Effect of sexual health education on sexual function and satisfaction of menopausal migrant women: an application of the theory of planned behavior.

OBJECTIVES: This study investigated the effect of an intervention based on the theory of planned behavior on sexual function and satisfaction of migrant women during menopause in Iran. METHODS: This quasi-experimental study was conducted on 88 migrant and menopausal women in Iran. Sampling was performed using the multistage methods in four health care centers. The educational program based on the theory of planned behavior was held in 4 sessions of 90 min for 4 weeks in the intervention group. The final evaluation of the intervention was performed immediately, and the follow-up stage (3 months after the intervention) by completing questionnaires in two groups. The data was analyzed with SPSS 20 software with statistical tests of mean and standard deviation, Manwitney, Frideman, Generalized Estimating Equations. RESULTS: The results showed that after the intervention, the mean score of sexual function in the intervention group increased from 16.53 ± 2.68 before to 17.52 ± 2.90 immediately and 17.38 ± 2.81 in follow up stage (p < 0.05). But in the control group, this score was not statistically significant during the study stages (p > 0.05). CONCLUSION: The results indicate that the intervention based on the theory of planned behavior is effective in sexual function and satisfaction with the married life of migrant women during menopause. but to change the sexual function, studies with a longer duration and also the use of other educational models are suggested.

Prevalence of surgical site infection and risk factors in patients after knee surgery: A systematic review and meta-analysis.

The present systematic review and meta-analysis aimed to determine the prevalence of surgical site infection (SSI) and risk factors in patients after knee surgery. A comprehensive and systematic search was carried out across various international electronic databases, including Scopus, PubMed and Web of Science, as well as Persian electronic databases like Iranmedex and the Scientific Information Database (SID). This search involved the utilization of keywords derived from Medical Subject Headings, such as 'Prevalence', 'Surgical wound infection', 'Surgical site infection' and 'Orthopaedics', spanning from the earliest records up to 1 October 2023. To assess the quality of the included studies, the Appraisal tool for Cross-Sectional Studies (AXIS tool) was utilized. The study encompassed a combined participant pool of 11 028 individuals who underwent knee surgery across seven selected studies. The collective prevalence of SSI in patients who underwent knee surgery, as reported in the seven included studies, was determined to be 3.0% (95% CI: 1.2% to 7.5%; I2 = 96.612%; p < 0.001). The combined prevalence of SSI in patients with DM, as reported in six studies, was 5.1% (95% CI: 1.7% to 14.5%; I2 = 79.054%; p < 0.001). Similarly, the pooled prevalence of SSI in patients with HTN, drawn from four studies, was 1.8% (95% CI: 0.7% to 4.5%; I2 = 63.996%; p = 0.040). Additionally, the collective prevalence of SSI in patients with a history of tobacco use, based on findings from six studies, was 4.8% (95% CI: 1.4% to 15.2%; I2 = 93.358%; p < 0.001). Subgroup analysis was conducted within six studies, categorizing them by two countries, namely China and the USA. These analyses revealed that the prevalence of SSI following knee surgery was 3.0% in China and 2.0% in the USA. It is noteworthy that variations in SSI prevalence across different studies may be attributed to a multitude of factors, particularly varying risk factors among patient populations. To address this issue and mitigate the impact of SSI on knee surgery patients, it is advisable to develop tailored interventions.

Antimicrobial resistance and biofilm formation capacity among Acinetobacter baumannii strains isolated from patients with burns and ventilator-associated pneumonia.

