Mitochondria play a pivotal role in apoptosis in multicellular organisms by releasing apoptogenic factors such as cytochrome c that activate the caspases effector pathway, and apoptosis-inducing factor (AIF) that is involved in a caspase-independent cell death pathway. Here we report that cell death in the single-celled organism Dictyostelium discoideum(More)
The centrality dependence of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at sqrt[s_{NN}]=2.76  TeV is presented. The charged-particle density normalized per participating nucleon pair increases by about a factor of 2 from peripheral (70%-80%) to central (0%-5%) collisions. The centrality dependence is found to be similar to(More)
OBJECTIVES The roots of the obesity epidemic need to be traced back as early in life as possible in order to develop effective means for preventing obesity and its health consequences in the future. The aim of this paper is to examine a broad range of factors that may simultaneously contribute to childhood overweight in a population-based cohort of children(More)
Intellectual disability (ID) is frequent in the general population, with 1 in 50 individuals directly affected worldwide. The multiple etiologies include X-linked ID (XLID). Among syndromic XLID, few syndromes present severe ID associated with postnatal microcephaly and midline stereotypic hand movements. We report on three male patients with ID, midline(More)
We previously described the generation of a set of mutations into a cDNA of poliovirus type 1 in the myristoylation signal of the capsid polypeptide VP4 (D. Marc, G. Drugeon, A.-L. Haenni, M. Girard, and S. van der Werf, EMBO J. 8:2661, 1989). Genomic transcripts synthesized in vitro from the mutated cDNAs were found to be noninfectious upon transfection of(More)
The first measurement of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at a center-of-mass energy per nucleon pair √ S NN = 2.76 TeV is presented. For an event sample corresponding to the most central 5% of the hadronic cross section, the pseudorapidity density of primary charged particles at midrapidity is 1584 ± 4(stat) ±(More)
OBJECTIVE To examine the relationship between consumption of sugar-sweetened beverages (eg, nondiet carbonated drinks and fruit drinks) and the prevalence of overweight among preschool-aged children living in Canada. DESIGN Data come from the Longitudinal Study of Child Development in Québec (1998-2002). SUBJECTS/SETTING A representative sample(More)
We recently compared the efficiency of six picornaviral internal ribosome entry segments (IRESes) and the hepatitis C virus (HCV) IRES for their ability to drive internal initiation of translationin vitro. Here we present the results of a similar comparison performed in six different cultured cell lines infected with a recombinant vaccinia virus expressing(More)
Relatively little is known about the human genetics of susceptibility to common diseases caused by bacterial pathogens. Tuberculosis, caused by Mycobacterium tuberculosis, is a major cause of morbidity and mortality worldwide. So far, genetic studies of tuberculosis susceptibility have largely been focused on adult patients despite the fact that(More)
On the basis of primary sequence comparisons and secondary structure predictions, picornavirus internal ribosome entry segments (IRESes) have been divided into three groups (entero- and rhinoviruses; cardio- and and aphthoviruses; and hepatitis A virus). Here, we describe a detailed comparison of the ability of IRESes from each group to direct internal(More)
