objective(s): in the current study antioxidant capacities of five different extracts of artemisia ciniformis aerial parts were evaluated by cell-free methods. then seven fractions of the potent extract were selected and their antioxidant capacity was assayed by cell free and cell based methods. materials andmethods: antioxidant ability was measured using the: 2, 2-diphenyl-1-picrylhydrazyl (dpp...
Background: Human FIX (hFIX) gene transfer into hepatocytes has provided a novel approach for treatment of hemophilia B. To obtain an improved expression of hFIX, the functional hFIX-expressing plasmids with appropriate intron-derived fragments which facilitate transcription and promote an efficient 3′-end formation of mRNAs are required.Objectives: We ai...
Abstract Successful initiation of the B-cell receptor (BCR) signaling, and subsequent antigen-encounter in germinal centers are both marked by sharp increases CD25 surface-expression. Likewise, oncogenic signaling leukemia (B-ALL) lymphoma induces CD25-surface expression. While is known as an IL2-receptor chain on T- NK-cells, significance its expression B-cells was unclear. We discovered that,...
background: patients with b-cell chronic lymphocytic leukemia (b-cll) have hetero-geneous clinical courses, thus several biological parameters need to be added to the cur-rent clinical staging systems to predict disease outcome. recent immunophenotypic stud-ies performed mainly in western populations have demonstrated the prognostic value of cd38 and zap-70 expression in b-cll. objectives: to i...
