Small Ruminant Lentiviruses (SRLV) are widespread in Canadian sheep and goats and represent an important health issue in these animals. There is however no data about the genetic diversity of Caprine Arthritis Encephalitis Virus (CAEV) or Maedi Visna Virus (MVV) in this country. We performed a molecular and phylogenetic analysis of sheep and goat(More)
Development of antral follicles beyond 3 to 4 mm in cattle appears as a wave pattern that occurs two to three times during the estrous cycle. Each wave presents a cyclic recruitment of multiple follicles at the 3- to 4-mm stage, followed by the selection of a single follicle that becomes the dominant follicle (DF). The molecular determinants involved in the(More)
Prediction of coronary events remains elusive. Carotid atherosclerosis may be a surrogate for coronary risk, as carotid and coronary diseases occur simultaneously - albeit at times with a weak association - depending on clinical presentation. We investigated carotid and coronary atherosclerosis in men with new-onset unstable coronary artery disease (CAD)(More)
PURPOSE Despite the key role played by lifestyle habits in the epidemic of type 2 diabetes (T2D), nutritional quality and physical activity are not systematically considered in clinical practice. The project was conducted to verify whether assessing/targeting lifestyle habits could reduce hemoglobin A1c (HbA1c) levels of employees. METHODS The(More)
Although cardiovascular disease (CVD) and diabetes mellitus are largely lifestyle driven, lifestyle metrics are not used in clinical practice. This study examined the relevance of using a simple lifestyle risk score designed for primary care medicine by testing its ability to predict biological CVD risk factors in a cohort of 3,712 individuals involved in a(More)
Here we describe the establishment of size-selected cDNA libraries for the cloning of full-length cDNAs that were initially identified by suppression subtractive hybridization (SSH) technology as being differentially expressed. First, the SSH-cDNA fragments were used as 32P-probes to verify their level and differential pattern of expression by virtual(More)
BACKGROUND Patients with coronary artery disease (CAD) are characterized by an impaired cardiometabolic risk profile including high levels of atherogenic apolipoprotein (apo) B-containing lipoprotein levels. Genetic studies have highlighted a critical role for proprotein convertase subtilisin/kexin type 9 (PCSK9) in lipoprotein metabolism and CAD risk. (More)
Presensitization to HLA antigens limits the success of organ transplantation. The achievement of donor-specific tolerance via mixed chimerism could improve outcomes of transplantation in presensitized patients. In presensitized B-cell-deficient μMT B6 mice, we developed nonmyeloablative bone marrow transplantation (BMT) regimens that successfully tolerized(More)
PURPOSE The prevalence of numerous chronic metabolic diseases is increasing worldwide with considerable personal and societal consequences. The aim of our study was to test the hypothesis that assessment of waist circumference (WC) and of cardiorespiratory fitness (CRF) could be relevant clinical targets of a simple preventive approach designed to improve(More)
