    Background: Any deviation in the normal spinal alignment can alter the cardiorespiratory endurance and the posture control. The aim of present study was to investigate the correlation between cardiorespiratory endurance, dynamic postural control and kyphosis angle among the students. Materials and Methods: This cross-sectional study was carried out on students (n=100; 48 girls and 52 boys) selected randomly according to inclusion criteria. Cardiorespiratory endurance, postural control and kyphosis angle were assessed using shuttle run test, Y balance test and flexible ruler, respectively. Normal distribution of the data was assessed using the Kolmogorov–Smirnov test. Data were analyzed using Pearson correlation product moment and linear regression (P≤0.05). Results: The results showed a significant negative correlation between the cardiorespiratory endurance and kyphosis angle (P=0.012, r=-0.3.3). In addition, a significant negative correlation was observed between the dynamic postural control and kyphosis angle (P=0.003, r=-0.254). Conclusion: According to our findings it seems mandatory for health and school's, sport coaches to screen the student's spinal deformities and evaluate its associated complications (e.g. decreased cardiorespiratory endurance and postural balance)

    A Novel Dual-Membranes WGS Reactor with Palladium Alloy and Polyvinyl Alcohol Membranes for Enhanced Hydrogen Recovery

    A novel membrane reactor concept including palladium alloy membrane (selective to H2) and polyvinyl alcohol membrane (selective to CO2) is proposed for water gas shift reaction. The mathematical model of the reactor is developed for two reactor schemes, namely plug dual-membrane reactor (PDMR) and CSTR dual-membrane reactor (CDMR) with uni-dimensional and non-isothermal conditions. A comparison between PDMR and palladium alloy membrane reactor (PAMR) showed that PDMR volume becomes 30 % less than PAMR with 20 bar increase in feed pressure. Then the effect of Damkholer number, feed composition, and feed pressure on hydrogen recovery and CO conversion for PDMR and CDMR has been studied. Under the same operating conditions, CO conversion in PDMR is 10 % more than CDMR while its temperature decreases. The new proposed reactor configuration could pave the way for simultaneous production of hydrogen, increased CO conversion, and CO2 separation on an industrial scale

    Bayesian Analysis of Doubly Inflated Poisson Regression for Correlated Count Data: Application to DMFT Data

    Get PDF
    Outcome variables in clinical studies sometimes include count data with inflation in two points (usually zero and k (k>0)). Doubly inflated models can be adopted for modeling these types of data. In statistical modeling, the association among subjects due to longitudinal or cluster study designs is considered by random effects models. In this article, we proposed a doubly inflated random effects model using the Bayesian approach for correlated count data with inflation in two values, and compared this model with Bayesian zero-inflated Poisson and Bayesian Poisson models. The parameters’ estimates by these models were obtained by Markov Chain Monte Carlo method using OpenBUGS software. Bayesian models were compared using the deviance information criterion. To this end, we utilized the total number of decayed, missed, and filled teeth of 12-year-old children and also conducted a simulation study.  Results of real data and the simulation study revealed that the proposed model is fitted better than previous models.&nbsp

    The current trend of exosome in epithelial ovarian cancer studies: A bibliometric review

    Get PDF
    Background: Epithelial ovarian cancer (EOC) is the most common type of ovarian cancer. About 90% of ovary tumors are epithelial. The current treatment for EOC involves surgical debulking of the tumors followed by a combination of chemotherapy. While most patients achieve complete remission, many EOCs will recur and develop chemoresistance. The cancer cells can adapt to several stress stimuli, becoming resistant. Therefore, new ways to fight resistant cells during the disease are being studied. Recently, exosomes, which reflect cell behavior in normal and pathological conditions such as epithelial ovarian cancer, are of academic interest as new biomarkers for diagnosis and therapy. Consequently, the current study aimed to investigate the research output of exosomes in EOC. Method: A bibliometric method was used for analyzing publications on exosome and epithelial ovarian cancer from the beginning to 15 October 2022 by searching keywords in Scopus, PubMed and Google scholar. Annual scientific publications, authors, citations, journals, co-authorships, and keywords co-occurrence were analyzed and plotted using Microsoft Office Excel and VOS viewer. 39 original journal articles and 3 reviews have been published since 2015 up to 15 October 2022. Results: The findings showed that China is the top country in research output, international collaborations, organization, author, and sponsorship. The top journals were the Journal of Ovarian Research, Oncotarget, and Tumor Biology, all in the United States. The top institution was Shanghai Jiao Tong University in China. The top author was Xipeng Wang. Co-occurrence analysis showed that academics’ interest is toward:1) 1) Exosomes as prognostic biomarkers of EOC as well as their role in the proliferation and migration of cells. 2) The role of exosomes in metastasis through different mechanisms; 3) The role of exosomes in epithelial-mesenchymal transition of ovarian cancer cells; 4) The diagnostic role of EVs in EOC; and 5) Conferring chemoresistance in EOC through the exosomal transfer of miRNAs. Conclusion: Research on the exosome and EOC has an increasing trend, and China is much more involved than other countries in research, financial support, and international cooperation. These findings could aid researcher in understanding novel ideas and subjects interested by sponsors in this field. Copyright © 2023 Baghban, Ullah and Nabipour

