In this paper a new class of transforms named Predictionbased Lower triangular Transform (PLT) is introduced for signal compression. The PLT is a nonunitary transform that yields the same coding gain as the Kahunen-Loeve transform (KLT). Unlike KLT, the derivation of PLT does not involve any eigen problem. An M-dimensional PLT can be solved by Levinson-Durbin recursion formula in O ( M 2 ) . Mo...

BACKGROUND Blood transfusions are common during hematopoietic stem cell transplantation (HSCT) and may contribute to lung injury. STUDY DESIGN AND METHODS This study examined the associations between red blood cell (RBC) and platelet (PLT) transfusions and idiopathic pneumonia syndrome (IPS) among 914 individuals who underwent myeloablative allogeneic HSCT between 1997 and 2001. Patients rece...

Microparticles (MP) shed by platelets (PLT) during storage have procoagulant activities, but little is known about their properties to modify inflammation or immunity. In this study, we studied the capacity of MP present in PLT concentrates to alter the function of macrophages and dendritic cells (DC). The size of the purified MP was between 100 and 1000 nm, and they expressed phosphatidylserin...

Although angiogenesis is viewed as a fundamental component of inflammatory bowel disease (IBD) pathogenesis, we presently lack a thorough knowledge of the cell type(s) involved in its induction and maintenance in the inflamed intestinal mucosa. This study aimed to determine whether platelet (PLT) adhesion to inflamed intestinal endothelial cells of human origin may favour angiogenesis. Unstimul...

The aim of the present study was to investigate the prognostic value of different pretreatment platelet (PLT) counts on the treatment outcome in nasopharyngeal carcinoma (NPC) patients receiving concurrent chemoradiotherapy (CCRT) or radiotherapy (RT) alone. A total of 1,501 NPC patients, including 412 receiving CCRT and 1,089 receiving RT, were enrolled in the present study. The PLT count cut-...

BACKGROUND Protected learning time (PLT) has spread quickly to primary healthcare teams in Scotland. Previous research has shown that PLT is generally well received, but that different professional and occupational groups have differing perceptions and experiences of PLT. Community nurses have low rates of attendance at practice-based PLT in NHS Ayrshire and Arran. It is not known why. AIMS T...

The encounter between APC and T cells is crucial for initiating immune responses to infectious microorganisms. In the spleen, interaction between dendritic cells (DC) and T cells occurs in the periarteriolar lymphoid sheath (PALS) into which DC and T cells migrate from the marginal zone (MZ) along chemokine gradients. However, the importance of DC migration from the MZ into the PALS for immune ...

Transfused platelets (plts) are either pooled random-donor platelet (plt) concentrates or single-donor apheresis plts. When stored for 5 days, all of these products are equally efficacious. A 10,000/microL prophylactic plt transfusion trigger has been documented to be both hemostatically efficacious and cost effective in reducing plt transfusion requirements. The optimal plt dose/transfusion is...

OBJECTIVE To determine and optimize the sensitivity of the CellaVision DM96 automated image-analysis system in detecting platelet (PLT) clumps on blood smears and to assess the reliability of the traditional laboratory practice of examining only the feather edge of the smear for PLT clumps. METHODS We processed 102 blood smears that revealed PLT clumps on microscopic review, using the CellaVi...

AIM To rule out maternal and pregnancy factors that may contribute to platelet count (PLT) changes in the first trimester of gestation and examine if there is any association between its levels and adverse perinatal outcome. METHODS The study population included all patients from the first-trimester visit between 2013-2015 with pregnancy results. Linear multiple regression was constructed to ...
