Is pure red cell aplasia (PRCA) a clonal disorder?

Published: May 1993

Pure red cell aplasia (PRCA) is an uncommon disorder, many cases lacking a well defined aetiology. This report describes three cases of PRCA (two idiopathic and one associated with B-CLL) who were investigated to assess the possibility of their PRCA being associated with a clonal proliferation of T-lymphocytes. The results show that one patient had evidence of T-cell receptor (TCR) gamma chain rearrangement, and the other had a TCR delta chain rearrangement. These two cases raise the possibility of PRCA being associated with a clonal proliferation of T-cells and further studies are warranted.

Pure red cell aplasia (PRCA) is a rare complication of erythropoietin (EPO) therapy, characterized by a severe deficiency in red blood cell production. There is no guideline on the treatment for PRCA because there have been too few cases to perform prospective cohort studies. The main treatments for PRCA include immediate cessation of EPO, restrictive transfusion, and immunosuppressive therapies.

The exploration of pure organic ultra-long room temperature phosphorescence (RTP) materials has emerged as a research hotspot in recent years. Herein, a simple strategy for fabricating long-afterglow polymer aerogels with three-dimensional ordered structures and environmental monitoring capabilities is proposed. Based on the non-covalent interactions between pectin (PC) and melamine formaldehyde (MF), a composite aerogel (PCMF@phenanthrene) (PCMF@PA) doped with phosphorescent organic small molecules was constructed.

The development of pure-green organic emitters with ideal emission peak and ultra-narrow full-widths at half-maximum (FWHMs) remains a formidable challenge. Herein, we report two new green emitters, CNBN and MCNBN, which achieve extremely narrow FWHMs by synergistic rigid π-extension and cyano-substitution for sky-blue multi-resonance thermally activated delayed fluorescence (MR-TADF) core. The introduction of cyano groups induces red-shifts of emission to green region and dramatically minimize the FWHMs.

Fiber Bragg gratings (FBGs) inscribed by UV light and different femtosecond laser techniques (phase mask, point-by-point, and plane-by-plane) were exposed-in several irradiation cycles-to accumulated high doses of gamma rays (up to 124 MGy) and neutron fluence (8.7 × 10/cm) in a research-grade nuclear reactor. The FBG peak wavelengths were measured continuously in order to monitor radiation-induced shifts.

Generation of upscaled quantities of human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM), for therapeutic or testing applications, is both expensive and time-consuming. Herein, a scalable bioprocess for hiPSC-CM expansion in stirred-tank bioreactors (STB) is developed. By combining the continuous activation of the Wnt pathway, through perfusion of CHIR99021, within a mild hypoxia environment, the expansion of hiPSC-CM as aggregates is maximized, reaching 4 billion of pure hiPSC-CM in 2L STB.
