The impact of Ki-67 index, squamous differentiation, and several clinicopathologic parameters on the recurrence of low and intermediate-risk endometrial cancer

Endometrial endometrioid carcinoma (EEC) represents approximately 75-80% of endometrial carcinoma cases. Three hundred and thirty-six patients with EEC followed-up in the authors’ medical center between 2010 and 2018 were included in our study. Two hundred and seventy-two low and intermediate EEC patients were identified using the European Society for Medical Oncology criteria and confirmed by histopathological examination. Recurrence was reported in 17 of these patients. The study group consisted of patients with relapse. A control group of 51 patients was formed at a ratio of 3:1 according to age, stage, and grade, similar to that in the study group. Of the 17 patients with recurrent disease, 13 patients (76.5%) were Stage 1A, and 4 patients (23.5%) were Stage 1B. No significant difference was found in age, stage, and grade between the case and control groups (p > 0.05). Body mass index, parity, tumor size, lower uterine segment involvement, SqD, and Ki-67 index with p<0.25 in the univariate logistic regression analysis were included in the multivariate analysis. Ki-67 was statistically significant in multivariate analysis (p = 0.018); however, there was no statistical significance in SqD and other parameters. Our data suggest that the Ki-67 index rather than SqD needs to be assessed for recurrence in patients with low- and intermediate-risk EEC

Endoscopic plantar fascia release versus cryosurgery for the treatment of chronic plantar fasciitis: A prospective randomized study

Background: In a prospective randomized study, we compared two different surgical techniques used in plantar fasciitis surgery. Methods: Forty-eight patients diagnosed as having plantar fasciitis and treated for at least 6 months with no response to conservative modalities were included in this study. The patients were randomly assigned to receive endoscopic plantar fascia release (EPFR) or cryosurgery (CS). Patients were evaluated using the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS-AHS) as a primary outcome measurement at baseline and 3 weeks and 3, 6, and 12 months after surgery. At the final follow-up visit, the Roles-Maudsley score was used to determine patient satisfaction. Results: Five patients did not complete the 1-year follow-up examination (one in the EPFR group and four in the CS group). Thus, the study group included 43 patients. Although both groups showed significant improvement at the final evaluation, the patients in the EPFR group had significantly better AOFAS-AHS scores at 3 months. The success rate (Roles-Maudsley scores of excellent and good) in the EPFR group at 12 months was 87% and in the CS group was 65%. Conclusions: Both EPFR and CS were associated with statistically significant improvements at 1-year follow-up. At 3-month follow-up, EPFR was associated with better results and a higher patient satisfaction rate compared with CS

Long-Term Dietary Fructose Causes Gender-Different Metabolic and Vascular Dysfunction in Rats: Modulatory Effects of Resveratrol

Background/Aims: There is limited knowledge on the gender differences in the effects of dietary fructose. In the current study, we investigated whether long-term fructose intake impacts metabolic parameters and vascular reactivity differently between male and female rats. Moreover, we tested whether resveratrol has a gender-specific effectiveness on the alterations. Methods: Male and female rats were divided into four groups as control; resveratrol; fructose and resveratrol plus fructose. Fructose was given to the rats as 10% solution in drinking water for 24 weeks. All rats were fed with the standard diet with or without resveratrol. Results: High-fructose diet increased plasma insulin, triglyceride and VLDL levels as well as omental weights in both genders. Long-term dietary fructose causes marked increase in body weight of males, but not females. Dietary fructose impaired endothelial relaxation to acetylcholine and intensified contraction to phenylephrine in the aortas of male and female rats, but differently it also reduced insulin-induced vasodilation in aortas of female rats. These changes were associated with decreased expression levels of endothelial nitric oxide synthase (eNOS) mRNA and protein, but increased in inducible NOS (iNOS), in aortas of male and female rats. Dietary fructose suppressed expression levels of sirtuin 1 (SIRT1) and insulin receptor substrate-2 (IRS-2) mRNA in aortas from female rats. Resveratrol supplementation efficiently restored fructose-induced metabolic and vascular dysfunction in both genders probably by regulating eNOS and iNOS production. Moreover, the augmentations in SIRT1 and IRS-2 mRNA in females and IRS-1 mRNA in males may possibly contribute to the beneficial effects of resveratrol as well. Conclusion: Long-term fructose intake may differently affect metabolic and vascular function between male and female rats, which are modified by resveratrol

Differential gene expression in liver tissues of streptozotocin-induced diabetic rats in response to resveratrol treatment.

