Phage Display–Derived Ligand for Mucosal Transcytotic Receptor GP-2 Promotes Antigen Delivery to M Cells and Induces Antigen-Specific Immune Response

Successful oral immunization depends on efficient delivery of antigens (Ags) to the mucosal immune induction site. Glycoprotein-2 (GP-2) is an integral membrane protein that is expressed specifically on M cells within follicle-associated epithelium (FAE) and serves as transcytotic receptor for luminal Ags. In this study, we selected peptide ligands against recombinant human GP-2 by screening a phage display library and evaluated their interaction with GP-2 in vitro and ex vivo. Selected peptides were conjugated to the C-terminal of enhanced green fluorescence protein (EGFP) and evaluated for their ability to induce an immune response in mice. One of our selected peptides, Gb-1, showed high binding affinity to GP-2 and, when fused to EGFP, significantly increased the uptake of EGFP by M cells compared to EGFP alone. After oral administration, the Gb1-EGFP fusion induced efficient mucosal and systemic immune responses in mice measured at the level of antigen-specific serum and fecal antibodies, cytokine secretion, and lymphocyte proliferation. Furthermore, the IgG subclasses and cytokine secretion showed that ligand Gb-1 induced a Th2-type immune response. Collectively, our findings suggest that the ligand we selected through phage library screening is capable of targeting Ags to GP-2 on M cells and can be used as an oral vaccine adjuvant.
Narcissism, political tenure, financial indicators and the effectiveness of environmental regulation

ABSTRACT This article explores the factors that determine the effectiveness of environmental regulation in the United States and Australia. Unlike prior literature, in which lagging performance measures (such as carbon emissions) are used, we use financial data to develop effectiveness scores and identify the determinants of effectiveness, including narcissistic behaviour, tenure of political leaders and financial indicators. Consistent with the emerging literature on environmental finance, we find that abnormal returns are associated with environmental regulation and that effectiveness is adversely affected when narcissistic leaders are in power. Our results remain robust when we control for various event windows and models.
The Tax Multiplier in the Netherlands: New Estimates from a Narrative Study

This paper studies the e↵ect of tax changes on output for the Netherlands between 1960 and 2015. I use the narrative record of parliamentary reports, the Budget Memorandum (BM) and Tax Plan to identify tax changes that are exogenous to output. Using simple OLS, I show that the e↵ect of tax on output is significant and contractionary, yet mostly in the same quarter as the introduction of a tax change. The output e↵ect has faded after two years. I estimate implied impact multipliers of around -0.9% of GDP and, depending on the model specification, a total multiplier of between -1% and -2% of GDP following a tax shock of 1% of GDP.
Differential Expression of Human Equilibrative Nucleoside Transporter 1 (hENT1) Protein in the Reed-Sternberg Cells of Hodgkin's Disease

Gemcitabine is a cytotoxic nucleoside analog with activity in relapsing/refractory Hodgkin's disease (HD). Because gemcitabine is hydrophilic, it requires plasma membrane nucleoside transporter proteins to access intracellular targets. The most abundant and widely distributed transporter in human cells is human equilibrative nucleoside transporter 1 (hENT1). Because our prior studies showed that a deficiency in hENT1 confers high-level resistance to gemcitabine toxicity in vitro, we developed an immunohistochemical method to assess the hENT1 abundance of cells in tumor tissue. We now report the application of this method for visualizing the hENT1 protein abundance in the plasma membranes of Reed-Sternberg cells in lymph nodes of HD patients. Frozen sections of 30 lymph nodes were stained with monoclonal antibodies (mAb 10D7G2) raised against a synthetic peptide comprised of residues 254-271 from the large intracellular loop of hENT1 and staining intensity was scored on a 0-4+ scale. hENT1-staining intensity varied among HD lymph node samples (score/ n ; 0/8; 1/10; 2/9; 3/3; 4/0) and suggested that at least 60% of the tumors appeared hENT1 deficient. Because Epstein-Barr virus (EBV) is often associated with HD, staining for Epstein-Barr early RNA was also examined. Although 9/30 patients tested positive for EBV, there was no correlation with hENT1 staining. hENT1-staining intensities were positively correlated with age of the patient but were independent of other clinical, laboratory or pathology features (tumor stage, histologic subtype, presence of B symptoms, staining for CD15 or CD30, serum biochemistry, disease free survival, and overall survival). We conclude that, because hENT1 deficiency has been previously related to nucleoside-drug resistance, immunohistochemical staining for hENT1 warrants evaluation as a predictive tool for guiding the appropriate use of gemcitabine in the treatment of HD.
Deep sequencing and variant analysis of an Italian pathogenic field strain of equine infectious anaemia virus

