Abstract
The study is aimed at studying the association between the levels of serum adiponectin (ADPN), high-sensitivity C-reactive protein (hs-CRP), and soluble intercellular adhesion molecule-1 (sICAM-1) and hypertensive cerebrovascular complications. 50 patients with hypertensive cerebrovascular disease treated in Gansu Provincial Hospital from December 2016 to December 2018 were selected as the experimental group, and 50 normal people who underwent physical examination were selected as the control group. The blood pressure, heart rate, and the complications were recorded, and the serum blood lipid indexes were detected. Moreover, the content of serum ADPN, hs-CRP, and sICAM-1; the neurological indexes; brain-derived neurotrophic factor (BNDF); and neurone-specific enolase (NSE) were also determined using ELISA. The content of aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and serum creatinine (SCR) in the experimental group was significantly higher than that in control group (p < 0.05); the incidence of cerebrovascular complications, systolic blood pressure, diastolic blood pressure, and heart rate increased (p < 0.05); the content of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), hs-CRP, and sICAM-1 obviously rose (p < 0.05); and the content of ADPN and HDL obviously declined (p < 0.05). Besides, the experimental group had evidently lower systolic blood flow velocity (Vs), diastolic blood flow velocity (Vd), and mean blood flow velocity (Vm) and evidently higher pulsatility index (PI) (p < 0.05). The levels of S100 and NSE in the experimental group increased significantly, and the level of BNDF decreased significantly (p < 0.05). In patients with hypertensive cerebrovascular disease, the level of ADPN declines; the levels of hs-CRP and sICAM-1 rise; the incidence rate of cerebrovascular complications is elevated; and there are changes in the blood lipid, cerebrovascular hemodynamic, and neurological indexes, thereby further promoting the occurrence and development of hypertensive cerebrovascular disease.

Abstract
BACKGROUND AND AIMS Heart failure (HF) is a growing concern worldwide. S100A1 and zinc α2-glycoprotein (ZAG) play an important role in heart function. We examined serum levels of S100A1 and ZAG in HF patients and their association with anthropometric indices and body composition. METHODS AND RESULTS Sixty-four patients with HF, mean age 56.2, 48 male and 16 females, with ejection fraction <30-35%, were recruited from Shahid Madani Heart Hospital in Tabriz, Iran, from April to October 2019. Two groups, cachexia (n = 32) and non-cachexia (n = 32), which were divided based on weight loss of at least 7.5% in the last six months, were compared with the control group (n = 26). S100A1 and ZAG serum levels were determined by ELISA. Serum median (min-max) levels of S100A1 and ZAG were significantly greater in HF patients [326 (184.8-635.2) and 150.4 (61.5-520.7)] than healthy controls [265.4 (43.6-658.8) and 119.8 (16.7-533)], both p = 0.001. S100A1 Serum levels in cachexia group was significantly higher than non-cachexia group [331 (245.6-469.6) vs. 318 (184.8-635.2), p = 0.03]. A strong positive association was observed between S100A1 and ZAG serum levels in patients (r = 0.70, p < 0.0001). Serum levels of these two proteins negatively and significantly associated with BMI (r = -0.25, p = 0.044 and r = -0.28, p = 0.024, respectively) and arm circumference (r = -0.26, p = 0.037 and r = -0.25, p = 0.047, respectively). CONCLUSION The results indicate that S100A1 and ZAG are likely to contribute to the pathogenesis of HF disease and weight loss, as well as the strong association between S100A1 and ZAG possibly indicating a similar mechanism of action for these two proteins.

Abstract
Modern advances in technology such as next-generation sequencing and digital PCR make detection of minor circulating cell-free tumor DNA amounts in blood from cancer patients possible. Samples can be obtained minimal-invasively, tested for treatment-determining genetic alterations and are considered to reflect the genetic constitution of the whole tumor mass. Furthermore, tumor development can be determined by a time course of the quantified circulating cell-free tumor DNA. However, systematic studies which prove the clinical relevance of monitoring patients using liquid biopsies are still lacking. In this study, we collected 115 samples from 47 late stage melanoma patients over 1.5 years alongside therapy-associated clinical routine monitoring. Mutation status was confirmed by molecular analysis of primary tumor material. We can show that detectable levels of circulating cell-free tumor DNA correlate with clinical development over time. Increasing levels of circulating cell-free tumor DNA during melanoma treatment with either targeted therapy (BRAF/MEK inhibitors) or immunotherapy, during recovery time or the intervals between last treatment cycle and second-line treatment point towards clinical progression before the progression becomes obvious in imaging. Therefore, this is a further possibility to closely screen our patients for tumor progression during therapy, in therapy-free phases and in earlier stages before therapy initiation.

Abstract
OBJECTIVE To review a literature about possible new blood serum gynecologic tumor markers, S100 proteins family, trefoil factor 3 and AIF-1. DESIGN Literature review. SETTING Department of Obstetrics and Gynecology, Faculty of Medicine, Palacky University and University Hospital in Olomouc. METHODS Literature review of articles published in PubMed database till January 2019. RESULTS The association of S100A2, S100A4, S100A6, S100A7, S100A8, S100A9 and S100A11 with breast carcinoma has been demonstrated in the literature. The association of S100A2, S100A4, S100A6, S100A7A, S100A10, S100A14, S100A16, S100B, S100P (up-regulation associated with a lower survival) and S100A1, S100A13, S100A5, S100A13 and S100G proteins (up-regulation associated with a better survival) have been demonstrated in ovarian cancer patients. Cervical carcinoma has been shown to be associated with the S100A9 protein. TFF3 association with endometrial cancer, breast cancer (worse prognosis) and ovarian cancer (better prognosis) has been demonstrated. AIF-1 has been shown to increase expression in cervical cancer. CONCLUSION Tumor markers can be a very useful tool for patient management when used appropriately. Further research in this area and the search for new tumor markers, including S100, TFF3 and AIF-1, are needed. In future studies, scientists should focus not only on one time point, but assess the trend of the tumor markers for a specific time axis.

Abstract
S100 proteins are currently being investigated as potential diagnostic and prognostic biomarkers of several cancers and inflammatory diseases. The aims of this study were to analyse the plasma levels of S100A4, S100A8/9 and S100A12 in patients with incomplete systemic lupus erythematosus (iSLE), in patients with established SLE and in healthy controls (HCs) and to investigate the potential utility of the S100 proteins as diagnostic or activity-specific biomarkers in SLE. Plasma levels were measured by ELISA in a cross-sectional cohort study of 44 patients with SLE, 8 patients with iSLE and 43 HCs. Disease activity was assessed using the SLEDAI-2K. The mean levels of all S100 proteins were significantly higher in SLE patients compared to HCs. In iSLE patients, the levels of S100A4 and S100A12 but not S100A8/9 were also significantly higher compared to HCs. There were no significant differences in S100 levels between the iSLE and SLE patients. Plasma S100 proteins levels effectively discriminated between SLE patients and HCs. The area under the curve (AUC) for S100A4, S100A8/9 and S100A12 plasma levels was 0.989 (95% CI 0.976-1.000), 0.678 (95% CI 0.563-0.792) and 0.807 (95% CI 0.715-0.899), respectively. S100 levels did not differentiate between patients with high and low disease activity. Only the S100A12 levels were significantly associated with SLEDAI-2K and with cSLEDAI-2K. S100 proteins were significantly higher in SLE patients compared HCs and particularly S100A4 could be proposed as a potential diagnostic biomarker for SLE.

