Alzheimer's disease (AD) is an age-associated disease. Mutations in the amyloid precursor protein (APP) may be causative or protective of AD. The presence of two functionally redundant APP-like genes (APLP1/2) has made it difficult to unravel the biological function of APP during aging. The nematode Caenorhabditis elegans contains a single APP family member, apl-1. Here, we assessed the functio...

Myasthenia gravis is a T cell-dependent, antibody-mediated autoimmune disease. A dual altered peptide ligand (APL) that is composed of the tandemly arranged two single amino acid analogs of two myasthenogenic peptides, p195-212 and p259-271, was demonstrated to down-regulate in vitro and in vivo myasthenia gravis-associated autoreactive responses. The aims of this study were to demonstrate the ...

Acute promyelocytic leukemia (APL) represents a subtype of acute myeloid leukemia with characteristic morphologic, molecular, and immunophenotypic features. Previous immunophenotypic analyses have shown that leukemic cells in APL typically express the myeloid markers CD33 and CD13 but lack expression of the early hematopoietic progenitor cell antigens CD34 and HLA-DR. We analyzed selected immun...

The term "antiphospholipid syndrome" (APS) was coined in the early '80s to describe a unique form of acquired autoimmune thrombophilia, with clinical features of recurrent thrombosis and pregnancy morbidity, combined with the presence of antiphospholipid antibodies (aPL). aPL consist a heterogeneous group of autoantibodies, which recognize phospholipid-protein complexes or rather proteins with ...

The antiphospholipid syndrome (APS) is characterized by recurrent fetal loss, vascular thrombosis, and thrombocytopenia occurring in the presence of antiphospholipid (aPL) antibodies. The pathogenesis of fetal loss and tissue injury in APS is incompletely understood, but is thought to involve platelet and endothelial cell activation as well as procoagulant effects of aPL antibodies acting direc...

The persistent presence in plasma of medium to high levels of IgG and/or IgM class anticardiolipin antibodies (aCL) and/or the lupus anticoagulant (LAC) is associated with both “recurrent pregnancy loss” and venous and arterial thrombosis. This clinicoserological entity, first described in the early eighties in patients with systemic lupus erythematosus was termed the antiphospholipid syndrome ...

Since the 1980s it is known that an important thrombogenic mechanism is mediated by antiphospholipid antibodies (aPL). Aim of this review is to discuss how much aPL presence may worsen the thrombophilic state of neoplastic patients and how much cancer may worsen and extend the thrombophilic state of patients with Antiphospholipid Syndrome (APS). In the last years a higher prevalence of aPL was ...

BACKGROUND Drosophila olfactory aversive conditioning produces two components of intermediate-term memory: anesthesia-sensitive memory (ASM) and anesthesia-resistant memory (ARM). Recently, the anterior paired lateral (APL) neuron innervating the whole mushroom body (MB) has been shown to modulate ASM via gap-junctional communication in olfactory conditioning. Octopamine (OA), an invertebrate a...

Acute promyelocytic leukemia (APL), once described as the form of leukemia with the highest mortality, is now the most potentially curable subtype of adult acute myeloid leukemia. A brief review of the history of APL will describe the advances in research and clinical practice and their impact on patient outcomes. Oncology nurses should familiarize themselves with the nuances of APL because of ...

Objective: To explore the clinical characteristics of therapy-related acute promyelocytic leukaemia (t-APL) after Langerhans cell histiocytosis (LCH) in a paediatric patient. Method: The clinical manifestations and laboratory findings of a rare paediatric case were analysed and relevant literatures were reviewed. Result: A paediatric patient with LCH who had completed the whole chemotherapy was...