Equine infectious anaemia virus (EIAV) is a lentivirus with an almost worldwide distribution that causes persistent infections in equids. Technical limitations have restricted genetic analysis of EIAV field isolates predominantly to gag sequences resulting in very little published information concerning the extent of inter-strain variation in pol, env and the three ancillary open reading frames (ORFs). Here, we describe the use of long-range PCR in conjunction with next-generation sequencing (NGS) for rapid molecular characterization of all viral ORFs and known transcription factor binding motifs within the long terminal repeat of two EIAV isolates from the 2006 Italian outbreak. These isolates were from foals believed to have been exposed to the same source material but with different clinical histories: one died 53 days post-infection (SA) while the other (DE) survived 5 months despite experiencing multiple febrile episodes. Nucleotide sequence identity between the isolates was 99.358% confirming infection with the same EIAV strain with most differences comprising single nucleotide polymorphisms in env and the second exon of rev. Although the synonymous:non-synonymous nucleotide substitution ratio was approximately 2:1 in gag and pol, the situation is reversed in env and ORF3 suggesting these sequences are subjected to host-mediated selective pressure. EIAV proviral quasispecies complexity in vivo has not been extensively investigated; however, analysis suggests it was relatively low in SA at the time of death. These results highlight advantages of NGS for molecular characterization of EIAV namely it avoids potential artefacts generated by traditional composite sequencing strategies and can provide information about viral quasispecies complexity.
Evaluation of the Eosinophil-to-lymphocyte Ratio in Pediatric Patients with Allergic Rhinitis

Background Allergic rhinitis is a type 1 hypersensitivity reaction of the nasal mucosa, the primary mediator of which is immunoglobulin E. Allergic rhinitis occurs in children and adolescents. Objective This study examined the relationship between allergies and the eosinophil-to-lymphocyte ratio in children with allergic rhinitis with a positive skin-prick test. Study Design This study was planned and performed as a case-control study. Methods There were 695 patients who presented to our clinic who were enrolled in the study. Only group 4 fit the criteria for allergic rhinitis. Group 1 (nonsensitized asymptomatic [control group]), group 2 (nonsensitized symptomatic), group 3 (sensitized asymptomatic), and group 4 (sensitized symptomatic). The patients’ allergy symptoms and skin test results were assessed and compared. The eosinophil-to-lymphocyte ratio for each patient was calculated. The eosinophil and lymphocyte counts and the eosinophil-to-lymphocyte ratio were calculated for each group. Results The eosinophil-to-lymphocyte ratio and eosinophil counts in groups 3 and 4 were significantly higher (p < 0.001 and p < 0.001, respectively) than those in groups 1 and 2. The lymphocyte counts in groups 3 and 4 were significantly lower (p = 0.046) than those of groups 1 and 2. Conclusions The eosinophil-to-lymphocyte ratio may be used in conjunction with skin-prick testing in pediatric patients with allergic rhinitis. This parameter is inexpensive to measure and easy to use and calculate.
Investigating key innovation capabilities fostering visitors’ mindfulness and its consequences in the food exposition environment

ABSTRACT This study investigated the crucial innovation capability factors of an exposition in creating visitors’ mindfulness, and examined the effect of visitors’ mindfulness on memory formation and patronage intentions in the food exposition context. To test a conceptual model, a survey was conducted targeting participants in an international food exposition held in Busan, South Korea. The data from a total of 371 visitors were analyzed using structural equation modeling analysis. The results reveal that product-, environment-, and promotion-related subdimensions of innovation capability in a food exposition enhance visitors’ mindfulness. In addition, visitors’ mindfulness builds strong memories and patronage intentions with regard to food expositions. The study findings enrich our understanding of the innovation experience of exposition visitors and the role of mindfulness in the food exposition context. Practical implications are explored in the Discussion section.
Effect of Long-Term Continuous Fumigation on Soil Microbial Communities

High value crop producers in California rely heavily on soil fumigation to control a wide array of soil borne pests including nematodes, pathogens and weeds. Fumigants with broad biocidal activity can affect soil microbial communities that contribute to nutrient cycling and plant nutrient uptake which can impact soil health. It is often thought that soil microbial communities make a relatively rapid recovery following fumigation. However, recently it has been found that repeated application of fumigants over time can have greater and longer lasting impacts on soil microorganisms than single fumigation events. Therefore, the main objective of this study was to determine the effect of long-term repeated application of fumigants on soil microbial communities and compare them with non-fumigated and organic sites. Soil samples were collected from fields in Watsonville, CA. Chronosequence sites were defined by number of years of annual fumigation (yaf) with methyl bromide (15, 26, 33, 39 yaf) at the time of sampling, and representative non-fumigated sites were also included for comparison. Phospholipid fatty acid (PLFA) analysis was used to analyze the samples. The canonical variate analysis showed that microbial communities in sites with a longer history of fumigation (33 and 39 yaf) were similar to one another; however, they differed significantly from 15 yaf site and further analysis concluded that non-fumigated sites were significantly different than fumigated sites. This study showed that the proportion of arbuscular mycorrhizal fungi (AMF) was lower in all fumigated (15, 33 and 39 yaf) sites as compared to their non-fumigated counterparts, which could be a threat to sustainability since AMF plays a major role in soil health and quality.
A regenerative cascaded multilevel converter with reduced active front ends

