Childbirth induces a number of alterations, including ligament weakening and increased vaginal distensibility. The occurrence of vaginal laxity or distensibility is associated with the vaginal wall and introitus overstretching during vaginal parturition while the pathophysiology is due to increased levator dimension and trauma to the levator ani muscle through avulsion (macrotrauma) or overdistension (microtrauma). Elastin is an extracellular matrix protein that confers elastic properties to organs and tissues, particularly those requiring elasticity. Elastin plays a vital role in the functioning of numerous tissues, such as the lungs, blood vessels, heart valves, ligaments, tendons, and skin. It is also a component of the vaginal mucosa. The aim of the present was to evaluate the role of elastin in the thickening of the postpartum vaginal wall composed of epithelial mucosa, and to understand the mechanism underlying vaginal laxity or distensibility within parous and nulliparous animal models. A total of 32 female white rats (Rattus norvegicus) were used in the present study. They were divided into two groups, each group consisting of 16 rats. The control group (C0) consisted of virgin nulliparous rats, which were sacrificed on the second day after vaginal parturition. Pregnant rats (group C1) were sacrificed on the second day after vaginal parturition. The median elastin expression in group C1 was higher (3 ± 0.56) than group C0 (2.85 ± 0.75). The mean thickness of the vaginal mucosal epithelium in group C0 (56,8 931µm) was greater than group C1 (44,98 349µm). The comparison of vaginal mucosal epithelium thickness between the two groups indicated a significant difference between groups C0 and C1. Elastin levels were significantly correlated with epithelial thickness. The expression of elastin significantly affects the vaginal wall thickness, which further affects vaginal laxity or vaginal distensibility.

Streptococcus agalactiae are pathogenic bacteria which cause vaginal infection. Vaginal and cervical infections in pregnant women can reduce elasticity of the membranes that cause premature rupture of membranes. This can also impact to neonatal morbidity and mortality in first week of birth. Kefir is known as a probiotic that can act as an immunomodulator. The role of kefir is believed to improve the immune system. The role of kefir in preventing infection is still rarely studied, especially as an immunomodulator and in reducing the number of pathogenic bacteria.This study aimed to evaluate superoxide dismutase (SOD) level, Malondialdehyde (MDA) level, and the population of the colonization Streptococcus agalactiae in BALB-C mice fed kefir. This study was true experimental with post test only control group design. Sample was BALB-C mice induced by Streptococcus agalactiae. SOD and MDA level was examined by enzyme-linked immunosorbent assay (ELISA) and Streptococcus agalactiae identification by colony count. The results of the one-way ANOVA analysis showed there was no significant differences between all groups for SOD levels (P 0.393). In the level of MDA there was also no difference between all groups (P 0.204). Whereas in the number of Streptococcus agalactiae colonies there was a significant difference (P 0.000) with the smallest number of colonies found at dose of 0.5 ml / day. Conclusion: kefir as a probiotic drink did not affect to the SOD and MDA level of BALB/ C mice induced by Streptococcus agalactiae, but kefir affected to number of Streptococcus agalactiae colonies. Further research needs to show the relation of kefir as probiotics with proinflammatory and other anti-inflammatory parameters such as interleukin and immunological vaginal mucosa.

ABSTRACT Toilet training is an effort to train children to be able to control and urinate (BAK) and defecate (BAB). Toilet training is one of the main tasks of children at toddler age. Toilet training is one of the main tasks of children in toddler age which is very important to be done to create independence in children in controlling BAK and BAB and children know the parts of the body and their functions. Data in 2012 shows that ± 60% of parents do not teach toilet training to children from an early age. The aim of the study was to find out the effectiveness of toilet training education on maternal behavior and toilet skills in toddler age training (18-36 months). The study was conducted in July-August 2018. This type of quantitative research used the design of the Quasy pretest and posttest experiment with non-equivalent control group design. Samples were 36 mothers and 36 children with purposive sampling technique. Data analysis used Paired t test, Wilcoxon test, Man-Whitney test an Independent t test. The results showed that toilet training education through lecture methods, modules and maze games was more effective than toilet training education through lecture and leaflet methods on children's knowledge and abilities. Conversely, for the role of mothers in supervision there is no significant difference in effectiveness. Health education is recommended in health promotion programs to increase maternal knowledge, the role of mothers and the ability of toilet training children independently. Keywords: Toilet training, Lecture method, Module, Maze game, Leaflet, Knowledge, Role of mother, Children's ability.

