Abstract
BACKGROUND A fine-tuned pro-inflammatory and anti-inflammatory balance in the follicular unit is essential for cumulus expansion and successful ovulation. While the long pentraxin 3 (PTX3) gene is required for the expansion of cumulus cells (CCs), ovulation, resumption of meiosis and fertilization, the vitamin D receptor gene (VDR-X2) is required for intra-follicle redox balance. This study was planned to determine the expression pattern of VDR-X2 and PTX3 mRNA in CCs isolated from germinal vesicle (GV), metaphase I (MI), and metaphase II (MII) oocytes of PCOS patients with ovulatory dysfunction. METHODS The relative expression of CC-PTX3 and CC-VDR-X2 mRNA were evaluated using qRT-PCR in a total of 79 CC samples collected from individual cumulus-oocyte complex of 40 infertile patients (20 PCOS and 20 non-PCOS normal responders) who underwent ovarian stimulation with the GnRH antagonist protocol. RESULTS Relative PTX3 mRNA expressions of CCMI-control and CCMII-control showed 3- and 9-fold significant upregulation compared to CCGV-control, respectively. The relative PTX3 mRNA expression of CCMII-control increased approximately three fold compared to CCMI-control. Compared to CCGV-pcos, a 3-fold increase was noted in the relative PTX3 mRNA expression of CCMI-pcos and an approximately 4-fold increase in the PTX3 mRNA expression of CCMII-pcos. Relative PTX3 mRNA expression values of CCMII-pcos and CCMI-pcos were similar. A 6-fold upregulation of relative PTX3 mRNA and a 4-fold upregulation of VDR-X2 mRNA were detected in CCMII-control compared to CCMII-pcos. CC-VDR-X2 expression patterns of the PCOS and control groups overlapped with the CC-PTX3 pattern. Fertilization rates of the PCOS group exhibiting failed transcript expression were similar to normal responders. CONCLUSION The fact that relative CC-PTX3 and CC-VDR mRNA expression does not increase during the transition from MI to MII stage in PCOS as in normal responders suggests that PTX3 and VDR expression may be defective in cumulus cells of PCOS patients with ovulatory dysfunction.

Abstract
OBJECTIVE Spinal metastases may only affect the bone tissue and result in spinal instability or may additionally result in epidural compression, leading to neurological deficits. Surgery has emerged as a popular method in treating metastatic epidural spinal cord compression (MESCC) due to the advances in surgical techniques and instrumentation. In this study, we evaluated patients with MESCC regarding neurological status, pain status, and survival rates, and presented our experience managing MESCC. PATIENTS AND METHODS Clinical and radiographic records of 53 patients diagnosed with MESCC between January 2011 and March 2017 were retrospectively evaluated. The study included patients with a pathological diagnosis of primary cancer, those who complained of spinal metastasis, and those who had indications of MESCC on Magnetic Resonance Imaging (MRI). Bone structure and spinal stability were evaluated using assessed Computed Tomography (CT), and metastatic spread was considered using assessed Positron Emission Tomography (PET) in suitable cases. For each patient, the presence of a tumor compressing the spinal cord, age, gender, preoperative, and postoperative American Spinal Injury Association scores (ASIA), Tokuhashi prognostic score (TPS), affected spinal segment, pathological diagnosis, preoperative, and postoperative Visual Analog Scale (VAS), the status of spinal stability, follow-up period, and complications were evaluated. RESULTS Forty-five patients (82.2% of them were women) underwent surgery with a mean age of 58.29 ± 15.14 years. The most frequent type of primary tumor was multiple myeloma (33.9%), followed by lung (24.6%), gastric (7.5%), and prostate (5.7%). The most common site of metastasis was the thoracic region (43.4%), followed by lumbar (24.5%), multiple (24.5%), and cervical (5.7%). The analysis indicated that a significant difference was found between the survival rates of the TPS categories. CONCLUSIONS Common symptoms of MESCC include spinal pain and neurological deficit below the level of the injury. Prompt surgical treatment followed by oncological treatment leads to significant neurological recovery, more prolonged survival, pain relief, and improved quality of life in patients with a short survival time. Oncological treatments, including radiotherapy (RT), should be recommended after surgical treatment.

