The proliferating cell nuclear antigen (PCNA) sliding clamp lies at the heart of the accurate duplication of eukaryotic genomes. While the outer surface of the PCNA ring interacts with polymerases and other factors, the role of the inner wall facing the DNA is elusive. Recent evidence shows that conserved basic residues in the PCNA central channel create a specific surface that recognizes the DNA backbone and enables the clamp to slide by rotationally tracking the DNA helix. The sliding surface can be modulated (i) through lysine acetylation, which triggers PCNA degradation during nucleotide excision repair (NER) and stimulates repair by homologous recombination (HR) or (ii) through binding of the protein factor p15(PAF), which turns off DNA lesion bypass...

BACKGROUND: Atrial fibrillation (AF) is a type of cardiac arrhythmia which is commonly seen following lung resection. There is currently no algorithm which can predict which patients will develop postoperative AF (PAF). The present study aims to identify the risk factors for the development of PAF and high-risk patients with PAF along with multiple risk factors. MATERIALS AND METHODS: A total of 887 patients, who underwent lung resection due to primary lung malignancy at our clinic between January 2000 and December 2016, were retrospectively analysed...

Endothelial cells (EC) establish a physical barrier between the blood and surrounding tissue. Impairment of this barrier can occur during inflammation, ischemia or sepsis and cause severe organ dysfunction. Kindlin-2, primarily recognized as a focal adhesion protein in EC, was not anticipated to have a role in vascular barrier. We tested the role of Kindlin-2 in regulating vascular integrity using several different approaches to decrease Kindlin-2 levels in EC. Reduced levels of Kindlin-2 in Kindlin-2(+/-) mice, aortic endothelial cells (MAECs) from these(-) mice, and human umbilical ECs (HUVEC) treated with Kindlin-2 siRNA showed enhanced basal and Platelet Activating Factor (PAF) or lipopolysaccharide-stimulated vascular leakage compared to wild-type (WT) counterparts...

Human mast cells (MCs) and eosinophils were first described and named by Paul Ehrlich. These cells have distinct myeloid progenitors and differ morphologically, ultrastructurally, immunologically, biochemically, and pharmacologically. However, MCs and eosinophils play a pivotal role in several allergic disorders. In addition, these cells are involved in autoimmune disorders, cardiovascular diseases, and cancer. MCs are distributed throughout all normal human tissues, whereas eosinophils are present only in gastrointestinal tract, secondary lymphoid tissues, and adipose tissue, thymus, mammary gland, and uterus...

Formyl peptide receptor (FPR)-desensitized neutrophils display increased production/release of superoxide (O2(-)) when activated by platelet-activating factor (PAF), a priming of the response achieved through a unique receptor crosstalk mechanism. The aim of this study was to determine the effect of an inhibitor selective for small, heterotrimeric G proteins belonging to the Gαq subclass on that receptor crosstalk. We show that signals generated by FPRs and the PAF receptor (PAFR) induce activation of the neutrophil O2(-), producing NADPH-oxidase, and that response was sensitive to Gαq inhibition in cells activated by PAF, but no inhibition was obtained in cells activated by FPR agonists...

Neural oscillations, such as alpha (8-13 Hz), beta (13-30 Hz), and gamma (30-100 Hz), are widespread across cortical areas, and their possible functional roles include feature binding [1], neuronal communication [2, 3], and memory [1, 4]. The most prominent signal among these neural oscillations is the alpha oscillation. Although accumulating evidence suggests that alpha oscillations correlate with various aspects of visual processing [5-18], the number of studies proving their causal contribution in visual perception is limited [11, 16-18]...

In the present study, we investigated the course of atrophy in canine uterine tissue and the expression of estrogen receptors (ER) and progesterone receptors (PR) within 6 months after ovariectomy (OE). In nine primipar bitches of different breeds, bilateral OE and removal of one horn was performed. Six months after surgery, the remaining uterine tissue was removed. The tissue was examined for signs of inflammation and proliferation, and for expression of ER, PR and Ki67 by means of immunohistochemistry (IHC); furthermore transcription of vascular endothelial growth factor (VEGF), transforming growth factor-ß (TGF-ß), epithelial growth factor (EGF), platelet activating factor (PAF), tumor necrosis factor α (TNFα), and their specific receptors was determined by means of RT-qPCR...

