Öğe Ameliorative effects of crocin on tartrazine dye-induced pancreatic adverse effects: a biochemical and histological study(Springer Heidelberg, 2021) Erdemli, Zeynep; Altinoz, Eyup; Erdemli, Mehmet Erman; Gul, Mehmet; Gozukara, Harika; Gul, SemirThe present study aimed to analyze the impact of tartrazine (T) and crocin (Cr) applications on the pancreas tissues of the Wistar rats. A total of 40 Wistar rats were randomly divided into 4 groups with 10 rats in each group, including the Control, T, Cr, and T + Cr groups. After 3 weeks of application, the pancreatic tissues of the rats were removed under anesthesia and rat blood samples were obtained. Tissues were analyzed with biochemical and histopathological methods. It was determined that T administration increased malondialdehyde (MDA), total oxidant status (TOS), oxidative stress index (OSI), glucose, triglyceride, LDL, VLDL, and total cholesterol levels. However, it decreased reduced glutathione (GSH), total antioxidant status (TAS), superoxide dismutase (SOD), catalase (CAT), and HDL levels when compared with the other groups. It was observed that Cr administration significantly increased GSH, SOD, CAT, TAS, and HDL levels when compared with the control group. In the T group, histopathological changes were observed in pancreatic tissue, leading to damages in exocrine pancreas and islets of Langerhans and increased caspase-3 immunoreactivity (p <= 0.001). Co-administration of Cr and T brought the biochemical and histopathological findings closer to the control group levels. The administration of T induced damage in the pancreas with the administered dose and frequency. Cr can increase the antioxidant capacity in pancreas tissue. Co-administration of T and Cr contributed to the reduction of the toxic effects induced by T. It could be suggested that Cr administration ameliorated T toxicity.Öğe Association between latent toxoplasmosis and clinical course of schizophrenia - continuous course of the disease is characteristic for Toxoplasma gondii-infected patients(Folia Parasitologica, 2015) Celik, Tuncay; Kartalci, Sukru; Aytas, Ozgur; Akarsu, Gulay Aral; Gozukara, Harika; Unal, SuheylaThe aim of the present study was to investigate the association between various clinical aspects of schizophrenia and seropositivity against Toxoplasma gondii (Nicolle et Manceaux, 1908). We selected 94 patients with schizophrenia and investigated the seropositivity rate for anti-T. gondii IgG antibodies by ELISA. Clinical parameters of schizophrenic patients such as illness type and status, clinical course, awareness of the illness and need for electroconvulsive therapy (ECT) were compared with their serological status. Anti-T. gondii IgG antibodies were detected in 43 (46%) of schizophrenic patients. Chronic patients had a rate of 34 (72%) seropositivity, whereas 9 (22%) of the patients with partial remission showed evidence of latent toxoplasmosis. Of continuous patients, 35 (81%) were found to be seropositive and this rate was significantly more than in the other groups. The rate of latent toxoplasmosis was detected significantly higher in patients who lack awareness of schizophrenia (36, i.e. 72%) than the patients who were aware of their illnesses (7, i.e. 16%). Anti-T. gondii IgG antibodies were detected in 38 (70%) of ECT performed patients while this percentage was 13% in the ones who had never been treated with ECT. This difference was also statistically significant. We showed that Toxoplasma-infected subjects had 15x higher probability of having continuous course of disease than Toxoplasma-free subjects. Our results put forth the possibility of latent toxoplasmosis to have a negative impact on the course of schizophrenia and treatment response of schizophrenic patients.