Diagnosis and therapy of retained fetal membranes, puerperal metritis and clinical endometritis in cattle: Results of the Online-survey among Swiss practitioners. II. Puerperal metritis and clinical endometritis

The aim of the study was to obtain the diagnostic and therapeutic approach among Swiss practitioners in cows with puerperal metritis and clinical endometritis (part 2). All members of the Association for ruminant health were contacted per email via the newsletter. The survey was completed by 128 veterinarians, partially responded by 140 veterinarians. The following main symptoms of puerperal metritis were stated by the practitioners: purulent vaginal discharge, fever and reduced appetite. A vaginal and rectal examination was performed to diagnose the disease. Usually, an intrauterine treatment with tetracycline or cefapirin was done. Parenteral administration of tetracycline or penicillin was often combined with PGF(2α), NSAIDS or cortisone. Clinical endometritis was also diagnosed by vaginal and rectal examination and the main symptom indicated was purulent vaginal discharge. The therapy consisted of the administration of PGF(2α), uterine infusions predominantly with cefapirin, and rarely with parenteral administration of antibiotics. Further diagnostic tools were not used and normally cows were not rechecked. The success of the therapy of puerperal metritis and clinical endometritis was judged to be satisfactory to excellent.

Is there an age cutoff to apply adult formulas for GFR estimation in children?

BACKGROUND Estimation of glomerular filtration rate (eGFR) using a common formula for both adult and pediatric populations is challenging. Using inulin clearances (iGFRs), this study aims to investigate the existence of a precise age cutoff beyond which the Modification of Diet in Renal Disease (MDRD), the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), or the Cockroft-Gault (CG) formulas, can be applied with acceptable precision. Performance of the new Schwartz formula according to age is also evaluated. METHOD We compared 503 iGFRs for 503 children aged between 33 months and 18 years to eGFRs. To define the most precise age cutoff value for each formula, a circular binary segmentation method analyzing the formulas' bias values according to the children's ages was performed. Bias was defined by the difference between iGFRs and eGFRs. To validate the identified cutoff, 30% accuracy was calculated. RESULTS For MDRD, CKD-EPI and CG, the best age cutoff was ≥14.3, ≥14.2 and ≤10.8 years, respectively. The lowest mean bias and highest accuracy were -17.11 and 64.7% for MDRD, 27.4 and 51% for CKD-EPI, and 8.31 and 77.2% for CG. The Schwartz formula showed the best performance below the age of 10.9 years. CONCLUSION For the MDRD and CKD-EPI formulas, the mean bias values decreased with increasing child age and these formulas were more accurate beyond an age cutoff of 14.3 and 14.2 years, respectively. For the CG and Schwartz formulas, the lowest mean bias values and the best accuracies were below an age cutoff of 10.8 and 10.9 years, respectively. Nevertheless, the accuracies of the formulas were still below the National Kidney Foundation Kidney Disease Outcomes Quality Initiative target to be validated in these age groups and, therefore, none of these formulas can be used to estimate GFR in children and adolescent populations.

The SOLUTIONS project: challenges and responses for present and future emerging pollutants in land and water resources management.

SOLUTIONS (2013 to 2018) is a European Union Seventh Framework Programme Project (EU-FP7). The project aims to deliver a conceptual framework to support the evidence-based development of environmental policies with regard to water quality. SOLUTIONS will develop the tools for the identification, prioritisation and assessment of those water contaminants that may pose a risk to ecosystems and human health. To this end, a new generation of chemical and effect-based monitoring tools is developed and integrated with a full set of exposure, effect and risk assessment models. SOLUTIONS attempts to address legacy, present and future contamination by integrating monitoring and modelling based approaches with scenarios on future developments in society, economy and technology and thus in contamination. The project follows a solutions-oriented approach by addressing major problems of water and chemicals management and by assessing abatement options. SOLUTIONS takes advantage of the access to the infrastructure necessary to investigate the large basins of the Danube and Rhine as well as relevant Mediterranean basins as case studies, and puts major efforts on stakeholder dialogue and support. Particularly, the EU Water Framework Directive (WFD) Common Implementation Strategy (CIS) working groups, International River Commissions, and water works associations are directly supported with consistent guidance for the early detection, identification, prioritisation, and abatement of chemicals in the water cycle. SOLUTIONS will give a specific emphasis on concepts and tools for the impact and risk assessment of complex mixtures of emerging pollutants, their metabolites and transformation products. Analytical and effect-based screening tools will be applied together with ecological assessment tools for the identification of toxicants and their impacts. The SOLUTIONS approach is expected to provide transparent and evidence-based candidates or River Basin Specific Pollutants in the case study basins and to assist future review of priority pollutants under the WFD as well as potential abatement options.