Objective: India is the second country after China having the highest population prevalence of diabetes. Several research studies investigating diabetes have been done, but not much work has been done on prediabetes. The purpose of this study was to investigate the effect of nutrition and lifestyle modification on prediabetic females. Methods: A total of 120 prediabetic females from Ludhiana city were divided into 2 matched groups: control group (n = 60) and experimental group (n = 60). Impact of nutrition intervention for dietary and lifestyle modification (for 3 months) was assessed on the anthropometric, dietary, biochemical parameters, and diabetes risk score of the experimental group and control group (no intervention). Results: All the selected 120 subjects completed the study (experimental group = 60; control group = 60). There was significant difference in the changes between the 2 groups throughout the study. The fasting blood glucose and glycated hemoglobin A1c levels of the experimental group subjects reduced significantly ( P ≤ .01). However, no change was observed among the control group subjects. The lipid profile of the experimental group showed a significant improvement ( P ≤ .01). Conclusion: Nutrition counselling of the prediabetics regarding dietary and lifestyle modification is recommended so as to improve their metabolic control, thus preventing them from being diabetics.

AbstractPatients afflicted with melanoma show lower vitamin D serum levels (VDSL) than the healthy population. This hypothesis agrees with its well-known antiproliferative features. An observational study was carried out to collect VDSL in patients suffering from melanoma. Our aim was to identify a potential connection between low VDSL and the risk to incur melanoma. Furthermore, we studied the association between VDSL at the diagnosis of melanoma and other germane prognostic factors. The population held in regard was composed of 154 patients with a diagnosis of melanoma between 2016 and 2019. These patients were retrospectively collected from our follow-up storage. We compared VDSL to clinical and pathological parameters (age, sex, tumour location, Breslow’s depth, Clark’s level, histological subtype, ulceration, et aliqua). Moreover, we recruited a control group with negative melanoma history. Mean and median of VDSL were significantly lower in the melanoma group. Instead, we found a negative association between melanoma and VDSL > 30 ng/L (OR 0.11; p < 0.0001). No correlation between VDSL and both Breslow’s depth and Clark’s level was discovered, but the VDSL comparison between thin (depth ≤ 1 mm) and thick tumours (depth > 1 mm) revealed a statistically significant difference (21.1 ± 8.2 ng/L vs 17.8 ± 8.1; p = 0.01). Moreover, VDSL were significantly lower in melanomas with mitotic rate ≥ 1/mm2 (22.1 ± 8.3 ng/L; p < 0007). Nevertheless, no connection was found between VDSL and both ulceration and positive sentinel nodes (p = 0.76; p = 0.74). Besides, our study revealed no association between VDSL and histological subtype (p = 0.161). Lower VDSL correlate with thick and high mitotic rate tumours. Future prospective studies would investigate if appropriate upkeep of suitable VDSL can decrease the risk of primary and recurrent melanoma diagnosis.

