The cohesin complex is crucial for chromosome segregation during mitosis and has recently also been implicated in transcriptional regulation and chromatin architecture. The NIPBL protein is required for the loading of cohesin onto chromatin, but how and where cohesin is loaded in vertebrate cells is unclear. Heterozygous mutations of NIPBL were found in 50% of the cases of Cornelia de Lange Syn...
BACKGROUND Self-injurious and aggressive behaviours are reported as components of some behavioural phenotypes but there are few studies comparing across syndrome groups. In this study we examined the prevalence of these behaviours and the associated person characteristics in seven genetic syndromes. METHODS Questionnaire data on self-injury and aggression, mood, hyperactivity, autism spectrum...
We consider an optimization problem on the maximal magnitude of angular acceleration output-links a commercially available center-driven linkage system (CDLS) for vehicle wipers windshield. The purpose this is to improve steadiness without weakening its normal function. Thus considered under assumptions that frame fixed links unchanged and input-link rotates at same constant speed with length u...
Cornelia de Lange syndrome (typus degenerativus amstelodamensis, CdLS, Brachmann syndrome) is a complex, congenital, multi-gene anomaly characterized by mental retardation. Its features include growth inhibition, hirsutism, structural anomalies of the limbs and abnormal development of osseous structures of the face. Independent of the phenotype of the disease, 85% of patients are assumed to hav...
A theory of the origin of eukaryotic cells ("higher" cells which divide by classical mitosis) is presented. By hypothesis, three fundamental organelles: the mitochondria, the photosynthetic plastids and the (9+2) basal bodies of flagella were themselves once free-living (prokaryotic) cells. The evolution of photosynthesis under the anaerobic conditions of the early atmosphere to form anaerobic ...
Cornelia de Lange Syndrome (CdLS) is a multi-organ system birth defects disorder linked, in at least half of cases, to heterozygous mutations in the NIPBL gene. In animals and fungi, orthologs of NIPBL regulate cohesin, a complex of proteins that is essential for chromosome cohesion and is also implicated in DNA repair and transcriptional regulation. Mice heterozygous for a gene-trap mutation i...
Cornelia de Lange syndrome (CdLS) is a congenital developmental disorder characterized by craniofacial dysmorphia, growth retardation, limb malformations, and intellectual disability. Approximately 60% of patients with CdLS carry a recognizable pathological variant in the NIPBL gene, of which two isoforms, A and B, have been identified, and which only differ in the C-terminal segment. In this w...
BACKGROUND AND OBJECTIVES Factors that contribute to difficult laparoscopic cholecystectomy (LC) in acute cholecystitis (AC) that would affect the performance of early surgery remain unclear. The purpose of this study was to identify such risk factors. METHODS One hundred fifty-four patients who underwent LC for AC were retrospectively analyzed. The patients were categorized into early surger...
Cornelia de Lange syndrome (CdLS) is a congenital developmental disorder characterized by distinctive craniofacial features, growth retardation, cognitive impairment, limb defects, hirsutism, and multisystem involvement. Mutations in five genes encoding structural components (SMC1A, SMC3, RAD21) or functionally associated factors (NIPBL, HDAC8) of the cohesin complex have been found in patients...
