Growth and differentiation signals mediated by different regions in the cytoplasmic domain of granulocyte-stimulating factor receptor. Touw IP: Distinct cytoplasmic regions of the human granulocyte colony-stimulating factor receptor involved in induction of proliferation and maturation.: The clonal proliferation of normal mouse hematopoietic cells: Enhancement and suppression by colony-stimulat...

abstract deviation or in other words committing a crime is literally a social problem. this research that was conducted in 1389 and 1390 has tried to investigate the causes of crimes committed by young male inmates qazvin central prison and effective variables on their tendency to deviation. accordingly after collecting theoretical framework and offering theoretical model including both hirsch...
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
The response of marrow stromal cells transformed with wild-type simian virus 40 to recombinant growth factors was examined. When transformed stromal cells were plated in semisolid medium without the addition of growth factors, only 0.4% of cells formed colonies while with the addition of recombinant factors such as interleukin 1 (IL-1) or tumor necrosis factor (TNF), up to 10% of the cells form...
Nine normal volunteers and 15 patients with pituitary disorders were given a combined test of anterior pituitary function using four hypothalamic releasing factors and arginine vasopressin. Rapid sequential intravenous infusions of human corticotrophin releasing factor 100 micrograms, growth hormone releasing factor 100 micrograms, luteinising hormone releasing hormone 100 micrograms, and thyro...
Human macrophage colony-stimulating factor (M-CSF) is a homodimeric cytokine that is a member of a structurally related family of hormones defined by an unusual up-up-down-down alpha-helical bundle. To identify regions on the surface of M-CSF that might interact with the M-CSF receptor, single and double amino acid substitutions were introduced into a truncated form of human M-CSF alpha by site...
Supernatants of cultured human thymic nonlymphoid cells were assayed for granulopoietic factors using cultures of low density bone marrow mononuclear cells (LD-BMMC). Thymic nonlymphoid cell-conditioned medium (TNLC-CM) supported vigorous myeloid colony growth of LD-BMMC. and of LD-BMMC depleted of T lymphocytes and/or monocytes. Colony stimulating activity (CSA) in TNLC-CM was abrogated by a h...
