The design of lter banks for source coding purposes classically relies on the perfect reconstruction (PR) property. However, several recent studies have shown that taking the quantization noise into account in the design could yield noticeable reduction of the mean square reconstruction error. The purpose of this study is to show that perceptual improvement can also be obtained in the particula...

As exigências por maior competitividade e eliminação dos desperdí­cios tem motivado as organizações a implantarem Produção Enxuta (PE). Entretanto, esta tendência é muito mais notória na maioria das grandes empresas do que nas Micro Pequenas Empresas (MPE). É ante lacuna este artigo como objetivo propor um conjunto de diretrizes para implantação da (PE) (MPE) segmento indústria confecções local...

Malignant pleural effusion (MPE) is a common, debilitating complication of several types of advanced malignancy, which may significantly reduce the quality of life of patients. There are several options to treat MPE, including thoracentesis, placement of a long-term indwelling pleural catheter and chemical pleurodesis. The best treatment is still debated, but talc remains the agent of choice to...

BACKGROUND The role of tumour markers such as carbohydrate antigen (CA) 125, CA 15-3, CA 19-9 and CYFRA 21-1 (a fragment of cytokeratin 19) in differentiating malignant pleural effusions (MPE) from benign effusions is not yet clear. METHODS After a systematic review of English language studies, sensitivity, specificity and other measures of accuracy of pleural concentrations of CA 125, CA 15-...

MM with bortezomib, a proteasome inhibitor known for its remarkable efficacy in treating extramedullary MM. Although the pathogenesis of MPE is unknown, it is theorized that it may be a direct extension of thoracic myelomatous involvement. A review of 57 cases [9] demonstrated that half of the patients with MPE had concomitant thoracic skeletal, lung parenchymal, or chest wall plasmacytomas, wh...

Background: Lamotrigine (LTG) is commonly used for treatment of epilepsy and bipolar disorder. It is one of the common cause of cutaneous adverse drug reactions (CADR). Clinical symptoms of LTG-induced CADR range from maculopapular exanthema (MPE) to severe cutaneous adverse reactions (SCAR). This study aimed to determine the association of the LTG-induced CADR with human leukocyte antigen (HLA...

Drug allergic reactions presenting as maculo-papular exanthema (MPE) are mediated by drug-specific T cells. In this study, the frequency of circulating specific T cells was analyzed by interferon-gamma (IFN-gamma) enzyme-linked immunospot assay in 22 patients with an allergic MPE to amoxicillin (amox). Amox-specific circulating T cells were detected in 20/22 patients with frequencies ranging fr...

To discuss the differences in protein expression among tuberculosis pleural effusion (TBPE), malignant pleural effusion (MPE) and transudative pleural effusion (TSPE). We recruited 50 patients with pleural effusion, including 20 TBPEs, 17 MPEs and 13 TSPEs. Using the two-dimensional electrophoresis (2-DE) and matrix-assisted laser desorption ionization-time of flight-mass spectrometry (MALDI-TO...

In this paper, a reversible data hiding scheme based on modification of prediction errors (MPE) is proposed. For the existing histogram-shifting based reversible data hiding techniques, though the distortion caused by embedding is low, the embedding capacity is limited by the frequency of the most frequent pixel. To remedy this problem, the proposed method modifies the histogram of prediction e...

BACKGROUND Conventional biomarkers cannot always establish the cause of pleural effusions; thus, alternative tests permitting rapid and accurate diagnosis are required. The primary aim of this study is to assess the ability of pentraxin-3 (PTX3) in order to diagnose the cause of pleural effusion and compare its efficacy to that of other previously identified biomarkers. METHODS We studied 118...
