limited medical staff to healthcare centers during emergencies. Methods For the Commonwealth of Massachusetts, we developed a mathematical programming model to match severely limited available staff with LTCF demand requests submitted through a designed portal. To find feasible matches and prioritize facility needs, we incorporated restrictions and preferences for both sides. For staff, we considered maximum mileage they are willing to travel, available by date, and short- or long-term work preferences. For LTCFs, we considered their demand quantities for different positions and the level of urgency for their demand. As a secondary goal of this study, by using the feedback entries data received from the LTCFs on their matches, we developed statistical models to determine the most salient features that induced the LTCFs to submit feedback. Results We used the developed portal to complete about 150 matching sessions in 14 months to match staff to LTCFs in Massachusetts. LTCFs provided feedback for 2,542 matches including 2,064 intentions to hire the matched staff during this time. Further analysis indicated that nursing homes and facilities that entered higher levels of demand to the portal were more likely to provide feedback on the matches and facilities that were prioritized in the matching process due to whole facility testing or low staffing levels were less likely to do so. On the staffing side, matches that involved more experienced staff and staff who can work afternoons, evenings, and overnight were more likely to generate feedback from the facility that they were matched to. Conclusion Developing a central matching framework to match medical staff to LTCFs at the time of a public health emergency could be an efficient tool for responding to staffing shortages. Such central approaches that help allocate a severely limited resource efficiently during a public emergency can be developed and used for different resource types, as well as provide crucial demand and supply information in different regions and/or demographics.

Background and Objectives: Salmonella species (spp) are the most prevalent zoonotic pathogens that cause outbreaks of gastroenteritis worldwide. Therefore evaluation of the profile of antibiotic resistance, virulence factors, and plasmid replicon types in these bacteria is necessary to control and prevent the spread of potentially pathogenic and drug-resistant strains. Materials and Methods: This study was performed on 39 Salmonella spp. The antibacterial susceptibility of isolates to various antibiotic agents was determined using disk diffusion test. β-lactamases (bla) including ESBLs, AmpC, MBLs, and virulence genes were detected by PCR methods. Plasmid incompatibility groups among the isolates were identified using PCR-based replicon typing (PBRT). Results: The most prevalent virulent gene was phoP/Q (84.6%). slyA, sopB, and stn were identified in 79.4% (n=31), 69.2% (n=27), and 2.5% (n=1) of the isolates, respectively. The antibiotic susceptibility testing showed that 30.7% of the isolates were ESBL-producing. blaTEM (41%; n=16) was the most frequent β-lactamase gene among the isolates followed by blaNDM-1 (15.4%; n=6), blaDHA (7.7%; n=3), and blaCTX-M (1.5%; n=1). Six different plasmid replicon types, including IncP (n=9; 23%), IncFIC (n=3; 7.70%), IncY (n=3; 7.70%), IncI1-Iγ (n=2; 5.12%), IncFIIAs (n=1; 2.56%), and IncN (n=1; 2.56%) were observed among the isolates. Conclusion: Our study showed the emergence of carbapenem-resistant and blaNDM-1 among Salmonella spp. for the first time in Kerman, Iran. Since Salmonella spp. plays an important role in the transmission of resistance genes in livestock and humans in the food chains, so more stringent control policies are recommended to prevent the circulation of drug-resistant and potentially pathogenic strains from animals to humans.

