Abstract
OBJECTIVE This study aimed to examine the factors linked to the development of clinically significant pancreatic fistulas following distal pancreatectomy (DP) and to assess the efficacy of suture ligation of the main pancreatic duct. PATIENTS AND METHODS A single-center retrospective study was performed on the medical records of 82 patients who underwent DP in our institution between January 2011 and December 2019. RESULTS There were 28 males (34.1%) and 54 females (65.9%). The patients' age ranged from 18 to 86 years (median: 55.5 years). Indications for DP included primary pancreatic disease (n=63, 76.8%) and non-pancreatic disease (n=19, 23.2%). Postoperative mortality and morbidity rates were 3.7% and 48%, respectively. Pancreatic parenchymal closure was accomplished by a hand-sewn technique or mechanical stapling in 89 and 13 patients, respectively. Identification of the pancreatic duct and suture ligation was performed in 46 patients (56.1%). Pancreatic fistula was developed in 20 patients (24.4%); 12 fistulas were classified as Grade B, and 8 as Grade C. Biochemical leaks (Grade A) were identified in 8 patients (9.8%). Multivariate analysis indicated that failure to ligate the main pancreatic duct was the only variable associated with an increased risk for pancreatic leak (p=0.031; odds ratio=0.233; 95% confidence interval, 0.062-0.879). CONCLUSIONS Pancreatic leak remains a common complication after DP. The incidence of leaks is reduced significantly when the main pancreatic duct is identified and directly ligated during DP.

Abstract
Precision/personalized medicine in oncology has two key pillars: molecular profiling of the tumors and personalized reporting of the results in ways that are clinically contextualized and triangulated. Moreover, neurosurgery as a field stands to benefit from precision/personalized medicine and new tools for reporting of the molecular findings. In this context, glioblastoma (GBM) is a highly aggressive brain tumor with limited treatment options and poor prognosis. Precision/personalized medicine has emerged as a promising approach for personalized therapy in GBM. In this study, we performed whole exome sequencing of tumor tissue samples from six newly diagnosed GBM patients and matched nontumor control samples. We report here the genetic alterations identified in the tumors, including single nucleotide variations, insertions or deletions (indels), and copy number variations, and attendant mutational signatures. Additionally, using a personalized cancer genome-reporting tool, we linked genomic information to potential therapeutic targets and treatment options for each patient. Our findings revealed heterogeneity in genetic alterations and identified targetable pathways, such as the PI3K/AKT/mTOR pathway. This study demonstrates the prospects of precision/personalized medicine in GBM specifically, and neurosurgical oncology more generally, including the potential for genomic profiling coupled with personalized cancer genome reporting. Further research and larger studies are warranted to validate these findings and advance the treatment options and outcomes for patients with GBM.

Abstract
BACKGROUND Although lower airway hyperresponsiveness is present in approximately one in three patients with allergic rhinitis (AR), the underlying mechanism remains unclear. To evaluate nasal patency and pulmonary functions in AR independently of the presence of asthma and to investigate the relationships between these and nasal oxidative stress parameters and endothelial damage. METHODOLOGY Seventy adolescents with AR (AR group - 27 with asthma and 43 without asthma) and 30 healthy controls (HC group) were included in this prospective, cross-sectional study. Endocan and oxidative biomarkers [total oxidant status (TOS), total antioxidant status (TAS), and oxidative stress index (OSI)] in nasal lavage fluid specimens; peak nasal inspiratory flow (PNIF); fractional exhaled nitric oxide (FeNO), and impulse oscillometry (zR5, zR20, and R5-20 for resistance and zX5 and zX20 for reactance) were investigated. RESULTS Nasal endocan, TOS, and OSI values were higher in the AR group and TAS in the HC group. There was no difference between AR groups with and without asthma in terms of nasal endocan and oxidative biomarkers. FeNO levels and airway resistance (zR5, zR20, and R5-20) were higher in the AR group than in the HC group. However, there was no difference between the groups in PNIF. X5 was higher among the AR without asthma than in the other groups. Correlation between OSI and R5-20 was observed in the AR group. In the linear regression model, (logged) OSI was significantly predicted (logged) R5-20. CONCLUSIONS The airways of adolescents with AR without asthma were as much affected as those of the AR with asthma, and this effect was associated with nasal endothelial damage and an increase in oxidative stress.