Abstract
BACKGROUND Numerous articles related to S100 proteins have been recently published. This review aims to introduce this large protein family and its importance in the diagnostics of many pathological conditions in children and adults. DATA SOURCES Based on original publications found in database systems, we summarize the current knowledge about the S100 protein group and highlight the most important proteins with focus on pediatric use. RESULTS The S100 family is composed of Ca2+ and Zn2+ binding proteins, which are present only in vertebrates. Some of these proteins can be used as diagnostic markers in cardiology (S100A1, S100A12), oncology (S100A2, S100A5, S100A6, S100A14, S100A16, S100P, S100B), neurology (S100B), rheumatology (S100A8/A9, S100A4, S100A6, and S100A12), nephrology and infections (S100A8, S100A9, S100A8/A9, S100A12). The most useful S100 proteins in pediatrics are S100A8, S100A9, heterodimers S100A8/A9, S100B and S100A12. CONCLUSIONS The S100 family members are promising biomarkers and provide numerous possibilities for implementation into clinical practice to optimize the differential diagnostic process.

Abstract
Aims and Background Although there is no established tumor marker of proven value for patients with melanoma, high serum levels of S-100B protein have been found in patients with melanoma and distant metastases. This study was performed to assess the prognostic value of this marker. Methods and Study Design Serum S-100B protein was measured by means of the LIA-mat System 300 (Sangtec S-100B LIA, AB Sangtec Medical, Bromma, Sweden) in 85 patients with melanoma. Results Mean serum S-100B protein was 0.075 μg/L (range, 0.001-0.470) in 66 patients with non-metastatic melanoma (stage I-III) versus 0.441 μg/L (range, 0.001-16.840) in 19 patients with metastatic melanoma (stage IV) (P <0.001, Mann Whitney U test). The median follow-up time was 329 days. Serum levels above 0.150 μg/L were found in 10 of patients with non-metastatic melanoma (15.2%) and in 17 of 19 patients with metastatic disease (89.4%). Median survival was 256 days for the 27 patients with serum S-100B levels above 0.150 μg/L versus 561 days for the 58 patients with normal values (P <0.3973). Conclusion Serum S-100B is a useful tumor marker in melanoma.

Abstract
The S-100 family of proteins are acidic calcium and zinc binding low molecular weight proteins mainly present in astrocytes and in a population of oligodendrocytes of the CNS. S100b, an acidic low weight and zinc binding protein, has attracted considerable interest due to its release into the cerebrospinal fluid and blood from brain tissue following brain damage and from malignant melanomas. A new simple two-step incubation assay has now been elaborated in which two catcher and one tracer monoclonal antibodies are used. The specificity of this assay is high because all the MAbs used bind exclusively to S-100B, as shown by real-time biospecific interaction analyses. Moreover, the working range of the assay is 0.2–60 μg/L with a CV of less than 10%; the resulting high sensitivity has been confirmed by clinical studies. Time dependence, shaking conditions, lower limit of detection limits, effects of dilution, hook effect, recovery, impression as intra- and interassay variations, and crossreactivities with S-100A1 were tested in order to obtain a highly reproducible assay. Sera from healthy blood donors and patients undergoing cardiopulmonary bypass operations were tested with the assay. Several of the patients undergoing open heart surgery presented measurable values in this IRMA S-100 assay, indicating cerebral effects of open heart surgery. The test may be used for postoperative monitoring of these patients.

Abstract
Background S-100B determination has been shown to be clinically useful in the management of melanoma patients. After the development of a test for determination of the isoforms S100-A1B and S100-BB in serum (S-100B), several sensitive assays for the detection of serum S-100B have become available. We compared four S-100B assays, two automated (LIAISON®Sangtec®100 and Elecsys®S100) and two manual ones (Sangtec®100 ELISA and CanAg S100 EIA), with respect to clinical data, reference values and correlation. Methods In a total of 280 samples from 155 melanoma patients and 98 healthy individuals S-100B values were measured simultaneously with the different assays. Results The inter and intra coefficients of variation were best for the automated assays. The functional sensitivity of both manual assays was 0.15 μg/L. Method comparison revealed satisfactory correlation coefficients of 0.9 or higher, but the slopes ranged from 0.29 to 3.36. Except for the Sangtec®100 ELISA, the linearity between the assays was acceptable. The overall sensitivity for melanoma ranged from 37% (Elecsys®S100) to 47% (LIAISON®Sangtec®100) and the sensitivity increased with stage. ROC curves showed the best accuracy for the LIAISON®Sangtec®100 assay. Conclusions All assays gave satisfactory results, but it is advisable to improve the performance of the manual assays for better sensitivity. Agreement about an international reference standard is needed.

Abstract
BACKGROUND Central nervous system (CNS) complications such as seizures and reduced consciousness are important in glufosinate and may occur in severe glyphosate poisoning. The aim of this study was to assess the possible role of serum S100B protein as a biochemical marker of CNS complications associated with glyphosate or glufosinate poisoning. METHODS The study enrolled 40 patients (23 glyphosate poisoning and 17 glufosinate poisoning). Altered consciousness and seizure were observed during hospitalization. S100B level was measured with fully automated modular analytic E170 system using electrochemoluminometric immunoassay. RESULTS Among 40 patients, neurologic features were observed in 12 patients with a median time to onset of 21.5 (IQR 8.25-24.75) h. Serum S100B concentrations measured on admission were higher in the group with neurologic features than in the group without neurologic features [0.148 μg/L (IQR 0.128-0.248) vs. 0.072 μg/L (IQR 0.047-0.084), p < .001]. Univariate analysis of measured patient raw parameters using a ROC curve showed that S100B was a significant predictor of neurologic features in glyphosate and glufosinate poisoning. The area under the ROC curve was 0.894 (95% confidential interval 0.791-0.998). When S100B was set at 0.0965, its sensitivity and specificity for predicting neurologic features in glyphosate and glufosinate poisoning were 92% and 82%, respectively. CONCLUSIONS In our pilot study, S100B was a significant predictor of neurologic complications in patients with glyphosate and glufosinate poisoning. Large prospective cohorts are needed to confirm this finding.

Abstract
S100A6 protein belongs to the A group of the S100 protein family of Ca2+-binding proteins. It is expressed in a limited number of cell types in adult normal tissues and in several tumor cell types. As an intracellular protein, S100A6 has been implicated in the regulation of several cellular functions, such as proliferation, apoptosis, the cytoskeleton dynamics, and the cellular response to different stress factors. S100A6 can be secreted/released by certain cell types which points to extracellular effects of the protein. RAGE (receptor for advanced glycation endproducts) and integrin β1 transduce some extracellular S100A6's effects. Dosage of serum S100A6 might aid in diagnosis in oncology.

