Abstract
Metabolic syndrome (MetS) is a prevalent public health problem. Uric acid (UA) is increased by MetS. We investigated whether administration of UA and 10% fructose (F) would accelerate MetS formation and we also determined the effects of irisin and exercise. We used seven groups of rats. Group 1 (control); group 2 (sham); group 3 (10% F); group 4 (1% UA); group 5 (2% UA); group 6 (10% F + 1% UA); and Group 7, (10% F + 2% UA). After induction of MetS (groups 3 -7), Group 3 was divided into three subgroups: 3A, no further treatment; 3B, irisin treatment; 3C, irisin treatment + exercise. Group 4, 1% UA, which was divided into three subgroups: 4A, no further treatment; 4B, irisin treatment; 4C, Irisin treatment + exercise. Group 5, 2% UA, which was divided into three subgroups: 5A, no further treatment; 5B, irisin treatment; 5C, irisin treatment + exercise. Group 6, 10% F + 1% UA, which was divided into three subgroups: 6A, no further treatment; 6B, irisin treatment; 6C, irisin treatment + exercise. Group 7, 10% F + 2% UA, which was divided into three subgroups: 7A, no further treatment; 7B, irisin treatment; 7C, irisin treatment + exercise., İrisin was administered 10 ng/kg irisin intraperitoneally on Monday, Wednesday, Friday, Sunday each week for 1 month. The exercise animals (in addition to irisin treatment) also were run on a treadmill for 45 min on Monday, Wednesday, Friday, Sunday each week for 1 month. The rats were sacrificed and samples of liver, heart, kidney, pancreas, skeletal muscles and blood were obtained. The amounts of adropin (ADR) and betatrophin in the tissue supernatant and blood were measured using an ELISA method. Immunohistochemistry was used to detect ADR and betatrophin expression in situ in tissue samples. The duration of these experiments varied from 3 and 10 weeks. The order of development of MetS was: group 7, 3 weeks; group 6, 4 weeks; group 5, 6 weeks; group 4, 7 weeks; group 3, 10 weeks. Kidney, liver, heart, pancreas and skeletal muscle tissues are sources of adropin and betatrophin. In these tissues and in the circulation, adropin was decreased significantly, while betatrophin was increased significantly due to MetS; irisin + exercise reversed this situation. We found that the best method for creating a MetS model was F + UA2 supplementation. Our method is rapid and simple. Irisin + exercise was best for preventing MetS.

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 Subfatin (Metrnl) and asprosin are associated with metabolic diseases, such as obesity and diabetes. Exercise is among the most important regulators of health in humans and has been previously demonstrated to regulate these parameters. The present study aimed to investigate the effects of different types of regular exercises on levels of subfatin, asprosin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), uric acid, and glucose. MATERIALS AND METHODS The study included 120 young and healthy males, who participated in the study voluntarily. These participants were randomly divided into four groups, such as control (C), aerobic exercise (AE), intermittent (HIIT), and resistance exercise (RE) groups. Additionally, all the groups had equal numbers of participants. First, the subjects in the exercise group were made familiar with the exercise regime for two weeks. Then, they performed regular exercises, three days a week for eight weeks. Blood samples were collected from the participants at the beginning and end of the study. Subfatin and asprosin levels were analyzed using the ELISA method. AST, ALT, uric acid, and glucose levels were analyzed using the AutoAnalyzer. RESULTS No differences were observed in pretest values between the groups (p>0.05). Assessment of intragroup changes demonstrated no significant changes in the control group. In the comparisons, statistically significant changes were recorded in the levels of subfatin, asprosin, and glucose in all exercise groups. Particularly, differences were observed in the levels of AST and uric acid in the AE and HIIT groups while differences in ALT levels were observed only in the AE group (p<0.05). CONCLUSIONS In the conclusion of the study, different types of exercises caused significant changes in subfatin and asprosin levels. Thus, these results suggested that the parameters associated with metabolic diseases could be controlled with the aid of regular exercises.

Abstract
OBJECTIVE Obesity is a serious public health problem associated with excessive food intake. Regulation of food intake in highly organized organisms is under the control of a large number of orexigenic and anorexigenic molecules. Therefore, the main purpose of this study has been to determine the relationship between obesity and some of the circulating orexigenic and anorexigenic peptides that have a role in appetite control and to determine whether the concentrations of these molecules differ according to blood groups. PATIENTS AND METHODS The study included 400 individuals of whom 100 were obese women, 100 obese men, 100 healthy men and 100 healthy women. Obese women and men were divided into 4 groups, according to their blood groups. In the control group, healthy women and healthy men were similarly divided into 4 blood groups. Each blood group within the groups, therefore, had 25 participants. RESULTS When leptin, nesfatin-1, obestatin and neuropeptide-Y, ghrelin and galanin levels of the control group and obese participants were compared, regardless of blood groups, leptin, nesfatin-1, obestatin and neuropeptide-Y were significantly higher, whereas only the ghrelin levels were significantly lower in obese patients. When the amounts of these hormones were measured according to gender, the situation was similar. When leptin, nesfatin-1, obestatin and neuropeptide-Y values of the control and obese participants' blood groups were compared with each other; these hormones were high in all blood groups; however, leptin levels in A blood group, nesfatin-1 levels in AB and O blood group, obestatin levels in AB blood group, neuropeptide-Y levels in A, B, AB blood groups were significantly higher. When the ghrelin levels of the blood groups in the control group and obese participants were compared, it was only significantly lower in the AB blood group. The ghrelin levels in the other blood groups of the obese individuals were again low, but not significantly so. When the distribution of hormones according to gender was evaluated, a situation parallel to the above results was recorded. CONCLUSIONS Leptin, nesfatin-1, obestatin and neuropeptide-Y and galanin levels of obese individuals were significantly higher than the control values, whereas the ghrelin values were significantly lower regardless of blood groups. Also, these hormones in blood partly varied with ABO blood groups. These different concentrations of hormones in ABO blood groups might be related with stimulation or suppression of appetite in human. However, further studies in other ethnic groups are needed to confirm these results.