Abstract
OBJECTIVE To evaluate the validity and reliability of the Fonseca anamnestic index (FAI) over time in Turkish females. METHODS Four hundred-fourteen patients who visited the otorhinolaryngology clinic were initially included in the study between January 1, 2018 and January 1, 2019. The Turkish version of the FAI is a self-report instrument that was completed by all of the patients after a brief explanation from the clinician. Cronbach's alpha was calculated using data from the first questionnaire. RESULTS The results of the first assessment showed 243 patients had no TMD (58.7%), 40 had mild TMD (9.7%), 87 had moderate TMD (21%), and 44 had severe TMD (10.6%). At the second assessment, the respective values were 243 (58.7%), 37 (8.9%), 98 (23.7%), and 36 (8.7%). The internal consistency of the first test was high. CONCLUSION The FAI can be used to collect a large amount of data easily, at minimal cost.

Abstract
PURPOSE OF THE STUDY Soft tissue sarcomas of the popliteal fossa are extremely rare tumors of mesenchymal origin accounting for 3%-5% of all extremity sarcomas. However, data regarding the tumor type, neurovascular involvement, and administration of radiation therapy before or after resection are limited. This study aimed to report on popliteal fossa sarcomas analyzing data from two institutions based on a relatively large patient sample. MATERIAL AND METHODS Twenty-four patients (80%; 9 men and 15 women) with a popliteal fossa soft tissue sarcoma were included in this study. The reviewed patient data included sex, age, duration of complaints, interval to diagnosis, radiology, pre- and postoperative biopsy, tumor histology, surgery type, complications, and pre- and postoperative oncologic and functional outcomes. The minimum follow-up was 24 months. RESULTS The mean age of the patients was 48 ± 21.23 (range 3-72) years at the time of diagnosis. The mean follow-up was 41.79 ± 16.97 (range 24-120) months. The most common histological diagnoses were synovial sarcoma (6 patients), hemangiopericytoma (2 patients), soft tissue osteosarcoma (2 patients), unidentified fusiform cell sarcoma (2 patients), and myxofibrosarcoma (2 patients). Local recurrence after limb salvage was observed in six patients (26%). At the latest followup, 2 patients died of the disease, 2 patients were still alive with progressive lung disease and soft tissue metastasis, and the remaining 20 patients were free from the disease. CONCLUSIONS Microscopically positive margins may not be an absolute indication for amputation. Also, negative margins do not provide a guarantee that local recurrence will not occur. Lymph node or distant metastasis may be predictive factors for local recurrence rather than positive margins. Key words: fossa poplitea, sarcoma.

Abstract
Dental pain is a persistent, detrimental public health issue that requires a better understanding of the mechanisms of tooth pain and inflammation in order to develop more effective treatments. Calcitonin gene-related peptide (CGRP) and dental pulp cells are promising candidates for mediating tooth pain and generating reparative dental tissues, respectively, but their behavior in the context of pulpitis remains elusive. The mouse incisor requires Sonic hedgehog (Shh) secreted from sensory nerves to continuously regenerate. However, it is unknown whether sensory nerves also regulate the comparatively nonregenerative mouse molar through CGRP and Shh. This is an important knowledge gap to fill since mouse incisors differ biologically from human teeth, while mouse and human molars are similar. In this work, we identified that molar pulp cells express CGRP receptor and Gli1, a Hedgehog (Hh) signaling protein found to label a dental stem cell population in the mouse incisor. We also observed in a mouse molar injury model that Hh signaling was activated and Shh expression was upregulated in vivo. We then determined in vitro that Shh and CGRP regulate differentiation of primary mouse molar and incisor pulp cells and a human dental pulp stem cell line. Furthermore, conditioned media from stimulated sensory neurons induced Hh signaling activation and inflammatory gene expression in primary molar pulp cells, which was abolished by inhibition of either Shh or CGRP. Our results suggest that CGRP and Shh signaling may promote an inflammatory response after injury in the molar and that activated sensory nerves secrete CGRP and Shh to regulate molar pulp cell expansion and differentiation into odontoblast-like cells for dentin repair. Thus, CGRP/Shh signaling should be considered for new strategies that seek to manage pain or dentin regeneration in the molar.