Abstract
Background In order to improve injury assessment of brain injuries, protein markers of pathophysiological processes and tissue fate have been introduced in the clinic. The most studied protein “biomarker” of cerebral damage in traumatic brain injury (TBI) is the protein S100B. The aim of this narrative review is to thoroughly analyze the properties and capabilities of this biomarker with focus on clinical utility in the assessment of patients suffering from TBI. Results S100B has successfully been implemented in the clinic regionally (1) to screen mild TBI patients evaluating the need to perform a head computerized tomography, (2) to predict outcome in moderate-to-severe TBI patients, (3) to detect secondary injury development in brain-injured patients and (4) to evaluate treatment efficacy. The potential opportunities and pitfalls of S100B in the different areas usually refer to its specificity and sensitivity to detect and assess intracranial injury. Conclusion Given some shortcomings that should be realized, S100B can be used as a versatile screening, monitoring and prediction tool in the management of TBI patients.

Abstract
BACKGROUND Identification of serum and bronchoalveolar lavage fluid (BALF) biomarkers may facilitate diagnosis and prognostication in various lung disorders. OBJECTIVE Serum and BALF levels of surfactant protein A (SP-A), surfactant protein D (SP-D), Clara cell protein 16 (CC16), S100 protein, trefoil factor 3 (TFF3), and prostatic secretory protein 94 (PSP94) were evaluated in 94 consecutive patients (idiopathic pulmonary fibrosis (IPF; n=18), sarcoidosis (n=25), chronic obstructive pulmonary disease (COPD; n=51)), and in 155 healthy controls. METHODS Biomarkers were measured at diagnosis and compared with disease characteristics. Both uniparametric and multiparametric analyses were used. RESULTS Seven significant correlations were found: 1) BALF PSP94 level correlated with prognosis of sarcoidosis (P=0.035); 2) BALF SP-D level with pulmonary functions in IPF (P=0.032); 3) BALF SP-D and TFF3 with IPF mortality (P=0.049 and 0.017, respectively); 4) serum TFF3 level with COPD mortality (P=0.006,); 5) serum SP-A with pulmonary functions impairment in IPF (P=0.011); 6) serum SP-D level was associated with HRCT interstitial score in IPF (P=0.0346); and 7) serum SP-A was associated with staging of COPD according to spirometry (P<0.001). Moreover, our analysis showed that some biomarker levels differed significantly among the diseases: 1) BALF SP-D level differed between sarcoidosis and IPF; 2) serum SP-A level differed among IPF, sarcoidosis, COPD and was also different from healthy controls; 3) serum S100A6, S100A11 levels differed among IPF, sarcoidosis, COPD from healthy controls 4) serum SP-D, CC16, TFF-3 levels distinguished IPF patients from healthy controls; and 5) serum CC16, TFF3, PSP94 distinguished COPD patients from healthy controls. Our study shows that some of selected biomarkers should have prognostic value in the analysed lung disorders. On the other hand, these biomarkers do not appear to be unequivocally suitable for differential diagnosis of these disorders.

Abstract
OBJECTIVE To investigate the protective effects of high-dose ulinastatin on the vital organs in patients undergoing total arch replacement for type A aortic dissection. METHODS Between September 2014 and March 2016, 66 patients with type A aortic dissection underwent total arch replacement at our center. Thirty-six of the patients received ulinastatin treatment at 300 000 U/8 h from admission to 3 days postoperatively and at 300 000 U/2 h during cardiopulmonary bypass surgery (UTI group), and the other 30 patients did not receive perioperative ulinastatin treatment (control group). The surgical data and blood biochemistry profiles on days 1, 3, and 5 postoperatively were compared between the two groups, and the postoperative ICU stay, re-operation for bleeding, ventilation for over 7 days, ultrafiltration for postoperative renal failure, tracheotomy, incidences of pulmonary and neurological complications and hospital death were also compared. RESULTS s The operating time, cardiopulmonary bypass time, ACP time, cardiac arrest time, the lowest rectal temperature and frequency of bilateral and unilateral antegrade selective cerebral perfusion were similar between the two groups (P>0.05). Compared with those in the control group, patients in UTI group had lower lactate, S-100 and neuron specific enolase levels on the first postoperative day and higher OI on the 1st, 3rd, and 5th postoperative days (P<0.05), but serum creatinine, blood urea nitrogen, total bilirubin, and alanine aminotransferase levels were comparable between the two groups (P>0.05). No significant differences were found in the frequency of re-operation for bleeding, ultrafiltration for renal failure, tracheotomy, neurological complications or hospital death after the operation between the two groups, but the patients in UTI group had a shorter ICU time, a less frequent long-term ventilation and a lower incidence of pulmonary infection (P<0.05). CONCLUSION High-dose ulinastatin offers protection on pulmonary function and lowers the specific brain injury markers in patients with type A aortic dissection after total arch replacement, but its protective effects on brain is uncertain.

Abstract
The S100B protein is associated with brain damage and a breached blood–brain barrier. A previous pilot study showed that high serum levels of S100B are associated with shorter survival in glioma patients. The aim of our study was to assess the prognostic value in terms of survival and longitudinal dynamics of serum S100B for patients with newly diagnosed and recurrent glioma. We obtained blood samples from patients with newly diagnosed and recurrent glioma before the start (baseline) and at fixed time-points during temozolomide chemotherapy. S100B-data were dichotomized according to the upper limit of the reference value of 0.1 μg/L. Overall survival (OS) was estimated with Kaplan–Meier curves and groups were compared with the log rank analysis. To correct for potential confounders a Cox regression analysis was used. We included 86 patients with newly-diagnosed and 27 patients with recurrent glioma. Most patients in both groups had baseline serum levels within normal limits. In the newly diagnosed patients we found no significant difference in OS between the group of patients with S100B levels >0.1 μg/L at baseline compared to those with <0.1 μg/L. In the patients with recurrent glioma we found a significantly shorter OS for patients with raised levels. In both groups, S100B values did not change significantly throughout the course of the disease. Serum S100B levels do not seem to have prognostic value in newly diagnosed glioma patients. In recurrent glioma patients S100B might be of value in terms of prognostication of survival.

Abstract
Objective: The two most commonly used heparin-coated systems for cardiopulmonary bypass (CPB) are the Carmeda Bio-Active Surface (CBAS) (Medtronic, Minneapolis, MN, USA) and the Duraflo II coating (Baxter Healthcare, Irvine, CA, USA). The two surfaces are technically unequal and previous experimental studies have demonstrated disparities in effects on the immune system and blood cells. However, little is known concerning the influence of the two surfaces on markers for brain and myocardial dysfunction. Methods: Forty patients undergoing elective, primary coronary bypass grafting with CPB were prospectively randomized to either the CBAS system or the Duraflo II circuit. During and after CPB, biological markers for brain dysfunction and myocardial injury were analysed. Results: Both markers for brain dysfunction S-100B and neuron-specific enolase (NSE) increased significantly during CPB ( p =0.01). The elevation during bypass correlated significantly with the duration of CPB ( r = 0.39 and r= 0.38, respectively, both p< 0.02). NSE was somewhat more elevated in the Duraflo II group at the end of CPB ( p =0.01) and 5 h after CPB ( p= 0.02); for S-100B, there were no intergroup differences. Also, the markers related to myocardial injury, myoglobin and creatine kinase (CK-MB) mass increased during CPB ( p= 0.01), while elevation of troponin-I occurred 5 h after CPB ( p= 0.01). There were no statistically significant intergroup differences. No significant correlation was seen between the release of cardiac markers and the duration of CPB. The clinical course was similar in both groups. Conclusions: Except for a slightly higher elevation of NSE at the end of CPB and 5 h after CPB in the Duraflo II group, there were no significant differences between the CBAS group and the Duraflo II group concerning markers for brain and myocardial dysfunction.

