Abstract
Background and Purpose Postoperative pain is a significant problem in thoracotomy patients. Our aim in this study was to investigate the relationship between postoperative pain and neutrophil-to-lymphocyte ratio (NLR) which is a marker of acute inflammatory response. Materials and Methods Thoracic epidural or intravenous analgesia was administered to thoracotomy patients who elected to undergo a planned surgery. Patients were divided into two groups according to the analgesia method applied postoperatively. Thoracic epidural analgesia was recorded as Group 1 and intravenous analgesia as Group 2. Whole blood counts were recorded from preoperative and postoperative 24th- and 48th-hour routine blood samples, and NLRs were recorded as retrospective file scanning. Postoperative 24th- and 48th-hour NLRs and preoperative NLR values were recorded. Results Demographic data of the patients included in the study were similar except for age. Preoperative NLR was significantly higher in Group 1 at 3.50 (P = 0.004) than in Group 2 at 2.51. Postoperative NLRs were similar among both groups. Postoperative NLR values at both the 24th- and 48th-hour increased by4.9 times in Group 1 and 9.23 times in Group 2 from the 24th-hour preoperative period, when the preoperative NLRs were evaluated. The rate of increase in Group 1 was significantly lower than in Group 2 (P = 0.006). Conclusion Postoperative NLR alterations when compared with preoperative values were related to the analgesic regimen used.

Abstract
AIM We aimed to study the effects of thymoquinone on erythrocyte deformability in an experimental model of sepsis given before or after the initiation of the sepsis model. METHOD The animals were grouped as (n = 6) control, nigella sativa, sepsis, sepsis group with administration of nigella sativa before sepsis development and sepsis group with nigella sativa administration after sepsis development. Cecal ligation and puncture model (CLP) was used to induce sepsis in the animals. The thymoquinone was given 1 hour before or after the CLP in the study groups with a dose of 500 mg·kg(-1). Erythrocyte deformability and relative resistance was calculated. RESULT Relative resistance was increased in the sepsis groups when compared to the control group (p < 0.0001). Deformability index was increased in the sepsis group when compared to the other groups (p < 0.0001 in all groups). Sepsis group with after nigella sativa groups deformability index was significantly different from the deformability index in control group (p = 0.002). The use of nigella sativa before the initiation of sepsis corrected the deformability index significantly and the results were comparable to the control group (p = 0.078). CONCLUSION Thymoquinone administration before induction of CLP was observed to have protective effects on these alterations in CLP sepsis (Tab. 1, Fig. 1, Ref. 26).

Abstract
Background and Aim Technological developments and enhancement of knowledge level enable heart surgery with low mortality rates in most centers. On the other hand, increased systemic inflammatory response against cardiopulmonary bypass (CPB) plays a critical role in the development of postoperative complications. We aimed to compare the effects of centrifugal pump where it is claimed that blood is exposed to minimal trauma and roller pump techniques on inflammatory response and oxidant status during CPB. Materials and Methods : A total of 40 patients, who had coronary artery disease and underwent coronary artery bypass graft (CABG) surgery using either roller or centrifugal pump between June 2012 and June 2013 were enrolled in this study. Patients over 40 years old and without any known immunologic, infectious, or inflammatory incidents and hematological problems for the past 6 months were included in the study. Two study groups (Group R: roller pump group and Group C: centrifugal pump group) were created. During CABG surgery tumor necrosis factor (TNF) alpha, interleukin (IL)-6, IL-8, superoxide dismutase (SOD), catalase (CAT), and nitric oxide levels were measured before and after CPB. Results TNF alpha, IL-6, and IL-8 levels measured before and after CPB were found to be similar between groups. SOD, CAT and Nitric oxide levels were also similar between groups. After the CPB period, glutathione peroxidase enzyme activities in Group R measured after CPB were significantly lower than those measured in Group C. The platelet-activating factor (PAF) levels before CPB usage period were same in both groups, where PAF levels after CPB were found to be significantly higher in roller pump group than centrifugal pump group. At inter-group comparisons, the levels of PAF were same at each group before and after CPB. Conclusion The study findings indicate that usage of the centrifugal pump does not have a clear superiority in terms of the effects on inflammatory response and oxidant status during CPB when compared to roller pump. Nevertheless, we believe that our results should be supported by further clinical and experimental studies.