Abstract
INTRODUCTION Kidneys are the most frequently injured organ in the genitourinary system, but there is no specific biological marker for this trauma. Renalase may be a descriptive biomarker of the pathology that causes renal ischemia, nephrotoxicity, and acute renal failure. OBJECTIVE This study investigated the role of serum and urine levels of renalase for the diagnosis of renal injury in rats with experimentally induced blunt renal trauma. STUDY DESIGN Thirty 3-month-old Sprague-Dawley adult male rats were divided into five groups (n = 6) as follows: control (Group 1), sham (Group 2), right nephrectomy (Group 3), left renal trauma (Group 4), and right nephrectomy plus left renal trauma (Group 5). Serum samples were acquired 3, 24 and 48 h post-trauma, and urine samples were acquired between 0-24 and 24-48 h post-trauma. Changes in serum and urine levels of renalase, dopamine, epinephrine, metanephrine, normetanephrine, urea, and creatinine were assessed after blunt renal trauma. RESULTS No significant changes in serum levels of these compounds were observed at 3 h post-trauma in Groups 1 and 2 or in urine collected sequentially at 0-24 and 24-48 h. By contrast, levels of renalase, dopamine, metanephrine, and normetanephrine in serum increased during hour 3 in Groups 4 and 5. Moreover, increases in urine levels of renalase, dopamine, epinephrine, metanephrine, and normetanephrine were observed at hours 0-24 in Groups 4 and 5. DISCUSSION A definitive diagnosis of traumatic renal injury in children is made with contrast-enhanced computed tomography. However, the scan results in high doses of radiation exposure to children. Here, we report for the first time that renalase levels may be useful as a biomarker for the diagnosis of renal injury due to blunt renal trauma. CONCLUSION Renalase may be a simple, effective, and noninvasive biomarker that indicates traumatic renal injury. It could be used as an adjunct for evaluation, particularly for isolated traumatic renal injury in cases where access to computed tomography is not straightforward.

Abstract
Background The aim of the study was to determine the effects of different and regularly applied exercise programs on irisin, heat shock protein 70 and some biochemical parameters. Methods 120 male university students participated in the study. Participants were divided into 4 equal groups as control (C), resistance exercise group (RE), high intensity interval (HIIT) and aerobic exercise group (AE). While the control group did not perform any exercise, the pre-determined exercise programs were applied to the other groups for 8 weeks and 3 days in a week. Blood samples were taken from all participants before and after the exercise program. Cholesterol, High-density Lipoprotein (HDL) and Low-density Lipoprotein (LDL) cholesterol, triglyceride (TG), Creatine kinase (CK), Lactate dehydrogenase (LDH), Irisin and Heat shock protein 70 (HSP70) levels were analyzed in blood samples. Results It is determined that there are significant differences in pre-posttest values of the AE group's LDH, cholesterol, HDL-cholesterol, TG and HSP 70 levels, HIIT group's CK, LDH, Cholesterol, HDL-cholesterol, TG, Irisin and HSP70 levels and RE group's CK, LDH, Cholesterol, LDL-cholesterol, TG and Irisin levels (p<0.05). Conclusions It can be said that exercise can provide improvements in lipid profile, changes in HSP70 levels may vary depending on muscle damage, the increase of irisin due to exercise.

Abstract
Abstract
Background
Childhood obesity is increasing in Turkey like all countries on the world. Sociocultural and environmental factors play very important roles in increasing childhood obesity. It is aimed to find out the prevalence of severe obesity and related factors in Turkey.
Methods
Turkey conducted Childhood Obesity Surveillance of WHO European Region in 2016. This cross-sectional epidemiologic study was representative for Turkey, the anthropometric measurements of 11523 children in 580 primary schools were taken by health care professionals, analyzed by using WHO criteria. Logistic regression model taking into account complex sample design was used to analyze to find out the factors affecting severe obesity.
Results
The prevalence of severe obesity was found as 2.8% in the children aged 6 to 9 years old. Severe obesity was found significantly 1.86 times higher in male children than female children (p = 0,002); 1.65 times higher in children whose mothers' overweighed (p = 0.01) and 3.50 much higher in children whose mothers' obese than normal weighted mothers (p < 0.001); 2.21 times higher in children whose fathers' overweighed (p < 0.001) and 2.72 times higher in children whose fathers' obese than normal weighted fathers (p < 0.001); 1.40 times higher in children whose mothers graduated from high school (p < 0.001) and 2.04 times higher whose mothers graduated from university than mothers graduated from primary school (p = 0.04); 0.58 times lower in children having families with three or more children under 18 living in the household (p = 0.03) and 1.83 times higher in children who had relatives with diabetes and high cholesterol history (p = 0.03).
Conclusions
This is the first result on severe childhood obesity in Turkey; the percentage is one of the highest rates in Europe. The significant factors affecting severe obesity were found as overweighed and obese parents, higher educated mothers, small family size and having family members with the diseases related to obesity.
Key messages
Family structure and family lifestyle are found as the main social factors related to severe obesity in Turkey. Especially, mothers need more information on the health problem related to severe childhood obesity, also healthy eating behaviors.

Abstract
Subfatin and spexin are two novel adipokines implicated in glucose homeostasis. This study was designed to investigate changes in blood subfatin and spexin levels during gestational diabetes mellitus (GDM) and childbirth, and define the mechanisms of these hormones in the physiopathology of GDM. A total of 60 pregnant women, comprising 30 diagnosed with GDM and 30 with normal gestation, were included in the study. The diagnosis of GDM was made through a 75-g oral glucose tolerance test (OGTT) administered between 24 and 28 weeks of pregnancy. The amounts of subfatin, spexin, and insulin were measured in blood samples by enzyme-linked immunosorbent assays; lipid profiles, glucose, and other biochemical parameters were measured by using an autoanalyzer. Levels of subfatin and spexin were significantly higher in blood samples drawn at baseline (before OGTT) in mothers with GDM compared to those with normal gestation. Similar observations were made in maternal and cord blood sampled at the end of pregnancy. However, at delivery, the increase in subfatin and spexin concentrations observed at baseline was abrogated in both groups of pregnant women, although levels in mothers with GDM were comparatively higher. These results show that levels of subfatin and spexin increased because of GDM and suggest that these hormones could be potential biomarkers for the diagnosis and management of GDM.