Abstract
OBJECTIVE To explore the expression level of neuron-specific enolase (NSE), S100B and neuropeptide Y (NPY) in children with acute miliary tuberculosis and secondary tubercular meningitis. PATIENTS AND METHODS 28 children diagnosed with acute miliary tuberculosis and secondary tubercular meningitis were included into group A, 25 children diagnosed with pure acute miliary tuberculosis were included into group B and 23 children diagnosed with suspected meningitis were included into group C. The levels of NSE, S100B and NPY in cerebrospinal fluid and serum were detected. RESULTS The levels of NSE, S100B and NPY in cerebrospinal fluid and serum of group A were significantly higher than the levels in the other two groups, differences were statistically significant (p<0.05). A multifactor retrospective analysis suggested that secondary tubercular meningitis was significantly correlated with the high expression of S100B, NPY and NSE in cerebrospinal fluid and serum. CONCLUSIONS Early detection of the expression levels of NSE, S100B and NPY in cerebrospinal fluid and serum was of great value for the diagnosis of tubercular meningitis secondary to acute miliary tuberculosis.

Abstract
This study examined the value of blood marker S100A1 in detecting cardiotoxicity induced by chemotherapy agents; trastuzumab and lapatinib, in normal rat heart. The rats were divided into three groups: control (n = 8, no treatment), T (n = 8, one time ip treatment with 10 mg/kg trastuzumab) and L (n = 8, oral treatment with 100 mg/kg/day lapatinib for 7 days). The activities of oxidative stress parameters Malondialdehyde (MDA), Superoxide dismutase (SOD), Catalase (CAT) and Glutathione (GSH) were measured from the extracted cardiac tissues. The levels of troponinI and S100A1 expressions were measured from blood samples. All biomarkers responded to the treatments as they exhibited alterations from their normative values, validating the chemically induced cardiotoxicity. S100A1 expression attenuated significantly (75%), which made the sensitive detection of cardiotoxicity feasible. Assessment of cardiotoxicity with S100A1 may be a valuable alternative in clinical oncology of cancers in some organs such as breast and prostate, as they do not overexpress it to compete against.

Abstract
OBJECTIVE Primary hyperparathyroidism (PHPT) has been associated with low-grade inflammation and increased risk of cardiovascular disease (CVD). The aim of the study was to investigate systemic levels of pro-inflammatory proteins that previously have not been examined in patients with PHPT. The selection of the pro-inflammatory biomarkers included in this study, MMP9, S100A4, S100A8/A9 and the receptors sCD14 and RAGE, was based on a previous microarray screen of mRNAs in adipose tissue from PHPT patients. DESIGN A prospective study was conducted on a total of 57 patients with PHPT and a control group of 20 healthy blood donors. METHODS PHPT patients with normalisation of serum calcium levels after parathyroidectomy were followed for 6 months. Forty-two patients participated in the longitudinal study, in which blood samples were taken at inclusion, and 1, 3 and 6 months after surgery. RESULTS We observed increased serum levels of MMP9 (P=0.029), S100A4 (P<0.001) and sCD14 (P=0.002) in the 57 patients with PHPT compared to the control-group. During 6 months of follow up, S100A4 (P=0.022) and sCD14 (0.002) decreased significantly, while serum levels of MMP9 increased (P=0.025). CONCLUSIONS The results demonstrate an increased inflammatory response in PHPT patients shown by elevated MMP9, S100A4 and sCD14 at inclusion. During the 6 months of follow-up, MMP9 increased further, possibly due to the tissue repair process after parathyroidectomy. S100A4 and sCD14 decreased after surgery demonstrating a partial reversal of the systemic inflammation.

Abstract
OBJECTIVE Myocardial infarction causes significant mortality and morbidity. Timely diagnosis allows clinicians to risk stratify their patients and select appropriate treatment. Biomarkers have been used to assist with timely diagnosis, while an increasing number of novel markers have been identified to predict outcome following an acute myocardial infarction or acute coronary syndrome. The objective of this study was to determine S100A4 expression in AMI and determine whether S100A4 could be a biomarker for detection of acute myocardial infarction (AMI). PATIENTS AND METHODS We measured circulating S100A4 levels in 173 patients (median age 58.3 years) who presented with first-time AMI 8 hours after the incident. The circulating S100A4 levels in 173 healthy volunteers (median age 57.3 years) was also measured. S100A4 was detected using enzyme immunoassay in both groups. RESULTS Serum S100A4 levels were significantly higher in patients with AMI [89.6 (4.3-214.6) pg/ml] compared to controls [11.8 (0-41.5) pg/ml] (p < 0.001). We found that a S100A4 level > 41.5 pg/ml had a Sensitivity 76.3% and specificity 87.5% for predicting AMI. S100A4 revealed the higher sensitivity for diagnosing AMI. CONCLUSIONS Elevated S100A4 in plasma may be a novel biomarker for early detection of AMI.

Abstract
Langerhans cell sarcoma (LCS) is a rare tumor with markedly malignant cytological features originating from Langerhans cells. LCS diagnosis is difficult and requires differentiation from other malignant tumors and Langerhans cell histiocytosis (LCH). Immunochemical antibodies, such as langerin, S-100 protein, and CD1a, have been used to diagnose LCS, but the results are crossed with LCH. To determine more significant biomarkers of LCS, we studied the expression and distribution pattern of Wilms tumor 1 (WT1) and cluster of differentiation 44 (CD44) in LCS. A broad panel of antibodies was used for immunohistochemical technology. Simultaneously, dual immunofluorescence staining examination and fluorescence in situ hybridization staining methods were used to study the location of WT1 and CD44 in LCS tumor cells. The results showed that tumor cells expressed WT1, CD44, and other special Langerhans cell markers (langerin, CD1a, and S-100 protein). LCS cells in all the cases showed normal cytogenetic findings without overexpression of WT1 and CD44. The expression of WT1 and CD44 was observed on langerin tumor cells by dual immunofluorescence staining examination in LCS. Our results suggest that WT1 and CD44 are potential biomarkers for LCS diagnosis. Clear understanding of their functional roles may further explain the pathogenesis of this highly malignant tumor and develop some novel immunotherapy strategies.