This paper presents a new topology of cascaded multilevel converter which substitutes active front ends for the diode-based front ends only in part of cells making the converter regenerative. Its control strategy based on V/f control is developed. During the induction motor's deceleration, by controlling the phase difference of the output fundamental voltages of the two types of cells, the converter makes the electrical energy generated by the motor wholly collected by regenerative cells and thus other cells' DC-link voltages remain stable. A six-cell cascaded converter with three regenerative cells per phase is analyzed as an example. Simulation results show that the new converter can deliver the power generated by the motor back to the grid and the power quality is not substantially affected. An experiment on a laboratory cascaded converter verifies that the control strategy is feasible. Compared with the converter in which each cell has an active front end, the new converter has lower complexity and lower cost.
The impact of intuition and supervisor-nurse relationships on empowerment and affective commitment by generation.

AIM This article reports a generational cohort and leader-member exchange theoretical frameworks-guided study of the influence of the supervisor-subordinate relationship on three generational nurse cohorts' use of intuition, perceptions of empowerment and affective commitment. BACKGROUND Within a global context of nurse shortages, knowledge about factors influencing nurse retention is urgently sought. We postulated that nurses' use of intuition is the key to their empowerment and consequent commitment to the organization, and that impact would vary among the three large nurse generations. METHODS A self-report survey was used to gather data in 2008, which were then analysed using correlations, regression analysis, manova and path analysis. Data were obtained from 900 Baby Boomer and Generations X and Y nurses, randomly chosen from seven private hospitals across Australia. RESULTS The findings confirm the important impact of supervisor-nurse relationships upon all three generations' use of intuition. The findings add new knowledge about the differing importance of using intuition for Generation X, Generation Y and Baby Boomer nurses' perceptions of empowerment, suggesting it is more important to Baby Boomers and Generation X than to Generation Y. Further, the impact of using intuition differs significantly among the generational cohorts. CONCLUSIONS The findings suggest the need for a more differentiated tailored style - sensitive to varying needs of the generations. Improving supervisor-nurse relationships is also critical, because of their impact upon nurses' use of intuition, perceptions of empowerment and affective commitment. Poor relationships lead to increased nurse replacement costs.
Performance Analysis of ML Detection in MIMO Systems with Co-Channel Interference

In this letter, we analyse a receiver technique for MIMO systems with flat fading channel, in which the Co-Channel Interference (CCI) along with white Gaussian noise is modelled as correlated Gaussian noise. This correlated Gaussian noise is whitened and then Maximum likelihood detection (MLD) is performed over the desired user's streams. An upper bound on the bit error rate (BER) is derived to understand the performance of this approach. Using the upper bound, we show that the covariance matrix of the interference has to be rank deficient for the BER to reduce with SNR. Monte Carlo simulations are performed to verify the diversity order predicted by the upper bound.
Towards Drylands Biorefineries: Valorisation of Forage Opuntia for the Production of Edible Coatings

Species of the genus Opuntia may be a well-suited feedstock for biorefineries located in drylands, where biomass is scarcer than in humid or temperate regions. This plant has numerous uses in Mexico and Central America, and its mucilage is a specialty material with many promising applications. We extracted the mucilage from a forage species, O. heliabravoana Scheinvar, and mixed it with a thermoplastic starch to produce an edible coating. The coating was applied to blackberries, which were then evaluated in terms of several physicochemical and microbiological variables. During a 10-day evaluation period, the physicochemical variables measured in the coated fruits were not significantly different from those of the control group. However, the microbiological load of the coated fruits was significantly lower than that of the uncoated fruits, which was attributed to a decreased water activity under the edible coating. Multivariate analysis of the physicochemical and microbial variables indicated that the storage time negatively affected the weight and size of the coated and uncoated blackberries. Although some sensory attributes have yet to be optimised, our results support the use of the mucilage of forage Opuntia for the formation of edible coatings, as well as their valorisation through a biorefinery approach.
Agpat4/Lpaatδ deficiency highlights the molecular heterogeneity of epididymal and perirenal white adipose depots

