Immunoglobulin A, G, and M responses to L1 and L2 capsids of human papillomavirus types 6, 11, 16, 18, and 33 L1 after newly acquired infection.

OBJECTIVES: We performed a study to establish the pattern of serological reactivity for immunoglobulins (Ig), to capsids of human papilloma virus (HPV) after new HPV infection in two groups of subjects. METHODS: The pattern of serological reactivity after acquisition of infection with HPV was investigated by measuring IgA, IgM, and IgG antibodies to capsids containing L1 and L2 proteins of HPV types 6, 11, 16, 18, and 33 in longitudinal studies of groups with different patterns of sexual activity. Individuals who tested negative for HPV DNA by the polymerase chain reaction at enrolment, but who became HPV DNA positive during follow up, were examined for antibodies to HPV capsids by enzyme linked immunosorbent assay. One group consisted of 15 young girls (with eight controls who remained HPV DNA negative) who were becoming sexually active and the other comprised 12 male (with five controls) and 35 female (with seven controls) heterosexual attenders of a sexually transmitted disease clinic who had had multiple sexual partners. RESULTS: The sexually inexperienced girls showed IgA and IgG responses, but seldom an IgM response to infection with HPV types 6/11, 16, and 18. No consistent pattern of serological reactivity was apparent for the heterosexuals with multiple partners. The lack of association between current HPV DNA positivity and detectable antibodies in these individuals was possibly related to the duration of infection or to prior exposure to HPV. For the latter group serological reactivity to HPV capsids was significantly greater in women than in men (p = 0.001, p = 0.003, and p = 0.024, for IgG to HPV 6, 11, and 16, respectively). CONCLUSION: The sex difference in antibody response detected in previous studies with assays based on peptide antigens was thus corroborated in the present study with capsid based serological assays. This sex difference might reflect a difference in sexual activity and prior exposure to HPV between men and women in this particular group.
Plasma glucose?insulin relationship in chicken lines selected for high or low fasting glycaemia

1. Selected Fat or Lean chickens differ in their plasma glucose-insulin relationship: in the fed or fasted state, Fat chickens have a lower glycaemia associated with normal or higher insulinaemia, depending upon the difference in glycaemia. 2. Conversely, chickens selected for low fasting glycaemia (LG) are fattier than their counterparts selected for high fasting glycaemia (HG), although the divergence in fat content is lower than in the Fat-Lean model. 3. The plasma glucose-insulin relationship has been investigated in males of the HG and LG lines in the F4 and F5 generations. 4. A difference in glycaemia is suggested during embryonic development and was present at hatching and later on in the fasted or the fed state; insulinaemia did not differ. 5. During refeeding after an overnight fast, glycaemia differed between lines (except at intermediate times); cumulative food intake and insulinaemia were similar. 6. During a glucose tolerance test, glucose disposal rate and insulinaemia were rather similar. 7. Exogenous insulin exerted a very similar hypoglycaemic effect in both lines. 8. Other variables (body temperature, plasma concentrations of potassium and α NH2-non protein nitrogen) did not differ between HG and LG chickens. 9. In conclusion, HG and LG chickens do not exhibit any differences in glucose disposal rate, insulinaemia (in various nutritional conditions) or sensitivity to exogenous insulin, which contrasts with Fat or Lean chickens and may explain why HG and LG chickens have diverged to a lesser extent in fat content.
A synthesis of the effects of pesticides on microbial persistence in aquatic ecosystems