Abstract
AIM: To evaluate the diagnostic and prognostic value of circulating Metastasis Associated in Colon Cancer 1 (MACC1) transcripts in plasma of gastric cancer patients.
METHODS: We provide for the first time a blood-based assay for transcript quantification of the metastasis inducer MACC1 in a prospective study of gastric cancer patient plasma. MACC1 is a strong prognostic biomarker for tumor progression and metastasis in a variety of solid cancers. We conducted a study to define the diagnostic and prognostic power of MACC1 transcripts using 76 plasma samples from gastric cancer patients, either newly diagnosed with gastric cancer, newly diagnosed with metachronous metastasis of gastric cancer, as well as follow-up patients. Findings were controlled by using plasma samples from 54 tumor-free volunteers. Plasma was separated, RNA was isolated, and levels of MACC1 as well as S100A4 transcripts were determined by quantitative RT-PCR.
RESULTS: Based on the levels of circulating MACC1 transcripts in plasma we significantly discriminated tumor-free volunteers and gastric cancer patients (P < 0.001). Levels of circulating MACC1 transcripts were increased in gastric cancer patients of each disease stage, compared to tumor-free volunteers: patients with tumors without metastasis (P = 0.005), with synchronous metastasis (P = 0.002), with metachronous metastasis (P = 0.005), and patients during follow-up (P = 0.021). Sensitivity was 0.68 (95%CI: 0.45-0.85) and specificity was 0.89 (95%CI: 0.77-0.95), respectively. Importantly, gastric cancer patients with high circulating MACC1 transcript levels in plasma demonstrated significantly shorter survival when compared with patients demonstrating low MACC1 levels (P = 0.0015). Furthermore, gastric cancer patients with high circulating transcript levels of MACC1 as well as of S100A4 in plasma demonstrated significantly shorter survival when compared with patients demonstrating low levels of both biomarkers or with only one biomarker elevated (P = 0.001).
CONCLUSION: Levels of circulating MACC1 transcripts in plasma of gastric cancer patients are of diagnostic value and are prognostic for patient survival in a prospective study.

Abstract
PURPOSE OF REVIEW This review summarizes biomarkers in systemic juvenile idiopathic arthritis (sJIA). Broadly, the markers are classified under protein, cellular, gene expression and genetic markers. We also compare the biomarkers in sJIA to biomarkers in cryopyrin-associated periodic syndrome (CAPS). RECENT FINDINGS Recent publications showing the similarity of clinical response of sJIA and CAPS to anti-interleukin 1 therapies prompted a comparison at the biomarker level. SUMMARY sJIA traditionally is classified under the umbrella of juvenile idiopathic arthritis. At the clinical phenotypic level, sJIA has several features that are more similar to those seen in CAPS. In this review, we summarize biomarkers in sJIA and CAPS and draw upon the various similarities and differences between the two families of diseases. The main differences between sJIA and CAPS biomarkers are genetic markers, with CAPS being a family of monogenic diseases with mutations in NLRP3. There have been a small number of publications describing cellular biomarkers in sJIA with no such studies described for CAPS. Many of the protein marker's characteristics of sJIA are also seen to characterize CAPS. The gene expression data in both sJIA and CAPS show a strong upregulation of innate immunity pathways. In addition, we describe a strong similarity between sJIA and CAPS at the gene expression level in which several genes that form a part of the erythropoiesis signature are upregulated in both sJIA and CAPS.

Abstract
A short-cut review was carried out to determine whether protein S100B either alone or incorporated into clinical guidelines could be used to identify accurately those adults with mild head injury who had significant brain trauma. Thirty-five papers were found using the reported searches, of which nine presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of those best papers are shown in table 3. It is concluded that while S100B is a sensitive test for traumatic brain injury, there is no evidence to determine whether it adds value to any current clinical guidelines.

Abstract
BACKGROUND The aim of this study was to develop an adjunctive, peripheral biomarker test to differentiate ischemic strokes, intracranial hemorrhages (ICHs), and stroke mimics in the acute setting. METHODS Serum samples were collected from 167 patients who presented with an acute neurologic deficit within 24 hours of symptom onset. Patients were adjudicated to ischemic stroke, ICH, and mimic pathology groups based on clinical and radiographic findings. Samples were tested for levels of 262 potential markers. A multivariate Cox proportional hazards regression model of 5 biomarkers was built by stepwise selection and validated by bootstrapping. Its discriminative capacity was quantified by C index and net reclassification improvement (NRI). RESULTS The final model consisted of eotaxin, epidermal growth factor receptor, S100A12, metalloproteinase inhibitor-4, and prolactin. It demonstrated a discriminative capacity for ischemic stroke versus mimic (C = .92), ischemic stroke and ICH versus mimic (C = .93), and ischemic stroke versus ICH (C = .82). The inclusion of biomarkers to a model consisting of age, race, and gender resulted in an NRI of 161% when detecting ischemic stroke versus mimic (P < .0001), an improvement of 171% when detecting ischemic strokes plus ICH versus mimic (P < .0001), and an improvement of 56% when detecting ischemic strokes versus ICH (P = .1419). CONCLUSIONS These results suggest that information obtained from a 5-biomarker panel may add valuable information in the early evaluation and management of patients with stroke-like symptoms.

Abstract
OBJECTIVES Receptor for advanced glycation end products (RAGE) ligands/RAGE interactions have been proposed to have a pathogenic role in neuroinflammatory disorders. Our study aimed to assess changes in high-mobility group box (HMGB)1 and its receptor RAGE in peripheral blood (PBL) and cerebrospinal fluid (CSF) of patients with multiple sclerosis (MS) at the disease onset compared with control subjects. METHODS PBL and CSF were collected from control subjects (n = 30) and MS patients (n = 27) at clinical onset. Soluble RAGE (sRAGE), HMGB1, S100 calcium-binding protein A12 (S100A12), interleukin (IL)-1β and tumor necrosis factor (TNF)-α were measured in the CSF and plasma by enzyme-linked immunosorbent assay. Gene expression in PBL mononuclear cells (PBMCs) was detected by quantitative PCR for RAGE, HMGB1, S100A12 and several proinflammatory/immunoregulatory cytokines. RESULTS We found a significantly lower expression of IL-10 (p = 0.031) in the PBMCs of MS patients. The level of sRAGE in the CSF of MS patients was lower (p = 0.021), with the ability to discriminate between MS patients and control subjects. Moreover, PBMC gene expression for HMGB1 and S100A12 positively correlated with IL-6. CONCLUSIONS Our study confirmed that the cytokine network is disturbed in PBL and CSF at MS clinical onset. The deregulated HMGB1/RAGE axis found in our study may present an early pathogenic event in MS, proposing sRAGE as a possible novel therapeutic strategy for MS treatment.

