Recent studies have shown that soluble factors elaborated by human T lymphocytes enhance erythroid burst formation by human peripheral blood null cells. This study demonstrates that media conditioned by a long-term T lymphocyte line augmented the growth of erythroid colonies in vitro in the presence of erythropoietin (Ep). ATCC.CCl 119 (CCRF-CEM) was derived from a patient with ALL of T-lymphob...
We present an analytical model for nanoscale MOSFETs capable to describe the transition from drift-diffusion to ballistic transport. We start from a closed-form model of ballistic Fully Depleted SOI (FDSOI) and Double Gate (DG) MOSFETs with non degenerate statistics, and, on the basis of the Büttiker interpretation of dissipative transport in terms of virtual voltage probes, we show that a long...
Affinity chromatography has been applied to the problem of specifically removing luteinizing hormone from sera used to supplement tissue culture media. Horse or fetal calf sera, passed through a column of an anti-luteinizing hormone immunoglobulin fraction linked covalently to agarose, were specifically depleted in their content of luteinizing hormone as seen by radioimmunoassay and by their ef...
BACKGROUND/AIMS Bone marrow mesenchymal stem cells (MSCs) widely applied for treating myocardial infarction face survival challenges in the inflammatory and ischemia microenvironment of acute myocardial infarction. The study hypothesized that MSC-derived exosomes play a significant role in improving microenvironment after acute myocardial infarction and aimed to investigate the paracrine effect...
Human immunodeficiency virus type 1 (HIV-1)-infected individuals often exhibit multiple hematopoietic abnormalities reaching far beyond loss of CD4(+) lymphocytes. We used the SCID-hu (Thy/Liv) mouse (severe combined immunodeficient mouse transplanted with human fetal thymus and liver tissues), which provides an in vivo system whereby human pluripotent hematopoietic progenitor cells can be main...
A large, intracellular proteinase accumulated by inhibitors (PABI) was found in cultured mammalian cells as a large, multicatalytic proteinase with a greatly elevated concentration in the presence of small peptide proteinase inhibitors (Tsuji and Kurachi (1989) J. Biol. Chem. 264, 16093). Electron microscopic analysis showed that the tertiary structure of PABI highly resembled that of alpha 2-m...
Through immunologic means we have been able to separate primate bone marrow cells into populations containing late erythroid progenitors (colony forming units [CFUe] and e-clusters) but depleted of early erythroid progenitors (burst-forming units [BFUe]) or populations enriched in BFUe in relation to late progenitors. We used these fractionated populations in a two stage liquid/semisolid cultur...
I consider the class of “depleted pyrochlore” lattices of corner-sharing triangles, made by removing spins from a pyrochlore lattice such that every tetrahedron loses exactly one. Previously known examples are the “hyperkagome” and “kagome staircase”. I give criteria in terms of loops for whether a given depleted lattice can order analogous to the kagome “ √ 3× √ 3” state, and also show how the...
Abstract The small intestine of neonatal mice has abundant embryonically derived macrophages (MΦ) but only a subset remains into adulthood. These MΦ play role in fetal and development. In the intestine, they are juxtaposed to endothelial cells where facilitate postnatal vascular expansion. Postnatal recruitment bone-marrow-derived blood monocytes complicates identification study compartment sin...
the umbilical vein (uv) has a non pulsating and even pattern in normal fetuses. pulsation of uv has been described in severely growth restricted fetuses with chronic hypoxia. we wanted to see whether uv pulsations could also be seen in fetuses with heart deceleration during labor, as an adjunctive measure to assess the intra partum hypoxia. in a prospective study doppler examination was perform...
