Purpose The phenolic composition, antioxidant, antimicrobial activity, enzyme inhibition activity, and cytotoxic activity potentials of the plant Rumex acetosella L. (R. acetosella) were examined in this study. Materials and Methods: The chemical composition of R. acetosella methanol extract was identified by the LC-MS/MS method. The antioxidant activity was tested using beta-carotene/linoleic acid, DPPH free radical scavenging, ABTS cation radical scavenging, CUPRAC reducing power, and metal chelating activity methods. The cytotoxic activity was determined by the MTT assay using human ovarian adenocarcinoma (Skov-3), glioblastoma (U87), human dermal fibroblasts (HDF), and human colorectal adenocarcinoma (CaCo-2) cell lines. The antimicrobial activity of methanolic extracts was tested on gram-negative (Escherichia coli and Pseudomonas aeuriginosa) and gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) using the in vitro minimum inhibition concentration method (MIC). Enzyme inhibition activity of R. acetosella methanol extract was measured spectrophotometrically against acetylcholinesterase (AChE) and glutathione S-transferase (GST) enzymes. Results: The findings showed that the major components of the methanol extract content were luteolin-7-O-glucoside (1.599 m/L), polydatin (91,024 m/L), and shikimic acid (0.773 m/L). It was determined that the extract and standard antioxidant (a-tocopherol) results in DPPH center dot, and ABTS center dot + tests performed to determine the antioxidant activity were close to each other, and this value was more effective than the standard antioxidant (alpha-tocopherol) in the CUPRAC test. These results suggested that the plant's antioxidant potential was higher when compared with reference antioxidant compounds. It was determined that the methanol extract of R. acetosella had a weaker effect on the growth of the tested microorganisms than the antibiotics used as standard. The activity of the GST and AChE enzymes was found to be severely inhibited by the methanol extract of R. acetosella. Conclusion: Based on these findings, R. acetosella L. is a medicinal and commercially beneficial plant that warrants further investigation.

(Springer Publishing Co, 2024) Yeşil, Yeşim; Bay, Habibe; Celik, Gulbiye Dinc; Bay, Habibe; Eksioglu, Aysun; Turfan, Esin Ceber
Objective: This study aims to evaluate the effect of the delivery method on breastfeeding status of primiparous mothers during the first 24 hours. Methods: In this descriptive and analytical study, the sample consisted of 126 primiparous mothers with vaginal (n = 54) and cesarean (n = 72) deliveries. The research data were collected in a hospital through a personal information form and LATCH. Breastfeeding was assessed at the 6th, 12th, and 24th hours within the first 24 -hour period after the delivery. Results: A total of 83.3% of mothers with vaginal delivery started out breastfeeding in the first hour, while the rate was 43.1% for mothers with cesarean delivery. A total of 94.4% of mothers who had vaginal birth gave their babies colostrum, whereas the rate was 80.6% for mothers who had a cesarean birth. While there were no statistically significant differences in Applications 1 and 3 between the LATCH scores of mothers with vaginal and cesarean deliveries, Application 2 produced a significant difference (p < .05). Conclusions: Delivery method influenced the breastfeeding behavior and had an impact particularly on initiation of breastfeeding in the first hour.
Pelvic floor muscle strength and dysfunctions in women with pes planus: A case-control study
(Churchill Livingstone, 2024) Yardımcı, Fatma Betül; Yardimci, F.B.; Altay, H.
Background/aim: Distal extremity misalignment may give rise to pelvic floor dysfunctions (PFDs). This study aimed to compare pelvic floor muscle strength (PFMS) and dysfunctions in women with and without pes planus. Materials and methods: Women with (pes planus group, n = 30) and without pes planus (control group, n = 30) were included. The presence of PFDs questioned. Pes planus with the Feiss Line Test, PFMS with the Modified Oxford Scale, and the severity of PFDs with the Pelvic Floor Distress Inventory-20 (PFDI-20), including three subscales (Pelvic Organ Distress Inventory-6 (POPDI-6) for pelvic organ prolapse, Colorectal-Anal Distress Inventory-8 (CRADI-8) for colorecto-anal symptoms, and Urinary Distress Inventory-6 (UDI-6) for urinary symptoms, were assessed. Results: It was seen that no difference was found between groups in terms of PFMS (p > 0.05). However, urinary incontinence and anal incontinence were higher in women with pes planus than in women without pes planus (p < 0.05). Only the PFDI-20, CRADI-8, and UDI-6 scores were higher in women with pes planus compared to controls (p < 0.05). There was no difference was found between groups in terms of POPDI-6 scores (p > 0.05). Conclusion: The PFMS did not change according to the presence of pes planus. However, the prevalence of PFDs and their severity were higher in women with pes planus in comparison to controls. Posture assessments of individuals with PFDs, especially examination of foot posture, and pelvic floor assessments of individuals with posture disorders should be considered. © 2024