Abstract
Background Soluble RAGE (sRAGE) has been associated with multiple inflammatory responses including maternal chorioamnionitis and preeclampsia. Analysis of umbilical cord blood levels have also indicated that sRAGE levels in the infant are affected by maternal inflammation. S100b is a ligand for RAGE and increases in circulating S100b levels are associated with poor neurological outcome in preterm infants. The objective of this study was to determine whether sRAGE or s100b levels in plasma samples from extremely preterm infants at the end of the first week of life were correlated with infant morbidities and whether sRAGE and s100b levels at this time point were still associated with maternal inflammation. Methods Plasma samples were collected from 130 preterm infants (≤28 weeks) at days of life 5, 6, or 7. sRAGE and s100b levels were measured by ELISA and data were analyzed by Pearson’s correlation or Generalized Estimating Equations. Results sRAGE was negatively correlated with development of sepsis (p=0.024), the FiO2 requirement of the infant at the time of sampling (p=0.030), as well as maternal preeclampsia (p=0.046), and positively correlated with maternal chorioamnionitis (p=0.006). s100b levels were positively associated with maternal chorioamnionitis (p=0.039). No correlations were observed with other infant morbidities. Conclusion These data indicate that sRAGE could potentially be a biomarker of early severe inflammatory responses in the preterm infant. However, more studies are needed to confirm the present findings.

Abstract
BACKGROUND Prognostic factors of melanoma with distant metastasis and systemic treatment are only poorly established. This study aimed to analyse the impact of S100B, lactate dehydrogenase (LDH) and the type of treatment on survival in advanced patients receiving systemic treatment. PATIENTS AND METHODS We analysed overall survival of 499 patients from the university department of dermatology in Tuebingen, Germany, with unresectable melanoma at the time point of initiation of first-line systemic therapy. Only patients who started treatment between the years 2000 and 2010 were included. Disease-specific survival was calculated by bivariate Kaplan Meier survival probabilities and multivariate Cox hazard regression analysis. RESULTS In univariate analysis LDH, S100B, the site of distant metastasis (soft tissue vs. lung vs. other visceral), the presence of brain metastases and the type of treatment (monochemotherapy, polychemotherapy, immunotherapy or biochemotherapy) were associated with overall survival (all p<0.001). In multivariate analysis LDH (Hazard ratio [HR] 1.6 [1.3-2.1]; p<0.001), S100B (HR 1.6 [1.2-2.1]; p<0.001) and the presence of brain metastases (HR 1.5 [1.1-1.9]; p = 0.009), but not the type of treatment had significant independent impact. Among those factors normal S100B was the best indicator of long-term survival, which was 12.3% after 5 years for this subgroup. CONCLUSION Serum S100B is a prognostic marker predicting survival at the time of initiation of first-line treatment in unresectable melanoma patients. Compared to the other independent factors LDH and the presence of brain metastases it is most appropriate to predict long-term survival and requires further prospective investigation in patients treated with new and more potent drugs in metastatic melanoma.

Abstract
PURPOSE To investigate predictive powers of S100B and cell-free DNA (cfDNA) levels in patients in the intensive care unit (ICU) who have with intracranial hemorrhage (ICH) for prognosis. METHODS Ninety-nine patients diagnosed with ICH were included in the study. The blood samples were drawn on the day of admittance to ICU and again on the third day. Duration of stay in the ICU and mortality were recorded. RESULTS A positive correlation was determined between the values of S100B and cfDNA from both the analysis and the Acute Physiology and Chronic Health Evaluation II scores. For all patients, there was a positive correlation between the duration of stay in the ICU and the values of S100B and cfDNA on the third day. The levels of both S100B and cfDNA in patients who died in the ICU were significantly higher than of those who survived on the day of admittance. CONCLUSIONS Both S100B and cfDNA values can be used as markers to predict the prognosis of ICU patients with ICH. However, S100B is more powerful for predicting the prognosis.

Abstract
The paper presents the results of neurospecific proteins S-100 and glial fibrillary acidic protein (GFAP) determination in blood serum samples of 145 neuro-oncology patients and 69 healthy people. The significant elevation of S-100 and GFAP was revealed in glioblastoma (G IV) patients compare to the patients with anaplastic astrocytoma (G III), benign meningioma (GI), celebral metastasis and healthy controls. The concentration of S-100 in blood serum of patients with anaplastic astrocytoma, benign meningioma, and celebral metastasis did not significantly differ among themselves, and in relation to the control group there was a significantly increase only in patients with cerebral metastasis. GFAP was characterized by high frequency of its detection in patients with glioblastoma (83%) compare to other groups of patients and healthy donors, in which it was practically undetectable. These data suggest the possibility of using GFAP as a marker of glioblastoma and S-100- as an additional biochemical criteria of cerebral lesions in oncology patients.

Abstract
OBJECTIVE To study the clinical effects of hypoxia preconditioning (HPC) and its effects on serum neuroglobin (NGB) and S-100B level in the patients undergoing intracranial aneurysm surgery. METHODS Forty patients scheduled to intracranial aneurysm surgery were randomly.divided into 2 groups: HPC group (n= 20) and control group (n= 20). The patients in HPC group were treated with 3 cycles of deoxidation-reoxygenation after intubation. The time of deoxidation in each HPC cycle was recorded, while vital signs were also recorded in each corresponding time point. Blood samples were obtained from exsanguinate radial artery and jugular bulb section at the end of each HPC cycle and corresponding time points during operation to measure serum level of NGB and S100B protein and to analysis blood gas. RESULTS During HPC process, the patients in group HPC experienced mild hypoxia and CO2 retention. With the times of HPC increasing, CO2 retention degree became heavier (P<0. 05) while hypoxia improved, the patients need more time to make SpO2 from 100% to 90% (P<0. 05). From T2 to T4 (the end of the third reoxygenation, during skull opened and aneurysm dipped, skull closed), NGB in group HPC was higher than that in control (P<0. 05), but S-100B level was not different between HPC and control group (P>0. 05). CONCLUSION HPC could induce compensatory ability of the body to hypoxia, which might be related to the up-regulation of NGB expression.

Abstract
PURPOSE Inflammation plays a critical role in the pathogenesis of obstructive sleep apnea syndrome (OSAS). S100A12 is a newly identified inflammatory biomarker. This study aims to investigate whether serum S100A12 levels are associated with the presence and severity of OSAS in male patients. METHODS A total of 126 male patients with OSAS and 74 controls were enrolled in this study. The presence and severity of OSAS was assessed by apnea-hypopnea index (AHI). Serum S100A12 levels were detected by enzyme-linked immunosorbent assay. RESULTS Serum S100A12 levels were significantly higher in the OSAS group than in the control group (132.17 (range 101.86 to 174.49) ng/ml vs. 78.40 (range 58.35 to 129.44) ng/ml, P < 0.01). Multivariate logistic regression demonstrated that S100A12 was the only significant and independent predictor of OSAS (odds ratio 1.012, 95% confidence interval 1.006 to 1.017; P < 0.01). Serum S100A12 levels elevated with the increase in the severity of OSAS (S100A12 levels of 106.04 (range 83.92 to 135.13) ng/ml in mild OSAS group, 133.51 (range 109.64 to 208.95) ng/ml in moderate OSAS group, and 173.04 (range 131.88 to 275.77) ng/ml in severe OSAS group; P < 0.001). Serum S100A12 levels were independently correlated with AHI scores (r = 0.324, P < 0.001) CONCLUSIONS: Serum S100A12 levels were independently associated with the presence and severity of OSAS. These findings suggest that serum S100A12 level could be a potential biomarker for reflecting the presence and severity of OSAS.