OBJECTIVE: Non-valvular atrial fibrillation (NVAF) is frequently complicated by thromboembolism. Left atrial appendage (LAA) flow is a predictor of LAA thrombosis. LAA flow is measured by transesophageal echocardiography (TEE), which is a semi-invasive diagnostic tool. Recently, speckle-tracking methods have been adapted for the evaluation of local cardiac function. We hypothesised that if we could determine LAA wall motion utilising a speckle tracking technique, we could non-invasively analyse LAA flow...

The Woodcock-Johnson (fourth edition; WJ IV; Schrank, McGrew, & Mather, 2014a) was recently redeveloped and retains its linkage to Cattell-Horn-Carroll theory (CHC). Independent reviews (e.g., Canivez, 2017) and investigations (Dombrowski, McGill, & Canivez, 2017) of the structure of the WJ IV full test battery and WJ IV Cognitive have suggested the need for additional factor analytic exploration. Accordingly, the present study used principal axis factoring (PAF) followed by the Schmid and Leiman (SL; Schmid & Leiman, 1957) procedure with the 2 school-aged correlation matrices from the normative sample to determine the degree to which the WJ IV total battery structure could be replicated...

BACKGROUND: Development of atrial fibrillation after certain cardiac procedures is a common medical problem. The inflammatory process plays an important role in the pathogenesis of post-cardiac procedure atrial fibrillation (PCP-AF). Colchicine, a potent anti-inflammatory agent, has been used in several studies to reduce the risk of PCP-AF. This meta-analysis of randomized controlled trials (RCTs) was conducted to assess the efficacy of colchicine in prevention of PC-PAF. METHODS: We searched PubMed, EMBASE, Web of Science, Cochrane Library database and Google Scholar for RCTs, using terms "Atrial fibrillation, atrial, or fibrillation and colchicine"...

BACKGROUND: The extended illness-death model is a useful tool to study the risks and consequences of hospital-acquired infections (HAIs). The statistical quantities of interest are the transition-specific hazard rates and the transition probabilities as well as attributable mortality (AM) and the population-attributable fraction (PAF). In the most general case calculation of these expressions is mathematically complex. METHODS: When assuming time-constant hazards calculation of the quantities of interest is facilitated...

Polymorphonuclear granulocytes (PMN) are activated in inflammatory reactions. Intestinal epithelial cells are relevant for maintaining the intestinal barrier. We examined interactions of PMN and intestinal epithelial cell-like CaCo-2 cells to elucidate their regulation of inflammatory signalling and the impact of cyclooxygenase (COX), nitric oxide (NO) and platelet-activating factor (PAF). Human PMN and CaCo-2 cells, separately and in co-incubation, were stimulated with the calcium ionophore A23187 or with N-Formyl-methionyl-leucyl-phenylalanin (fMLP) that activates PMN only...

BACKGROUND: Detection of paroxysmal atrial fibrillation (PAF) in cryptogenic stroke is critical to selecting an antithrombotic therapy for preventing recurrent stroke. However, the predictor of PAF in patients with acute ischemic stroke is not well elucidated. P-wave terminal force in lead V1 (PTFV1) is a standard electrocardiogram marker of left atrial abnormality. In this study, we aimed to investigate the utility of PTFV1 for the prediction of PAF in patients with acute ischemic stroke...

INTRODUCTION: Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice and a major cause of morbidity, due to the associated risk of stroke. However, since it is often paroxysmal, it is commonly underdiagnosed and undertreated. OBJECTIVES: The primary objective of this prospective study was to determine the prevalence of paroxysmal atrial fibrillation (PAF) in patients aged 40 and above in a population who underwent continuous 24-hour electrocardiographic monitoring...