Abstract
BACKGROUND Non-steroidal anti-inflammatory drug (NSAID) use may cause diaphragm-like lesions in the bowel. Although NSAID-enteropathy is among the causes of protein-losing enteropathy (PLE), intractable hypoalbuminemia is rare. CASE REPORT Here, we discuss a case of NSAID-enteropathy with a diaphragm-like disease that presented with Protein Losing Enteropathy (PLE) rather than obstruction. The hypoalbuminemia recovered immediately after resection of the obstructive segment, despite ongoing annular ulcerations in the early postoperative period. Thus, it was not clear whether obstructive mechanisms influenced resistant hypoalbuminemia besides the ulcers. We also reviewed the English-written literature for "diaphragm-type lesion, NSAID-enteropathy, obstruction, and protein-losing enteropathy". We noted that the role of obstruction in the pathophysiology of PLE was not clear. CONCLUSIONS As our case and a couple of cases reported in literature, slow-onset obstructive pathology seems to contribute to well-known factors: inflammatory response, exudation, tight-junction dysfunction, and increase in permeability in the physiopathology of NSAID-induced PLE. Factors such as distention-induced low-flow ischemia and reperfusion, cholecystectomy-related continuous bile flow, bacterial overgrowth-related bile deconjugation and concomitant inflammation are among other potential influencers. The possible role of a slow-onset obstructive pathology in the physiopathology of NSAID-induced and other PLE needs to be further elucidated.

Abstract
BACKGROUND Homeobox genes A10 (HOXA10) and A11 (HOXA11), members of the abdominal B gene family, are responsible for embryonic survival and implantation. This study was planned to investigate whether endometrial injury alters the expression of both transcripts in women with implantation failure. METHODS A total of 54 women with implantation failure were divided into two equal groups as experimental (scratching) and sham (no scratching). Participants in the scratching group were exposed to endometrial injury in the mid-luteal phase, and those in the sham group were exposed to endometrial flushing. The scratching group, but not the sham group, underwent prior endometrial sampling. A second endometrial sampling was performed on the scratching group in the mid-luteal phase of the following cycle. The mRNA and protein levels of the HOXA10 and 11 transcripts were determined in endometrial samples collected before and after injury/flushing. Participants in each group underwent IVF/ET in the cycle after the second endometrial sampling. RESULTS Endometrial injury caused a 60.1-fold (p < 0.01) increase in HOXA10 mRNA and a 9.0-fold increase in HOXA11 mRNA (p < 0.02). Injury resulted in a significant increase in both HOXA10 (p < 0.001) and HOXA11 protein expression (p < 0.003). There was no significant change in HOXA10 and 11 mRNA expressions after flushing. Clinical pregnancy, live birth, and miscarriage rates of the both groups were similar. CONCLUSIONS Endometrial injury increases homeobox transcript expression at both mRNA and protein levels.

Abstract
Myometrium cells are an important reproductive niche in which cyclic mechanical forces of a pico-newton range are produced continuously at millisecond and second intervals. Overproduction and/or underproduction of micro-forces, due to point or epigenetic mutation, aberrant methylation, and abnormal response to hypoxia, may lead to the transformation of fibroid stem cells into fibroid-initiating stem cells. Fibroids are tumors with a high modulus of stiffness disturbing the critical homeostasis of the myometrium and they may cause unfavorable and strong mechanical forces. Micro-mechanical forces and soluble-chemical signals play a critical role in transcriptional and translational processes' maintenance, by regulating communication between the cell nucleus and its organelles. Signals coming from the external environment can stimulate cells in the format of both soluble biochemical signals and mechanical ones. The shape of the cell and the plasma membrane have a significant character in sensing electro-chemical signals, through specialized receptors and generating responses, accordingly. In order for mechanical signals to be perceived by the cell, they must be converted into biological stimuli, through a process called mechanotransduction. Transmission of fibroid-derived mechanical signals to the endometrium and their effects on receptivity modulators are mediated through a pathway known as solid-state signaling. It is not sufficiently clear which type of receptors and mechanical signals impair endometrial receptivity. However, it is known that biomechanical signals reaching the endometrium affect epithelial sodium channels, lysophosphatidic acid receptors or Rho GTPases, leading to conformational changes in endometrial proteins. Translational changes in receptivity modulators may disrupt the selectivity and receptivity functions of the endometrium, resulting in failed implantation or early pregnancy loss. By hypermethylation of the receptivity genes, micro-forces can also negatively affect decidualization and implantation. The purpose of this narrative review is to summarize the state of the art of the biomechanical forces which can determine fibroid stem cell transformation and, thus, affect the receptivity status of the endometrium with regard to fertilization and pregnancy.