Abstract
BACKGROUND Traumatic brain injury (TBI) is increasingly recognised as being responsible for a substantial proportion of the global burden of disease. Neurosurgical interventions are an important aspect of care for patients with TBI, but there is little epidemiological data available on this patient population. We aimed to characterise differences in casemix, management, and mortality of patients receiving emergency neurosurgery for TBI across different levels of human development. METHODS We did a prospective observational cohort study of consecutive patients with TBI undergoing emergency neurosurgery, in a convenience sample of hospitals identified by open invitation, through international and regional scientific societies and meetings, individual contacts, and social media. Patients receiving emergency neurosurgery for TBI in each hospital's 30-day study period were all eligible for inclusion, with the exception of patients undergoing insertion of an intracranial pressure monitor only, ventriculostomy placement only, or a procedure for drainage of a chronic subdural haematoma. The primary outcome was mortality at 14 days postoperatively (or last point of observation if the patient was discharged before this time point). Countries were stratified according to their Human Development Index (HDI)-a composite of life expectancy, education, and income measures-into very high HDI, high HDI, medium HDI, and low HDI tiers. Mixed effects logistic regression was used to examine the effect of HDI on mortality while accounting for and quantifying between-hospital and between-country variation. FINDINGS Our study included 1635 records from 159 hospitals in 57 countries, collected between Nov 1, 2018, and Jan 31, 2020. 328 (20%) records were from countries in the very high HDI tier, 539 (33%) from countries in the high HDI tier, 614 (38%) from countries in the medium HDI tier, and 154 (9%) from countries in the low HDI tier. The median age was 35 years (IQR 24-51), with the oldest patients in the very high HDI tier (median 54 years, IQR 34-69) and the youngest in the low HDI tier (median 28 years, IQR 20-38). The most common procedures were elevation of a depressed skull fracture in the low HDI tier (69 [45%]), evacuation of a supratentorial extradural haematoma in the medium HDI tier (189 [31%]) and high HDI tier (173 [32%]), and evacuation of a supratentorial acute subdural haematoma in the very high HDI tier (155 [47%]). Median time from injury to surgery was 13 h (IQR 6-32). Overall mortality was 18% (299 of 1635). After adjustment for casemix, the odds of mortality were greater in the medium HDI tier (odds ratio [OR] 2·84, 95% CI 1·55-5·2) and high HDI tier (2·26, 1·23-4·15), but not the low HDI tier (1·66, 0·61-4·46), relative to the very high HDI tier. There was significant between-hospital variation in mortality (median OR 2·04, 95% CI 1·17-2·49). INTERPRETATION Patients receiving emergency neurosurgery for TBI differed considerably in their admission characteristics and management across human development settings. Level of human development was associated with mortality. Substantial opportunities to improve care globally were identified, including reducing delays to surgery. Between-hospital variation in mortality suggests changes at an institutional level could influence outcome and comparative effectiveness research could identify best practices.

Abstract
Innovation roadmaps are important, because they encourage the actors in an innovation ecosystem to creatively imagine multiple possible science future(s), while anticipating the prospects and challenges on the innovation trajectory. In this overarching context, this expert review highlights the present unmet need for therapeutic innovations for pituitary neuroendocrine tumors (PitNETs), also known as pituitary adenomas. Although there are many drugs used in practice to treat PitNETs, many of these drugs can have negative side effects and show highly variable outcomes in terms of overall recovery. Building innovation roadmaps for PitNETs' treatments can allow incorporation of systems biology approaches to bring about insights at multiple levels of cell biology, from genes to proteins to metabolites. Using the systems biology techniques, it will then be possible to offer potential therapeutic strategies for the convergence of preventive approaches and patient-centered disease treatment. Here, we first provide a comprehensive overview of the molecular subtypes of PitNETs and therapeutics for these tumors from the past to the present. We then discuss examples of clinical trials and drug repositioning studies and how multi-omics studies can help in discovery and rational development of new therapeutics for PitNETs. Finally, this expert review offers new public health and personalized medicine approaches on cases that are refractory to conventional treatment or recur despite currently used surgical and/or drug therapy.

Abstract
Intermediate-grade meningeal melanocytomas (IGM) are rarely reported tumors and has not been reported in childhood yet. They are spaculated to have more agressive clinical behavior and their best management options has not been defined. Here we report a 19 months old child being the first case in English literature having IGM. Pre-operative diagnosis was confusing since patient history was unclear and radiological features resembled a growing skull fracture or a subtype of congenital parietal bone agenesis. An area of 5x7 cm dura was found to be dark grey and black in colour and excised but the operation was complicated with brain edema and swelling, and a second operation for reconstruction and dural repair was needed. Of the 16 patients reported in adults, 14 showed a high recurrence rate without adjuvan radiotherapy, and 2 did not showed recurrence with adjuvan radiotherapy. Our patient did not have adjuvan radiotherapy since he was just 19 months old at the time his diagnosis and did not show recurrence until now at 24 months of follow-up. Close monitoring with radiological imaging is of paramount importance.