Development and characterization of novel microsatellite markers for Arion slug species

Seventeen polymorphic microsatellite markers were isolated and characterized in Arion vulgaris/lusitanicus, which belongs to the worst European slug pests with serious economic and ecological impact. These markers were tested on 23 individuals collected in a population in Switzerland. Numbers of alleles ranged from 2 to 14 per locus, observed and expected heterozygosities ranged from 0.174 to 0.87, and from 0.162 to 0.903, respectively. These loci were also successfully amplified and were polymorphic in the closely related species A. rufus and A. ater. These loci represent the first highly polymorphic nuclear markers described for A. vulgaris and pave the way for population genetics and molecular ecology research of the important Arion pest slugs.

Inflammatory Airway Disease of Horses-Revised Consensus Statement

The purpose of this manuscript is to revise and update the previous consensus statement on inflammatory airway disease (IAD) in horses. Since 2007, a large number of scientific articles have been published on the topic and these new findings have led to a significant evolution of our understanding of IAD.

Implications of Longterm Diameter-Limit Harvesting: Effects on Radial Growth of Red Spruce (Picea rubens) and Genetic Diversity of White Pine (Pinus strobus)

For over 3 centuries, diameter-limit harvesting has been a predominant logging method in the northeastern United States. Silvicultural theory asserts that such intensively selective harvesting can lead to genetic degradation. A decrease in softwood productivity has recently been reported in Maine - has a long history of dysgenic selection degraded the genetic resources of Maine softwoods, contributing to a decrease in growth and productivity? This study examines two aspects of potential implications of diameter-limit harvesting: effects on residual phenotypes of red spruce and impacts on genetic diversity of white pine. Radial growth of residual red spruce trees in stands experiencing 50 years of fixed diameter-limit harvesting was measured using annual increment rings and compared with residual red spruce trees in positive selection stands. Trees remaiaing after several rounds of diameter-limit harvesting exhibited sigdicantl y smaller radial sizes throughout their lives, and displayed significantly slower growth rates for the first 80 years of measured growth. These results strongly suggest that the largest and fastest-growing genotypes and their respective gene complexes determining good radial growth have been removed from the diameter-limit stand. Dysgenic selection can be observed in fixed diarneter-limit stands, resulting in a diminished genetic resource and decreased residual stand value. To examine more direct genetic implications of long-term diameter-limit harvesting, microsatellite DNA markers were implemented to study genetic diversity of eastern white pine in Maine. Three age groups of trees were studied: mature trees older than 200 years, juvenile trees 5-30 years old, and embryos. Trees were genotyped at 10 microsatellite loci. Overall genetic diversity levels of eastern white pine in Maine were extremely high, with an average observed heterozygosity of 0.762. Genetic differentiation was minimal among and between all three age groups, although an excess of heterozygotes was shown in the mature and juvenile groups that was not reflected in the embryo group, which actually had a slight heterozygote deficiency. Allele frequencies did not differ significantly between age groups, but did reveal more rare and low frequency alleles in the embryo groups than in the mature group. Overall, low frequency alleles comprise the largest portion of alleles in the sample population, with no common alleles evident overall. These results suggest that significant genetic degradation has either not occurred for white pine, or that the results of dysgenic selection have not yet emerged. It is clear, however, that selective harvesting could result in a loss of low frequency alleles, which are a primary reserve of evolutionary potential in a species. Implications of these studies affect industrial forestry, regional economics, and ecological concerns for the northeast. Long-term diameter-limit harvesting can lead to a degradation of residual phenotypes, and an overall decrease in stand quality. Potentially, a loss of low frequency, locally adapted alleles could result in a decrease of allelic richness and degradation of the regidnal genetic resource. Decreased genetic variation can lead to seriously limited evolutionary potential of species and ecosystems, particularly in rapidly changing environments. Based on these findings, I recommend a reassessment of any harvesting prescription that includes fixed diameter-limit removals, particularly for species that have low natural genetic diversity levels or a limited natural range, such as red spruce. Maintenance of a healthy genetic reserve can avoid effects of dysgenic harvesting.

