Comparison between the inputs of photoreceptors with different spectral sensitivities is required for color vision. In Drosophila, this is achieved in each ommatidium by the inner photoreceptors R7 and R8. Two classes of ommatidia are distributed stochastically in the retina: 30% contain UV-Rh3 in R7 and blue-Rh5 in R8, while the remaining 70% contain(More)
INTRODUCTION Accurate implantation of the prosthesis components is a prognostic factor for long-term total knee arthroplasty survival as it reduces wear and loosening failure. Computer-assisted navigation systems have proved to produce accurate bone cuts orthogonal to the mechanical axis. Proper rotational alignment of the femoral component is one of the(More)
INTRODUCTION The importance of a dysplastic trochlea as a component of patellar instability has long been recognized. An original trochleoplasty technique consisting in retro-trochlear recession wedge osteotomy was described by Goutallier et al. The aim is not to fashion a groove but to reduce the bump without modifying patellofemoral congruence. PATIENTS(More)
AIMS Congestive heart failure (CHF) is associated with severe structural changes of atria, contributing to impaired atrial function and the risk of arrhythmia. This study investigated the effects of CHF treatments on atrial remodelling. METHODS AND RESULTS Three months after myocardial infarction (MI), rats were treated for 1 month with spironolactone,(More)
The Drosophila ommatidia contain two classes of photoreceptor cells (PR's), the outer and the inner PR's. We performed an enhancer trap screen in order to target genes specifically expressed in PR's. Using the UAS/GAL4 method with enhanced green fluorescent protein (eGFP) as a vital marker, we screened 180000 flies. Out of 2730 lines exhibiting new eGFP(More)
BACKGROUND Studies evaluating healing of repaired meniscus are rare and primarily retrospective. The aim of this study was to assess whether there were different healing rates for arthroscopic meniscal repair with respect to the different zones of the meniscus. PURPOSE This study was conducted to assess outcomes and to document anatomic characteristics of(More)
INTRODUCTION Various surgical techniques have been described to set the rotational alignment of the tibial baseplate during total knee arthroplasty. The self-positioning method ("self-adjustment") aligns the tibial implant according to the rotational alignment of the femoral component which is used as a reference after performing repeated knee(More)
PURPOSE Symptomatic horizontal meniscal tears in young patients are a singular entity. The extent of the lesion is often large, without any injury to the knee. The meniscal tissue might be degenerative. However, a complete resection of the lesion would result in a subtotal meniscectomy. The purpose of this study was to consider the use of a meniscal repair(More)
INTRODUCTION Discoid medial meniscus is a rare abnormality, with incidence estimated at 0.12%. The present study describes this congenital abnormality anatomically and reports clinical results in four symptomatic cases managed by surgery. MATERIALS AND METHOD A retrospective study included three patients (2 female, 1 male), one of whom had bilateral(More)
Rupture of the Achilles tendon is a considerable cause of morbidity with reduced function following injury. Recent studies have shown little difference in outcome between the techniques of open and non-operative treatment using an early active rehabilitation programme. Meta-analyses have shown that non-operative management has increased risk of re-rupture(More)