BACKGROUND: Acinetobacter baumannii is a pathogen responsible for nosocomial infections, especially in patients with burns and ventilator-associated pneumonia (VAP). The aims of this study was to compare the biofilm formation capacity, antimicrobial resistance patterns and molecular typing based on PFGE (Pulsed-Field Gel Electrophoresis) in A. baumannii isolated from burn and VAP patients. MATERIALS AND METHODS: A total of 50 A. baumannii isolates were obtained from burn and VAP patients. In this study, we assessed antimicrobial susceptibility, biofilm formation capacity, PFGE fingerprinting, and the distribution of biofilm-related genes (csuD, csuE, ptk, ataA, and ompA). RESULTS: Overall, 74% of the strains were multidrug resistant (MDR), and 26% were extensively drug-resistant (XDR). Regarding biofilm formation capacity, 52%, 36%, and 12% of the isolates were strong, moderate, and weak biofilm producers. Strong biofilm formation capacity significantly correlated with XDR phenotype (12/13, 92.3%). All the isolates harbored at least one biofilm-related gene. The most prevalent gene was csuD (98%), followed by ptk (90%), ataA (88%), ompA (86%), and csuE (86%). Harboring all the biofilm-related genes was significantly associated with XDR phenotype. Finally, PFGE clustering revealed 6 clusters, among which cluster No. 2 showed a significant correlation with strong biofilm formation and XDR phenotype. CONCLUSION: Our findings revealed the variable distribution of biofilm-related genes among MDR and XDR A. baumannii isolates from burn and VAP patients. A significant correlation was found between strong biofilm formation capacity and XDR phenotype. Finally, our results suggested that XDR phenotype was predominant among strong-biofilm producer A. baumannii in our region.

Long non-coding RNA/epithelial-mesenchymal transition axis in human cancers: Tumorigenesis, chemoresistance, and radioresistance.

Epithelial-to-mesenchymal transition (EMT) is a process that involves the transformation of polarized epithelial cells to attain a mesenchymal phenotype that presents an elevated migratory potential, invasiveness, and antiapoptotic properties. Many studies have demonstrated that EMT is a prominent event that is associated with embryogenesis, tumor progression, metastasis, and therapeutic resistance. The EMT process is driven by key transcription factors (such as Snail, Twist, ZEB, and TGF-ß) and several long non-coding RNAs (lncRNAs) in many non-pathological as well as pathological conditions. In the present report, we have comprehensively discussed the oncogenic and tumor suppressor role of lncRNAs and their mechanism of action in the regulation of the EMT process in various cancers such as brain tumors, gastrointestinal tumors, and gynecological and urological tumors. We have also elaborated on the role of lncRNAs in the regulation of EMT-related transcription factors (such as Snail, Twist, ZEB, and TGF-ß) and therapeutic response (chemoresistance and radioresistance). Lastly, we have emphasized the role of exosomal lncRNAs in the regulation of EMT, metastasis, and therapeutic response in the aforementioned cancers. Taken together, this review provides a detailed insight into the understanding of role of lncRNAs/exosomal lncRNAs in EMT, metastasis, and therapeutic response in human cancers.

Evaluation of the Iranian panel reactive antibody calculator and potential usefulness: A retrospective study.

BACKGROUND AND OBJECTIVES: There are several cPRA websites based on large enough samples in Eurotransplant, the United Network for Organ Sharing (UNOS), and the Canadian Transplant Registry (CTR). On the other hand, those calculators can differ based on the ethnicity to which they are applied. We developed the Iranian PRA calculator and compared it with UNOS and CTR calculators. METHODS: The allele and haplotype frequencies of the Iranian donor pool were estimated using the HLA typing of 523 deceased Iranian kidney donors. The Organ Procurement and Transplantation Network formula was used to generate cPRA (cPRA frequency). We also used a computer script to compare the undesirable antigens of patients with the human leukocyte antigen (HLA) phenotype of donors (cPRA filtering). A total of 100 anti-HLA antibody profiles were determined in 100 sensitized individuals on the waiting list, and cPRA was estimated using various PRA calculators. RESULTS: Variable allelic frequencies were obtained from population heterogeneity in each calculator's donor panel. However, no significant changes in cPRA were identified between the Iranian calculator, UNOS, and the Canadian online calculators. Lin's concordance correlation coefficient of .98 showed that cPRA (freq) and cPRA (filter) values had almost perfect agreement. INTERPRETATION AND CONCLUSION: The cPRA values from the Iranian calculator are comparable to those from UNOS and CTR calculators. The donor filtering method was more useful because of factors like cost and flexibility. It also makes it easier to update cPRA on a regular basis.

Anti-Inflammatory Activity of Ferula assafoetida Oleo-Gum-Resin (Asafoetida) against TNF-α-Stimulated Human Umbilical Vein Endothelial Cells (HUVECs).

