Cation vacancy diffusion on the NiO(001) surface by molecular dynamics simulations
(1999)We present results concerning the cation vacancy diffusion mechanisms occurring on the NiO(001) surface along with their corresponding migration energies. Using a rigid ion potential and molecular dynamics simulations we ... -
Causal ordering of physical self-concept and exercise behavior: Reciprocal effects model and the influence of physical education teachers
(2006)Does prior physical self-concept influence subsequent exercise behavior? On the basis of a large sample of physical education classes (2,786 students, 200 classes, 67 teachers) collected early (Time 1) and late (Time 2) ... -
Causal relationships of sport and exercise involvement with goal orientations, perceived competence and intrinsic motivation in physical education: A longitudinal study
(2006)Little information exists about the causal relationships of sport and exercise participation with goal orientations, perceived athletic competence and intrinsic motivation in physical education. A longitudinal study was ... -
Causes and Risk Factors of Cerebral Ischemic Events in Patients with Atrial Fibrillation Treated with Non-Vitamin K Antagonist Oral Anticoagulants for Stroke Prevention: The RENo Study
(2019)Background and Purpose-Despite treatment with oral anticoagulants, patients with nonvalvular atrial fibrillation (AF) may experience ischemic cerebrovascular events. The aims of this case-control study in patients with AF ... -
Causes of blindness and vision impairment in 2020 and trends over 30 years, and prevalence of avoidable blindness in relation to VISION 2020: The Right to Sight: An analysis for the Global Burden of Disease Study
(2021)Background: Many causes of vision impairment can be prevented or treated. With an ageing global population, the demands for eye health services are increasing. We estimated the prevalence and relative contribution of ... -
CB1R-dependent activation of Fyn tyrosine kinase and protein kinase C Delta, PKCδ, in lipid rafts
(2008)Cannabinoid 1 receptors (CB1Rs) are heptahelical transmembrane receptors which may exert their effects through the activation of the extracellular signal-regulated kinases (ERKs). We have previously shown that stably ... -
Ccn2 aggravates the immediate oxidative stress–dna damage response following renal ischemia–reperfusion injury
(2021)AKI, due to the fact of altered oxygen supply after kidney transplantation, is characterized by renal ischemia–reperfusion injury (IRI). Recent data suggest that AKI to CKD progression may be driven by cellular senescence ... -
CD10 Is Inversely Associated with Nuclear Factor-Kappa B and Predicts Biochemical Recurrence after Radical Prostatectomy
(2012)Introduction: The cell surface endopeptidase CD10 (neutral endopeptidase) and nuclear factor-kappa B (NF-kappa B) have been independently associated with prostate cancer (PC) progression. We investigated the correlations ... -
CD33 rs3865444 as a risk factor for Parkinson's disease
(2021)Background: Alzheimer's (AD) and Parkinson's diseases (PD) share a few elements of their clinical, pathological and genetic backgrounds. The CD33 rs3865444 has emerged as a strong genetic locus associated with AD through ... -
CD8+ PD-1+ T-cells and PD-L1+ circulating tumor cells in chemotherapy-naïve non-small cell lung cancer: towards their clinical relevance?
(2019)Background: Since tumor cells may escape from immune surveillance through the programmed cell death 1 (PD-1)/programmed death ligand (PD-L)1 axis, this study was designed in order to evaluate whether there is a correlation ... -
CD8+T lymphocytes in bronchoalveolar lavage in idiopathic pulmonary fibrosis
(2007)Background. Recently it was shown that in Idiopathic Pulmonary Fibrosis (IPF) tissue infiltrating CD8+ T lymphocytes (TLs) are associated with breathlessness and physiological indices of disease severity, as well as that ... -
CD8+T-cell auto-reactivity is dependent on the expression of the immunoproteasome subunit LMP7 in exposed to lipopolysaccharide antigen presenting cells and epithelial target cells
(2013)Proteasome generates peptides for presentation to CD8+ T-cells by antigen presenting cells (APCs) and peripheral cells. Inflammation alters proteasome to immunoproteasome, producing a different pool of peptides. The effect ... -
CD90/Thy-1, a cancer-associated cell surface signaling molecule
(2019)CD90 is a membrane GPI-anchored protein with one Ig V-type superfamily domain that was initially described in mouse T cells. Besides the specific expression pattern and functions of CD90 that were described in normal tissues ... -
CDK-inhibitor olomoucine inhibits cell death after exposure of cell lines to cytosine-arabinoside
(1999)Signal transduction for apoptosis or programmed cell death, after DNA damage in mammalian cells, is believed to involve activation of cyclin-dependent kinases (CDKs), especially CDK-1 (cdc2) and CDK-2. We used CDK-inhibitor ...