Abstract
Conventional open thyroidectomy is still considered the gold standard for thyroid surgery. Transoral endoscopic thyroidectomy vestibular approach (also known as TOETVA) is often considered to be more advantageous than the other approaches, such as minimally invasive video assisted thyroidectomy, thyroidectomy via breast/axillary/retroauricular access, bilateral axillo-breast approach and axillo-bilateral breast approach. In this scoping review, we discuss the risks and the benefits of this surgical approach and its medico-legal and ethical implications, particularly focusing on the importance of practice on cadavers. Currently, there is little scientific evidence supporting TOETVA, since there are few papers on the comparison with the traditional open thyroidectomy that have been published and thus little data on the long-term outcomes of TOETVA are available. Since the better cosmetic outcome currently represents the main indication for this surgical technique, substantial medico-legal and ethical issues arise. Moreover, practice on cadavers can help surgeons to develop the technical and non-technical skills required to perform efficiently and safely this new surgical procedure.

Abstract
In this study conformation analysis of seven drugs commonly used in the treatment of COVID-19 was performed. The most stable conformers of the drug molecules were used as initial data for docking analysis. Using the Cavityplus program, the probable most active binding sites of both apo and holo forms of COVID-19 main protease enzyme (Mpro) and spike glycoprotein of SARSCoV-2 receptors were determined. The interaction mechanisms of the 7 FDA approved drugs (arbidol, colchicine, dexamethasone, favipiravir, galidesivir, hydroxychloroquine, remdesivir) were examined using the AutoDock Vina program. The six of the seven drugs were found to be more stable in binding to apo form of COVID-19 Mpro and spike glycoprotein. Moreover, a set of molecular mechanics (MM) Poisson-Boltzmann (PB) surface area (SA) calculations on the investigated drugs-protein systems were performed and the estimated binding free energy of remdesivir and the apo form of Mpro system was found to be the best. The interaction results of FDA drugs with the apo form of COVID-19 Mpro and spike glycoprotein can play an important role for the treatment of COVID-19.

Abstract
The specialized resident-stem cells in gonads are tasked with restorating damaged ovarian cells following injury to maintain sequential reproductive events. When we talk about premature ovarian insufficiency (POI) we accept the existence of decreased stem cell and their regenerative abilities. The present study was to explain how restorating damaged ovarian cells following injury to maintain sequential reproductive events in evidence-based medicine indexed in PubMed and Web of Science. The exact mechanism is unclear stem cells transfer may improve compromised ovarian function and fertility outcome in women with POI. Soluble factors secreted by stem cell may rescue impaired mitochondrial function in oogonial stem cells, enhance metabolic capacity of resident stem cells, induce local neovascularization in the ovary, and activate gene shifting between transferred stem cells and germ cell precursors. This review may provide insight into how stem cells show some of their beneficial effects on compromised ovarian microenvironment and germ cell niche and paves the way for clinical trials for improving ovarian function of women with POI. We also had the opportunity to share our hypothesis about the design and development of induced oogonial stem cell (iOSC) and its use in POI.

Abstract
PURPOSE To evaluate the effect of alpha-blocker treatment prior to transrectal ultrasound-guided prostate biopsy (TRUS-Bx) on voiding functions, pain scores and health-related quality-of-life outcomes. MATERIALS AND METHODS From January 2018 to April 2019, a total of 112 patients underwent TRUS-Bx due to elevated prostate-specific antigen (PSA) or abnormal digital rectal examination findings. Patients were divided into 2 groups depending on whether they received pharmacological treatment before biopsy. Group 1 consisted of patients with no alpha-blocker treatment prior to biopsy and Group 2 consisted of patients who received Tamsulosin for one week before biopsy continuing for one week after biopsy. Voiding function was evaluated three times using the validated International Prostate Symptom Score (IPSS) and uroflowmetry (maximal flow rate (Qmax) and residual volume (PVR)). The Turkish version of the Medical Outcomes Study Short Form 36-item Questionnaire (SF-36) was used to assess health-related quality of life. Pain scores were rated according to the Visual Analogue Scale (VAS) just after the biopsy procedure. RESULTS Mean IPSS and Qmax on the post-biopsy 7 day were significantly in favor of Group 2 (P<0.001, P=0.004). Although post-biopsy day 7 PVR was similar between the groups, Δ1 PVR was significantly in favor of Group 2 (P=0.004). Mean VAS score was 2.7±2.3 for the Tamsulosin group and 4.2±2.2 for the control group (P=0.001). There was no significant difference between two groups according to baseline and postoperative 1st month SF-36 scores. CONCLUSION Alpha-blocker therapy prior to TRUS-Bx is effective in preventing voiding dysfunction and biopsy-related pain in patients undergoing TRUS-Bx. LEVEL OF EVIDENCE 2.