Inflammation is the body's biological reaction to endogenous and exogenous stimuli. Recent studies have demonstrated several anti-inflammatory properties of Ferula species. In this paper, we decided to study the anti-inflammatory effect of ethanolic extract of Ferula assafoetida oleo-gum-resin (asafoetida) against TNF-α-stimulated human umbilical vein endothelial cells (HUVECs). HUVECs were cultured in a flat-bottom plate and then treated with ethanolic extract of asafoetida (EEA, 0-500 µg/ml) and TNF-α (0-100 ng/ml) for 24 h. We used the MTT test to assess cell survival. In addition, the LC-MS analysis was performed to determine the active substances. HUVECs were pretreated with EEA and then induced by TNF-α. Intracellular reactive oxygen species (ROS) and adhesion of peripheral blood mononuclear cells (PBMCs) to HUVECs were evaluated with DCFH-DA and CFSE fluorescent probes, respectively. Gene expression of intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), and E-selectin and surface expression of ICAM-1 protein were measured using real-time PCR and flow cytometry methods, respectively. While TNF-α significantly increased intracellular ROS formation and PBMC adhesion to TNF-α-induced HUVECs, the pretreatment of HUVECs with EEA (125 and 250 µg/ml) significantly reduced the parameters. In addition, EEA pretreatment decreased TNF-α-induced mRNA expression of VCAM-1 and surface protein expression of ICAM-1 in the target cells. Taken together, the results indicated that EEA prevented ROS generation, triggered by TNF-α, and inhibited the expression of VCAM-1 and ICAM-1, leading to reduced PBMC adhesion. These findings suggest that EEA can probably have anti-inflammatory properties.

rs6426881 in the 3'-UTR of PBX1 is involved in breast and gastric cancers via altering the binding potential of miR-522-3p.

BACKGROUND: Breast and gastric cancers are the most important diseases that lead to cancer death and social healthcare challenge. Overexpression of PBX1, a proto-oncogene, is correlated with the progression and metastasis of various cancers. For the first time, in this study the researchers evaluated the relationship between rs6426881, affecting miR-522-3p binding to the PBX1, with breast and gastric cancers. METHODS AND RESULTS: The Microarray analysis was performed for finding the relative expression level of PBX1 and hsa-miR-522-3p, based on high throughput experiments. The GSE54397, GSE112369, GSE10810, GSE241585.ER, GSE24185.PR, GSE68373, and GSE38167 datasets were analyzed. A case-control study was carried out in 123 Iranian suffering from breast cancer and 132 participants as control samples as well as 130 people suffering from gastric cancer and 54 people as control group members. SNP rs6426881 in the 3'-UTR of PBX1 was genotyped by the High-Resolution Melting (HRM) method. Association analysis revealed that rs6426881 is correlated with Estrogen and Progesterone receptors, grade, and stage of breast cancer. Furthermore, a significant relationship was observed between the genotypes and blood groups in gastric cancer, while the distribution of alleles was significantly related to smoking, status of the primary tumor, and metastasis (Chi-Square P < 0.05). Finally, Bioinformatics analyses suggested that rs6426881 contains binding sites for miR-522-3p in the 3'-UTR of PBX1 transcript. The finding suggested that TT genotype is associated with poor prognosis in breast and gastric cancer. CONCLUSIONS: The rs6426881 T allele at PBX1 3'-UT is significantly related to breast and gastric cancers by altering the regulatory affinity of miR-522-3p to PBX1 3'-UTR and may be suggested as a novel prognostic biomarker for the diseases.

A hybrid computational intelligence approach for bioremediation of amoxicillin based on fungus activities from soil resources and aflatoxin B1 controls.