<p>The present study was an attempt to investigate the effect two types of corrective feedback (i.e., recast and metalinguistic) in order to find out which one is more effective on EFL learners’ speaking improvement and also to see if gender could play a role in the relative impact of the two types of corrective feedback on learners’ speaking ability. To this end, 65 EFL learners of intermediate level in one of language institutes in Shiraz, Iran were selected and divided into three groups including two experimental groups and one control. The instruments used to collect the data included IELTS test as the pre and post tests and Oxford Placement Test (OPT) in order to obtain the homogeneity in participants’ English proficiency. The collected data were codified and entered into SPSS Software (Version 22) and were analysed using descriptive statistics, t-test, and Tukey test. The results indicated that although applying these two types of corrective feedback could have made improvement in EFL learners’ speaking ability, there was not observed any significant difference between impacts of recast and metalinguistic on EFL learners’ production. The test results also indicated that there was not any significant difference regarding gender within the three groups. This homogeneity further shows that in this study, the gender variable did not have any effect on the role of corrective feedback and it can be concluded that the observed difference between metalinguistic group, recast group, and control group is just the result of the provided corrective feedback type which has acted as the intervening variable and the moderator variable such as gender did not prove to have any effect in the outcome of this study. The findings can contribute to syllabus design and teaching methodology areas.</p>

Abstract Background: Chemical trauma to the cornea is an emergency condition of the eye that requires early diagnosis and good treatment. Alkaline have ability to saponify fatty acids in cells and cell membranes which can make penetration into the stroma and destroy proteoglycans and collagen in cells. Aloe vera (AV) contains several active substances that are reported to have anti-inflammatory, immunomodulatory, and wound healing effects. AV has been reported to accelerate the healing process of corneal epithelial defects by increasing fibroblast proliferation, collagen production and growth factor production. This study aims to determine the difference between the effect of aloe vera extract with a concentration of 10%, 20%, 40% and BSS on the healing of extensive corneal lesions in white wistar rats alkaline trauma models. Method: This study was an experimental study with a pre and posttest only with control group design in vivo approach to 30 Wistar white rats which were divided into 5 treatment groups for 3 days. Comparative analysis of effectiveness using the ANNOVA test or the Kruskal Wallis test and continued by the post hoc test. Results: Based on the one way ANOVA test there was a statistically significant difference in effectiveness between the five treatment groups on the percentage of corneal wound healing area and TGF-β expression with an assessment of p = 0,000 each. The administration of alloevera (AV) concentration of 20% had a significant difference in percentage of healing of corneal lesions and TGF-β expression compared with other treatment groups with p = 0,000 each. Large differences in the area of corneal lesions in the 40% AV group were -0.45 in the BBS group, 0.146 in the 10% AV group, 0.493 in the 20% AV group. The difference in the AV group 10% was 0.30 in the BBS group, -064 in the AV group 20%, and -0.14 in the AV group 40%. However, TGFβ expression in the normal control group that did not receive treatment was 54.94 (53.21-56-12). TGFβ levels in the BSS group were 10.44, the 10% aloe vera group was 25.43, 47.99 for the 20% aloe vera group and 37.95 for the 40% aloe vera group. Conclusion: There is a difference between the effect of aloe vera extract with concentrations of 10%, 20%, 40% and BSS on the extensive healing of corneal lesions in white wistar rats with alkaline chemical trauma models.