This study was conducted to elucidate the genome-wide gene expression profile in streptozotocin induced diabetic rat liver tissues in response to resveratrol treatment and to establish differentially expressed transcription regulation networks with microarray technology. In addition to measure the expression levels of several antioxidant and detoxification genes, real-time quantitative polymerase chain reaction (qRT-PCR) was also used to verify the microarray results. Moreover, gene and protein expressions as well as enzymatic activities of main antioxidant enzymes; superoxide dismutase (SOD-1 and SOD-2) and glutathione S-transferase (GST-Mu) were analyzed. Diabetes altered 273 genes significantly and 90 of which were categorized functionally which suggested that genes in cellular catalytic activities, oxidation-reduction reactions, co-enzyme binding and terpenoid biosynthesis were dominated by up-regulated expression in diabetes. Whereas; genes responsible from cellular carbohydrate metabolism, regulation of transcription, cell signal transduction, calcium independent cell-to-cell adhesion and lipid catabolism were down-regulated. Resveratrol increased the expression of 186 and decreased the expression of 494 genes in control groups. While cellular and extracellular components, positive regulation of biological processes, biological response to stress and biotic stimulants, and immune response genes were up-regulated, genes responsible from proteins present in nucleus and nucleolus were mainly down-regulated. The enzyme assays showed a significant decrease in diabetic SOD-1 and GST-Mu activities. The qRT-PCR and Western-blot results demonstrated that decrease in activity is regulated at gene expression level as both mRNA and protein expressions were also suppressed. Resveratrol treatment normalized the GST activities towards the control values reflecting a post-translational effect. As a conclusion, global gene expression in the liver tissues is affected by streptozotocin induced diabetes in several specific pathways. The present data suggest the presence of several processes which contribute and possibly interact to impair liver functions in type 1 diabetes, several of which are potentially amenable to therapeutic interventions with resveratrol

Outlanders at work: An interpretative phenomenological analysis of foreign IT professionals’ work experiences in Germany

The information technology (IT) industry is becoming more widely renowned for its professionals seeking global career opportunities. These individuals independently build careers abroad, often receiving limited economic benefits while facing socially conditioned perceptions from their employers, peers, managers, and clients. However, there is little research on how they perceive their personal and social worlds, and use their knowledge, skills, and other personal resources to shape their careers in these circumstances. This study explores the meaning of being a foreign professional as understood by the IT professionals themselves by reflecting on their expectations, emotions, and interactions with others. In-depth interviews were conducted with eleven non-national professionals working in domestic IT companies in Germany. We used interpretative phenomenological analysis to gain insight through their individual perspectives into their agentic work behaviours and the injustices they perceived. We identified three major themes that explained how participants interpreted their roles in their organisations (reinterpretation), resituated themselves in their interactions with clients (recontextualisation) and changed the way they made sense of their status in their current circumstances (reframing). The experiential themes were discussed in light of literature, while individual nuances led us to identify unexplored features of the studied phenomenon

High-fructose corn syrup-induced hepatic dysfunction in rats: improving effect of resveratrol

WOS:000359821400003PubMed:25238689The increased consumption of high-fructose corn syrup (HFCS) may contribute to the worldwide epidemic of fatty liver. In this study, we have investigated whether HFCS intake (20 % beverages) influences lipid synthesis and accumulation in conjunction with insulin receptor substrate-1/2 (IRS-1; IRS-2), endothelial nitric oxide synthase (eNOS), sirtuin 1 (SIRT1) and inducible NOS (iNOS) expressions in liver of rats. Resveratrol was tested for its potential efficacy on changes induced by HFCS. Animals were randomly divided into four groups as control, resveratrol, HFCS and resveratrol plus HFCS (resveratrol + HFCS). HFCS was given as 20 % solutions in drinking water. Feeding of all rats was maintained by a standard diet that enriched with or without resveratrol for 12 weeks. Dietary HFCS increased triglyceride content and caused mild microvesicular steatosis in association with up-regulation of fatty acid synthase and sterol regulatory element binding protein (SREBP)-1c in liver of rats. Moreover, HFCS feeding impaired hepatic expression levels of IRS-1, eNOS and SIRT1 mRNA/proteins, but did not change iNOS level. Resveratrol promoted IRS, eNOS and SIRT1, whereas suppressed SREBP-1c expression in rats fed with HFCS. Resveratrol supplementation considerably restored hepatic changes induced by HFCS. The improvement of hepatic insulin signaling and activation of SIRT1 by resveratrol may be associated with decreased triglyceride content and expression levels of the lipogenic genes of the liver.Gazi University Research FundGazi University [BAP 02/2011-39, 02/2012-48]This study was supported by grants from Gazi University Research Fund (BAP 02/2011-39 and 02/2012-48)