Abstract
OBJECTIVES Erythrocyte deformability and plasma viscosity are of crucial importance for the perfusion of tissues and organs. The aim of this study was to evaluate the effect of apelin-13 on erythrocyte deformability during IR heart injury in diabetic rats. METHODS Eighteen Wistar Albino rats were included in the study after streptozotocin (55 mg/kg) treatment for four weeks of observation for diabetes existence. The animals were randomly assigned to one of five experimental groups. In the Group C, DC (sham-control group) and DCA (sham-control group-apelin-13), the coronary artery was not occluded or re-perfused. In the Group DIR, a branch of the left coronary artery was occluded for 30 minutes followed by 90 minutes of re-perfusion to produce IR. In the Group DIRA, a branch of the left coronary artery was occluded for 30 minutes followed by 90 minutes of re-perfusion to produce IR, and apelin-13 was administrated via 10 µg.kg-1 IP route 30 minutes before ligating the left coronary artery.Deformability measurements were performed in erythrocyte suspensions containing Htc 5% in a PBS buffer. RESULTS The deformability index was significantly increased in diabetic rats; however, it was similar in Group DC, DCA and DIRA. It was significantly increased in the Group DIR when compared to the Group C, DIRA, DCA and DC. The relative resistance was increased in IR models. CONCLUSION Erythrocyte deformability was decreased in rats having diabetes and IR injury. This injury might lead to further problems in microcirculation. It was shown that apeline-13 may be useful in enhancing the adverse effects of this type of injury (Fig. 1, Ref. 35).

Abstract
AIM/INTRODUCTION Analgesic, anti-inflammatory and anti-apoptotic effects of pregabalin have been shown previously. In this study, we investigated the protective effect of different doses of pregabalin on skeletal muscle IR injury in rats. MATERIALS AND METHODS 24 rats were randomly divided into 4 groups (Control, Ischaemia-Reperfusion (IR), IR-Pregabalin 50 mg, IR-Pregabalin 200 mg). Following IR, serum Ischemia Modified Albumin (IMA) and tissue Paraoxonase (PON) were studied and gastrocnemius muscle tissue was removed for histopathologic examination. RESULTS Interstitial inflammation was higher in the IR group than in the control and Pregabalin 200 mg groups (p = 0.037, p = 0.037, respectively). Congestion was higher in the IR group than in the control, Pregabalin 50 and 200 mg groups (p = 0.001, p = 0.004, p = 0.004, respectively). PON was lower in the IR group than in the Control, Pregabalin 50 and 200 mg groups (p = 0.001, p = 0.007, p = 0.015, respectively). IMA was higher in the IR group than in the Control, Pregabalin 50 and 200 mg groups (p < 0.0001, all). CONCLUSION We think that administration of pregabalin, more prominent at 200 mg, can reverse the injury that occurs in the skeletal muscle of IR-induced rats. Pregabalin can be safely used for analgesia in cases of IR (Tab. 2, Fig. 9, Ref. 41).

Abstract
INTRODUCTION Alternative and complementary therapy systems, such as homeopathy, have long been used around the world. Since 1995 homeopathy has been officially recognized in Europe as a system of medicine or a medical specialty. Portuguese community pharmacists have long-standing experience with homeopathic products. By contrast, healthcare professionals in Turkey are less experienced with homeopathic practice although there is a new regulatory setting in place. There are a limited number of studies addressing pharmacists' role within the homeopathic system. AIM To investigate the attitudes (knowledge, feelings and behaviour) of experienced Portuguese pharmacy practitioners who deal with homeopathy, and thus to inform Turkish pharmacy practice and policy on homeopathy-related success factors. METHODS A qualitative cross-sectional design was followed, using semi-structured and face-to-face individual interviews with purposively selected Portuguese pharmacists experienced with homeopathic medicines. Audio-recordings were transcribed verbatim and the transcriptions imported into QSR NVivo v10 software for qualitative coding and analysis. Using a thematic content approach, the extracted codes were grouped and indexed by recurrent themes through a reflective procedure and constant comparison. RESULTS & DISCUSSION Six general themes emerged, the most relevant being participants' feelings of gratitude for the ability to work in homeopathy; other themes were a helpful regulatory body, clear practice boundaries, scientific support and product quality assurance. Specialized homeopathic education was considered the most important factor for success. This was related to patients' positive perceptions and acceptance, suggesting an increase in public awareness through the pharmacy network. CONCLUSIONS Portuguese pharmacists' attitudes towards their homeopathic practices highlighted the key elements for success in a field that is usually distant from traditional pharmaceutical education and practice. The present findings provide guidance for Turkish pharmacists willing to expand their professional scope and to embrace complementary medicines.