Abstract Study question Could Nrf2 polymorphism (-617C&gt;A; rs6721961) and oxidative stress (OS)-induced changes of signature seminal plasma (SP) miRNAs related to Nrf2 provide possible biomarkers of male infertility? Summary answer -617C&gt;A SNP is associated with infertility through sperm OS DNA damage and miR-582-5p and miR-20a-5p, differentially represented between spermatozoa of smokers-non-smokers, might regulate Nrf2/ARE axis. What is known already As an extrinsic factor causing OS, smoking decreases male infertility by causing sperm membrane damage and DNA fragmentation. Expression of proteins related to the antioxidant defense system and phase 2 detoxifying enzymes controlled mainly by Nrf2/ARE pathway components is vital in managing OS-induced DNA damage. miRNAs, which multiple of are produced abundantly in male germ cells throughout spermatogenesis, have been detected in SP and contribute to multiple biological processes related to male reproductive events. miRNA-expression alterations may be induced in response to OS and without involving DNA sequence changes, miRNAs can provide additional mechanism of regulating the Nrf2 gene expression. Study design, size, duration Wild-type (WT) and SNP (-617) alleles in the Nrf2 gene were studied in 100 infertile cases and 100 controls and their associations with seminal parameters in relation to smoking status were assessed. In infertile cases, sperm DNA damage level was determined and compared among Nrf2 genotypes. Interactions between differentially expressed miRNAs (DEMIs) in response to smoking and Nrf2/ARE pathway components were visualized on a miRNA-mRNA regulatory network using CluePedia (v1.5.7) plugin of Cytoscape software (v3.8.2). Participants/materials, setting, methods Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was utilized to genotype the Nrf2 SNP (-617). DNA damages were analyzed by Comet assay. DEMIs were identified by a comprehensive bioinformatics analysis using the miRNA expression dataset GSE44134 downloaded from the GEO database. Predicted targets of DEMIs in smokers were identified by mirDIP portal. Known interactions between Nrf2 and its first neighbors were visualized after selecting STRING-actions, miRTarBase and miRecords validated miRNA source files from CluePedia panel. Main results and the role of chance There was significant difference for Nrf2 polymorphism between fertile and infertile males. The A allele was detected more frequently in the patient group; (P = 0.001). The frequencies of the C and A alleles of the Nrf2 were 62% and 38% in patients, and 78% and 44% in control group. The AA genotype was higher in the infertiles; 14% vs. 3% (P = 0.001). In smokers, sperm quality decreased significantly in AA genotype. The risk of DNA damage was highest with 224.58 AU in the AA genotype group, whereas it is the lowest with 164.56 AU in those carrying the CC genotype (P &lt; 0.005). 21 differentially expressed miRNAs (including 7 downregulated and 14 upregulated in smokers) were identified. Among the upregulated DEMIs, miR-582-5p, miR-20a-5p, miR-573, miR-186-5p, miR-499a-5p were found to target the Nrf2 mRNA, suggesting their usage as biomarkers capable of indicating the antioxidant ability of the male reproductive system. The interrelations between Nrf2/Nrf2 direct interactors and DEMIs revealed the regulatory role of hsa-miR-20a-5p in SQSTM1/p62-Keap1-Nrf2 axis linked to selective autophagy. hsa-miR-582-5p was found to regulate the JNK/Jun/caspase-3 pathway, previously shown to be activated in response to OS, in which JUN can activate or suppress the Nrf2 expression. Limitations, reasons for caution Small number of cases while evaluating the effect of smoking weakens our ability to generalize the results. Including other coexisting factors and larger patient groups carrying other functional variants of Nrf2 as well as confirming the results at the protein level would further strengthen the results of the study. Wider implications of the findings This study is the first to report -617C&gt;A polymorphism in the Nrf2 gene in the Turkish population and such a SNP may cause impaired fertility in men, especially in smokers, through oxidative metabolism. Considering these data may be valuable in determining risk groups. Trial registration number N/A

Objective: The objective of the study was to evaluate the antidepressant activity of quercetin in monosodium glutamate (MSG) model of depressed male mice. Methods: MSG was administered (500 mg/kg) to different groups of albino male mice daily for 21 days to induce depression. The interventions (Quercetin and imipramine) were started on day 9th and continued till 21st day. On 23rd day, mice are sacrificed, hippocampus and amygdala supernatant are subjected for analysis. p<0.05 was considered as statistically significant. Results: There was a statistically significant reduction in interleukin (IL)-6 levels in animals treated with quercetin and imipramine compared to control group (p<0.001). There was also a statistically significant increase in brain-derived neurotrophic factor (BDNF) levels in quercetin with MSG groups (p<0.05) and imipramine with MSG groups (p<0.01). There was no statistically significant difference in IL-6 and BDNF levels between the groups of animals treated with quercetin (100 mg/kg) and imipramine (10 mg/kg) alone. Conclusion: Quercetin appeared to have an antidepressant activity. More extensive research is required to substantiate and elucidate the role of quercetin in behavioral disorders such as depression.
