562). CONCLUSIONS Our data Indicated production of IL-4 in cultured PBMCs of CE patients stimulated with HCF-Ag was decreased significantly. While, production of IFN-γ was increased significantly in responses to HCF Ag after surgery. We concluded that the evaluation of IL-4 and IFN-γ in HCF-Ag stimulated PBMCs of CE patients should be considered as a useful marker in the follow up of patients with cystic echinococcosis. Stimulation with polyclonal activators is a tool to increase antibody secretion in B cells. The aim of the present study was to select the most effective common commercially available polyclonal activators of rabbit B cells. Specifically, type B oligodeoxynucleotides with unmethylated deoxycytidyl-deoxyguanosine dinucleotides (CpG-ODN), recombinant rabbit interleukin-2 (rrIL-2), lipopolysaccharide (LPS), pokeweed mitogen (PWM) and Resiquimod (R848) were tested on B cells isolated from blood and spleen by fluorescence-activated cell sorting. Based on the obtained data, stimulation with CpG-ODN induced the highest antigen-specific antibody levels detected by ELISA in supernatants when a single activator was used. In contrast, LPS, PWM and R848 showed a weak or no stimulatory effect. Stimulation with a mix of activators was more effective than CpG-ODN alone, which indicates a synergistic effect in the stimulation of antibody production. Cyprinid herpesvirus 3 (CyHV-3) is the etiological agent of koi herpersvirus disease (KHVD), which causes serious economic losses in global common carp and ornamental koi carp production of larvae as well as adult type fish. To control KHVD, vaccines against CyHV-3 utilizing different immunization routes have been developed, among them, oral vaccination is the most desirable method to prevent fish diseases occurring at the early larval stage. Here, we developed an oral subunit vaccine through the Saccharomyces cerevisiae cell surface display of CyHV-3 envelope protein pORF65, then, the recombinant yeast fed to Artemia which served as bio-encapsulation vector by subsequently feeding the common carp (Cyprinus carpio var. Jian) larvae. The fluorescent observation showed that the Artemia and S. cerevisiae could deliver intact antigen to the hindgut of carp larvae suggesting the possibility of the vector for oral immunization. On this basis, after three immunizations at a week interval, the oral vaccine induced high level of specific anti-pORF65 antibody. Meanwhile, a significant difference of immune-related genes expression occurred including cxca, IL-1β, IFN-a1, lysozyme, IgM and CD8α between vaccined group and blank control group. In addition, 30% of relative percent survival of carp larvae after immunization was obtained post the animal infection assay, offered an certain immune protection. Our results indicated that the oral pORF65 subunit vaccine bioencapsulated in Artemia induced the activation of immune response and high level of antibodies, which could be served as an oral vaccine candidate for the prevention of CyHV-3 infection. S. Pullorum is a causative agent of enteric disease of poultry with serious diarrhea. However, the detailed mechanism behind its injury to intestinal mucosa barrier, especially for intestinal stem cells, is unclear. In this study, S. Pullorum were orally administrated to 3 days old chicken to investigate the pathogenesis of S. Pullorum on intestinal mucosal barrier, especially on the proliferation of epithelial cells. We found that S. Pullorum could colonize in the cecum and invade into the liver through intestinal mucosa damage, which caused obvious pathological changes in liver and intestine and even leaded to death, as well as significant reduction of body weight. We also found that S. Pullorum infection enhanced the mRNA expression of IL-1β and IL-6 through TLR4/MyD88 pathway, which was also further verified by the increased lipopolysaccharide (LPS) levels in serum. Furthermore, S. Pullorum increased the depth of crypt and density of PCNA+ cells significantly through the over-activation of Wnt/β-catenin signaling pathway. The expression of intestinal stem cells markers Lgr5 and Bmi1 was also increased after S. Pullorum infection to support the crypt hyperplasia. In addition, we verified that S. Pullorum infection enhanced the mRNA expression of IL-1β, TLR4, Lgr5 and Bmi1. Our study indicated that S. Pullorum infection damaged the intestinal mucosa barrier to induce diarrhea, affected the abnormal proliferation of intestinal stem cells by over-activation of Wnt/β-catenin pathway in chicken. BACKGROUND Studies using administrative data commonly rely on diagnosis codes to identify venous thromboembolism (VTE) events. Our objective was to assess the validity of using International Classification of Disease, 9th Revision (ICD-9) codes in identifying recurrent VTE. MATERIALS AND METHODS Among 5497 adults with confirmed incident VTE from four healthcare delivery systems in the Cardiovascular Research Network (CVRN), we identified all subsequent inpatient, emergency department (ED), and ambulatory clinical encounters associated with an ICD-9 code for VTE (combined with relevant radiology procedure codes for inpatient/ED VTE codes in the secondary discharge position or outpatient codes) during the follow-up period. Medical records were reviewed using standardized diagnostic criteria to assess for the presence of new, recurrent VTE. The positive predictive value (PPV) of codes was calculated as the number of valid events divided by total encounters. RESULTS We identified 2397 encounters that were considered potential recurrent VTE by ICD-9 codes. However, only 31.1% (95%CI 29.3-33.0%) of encounters were verified by reviewers as true recurrent VTE. Hospital or ED encounters with VTE codes in the primary position were more likely to represent valid recurrent VTE (PPV 61.3%, 95%CI 56.7-66.3%) than codes in secondary positions (PPV 35.4%, 95%CI 31.9-39.3%), or outpatient codes (PPV 20.3%, 95%CI 18.3-22.5%). PPV was low for all VTE types (29.9% for pulmonary embolism, 38.3% for lower and 37.7% for upper extremity deep venous thrombosis, and 14.1% for other VTE). CONCLUSIONS ICD-9 codes do not accurately identify new VTE events in patients with a prior history of VTE. The formation of host-guest complex between benzyl isothiocyanate (BITC) and β-cyclodextrin (β-CD) was studied using dispersion-corrected density functional theory calculations. The complexation process was monitored using molecular docking simulations, natural bond orbital (NBO) technique, nuclear magnetic resonance (1H NMR) chemical shift calculations and non-covalent interactions (NCI) analysis. All these approaches are consistent with experimental findings. The calculated complexation energy was negative indicating the formation of inclusion complex. The most stable complexation of BITC involves the inclusion of its aromatic moiety in β-CD cavity (model A) in accord with experimental NMR chemical shift data. buy BAY-61-3606 The non-covalent interactions (NCI) based on the reduced density gradient (RDG) analysis reveal that mainly weak Van der Waals intermolecular interactions between BITC and β-CD provide and ensure stability for the complexation process. OBJECTIVES As health systems start to discuss alternative payment models for fostering value in healthcare, there is increased interest in understanding how physicians will cope with different remuneration schemes. We conducted a survey of physicians practicing at Hospital Israelita Albert Einstein, a nonprofit private healthcare provider in Brazil, aimed at capturing their awareness of value-based healthcare (VBHC). METHODS Our study uses data from a survey administered to doctors practicing at Einstein between September and November 2018. Descriptive statistics and adjusted multivariate logistic regression analyses were used to describe physicians' characteristics associated with their views on VBHC. RESULTS A total of 1000 physicians completed the survey (response rate 13%). Although only 25% knew the value equation, 67% defined value in health according to Porter's-the outcomes that matter to patients in relation to the costs of offering such outcomes. Most participants identified increased healthcare costs as the main reason for the discussions over new financing models. Only 27% of physicians rated their awareness of VBHC as high or very high. In the multivariate analysis, awareness of VBHC was associated with holding a management position, scoring high in the hospital's physician segmentation program, being familiar with the value equation, and attributing high importance to developing new VBHC financing models for health system transformation. CONCLUSIONS Physician awareness of key VBHC concepts is still heterogeneous in our clinical setting. Promoting opportunities for involving physicians in the discussion of VBHC is key for a successful value-driven transformation of healthcare. Can newborn brains perform one-shot learning? To address this question, we reared newborn chicks in strictly controlled environments containing a single view of a single object, then tested their object recognition performance across 24 uniformly-spaced viewpoints. We found that chicks can build view-invariant object representations from a single view of an object a case of one-shot learning in newborn brains. Chicks can also build the same view-invariant object representation from different views of an object, showing that newborn brains converge on common object representations from different sets of sensory inputs. Finally, by rearing chicks with larger numbers of object views, we found that chicks develop enhanced recognition for familiar views. These results illuminate the earliest stages of object recognition, revealing (1) powerful one-shot learning that builds invariant object representations from the first views of an object and (2) view-based learning that enriches object representations, producing enhanced recognition for familiar views. In order to improve the catalytic activity and recycling performance of heterogeneous Fenton catalyst, a heterogeneous Fenton catalyst Fe/TiO2 based on TiO2 supported visible light response was prepared by a simple method using TiO2 synthesized by sol-gel method as carrier and ferric nitrate as Fe source. It was characterized by SEM, EDX, XRD, UV-vis instruments. The influencing factors of catalytic degradation of atrazine by visible light heterogeneous Fenton of Fe/TiO2 were studied and the reaction kinetics were fitted. The mineralization degree of atrazine was reflected by the removal rate of TOC. The intermediate products by the degradation of the catalytic system was analyzed and the reaction mechanism of Fe/TiO2-H2O2 visible light system was discussed. The XRD results showed that Fe was highly dispersed on the surface of TiO2 in the form of α-Fe2O3. The Fe/TiO2 catalyst with heterogeneous Fenton and visible light photocatalytic activity was successfully optimized, forbidden bandwidth of Fe/TiO2 after Fe supported was narrower, the scope of light absorption red-shifted, the electron-hole pairs were more generated, and there was a significant synergistic effect between the carrier TiO2 and the supported Fe, which exhibited good oxidation capacity for degradation of 10 mg L-1 atrazine in pH of 3, the concentration of H2O2 was 1.6 mM, and the catalyst was added at 1 g L-1, achieving over 95% removal efficiency within 30 min, and, in the range of pH 3-7, the degradation rate of the reaction for 30 min can be maintained above 75%, which greatly broadened the range of pH application and had good recycling performance. The degradation process conformed to the quasi-first-order kinetic model. Through LC-MS analyzed, 12 intermediate products were formed during the degradation of atrazine, the final products were all cyanuric acid, and then the triazine ring was mineralized into inorganic substances such as CO2, H2O and NO3- by oxidation of ·OH, and the possible degradation pathways were inferred.
