Acute promyelocytic leukemia (APL) is characterized by accumulation of apoptosis-resistant immature promyelocytic cells in the bone marrow and peripheral blood. We have shown that endoplasmic reticulum (ER)-associated degradation (ERAD) and protease-mediated degradation of misfolded nuclear receptor corepressor (N-CoR) confer resistance to unfolded protein response (UPR)-induced apoptosis in AP...

OBJECTIVE Previous studies have documented a high frequency of thrombotic events in lupus nephritis patients with antiphospholipid (aPL) antibodies in the serum, but there is little information on the impact of serum aPL antibodies on the clinical outcome of lupus nephritis. The aims of this study were to evaluate the seroprevalence of aPL antibodies in patients with lupus nephritis and assess ...

Chorea is a movement disorder which may be associated with immunologic diseases, in particular in the presence of antiphospholipid antibodies (aPL). Choreic movements have been linked to the isolated presence of plasmatic aPL, or to primary, or secondary antiphospholipid syndrome. The highest incidence of aPL-related chorea is detected in children and females. The presentation of chorea is usua...

A total of 97 acute promyelocytic leukemia (APL) patients with adequate flow cytometry (FC) data, bone marrow aspirates and presence of t(15;17)/PML-RARA by cytogenetics and/or FISH studies were analyzed for immunophenotypic pattern. Leukemic cells had the following phenotype: CD11b-, CD11c-, CD13+, CD33+, CD45+, CD64+/-, CD117+, and HLA-DR-. A subset of cases showed also an expression of CD2, ...

BACKGROUND/AIMS Antiphospholipid antibodies (aPL) have been detected in various proportions of patients with primary immune thrombocytopenia (ITP), but the clinical significance of this is debatable. The present study aimed to determine the frequency and clinical implications of elevated aPL in adult patients with ITP. METHODS We prospectively studied newly diagnosed adult patients with ITP w...

AIM OF THE STUDY The aim of the study was the assessment of changes in the glomerular filtration rate (GFR) during long-term observation in a group of systemic sclerosis (SSc) patients with and without chronic antiphospholipid (aPL) antibody positivity. MATERIAL AND METHODS The observation comprised 50 patients - 23 with diffuse cutaneous SSc - dcSSc and 27 limited cutaneous SSc - lcSSc. Afte...

BACKGROUND Acute promyelocytic leukemia (APL) is associated with chromosomal translocation t(15;17), which results in the proliferation of morphologically abnormal promyelocytes. Gain of supernumerary copies of the 8q24 chromosomal region, which harbors MYC and PVT1, has been shown to be the most common secondary alteration in human APL. Increased MYC can accelerate the development of myeloid l...

Programming languages have been increasingly mapping end-users needs and mental models. They have expanded the number of users who can program or learn how to program. They are focused on sighted users. This study introduces APL, an Audio Programming Language for blind learners. APL is a programming language with audio-based interfaces to assist blind learners to develop problem solving and alg...

Acute promyelocytic leukemia (APL) is a distinct subtype of acute myeloid (AML) mostly driven by the t(15;17) translocation that yields PML-RARα (PR) fusion protein. Apart from PML, other partner genes have been uncovered to fuse with RARα forming rare X-RARα genes. Among them, TBLR1-RARα (TR) novel oncogene induce APL identified in our previous studies, which elicited differed response and wor...

This study was performed to investigate the variations, dimensions and attachment of the abductor pollicis longus (APL) tendon. Fifty upper limbs of adult cadavers were dissected in the Faculty of Medicine, King Abdulaziz University, Jeddah, Saudi Arabia. Variations of APL tendon and its way of insertion were observed;its length, width and thickness were also measured and statistically analysed...
