Abstract
Background: We aim to directly compare the feasibility and safety of extended pelvic lymph node dissection (PLND) during transperitoneal robotic-assisted radical prostatectomy (Tp-RARP) and extraperitoneal laparoscopic radical prostatectomy (Ep-LRP). Materials and Methods: We retrospectively identified the prospectively maintained database records of 162 patients diagnosed with prostate cancer (PC) who underwent Ep-LRP or Tp-RARP with extended PLND. Patients with risk of nodal metastases over 5% according to Briganti nomogram received extended PLND. All data analyzed in this study were based on the documentation in our PC database including age, body mass index, Charlson comorbidity index score, preoperative prostate-specific antigen, history of abdominal surgery, biopsy Gleason score, total operation time, postoperative pelvic drainage time, pathological results, lymph node yield (LNY), percentage lymph node involvement (%LNI), and perioperative complications. Patients were followed up for biochemical recurrence in the postoperative period. Results: Eighty-two of the 162 enrolled patients were in group 1 (Ep-LRP+PLND) and 80 were in group 2 (Tp-RARP+PLND). There were no statistically significant differences between the groups regarding preoperative demographics and clinical characteristics. The median LNY was 17 (range 8-27) and 17.5 (range 10-29) in groups 1 and 2, respectively, and no statistically significant difference was found. There was no significant difference between the groups in terms of biochemical recurrence-free survival with mean follow-up of 44.8 months after radical surgery. Conclusion: Our results support the view that extended PLND through the Ep-LRP approach is a feasible and safe procedure without compromising oncological efficacy compared with a similar template attempted during Tp-RARP. Clinical Trial Registration number is 01/21-2.

Abstract
PURPOSE We aim to document the feasibility, perioperative safety, and the 12-month efficacy of holmium laser enucleation of the prostate (HoLEP) within 1-3 weeks following transrectal ultrasound (TRUS)-guided prostate biopsy. METHODS Data of the patients who underwent HoLEP following TRUS-guided prostate biopsy between March 2017 and July 2020 were analyzed retrospectively. Patients were divided into 2 groups: group 1 had undergone HoLEP in the early period after TRUS-guided prostate biopsy, while group 2 patients were biopsy-naive ("control group"). All patients were assessed preoperatively by a physical examination with the digital rectal examination; time from biopsy to HoLEP; measurement of Qmax, postvoiding residual volume, and prostate volume by transabdominal ultrasonography; serum prostate-specific antigen level, the International Prostate Symptom Score (IPSS); the International Index of Erectile Function-5 questionnaire; and urine analysis. The patients were reevaluated at 3- and 12-month follow-up. Perioperative and postoperative complications were documented according to the modified Clavien-Dindo System. RESULTS Group 1 comprised 66 patients with a mean age of 67.3 ± 6.7 (range, 53-86) years, and group 2 comprised 114 patients with a mean age of 69.4 ± 9.4 (range, 36-95) years. The operation, enucleation, and morcellation efficiencies were not statistically significant between the groups. Preoperative Qmax and IPSS values were significantly improved after HoLEP surgery in the 3rd and 12th months in all patients. Our complication rates were similar in both groups. CONCLUSION High-powered HoLEP using 140 W energy within 1-3 weeks following TRUS-guided prostate biopsy is a feasible procedure with high enucleation efficiency, low perioperative morbidity, and excellent functional outcomes. A recent TRUS-guided prostate biopsy is not a contraindication to HoLEP.

Abstract
OBJECTIVE This study aimed to assess the perioperative and the 12-month efficacy and safety of 140 W high-powered holmium laser for enucleation of the prostate (HP-HoLEP) for the treatment of benign prostatic obstruction. MATERIAL AND METHODS The data of 540 patients who underwent HoLEP by a single surgeon were analyzed retrospectively. Preoperative evaluation included a physical examination with a digital rectal examination, measurement of maximum urinary flow rate (Qmax), postvoid residual volume (PVR) and prostate volume by transabdominal ultrasonography, serum prostate-specific antigen (PSA), international prostate symptom score (I-PSS) and international index of erectile function-5 (IIEF-5) questionnaires, and urine analysis. Morcellation, enucleation, and operation efficiencies were calculated with the resected weight divided by morcellation, enucleation, and operative times, respectively. The patients were reassessed at 1, 3, 6, and 12 months after surgery by I-PSS, IIEF-5, Qmax, PSA, and the occurrence of complications. RESULTS The mean operative time was 65.2±20.9 minutes. The mean enucleation time and efficiency were 53±15.1 minutes and 1.72±0.4 g/min, respectively. The mean morcellation time and efficiency were 12.3±15.1 minutes and 7.4±3.2 g/min respectively. Clavien grade 1 complications were observed in 102 (18.9%) patients, Clavien grade 2 complications in 20 (3.7%) patients, and Clavien grade 3b complications in 23 (5.4%) patients. I-PSS, Qmax, and IIEF-5 at postoperative 1, 3, 6, and 12 months were significantly better than baseline results. CONCLUSION Our study demonstrated that 140 W HP-HoLEP can be performed with high enucleation efficiency, low perioperative and postoperative complication rates, and excellent functional results.

