Cover crop differentially affects arthropods, but not diseases, occurring on grape leaves in vineyards

2017

Background and Aims Cover crop has become a common management practice in viticulture. It improves the structure and protects the soil, enhances natural enemy populations and also reduces the vigour of the vine. Here, we investigated the effect of cover crop in vineyards on grapevine diseases and arthropods present on leaves. Methods and Results We measured the presence of the pathogens Plasmopara viticola, Uncinula necator and Guignardia bidwellii and monitored six common beneficial/pest arthropods: Panonychus ulmi, Orthotydeus lambi, Typhlodromus pyri, Scaphoideus titanus and Phalangium opilio in vineyards with cover crop or bare soil in 2014 and 2015. The density of the two pests P. ulmi…

Multilocus sequence typing confirms the close genetic inter-relatedness between three distinct flavescence doree phytoplasma strain clusters and grou…

ABSTRACT Vineyards of southern France and northern Italy are affected by the flavescence dorée (FD) phytoplasma, a quarantine pathogen transmitted by the leafhopper of Nearctic origin Scaphoideus titanus . To better trace propagation of FD strains and identify possible passage between the vineyard and wild plant compartments, molecular typing of phytoplasma strains was applied. The sequences of the two genetic loci map and uvrB - degV , along with the sequence of the secY gene, were determined among a collection of FD and FD-related phytoplasmas infecting grapevine, alder, elm, blackberry, and Spanish broom in Europe. Sequence comparisons and phylogenetic analyses consistently indicated the…

The Advantages of Type III Scaphoid Nonunion Advanced Collapse (SNAC) Treatment With Partial Carpal Arthrodesis in the Dominant Hand: Results of 5-ye…

2018

Introduction The SNAC wrist (Scaphoid nonunion advanced collapse) is one of the complications following scaphoid fractures treated conservatively and one of the causes of wrist arthritis that the hand surgeon has to face most frequently. In these cases surgical management is usually warranted. Materials and methods In the set time frame of 6 years we treated 15 SNAC wrist cases. On average patients underwent surgery five years after the trauma. All patients were treated via dorsal incision with partial carpal arthrodesis and total scaphoidectomy, associated with denervation of the posterior interosseous nerves. A plaster cast was applied to all patients for 3 weeks postoperatively. In the p…

Purpose The use of new headless compression screws (HCSs) for scaphoid fixation is growing, but the nonunion rate has remained constant. The aim of this study was to compare the stability of fixation resulting from four modern HCSs using a simulated fracture model to determine the optimal screw design(s). Methods We tested 40 fresh-frozen cadaver scaphoids treated with the Acumed Acutrak 2 mini (AA), the KLS Martin HBS2 midi (MH), the Stryker TwinFix (ST) and the Synthes HCS 3.0 with a long thread (SH). The bones with simulated fractures and implanted screws were loaded uniaxially into flexion for 2000 cycles with a constant bending moment of 800 Nmm. The angulation of the fracture fragment…

Étienne Destot (1864–1918) : l’anatomie radiographique

2014

Destot was born in Dijon, France, in 1864. He began his education in Burgundy, then he started his preclinical curriculum in Lyon, France, from 1884. He had to leave Lyon, and spent some times in Algeria to treat a tuberculosis. He came back in Lyon as a resident in 1886. Destot worked as an assistant in the laboratory of anatomy of Leo Testut in 1880. His thesis, in 1892, analyzed mortality in the departments of surgery of the Lyon hospitals. The polemical results he presented compromised his surgical career. He went on as prosector by Leo Testut, and then became electrician-physician in 1895 (electrotherapy and galvanotherapy). Etienne Destot of Lyon, France, developed in 1895 the first r…

Complicanze delle fatture dello scafoide carpale

2016

Le fratture dello scafoide carpale sono relativamente rare e avvengono soprattutto nei giovani in seguito a traumi ad alta energia. Per via della sua particolare conformazione anatomica e per la sua vascolarizzazione, è importante un’attenta valutazione del tipo di frattura per individuare il più corret- to approccio terapeutico, al ne di prevenire le non rare complicanze quali: ritardo di consolidazione, viziosa consolidazione e pseudoartrosi. Diverse sono le classi cazioni delle fratture e delle pseudoartrosi proposte da vari autori, le quali convergono sull’importanza della valutazione della stabilità dei frammenti. Le fratture di scafoide stabili bene ciano in genere di un trattamento i…