Abstract Background Urinary tract infection (UTI) is one of the most prevalent infectious diseases with worldwide health threatening. Antimicrobial resistant strains of Escherichia coli (E. coli) are a common cause of UTI which were identified as a treatment challenge. This study aimed to assay the prevalence of common β-lactam resistance genes including bla TEM, bla SHV, bla CTX-M and bla CMY and phenotypic resistance to commonly used β-lactam and fluoroquinolone antibiotics in UTIs. These factors were evaluated in various phylogenetic groups (phylotypes) of E. coli isolates. Real-time PCR was applied to detect β-lactam resistance genes and conventional PCR was used to determine the phylotypes. Phenotypic resistance against β-lactams (ceftazidime, cefotaxime, aztreonam and ceftriaxone) and fluoroquinolones (ciprofloxacin) were identified by the disc diffusion technique. The ability of extended spectrum β-lactamases (ESBLs) production in E. coli isolates was detected using the combined disc diffusion method. Results The prevalence of resistance genes were 89.6% for bla TEM, 44.3% for bla CTX-M, 6.6% for bla SHV and 0.9% for bla CMY. The two high prevalent phylotypes were B2 (29.2%) and D (17.9%) followed by E (14.1%), F (9.4%), C (6.6%) and 10.3% of isolates were unknown in phylotyping. Disc diffusion results showed high prevalence of antibiotic resistance to cefotaxime (88.6%), aztreonam (83%), ceftireaxon (77.3%), ceftazidime (76.4%) and ciprofloxacin (55.6%). Totally, 52.8% of isolates were found as phenotypical ESBL-producers. Conclusions This study’s results confirmed an explosion of antibiotic resistance amongst E. coli isolates from UTI against β-lactams and fluoroquinolones. Findings explain the necessity of deep changes in quantity and quality of drug resistance diagnosis and antibiotic therapy strategies. More studies are suggested to better and confident evaluations.

Background and Objective: Previous cesarean sections are the most common cause of increased cesarean section in many parts of the world, although it is not always necessary. Considering the high statistics of cesarean section in Iran and especially the high rate of repeat cesarean section and creating motivation for vaginal birth after cesarean section, this study was conducted in order to investigate the maternal and neonatal outcomes of vaginal birth after one cesarean section. Methods: This cross-sectional study was conducted on 104 pregnant women with a previous caesarean section and transverse incision on the lower segment in Ayatollah Rouhani Hospital of Babol in two groups; 50 people in the first group who underwent repeat emergency cesarean section and 54 people in the second group who consented to vaginal birth after cesarean section (VBAC). Demographic characteristics and maternal and neonatal complications were investigated and compared between the two groups. Findings: In this study, there were no significant differences between the two groups in terms of demographic characteristics. Infant mortality rate was reported in 6 cases (12%) in the first group and 2 cases (3.7%) in the second group. Furthermore, 3 babies (6%) in the repeat cesarean section group and 9 babies (16.7%) in the vaginal birth group after cesarean section were admitted to the neonatal intensive care unit. The 5-minute Apgar was also significantly higher in the babies of the vaginal birth group after cesarean section (p=0.04). The duration of mother's hospitalization was 3.98±5.53 and 2.11±0.31 days in the repeat cesarean and vaginal birth groups, respectively (p=0.02). Conclusion: According to the results of this study, maternal and neonatal complications did not increase in vaginal birth after cesarean section, and if the mother wishes, vaginal birth can be performed after one cesarean section.

The photocycle of a reversible photoisomerizing rhodopsin mimic (M2) is investigated. This system, based on the cellular retinoic acid binding protein, is structurally different from natural rhodopsin systems, but exhibits a similar isomerization upon light irradiation. More specifically, M2 displays a 15-cis to all-trans conversion of retinal protonated Schiff base (rPSB) and all-trans to 15-cis isomerization of unprotonated Schiff base (rUSB). Here we use hybrid quantum mechanics/molecular mechanics (QM/MM) tools coupled with transient absorption and cryokinetic UV-vis spectroscopies to investigate these isomerization processes. The results suggest that primary rPSB photoisomerization of M2 occurs around the C13═C14 double bond within 2 ps following an aborted-bicycle pedal (ABP) isomerization mechanism similar to natural microbial rhodopsins. The rUSB isomerization is much slower and occurs within 48 ps around the C15═N double bond. Our findings reveal the possibility to engineer naturally occurring mechanistic features into artificial rhodopsins and also constitute a step toward understanding the photoisomerization of UV pigments. We conclude by reinforcing the idea that the presence of the retinal chromophore inside a tight protein cavity is not mandatory to exhibit ABP mechanism.