Abstract
BACKGROUND/PURPOSE There has been a rapid increase in the use of non-vitamin K-antagonist oral anticoagulants (NOAC). Current guidelines recommend dose adjustments be made in accordance with certain criteria for each NOAC. This study is aimed at determining whether or not NOAC were prescribed for non-valvular atrial fibrillation (AF) in guideline-recommended doses in community-dwelling older adults. METHODS Older adults taking NOAC for non-valvular AF presenting to a cardiology outpatient clinic for the first time were included in the study. The NOAC dose for each patient was assessed based on the recommendations of the European Society of Cardiology and were categorized as appropriate or inappropriate (low or high dose). The patients were also evaluated for demographic data, diseases, CHA2DS2-VASc score, HASBLED score, frailty and falls in the previous year. RESULTS A total of 302 older adults were included in the study, with a mean age of 75.5 ± 7.5 years. One hundred eighty-four patients (60.9%) were found to be on appropriate doses of NOAC, while 109 (36.1%) were on inappropriately low doses and nine (2.98%) were on inappropriately high doses. Accordingly, 39.1% of the AF patients were found to be on inappropriate doses of NOAC, 92.4% of which were inappropriately low. A multivariate logistic regression analysis revealed that the only factor associated with inappropriate low-dose NOAC use was patient age (OR = 1.061, 95% CI = 1.009-1.116, p = 0.022). CONCLUSION Our study suggests that the inappropriate use of lower dose NOAC may emerge as a significant problem in outpatient older adults. This inappropriate practice seems to be associated with older age rather than the diseases, CHA2DS2-VASc/HASBLED scores, frailty and presence of falls.

Abstract
Phyllodes tumors are uncommon breast neoplasms that constitute of 1-2% of breast malignancies. The tumor can mimic fibroadenoma clinically, radiologically and histologically. Ductal carcinoma in-situ in the epithelial component of phyllodes tumor is very rare. When ductal carcinoma in-situ is detected within the specimen, the management of treatment changes completely. We report a rare case of low grade ductal carcinoma in-situ arising in a malignant phyllodes tumor in a 55-year-old female patient.

Abstract
Objective To compare the use of a piezosurgery expander and conventional chisel/osteotome on primary implant stability. Materials and Methods Twenty fresh ribs were divided into two main groups; group P and group C. In group P, bone expansion was performed using piezosurgery. In group C, bone expansion was performed using conventional chisel osteotomy. In both groups, the implants were inserted into the ribs after bone expansion. After implant placement, primary stability values were evaluated from the bucco-lingual (B-L) and mesio-distal (M-D) sides of the implant. Results The primary stability values on the B-L side of both implants in group P were significantly higher than in group C (P < 0.05). Conclusion The use of piezo-expanders in the alveolar split technique has better effects on primary implant stability compared with the conventional technique.

Abstract
AIM To identify the copy number variations that are specific to myxopapillary ependymomas (MPEs) of the cauda equina. MATERIAL AND METHODS The patient cohort included five patients who underwent resection of histologically confirmed MPEs. Tumor samples collected during surgery and stored in liquid nitrogen as well as corresponding blood samples collected were analyzed. Genomic DNA from the venous blood and tumor samples was obtained using standard techniques and hybridized to a Cytoscan 750K Array in accordance with the manufacturer’s introductions. RESULTS As a novel finding, amplification on chromosome 14q32.33 was detected in all tumor and blood samples, except one tumor sample. All tumor tissues also showed amplification on chromosomes 5, 7, 9, and 16. CONCLUSION Although further studies with larger cohorts are required to identify genes involved in MPE tumorigenesis and to validate our results, these findings provide a basis for advanced molecular biological and genetic studies of MPEs.

