Impact of daratumumab on stem cell mobilization and collection, engraftment and early post-transplant complications among multiple myeloma patients undergoing autologous stem cell transplantation.

Autologous stem cell transplantation (ASCT) remains a standard therapy for multiple myeloma (MM) patients. Our study aimed to assess the impact of daratumumab-containing induction on stem cell (SC) mobilization, apheresis and hospitalization. We evaluated 200 newly diagnosed MM patients that were mobilized for SC collection and which received induction with ( = 40) or without daratumumab ( = 160).

Capillary electrophoresis in biochemical and clinical laboratoriesp selected attractive examples.

As demonstrated by selected examples from our laboratories, CE is a unique methodology for purity control of synthetic as well as natural tissue-isolated biopolymers, a prerequisite before reliable biotestings should be performed. A combination of rapid matrix-assisted laser desorption ionization mass and CE electrophoretic mobility determinations facilitates primary sequence determinations of enzymatic peptide digest mixtures often making costly Edman degradations unnecessary. The enormous separation efficiency and large variety of different possible separation modes in CE, allow detection of single components in complex mixtures which is demonstrated by the apolipoprotein A-I determination in human blood serum in this communication.

Radioimmunoassays for the C-terminus of prothymosin alpha and the N-terminus of parathymosin alpha for the measurement of the levels of alpha-thymosins in human cancer.

A radioimmunoassay specific for the C-terminus of human prothymosin alpha was developed using the synthetic peptide [Cys-Aca degrees]-human prothymosin alpha (90-109)-OH coupled to KLH as antigen and the analogue [Tyr-Aca degrees]-human prothymosin alpha (90-109)-OH labelled with 125I as tracer. The radioimmunoassay measured intact prothymosin alpha, in the range of 2-100 pmol and does not cross-react with the partly homologous polypeptide parathymosin alpha. A major epitope was located in the segment 95-107.

Esterases in quail (Coturnix coturnix). Physicochemical and developmental aspects.

1. Soluble esterases of digestive system organs of various developmental stages in the quail (Coturnix coturnix) were resolved by polyacrylamide gel electrophoresis into several molecular forms which were characterized as carboxylesterases, acetylesterases, cholinesterases and esterases sensitive to eserine. 2.

Expression of alpha-thymosins in human tissues in normal and abnormal growth.

Radioimmunoassays specific for the N and C termini of human prothymosin alpha and the N terminus of human parathymosin alpha were employed for the measurement of the levels of alpha-thymosins in human thymus, spleen, and liver during normal growth and intestine and breast in malignant growth. A differential expression of the two alpha-thymosins was observed in thymus (prothymosin alpha-rich) and liver (parathymosin alpha-rich). A decline in the levels of both alpha-thymosins was found with age, with prothymosin alpha in thymus showing the sharpest change (15- to 30-fold).