Abstract
Serum levels of neuron specific enolase (NSE) and protein S-100 were analysed in 22 patients with depression, who got repetitive transcranial magnetic stimulation (rTMS) for 3 weeks with ultra high frequency stimulation or sham. NSE and S-100 at baseline and after 3 weeks did not differ between the groups. Neither in the ultra high frequency group, nor in the sham group a difference between baseline and end could be found. No evidence for a significant rise in brain damage markers in rTMS was found in this preliminary study.

Abstract
Pathological classification of malignant melanoma did not change in the past decade, it was just completed with UV-induced skin alterations. A new feature, however, is the establishment of molecular classification of melanoma indicating that beside the most frequent genetic alterations (BRAF, NRAS, CKIT mutations) there is a wide variety of rare molecular subclasses. Unfortunately, none of these genetic alterations can be used to discriminate benign lesions from malignant ones. The frequently used "melanoma" markers are mostly melanosomal markers, therefore they are not helpful for this diagnostic purpose either. More recently, novel FISH kits have been developed analyzing characteristic copy number alterations specific for malignant melanoma. Though melanosomal markers are helpful in differencial diagnostics, the presence of normal melanocytes in various tissues (lymph nodes, intestine or brain) requires application of molecular techniques when melanoma metastasis is in question.

Abstract
OBJECTIVES To determine the ability and accuracy of the S-100β protein in predicting prognosis after a moderate or severe traumatic brain injury. DESIGN Systematic review and meta-analysis of randomised controlled trials and observational studies. DATA SOURCES Medline, Embase, Cochrane Central Register of Controlled Trials, BIOSIS (from their inception to April 2012), conference abstracts, bibliographies of eligible articles, and relevant narrative reviews. STUDY SELECTION Two reviewers independently reviewed citations and selected eligible studies, defined as cohort studies or randomised control trials including patients with moderate or severe traumatic brain injury and evaluating the prognostic value of S-100β protein. Outcomes evaluated were mortality, score on the Glasgow outcome scale, or brain death. DATA EXTRACTION Two independent reviewers extracted data using a standardised form and evaluated the methodological quality of included studies. Pooled results were presented with geometric means ratios and analysed with random effect models. Prespecified sensitivity analyses were performed to explain heterogeneity. RESULTS The search strategy yielded 9228 citations. Two randomised controlled trials and 39 cohort studies were considered eligible (1862 patients). Most studies (n=23) considered Glasgow outcome score ≤ 3 as an unfavourable outcome. All studies reported at least one measurement of S-100β within 24 hours after traumatic brain injury. There was a significant positive association between S-100β protein concentrations and mortality (12 studies: geometric mean ratio 2.55, 95% confidence interval 2.02 to 3.21, I(2)=56%) and score ≤ 3 (18 studies: 2.62, 2.01 to 3.42, I(2)=79%). Sensitivity analysis based on sampling time, sampling type, blinding of outcome assessors, and timing of outcome assessment yielded similar results. Thresholds for serum S-100β protein values with 100% specificity ranged from 1.38 to 10.50 µg/L for mortality (six studies) and from 2.16 to 14.00 µg/L for unfavourable neurological prognosis as defined by the Glasgow outcome score. CONCLUSIONS After moderate or severe traumatic brain injury, serum S-100β protein concentrations are significantly associated with unfavourable prognosis in the short, mid, or long term. Optimal thresholds for discrimination remain unclear. Measuring the S-100β protein could be useful in evaluating the severity of traumatic brain injury and in the determination of long term prognosis in patients with moderate and severe injury.

Abstract
OBJECTIVE This study aimed to explore the ability of the serum marker S100B to predict the development and severity of postconcussion syndrome (PCS) at 3 months in children after mild traumatic brain injury (mTBI). METHODS This is a retrospective analysis of a prospective observational study conducted in a pediatric emergency department (ED). Children were eligible for the study if they were between the ages 5 and 18 years, presented within 6 hours of injury, met the case definition of mTBI from American Congress of Rehabilitation Medicine, had a Glasgow Coma Scale score of greater than 13, consented to have blood drawn for S100B levels, and completed the 3-month telephone follow-up. At the follow-up, the Rivermead Postconcussion Questionnaire was conducted to determine the development and severity of PCS. RESULTS A total of 76 children were included in this cohort. The children had a mean (SD) age of 14.0 (3.1) years, 60.5% were male, and 89.5% had a Glasgow Coma Scale of 15. Twenty-eight (36.8%) developed PCS. For the children who developed PCS, the mean (SD) S100B level was 0.092 (0.376) µg/L. For children who did not develop PCS (n = 48), the mean (SD) S100B level was 0.022 (0.031) µg/L. The analyses did not support an association between initial S100B levels measured in the ED and development of PCS or severity of PCS symptoms. CONCLUSIONS In this small sample, S100B, measured immediately after injury in the ED, did not seem to predict those children with mTBI who will go on to develop PCS.

Abstract
OBJECTIVE To determine the optimal dose of colloid preload, which is both safe and effective, for preventing hypotension in parturients undergoing cesarean section under spinal anesthesia. METHODS Forty-five healthy, termed parturients scheduled for cesarean delivery under spinal anesthesia were randomly assigned to 3 colloid preload groups to receive gelofusine infusion at the rates of 5, 10, or 15 ml·kg(-1)·h(-1) (groups I, II, and III, respectively). Colloid preload was administered 10 min before spinal anesthesia and maintained until the delivery. Blood pressure (BP) and heart rate (HR) of the parturients were monitored during the operation, and Apgar scores at 1 and 5 min after birth were recorded. S100β protein concentration and blood gas values of the umbilical artery were also measured. The vascular adaptation in the placental villous capillary was evaluated stereologically. RESULTS At each time point of measurement, BP and HR showed no significant differences among the 3 groups during the operation (P>0.05), but within the same group, BP and HR underwent significant variations during the operation; groups II and III maintained more stable hemodynamics compared to group I. Apgar scores and blood gas analysis, pH value, and S100β protein in the umbilical artery showed no significant differences among the 3 groups (P>0.05). The 3 groups exhibited no significant differences in the length and volume density of the placental villous capillaries (P>0.05). CONCLUSION Colloid preload with gelofusine administered at the rate of 10 ml·kg(-1)·h(-1) can reduce the incidence and severity of hypotension in cesarean section under spinal anesthesia with the least adverse maternal and fetal effects.

