Background: Leukoaraiosis (LA) or white matter thinning and rarefaction are common in stroke patients. This pilot double-center study was designed to evaluate LA risk factors in stroke patients. Methods: This cross sectional study was conducted on 100 consecutive stroke patients in Walter Mackenzie Hospital, Canada and 100 consecutive stroke patients in Valie-Asr Hospital, Iran in 2004. Diagnos...

INTRODUCTION Earlier reports of laparoscopic adrenalectomy (LA) for adrenal myelolipoma are limited. PRESENTATION OF CASE Between June 2000 and September 2012, we performed right adrenal resections using LA and open adrenalectomy (OA) in patients with myelolipoma (n = 3 and n = 3, respectively). Then, we evaluated patients' background characteristics and short- and long-term outcomes for both...

A complete, isostructural series of complexes with La-Lu (except Pm) with the ligand TREN-1,2-HOIQO has been synthesized and structurally characterized by means of single-crystal X-ray analysis. All complexes are 1D-polymeric species in the solid state, with the lanthanide being in an eight-coordinate, distorted trigonal-dodecahedral environment with a donor set of eight unique oxygen atoms. Th...

We study the decay of the energy for a degenerate network of strings[1], and obtain optimal decay rates when the lengths are all equal. We also define a classical space semi-discretization and compare the results with the exact method introduced in [3,4]. To cite this article: A. Name1, A. Name2, C. R. Acad. Sci. Paris, Ser. I 340 (2005). Résumé Taux de décroissance optimaux pour la stabilisati...

Leaf area (LA) is a valuable key for plant physiological studies, therefore accurate and simple models for LA determination are important for many experimental comparisons. A greenhouse experiment was conducted from October 2009 to February 2010 in two basil cultivars (Purple Ruffles and Genovese) to estimate LA, leaf dry weight (DW), leaf fresh weight (DW) and leaf dimensions (width-W and leng...

Objective: Duplex ultrasonography is a non-invasive, non-expensive screening test for carotid disease. Intima media thickness (IMT) is appropriate for atherosclerosis process diagnosis. Leukoaraisis (LA) increase the risk of cerebrovascular accident (CVA). LA patients need preventive medication for CVA. IMT is a non-invasive diagnostic and prognostic test in LA. The aim of this study was evalua...

jean-jacques rousseau, écrivain illustre et philosophe révolutionnaire de l’âge des lumières, a recouru pendant les dernières années de sa vie à l’écriture des ouvrages autobiographiques. il y refléta le véritable portrait de soi-même grâce à une mémoire encombrée de souvenirs tumultueux. son œuvre autobiographique qui comprend les confessions, les dialogues et les rêveries du promeneur solitai...

BACKGROUND Left atrial three-dimensional shape and contraction patterns are not well described. We quantified the LA using three-dimensional cardiac MRI (CMR) in a group of normal subjects. METHODS Three-dimensional vectors were used to quantitate atrial shape and contraction using a geometric model as a three-dimensional prolate ellipsoid. Atrial area and length at end-systole and end-diasto...

Introduction: The role of ovarian hormones and nitric oxide (NO) on oxidative damage in brain tissues as well as learning and memory has been widely investigated.The present study was carried out to evaluate the effect of the precursor of NO, L-Arginine on learning and brain damage due to oxidative stress in ovariectomized (OVX) rats.Methods: Thirty -two rats were divided into four groups: 1) S...

A linear arrangement (LA) is an assignment of distinct integers to the vertices of a graph. The cost of an LA is the sum of lengths of the edges of the graph, where the length of an edge is defined as the absolute value of the difference of the integers assigned to its ends. For many application one hopes to find an LA with small cost. However, it is a classical NP-complete problem to decide wh...
