A scanning electron-microscope examination of the scolex of Houttuynia struthionis

A scanning electron-microscope examination of the scolex of Houttuynia struthionis, a cestode of ostriches, was undertaken in order to study its surface structure. The scolex differs from those of other subfamilies in the family Davaineidae in that it does not have scale-like spines covering the base of the rostellum. Instead, the base is covered with small hooks resembling the larger rostellar hooks in shape.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Effect of summer grazing on welfare of dairy cows reared in mountain tie-stall barns

Traditional mountain farms have an important economic, social and environmental role. The Alps management system for dairy cows consists of animals kept indoors from autumn to spring, mostly in tie-stalls, and moved to mountain pasture in summer. The aim of our study was to assess the effect of mountain summer grazing on the welfare of dairy cows housed in tie-stall barns. Twenty-four farms were considered. In twelve of them, animals were reared in tie-stalls and moved to mountain pasture for three months in summer; they were visited three times: (i) four weeks before grazing during the indoor period in the stall; (ii) about three weeks after the start of grazing; and (iii) in the stall, in autumn, at least three weeks after returning from grazing. The other twelve farms kept the animals in tie-stalls all year; they were visited once in autumn. Data were collected following a protocol that considers animal-based measures and structure information on the basis of Quality Welfare Consortium® indications. Data allowed the calculation of both the Animal Needs Index score (ANI 35L) and an overall assessment of the cows' welfare obtained from three general aspects: housing, animal's physical condition, and animal's behaviour. Summer grazing had a significant positive effect on injuries, lameness and animal's rising duration but a negative effect on faeces consistency. Moreover, a reduction of tongue playing was observed. The ANI 35L and the overall assessment did not show significant differences linked to summer grazing, which tended to have a positive but temporary effect on animal behaviour

Being (im)polite: A forensic linguistic approach to interpreting a hate speech case

In a hate speech case a court might have to determine whether a person’s words were hurtful or harmful. Would it be possible to determine whether words are hurtful or harmful by using linguistics? This article offers a linguistic perspective on a court’s interpretation of the Equality Act in a hate speech case and focuses on speech acts and politeness. If the speech acts of a verbal exchange are studied and the levels of politeness are gauged, a court would be able to affi rm the hurtfulness or harmfulness of the speaker’s words. The article begins with a brief discussion on the potential role of the linguist in a courtroom; this is followed by a summary of the facts of the case. Then the court case is analysed and discussed in terms of speech acts and politeness. By employing principles in pragmatics the author reaches the same conclusion as the court.Afrikaans and Theory of Literatur

Efeito do genótipo e da idade de ovinos na reatividade medida em pista de venda

Objetivou-se avaliar o comportamento de ovinos e relacionar aspectos comportamentais com a raça e idade dos animais. Foram observados 5.971 animais divididos em 181 lotes quanto às raças – Corriedale (n = 2.731), Ideal (n = 1.574), Merino (n = 168), Texel (n = 717), Suffolk (n = 247) e 6 mestiços (n = 534) – e quanto à idade – cordeiras (1,5 ano, n = 3.021), ovelhas (acima de 1,5 ano, n = 2457) e cordeiras dente-de-leite (média de 6 meses de idade, n = 493). O comportamento médio dos lotes foi avaliado pela atribuição de escores de movimentação e resistência à condução na entrada, permanência e saída da pista de comercialização. Os animais das raças mais especializadas para produção de carne (Suffolk e Texel) e os animais jovens foram os mais agitados e apresentaram maior resistência à condução pelo homem em comparação àqueles das raças produtoras de lã e aos mais velhos. Os escores comportamentais foram positivamente relacionados entre si, o que permite a escolha de qualquer um deles para medir o comportamento dos ovinos. O comportamento de ovinos em pista de venda é influenciado pela idade e raça.The objective of this work was to evaluate behavior of sheep and to relate behavioral aspects with breed and age of animals. It was observed 5,971 animals distributed in 181 plots regarded to: breed - Corriedale (n=2,731), Ideal (n=1,574), Merino (n=168), Texel (n=717), Suffolk (n=247) and six crossbreds (n=534); age - yearlings (1.5 year, n=3,021), ewes (above 1.5 year, n =2,457) and lambs (average 6 months of age, n=493). Average behavior of plots was evaluated by attributing scores of movement and resistance to conduction at entrance, permanence and exit from the market auction. Animals from more specialized breeds for meat production (Sulfock and Texel) and young animals were the most agitated and they showed more resistance to human conduction compared to those wool producer breeds and to the older ones. Behavior scores positively correlated among each other, allowing to choose any of them to measure sheep behavior. Sheep on market auction behavior is influenced by age and breed