Öğe Association of eNOS Gene Polymorphisms G894T and T-786C with Risk of Hepatorenal Syndrome(Hindawi Ltd, 2016) Seckin, Yuksel; Yigit, Ali; Yesilada, Elif; Gulbay, Gonca; Cagin, Yasir Furkan; Gozukara, Harika; Bilgic, YilmazBackground. There are no studies investigating the relationship between endothelial nitric oxide synthase (eNOS) gene polymorphisms and hepatorenal syndrome (HRS). Aim. The purpose of this study is to elucidate whether eNOS gene polymorphisms (G894T and T-786C) play a role in the development of type-2 HRS. Methods. This study was carried out in a group of 92 patients with cirrhosis (44 patients with type-2 HRS and 48 without HRS) and 50 healthy controls. Polymorphisms were determined by polymerase chain reaction (PCR) and melting curve analysis. Results. We did not find any significant difference in allele and genotype distributions of the eNOS -T-786C polymorphism among the groups (p = 0.440). However, the frequency of GT (40.9%) and TT (13.6%) genotypes and mutant allele T (34.1%) for the eNOS G894T polymorphism were significantly higher (p < 0.001 and p < 0.001, resp.) in the HRS group than in both the stable cirrhosis (14.6%, 4.2%, and 11.5%, resp.) and the control (22.0%, 2.0%, and 13.0%, resp.) groups. Conclusion. The occurrence of mutant genotypes (GT/TT) and mutant allele T in eNOS -G894T polymorphisms should be considered as a potential risk factor in cirrhotic patients with HRS.Öğe BURDEN OF HEADACHE DISORDERS AT ATTENTION DEFICIT HYPERACTIVITY DIAGNOSED CHILDREN AND THEIR PARENTS(Sage Publications Ltd, 2017) Kucuk, Meryem O.; Guler, Gulen; Tufan, Evren; Yalin, Osman Ozgur; Gozukara, Harika; Ozge, Aynur; Toros, Fevziye[Abstract Not Available]Öğe Comparison of Antiaging Effects on Rat Skin of Cog Thread and Poly-L-Lactic Acid Thread(Lippincott Williams & Wilkins, 2019) Kapicioglu, Yelda; Gul, Mehmet; Sarac, Gulbahar; Yigitcan, Birgul; Gozukara, HarikaBACKGROUND Polydioxanone Cog thread and poly-L-lactic acid (PLLA) thread have been used clinically for lifting and antiaging purposes. However, the histological changes in tissue and the efficacy of these 2 different types of thread have not been compared. OBJECTIVE This study used hematoxylin and eosin (H&E) staining, Masson's trichrome staining, and electron microscopy (EM) to compare the results associated with the use of Cog thread and PLLA thread in rat skin. METHODS Thirty female rats were divided into 3 groups of 10 rats each: a control group; a Cog group; and a PLLA group. Biopsy specimens obtained at 1, 3, and 6 months were examined using H&E, MT, and EM. RESULTS Although significant increases were observed in dermal thickness and the numbers of fibroblasts in the PLLA group compared with the control group within the first month (p: .019), there were no significant differences between the Cog and control groups during this period (p: .245). Dermal thickness (p: .002) and numbers of fibroblasts (p: .001) were similar in samples obtained from the PLLA and Cog groups at 3 and 6 months, and both groups showed significantly improved outcomes compared with the control group. CONCLUSION Poly-L-lactic acid and Cog sutures were effective in facial rejuvenation; both increased dermis thickness and stimulated collagen production.Öğe Early therapeutic plasma exchange may improve treatment outcomes in severe acute toxic Hepatitis(Pergamon-Elsevier Science Ltd, 2021) Berber, Ilhami; Cagin, Yasir Furkan; Erdogan, Mehmet Ali; Ataman, Engin; Gozukara, Harika; Erkurt, Mehmet Ali; Yildirim, OguzhanBackground and objectives: Acute toxic hepatitis can result in a different clinical course from a completely curable disease to subacute hepatitis, chronic hepatitis, and fulminant hepatitis failure, which is quite mortal. For this purpose, therapeutic plasma exchange (TPE) can be used for improving treatment outcomes by reducing the harmful substances caused with and/or without liver function in acute toxic hepatitis. We aimed to evaluate treatment outcomes in severe acute toxic hepatitis patients who applied early TPE procedure. Materials and Methods: A total of 335 patients who received TPE between 2010-2021 were retrospectively screened and 59 (male/female, 30/29; min/max-age, 22-84) patients with acute toxic hepatitis