Abstract
BACKGROUND Brucella spp. are facultative intracellular pathogens that can cause chronic infections in many tissues and organs. OBJECTIVES To investigate serum dermcidin, salusin-alpha, salusin-beta and TNF-alpha levels and their correlation with each other in patients with acute brucellosis. METHODS From 50 patients hospitalized upon diagnosis of acute brucellosis, blood samples were collected and dermcidin, salusin-alpha, salusin-beta and TNF-alpha levels in serum samples were measured using an ELISA assay. The control group included 40 volunteers. RESULTS Brucellosis group had significantly lower plasma dermcidin, salusin- alpha, salusin-beta levels compared to the healthy control group (respectively p=0.008, p<0.001, p<0.001). Moreover, Brucellosis group had significantly higher plasma TNF-alpha levels comparisons with the controls (p=0.002). In the examination of the correlation between TNF-alpha and dermcidin, salusin-alpha and salusin-beta in the brucellosis group, only a negative correlation was found between salusin-beta and TNF-alpha. In the control group, there was a positive and statistically significant correlation between salusin-beta and TNF-alpha. CONCLUSION Dermcidin, salusin-alpha, and particularly salusin-beta levels are important in Brucella pathogenesis. The paradoxical correlation between TNF-alpha and salusin-beta in patients with brucellosis and control group is remarkable. However, there is a need for extensive studies conducted with more patients to further elucidate this topic.

Abstract
BACKGROUND Chemerin and dermcidin, which have antimicrobial properties, are molecules that are also related to insulin resistance and inflammation. RESEARCH AIMS The aims were to determine the amounts of chemerin and dermcidin in the milk and blood of mothers with gestational diabetes, and to compare the amounts of chemerin and dermcidin in the milk and blood of mothers with and without diabetes. METHODS This was a two-group nonrandomized longitudinal study with a convenience sampling of mothers without gestational diabetes (n = 27) and mothers with gestational diabetes (n = 26). Human milk and blood samples were obtained from these mothers during colostrum, transitional, and mature milk periods. The amount of chemerin and dermcidin in these samples was measured by enzyme-linked immunosorbent assay. RESULTS The presence of chemerin and dermcidin was first detected in human milk. The amounts of chemerin and dermcidin in the blood of all the mothers were greater in the colostrum period and lowest in the mature period. The amount of chemerin and dermcidin in the milk of all the mothers was greater than that in the blood. The amounts of chemerin and dermcidin were significantly increased in both blood and human milk within the gestational age samples. CONCLUSIONS Chemerin and dermcidin may contribute to the protection of infants from infections during infancy. Increased amounts of these molecules found within the gestational diabetes group may also prevent adverse maternal and fetal outcomes.

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
Aim The aim of this study was to investigate ELABELA (ELA) expression in benign and malignant renal tissues and expression differences in different nuclear grades of clear cell carcinomas. Materials and Methods Patients that underwent surgery due to renal masses between the years of 2007 and 2017 were used. Control renal tissues (n = 23), papillary RCC (n = 23), clear cell RCC (CcRCC) [Fuhrman Grade1 (n = 23), Fuhrman Grade2 (n = 23), Fuhrman Grade3 (n = 23), Fuhrman Grade4 (n = 23)], and chromophobe RCC (n = 23) were included to the study. The Independent samples t-test was used for 2-point intergroup assessments and the one-way analysis of variance and posthoctukey test was used for the others. Values of P < 0.05 were considered statistically significant. Results ELA immunoreactivity was observed in proximal and distal tubules in the kidney, but not in glomeruli in control tissues. When compared with control kidney tissue, a statistically significant increase was observed in ELA immunoreactivity in renal oncocytoma. In the chromophobe RCC, ELA immunoreactivity was significantly lower than control kidney tissue, whereas papillary RCC did not show ELA immunoreactivity. However, compared with control kidney tissue, ELA immunoreactivity was not observed in Fuhrman Grade 1 and Grade 2 CcRCC. Also, there was a significant decrease at Fuhrman Grade 3 and Grade 4 CcRCC compared with control kidney tissues. In the statistical analysis of ELA immunoreactivity among the Fuhrman nuclear grades of CcRCCs, The ELA immunoreactivity was higher at Grade 4 CcRCC than Grade 1, Grade 2, and Grade 3. Conclusion ELA is a usefull molecule to differentiate benign and malign renal tumors. But further broad and comprehensive studies are needed to investigate cellular and molecular mechanisms of ELAs on malign transformation.

Abstract
Obesity and hyperandrogenemia are known to have adverse effects on both developing follicle and endometrium receptivity in polycystic ovarian syndrome (PCOS). Insulin resistance also contributes to this dilemma as a cause or a consequence and leads to worsening of the clinical picture. The difficulty in obtaining pregnancy despite the presence of a large number of oocyte has concentrated our attention on oocyte quality and development. However, the occurence of subfertility has also caused us to investigate the presence of different etiologic agents in non-obese PCOS women with normal androgen and insulin levels. In this context peptides have become the most accused and investigated molecules in cases of impaired fertility due to PCOS. Most of the studies investigating the relationship between PCOS and peptide did not support each other. The difficulties in measuring peptide levels as well as the individual variations in peptide synthesis and release are possible causes of this incongruity. For all these reasons, the incorporation of studies investigating the relationship between PCOS, peptide and subfertility in an article has become critical to pioneering future work. Understanding the association between peptides and subfertility will help us to understand the effects of peptides on failed fertility in PCOS. Moreover, updating our knowledge about peptides may allow us designing new drugs to to treat subfertility in PCOS. This review provides a general summary of the mechanisms of action of neuroendocrine peptides in regulating reproductive events. Since it is not usual to discuss all peptides in this context, only the effects of key central and peripheral peptides on fertility in PCOS have been extensively addressed.

Abstract
Objective: The incidence of thyroid cancer has been continuously increasing. The main objective of this study was to investigate irisin expression in various thyroid pathologies and to compare these expression patterns with irisin expression in healthy thyroid tissues. Methods: The study groups consisted of 20 cases each of control thyroid tissue, Hashimoto’s thyroiditis, thyroid papillary carcinoma, oncocytic papillary carcinoma, follicular thyroid carcinoma, oncocytic follicular thyroid carcinoma, medullary thyroid carcinoma, anaplastic thyroid carcinoma. Irisin expression was evaluated using immunohistochemistry. Irisin levels in thyroid tissue supernatants were measured using ELISA. Results: Patients with HT showed increased irisin expression compared with controls (p<0.05). In addition, mild immunoreactivity was observed in the thyroid tissues of patients with papillary carcinoma while significantly increased irisin immunoreactivity was observed tissues of patients with oncocytic papillary carcinoma (p<0.05). There was no difference in irisin immunoreactivity in thyroid tissues between patients with follicular carcinoma and controls. However, irisin immunoreactivity was higher in tissues of patients with oncocytic follicular carcinoma than in tissues of patients with follicular carcinoma (p<0.05). No irisin immunoreactivity was observed in tissues of patients with medullary carcinoma, a malignant tumor the thyroid; however, irisin expression was significantly increased in tissues of patients with anaplastic carcinoma compared with that in tissues of controls (p<0.05). Furthermore, in all thyroid tissues with irisin expression, irisin immunoreactivity was observed in follicular cells, indicating that irisin is produced by these cells. Conclusion: Irisin is a novel potential immunohistochemical marker for differentiating oncocytic variants of papillary and FTCs from papillary and follicular thyroid cancers.