Abstract
The follicle must fulfill the following criteria if it is to survive the period between early embryonic life and the luteinizing hormone (LH) peak. It should (i) be surrounded by pregranulosa cells; (ii) complete the first meiotic division and become dormant; and (iii) continue metabolism during the dormant stage. Interaction between the natriuretic peptide precursor type C (Nppc) and its receptor, natriuretic peptide receptor 2 (Npr2), affects female fertility through the production of oocytes with developmental capacity and maintain oocyte meiotic arrest. While Nppc is expressed in mural cells, cumulus cells express Npr2. Nppc/Npr2 system exerts its biological function on developing follicles by increasing the production of intracellular cyclic guanosine monophosphate (cGMP). This pathway not only contributes to the development of ovary and the uterus, but aids the formation of healthy eggs in terms of their morphological and genetic aspects. A defect in this pathway leads to asmall ovarian size, string-like uterine horns, and thin endometrium and myometrium. Disorganized chromosomes, abnormal cumulus expansion and early meiotic resumption occur in animals with defective Nppc/Npr2 signaling. The types and number of oocytes also decrease when there is incompetent Nppc/Npr2 signaling. This paper extends on most recent and relevant experimental evidence regarding Nppc/Npr2/cGMP signaling with regard to its crucial role in maintaining oocyte meiotic arrest and the production of oocytes with developmental capacity. We further discuss whether the agonist or antagonist forms of the members of this exciting pathway can be usedfor triggering final oocyte maturation.

Abstract
OBJECTIVE Human sirtuin-3, a protein involved in the mediation of tumors, has been shown to be present in malignancies. The goal of this study was to measure serum sirtuin-3 levels in esophageal squamous cancer cells and to determine whether sirtuin-3 may possess predictive value in advanced cases of esophageal squamous cell carcinoma (ESCC). PATIENTS AND METHODS A total of 130 ESCC patients and 50 healthy control subjects participated to the study. Serum sirtuin-3 levels for all 180 subjects were measured using enzyme-linked immunosorbent assay (ELISA). RESULTS Median sirtuin-3 levels were significantly higher in patients with ESCC than in the control subjects. CONCLUSIONS The presence of considerably elevated levels of sirtuin-3, could be a powerful mediator of advanced ESCC in ESCC patients, suggests that sirtuin-3 may be a useful indicator of the disease.

Abstract
Embryos have evolved a remarkable capacity to find implantation site. The impressive navigation ability of natural blastocysts may rely on highly sensitive signals arising from embryos and specialized signal processing strategies in the endometrium. Navigation capabilities may be compromised in ICSI embryos because of altered biochemical signaling. The design and delivery of artificial blastocyst (AB) carrying strong chemical signals may allow ICSI embryos to more easily locate to and be retained in the implantation zone. ICSI embryos will attach easily to the implantation zone after it is found by the AB. Co-transfer of the AB together with the ICSI embryo may overcome potential difficulties in implantation due to impaired embryo-maternal communication in cases with implantation failure.