who underwent TPE in the first 24 h were included in the study. TPE was performed in patients who had high total bilirubin level (>10 mg/dL). Laboratory parameters of the patients before and after the TPE procedure, number of patients developed complications of acute toxic hepatitis and mortality rates were evaluated for effectiveness of TPE. Results: Acute toxic hepatitis was associated with hepatotoxic drugs in 44 (74.5 %), herbal medication 6 (10.2 %), mushroom poisoning 6 (10.2 %) and with substance abuse 3 (5.1 %) in patients. When the patients were compared based on INR, liver function tests, ammonia, lactate and Model For End-Stage Liver Disease (MELD) score at baseline, 48 h after TPE (independently of TPE number) and before final state a statistically significant decrease was observed in all parameters (p < 0.05). Fifty three (90 %) of patients improved without complications, the remaining 6 (10 %) patients were diagnosed with fulminant hepatitis. All these remaining patients died before liver transplantation (LTx) could be performed. Conclusion: TPE is a safe, tolerable therapy option and early TPE may improve treatment outcomes in severe acute toxic hepatitis.Öğe The effect of the intercondylar notch width index on anterior cruciate ligament injuries : A study on groups with unilateral and bilateral ACL injury(Acta Medica Belgica, 2015) Gormeli, Cemile Ayse; Gormeli, Gokay; Ozturk, Burak Yagmur; Ozdemir, Zeynep; Kahraman, Aysegul Sagir; Yildirim, Okan; Gozukara, HarikaBackground : To evaluate the relationship of the intercondylar notch width with unilateral and bilateral ACL injury by using MR images. Materials and Methods : The intercondylar notch width index was measured on the MR images of 18 patients with a bilateral ACL injury, 38 patients with a unilateral ACL injury and 53 healthy subjects with a normal ACL and the results of all groups were compared with each other. Results : The mean NWI values were 0,227 (+/- 0.008) in bilateral injured; 0,245 (+/- 0.009) in unilateral injured and 0,272 (+/- 0.01) in control groups and 0,251(+/- 0.01) in unaffected side of the unilateral group. There were statistically significant differences in intercondylar notch width index (NWI) values between all groups and there was a significant difference between the affected and the unaffected sides in group with unilateral ACL injury. A cutoff value of 0.25 for NWI gave an odds ratio of 26.5 for bilateral and 3.23 for unilateral ACL injuries. Conclusions : The finding that NWI is significantly narrowed in patients with bilateral and unilateral ACL tears compared with the healthy controls suggest a relationship between a narrow NWI and an increased risk of ACL injury. The patients with a narrow NWI should also be screened contralaterally for assessment of ACL injury risk on the other knee. So, specialized training programmes for the people with narrow NWI can be prepared for preventing ACL injuries.Öğe EVALUATION OF PSYCHIATRIST'S COMMUNICATION WITH PSYCHOSIS PATIENTS(Univ Chile, Centro Interdisciplinario Estudios Bioetica, 2022) Karatas, Mehmet; Kartalci, Sukru; Selcuk, Engin Burak; Yetis, Hakan; Karatas, Turgay; Gozukara, HarikaEvaluation of the physician-patient relationship is very important in determining priorities in medical practice and medicine. For this purpose, in this study the psychiatrist's communication with psychotic patients as a sensitive group was evaluated. A questionnaire was administered to 210 patients in a psychiatric clinic of Inonu University Hospital in Turkey to determine how the examination is performed in the facility for outpatients in the psychosis unit. According to the study conducted, it was observed that the evaluation score of the psychiatrist's communication with psychotic patients increased positively with increasing consultation duration. Our work is particularly noteworthy because it deals with a sensitive area, such as a group of psychiatric patients. The scores were obtained based on data from the evaluation of the questionnaires, which showed that the communication between the psychiatrist and the psychotic patient was conducted in a sensitive and careful manner, and without ethical problems.