Importance of the f protein in the immunity of the newcastle disease viruS.
Monoclonal antibodies directed against HN and F, the two surface glycoproteins of Newcastle disease virus were prepared and characterized using hemagglutination inhibition, séroneutralisation and radio-immunoprecipitation tests.
The relative importance of HN and F antibodies in the immunity against Newcastle disease virus was estimated «in vitro» by séroneutralisation and «in vivo» by passive immunisation of SPF chickens.
Monoclonal antibodies directed against the F protein are more potent in passive immunisation tests than HN antibodies ; moreover, they neutralize all representative strains of the different subgroups of Newcastle disease virus.
A recombinant vaccinia virus expressing the F protein of Newcastle disease virus was obtained by genetic engineering. Preliminary vaccination results using this recombinant demonstrate the potential interest of the use of Newcastle disease vaccines based on the F protein.

Published: January 2018

Les auteurs décrivent un foyer de septicémie à pneumocoques (Streptococcus pneumoniae) chez des veaux en France. L’affection sévit chez des animaux très jeunes de 0 à 8 semaines jusqu’à 3 mois et est d’évolution très rapide (quelques heures) accompagnée d’entérite subaiguë, et de lésions pulmonaires diffuses.
Cette maladie peut être confondue avec de la colibacillose ou de la salmonellose ; seuls les examens bactériologiques permettent le diagnostic.
C’est une affection bien connue en Allemagne, Danemark, Suisse, présente aussi en Italie et en Angleterre. En France, la maladie existe mais l’évolution est telle que les différentes phases de son diagnostic sont difficiles. Le sérotype de Streptococcus pneumoniae trouvé dans cette étude est un 18, sérotype assez fréquent en médecine humaine.
Evolution de la théorie fromagère et utilisation de la glucono-delta-lactone
Authors: Labié Jacques 
Published: January 2018

Le manque de connaissance concernant la formation et l’évolution de la porosité du caillé en fromagerie, explique principalement l’importance de l’empirisme dans ce secteur de l’agro-alimentaire.
De récents travaux scientifiques ont fait évoluer les conceptions technologiques : les deux types de caillé obtenu par voie enzymatique ou par voie acide ont, tout au moins au début de l’égouttage, une perméabilité très peu différente l’un de l’autre et la fabrication fromagère peut être considérée comme un phénomène d’agglomération correspondant à une synérèse, associé à un phénomène d’écoulement.
L’agglomération, qui est plus rapide s’il y a eu action de la présure, ne peut se poursuivre sans découpage du coagulum.
La glucono-delta-lactone, en libérant lentement et de manière continue de l’acide gluconique à une dose précise, permet de mieux maîtriser le pH à la coagulation et répond ainsi à un besoin de l’industrie fromagère française, par suite de modifications des caractéristiques du lait résultant de nouvelles techniques de production et de collecte. Le rendement est amélioré.

Experimental infection with Mycoplasma gallisepticum in chickens, turkeys, laying hens and cluck embryos.
The Mycoplasma gallisepticum R strain is serially passaged ten times through specific pathogen free (SPF) chickens in order to exacerbate its potential pathogenicity. The recovered MGR P10 strain is inoculated in SPF chickens and turkeys, commercial laying fowl and nineteen-day-old chick embryos. The inoculation induces general and respiratory symptoms in the different hosts. Mortality occurs in the chicks hatched from inoculated embryos. A drop in egg production is observed in the laying hens. The strain is also shown to be able to spread from bird to bird.

Deux rapports et un vœu récents du P.E. semblent introduire deux faits nouveaux, en matière d'A.M.M. de produits de santé animale.
Pour certains d'entre eux, des critères nouveaux devront être satisfaits afin de permettre la constitution de dossiers complets.
A côté des trois critères classiques (qualité, sécurité, efficacité), interviendra un soi-disant «quatrième critère», qui en comportera en réalité six.
Des questions se posent sur les conséquences de ce «quatrième critère» en matière de recherche et de développement, des produits de santé animale, et en particulier de leur coût.
An adaptive two-stage analog/regression model for probabilistic prediction of small-scale precipitation in France
Authors: Chardon Jérémy , Hingray Benoit , Favre Anne-Catherine 
Published: January 2018

Abstract. Statistical downscaling models (SDMs) are often used to produce local weather scenarios from large-scale atmospheric information. SDMs include transfer functions which are based on a statistical link identified from observations between local weather and a set of large-scale predictors. As physical processes driving surface weather vary in time, the most relevant predictors and the regression link are likely to vary in time too. This is well known for precipitation for instance and the link is thus often estimated after some seasonal stratification of the data. In this study, we present a two-stage analog/regression model where the regression link is estimated from atmospheric analogs of the current prediction day. Atmospheric analogs are identified from fields of geopotential heights at 1000 and 500 hPa. For the regression stage, two generalized linear models are further used to model the probability of precipitation occurrence and the distribution of non-zero precipitation amounts, respectively. The two-stage model is evaluated for the probabilistic prediction of small-scale precipitation over France. It noticeably improves the skill of the prediction for both precipitation occurrence and amount. As the analog days vary from one prediction day to another, the atmospheric predictors selected in the regression stage and the value of the corresponding regression coefficients can vary from one prediction day to another. The model allows thus for a day-to-day adaptive and tailored downscaling. It can also reveal specific predictors for peculiar and non-frequent weather configurations.

Defining the Key Parts of a Procedure: Implications for Overlapping Surgery
Authors: Bernstein Joseph , Bernstein James J. , Mehta Samir , Hume Eric L. , Schenker Mara L. , Ahn Jaimo 
Published: January 2018

Introduction:
The American College of Surgeons’ Statements on Principles requires attending surgeons to be present for the “key parts” of surgical procedures, but the term is not defined. The research question addressed in this study is whether a functional definition of the critical or key steps of common orthopaedic surgical procedures can be reliably constructed. We used the examples of hip and knee arthroplasty because these procedures are highly structured and divisible into distinct subroutines.

Methods:
We surveyed 100 experienced orthopaedic surgeons regarding whether particular steps in knee and hip arthroplasty procedures were considered “key.” The patterns of individual surgeons’ responses were compared among surgeons for overall reliability. The steps frequently cited as key were also identified.

Results:
The agreement rates among surgeons for the definitions of the key parts of hip and knee arthroplasty were 3.2% and 8.6%, respectively. For both procedures, five steps were identified as key by >90% of the respondents.

Discussion:
The agreement rate on what constitutes the key parts of hip and knee arthroplasty was poor, despite the fact that these are highly structured procedures. Accordingly, defining the key parts for a given procedure must rely on either the operating surgeon’s discretion or a consensus definition. Imposing a single surgeon’s standard on others is not the optimal approach because such a standard is likely to be idiosyncratic.

Conclusion:
A consensus standard articulated by the orthopaedic surgery community may be the best means for identifying the key parts of orthopaedic surgical operations. The data presented here suggest a foundation upon which a consensus definition for the key parts of arthroplasty procedures may be built.