Abstract
Background T‐wave peak‐to‐end interval (TPEI) is a measure of repolarization dispersion on surface electrocardiogram (ECG). TPEI has been reported as a prognostic parameter with heart disorders. In this study, we aimed to evaluate the relationship between echocardiogram‐derived right heart parameters, right heart catheterization (RHC) measurements, and TPEI in patients with precapillary pulmonary arterial hypertension (PAH). Methods Thirty‐eight patients (29 females and 9 males, mean age of 54.9 ± 10.9 years) who had undergone RHC for a preliminary diagnosis of pulmonary hypertension (PH) were included in the study. We performed transthoracic echocardiography (TTE), and resting 12‐lead ECG was recorded before RHC. TPEI was measured from leads of V1‐V6, DII, DIII, and aVF, and these values are averaged to obtain the global TPEI. Results Duration of TPEI was significantly correlated with mean PAP, pulmonary vascular resistance (PVR), and cardiac index (CI). Longer TPEI was associated with higher N terminal probrain natriuretic peptide (NT pro‐BNP) level, lower 6‐min walk distance (6MWD), and lower tricuspid annular plane systolic excursion (TAPSE). Conclusion Prolongation of TPEI could be a new predictor of adverse outcome in PAH and may provide additional prognostic information for patients with PAH.

Abstract
Objective: To evaluate the effects of caesarian section (CS) versus vaginal birth (VB) delivery techniques on results from neonatal hearing screening tests (NHSTs).Design: Retrospective analysis.Study sample: A total of 10,767 neonates divided into two groups according to delivery technique underwent NHSTs. Those who failed TEOAE or AABR were sent for diagnostic ABR examination.Results: A total of 5620 of 6044 (92.9%) of the neonates in the CS group passed the TEOAE test bilaterally and 424 (7.1%) failed either unilaterally or bilaterally. In the VB group, 4496 of 4723 (95.1%) neonates passed the TEOAE test bilaterally, while the remaining 227 (4.9%) failed the test either unilaterally or bilaterally. Bilateral passing rate of TEOAE test results was significantly higher in the VB group than the CS group (p < 0.05). The AABR failure rate (unilaterally or bilaterally) was 1% in the CS group, which was significantly higher than that in the VB group (0.6%). Diagnostic ABR bilateral pass rate was not statistically different between the groups.Conclusions: Delivery method was shown to affect the results of NHSTs. We found that the rates of failing the TEOAE and screening AABR examinations were higher among neonates born by CS compared to VB.

Abstract
Objective Irrigation with saline is one of the essential methods for reducing the heat generated during dental implant osteotomy. High irrigation volume impairs visibility of the surgical field, thus complicates the surgery. In this study, we aimed to determine the optimal irrigation volume for heat reduction during dental implant drilling. Materials and Methods Thirty-two implant osteotomies were prepared on four fresh cow ribs. Heat generated during the final implant drilling was measured both with infrared thermography and thermocouple method. Initial and maximum temperatures were measured at four different irrigation volumes; 32, 44, 56, and 68 ml/min. Results Both measurement methods showed that the amount of temperature rise is associated with the irrigation volume during implant drilling. There is no further decrease in temperature rise above irrigation volume of 56 ml/min. Conclusion Saline irrigation with 56 ml/min provides sufficient heat reduction during dental implant drilling and higher irrigation volumes are not necessary.

Abstract
UNLABELLED We evaluated the effects of zoledronic acid (ZA) therapy on electrocardiographic (ECG) parameters for the first time in the literature. Measurements were performed on ECGs obtained before and after ZA infusion on the same day as well as 1 month after the infusion. ZA infusion did not have any short- or long-term effect on any parameter that might be associated with the tendency for atrial fibrillation or ventricular arrhythmias. INTRODUCTION The aim of the present study was to evaluate the early and late effects of ZA therapy on ECG parameters which might be associated with the tendency for atrial and ventricular arrhythmias. METHODS Consecutive patients with osteoporosis who were admitted to our clinic between December 2013 and December 2014 and who were scheduled to receive ZA infusion constituted our study population. Twelve-lead surface ECGs were obtained from all patients before and after ZA infusion on the same day as well as 1 month after the infusion. All ECG parameters were measured and compared with each other for each patient. RESULTS Data of 100 patients were used in the analysis (9 male; 70.5 ± 11.6 years of age). There were no significant differences between repeated measurements regarding pmax, pmin, and p dispersion values. QT max and QT min values were significantly increased after infusion; however, there were no significant changes in QT dispersion, Tp-e interval, and Tp-e dispersion values. CONCLUSIONS ZA infusion did not affect P wave dispersion both at the immediate post-infusion period and 1 month after infusion. QT values were significantly increased early after ZA infusion; however, there were no significant differences in parameters reflecting disparity of ventricular recovery times and transmural dispersion of ventricular repolarization. Based on these observations, it may be suggested that ZA infusion did not have any short- or long-term effect on any parameter that might be associated with the tendency for atrial fibrillation or ventricular arrhythmias.

