UC usually worsens the daily life of the patient and may sometimes become mortal. There is no known remedy discovered against UC, yet. Rosmarinus officinalis consists of many flavonoids, phenolics, and terpenoids possessing various biological activities such as anti-inflammatory. For this reason, in the present study, anti-ulcerative colitis effect of ROME (Rosmarinus officinalis methanol extract) was investigated comprehensively by histopathological studies, a number of in vivo anti-inflammatory activities and several in vivo antioxidant activities, in addition to in vitro antioxidant activities and biochemical analyses. In addition, the toxic effects of ROME were examined. The results showed that ROME provided a significant healing effect against ulcerative colitis in rats. Both in vitro and in vivo assay results correlated with histopathological examinations. ROME exhibited minimal toxic alterations. When the results of rosemary are compared with the results of sulfasalazine, it can be suggested that instead of synthetic drugs with side effects, natural sources can be used for the treatment of various diseases. Although some activities of rosemary have been investigated in vitro in the previous studies, this is the first study revealing anti-ulcerative colitis effect of rosemary through histopathological studies, in vivo and in vitro assays as well as biochemical analyses overall. Practical applications The results revealed and proved that ROME provided a significant healing effect against ulcerative colitis in rats. When the results of rosemary are compared with the results of sulfasalazine, a commercially available drug on the market, it can be suggested that instead of synthetic drugs with side effects, natural sources can be used for the treatment of various inflammatory diseases such as UC disease. In addition, ROME possesses limited toxic alterations, but not much more than the commercial drug. As a future perspective, lethal and therapeutic doses can be examined and determined. Thus, human studies can be started through this comprehensive in vivo study on rosemary which is commonly used as an edible plant and spice all over the world.Publication Metadata only The Cytotoxic, Genotoxic and Apoptotic Effects Against Colorectal Cancer Cells in Different Concentrations of Prangos Platychlaena(2020-03-17T00:00:00Z) Aksu, Beria; KOÇYİĞİT, ABDÜRRAHİM; GÜLER, ERAY METİN; KOÇYİĞİT, ABDÜRRAHİM; GÜLER, ERAY METİNPublication Open Access Relationship between diabetic polyneuropathy, serum visfatin, and oxidative stress biomarkers(2020-07-01T00:00:00Z) GÜLER, Eray Metin; BÜYÜKAYDIN, BANU; Karaaslan, Tahsin; OLGAÇ, ATİLLA; ZORLU, MEHMET; KISKAÇ, MUHARREM; KOÇYİĞİT, ABDÜRRAHİM; BÜYÜKAYDIN, BANU; GÜLER, ERAY METİN; OLGAÇ, ATİLLA; ZORLU, MEHMET; KISKAÇ, MUHARREM; KOÇYİĞİT, ABDÜRRAHİMBackground: Diabetic polyneuropathy is a very common complication of diabetes. Numerous studies are available in terms of pathogenesis. But examination methods with low reliability are still not standardized and generally time consuming. High-sensitive, easy-to-access methods are expected. Biochemical markers are one of the subjects of research. We aimed to discover a potential biomarker that can be used for this purpose in patients with diabetes who have not yet developed symptoms of neuropathy. Aim: To determine the place and availability of visfatin and thiol-disulfide homeostasis in this disorder. Methods: A total of 392 patients with type 2 diabetes mellitus were included in the study. The polyneuropathy clinical signs were evaluated with the Subjective Peripheral Neuropathy Screen Questionnaire and Michigan Neuropathy Screening Instrument questionnaire and examination. The biochemical parameters, oxidative stress markers, visfatin, and thiol-disulfide homeostasis were analyzed and correlated with each other and clinical signs. Results: Subjective Peripheral Neuropathy Screen Questionnaire and Michigan Neuropathy Screening Instrument questionnaire with examination scores were correlated with each other and diabetes duration (P < 0.005). Neuropathy related symptoms were present in 20.7% of the patients, but neuropathy related findings were observed in 43.9% of the patients. Serum glucose, glycated hemoglobin, and visfatin were positively correlated with each other. Also, these parameters were positively correlated with the total oxidative stress index. Total and native thiol was positively correlated with total antioxidant status and negatively