Abstract
INTRODUCTION To compare the prostate removal speeds of 3 enucleation techniques and to evaluate how the operating times change depending on the prostate volume. METHODS Medical records of patients with 80-g or larger prostates who underwent holmium laser enucleation of the prostate (HoLEP), laparoscopic simple prostatectomy (LSP), or open prostatectomy (OP) due to medical treatment-resistant benign prostatic hyperplasia (BPH) were reviewed retrospectively. Patients were classified into 3 groups according to the surgical procedure. Age, BMI, prostate weights, total operation times, prostate removal speeds, hospitalization and catheterization days, complications, and improvements on functional outcomes in the 3rd month of follow-up were compared between groups. In addition, the association between prostate weight and total operation time was analyzed for each group. RESULTS HoLEP, LSP, and OP groups consisted of 60, 61, and 37 patients, respectively. While HoLEP was similar to OP in terms of prostate removal speed and total operation time, LSP was statistically slower and required more operation time than HoLEP and OP. There was a relationship between prostate weight and total operation time only in HoLEP. CONCLUSION LSP, one of the enucleation techniques in the treatment of large prostates, was slower and required more operation time than HoLEP and OP in terms of total operation time and prostate removal speed. HoLEP seems going to be the fastest candidate for the rapid removal of large prostates in the future.

Abstract
Abstract
Introduction/Objective
There is no reliable biomarker to predict the degree of fibrosis in CD. Quantification of C-mi has been used as a surrogate for enteric neural structures in Hirschsprung disease. The quantity of C-mi at the proximal margin may correlate with the degree of fibrosis in resected CD.
Methods
Ileocolonic resection cases for 20 CD and 3 trauma (control) were retrieved. Cases with severe mucosal inflammation at the margins were excluded. The proximal and distal margin sections were subjected to calretinin immunohistochemistry. Random mucosal images were captured from scanned slides (x200, JPEG), submucosa was edited out, and C-mi was calculated by image processing and analysis. rC-mi was defined as the mean C-mi of proximal margin normalized by that of distal margin. Cases with rC-mi less than the mean rC-mi + 2 SD of the controls were excluded. The maximum thicknesses of submucosa and muscularis propria were measured at the most stenotic site, microscopically. Pearson’s correlation test and Student’s t-test were performed to correlate the parameters and compare the means, respectively.
Results
A total of 216 images were captured (mean 9.3 images per case; range 7 to 10). The mean rC-mi of CD (1.26) was greater than the controls (mean 0.43) (p<0.05). The mean rC-mi + 2 SD of the control group was 0.91, thus 2 CD cases were excluded from final analysis. The rC-mi of CD showed an inverse relationship with maximum submucosal thickness (mean 3.4 mm, range 0.2 to 5.9) at the site of stenosis (r=-0.47; p<0.05), but not with muscularis propria.
Conclusion
The rC-mi of CD was inversely correlated with submucosal fibrosis. Altered stromal integrity, impaired intercellular signaling, progressive reduction and loss of telocytes induced by submucosal fibrosis may reduce the regenerative capacity of enteric neural structures in CD. Therefore, a decreasing trend in rC-mi may predict fibrosis progression in CD.