Abstract
OBJECTIVE Prehospital and hospital care during incidents of mass violence and civil conflict involve a number of aspects that distinguish it from care during times of peace. We aimed to analyze the dynamics and outcomes of prehospital and hospital care during ongoing conflicts. STUDY DESIGN Multicentric prospective observational study. METHOD Patients enrolled in the study, which was conducted in Turkey, were all injured in armed conflict and taken to level 1 trauma centers. On admittance, patients were requested to complete a semistructured questionnaire containing questions on patient demographics, transport type, weapons used, injury severity score (ISS), and other incident-related factors. We analyzed patient outcomes (mortality, morbidity, complications, and length of hospital stay) and transfers of patients between hospitals. The present study evaluated the cases of 390 victims enrolled over a 9-month period and followed up for 6 months. RESULTS The majority of patients were transported by ambulances (n = 334, 85.6%); other transport modes were helicopters (n = 32, 8.2%) and private vehicles (n = 24, 6.2%). Nearly half of patients (48.7%) did not benefit by changing hospitals. During transport to hospitals, 4.1% of the vehicles in the study were involved in accidents. Using multiple regression analysis, only ISS (odds ratio [OR]: 1.098, 95% confidence interval [CI]: 1.044-1.156) and the Glasgow Coma Scale (OR: 0.744, 95% CI: 0.639-0.866) were found to affect mortality. In Receiver-operator characteristic analysis, a cutoff value of 22.5 for ISS had a sensitivity of 100% and a specificity of 89.6% for mortality. CONCLUSIONS Despite lower ISS values, patient outcomes were worse in terror incidents/civil conflicts. Transport modes did not significantly affect outcomes, whereas hospital transport was found to be inefficiently used.

Abstract
As with other organs endometrial functions are altered with the advancing age. Age related decrease in reproductive functions leads to decline in the number of oocytes retrieved and the synthesis of endometrial receptivity molecules. Despite the significant improvement in assisted reproductive technologies we do not have so many options to enhance endometrial receptivity. Due to lack of drugs having endometrium receptivity enhancement properties, oocyte donation seems to be the only solution for women with implantation failure. The euploid oocytes come from young and healthy donors may overcome age associated endometrial receptivity defect. Nevertheless, many reasons restrict us from using oocyte donation in women with implantation failure. We, therefore, hypothesized that by mimicking a young blastocyst's effect on endometrium, the transfer of genuine embryos and implantation-promoting compounds together might be the new treatment option for infertile women with recurrent implantation failure. Artificial beads, MI or GV oocytes, and empty zona can be used as a container for intrauterine replacement of implantation-promoting compounds.

Abstract
OBJECTIVE Ischemia-modified albumin (IMA), a novel biochemical marker, is known to reflect ischemia in early phases of acute coronary syndrome (ACS). In the present study, we evaluated the role of IMA on the prediction of coronary atherosclerotic plaque burden and ischemic burden in patients with non-ST-segment-elevation acute coronary syndromes (NSTEACS). PATIENTS AND METHODS Ninety-six consecutive NSTEACS patients presented within the first three hours of symptom onset were prospectively enrolled in this study. Blood samples were collected in the first 30 min of admission for IMA measurement. Serum levels of IMA were analyzed using the rapid and colorimetric method and reported in absorbance units (ABSU). Coronary plaque burden was assessed by using angiographic Gensini score (GS). In addition, patients were divided into large (LIBG) and small ischemic burden (SIBG) groups based on angiography findings. RESULTS Patients were dichotomized into two groups according to median GS as follows; with GS ≤ 44 and GS > 44, respectively. Mean IMA was significantly higher in GS > 44 group as compared to GS ≤ 44 group (0.746 ± 0.15 vs. 0.550 ± 0.12 ABSU, p < 0.001). The GS was positively correlated with the levels of IMA (r = 0.673, p < 0.001). IMA was significantly higher in LIBG as compared to SIBG (0.745 ± 0.16 vs. 0.570 ± 0.13 ABSU, p < 0.001). CONCLUSIONS IMA measurement in early phases of NSTEACS may give predictive information about ischemic burden and coronary atherosclerotic plaque burden; thus, may be useful in decision-making about treatment options in these patients.

Abstract
Emigration is defined as a synchronized movement of germ cells between the yolk sack and genital ridges. The miraculous migration of germ cells resembles the remigration of salmon traveling from one habitat to other. This migration of germ cells is indispensible for the development of new generations. It is not, however, clear why germ cells differentiate during migration but not at the place of origin. In order to escape harmful somatic signals which might disturb the proper establishment of germ cells forced germ cell migration may be necessary. Another reason may be to benefit from the opportunities of new habitats. Therefore, emigration may have powerful effects on the population dynamics of the immigrant germ cells. While some of these cells do reach their target, some others die or reach to wrong targets. Only germ cell precursors with genetically, and structurally powerful can reach their target. Likewise, epigenetic reprogramming in both migratory and post-migratory germ cells is essential for the establishment of totipotency. During this journey some germ cells may sacrifice themselves for the goodness of the others. The number and quality of germ cells reaching the genital ridge may vary depending on the problems encountered during migration. If the aim in germ cell specification is to provide an optimal ovarian reserve for the continuity of the generation, then this cascade of events cannot be only accomplished at the same level for every one but also are manifested by several outcomes. This is significant evidence supporting the possibility of unique individual ovarian reserve.