Abstract
BACKGROUND Osmotherapy is a cornerstone for the management of severe Traumatic Brain Injury (TBI). Hypertonic saline (HTS) has advantages as being preferred osmotic agent, but there is inadequte knowledge regarding dose and its saftey in comparison to mannitol. S100B, as a specific neuroinflammatory biomarker in TBI might be a reliable therapeutic index following osmotic therapy. AIM To compare both administration ways of HTS 5% (bolus and infusion) with mannitol upon S100B as a therapeutic tool for monitoring treatment in TBI patients. METHOD Adult patients wih modrate to severe TBI were recruited and have randomly received one of the three protocols: 125 cc of HTS 5% every 6 hrs (N: 11) as bolus; 500 cc of HTS 5% (N: 12) as infusion for 24 hrs; or 1 g/kg mannitol of 20% (N: 10) as a bolus, repeated with a dose of 0.25-0.5 g/kg every 6 hrs based on patient's response for 3 days. Serum S100B, blood pressure, serum sodium and osmolality and Glascow coma score (GCS) were measured at baseline and daily for 3 days. RESULTS Initial serum S100B level in TBI patients was higher than control group (p < 0.0001). Levels of measured S100B have decreased for all treatment groups, but reduction wasn't significantly after hyperosmolal therapy. GCS level increased significantly in infusion group (p = 0.002) and there were negative and significant correlation between serum S100B level and GCS level in some days. Mean arterial pressure increased significantly in HTS groups (bolus: p = 0.002, infusion < 0.0001). CONCLUSIONS S100B is closely related to the pathophysiological mechanism in TBI and may be useful as a therapeutic tool for treatment monitoring in TBI patients HTS is a safe and effective osmotic agent in TBI setting.

Abstract
S100B is a calcium-binding protein most abundant in neuronal tissue. It is expressed in glia cells and Schwann cells and exerts both intra- and extracellular effects. Depending on the concentration, secreted S100B exerts either trophic or toxic effects. Its functions have been extensively studied but are still not fully understood. It can be measured in cerebrospinal fluid and blood, and increased S100B level in blood can be seen after, e.g., traumatic brain injury, certain neurodegenerative disorders and malignant melanoma. This chapter provides a short background of protein S100B, commercially available methods of analysis, and its clinical use.

Abstract
INTRODUCTION Concussion cannot be differentiated from superficial scalp injury, especially in inebriated or uncooperative patients. This can have serious medical or forensic consequences. The aim of the study was to determine whether serum concentrations of S-100b in mild traumatic brain injury (MTBI) patients are significantly higher than those in patients with superficial scalp injury with scalp wound and alcohol intoxication. MATERIAL AND METHODS A total of 50 patients with head injury, 25 with mild concussion without scalp wound and alcohol intoxication, 25 superficial scalp injury patients with scalp wound and clinical signs of inebriety. Neurological status and cranial CT scan were evaluated 60-120 minutes after injury in all the 50 patients to exclude focal cerebral injury or skull fracture. RESULTS The serum levels of S-100b were significantly increased in patients with concussion (median 0.36 ± 0.15 μg/l ) in comparison with the group of patients with scalp injury and alcohol intoxication (median 0.09 ± 0.002 μg/l). All 50 patients had a normal cranial CT finding and neurological status. In all superficial scalp injury patients alcohol intoxication was confirmed (0.96 - 3.11š). CONCLUSION We proved significantly higher values of S-100b in patients with brain concussion. Diagnostically decisive value of S-100b concentration in the serum was set at 146 μg/l and higher (94% sensitivity and 100% specificity). Alcohol intoxication (up to 3.11 š) and scalp wound seem to have had no crucial impact on serum S-100b level.

Abstract
Background Aneurysmal subarachnoid hemorrhage (aSAH) is a devastating condition that frequently causes death or significant disabilities. Blood tests to predict possible early complications could be very useful aids for therapy. The aim of this study was to analyze serum levels of kallikrein 6 (KLK6) in individuals with aSAH to determine the relevance of this protease with the outcome of these patients. Methodology/Principal Findings A reference interval for KLK6 was established by using serum samples (n = 136) from an adult population. Additionally, serum samples (n = 326) from patients with aSAH (n = 13) were collected for 5 to 14 days, to study the concentration of KLK6 in this disease. The correlation between KLK6 and S100B, an existing brain damage biomarker, was analyzed in 8 of 13 patients. The reference interval for KLK6 was established to be 1.04 to 3.93 ng/mL. The mean levels in patients with aSAH within the first 56 hours ranged from 0.27 to 1.44 ng/mL, with lowest levels found in patients with worse outcome. There were significant differences between patients with good recovery or moderate disability (n = 8) and patients with severe disability or death (n = 5) (mean values of 1.03 ng/mL versus 0.47 ng/mL, respectively) (p<0.01). There was no significant correlation between KLK6 and S100B. Conclusions/Significance Decreased serum concentrations of KLK6 are found in patients with aSAH, with the lowest levels in patients who died.

Abstract
The purpose of our study was to investigate the association between perioperative cerebral microembolization, expressed as high-intensity transient signals (HITS) and postoperative dynamics of the neuromarker S100P in patients operated using cardiopulmonary bypass, and to assess their impact upon the neurocognitive function in the early postoperative stage. The study involved 62 consecutive male patients aged 60 or above, alls scheduled for elective aortocoronary bypass. The patients were recruited from two groups with respect to the use of CPB: on-pump group (CPB+, N = 30) and off-pump group (CPB-, N = 32). In all patients we performed intraoperative monitoring of cerebral haemodynamics using transcranial Doppler, with the goal of quantifying perioperative cerebral microembolization. The serum levels of the neuromarker S100l were measured immediately after surgery, and then 12, 24 and 48 hours after the surgery. Neurocognitive status was assessed before and after the surgery and in three cognitive domains. Results of the study have shown that with respect to the short-term postoperative neurocognitive outcome there is no significant difference between the on-pump and off-pump surgical technique of coronary revascularization'. Perioperative cerebral microembolization was significantly more pronounced in the on-pump group yet it did not affect early postoperative neurocognitive function, while the increase in the neuromarker S100beta serum level 48 hours after surgery may have prognostic value as a predictor of postoperative neurocognitive dysfunction.

Abstract
OBJECTIVE Patients undergoing cardiac surgery are at risk for postoperative cognitive dysfunction (POCD). Evaluating preoperative risk factors represents 1 possible way to minimize the postoperative risk of cognitive dysfunction. We investigated marked deterioration in cholinergic neurotransmission as 1 such potential risk factor for transient and long-lasting POCD. Serum anticholinergic activity (SAA) has already been described as a risk factor for developing delirium in an elderly study population. However, the role of SAA for long-lasting POCD is unknown. METHODS Following local ethics board approval and written informed consent, we recruited a cohort of patients aged ≥ 55 years undergoing cardiac surgery. Before surgery, levels of SAA were measured and a battery of neuropsychologic tests (NPTs) was applied. S100 calcium binding protein ß concentration was measured intraoperatively. Pre-, intra-, and postoperative patient-specific characteristics were recorded. The NPTs were repeated 3 months after hospital discharge to evaluate 3-month POCD. A group of nonsurgical patients (n = 34) was recruited as control subjects to adjust NPT scores, using reliable methods for the change index. Logistic multivariate regression was used to evaluate independent predictors of POCD. RESULTS One hundred fifty-four patients were screened before surgery, and 117 completed the second NPT. POCD was identified in 25.6% of patients. In contrast to intraoperatively increased S100 calcium binding protein ß, preoperative SAA was not associated with POCD following adjustment for covariates. CONCLUSIONS Preoperatively increased SAA did not predict POCD 3 months after cardiac surgery.