Abstract
We investigated the expression of irisin in renal cancers using immunocytochemistry. Irisin has been reported to exhibit anticancer properties. The study groups consisted of 22 cases each of control renal tissue, oncocytoma, chromophobe renal cell carcinoma (RCC), clear cell RCC (Fuhrman nuclear grades 1, 2, 3 and 4) and papillary RCC. We evaluated 10 slides for each of 176 cases. Slides were immunostained for irisin and histoscores were calculated for the prevalence and strength of immunostaining. Fuhrman nuclear grade 1, 2, 3 clear cell RCC and papillary RCC exhibited no irisin immunoreactivity. Irisin immunoreactivity was observed in some Fuhrman nuclear grade 4 RCCs. We found a significant decrease in irisin staining in chromophobe RCC compared to the control. Immunoreactivity in the oncocytoma tissue was comparable to the control group. Irisin immunoreactivity in chromophobe RCC decreased and no immunoreactivity was observed in Fuhrman nuclear grade 1, 2, 3 clear cell RCC and papillary RCC. Immunistochemical screening of irisin in renal oncocytomas and renal cancers may be useful for differential diagnosis.

Abstract
Purpose Acute myocardial infarction (AMI) is the most common cause of death in the world. Comprehensive risk assessment of patients presenting with chest pain and eliminating undesirable results should decrease morbidity and mortality rates, increase the quality of life of patients, and decrease health expenditure in many countries. In this study, the advantages and disadvantages of the enzymatic and nonenzymatic biomarkers used in the diagnosis of patients with AMI are given in historical sequence, and some candidate biomarkers – hFABP, GPBB, S100, PAPP-A, RP, TNF, IL6, IL18, CD40 ligand, MPO, MMP9, cell-adhesion molecules, oxidized LDL, glutathione, homocysteine, fibrinogen, and D-dimer procalcitonin – with a possible role in the diagnosis of AMI are discussed. Methods The present study was carried out using meta-analyses, reviews of clinical trials, evidence-based medicine, and guidelines indexed in PubMed and Web of Science. Results These numerous AMI biomarkers guide clinical applications (diagnostic methods, risk stratification, and treatment). Today, however, TnI remains the gold standard for the diagnosis of AMI. Details in the text will be given of many biomarkers for the diagnosis of AMI. Conclusion We evaluated the advantages and disadvantages of routine enzymatic and nonenzymatic biomarkers and the literature evidence of other candidate biomarkers in the diagnosis of AMI, and discuss challenges and constraints that limit translational use from bench to bedside.

Abstract
BACKGROUND Failure to respond adequately to standard protocols and to recruit adequate follicles is called 'poor ovarian response'. The relationships between metabolic alterations and NUCB2/Nesfatin-1 levels were explored in patients with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization/intracytoplasmic sperm injection. METHODS This case-control study involved 20 infertile women with PCOS and 20 control women diagnosed as poor ovarian responders stimulated with a GnRH antagonist. Blood samples were taken during ovum pick-up and follicular fluids (FF) were obtained from a dominant follicle from the subjects. Samples were analyzed by using ELISA. Statistical analysis was performed with SPSS version 20. Data are expressed as means ± standard deviation (SD). RESULTS Blood NUCB2/Nesfatin-1 levels in PCOS were significantly lower (p= 0.011) while the NUCB2/Nesfatin-1 levels of FF in poor ovarian response (POR) were higher, but not statistically significant. Insulin, total testosterone, fasting glucose, homeostasis model assessment, and insulin resistance index in women with POR decreased when compared with PCOS. Blood NUCB2/Nesfatin-1 levels were significantly higher than FF NUCB2/Nesfatin-1 levels in both groups (p<0.001). Moreover, a positive correlation was detected between blood NUCB2/Nesfatin-1 and testosterone (p=0.602, r=0.304), HOMA-IR (p=0.252, r=0.384), BMI (p=0.880, r= 0.44) in PCOS, but it was not significant. CONCLUSION NUCB2/Nesfatin-1 levels might be important in follicular growth in PCOS subjects undergoing IVF/ICSI with an antagonist protocol and NUCB2/Nesfatin-1 level could reliably help to predict poor ovarian response.

Abstract
This study was planned to test whether follicular fluid (FF) levels of patatin-like phospholipase domain containing 3-gene (PNPLA3:adiponutrin), preptin, kisspeptin, and amylin change in polycystic ovarian syndrome (PCOS). A total of 40 infertile volunteers undergoing IVF/ICSI were included in the study. They were divided into two groups as PCOS (n=20) and control group without PCOS (n=20). The controls were recruited from subjects with a poor ovarian response. The PCOS and control participants were matched according to their body mass index (BMI). Each group of participants underwent ovarian stimulation with GnRH antagonist protocol. Blood and FF samples of one dominant follicle were obtained from each subject during the oocyte pick-up. FF and serum levels of PNPLA3, preptin, kisspeptin and amylin were measured through ELISA. Amylin and adiponutrin median values were not different according to study groups (p>0.05). FF-preptin median values in the control group were similar to the serum preptin values of control and PCOS groups (Z=0.970, p=1.000 and Z=2.631, p=0.051, respectively). Medians of the serum preptin in control and PCOS groups were the same (Z=1.649; p=0.595). FF-preptin median values of PCOS group were significantly lower than the preptin median values of the control group. Serum preptin levels were positively correlated with HOMA-IR, but not with pregnancy rates and the number of retrieved oocytes. Serum kisspeptin levels were negatively correlated with the number of retrieved oocytes and pregnancy rates. While amylin and adiponutrin have no role in the folliculogenesis, kisspeptin and preptin work together for regulating follicle developmental capacity in PCOS.