Abstract
Acylated ghrelin (AG) effect on GnRH secretion is mediated, at least in part, by GH secreta-gogue receptor (GHS-R) which is present in the GnRH neurons. As the acylation is mandatory for binding to GHS-R, unacylated isoform of ghrelin (UAG) action on gonadotropin secretion is likely to be mediated by other receptors or mediators that have not been identified yet. UAG, therefore, may act partially via a GHS-R-independent mechanism and inhibitory impact of UAG on GnRH neurons may be executed via modulation of other neuronal networks. Ghrelin and gonadotropin inhibitory hormone (GnIH), two agonistic peptides, have been known as important regulators of reproductive events. Potential impact of ghrelin on the activity of GnIH neurons is not exactly known. Both GnIH and ghrelin are potent stimulators of food intake and inhibitors of gonadotropin release. By binding G-protein coupled GnIH receptor (GnIH-R), GPR147, which is located in the human gonadotropes and GnRh neurons, GnIH exerts an inhibitory effect on both GnRH neurons and the gonadotropes. The GnIH-GPR147 system receives information regarding the status of energy reservoir of body from circulating peptides and then transfers them to the kisspeptin-GnIH-GnRH network. Due to wide distribution of this network in brain GnIH neurons may project on ghrelin neurons in the arcuate nucleus and contribute to the regulation of UAG's central effects or vice versa. Together, the unidentified ghrelin receptor in the hypothalamus and hypophysis may be GnIH-R. Therefore, it is reasonable that ghrelin may act on both hypothalamus and hypophysis via GnIH-GPR147 system to block gonadotropin synthesis and secretion.

Abstract
INTRODUCTION The risk of kidney stone formation increases with urinary stasis, which is associated with decreased peristaltism. The relationship between nonobstructive kidney stone formation and ureteral jet dynamics, which can be measured with Doppler ultrasonography (US) and provide information about ureteral peristaltism, has been demonstrated in adults. OBJECTIVE To investigate the relationship between ureteral jet dynamics, which provide information about ureteral peristaltism, and stone formation in children. STUDY DESIGN Children admitted to Dokuz Eylul University Hospital with flank pain, and asymptomatic age-matched children for the control group, were prospectively enrolled and underwent Doppler US for diagnostic reasons and bilateral ureteral jet flow measurements. Children diagnosed with unilateral nonobstructive lower pole kidney stones formed Group 1, and the control group, without any evidence of stone disease, formed Group 2. Ureteral jet dynamics were compared between the affected renal units in Group 1, and healthy renal units in Group 1 and Group 2. RESULTS A total of 32 children were included for each group. The mean average jet flow-rate (JETave (cm/second)) in affected renal units in Group 1 was found to be significantly lower than in the healthy renal units in Group 1 and left and right healthy renal units in Group 2 (P < 0.05). The continuous JETpattern rate in affected renal units in Group 1 was found to be significantly higher compared with healthy renal units in Groups 1 and 2 (P = 0.012) (Table). The odds ratio for kidney stone formation was 5.6 for renal units with JETave <9.5 cm/s when compared with renal units with JETave ≥9.5 cm/s. DISCUSSION In a recent study, it was demonstrated in adults that low ureteral jet flow-rate and continuous JETpattern were significantly higher in affected renal units. The findings in children were also similar to adults: the mean JETave was significantly lower and determination rate of continuous flow pattern was significantly higher in affected renal units. CONCLUSIONS Children with low JETave and continuous JETpattern as a sign of decreased ureteral peristaltism are at an increased risk of kidney stone formation. However, it is vital that further studies are conducted to elaborate on this topic.