Nowadays, releasing the Emerging Pollutants (EPs) in the nature is one of the main reasons for many health and environmental disasters. Amoxicillin as an antibiotic is one of the EPs and categorized as the Endocrine Disrupting Compounds (EDCs) in hazardous materials. Accumulation of amoxicillin in the soil bulk increases the cancer risk, drug resistances and other epidemiological diseases. Hence, the soil bioremediation of antibiotics can be a solution for this problem which is more environmental-friendly system. This study technically creates a bio-engine setup in soil bulk for remediation of amoxicillin based on Aspergillus Flavus (AF) activities and Removal Percentage (RP) of amoxicillin with Aflatoxin B1 Generation (AG) controls. The main novelty is to propose a hybrid computational intelligence approach to do optimization for mechanical and biological aspects and to predict the behavior of bio-engine's effective mechanical and biological features in an intelligent way. The optimization model is formulated by the Central Composite Design (CCD) which is set by the Response Surface Methodology (RSM). The prediction model is formulated by the Random Forest (RF), Adaptive Neuro Fuzzy Inference System (ANFIS) and Random Tree (RT) algorithms. According to the experimental practices from real soil samples in different times and places, concentration of amoxicillin and Aflatoxin B1 are set equal to 25 mg/L (ppm) and 15 µg/L (ppb). Likewise, the outcomes of experiments in CCD-RSM computations are evaluated by curve fitting comparisons between linear, 2FI, quadratic and cubic polynomial equations with considering to regression coefficient and predicted regression coefficient values, ANOVA and optimization by sequential differentiation. Based on the results of CCD-RSM, the RP performance in the optimum conditions is measured around 86% and in 25 days after runtime, the RP and AG are balanced in the safe mode. The proposed hybrid model achieves the 0.99 accuracy. The applicability of the research is done using real field evaluations from drug industrial park in Mashhad city in Iran. Finally, a broad analysis is done and managerial insights are concluded. The main findings of the present research are: (I) with application of bioremediation from fungus activities, amoxicillin amounts can be control in soil resources with minimum AG, (II) ANFIS model has the best accuracy for smart monitoring of amoxicillin bioremediation in soil environments and (III) based on the statistical assessments Aeration Intensity and AF/Biological Waste ratio are most effective on the amoxicillin removal percentage.

Application of ɑ-Tocotrienol-Loaded Biocompatible Precirol in Attenuation of Doxorubicin Dose-Dependent Behavior in HUH-7 Hepatocarcinoma Cell Line.

Tumor-targeted nanoparticle delivery system has been known as a substitute and capable achievement in cancer treatment compared to conventional methods. In this study, we examined potential application of ɑ-tocotrienol-Precirol formulation to enhance efficiency of doxorubicin (DOX) in induction of apoptosis in HUH-7 hepatocarcinoma cells. ɑ-tocotrienol-loaded nanoparticles were characterized at the point of zeta potential, particle size, scanning electron microscope (SEM), and cell internalization. To evaluate antiproliferative effects of formulation, apoptosis, cell cycle procedure, flow cytometry, and MTT assays were employed. Optimum size of the ɑ-tocotrienol formulation revealed narrow size distribution with mean average of 78 ± 3 nm. IC50 values for ɑ-tocotrienol and ɑ-tocotrienol-nano structured lipid carriers after 24 h were 15 ± 0.6 and 10 ± 0.03 µM, respectively. After incubation of cells with ɑ-tocotrienol-loaded careers, the rate of cell proliferation decreased from 53 ± 6.1 to 34 ± 7.1% (P < 0.05). A significant improvement in the apoptosis percentage was revealed after treatment of the HUH-7 cell line with DOX and ɑ-tocotrienol careers (P < 0.05). Gene expression results demonstrated a marked decrease in survivin and increase in Bid and Bax levels. Our findings suggest that ɑ-tocotrienol-loaded nanoparticles elevate DOX efficacy in HUH-7 hepatocarcinoma cell.

Assisted reproductive technology and the risk of preeclampsia: an updated systematic review and meta-analysis.

BACKGROUND: The objective of this systematic review and meta-analyses was to assess the risk of preeclampsia among women who conceived with assisted reproductive technology (ART). METHODS: We searched the ISI Web of Knowledge, Medline/PubMed, Scopus, and Embase (from inception to May 2017) for English language articles using a list of key words. In addition, reference lists from identified studies and relevant review articles were also searched. Data extraction was performed by two authors, and the study quality was assessed using the Newcastle-Ottawa Scale. Random-effects model meta-analysis was applied to pool the relative risks (RR) across studies. RESULTS: A total of 48 studies (5 case-control studies and 43 cohort studies) were included in this meta-analysis. The Cochran Q test and I2 statistics revealed substantial heterogeneity (Q = 26,313.92, d.f. = 47, p < 0.001 and I2 = 99.8%). Meta-analysis showed a significant increase in preeclampsia in women who conceived by ART compared with those who conceived spontaneously (RR = 1.71, 95% CI = 1.11-2.62, p = 0.015). CONCLUSIONS: The findings of this systematic review indicate that the use of ART treatment is associated with a 1.71-fold increase in preeclampsia.