Abstract
INTRODUCTION Delay in the diagnosis of ovarian torsion leads to serious histopathological changes and many problems, including infertility. Various agents have been investigated to minimize detorsion-associated potential injury. This study was performed to study the effects of carnosine and vitamin E on tissue and serum expression of Nucleobindin 2 (NUCB2)/nesfatin-1, ghrelin, adropin, and irisin to determine whether they have protective effects in cases of ovarian torsion. MATERIAL AND METHOD Seventy-eight rats were allocated evenly into 13 groups. All rats, excluding those in the control and sham groups and Groups (G) III, IV, and V, were subjected to ovarian torsion for 12 hours. The groups were designated as follows: G-I (control), G-II (sham), G-III (vitamin E), G-IV (carnosine), G-V (carnosine + vitamin E), G-VI (torsion), G-VII (torsion + detorsion), G-VIII (torsion + vitamin E), G-IX (torsion + carnosine), G-X (torsion + carnosine + vitamin E), G-XI (torsion + detorsion + vitamin E), G-XII (torsion + detorsion + carnosine), and G-XIII (torsion + detorsion + carnosine + vitamin E). Serum levels of NUCB2/nesfatin-1, ghrelin, adropin, and irisin were measured by ELISA. Immunohistochemical methods were used to measure the expression of these hormones in ovarian tissue. RESULTS The levels of NUCB2/nesfatin-1 immunoreactivity were increased in G-VII, G-XI, and G-XII (p<0.05). The immunoreactivity of ghrelin was significantly decreased in G-VI, G-IX, G-XI, and G-XII. However, adropin immunoreactivity did not differ significantly between the groups (p>0.05). The level of irisin immunoreactivity was decreased in G-VI, G-VII, and G-VIII (p<0.05). The serum levels of NUCB2/nesfatin-1, ghrelin, adropin, and irisin paralleled the tissue immunohistochemical results. CONCLUSION Carnosine and vitamin E protected the ovaries from ischemia-reperfusion injury in ovarian torsion. These antioxidants, especially carnosine, may be useful for the treatment of ovarian torsion.

Abstract
Aim Insufficient oxygen supply to organs and tissues due to reduced arterial or venous blood flow results in ischaemia, during which, although ATP production stops, AMP and adenosine continue to be produced from ATP. The fate of irisin, which causes the production of heat instead of ATP during ischaemia, is unknown. Iloprost and sildenafil are two pharmaceutical agents that mediate the resumption of reperfusion (blood supply) via vasodilatation during ischaemic conditions. Our study aimed to explore the effects of iloprost and sildenafil on irisin levels in the heart, liver and kidney tissues and whether these pharmaceutical agents had any impact on serum irisin and nitric oxide levels in rats with induced experimental myocardial ischaemia. Methods The study included adult male Sprague-Dawley rats aged 10 months and weighing between 250 and 280 g. The animals were randomly allocated to eight groups, with five rats in each group. The groups were: sham (control), iloprost (ILO), sildenafil (SIL), ILO + SIL, myocardial ischaemia (MI), MI + ILO, MI + SIL and MI + ILO + SIL. The treatment protocols were implemented before inducing ischaemia, which was done by occluding the left coronary artery with a plastic ligature for 30 minutes. Following the reperfusion procedure, all rats were sacrificed after 24 hours, and their heart, liver and kidney tissues and blood samples were collected for analyses. An immunohistochemical method was used to measure the change in irisin levels, the ELISA method to quantify blood irisin levels, and Griess’ assay to determine nitric oxide (NO) levels in the serum and tissue. Myocardial ischaemia was confirmed based on the results of Masson’s trichrome staining, as well as levels of troponin and creatine kinase MB. Results Irisin levels in biological tissue and serum dropped statistically significantly in the ischaemic group (MI), but were restored with ILO and SIL administration. Individual SIL administration was more potently restorative than individual ILO administration or the combined administration of the two agents. NO level, on the other hand, showed the opposite tendency, reaching the highest level in the MI group, and falling with the use of pharmaceutical agents. Conclusions Individual or combined administration of ILO and SIL reduced myocardial ischaemia and NO levels, and increased irisin levels. Elevated levels of irisin obtained by drug administration could possibly contribute to accelerated wound recovery by local heat production. Sildenafil was more effective than iloprost in eliminating ischaemia and may be the first choice in offsetting the effects of ischaemia in the future.

Abstract
Testicular torsion (TT) is a common urological problem in the field of pediatric surgery. The degree and duration of torsion determines the degree of testicular damage; however, its effects on the expression of octanoylated ghrelin and nucleobindin 2 (NUCB2) /nesfatin-1 synthetized from testicular tissue remain unclear. We explored the effects of experimentally induced unilateral TT on serum and contralateral testicular tissue ghrelin and NUCB2/nesfatin-1 levels, and determined whether N-acetyl cysteine (NAS) treatment had any effects on their expression. A total of 42 Wistar Albino strain rats were divided into 7 groups: Group (G) I control, GII sham, GIII 12-hour torsion, GIV 12-hour torsion + detorsion + 100 mg/kg NAS, GV 24-hour torsion, GVI 24-hour torsion + detorsion + 100 mg/kg NAS, and GVII 100 mg/kg NAS. Octanoylated ghrelin and NUCB2/nesfatin-1 concentrations were evaluated in serum using the ELISA method and in testicular tissue with immunohistochemical methods. Immunoreactivity of octanoylated ghrelin significantly increased in GI compared to GIII, GV, and GVI (p<0.05). NUCB2/nesfatin-1 immunoreactivity increased in GV and GVIII relative to GI (p<0.05). In the 12-hour torsion group, a significant decrease in octanoylated ghrelin levels with NAS treatment was observed; however, in the 24-hour torsion group, a significant decrease was not observed. In the 12-hour torsion + NAS treatment group, a significant change was not observed in NUCB2/nesfatin-1 expression. Following 24-hour torsion, an increase in NUCB2/nesfatin-1 levels was observed, and NAS treatment did not reverse this increase. It was determined that increases in the expression of octanoylated ghrelin and NUCB2/nesfatin-1, the latter of which was a result of TT, reflect damage in this tissue. Importantly, NAS treatment could prevent this damage. Thus, there may be a clinical application for the combined use of NAS and octanoylated ghrelin in preventing TT-related infertility.

