For patients with Wolff-Parkinson-White (WPW) syndrome, several algorithms have been published for the prediction of the location of accessory pathways (APs) from the QRS morphology on the ECG. Hence, these algorithms may fail to identify the locations of midseptal or right APs (1, 2). APs may traverse the central fibrous trigone or involve the right atrial appendage; these may be mistaken as a...
Antiphospholipid antibody syndrome (APS) is usually a disease of young adults. In elderly stroke patients APS was not associated with progressive intracerebral stenosis in the past. Here, we report a 65-year-old patient who presented with recurrent ischemic strokes associated with progressive stenosis of the right middle cerebral artery. Antiphospholipid antibodies were detected and treatment w...
Polymeric alkylpyridinium salts (poly-APS) isolated from the marine sponge Reniera sarai act as antifouling and anticholinesterase agents. They also show moderate haemolytic and cytotoxic activities against different cell lines. The haemolytic activity of poly-APS is due to their detergent-like structure and behaviour in aqueous solutions. In this work, the lytic activity of poly-APS against fr...
Autoimmune polyglandular syndromes (APS) comprise a wide clinical spectrum of autoimmune disorders. APS is divided into Type I, Type II, Type I and Type IV depending upon the pattern of disease combination. Ghronic diarrhoea is one of the many manifestations of APS and many aetiological factors have been suggested for it. Apart from the established aetiological factors, intestinal lymphangiecta...
Water-soluble polymeric 3-alkylpyridinum salts (poly-APS), isolated from the marine sponge Reniera sarai, are natural products with promising biomedical applications. However, their ability to form non-specific cell membrane pores raises safety issues. Therefore, the aim of the present study was to investigate the direct toxic effects of poly-APS on the cardiovascular system. To study the impac...
Objectives. No data regarding phenotypic assets of circulating lymphocytes in antiphospholipid syndrome (APS) are reported in the literature. Role of anti-phospholipid antibodies (aPL) in recurrent spontaneous abortion (RSA) remains uncertain, while natural killer (NK)-cells are involved in RSA pathogenesis. In this study, patients affected with APS without RSA, APS with RSA and RSA without aPL...
BACKGROUND AND PURPOSE Antiphosphatidylserine antibodies (aPS) have been associated with the risk of ischemic stroke. However, it remains unclear whether aPS will influence clinical outcomes in patients with acute ischemic stroke. METHODS A total of 3013 patients with acute ischemic stroke recruited from 26 hospitals across China from August 2009 to May 2013 were included in the study The pri...
An aggregate signature is a single short string that convinces any verifier that, for all 1 ≤ i ≤ n, signer i signed message mi, where the n signers and n messages are distinct. The main motivation of aggregate signatures is compactness. In this paper, the concept of aggregate proxy signature (APS) is first proposed to compact the proxy signatures. Furthermore, a concrete APS scheme is construc...
Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by vascular thrombosis or pregnancy morbidity. Ocular involvement in APS includes a broad spectrum of manifestations involving anterior and posterior segment or the presence of neuroophthalmologic features. Nonarteritic anterior ischemic optic neuropathy (NAION) is a very rare finding, and in this report a case having NAION...