Acylglycerophosphate acyltransferase 4 (AGPAT4)/lysophosphatidic acid acyltransferase delta catalyzes the formation of phosphatidic acid (PA), a precursor of triacylglycerol (TAG). We investigated the effect of Agpat4 gene ablation on white adipose tissue (WAT) after finding consistent expression across depots. Epididymal WAT mass was 40% larger in male Agpat4−/− mice than wild-type littermates, but unchanged in perirenal, retroperitoneal, and inguinal WAT and subscapular brown adipose tissue. Metabolic changes were identified in epididymal WAT that were not evident in perirenal WAT, which was analyzed for comparison. The total epididymal TAG content doubled, increasing adipocyte cell size without changing markers of differentiation. Enzymes involved in de novo lipogenesis and complex lipid synthesis downstream of phosphatidic acid production were also unchanged. However, total epididymal TAG hydrolase activity was reduced, and there were significant decreases in total ATGL and reduced phosphorylation of hormone-sensitive lipase at the S563 and S660 PKA-activation sites. Analysis of Agpats 1, 2, 3, and 5, as well as Gpats 1, 2, 3, and 4, demonstrated compensatory upregulation in perirenal WAT that did not occur in epididymal WAT. Our findings therefore indicate depot-specific differences in the redundancy of Agpat4 and highlight the molecular and metabolic heterogeneity of individual visceral depots.
Laboratory diagnosis of two scrub typhus outbreaks at Camp Fuji, Japan in 2000 and 2001 by enzyme-linked immunosorbent assay, rapid flow assay, and Western blot assay using outer membrane 56-kD recombinant proteins.

Two scrub typhus outbreaks occurred among U.S. Marines training at Camp Fuji, Japan, between October 25 and November 3, 2000 and October 17 and November 30, 2001. Nine cases in approximately 800 Marines in 2000 and eight cases in approximately 900 Marines in 2001 (approximate attack rates = 1.1% and 0.9%, respectively) reported with signs and symptoms of fever, rash, headache, lymphadenopathy, myalgia, and eschar. Serologies and rapid response to doxycycline treatment indicated they had scrub typhus. Sixty-four convalescent serum samples (18 suspected cases and 46 negative controls) from U.S. Marines training at Camp Fuji during the outbreaks were assessed by enzyme-linked immunosorbent assay (ELISA), rapid flow assay (RFA), and Western blot assay for evidence of infection with Orientia tsutsugamushi, the causative agent of scrub typhus. All but one suspected case had serologic evidence of scrub typhus and all 46 control sera were non-reactive to O. tsutsugamushi antigens. The recombinant 56-kD antigen (r56) from the Karp, Kato and Gilliam strains of O. tsutsugamushi in an ELISA format provided better results than Karp r56 alone (ELISA and RFA) or whole cell antigen preparation from Karp, Kato and Gilliam (ELISA).
A regulatory region from the mouse Hox-2.2 promoter directs gene expression into developing limbs.

To characterize cis-acting regulatory elements of the murine homeobox gene, Hox-2.2, transgenic mouse lines were generated that contained the LacZ reporter gene under the control of different fragments from the presumptive Hox-2.2 promoter. A promoter region of 3600 base pairs (bp) was identified, which reproducibly directed reporter gene expression into specific regions of developing mouse embryos. At 8.5 days postcoitum (p.c.) reporter gene activity was detected in posterior regions of the lateral mesoderm and, in subsequent developmental stages, expression of the LacZ gene was restricted to specific regions of the developing limb buds and the mesenchyme of the ventrolateral body region. This pattern of Hox-2.2-LacZ expression was found in all transgenic embryos that have been generated with the 3.6 kb promoter fragment (two founder embryos and embryos from five transgenic lines). In addition, embryos from two transgenic mouse lines expressed the reporter gene at low levels in the developing central nervous system (CNS). Our results are consistent with the idea that in addition to their presumptive role in CNS and vertebrae development, Hox-2.2 gene products are involved in controlling pattern formation in developing limbs.
Palliative care and hematological malignancies: increased referrals at a comprehensive cancer centre.

BACKGROUND Current evidence indicates that patients with hematological malignancies are less likely to receive input from specialist palliative care services compared to those with solid tumors. AIM We aimed to analyze data for referrals to our palliative care service, in order to assess trends in the number and proportion of referrals received from hematology, and changes in the characteristics of these referrals. DESIGN Prospective information was collected for all referrals to the Department of Pain and Palliative Care (DPPC) over a four-year period. This included inpatient/outpatient status, diagnosis, symptoms, and goals of the referring clinician; and information linked to hospital inpatient data to obtain date and location of death. SETTINGS/PARTICIPANTS All hematology referrals were from January 2007 to December 2010. RESULTS Hematology referrals constituted 11.6% of all referrals received during the study period. Outpatient referrals increased significantly with each year, as did the proportion of patients referred for symptom control. The median time from referral to death was 34 days, with poorest survival seen in acute leukemia and inpatients. Overall, 54% of inpatient hematology deaths had consultation from the DPPC, with these patients less likely to die in the intensive care unit. CONCLUSIONS Over recent years, collaboration between hematology and palliative care has resulted in increased referral numbers, with potentially positive results for patients.