Öğe HBV viral load and tumor and non-tumor factors in patients with HBV-associated HCC(Kare Publ, 2024) Ataman, Engin; Harputluoglu, Murat; Carr, Brian Irving; Gozukara, Harika; Ince, Volkan; Yilmaz, SezaiBackground and Aim: Several tumor and non-tumor factors affect the prognosis of hepatocellular carcinoma (HCC) patients. This study aimed to investigate the effects of hepatitis B virus (HBV) viral load on tumor and non-tumor factors in patients with HBV-associated HCC. Materials and Methods: Patients with hepatitis B and HCC who presented Transplantation Institute, were included in our study. Patients were divided into two groups according to the presence or absence of HBV-DNA, and it was determined whether there were differences between these two groups with respect to tumor and non-tumor parameters. Results: Comparison of serum alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), hepatitis B surface antigen (HBsAg), and C-reactive protein (CRP) levels between HBV-DNA negative and positive patients showed significant differences (respectively p<0.01, p<0.01, p<0.05, and p<0.05). A major finding was a very significant difference between the two patient groups in terms of portal vein invasion (PVI) and venous invasion (p<0.001 and p<0.01, respectively). However, there was no significant difference in metastasis or lymph node involvement between HBV-DNA negative and positive patients. Conclusion: Our findings suggest that HBV viral load plays an important role in PVI in HCC patients, and there is a significant relationship between HBV viral load and inflammation.Öğe Histopathologic and Electron Microscopic Investigation of the Effects of Parenteral Nutrition Combined with Starvation on Kidney Tissue of Rabbits(Aves, 2021) Gurunluoglu, Semra; Gul, Mehmet; Gozukara, HarikaObjective: To conduct a histopathologic examination of the effects of a combination of parenteral nutrition (PN) and starvation on rabbits' kidney tissue using light microscopy and transmission electron microscopy. Methods: Four groups consisting of equal numbers of adult female and male New Zealand rabbits were formed (n = 14 each). Rabbits in the PN + oral feeding group were provided with half of their daily caloric needs from rabbit feed and the other half through PN. Rabbits in the PN + starvation group received a full dose of PN daily and received no feed. Rabbits in the half-starvation group were provided with rabbit feed covering only half their daily caloric needs. Rabbits in the control group were provided with all their caloric needs from rabbit feed. After 10 days, all the rabbits were weighed, anesthetized, and euthanized, and their kidney tissue samples were collected. Histopathologic examination was performed by a surgical pathologist blinded to the experimental groups. Results: The kidney tissue samples of rabbits in the PN + starvation group showed mild tubular dilatation, mild tubular degeneration, moderate renal inflammation, mild interstitial fibrosis, and increased apoptosis. The destructive effects were considerably milder in the PN + oral feeding group. Conclusion: PN combined with starvation can cause devastating damage to the kidneys. The damage can be minimized by combining PN with enteral nutrition.