Abstract Colorectal cancer (CRC) represents one of the most common cancers. It is frequently diagnosed at advanced stages, indicating on need for new diagnostic markers. Th e aim of this study was to determine systemic and fecal values of IL- 17 and IL-33 in patients with CRC and the relationship with clinicopathological aspects of disease. Th e blood samples and feces liquid fraction of 50 patients with CRC were analyzed. Serum and fecal levels of IL-33 and IL-17 were measured using sensitive enzyme-linked immunosorbent assay (ELISA) kits. Fecal levels of IL-33 and IL-17 were increased in CRC patients with poor tumor tissue diff erentiation. Serum IL-33 and fecal IL-17 were increased in patients with presence of lung/liver metastasis or peritoneal carcinomatosis, respectively, while enhanced fecal IL-33 was detected only in patients with peritoneal carcinomatosis. Positive correlation between IL-33 and IL-17 values in sera and feces, respectively was also observed. We believe that increased local values of IL-33 and IL-17, reflected trough higher fecal concentration, in CRC patients with poor tumor tissue differentiation and with presence of lung/liver metastasis or peritoneal carcinomatosis may be considered as a sign of the tumor’s malignant progression and, consequently, of a poor prognosis for patients.

Background. Adenoviruses are highly contagious pathogens which cause respiratory disease particularly in children; they may induce severe disease in infants. Human neutrophil peptides (HNPs) have been found to exhibit antiadenoviral activity. Thus, we have investigated HNPs in nasal aspirates (NAs) of children suffering from adenoviral common cold. Objective. To investigate the release of HNP-1–4 in adenovirus infection and the relationship with self-limiting upper respiratory tract infections. Methods. Nasal aspirate samples (n=14) were obtained from children (aged 6–12 years) infected with adenovirus between June 2012 and December 2015. Control samples were taken 4 weeks after infection when the children were asymptomatic. Levels of HNPs were measured using an enzyme-linked immunosorbent assay (ELISA). Results. There were increased levels of HNP-1, -3, and -4, but not HNP-2, in nasal aspirates (NAs) during adenovirus infections compared to healthy specimens (p≤0.01). Moreover, there was also increase in the neutrophil count, which is a known cell source of HNPs. Conclusion. Our finding supports the involvement of HNP-1, -3, and -4 in naturally occurring cold in children infected with adenovirus. Because of their known antiviral properties, it is tempting to hypothesize that HNPs might play a protective role in adenovirus-induced respiratory disease; however, this remains to be shown.

SummaryPeritoneal carcinomatosis from colorectal cancer is associated with a poor prognosis and is usually treated with systemic chemotherapy and immunotherapy alone. In patients with isolated peritoneal carcinomatosis (PC) without nonperitoneal metastases, however, cytoreductive surgery (CRS) has been shown to significantly improve outcome and to achieve even cure in selected patients in combination with systemic therapy. The additional use of a hyperthermic intraperitoneal chemotherapy (HIPEC) is primarily indicated to control microscopical residual tumor tissue in the peritoneal cavity after successful CRS. Another more recent option is the application of an adjuvant HIPEC to prevent peritoneal carcinomatosis in high risk patients with pT4 cancer or perforated cancer at the time of or after primary surgery. The aim of this short review is to highlight the corresponding available literature and assess the role of CRS and HIPEC in the context of modern chemotherapy and immunotherapy.

Equine Infectious Anemia (EIA) disease is caused by EIA Virus (EIAV) from genus Lentivirus, subfamily Orthoretrovirinae, family retroviridae. This virus causes a persistent infection and potentially fatal in Equidae. There is no scientific literature yet for this disease in Indonesia. In order to determine this disease in our country, it is necessary continuing laboratory detection in imported Equidae and conducted further surveillance in Equidae throughout Indonesia. This research is aimed (1) to detect of any antibodi titre of EIAV in imported horse, (2) To get information about the relationship between laboratory result with the secondary datas of origin country. The EIAV antibody detected by indirect enzyme-linked immunosorbent assay (indirect ELISA). The secondary datas were collected from Health Certificate of origin country, World Animal Health Information System (WAHIS) Interface OIE and literatures. Total of 133 blood samples were collected from imported horse, ex-imported horse and lokal breed horse. The result showed that all of imported horse, ex-imported horse and lokal breed horse were negative antibody against EIAV. The initial information on Equine Infectious Anemia indicated that health requirement in imported horse has fulfilled, so that imported horse was free from EIAV.