Abstract
AIM To analyse the incidence of bone fracture of breast cancer patients with isolated bone metastasis and its effect on survival. We tried to find an answer to the question of "Can the development of bone fracture be predicted?" METHODS Between 1993-2006, 139 breast cancer patients with isolated bone metastasis were examined. Patients were divided into two groups depending on the development of pathologic bone fracture. RESULTS Fractures were developed in 41 patients (29.5%)within 41 months of follow-up. The locations of pathologic bone fracture were vertebral fracture in 26 patients (63.4%),femur fracture in 11 patients (26.8%), and hip fracture in four patients (9.8%). Fracture rates in hormone sensitive and resistant patients were 31.2% and 14.3%, respectively. The fracture rates in 13 triple negative and non triple negative patients were 7.7% and 31.4%, respectively (p=0.07). High CA 15-3 levels at the time of metastasis in patients with and without fractures were 68.4% and 61.1%, respectively. The risk for fracture was also high in Her2-neu positive patients (38.7% vs. 26.5%). While the incidence of fracture with the presence of one factor mentioned above was 22.2%, it was increased to 36.1% in the presence of two or three factors(p=0.13). Median survivals of the patients with and without fractures were 48 and 39 months, respectively (p= 0.65). CONCLUSION Hormone sensitivity, high CA 15-3 levels and positive Her2-neu status are slight risk factors for bone fractures. Survival was not different in patients with or without bone fractures.

Abstract
The evaluation of syncope in severe aortic stenosis usually requires intense work-up. Mechanical obstruction should not always be implicated as the underlying cause of syncope. Syncope at rest may be rarely associated with ventricular arrhythmias. We present a patient with severe aortic stenosis who experienced syncopal events due to torsade de pointes.

Abstract
Turkey is the sixth largest producer of cotton in the world. Two of the most commonly applied pesticides used in cotton production are trifluralin and endosulfan. Although both are very effective at controlling pests, their persistence in the environment poses risks to human health and the environment. Four loam soils and one silty-loam soil were studied to evaluate the persistence of trifluralin and endosulfan in relation to soil characteristics. Degradation with trifluralin reached as high as 70% of the applied doses. Soils with the highest organic matter content had the lowest degradation rate, indicating a tighter sorption of trifluralin. Endosulfan degradation was a function of soil type and the specific isomer, with beta-endosulfan depicting the highest degradation.

Abstract
Comprehensive in silico studies, based on the total fugu genome database, which was the first to appear in fish, revealed that torafugu Takifugu rubripes contains 20 sarcomeric myosin heavy chain (MYH) genes (MYH genes) (Ikeda et al., 2007). The present study was undertaken to identify MYH genes that would be expressed in adult muscles. In total, seven MYH genes were found by screening cDNA clone libraries constructed from fast, slow and cardiac muscles. Three MYH genes, fast-type MYH(M86-1), slow-type MYH(M8248) and slow/cardiac-type MYH(M880), were cloned exclusively from fast, slow and cardiac muscles, respectively. Northern blot hybridization substantiated their specific expression, with the exception of MYH(M880). In contrast, transcripts of fast-type MYH(M2528-1) and MYH(M1034) were found in both fast and slow muscles as revealed by cDNA clone library and northern blot techniques. This result was supported by in situ hybridization analysis using specific RNA probes, where transcripts of fast-type MYH(M2528-1) were expressed in fast fibres with small diameters as well as in fibres of superficial slow muscle with large diameters adjacent to fast muscle. Transcripts of fast-type MYH(M86-1) were expressed in all fast fibres with different diameters, whereas transcripts of slow-type MYH(M8248) were restricted to fibres with small diameters located in a superficial part of slow muscle. Interestingly, histochemical analyses showed that fast fibres with small diameters and slow fibres with large diameters both contained acid-stable myofibrillar ATPase, suggesting that these fibres have similar functions, possibly in the generation of muscle fibres irrespective of their fibre types.