Abstract
BACKGROUND AND AIM Acute hind limb ischemia reperfusion (I/R) injury is a common consequence of abdominal aorta cross‑clamping during aortic surgery. Erythrocyte deformability is affected by I/R process and may lead to increased tissue and organ injury. Lornoxicam and intravenous ibuprofen are becoming commonly used as non-steroidal anti-inflammatory drugs (NSAID) for postoperative analgesia. In this study, we aimed to investigate the effects of lornoxicam (2 mg/kg iv) and intravenous ibuprofen (30 mg/kg iv) on erythrocyte deformability in I/R model in rats. MATERIALS AND METHODS Four study groups, each containing 6 Wistar rats were created. Laparotomy was performed in all groups under general anesthesia with ketamine and xylazine. In all groups except sham group, ischemia and reperfusion were achieved by clamping and declamping the infrarenal abdominal aorta for 120 minutes. Rats in Group IR+L received intravenous infusion of lornoxicam (2 mg/kg) while rats in Group IR+I received intravenous infusion of ibubrofen (30 mg/kg) following 2 hours of ischemic period. At the end of reperfusion period, erythrocyte packs were prepared from heparinized blood samples. Erythrocyte suspensions with hematocrit at a concentration of 5% in a phosphate‑buffered saline (PBS) were used in order to perform deformability measurements. The value of p<0.05 was considered statistically significant. RESULTS Relative resistance has increased in ischemia reperfusion group when compared to control group (p < 0.0001). Lornoxicam or ibuprofen intravenous treatments did not change the erythrocyte deformability during ischemia reperfusion period in rats (p=0.851, p=0.690). CONCLUSION Intravenous ibuprofen or lornoxicam administrations during ischemia reperfusion period in rats have no negative effect on erythrocyte deformability. The findings of the study should be supported with more detailed and extensive clinical/experimental studies in the future (Fig. 1, Ref. 18).

Abstract
Introduction Our aim was to investigate the relationship between serum omentin-1 levels and endothelial dysfunction in obese patients. Material and Methods We evaluated 50 obese patients, and age/gender matched 45 healthy non-obese subjects as controls. Oral glucose tolerance test, lipid parameters, uric acid levels, homeostatic model assessment-insulin resistance (HOMA-IR) index, serum omentin-1 levels and flow mediated dilatation (FMD) % were measured in all subjects. Body compositions were analyzed with bioelectrical impedance method using a Tanita Body Composition Analyzer and ViScan. Results Serum omentin-1 levels were found significantly lower in obese population compared to the control subjects. FMD response was significantly decreased in obese population. There was a significant positive correlation between serum omentin-1 levels and FMD response (r=0.359, p<0.001). Serum omentin-1 levels were negatively correlated with body mass index (BMI), waist circumference, total fat percentage, visceral fat, fasting insulin and HOMA-IR index. Conclusion Lower serum omentin-1 levels and decreased FMD response may be an early marker of endothelial dysfunction in obese patients.

Abstract
AIM Intraoperative blood glucose concentration is known to be an independent risk factor for morbidity and mortality in patients undergoing cardiovascular surgery. Arterial blood gas analysis is an important investigation to monitor the acid-base balance and gas exchange in these patients. Hyperglycemia leads to a series of metabolic changes which affect acid-base balance and serum electrolytes. In this study, we aimed to look into the effect of glycemic control on arterial blood gas parameters, serum electrolytes, and hemoglobin (Hb). MATERIALS AND METHODS We collected data from diabetic patients who underwent cardiovascular surgery between 2010 and 2014. The patients were divided into two groups according to the insulin infusion protocols applied such as with conventional (180-250 mg/dl) (n = 17) (Group 1) and tighter glycemic targets (121-180 mg/dl) (n = 51) (Group 2). We retrospectively analyzed arterial blood gas results taken at different perioperative time points from these patients. RESULTS We found that pH HCO3and base excess, serum sodium, potassium, calcium, and Hb were similar in both groups. CONCLUSION Our study showed that a tighter intraoperative glycemic control does not affect arterial blood gas parameters, serum electrolytes, or Hb when compared to the conventional glycemic control.