Abstract
Abstract
Introduction/Objective
A subset of patients with an established diagnosis of UC develops signs of CD (de novo CD) following IPAA. While the etiology and risk factors of de novo CD remain largely unknown, preliminary studies have shown controversial results regarding family history of inflammatory bowel disease (IBD) and smoking history.
Methods
Patients that underwent IPAA for UC, with at least 1 year of follow-up, were identified (n=161; 1996 to 2018). We retrospectively reviewed the electronic medical records. Patients that were diagnosed with de novo CD during the follow-up period were further identified. Smoking history and family history of IBD were evaluated. Chi square test was performed to compare the frequencies. Odds ratio (OR) and 95% confidence intervals (CIs) were estimated by logistic regression model. P<0.05 was considered statistically significant.
Results
29 de novo CD were identified. At the time of proctocolectomy, the family history of IBD and smoking history was documented in 152 UC patients including 27 that subsequently developed de novo CD. 23 of 152 had a family history of IBD (12 UC, 9 CD and 2 IBD, NOS). 19/129 (14.7%) UC patients without a family history of any type of IBD, 4/9 (44.4%) with a family history of CD, and 4/12 (33.3%) with a family history of UC developed de novo CD. Patients with a family history of CD were more likely to develop de novo CD post IPAA than those without a family history of any type of IBD (OR 4.63, 95% CI 1.14-18.82, p=0.03). Family history of UC did not correlate with development of de novo CD (OR 2.90; 95% CI 0.79-10.57, p=0.108). At the time of proctocoletomy, 11 were current smokers, 25 were former smokers, and 116 never smoked. In de novo CD group, there were 4/27 (14.8 %) former smokers and 23/27 (85.2 %) never smokers. No de novo CD patient was current smoker. In the UC group that remained as UC following IPAA, 11/125 (8.8%) were current smokers, 21/125 (16.8 %) former smokers, and 93/125 (74.4 %) were never smokers. Current smoking status was not associated with development of de novo CD (p = 0.214).
Conclusion
Family history of CD may be a risk factor for developing de novo CD following IPAA for UC. Current smoking status was not associated with development of de novo CD following IPAA for UC.

Abstract
The study was conducted to evaluate effects of different dietary oils on egg quality and reproductive performance in rainbow trout. Broodfish (≈ 870 g) were fed four iso-nitrogenous and iso-lipidic diets differing in lipid sources: fish oil (FO), linseed oil (LO) and sesame oil (SO) as well as a commercial trout diet (CD) for about 5 months prior to spawning. Growth performance did not differ among the trout in the treatment groups. Mean diameter, volume and weight of eggs did not differ among the dietary treatments. Absolute fecundity, relative fecundity and gonadosomatic index were not affected by dietary treatment. A sub-set of eggs from females fed the experimental diets were fertilized to assess the reproductive performance of broodfish. When diets were fed, devoid of fish oil, fertilization rates were 89.2 ± 5.8 and 92.1 ± 4.9 %, eyeing rates were 87.3 ± 5.3 and 84.1 ± 4.4 % and hatching rates were 81.2 ± 4.3 and 78.3 ± 3.4 % in LO and SO fed fish, respectively. Fatty acid content of the eggs from broodstocks with a different nutritional history was affected by the dietary lipid sources. Eicosapentaenoic acid (EPA), arachidonic acid (ARA), and docosahexaenoic acid (DHA) concentrations in females fed vegetable oil based diets were greater than the dietary concentrations. Overall, results from the present study indicate there can be inclusion of LO or SO as dietary lipid sources without compromising egg quality and reproductive performance. Furthermore, there is efficient bioconversion of 18C fatty acids to 20-22 C fatty acids in rainbow trout.

Abstract
BACKGROUND Different techniques for laparoscopic adrenalectomy have been proposed with the lateral transperitoneal approach and posterior retroperitoneal approach being the two more frequently minimally invasive surgeries in most of the clinics. There are no sufficient studies in which the results of lateral transperitoneal and posterior retroperitoneal approaches in synchronous bilateral laparoscopic adrenalectomy have been compared. In the current study, we aimed to report our multicenter results of the lateral transperitoneal and posterior retroperitoneal synchronous bilateral laparoscopic adrenalectomy experience in patients who had different bilateral adrenal pathologies and to compare the outcomes of these two different operative procedures. METHODS Between 2012 and 2018, a total of 52 patients with a mean age of 43.5 years underwent simultaneous bilateral laparoscopic adrenalectomy at 6 different centers. Twenty-seven and 25 patients underwent bilateral lateral transperitoneal and posterior retroperitoneal laparoscopic adrenalectomy, respectively. Patients' age, gender, body max index, operative indications, mass size, operation time, blood loss, length of hospitalization, intraoperative and postoperative complications and pathology reports were analyzed. RESULTS Synchronous bilateral transperitoneal group was younger than synchronous posterior retroperitoneal group (37 years vs. 50.4 years.) (p: 0.001). Posterior retroperitoneal group had significantly decreased operating time and less blood loss than transperitoneal group. No significant difference was found with regard to postoperative hospital stay, perioperative and postoperative complications between two groups. Majority of the histopathological results were adrenal hyperplasia associated with Cushing's disease (61.5%). Less frequent pathological results were adrenal adenoma and pheochromocytoma (15.4% and 13.5%, respectively). During the follow-up period, no recurrence or disease-related mortality was observed in the patients. CONCLUSION Our results shows that shorter operative time and less bleeding can be achieved with posterior retroperitoneal approach in synchronous bilateral laparoscopic adrenalectomy. In our series, intraoperative and postoperative complication rates were similar between both surgical approaches.

