Impaired serum cholesterol efflux capacity in rheumatoid arthritis and systemic lupus erythematosus.
OBJECTIVES The marked cardiovascular risk in autoimmune diseases is only partly explained. The capacity of high-density lipoproteins (HDL) to promote cell cholesterol efflux is a property with a well-known anti-atherogenic significance, but is also involved in functional modulation of endothelial and immune cells. The aim of this work was to evaluate HDL functionality with respect to cell chole...
German and French abstracts see p. 49 & 50 Background: Whose interests should a hospital clinical ethics committee (CEC) serve? This is a particularly important question in conflicts regarding life and death decisions. This question has been raised in Norway by clinicians, politicians and lay people. Method: A retrospective evaluation of six high conflict cases discussed in CECs, all dealing wi...
Decades of epidemiologic studies have firmly established the inverse relationship between HDL-cholesterol (HDL-C) levels and cardiovascular events.1 However, the resulting hypothesis that raising HDL-C levels should reduce cardiovascular disease (CVD)has been called into questionby the failure of recent trials designed to decrease CVD events, despite raising HDL-C levels with cholesteryl ester ...
In this study, an open-tubular capillary electrochromatography (OT-CEC) column with a monolithic layer of molecularly imprinted polymer (MIP) based on methacrylic acid, ethylene glycol dimethacrylate, and 4-styrenesulfonic acid was utilized for the simultaneous separation and characterization of phospholipid (PL) molecular structures by interfacing with electrospray ionization-tandem mass spect...
Video streaming over vehicular networks is an attractive feature to many applications, such as emergency video transmission and inter-vehicle video transmission. Vehicles accessing road-side units have a few seconds to download information and experience a high packet loss rate. Hence, this paper proposes Cooperative Error Control (CEC) mechanism combining Cognitive Technology (CT) for video st...
از آنجایی که 4-متیل سیولتین خاصیت آنتی اکسیدانی دارد بنابراین بررسی اکسیداسیون این ترکیب می تواند حائز اهمیت باشد. در قسمت اول، بررسی رفتار و اکسایش الکتروشیمیایی 4-متیل سیولتین به تنهایی و در حضور کلروبنزن سولفینیک به عنوان نوکلئوفیل در آب و استونیتریل (1 به 1 v/v) با استفاده از ولتامتری چرخه ای و کولومتری در پتانسیل کنترل شده مورد مطالعه قرار گرفته است. نتایج نشان می دهد که این ترکیب بعد از ا...
سابقه و هدف: کمیسیون جامعه اروپایی (the commission of european communities-cec) راهنمایی را تدوین کرده است که در آن برای بسیاری از آزمون های رادیوگرافی رایج، بهترین شرایط کارتعیین گردیده که با ملاحظه منفعت بیمار با پیروی از آن هردو مولفه کیفیت تصاویر رادیوگرافی و کاهش میزان دز به بیمار تضمین می گردد. عدم انطباق مراکز رادیولوژی با راهنماهای استاندارد نه تنها منجر به کاهش کیفیت تصاویر رادیوگرافی ...
PURPOSE The randomized HD2000 trial compared six cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine), four escalated plus two standard cycles of BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone), and six cycles of COPP-EBV-CAD (cyclophosphamide, lomustine, vindesine, melphalan, prednisone, epidoxorubicin, vincristine, proc...
BACKGROUND Circulating endothelial cells (CECs) are widely reported as a promising biomarker of endothelial damage/dysfunction in coronary artery disease (CAD). The two popular methods of CEC quantification include the use of immunomagnetic beads separation (IB) and flow cytometry analysis (FC); however, they suffer from two main shortcomings that affect their diagnostic and prognostic response...
JUSTIFICATIVA E OBJETIVOS: As doenças congênitas do coração atingem 0,8% dos recém-nascidos (RN) vivos, sendo que muitos necessitam de correção cirúrgica ainda no período neonatal. A cirurgia cardíaca com circulação extracorpórea (CEC), nesta faixa etária, associa-se a maior incidência de complicações, devido à imaturidade funcional da criança, à falta de equipamentos de CEC que sejam totalment...