Abstract
AIM The aim of this study was to investigate blood glucose level of desflurane and sevoflurane on blood glucose in diabetic rats undergoing acute hyperglycemia. MATERIALS AND METHODS In this study, 30 male Wistar albino rats were included. Diabetes was induced by a single IP injection of streptozotocin. After the effects of chronic diabetes encountered, diabetic rats were randomly assigned into diabetic control (group DC), diabetic hyperglycemia group (group DH), diabetic hyperglycemia group with desflurane (group DH-D), and diabetic hyperglycemia group with sevoflurane (group DH-S) groups. The normoglycemic groups received an IP injection of the same amount of saline. Hyperglycemic diabetic rats were anaesthetized by desflurane 6 % or sevoflurane 2 % at a dose, by which minimal alveolar concentration (MAC) for rats would be one. The drugs were given for 4 hours within 100 % oxygen at a rate of 6 L.min-1. One hour after cessation of inhalation anesthesia, blood glucose levels were determined at 1st, 4th and 24th hours. 24 hours after the anaesthesia. RESULTS Serum glucose was detected to be significantly lower in Group C, when compared to Groups DC, DH, DH-D and DH-S (p = 0.002, p = 0.001, p = 0.002, p = 0.003, respectively). Blood glucose levels in the diabetic groups were similar at the end of 6 weeks period, after hyperglycemia and anaesthesia induction. CONCLUSION We found out that sevoflurane and desflurane administrations in hyperglycemic rats were both related with insignificant blood glucose level increase at early post anaesthesia period and at post anaesthesia 24th hours. We still think that patients undergoing anaesthesia protocols with acute hyperglycemia need relatively longer follow up periods (Tab. 1, Ref. 28).

Abstract
BACKGROUND Patients with severe chronic obstructive pulmonary disease (COPD) have impaired quality of life, but the relationship between their nutritional status and quality of life has not been established. The aim of this study was to determine the relationship between quality of life and nutritional status in hospitalized COPD patients. METHODS Demographic data, quality of life and nutritional status of 90 inpatients with a mean age of 68.76 ± 10.85 years were enrolled in the study. The Nutritional Risk Screening 2002 (NRS-2002) tool was used to evaluate their nutritional status. The quality of life was assessed using the Short Form-36 (SF-36) questionnaire. The correlation analysis was used for the relationship between SF-36 subscales and nutritional status variables. RESULTS Of the 90 COPD patients included in the study, 54.4 % were men, and 45.6 % were women. Moderate, severe, and very severe COPD were detected in 37.8 %, 38.9 %, and 23.3 % of the patients, respectively. At risk of malnutrition were 55.6 % of the 90 COPD patients, whereas 44.4 % were not. The scores for physical function, physical role functioning, pain, general health, emotional role functioning, vitality, social function, and mental function subscales were lower in the patients at risk of malnutrition (p <0.001). There was a statistically significant negative correlation between malnutrition score and the subscores of SF-36 related to physical function, physical role functioning, pain, general health, emotional role functioning, vitality, social function, and mental function (p <0.001). CONCLUSIONS COPD patients were found to have a high risk of malnutrition that adversely affects their quality of life. Therefore, the evaluation of the nutritional status of COPD patients should be an integral part of their clinical treatment plans aiming towards improving their quality of life.

Abstract
OBJECTIVE The aim of this study was to evaluate the mechanical behavior of different rigid fixation methods in mandibular angle fractures. MATERIALS AND METHODS Three different three-dimensional finite element models of the mandible were developed to simulate the biomechanical responses of titanium plates and screws. The fracture lines were fixed with double 4-hole straight, 4-hole square, and 5-hole Y plates with monocortical screws. 150 N incisal occlusal loads were simulated on the models. The commercial ANSYS software was utilized to calculate the Von Mises stresses on fixative appliances. RESULTS The highest Von Mises stress values were observed in the Y plate, whereas the lowest stress values have been found in the square plate. CONCLUSIONS The use of square plate led to better stability and lower mechanical stresses than other techniques.

We investigated effects of low and high doses of sugammadex (16 mg/kg versus 96 mg/kg) on renal tissue samples of streptozotocin-induced diabetic rats. MATERIAL AND METHODS Twenty-four Wistar albino rats were divided into 4 groups. Group C (control - 0.9 % NaCl), Group DC (diabetes control; 55 mg/kg streptozotocin, IP, only), Group DR-16S (diabetes-rocuronium - 16 mg sugammadex, IV.) and Group DR-96S (diabetes- rocuronium - 96 mg sugammadex, IV). Renal tissue histopathological evaluation and antioxidant status (measurements of MDA levels and NO activities) were studied. RESULTS Significantly higher levels of all inflammation parameters (inflammation, degeneration/necrosis, tubular dilatation, tubular cell degeneration, dilatation in Bowman's space, tubular hyaline casts, and lymphocyte infiltration) were found in the 96 mg/kg sugammadex group. Higher MDA tissue levels and lower NO activity were found in the 96 mg/kg sugammadex group. DISCUSSION We can conclude that high-dose (96 mg/kg) sugammadex administration resulted in significant renal tissue damage in diabetic rats. As a consequence, low doses of sugammadex have to be preferred in diabetic patients (Tab. 2, Fig. 4, Ref. 26).