Little information about fertility preservation is provided for cancer patients: A survey of oncologists' knowledge, attitude and current practice.

The objective of this survey was to explore the knowledge, attitude and current practice of Iranian oncologists about fertility preservation (FP) services provided to cancer patients. Oncologists who completed this survey were a convenience sample of 103 specialists in radiation oncology and haematology who attended large national and international congresses and symposia across Iran. A 23-item self-administered questionnaire included questions on knowledge, attitudes and practice. The most well known of the FP methods among Iranian oncologists were gonadotropin-releasing hormone therapy and sperm cryopreservation, with scores of 2.77 (1.10) and 2.64 (1.00) respectively. These scores were above the median value of 2.5 on a 4-point Likert scale, in contrast to a mean knowledge score across all the FP options of 2.25 (0.71). With regard to attitudes, age was the most important reason for discussing FP with patients, mean score 3.75 (0.54), while heredity was the least important, mean score 2.98 (0.87). In terms of practice, most oncologists did not provide their patients with written information about FP. However, 74 (72.5%) said they referred cancer patients on to reproductive specialists. This sample of Iranian oncologists would benefit from more information on FP methods and prevent loss of fertility among cancer patients.

TRFBA: an algorithm to integrate genome-scale metabolic and transcriptional regulatory networks with incorporation of expression data.

Motivation: Integration of different biological networks and data-types has been a major challenge in systems biology. The present study introduces the transcriptional regulated flux balance analysis (TRFBA) algorithm that integrates transcriptional regulatory and metabolic models using a set of expression data for various perturbations. Results: TRFBA considers the expression levels of genes as a new continuous variable and introduces two new linear constraints. The first constraint limits the rate of reaction(s) supported by a metabolic gene using a constant parameter (C) that converts the expression levels to the upper bounds of the reactions. Considering the concept of constraint-based modeling, the second set of constraints correlates the expression level of each target gene with that of its regulating genes. A set of constraints and binary variables was also added to prevent the second set of constraints from overlapping. TRFBA was implemented on Escherichia coli and Saccharomyces cerevisiae models to estimate growth rates under various environmental and genetic perturbations. The error sensitivity to the algorithm parameter was evaluated to find the best value of C. The results indicate a significant improvement in the quantitative prediction of growth in comparison with previously presented algorithms. The robustness of the algorithm to change in the expression data and the regulatory network was tested to evaluate the effect of noisy and incomplete data. Furthermore, the use of added constraints for perturbations without their gene expression profile demonstrates that these constraints can be applied to improve the growth prediction of FBA. Availability and Implementation: TRFBA is implemented in Matlab software and requires COBRA toolbox. Source code is freely available at http://sbme.modares.ac.ir .

Glutathione decorated gold-magnetic nanoparticles: efficient and recyclable catalyst for biotechnological and pharmaceutical applications.

Nowadays, since the core-shell gold-magnetite nanoparticles include the saturation magnetisation (iron oxide) and plasmon surface (gold shell) properties, they have been considered in biological and biomedicine research areas. In the present work, multifunctional glutathione decorated gold-coated iron oxide nanoparticles (GSH-AuMNPs) were successfully synthesised and fully characterised. From the absorption peak at 525, the formation of the core-shell GSH-AuMNPs was confirmed. Although the saturation magnetisation value was slightly decreased during the formation process, they were easily recovered through magnetic decantation. The biocompatibility of the synthesised NPs was approved by the cytotoxicity researches. Furthermore, the GSH-AuMNPs indicated a good catalytic activity for the catalytic reduction of 2-nitrophenol by sodium borohydride and reused for six consecutive cycles without a significant decrease in its activity. Overall, this study introduced a unique structure with high catalytic activity, which could provide a useful platform for the biomedical, analytical, catalytic applications and wastewater treatment.