Abstract
Objective The aim of this study was to assess the changes of follicular fluid (FF) and serum levels of cerebellin precursor protein 1 (cbln1) and betatrophin in patients with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) with a gonadotropin-releasing hormone (GnRH) antagonist protocol. Methods Twenty infertile women with PCOS and 20 control women diagnosed as poor responders undergoing ovarian stimulation with a GnRH antagonist were included. Blood samples were obtained during ovum pick-up. Follicular fluid from a dominant follicle was collected from the subjects. Using enzyme-linked immunosorbent assays, FF and serum levels of cbln1 and betatrophin were measured in both groups of participants. Metabolic and hormonal parameters were also determined and correlated with each other. Results Both groups of women had similar serum and FF betatrophin levels (55.0±8.9 ng/mL vs. 53.1±10.3 ng/mL, p=0.11). The serum and FF betatrophin levels of poor responders were found to be similar (49.9±5.9 ng/mL vs. 48.9±10.7 ng/mL, p=0.22). Conversely, the FF cbln1 levels of PCOS women were found to be significantly higher than the serum cbln1 levels (589.1±147.6 ng/L vs. 531.7±74.3 ng/L, p<0.02). The FF cbln1 levels of control participants without PCOS were significantly higher than their serum cbln1 levels (599.3±211.5 ng/L vs. 525.3±87.0 ng/L, p=0.01). Positive correlations were detected among body mass index, insulin resistance, serum insulin, total testosterone, and betatrophin levels in the PCOS group. Conclusion Follicular fluid betatrophin and cbln1 concentrations may play a pivotal role on follicular growth in PCOS subjects undergoing IVF/ICSI with an antagonist protocol.

Abstract
To determine expression pattern of irisin in tissues obtained from human ovarian cancer, breast cancer, and cervix cancer. Tissue samples obtained from subjects with breast cancer, ovarian cancer cervix cancer, simple endometrial hyperplasia, complex atypical endometrial hyperplasia. At least five sections from each subject were immunohistochemically stained with irisin antibody, and H-score method was used to evaluate irisin intensity. Tissues obtained from healthy breast tissues, proliferative phase endometrium adenomyosis and benign ovarian tumors were accepted as control. Irisin activity was not detected in control breast tissues significantly increased irisin staining was detected in invasive lobular, intraductal papillary, invasive ductal, invasive papillary, and mucinous carcinomas compared to control tissues. Also, significantly increased irisin immunoreactivity was detected in both ovarian endometriosis and mucinous carcinomas compared to benign tumors. However irisin staining was not observed at the papillary carcinoma of the ovary while sections obtained from simple and complex atypical endometrial hyperplasia, and cervix carcinoma demonstrated irisin immunoreactivity. Increased irisin immunoreactivity in tissues obtained from breast, ovary, cervix carcinomas, and endometrial hyperplasia suggest critical role of this peptide during carcinogenesis.

Abstract
A 112-amino-acid protein irisin (IRI) is widely expressed in many organs, but we currently do not know whether appendix tissue and blood cells express it. If appendix tissue and neutrophil cells express IRI, measuring its concentration in biological fluids might be helpful in the diagnosis of acute appendicitis (AA), since neutrophil cells are the currently gold-standard laboratory parameters for the diagnosis of AA. Therefore, the purpose of this study was to investigate the suitability of enzyme-linked immunosorbent assay-based measurements of the proposed myokine IRI for the discrimination of patients with AA from those with acute abdominal pain (AP) and healthy controls. Moreover, immunoreactivity to IRI was investigated in appendix tissues and blood cells. Samples were collected on admission (T1), 24 hours (T2), and 72 hours (T3) postoperatively from patients with suspected AA and from patients with AP corresponding to T1–T3, whereas control subject blood was once corresponding to T1. IRI was measured in serum, saliva, and urine by using enzyme-linked immunosorbent assay, whereas in appendix tissue and blood cells, IRI was detected by immunohistohcemistry. Appendix tissue and blood cells (except for erythrocytes) are new sources of IRI. Basal saliva, urine, and serum levels were higher in children with AA compared with postoperative levels (T2) that start to decline after surgery. This is in line with the finding that IRI levels are higher in children with AA when compared with those with AP or control subject levels, most likely due to a large infiltration of neutrophil cells in AA that release its IRI into body fluids. Measurement of IRI in children with AA parallels the increase or decrease in the neutrophil count. This new finding shows that the measurement of IRI and neutrophil count can together improve the diagnosis of AA, and it can distinguish it from AP. IRI can be a candidate marker for the diagnosis of AA and offers an additional parameter to neutrophil count. The promising receiving operating curve results indicate the following sensitivities and specificities, respectively, for IRI: serum 90% and 55%, saliva 90% and 60%, and urine 90% and 50%. Serum neutrophil count gave a sensitivity of 90% and a specificity of 90%. This promising result now needs to be confirmed in a larger group of patients.

Abstract
Aim Enzyme-positive acute coronary syndrome (EPACS) can cause injury to or death of the heart muscle owing to prolonged ischaemia. Recent research has indicated that in addition to liver and brain cells, cardiomyocytes also produce adropin. We hypothesised that adropin is released into the bloodstream during myocardial injury caused by acute coronary syndrome (ACS), so serum and saliva levels rise as the myocytes die. Therefore, it could be useful to investigate how ACS affects the timing and significance of adropin release in human subjects Methods Samples were taken over three days after admission, from 22 EPACS patients and 24 age- and gendermatched controls. The three major salivary glands (submandibular, sublingual and parotid) were immunohistochemically screened for adropin production, and serum and saliva adropin levels were measured by an enzyme-linked immunosorbent assay (ELISA). Salivary gland cells produce and secrete adropin locally. Results Serum adropin, troponin I, CK and CK-MB concentrations in the EPACS group became gradually higher than those in the control group up to six hours (p < 0.05), and troponin I continued to rise up to 12 hours after EPACS. The same relative increase in adropin level was observed in the saliva. Troponin I, CK and CK-MB levels started to decrease after 12 hours, while saliva and serum adropin levels started to decrease at six hours after EPACS. In samples taken four hours after EPACS, when the serum adropin value averaged 4.43 ng/ml, the receiver operating characteristic curve showed that the serum adropin concentration indicated EPACS with 91.7% sensitivity and 50% specificity, while when the cut-off adropin value in saliva was 4.12 ng/ml, the saliva adropin concentration indicated EPACS with 91.7% sensitivity and 57% specificity. Conclusion In addition to cardiac troponin and CK-MB assays, measurement of adropin level in saliva and serum samples is a potential marker for diagnosing EPACS.

