    Introduction: The aim of this study was to assess the effectiveness of filling removal material from the apical third of curved mesial root canals of mandibular molars. Reciprocating instrumentation followed by additional rotary instrumentation with instruments made of alloys with different heat treatments was evaluated. Materials and Methods: Thirty-six mesial roots of mandibular molars were divided into two groups: Group Class IV consisted of 16 roots with two independent canals, and Group Class II consisted of 20 roots with two canals that merged into one at their apical level. Each of these two groups were further divided into two subgroups, according to the additional rotary instrument used after the reciprocating instrumentation: Group RH and Group RM for Hyflex and Mtwo, respectively. After each procedural step, the roots were scanned by micro-tomography. After each step of filling removal, the Wilcoxon matched pair test and the Mann-Whitney test were used for the evaluation between groups. The significance level adopted was 5%. Results: Significant differences were observed between groups with different Class II and Class IV anatomies, regarding filling removal after Reciproc (P<0.05). After the use of an additional rotary instrumentation, no differences were observed between the two groups (P>0.05). Conclusions: In the apical third of mesial roots of mandibular molars with Class II anatomy, an additional rotary instrumentation was shown to be necessary for improving the removal of filling material after using the single-file reciprocating instrumentation technique

    Abstract Background and Objective: Black grass jelly served in sweet syrup is one of the Chinese and East and Southeast Asian traditional beverages. An innovative enrichment can make it a better functional food. This study innovatively enriched the black-jelly food with formulas of probiotic Lactobacillus plantarum Mar8, honey, D-allulose and mangosteen pericarp extract. The probiotic viability, antioxidant and hypoglycemic potential were investigated as well. Material and Methods: Ready-to-drink functional beverages included mangosteen pericarp extract varied in concentrations of 0.1, 0.2 and 0.4 mg ml-1, D-allulose in honey and encapsulated probiotic Lactobacillus plantarum Mar8 in black grass jelly containing konjac and carrageenan. The probiotic viability, antioxidant activity and hypoglycemic potential were the selective parameters for the functional beverage formulas. The viability of probiotic Lactobacillus plantarum Mar8 was assessed using total plate count method. Antioxidant activity was assessed based on the reaction of 2,2-Diphenyl-1-picrylhydrazyl radical scavenging. Hypoglycemic potential was investigated by counting petite yeast cells after treating with black grass jelly formulas. Significant differences were reported using one-way analysis of variance and Duncan's test. Statistically significance included p-values≤0.05. Results and Conclusion: The probiotic Lactobacillus plantarum Mar8 encapsulated in black grass jelly survived well in the honey, D-allulose and mangosteen pericarp extract formulated beverages. Honey supported the probiotic viability better, producing further antioxidants and high potentials in hypoglycemia than that those of other formulas did. Mangosteen pericarp extract enriched the functionality of the black grass jelly probiotic beverages. However, further studies are needed to assess favorability and stability of this functional food.

    Background: This descriptive study aimed to assess preoperative pulmonary function test (PFT) results and pulse oximetry readings in patients recovered from COVID-19 who were candidates for elective surgery.Materials and Methods: This is a descriptive study. A total of 110 patients (men = 51) with a mean age of 52.6 years were enrolled in the study. The study protocol was presented to the ethics committee and received approval. Participants included patients with a positive SARS-CoV-2 PCR test history, with a recovery period of at least 6-8 weeks for symptomatic patients and four weeks for asymptomatic patients. Data collection involved a random selection, obtaining informed consent, and conducting a history and physical examination. Pulmonary function capacity and oxygen saturation were assessed, and frailty was evaluated using the Edmonton Frail Scale. Echocardiography and electrocardiography were performed on all patients.Results: The study participants mainly underwent trans-ureteral lithotripsy (TUL), laparoscopic cholecystectomy (LC), and percutaneous nephrolithotomy (PCNL). Symptomatic patients exhibited lower pulse oximetry readings than asymptomatic patients (91.18% vs. 96.13%, p-value = 0.005). Although the average ejection fraction was slightly lower in symptomatic patients (44.25%) compared to asymptomatic patients (48.18%), the difference was insignificant. Symptomatic patients also had higher rates of abnormalities in chest X-rays, electrocardiograms, pulmonary function tests, and fasting blood sugar levels, as well as a higher rate of ICU admission.Conclusion: Comprehensive preoperative evaluations, including pulmonary function and oxygenation assessment, are crucial for COVID-19 survivors undergoing elective surgery. Symptomatic patients showed lower pulse oximetry readings and higher respiratory and cardiovascular abnormalities rates. These findings emphasize the importance of optimizing perioperative management and minimizing complications by thoroughly assessing patients' preoperative health status

    Objectives Autism Spectrum Disorder (ASD) encompasses a range of neurodevelopmental disorders, and early detection is crucial. This study aims to identify the Regions of Interest (ROIs) with significant differences between healthy controls and individuals with autism, as well as evaluate the agreement between FreeSurfer 6 (FS6) and Computational Anatomy Toolbox (CAT12) methods.Materials & MethodsISurface-based and volume-based features were extracted from FS software and CAT12 toolbox for Statistical Parametric Mapping (SPM) software to estimate ROI-wise biomarkers. These biomarkers were compared between 18 males Typically Developing Controls (TDCs) and 40 male subjects with ASD to assess group differences for each method. Finally, agreement and regression analyses were performed between the two methods for TDCs and ASD groups.ResultsBoth methods revealed ROIs with significant differences for each parameter. The Analysis of Covariance (ANCOVA) showed that both TDCs and ASD groups indicated a significant relationship between the two methods (p<0.001). The R2 values for TDCs and ASDgroups were 0.692 and 0.680, respectively, demonstrating a moderatecorrelation between CAT12 and FS6. Bland-Altman graphs showed a moderate level of agreement between the two methods. ConclusionThe moderate correlation and agreement between CAT12 and FS6 suggest that while some consistency is observed in the results, CAT12 is not a superior substitute for FS6 software. Further research is needed to identify a potential replacement for this method

    Abstract Nowadays, an estimated 15% of couples are having trouble conceiving. Infertility is not only a reproductive health problem, but also a social problem that affects family and other interpersonal relationships. Infertility involves psychological problems for both partners. There is a correlation between psychological factors and infertility. It seems that the main cause of infertility can be psychological rather than biological factors. Anxiety, depression, stress associated with infertility and antidepressants used in these patient can impact in the treatment of infertility and their outcomes. Persistent fertility problem will have several negative influences on a couple's life and may cause relationship breakdown. Therefore, more research should be conducted on the reasons of infertility as a way to find the factors related to infertility and reduce its impact
