The sf32 unique gene of Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV) is a non-essential gene that could be involved in nucleocapsid o…

2013

A recombinant virus lacking the sf32 gene (Sf32null), unique to the Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV), was generated by homologous recombination from a bacmid comprising the complete viral genome (Sfbac). Transcriptional analysis revealed that sf32 is an early gene. Occlusion bodies (OBs) of Sf32null contained 62% more genomic DNA than viruses containing the sf32 gene, Sfbac and Sf32null-repair, although Sf32null DNA was three-fold less infective when injected in vivo. Sf32null OBs were 18% larger in diameter and contained 17% more nucleocapsids within ODVs than those of Sfbac. No significant differences were detected in OB pathogenicity (50% lethal concentration)…

Predictions of avian Plasmodium expansion under climate change.

2013

International audience; Vector-borne diseases are particularly responsive to changing environmental conditions. Diurnal temperature variation has been identified as a particularly important factor for the development of malaria parasites within vectors. Here, we conducted a survey across France, screening populations of the house sparrow (Passer domesticus) for malaria (Plasmodium relictum). We investigated whether variation in remotely-sensed environmental variables accounted for the spatial variation observed in prevalence and parasitemia. While prevalence was highly correlated to diurnal temperature range and other measures of temperature variation, environmental conditions could not pre…

Closed-loop bandwidth impact on MVSA for rotor broken bar diagnosis in IRFOC double squirrel cage induction motor drives

2013

This paper investigates the detectability of rotor broken bars in indirect rotor flux oriented control (IRFOC) for variable speed double cage induction motor drives, using vibration signature analysis techniques. The Impact of the closed loop control system cannot be neglected when the detection of rotor asymmetries in the machine is based on the signature analysis of electrical or mechanical variables. Therefore, the investigation of rotor fault components for different bandwidths of closed-loop regulators is necessary to evaluate its relevance in the above listed variables. This paper investigates the impact of the control system on relevance of the fault components computed from axial an…

Quittor, an obsolete disease

2012

Quittor was a disease of the pastern and crown area of the ungulates. It was quite common in the horse until the early twentieth century. It was characterized by necrosis manifested by a mass, outward symptom of a phlegmon, which ulcerated and expelled necrotic tissue. The hippiatric healers and early veterinarians generally recognized four forms, the most dangerous was the necrosis of fibrocartilages of the foot. Treatment involved excision of the latter which involved a spectacular operating manual. This action marked the beginning of the veterinary profession, until the disappearance of the disease that was a result of the mechanization of agriculture and transport. It is now very uncomm…

Microvesicles shed by oligodendroglioma cells and rheumatoid synovial fibroblasts contain aggrecanase activity

2012

Membrane microvesicle shedding is an active process and occurs in viable cells with no signs of apoptosis or necrosis. We report here that microvesicles shed by oligodendroglioma cells contain an ‘aggrecanase’ activity, cleaving aggrecan at sites previously identified as targets for adamalysin metalloproteinases with disintegrin and thrombospondin domains (ADAMTSs). Degradation was inhibited by EDTA, the metalloproteinase inhibitor GM6001 and by tissue inhibitor of metalloproteinases (TIMP)-3, but not by TIMP-1 or TIMP-2. This inhibitor profile indicates that the shed microvesicles contain aggrecanolytic ADAMTS(s) or related TIMP-3-sensitive metalloproteinase(s). The oligodendroglioma cells…

LA FERRURE PÉRIPLANTAIRE, HISTOIRE D'UNE POLÉMIQUE

2014

Pierre Charlier, veterinarian of a transport company of Paris, presented 1765 a revolutionary method of far-riery. His horse shoe was made of an iron hook inlaid into the edge of the wall that limited the wear of the hoof while the sole and frog came into contact with the ground and limited slips. This patented device called into question the principles of the French method of farriery, threatened Parisian workshops owned by veterinarians in sight und thus unleashed a controversy of a rare violence that flourished the following year.