Pesticides have a pervasive presence in aquatic ecosystems throughout the world. While pesticides are intended to control fungi, insects, and other pests, their mechanisms of action are often not specific enough to prevent unintended effects, such as on non-target microbial populations. Microorganisms, including algae and cyanobacteria, protozoa, aquatic fungi, and bacteria, form the basis of many food webs and are responsible for crucial aspects of biogeochemical cycling; therefore, the potential for pesticides to alter microbial community structures must be understood to preserve ecosystem services. This review examines studies that focused on direct population-level effects and indirect community-level effects of pesticides on microorganisms. Generally, insecticides, herbicides, and fungicides were found to have adverse direct effects on algal and fungal species. Insecticides and fungicides also had deleterious direct effects in the majority of studies examining protozoa species, although herbicides were found to have inconsistent direct effects on protozoans. Our synthesis revealed mixed or no direct effects on bacterial species among all pesticide categories, with results highly dependent on the target species, chemical, and concentration used in the study. Examination of community-level, indirect effects revealed that all pesticide categories had a tendency to reduce higher trophic levels, thereby diminishing top-down pressures and favoring lower trophic levels. Often, indirect effects exerted greater influence than direct effects. However, few studies have been conducted to specifically address community-level effects of pesticides on microorganisms, and further research is necessary to better understand and predict the net effects of pesticides on ecosystem health.
Ethical Leadership, Work Meaningfulness, and Work Engagement in the Public Sector

This study responds to recent calls for research on how and why ethical leadership is related to employee outcomes. Drawing on self-concept–based theory and substitutes-for-leadership theory, the study examines both the mediating and moderating role of work meaningfulness on the relationship between ethical leadership and work engagement. Using a sample of Egyptian public hospital nurses, the results of structural equation modeling (SEM) revealed that work meaningfulness partially mediated the relationship between ethical leadership and engagement. Furthermore, the results showed the positive relationship between ethical leadership and work engagement was stronger for employees who experienced lower rather than higher levels of meaningfulness. Thus, public sector organizations need to put emphasis on nurturing ethical leadership and stimulating employees’ sense of work meaningfulness. However, they need to be aware that, sometimes, they may not be able to get “double the benefits” when they invest in developing both.
Tumor-specific transcription factor binding to an activator protein-2/Sp1 element of the urokinase-type plasminogen activator receptor promoter in a first large series of resected gastrointestinal cancers.

PURPOSE Evidence for transactivation of genes via specific promoter elements has been derived from studies on tumor cell lines but rarely on resected tumors. However, the proof of an in vivo relevance and the identification of patients with a potential tumor-specific gene expression is essential to transfer molecular-targeting strategies into clinical applications. This study gives the first clinical evidence that urokinase-type plasminogen activator receptor (u-PAR) gene expression is tumor-specifically regulated via an activator protein (AP)-2/Sp1 promoter element in a large patient subpopulation. EXPERIMENTAL DESIGN In 145 gastrointestinal cancer patients, electrophoretic mobility shift analysis and supershift assays for u-PAR-promoter region -152/-135 were performed in tumors and corresponding normal tissues. u-PAR protein levels were measured by ELISA. RESULTS Binding of Sp1 to region -152/-135 in tumors in contrast to corresponding normal mucosae was observed in 55% of colorectal and in 52% of gastric cancer patients. Tumor-specific binding of an AP-2-related factor was seen in 59% of colorectal and in 63% of gastric cancer patients. A significant correlation between AP-2 (P < 0.0001) and Sp1 (P = 0.0003) binding with a high u-PAR expression was observed in tumors but not in normal mucosae. Tissues of five nontumor patients did not show transcription factor binding to this region. CONCLUSIONS This is the first study to show the tumor-specific binding of trans-activators to the u-PAR promoter region (-152/-135) biochemically in a large series of resected tumors. For the subpopulation of approximately 60% of patients with tumor-restricted u-PAR-transactivation, a molecular targeting of this region or its activating pathways should be pursued as a new antimetastasis therapy approach.
Republished paper: Improving safety culture on adult medical units through multidisciplinary teamwork and communication interventions: the TOPS Project

Aim The goal of this project was to improve unit-based safety culture through implementation of a multidisciplinary (pharmacy, nursing, medicine) teamwork and communication intervention. Method The Agency for Healthcare Research and Quality Hospital Survey on Patient Safety Culture was used to determine the impact of the training with a before–after design. Results Surveys were returned from 454 healthcare staff before the training and 368 staff 1 year later. Five of eleven safety culture subscales showed significant improvement. Nurses perceived a stronger safety culture than physicians or pharmacists. Conclusion While it is difficult to isolate the effects of the team training intervention from other events occurring during the year between training and postevaluation, overall the intervention seems to have improved the safety culture on these medical units.
Sickle cell disease: Ischemia and seizures