Abstract
OBJECTIVE We examined the follicular fluid (FF) and serum levels of irisin in high and poor responders undergoing IVF/ICSI to test whether irisin has a role in the metabolic regulation of energy homeostasis in growing follicle. PATIENTS AND METHODS Twenty infertile women with PCOS and 20 poor responder participants undergoing controlled ovarian stimulation (COS) with GnRH antagonist protocol for IVF/ICSI treatment were allocated. Blood was obtained at the time of oocyte retrieval. The follicular fluid content of mature follicles was collected from both high and poor responder women. Irisin levels were measured by using EIA. RESULTS There was no significant difference between serum and FF-irisin levels in women with PCOS. (11.18 ± 5.14 µg/mL vs. 11.06 ± 4.93 µg/mL, p < 0.96). In contrast, serum levels of irisin in poor responders were significantly higher than in the FF-irisin levels (13.13 ± 4.27 µg/mL vs. 10.09 ± 4.14 µg/mL, p < 0.01). FF-irisin levels of PCOS subjects were positively and significantly correlated with serum levels of irisin (r: 0.81, p < 0.00). Serum irisin was positively associated with serum levels of total testosterone but was negatively associated with HOMA-IR in the overall patient population. FF-irisin levels were also noted to be negatively correlated with HOMA-IR. Although there is no correlation between serum irisin and AMH levels, FF irisin levels were negatively correlated with serum AMH levels in PCOS subjects. Contrary to PCOS group there were no significant correlation between serum and FF-irisin levels in poor responder group (r: 0.21; p < 0.35). CONCLUSIONS The present study is the first attempt to explore the role of irisin in oocyte development by measuring FF and serum levels of this molecules in patients with poor and high responders undergoing IVF/ICSI.

Abstract
Transient glucose intolerance (TGI) is an important cause of WHO G-ORS (Glucose-Oral Rehydration Solution) treatment failure and hospitalization in dehydrated children during acute diarrhoea. This retrospective case-control study was designed to determine some risk and predictive factors for developing TGI among moderately dehydrated patients with acute diarrhoea while under G-ORS therapy. Among moderately dehydrated patients, files of 22 patients with TGI and 66 other dehydrated patients without intolerance were reviewed. Patients with TGI were younger (9.7+/-10.5 mo and 11.6+/-7.8 mo, respectively, p < 0.05), the median age being 6 mo in the TGI group and 10 mo in non-TGI group. There was no difference between groups for sex, admission season, history of fever or vomiting, frequency of vomiting, presence of blood, mucous or leukocyte in stool, presence of associated disease and duration of diarrhoea on admission. The admission haemoglobin, white blood cell, blood pH, sodium and potassium levels were similar in both groups. The mean serum chloride level (116.8+/-6.9, 109.6+/-7.9 mEq/l, respectively, p<0.05) was higher in the TGI group and the bicarbonate level was lower (12.9+/-3.8, 15.3+/-6.0, respectively, p < 0.05). Stool frequency was also higher in patients with TGI (11.2+/-5.3/24 h, 5.9+/-4.4/24 h, respectively, p < 0.05). No difference was found between the nutritional status of children in both groups. More children were breastfed in the group without TGI (34/56, 61%, 6/18, 33% respectively, p=0.079, OR=0.32, 95% CI [0.09-1.11]). It was concluded that patients with TGI are younger and have high stool frequency. Although statistical significance could not be shown, breastfeeding seems to protect children from TGI, as it protects from diarrhoea.

Abstract
We studied a young man with spastic right hemiparesis, in whom supramaximal stimulation of the left posterior tibial nerve produced toe movements of the both feet and associated late responses in the flexor hallucis brevis muscle bilaterally. These findings indicate that, in this patient, there are central connections between peripheral afferents and contralateral alpha-motor neurons. It may be that such connections are normally present but that they are too weak in normal subjects to produce firing of the alpha-motor neurons by themselves. If so, the loss of cortical inhibition in our patient may have allowed these connections to produce movement.

Abstract
A patient with mirror movements associated with cervical meningocele has been presented in this report. The MRI showed normal cerebrum and cervical meningocele, and an anomaly at the posterior to the cervical spinal cord-medulla junction. Unilateral transcranial magnetic stimulation evoked bilateral responses at similar latencies on the thenar muscles which are quite different from those observed in normal subjects. This case adds another etiological cause to the mirror movements.

Abstract
We report on a patient with traumatic dissection limited to the basilar artery causing a locked-in syndrome. Magnetic resonance imaging (MRI) showed infarction of the basis pontis and a high signal intensity ring surrounding the central lumen of the basilar artery. Vertebral angiography revealed a double lumen within the basilar artery, consistent with a dissection. MRI and angiography are complementary to each other, and we consider both to be necessary for accurate diagnosis. Because MRI is less invasive than angiography, MR examinations should be performed before angiography for screening.

Abstract
Chronic encapsulated intracerebral hematoma, which is usually seen in young, normotensive patients, is rare, but has been reported with increasing frequency in recent years. In this report, we have presented a case of encapsulated intracerebral hematoma mimicking intratumoural bleeding with its whole natural radiological progression. A 55 year-old man developed a progressive neurological deficit one month after hospitalisation due to spontaneous intracerebral hemorrhage. Cranial CT and MR demonstrated a ring-shaped hemorrhagic lesion with mass effect and perifocal edema. After 15 months, there was marked improvement in clinical findings, and imaging techniques showed marked resorption of the mass. Radiological findings of spontaneous resolution of the encapsulated intracerebral hematoma are described for the first time in the reported case. Encapsulated intracerebral hematoma can present much like a brain tumour and should be considered in the differential diagnosis of other hemorrhagic space-occupying lesions.

Abstract
We report a 20 year-old, 28 week-pregnant woman, who developed superior sagittal sinus thrombosis, associated with a decreased free protein S level. Her father, who had been a stroke victim, had also significantly lower level of protein S. In very rare cases, a congenital or acquired protein S deficiency leads to cerebral venous thrombosis. The detection of such abnormalities has major practical consequences for the long-term management of patients to prevent further thrombotic episodes.