Abstract
Dialysis and kidney transplant patients display endothelial dysfunction. Previous studies concerning comparisons of endothelial function in dialysis and kidney transplant patients included subjects with cardiovascular risk factor(s) that alone may lead to endothelial dysfunction. In this study, we compared endothelial function between dialysis and transplant patients who did not show known cardiovascular risk factors that lead to endothelial dysfunction. We studied age- and gender-matched cohorts: 30 hemodialysis (HD), 30 peritoneal dialysis (PD), and 30 kidney transplant patients. We also included 20 age- and gender-matched healthy controls. We assessed the endothelial function of patients and controls by a noninvasive technique. Serum biochemistry profiles of patients were also similar to controls in terms of lipid profile and fasting blood glucose level. Although mean FMD% levels of HD and PD patients were similar (6.6% +/- 3.1% vs 6.8% +/- 3.0%, P > .05), the mean percent of flow-mediated endothelium-dependent dilatation (FMD%) level in transplant patients was higher than those in HD or PD patients (10.50% +/- 3.0% vs 6.6% +/- 3.1% and 6.8% +/- 3.0%, respectively; P < .01). In addition, the mean FMD% level in healthy controls was higher than those in HD, PD, and transplant patients (14.0% +/- 2.3% vs 6.6% +/- 3.1%, 6.8% +/- 3.0% and 10.50% +/- 3.0%; P < .01, respectively). In conclusion, endothelial functions in transplant patients were better than those in dialysis patients.

Abstract
BACKGROUND To provide postoperative analgesia by spinal anesthesia, we compared the quality of analgesia and side effects of two doses of morphine added to ropivacaine in kidney donors. MATERIALS AND METHODS Thirty renal donors underwent nephrectomy under standard general anesthesia. After the operation, the patients were randomly allocated into two groups of intrathecal doses for spinal anesthesia: the 0.5 group (n = 15) received a total volume of 4 mL including 0.5 mg morphine, 10 mg ropivacaine, and 0.9% NaCl, and the 0.3 group (n = 15), a total volume of 4 mL including 0.3 mg morphine, 10 mg ropivacaine, and 0.9% NaCl. After extubation, an intravenous (IV) morphine protocol was initiated by a patient-controlled analgesia pump to provide sufficient spinal analgesia. RESULTS In the 0.3 group, the IV morphine consumption was significantly higher, namely, 14.60 +/- 7.57 times versus 4.60 +/- 10.14 times for the 0.5 group (P = .005). The total amount of morphine was 7.80 +/- 5.40 mg in the 0.5 group and 13.53 +/- 5.30 mg in the 0.3 group (P < .05). Postoperative side effects of nausea and vomiting were higher among the 0.3 group (P < .05). CONCLUSIONS In the 0.5 group, the quality of analgesia was better than in the 0.3 group. The need for IV morphine was less in the 0.5 group. Also, side effects like nausea and vomiting were less, so better analgesia in the postoperative period was obtained with the 0.5 mg morphine solution.

Abstract
OBJECTIVES Mycophenolate mofetil (MMF) has become more widely prescribed in recent years, but its adverse effects on the gastrointestinal system and bone marrow restrict its use in certain settings. The aim of this study was to compare the demographic features and clinical data for 173 renal transplant recipients who received tacrolimus (TAC) plus 1 g/d MMF (group I, n = 112) versus TAC plus 2 g/d MMF (group II, n = 61 patients) over a 2-year period. Each patient received similar TAC doses. METHODS We compared demographic data and clinical data for each case: acute rejection (AR) episodes, chronic rejection (CR) episodes, death, graft loss, development of posttransplantation diabetes mellitus (PTDM), and posttransplantation hypertension rates. RESULTS Demographic features were similar. There were also no significant differences between groups I and II with respect to number of AR episodes (17/112 vs 12/61, respectively), number of CR episodes (4/112 vs 1/61, respectively), PTDM, and hypertension rate (P > .05). Kaplan-Meier survival analysis revealed 2-year graft survival rates of 94% in group I versus 83% in group II. The corresponding 2-year patient survival rates were 100% in group I versus 91% in group II. The graft survival and patient survival rates in group I were significantly higher than those in group II (log-rank 0.005 and 0.001, respectively). CONCLUSIONS The 2-year graft and patient survival rates for the renal transplant recipients in this study suggest that the combination of a full TAC dose with 1 g/d MMF is a better choice than 2 g/d MMF.