Although the prevalence of seizures in children with sickle cell disease (SCD) is 10 times that of the general population, there are few prospectively collected data on mechanism. With transcranial Doppler and magnetic resonance imaging (MRI) and angiography, we evaluated 76 patients with sickle cell disease, 29 asymptomatic and 47 with neurological complications (seizures, stroke, transient ischemic attack, learning difficulty, headaches, or abnormal transcranial Doppler), who also underwent bolus‐tracking perfusion MRI. The six patients with recent seizures also had electroencephalography. Group comparisons (seizure, nonseizure, and asymptomatic) indicated that abnormal transcranial Doppler was more common in the seizure (4/6; 67%) and nonseizure (26/41; 63%) groups than in the asymptomatic (10/29; 34%) group (χ2; p = 0.045), but abnormal structural MRI (χ2; p = 0.7) or magnetic resonance angiography (χ2; p = 0.2) were not. Relative decreased cerebral perfusion was found in all seizure patients and in 16 of 32 of the remaining patients with successful perfusion MRI (p = 0.03). In the seizure patients, the perfusion abnormalities in five were ipsilateral to electroencephalographic abnormalities; one had normal electroencephalogram results. These findings suggest that vasculopathy and focal hypoperfusion may be factors in the development of sickle cell disease–associated seizures. Ann Neurol 2005;58:290–302
Atrial fibrillation and bisphosphonate therapy

Bisphosphonates are the most commonly used treatment for osteoporosis and have proven efficacy in the reduction of vertebral and nonvertebral fractures. Recently, concerns have been raised about a possible association between bisphosphonate therapy and atrial fibrillation (AF) following the report of a significant increase in risk of serious AF in women treated with zoledronic acid in the HORIZON study. Subsequent studies have produced conflicting results but have not excluded the possibility of such an association. Currently there is no direct evidence that bisphosphonates exert either acute or chronic effects on cardiac electrophysiology. Nevertheless, altered intracellular electrolyte homeostasis and proinflammatory, profibrotic, and antiangiogenic effects provide potential mechanisms by which atrial conduction could be affected in patients treated with bisphosphonates. In studies in which an increase in risk of AF has been identified, there is no evidence that this translates into increased mortality or increased risk of stroke, and the risk‐benefit balance of bisphosphonate therapy in patients with osteoporosis and other forms of metabolic bone disease remains strongly positive. © 2010 American Society for Bone and Mineral Research
Community Based Programs Sustainability. A Multidimensional Analysis of Sustainability Factors

Ensuring community based program sustainability is critical for the targeted communities. When such a program is no longer sustainable, its impact decreases, leading to unmet expectations, affecting the community as a whole. As such, scrutinizing sustainability factors for community based programs proves essential. This paper analyses those factors by reviewing the literature, questioning 188 individuals from community based organizations and other non-profits and providing a ranking for the most important of them. The factors were divided into 3 categories: related to program itself, related to host (implementing) organisation and related to the community where the program is operationalized. For data analysis several statistical tests were used, leading to a ranking of the most important 22 factors for community based programs sustainability.
The Power of Prestige: Explaining China’s Nuclear Weapons Decisions

ABSTRACT The majority of the nuclear proliferation literature is dedicated to understanding why states acquire nuclear weapons. While this question remains important, it is also advantageous to push beyond this inquiry to ask what motivates a state’s nuclear decisions after acquisition. Recent research indicates that a state’s nuclear force structure is heavily influenced by its threat environment. But what explains decisions relating to specific nuclear weapon systems? If security is a sufficient explanatory variable, then why would a state pursue nuclear weapons with high development and production costs but relatively low security gains? Using China as a case study, this article explores the power of prestige in explaining such decisions.
Cutting Edge: NKG2ChiCD57+ NK Cells Respond Specifically to Acute Infection with Cytomegalovirus and Not Epstein–Barr Virus