Abstract
AIM The aim of this study is to demonstrate whether fullerenol C60 protects renal injury in sevoflurane‑administered rats. METHOD Rats (n: 24) were randomly divided into four groups: Control (Group C), Fullerenol C60 (Group F), Sevoflurane (Group S), Fullerenol C60-Sevoflurane (Group FS). Thirty minutes before the procedure, Fullerenol C60, 100 mg/kg, was administered intraperitoneally. Sevoflurane (2.3 %) was applied for 3 hours to rats in S and FS groups. Biochemical and histopathological parameters were analyzed in renal tissue samples. Kruskal-Wallis and Mann-Whitney U tests were used in statistical analyzes. RESULTS Malondialdehyde (MDA) level and catalase (CAT) enzyme activity in Group S were significantly higher than that in all other groups. Paraoxanase (PON) enzyme activity in Group S was significantly lower than in Groups C and FS. The histopathological examination showed that vascular vacuolization and hypertrophy (VVH) and lymphocyte infiltration (LI) were significantly higher in the Group S compared to the Group C. CONCLUSION Renal histopathology revealed that the administration of Fullerenol C60 prior to sevoflurane inhalation reduced oxidative stress and partially corrected the damage caused by anesthesia. We concluded that Fullerenol C60 has a renal protective effect in rats when administered before sevoflurane anesthesia (Tab. 2, Fig. 4, Ref. 40).

Abstract
Aims: Coronary computed tomography angiography is increasingly employed in the emergency department for suspected acute coronary syndrome patients. The HEART score has been proposed for initial risk stratification in these patients. The aim of this study was to investigate the diagnostic value and efficiency of the HEART score before coronary computed tomography angiography. Methods and results: We included patients suspected of acute coronary syndrome who underwent coronary computed tomography angiography in the emergency department. Based on the HEART score, patients were stratified as low-risk (HEART≤3), intermediate-risk (HEART4–6) and high-risk (HEART≥7). We assessed coronary computed tomography angiography for the presence of significant coronary artery disease (>50% stenosis). The primary outcome, the level of major adverse cardiac events, was a composite endpoint of all-cause mortality, acute coronary syndrome or coronary revascularisation within 30 days. The study population consisted of 340 patients (mean age: 55.6±10.1 years, 44.7% women), major adverse cardiac events occurred in 45 (13.2%) patients. The incidence of major adverse cardiac events in patients stratified as low-risk (35.0%), intermediate-risk (56.8%) and high-risk (8.2%) was 3.4%, 12.4% and 60.7%, respectively. All four low-risk patients with major adverse cardiac events had a HEART score of three. An algorithm where coronary computed tomography angiography is reserved for patients with HEART 3–6 resulted in a sensitivity of 97.8%, specificity of 84.1%, negative predictive value of 99.6% and positive predictive value of 48.4%, while reducing the need for coronary computed tomography angiography by 22% (n=75). Conclusion: The predictive value of coronary computed tomography angiography for 30-day major adverse cardiac events in suspected acute coronary syndrome patients is good, and reserving coronary computed tomography angiography for HEART score 3–6 patients reduces the number of needed coronary computed tomography angiograms without affecting diagnostic accuracy.