Improving Genetic Prediction by Leveraging Genetic Correlations Among Human Diseases and Traits

Genomic prediction has the potential to contribute to precision medicine. However, to date, the utility of such predictors is limited due to low accuracy for most traits. Here theory and simulation study are used to demonstrate that widespread pleiotropy among phenotypes can be utilised to improve genomic risk prediction. We show how a genetic predictor can be created as a weighted index that combines published genome-wide association study (GWAS) summary statistics across many different traits. We apply this framework to predict risk of schizophrenia and bipolar disorder in the Psychiatric Genomics consortium data, finding substantial heterogeneity in prediction accuracy increases across cohorts. For six additional phenotypes in the UK Biobank data, we find increases in prediction accuracy ranging from 0.7 for height to 47 for type 2 diabetes, when using a multi-trait predictor that combines published summary statistics from multiple traits, as compared to a predictor based only on one trait. © 2018 The Author(s)

Genome-wide association study identifies 30 Loci Associated with Bipolar Disorder

This paper is dedicated to the memory of Psychiatric Genomics Consortium (PGC) founding member and Bipolar disorder working group co-chair Pamela Sklar. We thank the participants who donated their time, experiences and DNA to this research, and to the clinical and scientific teams that worked with them. We are deeply indebted to the investigators who comprise the PGC. The views expressed are those of the authors and not necessarily those of any funding or regulatory body. Analyses were carried out on the NL Genetic Cluster Computer (http://www.geneticcluster.org ) hosted by SURFsara, and the Mount Sinai high performance computing cluster (http://hpc.mssm.edu).Bipolar disorder is a highly heritable psychiatric disorder. We performed a genome-wide association study including 20,352 cases and 31,358 controls of European descent, with follow-up analysis of 822 variants with P<1x10-4 in an additional 9,412 cases and 137,760 controls. Eight of the 19 variants that were genome-wide significant (GWS, p < 5x10-8) in the discovery GWAS were not GWS in the combined analysis, consistent with small effect sizes and limited power but also with genetic heterogeneity. In the combined analysis 30 loci were GWS including 20 novel loci. The significant loci contain genes encoding ion channels, neurotransmitter transporters and synaptic components. Pathway analysis revealed nine significantly enriched gene-sets including regulation of insulin secretion and endocannabinoid signaling. BDI is strongly genetically correlated with schizophrenia, driven by psychosis, whereas BDII is more strongly correlated with major depressive disorder. These findings address key clinical questions and provide potential new biological mechanisms for BD.This work was funded in part by the Brain and Behavior Research Foundation, Stanley Medical Research Institute, University of Michigan, Pritzker Neuropsychiatric Disorders Research Fund L.L.C., Marriot Foundation and the Mayo Clinic Center for Individualized Medicine, the NIMH Intramural Research Program; Canadian Institutes of Health Research; the UK Maudsley NHS Foundation Trust, NIHR, NRS, MRC, Wellcome Trust; European Research Council; German Ministry for Education and Research, German Research Foundation IZKF of Münster, Deutsche Forschungsgemeinschaft, ImmunoSensation, the Dr. Lisa-Oehler Foundation, University of Bonn; the Swiss National Science Foundation; French Foundation FondaMental and ANR; Spanish Ministerio de Economía, CIBERSAM, Industria y Competitividad, European Regional Development Fund (ERDF), Generalitat de Catalunya, EU Horizon 2020 Research and Innovation Programme; BBMRI-NL; South-East Norway Regional Health Authority and Mrs. Throne-Holst; Swedish Research Council, Stockholm County Council, Söderström Foundation; Lundbeck Foundation, Aarhus University; Australia NHMRC, NSW Ministry of Health, Janette M O'Neil and Betty C Lynch