Abstract
AIM We aimed to assess the utility of DN4 questionnaire (Douleur Neuropathique en 4 questions) to define the frequency and severity of neuropathic pain (NP) and also its clinical correlation to daily clinical practice. METHODS We included 1357 patients with diabetes (56.5% women, 90.4% type 2 diabetes) who were followed up in our diabetes outpatient clinic. Presence of NP was evaluated by performing simultaneous DN4 questionnaires and physical examination. Those who had a DN4 score ≥4 were considered to have NP. RESULTS The mean age was 58.2±12.1 years, mean duration was 12.5±7.5; (min-max: 1-45) years, mean HbA1c level was 7.8±1.6% (min-max: 5-16.2%), (61.7±6.0mmol/mol; min-max: 31.1-153.6mmol/mol). Three hundred thirteen patients (23%) were diagnosed with NP using the DN4 tool. Male gender (p=0.01), receiving antihypertensive treatment (p=0.01), presence of retinopathy (p<0.001), cardiovascular disease (CVD) (p=0.01) and previously diagnosed neuropathy (p<0.001) were significantly associated with higher NP scores. Those who had increased DN4 scores were more likely to be on oral hypoglycemic agents (OHA)+insulin combinations (p<0.001), had longer diabetes duration (p<0.001) and higher HbA1c levels (p=0.001). Logistic regression model revealed that diabetes duration (OR: 1.02, 95% CI: 1.00-1.04, p=0.007), elevated HbA1c levels (1.11, 1.02-1.21, 0.015), presence of retinopathy (1.41, 1.20-1.64, <0.001), management with at least one OHA (1.47; 1.12-1.92; 0.004) or any insulin regimen (1.62; 1.16-2.27; 0.005) (compared with diet only-regimens) were significantly associated with NP. CONCLUSION Utilization of DN4 questionnaire in daily clinical practice is an effective tool in the identification of pain related with peripheral diabetic polyneuropathy.

Abstract
In this study, the effects of Mannich bases containing bis-1,2,4-triazole on the levels of in vivo malondialdehyde (MDA) and antioxidant vitamins (A, E, C) were examined in serum, livers and kidneys of rats. DA and vitamin (A, E, C) levels were determined by high performance liquid chromatography (HPLC). Antioxidant effect was investigated by determining the MDA levels in Saccharomyces cerevisiae cells as in vitro. Furthermore, the antitumor effects of compounds were investigated against MCF-7 human breast cancer cells. Interrelations of results among control and compound groups were evaluated using SPSS statistical software package. As a result, some of the compounds showed effective biological activity when compared to control conditions. The test compounds used in this study may be effective for utilization in the selection and design of model compounds for further studies.

Abstract
Background: Intraoperative testing of gastrointestinal anastomosis effectively ensures anastomotic integrity. This study investigated whether the routine use of methylene blue intraoperatively identified leaks to reduce the postoperative proportion of clinical leaks. Methods: This study retrospectively analyzed consecutive total gastrectomies performed from January 2007 to December 2014 in a university hospital setting by a general surgical group that exclusively used the methylene blue test. All surgeries were performed for gastric or junctional cancers (n = 198). All reconstructions (Roux-en Y esophagojejunostomy) were performed using a stapler. The methylene blue test was used in 108 cases (group 1) via a nasojejunal tube. No test was performed for the other 90 cases (group 2). Intraoperative leakage rate, postoperative clinical leakage rate, length of hospitalization, and mortality rate were the outcome measures. Results: The intraoperative leakage rate was 7.4% in group 1. The postoperative clinical leakage rate was 8.6%. The postoperative clinical leakage rate was 3.7% in group 1 and 14.4% in group 2 (p = 0.007). There were no postoperative clinical leaks when an intraoperative leak led to concomitant intraoperative repair. The median length of hospital stay was 6 days in group 1 and 8 days in group 2 (p < 0.001). One death occurred in each group. No test-related complications were observed. Conclusion: The methylene blue test for esophagojejunostomy is a safe and reliable method for the assessment of anastomosis integrity, especially in cases with difficult esophagojejunostomic construction.

Abstract
A 35-year-old male patient was admitted with fatigue and muscle weakness. He had been on methimazole due to thyrotoxicosis for 2 weeks. Laboratory tests showed overt hyperthyroidism and hypokalemia. Potassium replacement was started with an initial diagnosis of thyrotoxic hypokalemic periodic paralysis. Later on, despite the euthyroid condition and potassium chloride treatment, hypokalemia persisted. Further investigations revealed hyperreninemic hyperaldosteronism. The patient was considered to have Gitelman's syndrome (GS) and all genetic analysis was done. A c. 1145C>T, p. Thr382Met homozygote missense mutation located on solute carrier family 12, member gene 3, exon 9 was detected and GS was confirmed.