Abstract
OBJECTIVE In this study we aimed to evaluate the effect of dexmedetomidine and thymoquinone on erythrocyte deformability in lower limb ischaemia-reperfusion (IR) injury in streptozotocin-induced diabetic rats. MATERIAL AND METHODS Thirty Wistar albino rats were equally divided into 5 groups (n = 6); randomized control group (Group C), diabetes control group (Group DC), DIR group (Group DIR), DIR group with thymoquinone 25 mg.kg‒1 intraperitoneally (Group DIRT) and Group DIR with dexmedetomidine 100 µg.kg‒1 intraperitoneally (Group DIRD). Erythrocyte packs were prepared from heparinized blood samples and deformability measurements were performed. RESULTS IR significantly increased the relative resistance, a marker of erythrocyte deformability when compared to control group (p < 0.05). There were significant differences among the groups in comparisons with ANOVA test (p < 0.0001). Comparisons of the groups DIRD and DIRT revealed similar results (p = 0.824). The values of Group DIR were significantly higher than those of the control, DC, DIRD and DIRT groups (p < 0.0001, p = 0.001, p = 0.004, p = 0.002, respectively). The values of the DC, DIR, DIRD and DIRT groups were significantly higher than those of the control group (p < 0.0001, all). CONCLUSION Erythrocyte deformability may cause more problems in microcirculation. Dexmedetomidine and thymoquinone may be useful in reducing the adverse effects of this type of injury (Fig. 1, Ref. 41).

Background Ultrasound-accelerated catheter-directed thrombolysis (UCT) increases the invasion of thrombolytic agent into the thrombus using ultrasonic energy, provides less infusion of thrombolytic agent, reduces complication, and post-thrombotic syndrome (PTS) development rates. For these reasons, this procedure is a promising method for the treatment of deep vein thrombosis (DVT). Materials and Methods Patients diagnosed with DVT by ultrasonography (USG) who underwent UCT between May 2013 and August 2014 at Gazi University Hospital Cardiovascular Surgery Clinic were included in the study. The demographic characteristics and postoperative acute and long-term patency rates and deep venous insufficiency rates were evaluated retrospectively to determine the efficacy of the UCT procedure. Patients were classified as acute, subacute, and chronical DVT according to the onset of complaints. The efficacy of the UCT procedure was assessed by Doppler USG performed 6 months and 2 years after the procedure, and patients were re-evaluated for deep venous insufficiency and thrombus findings to determine the relationship between UCT procedure and deep venous insufficiency. Results In acute phase, 57.1% (n = 8) complete and 35.7% (n = 5) partial openings were obtained. No complete patency was obtained in any of the subacute patients. However, partial openness rate was 60%. In patients admitted during the chronic period, complete patency was obtained in 20% (n = 8) and partial openings in 60% (n = 3). Although thrombolysis success was not considered as statistically significant, the success rate was numerically higher in the acute phase. Conclusion As a result, UCT applications provide thrombolysis especially in acute deep vein thrombosis, preventing deep venous insufficiency and especially post-thrombotic syndrome formation. UCT prevents bleeding complications by keeping thrombolytic amount low and can be used as an endovascular method of high safety in patient population with high bleeding complications such as patients with malignancies.

Abstract
Aim: We aimed to investigate the changes in respiratory mechanics in adult patients undergoing open heart surgery (OHS) while using volume-controlled auto-flow (VCAF) ventilation mode. Materials and Methods: After obtaining ethics committee's approval and informed consent, 30 patients (17 males and 13 females; mean age: 57.3 ± 17.0 years; mean weight; 74.9 ± 13.6 kg) scheduled for OHS were enrolled. Mechanical ventilation was carried out using VCAF mode (VT: 5–8 mL/kg, I/E: 1/2, 10 ± 2 fr/min). Values of dynamic compliance (Cdyn) and resistance (R) were obtained at six time points (TPs). Normally distributed variables were analyzed with repeated measure of analysis of variance and Bonferroni tests. For abnormally distributed variables, Friedman variance analysis and Wilcoxon signed-rank tests were used. Values were expressed as mean ± standard deviation. P value <0.05 was considered significant. Results: Cdyn (mL/mbar) and R (mbar/L/s) values were as follows – (1) before sternotomy (S): 49.9 ± 17.1 and 7.8 ± 3.6; (2) after S: 56.7 ± 18.3 and 7.1 ± 3.7; (3) after S and after sternal retractor placement: 48.7 ± 16.1 and 8.3 ± 4.4; (4) after weaning from cardiopulmonary bypass and following decannulation while retractor was in place: 49.6 ± 16.5 and 8.1 ± 4.0; (5) after retractor removal: 56.5 ± 19.6 and 7.4 ± 3.7; and (6) after sternal closure: 43.1 ± 14.2 and 9.6 ± 9.1, respectively. Significant differences were observed in Cdyn and R between; first and second TPs, second and third TPs, fourth and fifth TPs, and fifth and sixth TPs. Also, significant difference in Cdyn was found between first and sixth TPs, but it was not found in R. Conclusion: Cdyn decreases, but R remains the same in cardiac surgical patients when mechanical ventilation is performed with VCAF ventilation mode. Additionally, Cdyn is negatively affected by the presence of sternal retractor and the sternal closure in OHS.