Abstract
We report an autopsy-proven case of SSPE in which the course was rapidly progressive, leading to death in 2 months. The patient was admitted for investigation of visual symptoms. His examination revealed complete right homonymous hemianopia and myoclonic jerks in the right half of the body. EEG showed high voltage periodic slow-wave discharges that were often associated with jerks. Measles antibody was positive in serum and CSF. MRI showed hyperintensity in the white matter of the occipital poles. The patient became completely blind and had jerks in all four limbs. His condition continued to deteriorate and within 3 weeks he reached a state of deep coma. The myoclonic jerks became less marked and gradually completely ceased. The EEG showed diffuse slow activity without periodic complexes. The patient died approximately 2 months from onset of disease. Brain autopsy revealed severe neuronal loss with abundant inclusion bodies in the remaining neuronal and oligodendroglial nuclei, which was compatible with SSPE.

Abstract
We report a 20-year-old male with epilepsy, mild mental retardation, growth asymmetry, and MRI and SPECT features of unilateral subcortical ectopic cortex. The neurological examination showed mild growth asymmetry, hemiparesis and hemihypoesthesia and pyramidal signs on the left side. EEG showed focal abnormality in the right frontotemporal region. MRI revealed pachygyria and severe heterotopia associated with some abnormalities of ventricles and cerebellum on the right. Cortical responses were absent on stimulation of the left median and tibial nerves. Central motor conduction time from cortex to left upper extremity was prolonged in magnetic stimulation test. SPECT using 99 mTc-HMPAO revealed increased perfusion of the right subcortical region as compared with those of overlying cortical mantle and opposite hemisphere. To our knowledge, there has been no report documenting such a large and extensive subcortical ectopic cortex which appears as a mass distorting and shifting the middle structure in an adult, such as in our case.

Abstract
We report a case of Tolosa-Hunt syndrome (THS) in which the lesion has been demonstrated by magnetic resonance imaging (MRI), computed tomography (CT), and angiography. A healthy 23-year-old man developed an acute painful ophthalmoplegia on the right side. CT and MRI scans revealed asymmetric enlargement of the right cavernous sinus with contrast enhancement extending down to the region of trigeminal ganglion. MRI further delineated the detailed anatomical structures of the region and excluded any infiltration of the surrounding tissues by a mass lesion. Cerebral angiography showed a significant decrease in the calibration of petrous segment and a mild decrease in the calibration of cavernous segment of the ipsilateral internal carotid artery. The patient was treated with oral prednisone, 100 mg daily. Neurological findings totally subsided after 2 weeks on corticosteroid and MRI showed resolution of the lesion in the cavernous sinus. The patient was symptom-free for 6 months after discharge. Our findings have suggested that MRI is the most valuable imaging technique for demonstration and follow-up of lesions in the cavernous sinus that are directly responsible for the symptoms of THS and the lesions can be more extensive than was currently believed.

Abstract
Deficiency or excess of thyroid hormones is associated with central nervous system (CNS) disturbances. Although the CNS involvement either in hypothyroidism or in hyperthyroidism have previously been shown on the basis of visual, auditory and somatosensory evoked potentials studies, less is known about the function of central motor pathways in both disorders. We studied the motor evoked potentials (MEPs) following the magnetic stimulation of the motor cortex and spinal roots in 20 patients with hypothyroidism and in 19 patients with hyperthyroidism both before treatment and after they became euthyroid and compared with findings in 20 age-, sex- and height-matched control subjects. Disease duration (expressed as time from diagnosis of diseases to the time of neurological testing) is less than one month in both disorders. Central motor conduction time (CMCT) was determined as the differences between MEPs latencies after cortical and spinal stimulation. The mean CMCTs before treatment in hypothyroid patients (8.31 +/- 1.52 msec.) and in hyperthyroid patients (7.92 +/- 1.06 msec.) were significantly prolonged as compared to those in normal controls (6.82 +/- 0.83 msec. p = 0.002 and p = 0.004, respectively). Four of the 20 (20.0%) hypothyroid patients and 2 of 19 (10.5%) hyperthyroid patients had abnormal CMCT (values exceeding mean +2.5 SD of normal control). The mean CMCT values in both groups were not significantly decreased after euthyroidism was achieved, although a tendency of the decrease in CMCT was observed. Improvement of CMCT abnormalities was observed in 1 of 4 hypothyroid patients and in one of 2 patients with hyperthyroidism, who had CMCT abnormalities before treatments, after they became euthyroid. No correlation was found between CMCT and free T3, free T4, or TSH levels as well as the onset age, the severity of the diseases or the disease duration in both disorders. We conclude that abnormal CMCT could be documented in few patients in both disorders. However, these alterations could not be improved completely after restoration of euthyrodism. Thus, it remains to be determined if long-term treatment would completely improve CMCT abnormalities in both disorders. Since abnormal CMCT values in both disorders were observed only in few patients, our results also suggest that CMCT measurement does not have, at present time, a clinical usefulness to assess the peripheral action of thyroid hormones. Thus, the data obtained need a more extensive evaluation.

Abstract
Although functional alterations in the central nervous system (CNS) and peripheral nerves are well documented in overt hypothyroidism, little is known about alterations of CNS in acute hypothyroidism. Sixteen patients with differentiated thyroid carcinoma were studied when prepared for radioiodine scanning after stopping levothyroxine (L-T4) therapy for 6 weeks to determine whether acute hypothyroidism leads to alteration in somatosensory evoked potentials (SSEPs). Repeat SSEPs were performed on the same patients at 6 months following L-T4 therapy when patients were euthyroid. Neurophysiological findings were compared with a group of 20 normal controls with no history of thyroid disease. Peripheral and central conduction in the median and tibial nerve stimulated SSEPs studied. A significant prolongation of central conduction time in SSEPs was found in patients with acute hypothyroidism when compared to those in control subjects. Abnormal latencies were not correlated with thyroid hormone levels. These neurophysiologic abnormalities were completely restored to normal at 6 months after L-T4 therapy. We conclude that acute hypothyroidism leads to reversible alterations in CNS as determined by SSEP recordings. Our results also suggest that SSEPs could be useful tests to monitor functional alteration of the CNS in acute hypothyroidism.