CMV induces the expansion of a unique subset of human NK cells expressing high levels of the activating CD94-NKG2C receptor that persist after control of the infection. We investigated whether this subset is CMV specific or is also responsive to acute infection with EBV. We describe a longitudinal study of CMV− and CMV+ students who were acutely infected with EBV. The NKG2Chi NK subset was not expanded by EBV infection. However, EBV infection caused a decrease in the absolute number of immature CD56brightCD16− NK cells in the blood and, in CMV+ individuals, induced an increased frequency of mature CD56dimNKG2A+CD57+ NK cells in the blood that persisted into latency. These results provide further evidence that NKG2C+ NK cells are CMV specific and suggest that EBV infection alters the repertoire of NK cells in the blood.
Determinants of moonlighting in the European Parliament

ABSTRACT In recent years, several national parliaments have introduced stricter rules for the disclosure of additional sources of income earned by their legislators. In this context of better data availability, the phenomenon of ‘moonlighting’ politicians (legislators who pursue paid or unpaid jobs next to their political mandate) has attracted increased public and scientific attention. Since 2011, the European Parliament (EP) has required its parliamentarians (MEPs) to make their additional earnings public if they exceed a certain threshold. So far, however, the determinants of varying numbers of outside jobs and associated ancillary income have not been analysed for the EP. The authors seek to fill this lacuna by building upon a new data set of moonlighting activities for all MEPs holding a mandate during the seventh term of the institution (2009–2014). Specifically, the authors assess the extent to which individual-level factors such as gender, ideology, experience and education help to account for varying degrees of moonlighting among MEPs and whether national-level factors such as economic development and electoral systems play a role. The findings suggest that moonlighting is particularly prevalent among MEPs from conservative and liberal groups, while the level of outside income that MEPs accrue is additionally related to gender and education.
Rethinking Youth Civic Engagement and Political Participation in Zimbabwe

This article explores power shifts in Zimbabwe post November 2017’s military assisted transition and its bearing on youth engagement in civic and political participation. The article further discusses youth engagement and participation as crucial in a country that has a significantly high youth population which has been disfranchised by political upheavals that have resulted in a polarised society with multiple socio-economic challenges. The article shares interventions that can be appropriate in scaling up youth agency in the making of a new political culture for Zimbabwe. Although political continuities such as intimidation and unabated state control of the public media are visible, there are also emerging opportunities for improved youth participation in civic and political processes such as creation of new spaces for youth engagement and renewed interest in political participation amongst youth both as candidates and voters. Acknowledging that Zimbabwe stands in a space where it can either consolidate the role of the youth or further obscure them from political participation, the article makes submissions on how the emerging political culture where youth are taking centre stage can be sustained if focus is given on issues rather than partisan interests.

HLA-DQB1*02–Restricted HPV-16 E7 Peptide–Specific CD4+ T-Cell Immune Responses Correlate with Regression of HPV-16–Associated High-Grade Squamous Intraepithelial Lesions