e14521 Background: Gastric cancer (GC) is the second leading cause of cancer death in China. Liver metastasis (LM) is a highly frequent event of the advanced GC, and the patients with LM always present dismal prognosis. A predicted factor of LM is urgently established to screen out the population in high risk of LM. Tumor-derived exosomes play critical roles in cancer metastasis process. Exosomes integrin (ITG) αvβ5 is uptake by liver resident cells and linked to LM in cell lines. This study is designed to evaluate the association between exosomes ITG αvβ5 and liver metastasis, especially in HER2 positive gastric cancer. Methods: 74 untreated advanced GC patients with matched blood and tumor tissue samples and clinical features were collected in the study. Exosomal HER2, ITG αv and β5 expression were measured by enzyme-linked immunosorbent assay (ELISA) after the exosomes isolated from plasma. HER2 status of tumor tissue was determined by IHC and/or FISH. Results: Based on HER2 status of tumor tissue, we initially proved the feasibility of detecting HER2 expression from exosome. ROC curves showed the optimum exosomal HER2 expression diagnostic cutoff for HER2 positive patients was 266.38 pg/ml (sensitivity 71.4% and specificity 72.6%). In total, 27 patients were LM and the rest (n = 47) was non-LM. The median expression value of ITG αv and β5 were 57.55 pg/ml and 836.00 pg/ml, respectively. And these two median value were identified as the cutoff value for subsequent analysis, respectively. HER2 expression was merely linked to ITG β5 expression (P = 0.019), not ITG αv (P > 0.050). There was no relationship between ITG αv and LM (P = 0.629), however, ITG β5 expression presented significant association with LM (P = 0.016). We further probed the relationship between ITG and other metastasis. Results showed no correlation between any ITG and other non-liver organic metastases, like lung, bone, ovarian, lymph, and peritoneal metastasis. Besides, ITG β5 expression was also associated with LM in the HER2-positive GC patients. Conclusions: Exosomes might serve as a potential non-invasive diagnostic and screening tool. In clinical samples, ITG β5, not αv, was linked to LM, and might be a valuable biomarker in the use of predicting LM of GC, even in the HER2-positive patients.

Introduction. Gastric cancer (GC) represents one of the most common cancers worldwide, frequently diagnosed at advanced stages with poor prognosis, indicating on need for new diagnostic and prognostic markers. The aim of the study was to determine the expression of IL-32, proinflammatory and angiogenic mediators, in patients with diffuse and intestinal gastric cancer and the relationship with clinicopathological aspects. Material and Methods. The tissue samples of diffuse and intestinal types of tumor of 70 patients with gastric cancer were analyzed. Expression of IL-32, VEGF, IL-17, and CD31 was measured by immunohistochemistry. Results. IL-32 expression was significantly lower in tissue samples from patients with diffuse type of gastric cancer that is also a severe and more progressive form (TNM stages III and IV, poor histological differentiation, and higher nuclear grade III). Expression of IL-17 was also decreased in patients with diffuse type of gastric cancer. Microvascular density was diminished in diffuse type of gastric cancer. Conclusions. Downregulated expression of IL-32 in tumor tissue of patients with diffuse type of gastric cancer may implicate on its role in limiting ongoing proinflammatory and proangiogenic processes. This emphasizes on unrecognized role of IL-32 in biology of diffuse type of gastric cancer.

Background/Aim. Colorectal cancer (CRC) represents one of the most common cancers worldwide. CRC is frequently diagnosed at advanced stages with poor prognosis, indicating the need for new diagnostic and prognostic markers. The aim of this study was to determine systemic and fecal values of galectin- 1 (gal-1) and ratios between gal-1 and proinflammatory cytokines: tumor necrosis factor-alpha (TNF-?), interleukin-1 beta (IL-1?) and interferon gamma (IFN-?), in the patients with CRC and the relationship with clinicopathological aspects of the disease. Methods. The blood samples and feces liquid fraction of 58 patients with CRC were analyzed. The serum and fecal levels of TNF-?, IL-1? and IFN-? and gal-1 were measured using sensitive enzyme-linked immunosorbent assay (ELISA) kits. Results. The fecal level of gal-1 was increased in the CRC patients with higher nuclear grade and poor tumor tissue differentiation. The gal-1/TNF-? ratio in the serum and feces had a higher trend in the patients with the advanced tumor-nodemetastasis (TNM) stage as well as the detectable lymphatic and blood vessel invasion. The gal-1/TNF-? and gal-1/IFN-? ratios were increased in the serum of patients with presence of lung/liver metastasis or peritoneal carcinomatosis, while the enhanced gal-1/IL-1 ratio was detected only in the serum of patients with lung metastasis. A positive correlation between the gal-1 value in feces and histological differentiation of tumor and biomarkers alpha-fetoprotein (AFP) and cancer antigen- 19-9 (CA 19-9), respectively, was also observed. The fecal values of gal-1 higher than 13,708.29 pg/g presented a highly sensitive and specific marker for histological differentiation of tumor tissue. Conclusion. We believe that the predomination of gal-1 over pro-inflammatory cytokines TNF-?, IL-1? and IFN- ? in the patients with advanced and progressive CRC may implicate on an immunomodulatory role of gal-1 in the limiting ongoing proinflammatory processes. The fecal values of gal-1 can be used as a valuable marker for the severity of CRC.

