Effect of low-dose methyl prednisolone on serum cytokine levels following extracorporeal circulation
Authors:
Publisher and Date:(Arnold Hodder Headline Plc., 1999)The systemic inflammatory response to cardiopulmonary bypass (CPB) is associated with increased production of cytokines. This systemic inflammatory response characterized by the activation of interleukin-6 (IL-6) and interleukin-8 (IL-8) during and after CPB is well documented. A prospective randomized double-blind study was performed so as to understand the effects of low-dose methyl prednisolone sodium succinate (MPSS) on the circulating levels of serum cytokines and clinical outcome.

Association of lipoprotein(a) concentration and apo(a) isoform size with restenosis after percutaneous transluminal coronary angioplasty
Authors:
Publisher and Date:(Springer Verlag, 2000)Lp(a) is a unique class of lipoprotein particles that exhibits a considerable size heterogeneity resulting from the size polymorphism of apo(a) its unique protein component. An elevated level of Lp(a) in plasma has been proposed to be a risk factor for premature development of coronary artery disease. To evaluate the relationship between Lp(a) concentration and apo(a) isoform size with restenosis after percutaneous transluminal coronary angioplasty Lp(a) levels and apo(a) phenotypes were determined ...

A synthesis tool for the multiplierless realization of FIR-based multirate DSP systems
Authors:
Publisher and Date:(IEEE, 2000)In this study a synthesis tool using a novel multirate folding technique which handles each FIR filter in a multirate DSP system as a single node is developed. A new architecture is presented for the multiplierless realization of a fold of multirate FIR filters. This synthesizer fully exploits the redundancies (i.e. `idle' and `missing' cycles) and common terms in multirate systems without sacrificing from overall system quality to produce multiplierless multirate systems. It also enables the usage ...

Off-pump coronary artery bypass grafting with use of the octopus 2 stabilization system
Authors:
Publisher and Date:(2000)Background: The treatment of coronary artery disease has evolved rapidly over the last two decades. The gold standard of surgical revascularization, the on-pump coronary artery bypass graft, has been challenged by the development of percutaneous transluminal coronary angioplasty. Our experience with the alternative of the off-pump ("beating heart") coronary artery bypass (OPCAB) technique during a period of 18 months suggests that OPCAB avoids the complications of cardiopulmonary bypass and offers ...

Primary epiploic appendagitis CT manifestations
Authors:
Publisher and Date:(Elsevier Science Inc, 2000)Inflammation of an epiploic appendage is considered to be a rare cause of acute abdomen. Recently it has been reported that typical computed tomography (CT) findings of primary epiploic appendagitis (PEA) provide a definitive diagnosis in most of the cases. However since these papers are only few they are easily overlooked by the practicing radiologists. Our purpose is to add four new cases to the existing literature and to perform a review of the literature. (C) 2001 Elsevier Science Inc. All ...

New modification in otoplasty: Anterior approach
Authors:
Publisher and Date:(Lippincott Williams & Wilkins, 2001)After harvesting the conchal cartilage in a large series of secondary rhinoplasties using the anterior approach there was a marked improvement in the shape of the auricle with unnoticeable scarring hidden under the convolution of the antihelix. In this series of 250 cases there were no hypertrophic scars or keloid formations. Based on these favorable results a new modification of otoplasty was developed using only the anterior approach. Between 1992 and 2000 108 otoplasties were performed on 55 ...

Reconstruction of the superior labial sulcus in secondary bilateral cleft lip deformities: An inverted U-shaped flap
Authors:
Publisher and Date:(Lippincott Williams & Wilkins, 2001)A shallow buccal sulcus deformity following bilateral cleft lip repair is not rare. A variety of techniques are described for the secondary reconstruction of a deficient sulcus. Most of these are associated with a variable amount of contraction with subsequent obliteration of the sulcus. In this article an inverted U-shaped flap is described for the secondary reconstruction of the deficient sublabial sulcus. In these patients mobility of the upper lip was severely restricted so orthodontic treatment ...

Removal of UroLume endoprosthesis using holmium : YAG laser
Authors:
Publisher and Date:(Mary Ann Liebert Inc Publ, 2001)A potential complication of UroLume endoprosthesis is migration which may necessitate removal of the stent. Stent removal may be associated with complications such as urethral injury bleeding and external sphincter trauma. We report a patient in whom a holmium:yttrium-aluminium-garnet (Ho:YAG) laser was used to cut the UroLume endoprosthesis into fragments which led to easy and uneventful stent removal.

Fault-tolerant training of neural networks in the presence of MOS transistor mismatches
Authors:
Publisher and Date:(IEEE-INST Electrical Electronics Engineers Inc, 2001)Analog techniques are desirable for hardware implementation of neural networks due to their numerous advantages such as small size low power and high speed. However these advantages are often offset by the difficulty in the training of analog neural network circuitry. In particular training of the circuitry by software based on hardware models is impaired by statistical variations in the integrated circuit production process resulting in performance degradation. In this paper a new paradigm of ...