with oxidant status. Inversely thiol-disulfide positively correlated with higher glucose and oxidant status and negatively with total antioxidant status (P < 0.005). There was no correlation between visfatin and thiol-disulphide (P = 0.092, r = 0.086). However, a significant negative correlation was observed between visfatin and total with native thiol (P < 0.005, r = -0.338), (P < 0.005, r = -0.448). Conclusion: Diagnosis of neuropathy is one of the issues studied in patients with diabetes. Visfatin and thiol-disulfide balance were analyzed for the first time in this study with inspiring results.Publication Metadata only İntegraz inhibitörleri yaşlanmakta olan HIV hastalarında iyi bir seçenek olabilir(2020-11-29T00:00:00Z) AKKOYUNLU, YASEMİN; KOÇYİĞİT, ABDÜRRAHİM; okay, gülay; GÜLER, ERAY METİN; ASLAN, TURAN; AKKOYUNLU, YASEMİN; KOÇYİĞİT, ABDÜRRAHİM; GÜLER, ERAY METİNPublication Open Access In Vitro Hormetic Effect Investigation of Thymol on Human Fibroblast and Gastric Adenocarcinoma Cells.(2020-07-17T00:00:00Z) Günes-Bayir, A; Kocyigit, A; Guler, Eray Metin; Dadak, A; GÜNEŞ BAYIR, AYŞE; KOÇYİĞİT, ABDÜRRAHİM; GÜLER, ERAY METİNThe concept of hormesis includes a biphasic cellular dose-response to a xenobiotic stimulus defined by low dose beneficial and high dose inhibitory or toxic effects. In the present study, an attempt has been made to help elucidate the beneficial and detrimental effects of thymol on different cell types by evaluating and comparing the impact of various thymol doses on cancerous (AGS) and healthy (WS-1) cells. Cytotoxic, genotoxic, and apoptotic effects, as well as levels of reactive oxygen species and glutathione were studied in both cell lines exposed to thymol (0-600 mu M) for 24 h. The results showed significant differences in cell viability of AGS compared to WS-1 cells exposed to thymol. The differences observed were statistically significant at all doses applied (P <= 0.001) and revealed hormetic thymol effects on WS-1 cells, whereas toxic effects on AGS cells were detectable at all thymol concentrations. Thymol at low concentrations provides antioxidative protection to WS-1 cells in vitro while already inducing toxic effects in AGS cells. In that sense, the findings of the present study suggest that thymol exerts a dose-dependent hormetic impact on different cell types, thereby providing crucial information for future in vivo studies investigating the therapeutic potential of thymol.Publication Open Access Cytotoxic, genotoxic and apoptotic effects of Viburnum opulus on colon cancer cells: An in vitro study(2020-12-01T00:00:00Z) Guler, Eray Metin; Bozali, Kubra; Gulgec, Ahmet Sadik; KOÇYİĞİT, ABDÜRRAHİM; GÜLER, ERAY METİN; KOÇYİĞİT, ABDÜRRAHİM© 2020 De Gruyter. All rights reserved.Objective: Intake of various fruits is quite significant for maintaining the human body, due to their supply of useful constituents. V. opulus has been found to have outstanding antioxidant activity while showing a pro-oxidant effect at high doses. Due to this feature, V. opulus would be anticipated to have a healing impact on cancer treatment. In this study, it has been proposed to examine the cytotoxic, genotoxic, and apoptotic effects of V. opulus on human colorectal cancer cell. Method: Different concentrations of V. opulus methanolic extract (5-2000 μg/mL) were incubated for 24 h with colorectal cancer cell line (Lovo). The cell viability, intracellular reactive oxygen species (iROS), DNA damage, and apoptosis were measured after incubation. Results: The obtained results of this research demonstrate decreased cell viability and increased DNA damage, iROS, and apoptosis levels of V. opulus in Lovo cells in a concentration-dependent manner in the range of 14.88- 52.06%. There were strong positive relationships between apoptosis, genotoxicity, and cytotoxicity in V. opulus methanolic extract treated cancer cell line. Discussion: This in vitro research clearly demonstrated that V. opulus methanolic extract induces DNA damage, apoptosis, and cytotoxicity in a dose-dependent manner in cancer cells due to its pro-oxidant activity. Conclusion: Although in vitro results are favorable, in vivo and further studies are needed.Publication Metadata only Dialil Disülfit ve Dialil Trisülfit’in İnsan Prostat Kanser Hücreleri Üzerine Sitotoksik, Genotoksik ve Apoptotik Etkileri(2020-08-01T00:00:00Z) GÜLER, Eray Metin; KOÇYİĞİT, ABDÜRRAHİM; Kaleli, Hümeyra Nur; hira, hatice rabia; GÜLER, ERAY METİN; KOÇYİĞİT, ABDÜRRAHİM