Nutritional intake and its association with educational achievement in high-school students in Islamic Republic of Iran.

BACKGROUND: Inadequate food intake can affect learning and memory. Studies on the nutrient intake of adolescents in Sabzevar are lacking. AIMS: This study assessed the nutrient intake of high-school students in Sabzevar and its association with academic attainment. METHODS: This cross-sectional study was conducted on 800 of 8 000 high-school students in Sabzevar. Stratified sampling was used. Demographic data and academic information were collected and the parents of the students completed a food frequency questionnaire which included 189 food items. The students' weight and height were measured using standard methods. Each food was coded using Nutritionist IV software and mean values of nutrients (13 vitamins/minerals, 4 food types and total energy) were calculated. RESULTS: The mean body mass index of female and male students was 20. 3 (SD 2.7) kg/m2 and 19.5 (SD 3.2) kg/m2 respectively. The intakes of energy, vitamins A, C, D, folic acid, calcium, iron and zinc were significantly lower than the dietary reference intake (P < 0.05). A statistically significant correlation was seen between iron intake and academic scores in female students (P < 0.05) but not for any other nutrient. CONCLUSIONS: The intake of most nutrients in high-school students in Sabzevar was lower than the dietary reference intake. Nutrition education and nutritional support strategies are recommended to improve the nutritional status of these students.

Vitamin D-Loaded Nanostructured Lipid Carrier (NLC): A New Strategy for Enhancing Efficacy of Doxorubicin in Breast Cancer Treatment.

The dangerous dose-dependent side effects of anticancer agents triggered the finding of new approaches for elevated chemotherapy efficacy. This study investigated the potential application of nanostructured lipid careers (NLCs) in increasing vitamin D3 (VitD) effectiveness in breast cancer cell (MCF-7) in concurrent administration with doxorubicin (Dox). VitD-loaded NLCs were characterized by particle size, zeta potential, Fourier transform infrared spectroscopy, and scanning electron microscope. Cytotoxicity and molecular effects of formulation were evaluated by MTT, DAPI staining, flow cytometry, and real-time quantitative PCR assays. The formulation revealed mean particle size of 87±5 nm with a polydispersity index of 0.24 confirmed by SEM images. The IC50 values for VitD and Dox were 1.3 ± 0.04 and 0.65 ± 0.05 µM, respectively. VitD-loaded NLCs decreased the percentage of cell proliferation from 49 ± 7.2% to 37 ± 5.1% (P < 0.05). Cotreatment of the cells with VitD-loaded NLCs and Dox caused over a twofold increase in the percentage of apoptosis (P < 0.05). Gene expression profile demonstrated a significant decrease in antiapoptotic factor survivin along with increase in proapoptotic factor Bax mRNA levels. Overall, our results introduced the NLC technology as a novel strategy to elevate the efficacy of chemotherapeutics in breast cancer.

Association of Serum hs-CRP Levels With the Presence of Obesity, Diabetes Mellitus, and Other Cardiovascular Risk Factors.

BACKGROUND: Diabetes mellitus remains one of the major health problems of the 21st century and is associated with comorbidities including obesity and metabolic abnormalities. The study was conducted to evaluate serum high-sensitivity C-reactive protein (hs-CRP) levels, as a marker of inflammation, in a large sample of Iranian population without a history of cardiovascular or inflammatory disease and cancer, and to relate this to fasting blood glucose (FBG) and the presence of diabetes mellitus. METHODS: The study consisted of 7,762 subjects divided into four groups-nonobese/nondiabetic, obese/nondiabetic, nonobese/diabetic and obese/diabetic-based on the BMI classification and their FBG. Anthropometric characteristics were measured and blood was collected for the evaluation of fasted lipid profile, FBG and serum hs-CRP levels. RESULTS: Several clinical and biochemical characteristics were significantly different among the four groups: FBG, P < 0.001; total cholesterol (TC), P < 0.001; and triglyceride (TG), P < 0.001. The subjects with a serum hs-CRP >3 mg/dl had higher TC (P < 0.001), low-density lipoprotein cholesterol (LDL-C, P < 0.001), TG (P < 0.001), fat percentage (P < 0.001), and systolic and diastolic blood pressure (P < 0.001) compared with subjects with a serum hs-CRP <3 mg/dl. Multivariate analysis showed FBG, LDL-C, and waist circumference (WC) associated with increased serum hs-CRP levels (P < 0.001). CONCLUSIONS: FBG, LDL-C, WC and gender are independently associated with serum hs-CRP concentrations.