    The Effects of Folic Acid Supplementation on Recurrence and Metabolic Status in Endometrial Hyperplasia: A Randomized, Double-Blind, Placebo-Controlled Trial

    Abstract: Background: Data on the effects of folic acid supplementation on clinical symptoms and metabolic profiles of patients with endometrial hyperplasia (EH) are limited. This investigation was performed to evaluate the effects of folic acid supplementation on clinical symptoms and metabolic status of patients with EH. Methods: This randomized, double-blind, placebo-controlled trial was conducted among 60 women diagnosed with EH. Diagnosis of EH was made based on biopsy results. Participants were randomly allocated to 2 groups to take 5 mg/d folic acid supplements (n = 30) or placebo (n = 30) for 12 weeks. Results: After the 12-week intervention, folic acid supplementation significantly decreased fasting plasma glucose (β -3.99 mg/ dL; 95% CI, -7.39, -0.59; P = 0.02), serum insulin levels (β -2.82 µIU/mL; 95% CI, -4.86, -0.77; P = 0.008), homeostasis model assessment for insulin resistance (β -0.68; 95% CI, -1.20, -0.17; P = 0.009), triglycerides (β -16.47 mg/dL; 95% CI, -28.72, -4.22; P = 0.009) and very-low-density lipoprotein (VLDL) cholesterol (β -3.29 mg/dL; 95% CI, -5.74, -0.84; P = 0.009), and significantly increased the quantitative insulin sensitivity check index (β 0.01; 95% CI, 0.004, 0.03; P = 0.01) compared with the placebo. Additionally, folic acid intake resulted in a significant reduction in serum high sensitivity C-reactive protein (hs-CRP) (β -0.36 mg/L; 95% CI, -0.52, -0.21; P < 0.001) compared with the placebo. Folic acid supplementation did not affect other metabolic parameters. Conclusion: In conclusion, we found that folic acid administration for 12 weeks to subjects with EH improved glycemic control, triglycerides, VLDL-cholesterol and hs-CRP levels, but did not influence recurrence and other metabolic profiles

    Cupping: a reasonable choice for attenuating morphine withdrawal symptoms in Wistar rats

    Get PDF
    Background: Nowadays, the sedative drugs are the main treatments to attenuate the opioid withdrawal symptoms. However, physical therapies are found a safe alternative treatment without any serious adverse effects. This study aimed to evaluate the effects of cupping treatment on the morphine withdrawal symptoms in rats.Methods: Eighty rats were divided into two main groups; treated with morphine or saline, and each group was also divided to cupping and sham cupping subgroups (with single or daily treatment). Injection of morphine and saline were done in the morphine and saline groups twice a day for nine days. On the ninth day, the naloxone was administered and the withdrawal symptoms including jumping, rearing, body grooming, abdominal writing, and wet-dog shaking were recorded for 60 minutes. Cupping or sham cupping was applied on the GV14 once before or daily after withdrawal induction in each group.Results: The results revealed that a single cupping before the withdrawal induction significantly attenuated the withdrawal symptoms in the morphine group (p<0.01).But, the daily cupping failed to decrease the withdrawal symptoms in this group. The results also indicated that the daily cupping in the saline group increased the naloxone-induced withdrawal symptoms significantly (p<0.01).Conclusions: Single session cupping before the withdrawal induction could decreased the withdrawal symptoms. This finding might be related to the modulation of GABAergic system

    Three-dimensional and two-dimensional relationships of gangliogenesis with folliculogenesis in mature mouse ovary: a Golgi–Cox staining approach

    Get PDF
    The present study was set out to investigate two-dimensional (2D) and three-dimensional (3D) evaluations of ovarian nervous network development and the structural relationship between folliculogenesis and gangliogenesis in mouse ovaries. Adult mice ovarian tissue samples were collected from follicular and luteal phases after cardiac perfusion. Ovarian samples were stained by a Golgi–Cox protocol. Following staining, tissues were serially sectioned for imaging. Neural filaments and ganglia were present in the ovaries. In both 2D and 3D studies, an increase in the number and area of ganglia was seen during the follicular growth. The same pattern was also seen in corpora lutea development. However, in some cases such as ratio of ganglia number to follicle area, the ratio of ganglia area to follicular area, 2D findings were different compared with the 3D results. 3D analysis of ovarian gangliogenesis showed the possible direct effect of them on folliculogenesis. Golgi–Cox staining was used in this study for 3D evaluation in non-brain tissue. The results of 3D analysis of the present study showed that, in some cases, the information provided by 2D analysis does not match the reality of ovarian neuronal function. This confirmed the importance of 3D analysis for evaluation of ovarian functio