Abstract
INTRODUCTION One treatment option for patients with type 1 diabetes mellitus with end-stage nephropathy is combined pancreas-kidney transplantation, which can be performed either simultaneously (SPK) or following kidney transplantation (PAK). PATIENTS AND METHODS Between February 2003 and November 2004, 14 patients, including 10 males and 4 females of overall mean age of 31.3 +/- 6.1 years (range, 23-44 years), presented with end-stage renal disease secondary to type 1 diabetes mellitus. Five patients (35.7%) received SPK; 7 patients (50%) received PAK; and 2 patients (14.3%) received simultaneous pancreas and living-related kidney (SPLK) transplantations. RESULTS Two among 14 pancreas grafts were lost in the early postoperative period secondary to venous thrombosis despite anticoagulation including 1 with poor portal drainage. Insulin therapy was reinitiated in 1 patient after a second rejection episode in the seventh postoperative month. By the ninth median follow-up month (range, 1-21 months), all kidney grafts were functioning. CONCLUSION Our single-center short-term experience with 14 consecutive kidney-pancreas transplantations suggests that while the pancreas transplant is effective and safe to reestablish normoglycemia, this transplant creates additional surgical and immunosuppressive stresses on the patient.

Abstract
Lack of expansion of the deceased donor supply has resulted in a severe shortage of organs worldwide. Spousal donors are one possible alternative organ source for patients on the kidney transplant waiting list. Despite human lymphocyte antigen (HLA) matching between recipients and unrelated donors being poor, the reported survival rates for these grafts, including spouses, are comparable to those for grafts from living related donors and higher than those for deceased donor kidneys. In 2000, our renal transplantation program began accepting living donor-recipient pairs with one or zero HLA matches. The purpose of this study was to assess this policy for accepting living unrelated donors. The 3-year graft survival rates for the transplants from living unrelated donors were similar to that for transplants from living related donors (log-rank = 0.078). The number of HLA mismatches did not significantly influence the survival rates for either of these groups of living donor transplants. Multivariate analysis revealed that dialysis duration (P = .057) and recipient age (P = .066) negatively influenced patient survival in living donor kidney transplantation. The graft and patient survival rates for the donor transplantations were higher than those for deceased donor transplantations. In light of these findings and considering the increasing problem of organ shortage, we conclude that living unrelated kidney transplantation should be performed, with strict guidelines. Spousal donation is the most favorable form of living unrelated renal transplantation.

Abstract
The aim of the present study was to investigate sex differences in learning strategies and to elucidate the mechanisms, which may underlie these differences. In two separate experiments, rats were presented with different strategies that could be employed to learn the position of a platform in a water maze (WM); furthermore, rats received treatments that could influence these strategies. In the first experiment, we demonstrated that the response-learning paradigm can be applied to the WM and can be compared with visually cued learning and reversal learning. Naïve rats of either sex could acquire this protocol relatively easily. On the probe trial, where the rats are presented with a choice between using response versus visually cued learning, initially response learning was preferred, however, during these experiments, laterality emerged as a significant factor and rats trained to turn right had difficulty in reversing the learned pattern to find the platform. The second part of our study evaluated the effects of nicotine and nitric oxide synthase (NOS) inhibition on the aforementioned parameters. Drug treatments impaired acquisition compared to saline treatments and the effect was more pronounced with NOS inhibition. During the probe trial, while NOS inhibition enhanced the right-side bias in both sexes, nicotine treatment had the same effect only in males. In conclusion, naïve rats can acquire place learning using visible cues or response learning; however, there is a right side bias in both sexes and the laterality effect is more pronounced in male rats. In drug-treated animals, while NOS inhibition enhances laterality (right bias) in both sexes similarly, nicotine modifies the cognitive strategy in a sexually dimorphic manner by augmenting the right bias only in male rats.

Abstract
We aimed to determine the correlations between standard clinicopathological factors and expression of c-erbB-2 and p53 proteins, and to investigate the significance of these variables in relapse and disease-free survival (DFS) in breast carcinoma patients. Data from 200 patients who had undergone mastectomy for breast carcinoma were evaluated. Significant correlations were found between c-erbB-2 positivity and high histological grade (grade 3) tumour, p53 positivity and high grade tumour, and age < 60 years and oestrogen receptor negativity. Twenty-six patients (13%) developed a recurrence. Disease relapse was more frequent in patients who had axillary lymph node (ALN) metastasis, high grade tumour, c-erbB-2 positivity and p53 positivity; these variables were also associated with a shorter DFS. The effects of ALN metastasis and p53 positivity were significant. In conclusion, ALN metastasis and p53 positivity were important factors for predicting disease relapse in mastectomy-treated breast carcinoma patients; other clinicopathological criteria and c-erbB-2 positivity were not predictive.