Öğe The Novel Synthesized Pyridazinone Derivates Had the Antiproliferative and Apoptotic Effects in SHSY5Y and HEP3B Cancer Cell Line(Bentham Science Publ Ltd, 2018) Ciftci, Osman; Ozdemir, Zeynep; Acar, Ceren; Sozen, Mert; Basak-Turkmen, Nese; Ayhan, Idris; Gozukara, HarikaBackground: Brain cancer (neuroblastoma) and liver cancer (hepatocellular carcinoma) are common cancer types among others worldwide which do not have a radical treatment and cure. Objective: In the current study, five novel pyridazinone derivates bearing benzelhydrazone moiety at second position were synthesized and evaluated for their cytotoxic activity against neuroblastoma and hepatocellular carcinoma (SHSY5Y and HEP3B) and human fibroblast (HF) cell lines. The aim of the current study is to identify antiproliferative activity of five novel pyridazinone derivates against neuroblastoma and hepatocellular carcinoma (SHSY5Y and HEP3B) and human fibroblast (HF) cell lines. Method: The compounds were synthesized by the reacting 6-[4-(phenyl/4-chlorophenyl)piperazine-1yl]-3(2H)-pyridazinone-2-yl acetohydrazide with benzaldehyde in ethanol. The in vitro antiproliferative activities were determined with MTT assay. Bax, Bcl-2 and Casp3 gene expression levels were detected with RT-PCR analyses. Results: The lowest IC50 was observed for compound 4 in SHSY5Y and HEP3B cells. Apoptosis increased in cancer cells which was shown by changes inBax, Bcl-2 and Casp3 gene expression levels with 1-5 compound therapy. Conclusion: Novel pyridazinone derivates might be promising agents as new chemotherapeutic candidates in brain and liver cancer.Öğe Outcome of transtibial AperFix system in anterior cruciate ligament injuries(Springer Heidelberg, 2015) Gormeli, Gokay; Gormeli, C. Ayse; Karakaplan, Mustafa; Korkmaz, M. Fatih; Dilicikik, Ugur; Gozukara, HarikaBackground: The anterior cruciate ligament (ACL) is one of the major stabilizing factor of the knee that resist anterior translation, valgus and varus forces. ACL is the most commonly ruptured ligament of the knee. The graft fixation to bone is considered to be the weakest link of the reconstruction. According to the parallel forces to the tibial drill hole and the quality of tibial metaphyseal bone is inferior to femoral bone stock, graft fixation to the tibia is more difficult to secure. AperFix system (Cayenne Medical, Inc., Scottsdale, Arizona, USA) which consists femoral and tibial component that includes bioinert polymer polyetheretherketone (PEEK) is one of the new choice for ACL reconstruction surgery. aim of this study was to assess the clinical outcomes and fixation durability of the AperFix (Cayenne Madical, Inc., Scottsdale, Arizona, USA) system and to determine the effect of patient's age in arthroscopic reconstruction of the anterior cruciate ligament. Materials and Methods: Patients with symptomatic anterior cruciate ligament rupture underwent arthroscopic reconstruction. Patients were evaluated in terms of range of motion (ROM) values; Lysholm, Cincinati and Tegner activity scales; laxity testing and complications. Femoral tunnel widening was assessed by computer tomography scans. Early postoperative and last followup radiographs were compared. Results: Fifty one patients were evaluated with mean followup of 29 months (range 25-34 months). Mean age at the surgery was 26.5 +/- 7.2 years. Lysholm, Cincinati and Tegner activity scales were significantly higher from preoperative scores (Lysholm scores: Preoperative: 51.4 +/- 17.2, postoperative: 88.6 +/- 7.7 [P < 0.001]; Tegner activity scores: Preoperative 3.3 +/- 1.38, postoperative: 5.3 +/- 1.6 [P < 0.001]; Cincinati scores: Preoperative: 44.3 +/- 17, postoperative: 81.3 +/- 13.9 [P < 0.001]). The mean femoral tunnel diameter increased signifi cantly from 9.94 +/- 0.79 mm postoperatively to 10.79 +/- 0.95 mm (P < 0.05). The mean ROM deficit (involved vs. contra knee) was -7.2 +/- 16 (P < 0.001). There was no signifi cant difference for knee score, ROM defi cits (< 30 years: -7.3 +/- 15 and > 30 years -7.06 +/- 19) and femoral tunnel enlargement (< 30 years: 0.83 +/- 0.52 and > 30 years 0.87 +/- 0.43) of the patients with below and above 30 year. There was no signifi cant difference for knee scores and femoral tunnel enlargement between patients with meniscal injuries and don't have meniscus lesions. Conclusion: The AperFix system gives satisfactory clinical and radiological results with low complication rate. However, long term clinical and radiological results are needed to decide the ideal anterior cruciate ligament reconstruction method.