Abstract
Aims: The purpose of this study was to determine (a) the ability of serial high-sensitivity cardiac troponin T measurements to rule out acute myocardial infarction and (b) the ability of a single high baseline high-sensitivity cardiac troponin T measurement to rule in acute myocardial infarction in patients presenting to the emergency department with acute chest pain. Methods and results: Embase, Medline, Cochrane, Web of Science and Google scholar were searched for prospective cohort studies that evaluated parameters of diagnostic accuracy of serial high-sensitivity cardiac troponin T to rule out acute myocardial infarction and a single baseline high-sensitivity cardiac troponin T value>50 ng/l to rule in acute myocardial infarction. The search yielded 21 studies for the systematic review, of which 14 were included in the meta-analysis, with a total of 11,929 patients and an overall prevalence of acute myocardial infarction of 13.0%. For rule-out, six studies presented the sensitivity of serial measurements <14 ng/l. This cut-off classified 60.1% of patients as rule-out and the summary sensitivity was 96.7% (95% confidence interval: 92.3–99.3). Three studies presented the sensitivity of a one-hour algorithm with a baseline high-sensitivity cardiac troponin T value<12 ng/l and delta 1 hour <3 ng/l. This algorithm classified 60.2% of patients as rule-out and the summary sensitivity was 98.9% (96.4–100). For rule-in, six studies reported the specificity of baseline high-sensitivity cardiac troponin T value>50 ng/l. The summary specificity was 94.6% (91.5–97.1). Conclusion: Serial high-sensitivity cardiac troponin T measurement strategies to rule out acute myocardial infarction perform well, and a single baseline high-sensitivity cardiac troponin T value>50 ng/l to rule in acute myocardial infarction has a high specificity.

Abstract
BACKGROUND Cerium oxide is the oxide form of cerium, which has protective effects in ischemia reperfusion (I/R) injury. The purpose of our study was to look into the effects of this rare-earth metal on erythrocyte deformability in rat lower extremity I/R injury model. MATERIALS AND METHODS We used 24 Wistar albino rats as subjects in our study. They were divided into 4 groups; randomized control group (group C; n = 6), cerium oxide group 0.5 mg.kg-1, intraperitoneal (group CO; n = 6), I/R group (group I/R; n = 6) and I/R group with cerium oxide 0.5 mg.kg-1 intraperitoneally (group I/R-CO; n = 6). Erythrocyte packs were prepared from heparinized blood samples and deformability measurements were performed. RESULTS We obtained similar results from the control and I/R-CO groups (p = 0.158). The results in I/R group were evidently higher than those of the control, CO, and IR-CO groups (p < 0.0001, p < 0.0001, p = 0.001, respectively). CONCLUSION We detected unfavorable effects of I/R on erythrocyte deformability, which may impair blood flow and hence tissue perfusion in infrarenal rat aorta. We also found that cerium oxide had beneficial effects by reversing undesirable effects of I/R. Further studies with larger volume are required to support our promising results (Fig. 1, Ref. 24).

Abstract
AIM We want to investigate the protective effects of apelin-13 on myocardial ischemia reperfusion (I/R) injury. MATERIAL AND METHODS 30 Wistar Albino rat were divided into 5 groups (n:6), namely control group (C), diabetes group (D), diabetes+apelin-13 group (DA), diabetes+I/R group (DIR) and diabetes I/R+apelin-13 group (DIR-A). Rats were subjected to 30‑min ischemia and 90‑min reperfusion. Biochemical and histopathological parameters were measured. RESULTS Caspase-3 enzyme activity was significantly higher in the DIR group than in the C, DA, and DIR-A groups. The intensity of caspase 3 enzyme activity was significantly higher in the I/R group than in all other groups. Inflammation and vascular dilatation were found significantly higher in the DIR group than in all other groups. Congestion was significantly higher in the DIR group than in the C and D groups. TOS enzyme activity was significantly higher in the DIR group than in the C, DA and DIR-A groups. TAS enzyme activity was significantly lower in the DIR group than in the C and DIR-A groups. CONCLUSION We believe that the protective effects of apelin-13 in ischemia-reperfusion injury and its use indications can be demonstrated in detail as long as the findings we have reached in our study are supported by other studies (Tab. 2, Fig. 10, Ref. 43).