Abstract
Iron overload is known to affect erythrocyte membrane properties and erythrocyte shape. We hypothesized that iron overload which directly affects the erythrocyte morphology may also interfere with erythrocyte deformability (ED). Exenatide, a glucagon like peptide -1 (GLP-1) analogue used in the treatment of diabetes, is known to have beneficial pleiotropic effects on endothelial function and blood flow which are different from its glucose-lowering effects. In our study we aimed to test the effect of iron overload on ED in a rat model (1) and to evaluate the effect of exenatide on ED in the same model (2). For this purpose, the animals were randomly divided into three groups, each containing 6 rats. Rats in the control group (Group C) were given intraperitoneal injections of saline as placebo. The second group (Group Fe) was given intraperitoneal iron dextran (60 mg/kg/day) five days a week for 4 weeks to develop iron overload. The third group (Group Fe +E) received subcutaneous injections of 10 mcg exenatide (Byetta® Lilly Pharma) in two divided doses for 4 weeks in addition to iron dextran. We observed that ED index was significantly higher in Group Fe when compared to Group C and Group Fe+E (p Keywords: erythrocyte deformability, iron, exenatide.

Abstract
In this study, a methodology based on Fourier-transform infrared spectroscopy and principal component analysis and partial least square methods is proposed for the analysis of blood plasma samples in order to identify spectral changes correlated with some biomarkers associated with schizophrenia and bipolarity. Our main goal was to use the spectral information for the calibration of statistical models to discriminate and classify blood plasma samples belonging to bipolar and schizophrenic patients. IR spectra of 30 samples of blood plasma obtained from each, bipolar and schizophrenic patients and healthy control group were collected. The results obtained from principal component analysis (PCA) show a clear discrimination between the bipolar (BP), schizophrenic (SZ) and control group' (CG) blood samples that also give possibility to identify three main regions that show the major differences correlated with both mental disorders (biomarkers). Furthermore, a model for the classification of the blood samples was calibrated using partial least square discriminant analysis (PLS-DA), allowing the correct classification of BP, SZ and CG samples. The results obtained applying this methodology suggest that it can be used as a complimentary diagnostic tool for the detection and discrimination of these mental diseases.

Abstract
This paper describes the presence of a 15.4 Mb deletion of 14q12→q21.2 and a 550-KB deletion of 18p11.23 in a patient with an apparently balanced translocation between chromosomes 14 and 18 [t( 14; 18) (ql2; pi 11)]. The patient had developmental delay, truncal hypotonia, hyperreflexia and spasticity of the lower extremities, prominent forehead, fullness of the periorbital region, hypertelorism, upslanted palpebral fissures, systagmus, a depressed nasal bridge, down-turned conrners of the mouth, a prominent philtrum, thin upper lip, pointed chin, and deep palmar creases. Cranial MRI revealed agenesis of the corpus callosum, diffuse cerebral atrophy, and enlargement of the third and lateral ventricles. Here, we review and compare published cases with proximal 14q deletions to establish a genotype-phenotype correlation according to the deleted regions involving the 14q12, 14q13, 14q21, and 14q22q23. We also examined the literature to find cases with deleted regions overlapping the deletion in our patient to establish a clinical spectrum in proximal 14q deletions.

Abstract
BACKGROUND Ischemia reperfusion injury (I/R) in lower extremity is a frequent and important clinical phenomenon. Protective effect of alprostadil on local and distant organ injury due to I/R has been well-documented but its effect on erythrocyte deformability needs further investigation. Our aim was to investigate the effect of alprostadil on erythrocyte deformability in infrarenal aorta of rats undergoing I/R. MATERIALS AND METHODS Our study was conducted with 18 Wistar albino rats. Rats were divided into 3 groups; randomized control group (group C; n=6), I/R group without alprostadil (group I/R; n=6) and I/R group with alprostadil 20 mcg.kg(-1), intraperitoneal (group I/R-A; n=6). Packs of erythrocytes were prepared from heparinized blood samples and deformability measurements were done. RESULTS Comparisons of the control and I/R-A groups revealed similar results (p=0.240). The values of the IR group were significantly higher than those of the control and IR-A groups (p=0.009, p=0.026, respectively). CONCLUSION In our study, we detected unfavourable effects of I/R on erythrocyte deformability, which may lead to disturbance in blood flow and hence tissue perfusion in infrarenal rat aorta. We also found that alprostadil had beneficial effects by reversing undesirable effects of I/R (Fig. 1, Ref. 22).