Background: MicroRNAs (miRNA) are known to play a key role in the etiology and treatment of epilepsy through controlling the expression of gene. However, miR-125a-5p in the epilepsy is little known. Epilepsy in rat models was induced by Pentylenetetrazol (PTZ) and miR- 125a-5p profiles in the hippocampus were investigated in our experiment. Also, the relationship between miR-125a-5p and calmodulin-dependent protein kinase IV (CAMK4) was identified and the related mechanism was also illustrated. Methods: The miR-125a-5p mRNA expression levels were evaluated by quantitative real time polymerase chain reaction (qRT-PCR). Western Blot (WB) was used to analyze the CAMK4 protein expression levels. Seizure score, latency and duration were determined based on a Racine scale. The enzyme-linked immunosorbent assay (ELISA) was used to analyze the inflammatory factor expression. The relationship between miR-125a-5p and CAMK4 was detected through dual luciferase assay. Results: Downregulation of miR-125a-5p was observed in the hippocampus of PTZ-induced epilepsy rats. The overexpression of miR-125a-5p attenuated seizure and decreased inflammatory factor level in the hippocampus of PTZ-induced rats. The miR-125a-5p alleviated epileptic seizure and inflammation in PTZ-induced rats by suppressing its target gene, CAMK4. Conclusion: miR-125a-5p may represent a novel therapeutic treatment for PTZ-induced epilepsy by preventing the activation of CAMK4.

Background: Colony Stimulating Factor-1 Receptor (CSF-1R) is associated with malignancy, invasiveness and poor prognosis of tumors, and pyrimidine derivatives are considered as a novel class of CSF-1R inhibitor. Methods: To explore the relationship between the structures of substituted pyrimidine derivatives and their inhibitory activities against CSF-1R, CoMFA and CoMSIA analyses, and molecular docking studies were performed on a dataset of forty-four compounds. Results: We found in CoMFA model including steric and electrostatic fields for the training set, the cross-validated q2 value was 0.617 and the non-cross-validated r2 value was 0.983. While, the crossvalidated q2 value was 0.637 and the non-cross-validated r2 value was 0.984 in CoMSIA Model which include steric, electrostatic and hydrophobic fields. 3D equipotential maps generated from CoMFA and CoMSIA along with the docking binding structures provided enough information about the structural requirements for better activity. Conclusion: The data generated from the present study helped us to predict the activity of new inhibitors and further design some novel and potent CSF-1R inhibitors.

Lactate is a product of anaerobic glycolysis, used in animal research as an indicator of muscle fatigue. Therefore, it has been used as an indicator of cattle response to long distance transportation. The aim of this study was to assess the relationship of L-lactate concentrations measured using a Lactate Scout+ analyzer and a traditional lactate assay colorimetric kit. Blood samples were collected by venipuncture from 96 steers (Black or Red Angus × Hereford/Simmental and Black or Red Angus × Charolais; 247 ± 38.2 kg BW) prior to loading (LO1) and after 36 h of transport, and prior to reloading and after an additional 4 h of road transportation, and on d 1, 2, 3, 5, 14, and 28 after transport. The Lactate Scout+ analyzer strip was dipped in blood at the time of sampling, while blood samples were collected into sodium fluoride tubes for use in the colorimetric analysis. Pearson correlations were calculated to assess the strength of the relationship between the experimental methods for the quantification of L-lactate concentrations. The magnitude and direction of the correlation, and the level of statistical significance varied over the observed time points, ranging from r = −0.03 (p = 0.75; LO1) to r = 0.75 (p < 0.0001; d 3). The correlation for the pooled data was weak but statistically significant (r = 0.33, p < 0.0001). Based on the low magnitude of the correlation due to variability across sampling time points in this study, the Lactate Scout+ analyzer is not a suitable alternative to a lab-based assay (considered the gold standard) for measuring L-lactate in transported cattle.