Accessory Spleen in the Splenic Hilum: a Cadaveric Study with Clinical Significance.

AIM: An accessory spleen is an additional tissue of the spleen that may be found near the spleen. It is a congenital anomaly of the spleen that its incidence has been reported 10-30% of the population. Hence, the objective of this study was evaluation the incidence of accessory spleen in Iranian cadavers. METHOD: Sixty hundred and ninety three spleens (541 males, 152 females) were excised from cadavers in the dissection hall of Mashhad Forensic Medicine Organization cadavers. Inclusion criteria were as follows: Fresh Iranian cadavers with no history of alcohol, poisoning or drug abuse, and no evidence of pathologic abnormality or injury to the spleen. The presence of accessory spleens, its dimension and weight investigated in cadavers. RESULTS: During routine postmortem examination, five cases with an accessory spleen were found in the autopsy laboratory of Mashhad legal Medicine Organization between June 2014 and July 2015. Of the cases, 3 were male and 2 were female. The accessory spleens were observed at the splenic hilum. The length of the accessory spleens ranged from 2-3.5 cm, while the range of width was between 0.5 and 2.5 cm. The accessory spleens were confirmed by histological examination. CONCLUSION: An accessory spleen has clinical importance in some locations. When an accessory spleen is situated in another site, it may mimic some tumors such as pancreatic tumor and adrenal tumor. In addition, accessory spleen may cause hyperplasia after splenectomy and be responsible for a recurrence of the hematological disorders.

A Proposal of a Design for the Bionic Hand: Describing the Integration, Motor Controlling System, Stereognosis, and Proprioception Sensory Feedback Components.

Despite recent advancements in bionic upper limb prostheses technology, the rejection rate by users remains unacceptably high. Various factors contribute to this issue, such as limited functionality, complex control mechanisms, and discomfort, with most of these concerns being documented solely through self-assessment surveys. In this article, we introduce our proposed four components for an integrated bionic hand aimed at making it closely resemble a natural hand. These components include an integrated intramedullary stem, a kineticomyographic motor control system, sensory feedback for stereognosis, and sensory feedback for proprioception.

Performance of magnetic nanocomposite based on xanthan gum-grafted-poly(acrylamide) crosslinked by borax for the effective elimination of amoxicillin from aquatic environments.

This study evaluated the effectiveness of using nanocomposite (NCs) of xanthan gum grafted polyacrylamide crosslinked Borax - iron oxide nanoparticle (XG-g-pAAm-CL-Borax-IONP) to remove the amoxicillin antibiotic (AMX) from an aquatic environment. To confirm the structural characteristics of the prepared XG-g-pAAm-CL-Borax-IONP NCs, unique characterization methods (XRD, FT-IR, FE-SEM, EDX, BET, TGA, Zeta, and VSM) were used. Adsorption experimental setups were performed with the influence of solution pH (4-9), the effect of adsorbent dose (0.003-0.02 g), the effect of contact time (5-45 min), and the effect of initial AMX concentration (50-400 mg/L) to achieve the most efficient adsorption conditions. Based on the Freundlich isotherm model, XG-g-pAAm-CL-Borax-IONP NCs provided the maximum AMX adsorption capacity of 1183.639 mg/g. This research on adsorption kinetics also established that the pseudo-second-order model (R2 = 0.991) is outstanding compatibility with the experimental results. AMX adsorption on the NCs may occur through intermolecular hydrogen bonding, diffusion, and trapping into the polymer network. Even after five cycles, these NCs still displayed the best performance. Based on these results, XG-g-pAAm-CL-Borax-IONP NCs may be a viable material for the purification of AMX from contaminated water.