Purpose: The fact that up to 30% of established high-grade squamous intraepithelial lesions (HSIL) of the cervix regress spontaneously presents the opportunity to identify clinically relevant human papillomavirus (HPV) viral epitopes associated with disease outcome. Two human HPV antigens, E6 and E7, are functionally required for initiation and maintenance of cervical cancer precursor lesions and invasive cervical cancer. The identification and characterization of endogenously processed HPV antigenic epitopes in closely characterized patient cohorts will provide insight into the reasons for success or failure of therapeutic approaches. Experimental Design: We characterized the HPV-16 E6/E7–specific T-cell epitopes using E6/E7 overlapping peptide pools with peripheral blood lymphocytes obtained from normal healthy donors. We then analyzed the difference in the HPV-16 T-cell immune responses in HPV-16+ HSIL patients with or without spontaneous regression of lesions using the statistical methods. Results: We have identified an HPV-16 E7–specific CD4+ T-cell epitope [amino acids (aa) 71-85] that was restricted by HLA-DQB1*0201. Analysis of peripheral blood lymphocytes obtained from 14 HLA-DQB1*02 patients with HPV-16+ HSILs showed that the HPV-16+ E7 peptide (aa 71-85)–specific CD4+ T-cell immune response was significantly higher in the group of patients with regression compared with the patients without regression (P value <0.05). Conclusions: The HPV-16 E7 peptide–specific CD4+ T-cell immune response correlates with spontaneous regression of established HPV16+ HSILs. Thus, this E7 epitope may be useful for the characterization of HPV-specific immune responses in patients infected with HPV-16 or immunized with HPV vaccines.
Diagnostic characteristics of 93 cases of a prepubertal and early adolescent bipolar disorder phenotype by gender, puberty and comorbid attention deficit hyperactivity disorder.

OBJECTIVE Etiopathogenetic and treatment studies require homogeneous phenotypes. Therefore, effects of gender, puberty, and comorbid attention deficit hyperactivity disorder (ADHD) on DSM-IV mania criteria and other characteristics of a prepubertal and early adolescent bipolar disorder (PEA-BP) phenotype were investigated. METHOD Consecutively ascertained PEA-BP (with or without comorbid ADHD) outpatients (n = 93) were blindly assessed by research nurses with comprehensive instruments given to mothers and children separately, consensus conferences, and offsite blind best estimates of both diagnoses and mania items. To fit the study phenotype, subjects needed to have current DSM-IV mania or hypomania with elated mood and/or grandiosity as one criterion and to be definite cases by severity ratings. RESULTS Subjects were aged 10.9 +/- 2.6 years, had current episode length of 3.6 +/- 2.5 years, and had early age of onset at 7.3 +/- 3.5 years. No significant differences were found by gender, puberty, or comorbid ADHD on rates of mania criteria (e.g., elation, grandiosity, racing thoughts), mixed mania, psychosis, rapid cycling, suicidality, or comorbid oppositional defiant disorder (ODD), with few exceptions. Subjects with comorbid ADHD were more likely to be younger and male. Pubertal subjects had higher rates of hypersexuality. CONCLUSIONS These findings support that the PEA-BP phenotype is homogeneous except for differences (hyperactivity, hypersexuality) that mirror normal development.
Histology and immunohistochemistry study of ovine tendon grafted with cBMSCs and BMMNCs after collagenase-induced tendinitis

Summary Objectives: The aim of this study was to compare the regeneration abilities of cultured bone marrow mesenchymal cells (cBMSC) and bone marrow mononuclear cells (BMMNC) with fibrin glue, saline solution and sham control in collagenase–induced tendinitis of the Achilles tendon in sheep. Methods: Six sheep were recruited randomly to each group: cBMSC, BMMNC, fibrin, saline and sham control. Each group received the relative treatment two weeks after inducing lesions (T0). After eight weeks (T8) of treatment, the tendons were harvested and evaluated for histomorphology, Collagen type I, III, Cartilage Oligomeric Matrix Protein (COMP) and CD34 positive cells expression. Results: Histology and immunohistochemistry showed similar capabilities of cBMSC and BMMNC to restore the architecture of fibres and Extra Cellular Matrix (ECM), with a high expression of collagen type I and COMP and a very low expression of collagen type III in treated tendons. The complete architectural disruption of fibres, dramatic reduction of collagen Type I and COMP expression and increase collagen type III expression were commonly observed in tendons treated with fibrin or saline only. The presence of CD34 positive cells was appreciable in the BMMNC group while few cBMSC showed this cluster of differentiation, not expressed in tendons treated with fibrin or saline. Clinical significance: The data in this study show the efficacy of cBMSC and BMMNC in regenerating tendon tissue after collagenase–induced tendinitis.