Abstract
BACKGROUND/OBJECTIVES To evaluate the harmful effects of 5-floururacil (5-FU) and Irinotecan on the liver and to determine the role of Pioglitazone in averting liver damage. METHODS Sixty Sprague-Dawley female rats were divided into 4 groups. The first group (n=20) was administered 40 mg of 5-FU and 40 mg kg of Irinotecan intraperitoneally for 4 cycles, while the second group (n=20) received 4 mg kg of Pioglitazone by gastric gavage at 5 days a week for 20 days in addition to chemotherapy. The third group (n=10) was the sham group; chemotherapy regimen was given as in the first group. In addition, normal saline was given daily for 20 days by gastric gavage. The fourth group (n=10) was only given a standard diet as a control group. Then, blood samples were studied for the evaluation of alanine aminotransferase (AST)and alanine aminotransferase (ALT) levels. And left liver lobes of rats were taken for pathological analysis. RESULTS Although short-term chemotherapy was administered,aminotransferase (AST) and alanine aminotransferase (ALT)levels were found to be significantly higher in the first and third groups compared to the others (p 0.0001). No significant difference was determined between the second and the control group. Pioglitazone reduced the adverse metabolic effects of chemotherapy on the liver, but had no effect on the histopathological changes. CONCLUSION short-term CT causes metabolic disruption in hepatocytes, but not relevant with CASH. Preventive treatments like Pioglitazone should be used more carefully.

Abstract
We sought to determine the ability of quantitative myocardial perfusion reserve index (MPRI) by cardiac magnetic resonance (CMR) and high-sensitive troponin T (hsTnT) for the prediction of cardiac allograft vasculopathy (CAV) and cardiac outcomes in heart transplant (HT) recipients. In 108 consecutive HT recipients (organ age 4.1±4.7 years, 25 [23%] with diabetes mellitus) who underwent cardiac catheterization, CAV grade by International Society for Heart & Lung Transplantation (ISHLT) criteria, MPRI, late gadolinium enhancement (LGE) and hsTnT values were obtained. Outcome data including cardiac death and urgent revascularization ("hard cardiac events") and revascularization procedures were prospectively collected. During a follow-up duration of 4.2±1.4 years, seven patients experienced hard cardiac events and 11 patients underwent elective revascularization procedures. By multivariable analysis, hsTnT and MPRI both independently predicted cardiac events, surpassing the value of LGE and CAV by ISHLT criteria. Furthermore, hsTnT and MPRI provided complementary value. Thus, patients with high hsTnT and low MPRI showed the highest rates of cardiac events (annual event rate=14.5%), while those with low hsTnT and high MPRI exhibited excellent outcomes (annual event rate=0%). In conclusion, comprehensive "bio-imaging" using hsTnT, as a marker of myocardial microinjury, and CMR, as a marker of microvascular integrity and myocardial damage by LGE, may aid personalized risk-stratification in HT recipients.

Abstract
BACKGROUND Association of androgenetic alopecia (AGA) with increased incidence of hypertension, a strong risk factor for coronary artery disease, has been suggested. However, there are no data on arterial stiffness measures of asymptomatic young adults with AGA. OBJECTIVE In this study, we aimed to investigate the association of the AGA with arterial stiffness assessed by cardio-ankle vascular index (CAVI), in asymptomatic young men. METHODS A total of 162 asymptomatic men aged between 18 and 45 years were consecutively enrolled to the study. Subjects were considered to have AGA if they have ≥3 grade vertex alopecia according to Hamilton-Norwood scale. Arterial stiffness was assessed by CAVI and defined as abnormal if CAVI is ≥8. RESULTS Frequency of abnormal CAVI was higher in patients with AGA (29.3% vs. 10.0%, P = 0.003). Subjects with AGA had higher mean CAVI than subjects without AGA (7.56 ± 0.93 vs. 7.15 ± 0.79, P = 0.004). Binary logistic regression analysis demonstrated that presence of AGA (OR, 5.6; 95% CI, 1.7-20.0, P = 0.006), age (OR, 1.1; 95% CI, 1.0-1.2, P = 0.03) and diastolic blood pressure (OR, 1.1; 95% CI, 1.0-1.3, P = 0.005) were independently associated with abnormal CAVI. CONCLUSION We concluded that, AGA might be an indicator of arterial stiffness in asymptomatic young adults.