Signal transduction of CEACAM1-L tumor suppressor

CEACAM1-L is an adhesion molecule that suppress the growth of prostate, breast, colon and endometrial tumors. In this study we defined the domain involved in CEACAM1-L tumor suppression activity. DU145 prostate cancer cells were infected with recombinant adenoviruses containing various CEACAM1-L mutant genes, and the effects of the mutant proteins on the growth of DU145 cells were assessed in a nude-mice xenograft model. We found that expression of the CEACAM1-L cytoplasm domain alone led to growth suppression of DU145 cells. These results suggest that the cytoplasmic domain of CEACAM1-L is necessary and sufficient for its growth-suppressive function. ^ The cytoplasmic domain of CEACAM1-L is presumed to be involved in a signaling pathway resulting in the suppression of tumor cell growth. It was not clear whether post-translational modification of CEACAM1-L is required for tumor suppressor function, therefore the importance of phosphorylation in growth-inhibitory signaling pathway was investigated. Full-length CEACAM1-L was found to be phosphorylated in vivo in both tyrosine and serine residues. Mutation of tyrosine 488 to phenylalanine did not abolish the tumor-suppressive activity of CEACAM1-L while mutation of serine 503 to alanine abolished the growth-inhibitory activity. In addition, mutation of serine 503 to aspartic acid produced tumor-suppressive activity similar to that of the wild-type CEACAM1-L. These results suggested that only phosphorylation at serine 503 is essential for CEACAM1-L's growth-inhibitory function in vivo. ^ Phosphorylation of CEACAM1-L may lead to its interaction with molecules in CEACAM1-L's signaling pathway. In the last part of this study we demonstrate that CEACAM1 is able to interact with the adapter protein p66Shc. p66Shc was found to be co-immunoprecipitated with full length CEACAM1-L but not with CEACAM1-L lacking its cytoplasmic tail. Additionally this interaction occurred in the absence of the tyrosine phosphorylation of CEACAM1-L. These results suggest that p66Shc is able to interact with the cytoplasmic domain of CEACAM1-L and this interaction does not require tyrosine phosphorylation. ^ In conclusion, this study suggests that CEACAM1-L signals tumor suppression through its cytoplasmic domain by initially becoming phosphorylated on serine 503. Additionally, the interaction with p66Shc may be involved in CEACAM1-L's signaling pathway. ^

NFkappaB and STAT binding elements participate in regulation of MUC1 expression in normal and transformed mammary epithelial cells

The MUC1 gene encodes a transmembrane mucin glycoprotein that is overexpressed in several cancers of epithelial origin, including those of breast, pancreas, lung, ovary, and colon. Functions of MUC1 include protection of mucosal epithelium, modulation of cellular adhesion, and signal transduction. Aberrantly increased expression of MUC1 in cancer cells promotes tumor progression through adaptation of these functions. Some regulatory elements participating in MUC1 transcription have been described, but the mechanisms responsible for overexpression are largely unknown. A region of MUC1 5′ flanking sequence containing two conserved potential cytokine response elements, an NFκB site at −589/−580 and a STAT binding element (SBE) at −503/−495, has been implicated in high level expression in breast and pancreatic cancer cell lines. Persistent stimulation by proinflammatory cytokines may contribute to increased MUC1 transcription by tumor cells. ^ T47D breast cancer cells and normal human mammary epithelial cells (HMEC) were used to determine the roles of the κB site and SBE in basal and stimulated expression of MUC1. Treatment of T47D cells and HMEC with interferon-γ (IFNγ) alone enhanced MUC1 expression at the level of transcription, and the effect of IFNγ was further stimulated by tumor necrosis factor-α (TNFα). MUC1 responsiveness to these cytokines was modest in T47D cells but clearly evident in HMEC. Transient transfection of T47D cells with mutant MUC1 promoter constructs revealed that the κB site at −589/−580 and the SBE at −503/−495 and were required for cooperative stimulation by TNFα and IFNγ. Electrophoretic mobility shift assays (EMSA) revealed that the synergy was mediated not by cooperative binding of transcription factors but by the independent actions of STAT1α and NFκB p65 on their respective binding sites. Independent mutations in the κB site and SBE abrogated cytokine responsiveness and reduced basal MUC1 promoter activity by 45–50%. However, only the κB site appeared to be constitutively activated in T47D cells, in part by NFκB p65. These findings implicate two cytokine response elements in the 5 ′ flanking region of MUC1, specifically a κB site and a STAT binding element, in overexpression of MUC1 in breast cancer cells. ^
