    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.

    Eating Behavior Changes of People With Obesity During the Covid-19 Pandemic
    (Dove Medical Press Ltd, 2021) Deger, Vasfiye Bayram
    Objective: The precautions taken during the pandemic period may cause stress-related eating behavior disorders. It was aimed to test this hypothesis, and the study was carried out to examine pandemic measures the effect of on the nutritional, depression and stress conditions of people with obesity. Methods: The individuals who participated in the study were people with obesity who received follow-up dietary therapy in a private hospital. Three separate scales were applied to the individuals, which measured the desire to overeating request, depression status and stress-fighting status. Results: This study was conducted on 368 individuals. Women had lower values of BMI (28.57 +/- 3.89 kg/cm(2)) than men ( 30.64 +/- 2.87 kg/cm(2)). When the scores of the excessive eating request scale mean scores before and during the pandemic were examined, it was seen that the scores of the individuals increased during the pandemic. In the multivariate regression model, it was seen that the increase of stress and BMI increased the FCQ score (p<0.001). Multiple regression models were created by taking into account the criteria that caused the score increase. Each variable can predict the FCQ score separately. The predictor significance order of variants on FCQ score beta values is as follows: the Patient Health Questionnaire-9 (PHQ-9) (beta=0.774), before pandemic FCQ (beta = 0.601), the Perceived Stress Scale ( PSS) (beta=-0.268), before pandemic BMIa (beta=-0.223), during pandemic BMIb (beta=0.073), and age (beta=-0.013). Conclusion: COVID-19 pandemic, making applications such as quarantine in pandemic processes has successful results in being able to combat its. However, undesirable conditions such as stress can have serious negative consequences on other health measurements. It was observed in the results of this study that excessive eating food desire developed in people with obesity.
