The use of colony-stimulating factors became an autonomous approach in complex supportive care blood tumors. By indications granulocyte factor (G-CSF) it is possible to reduce neutropenic period, perform optimal timing therapy, decrease a number infection complications. development and active new G-CSF drug formulation – pegfilgrastim do not the duration period significantly, but reduced freque...

human granulocyte-colony stimulating factor (hg-csf) cdna was expressed in the methylotrophic yeast pichia pastoris under the control of the alcohol oxidase (aox1) promoter. an expression vector for hg-csf secretion was constructed using vector ppic9. higher levels of hg-csf was obtained using a p. pastoris mut+ (methanol utilization fast) phenotype. the effects of environmental factors such as...

Transforming growth factor betas are multifunctional polypeptides in the cytokine superfamily. They have a growth inhibitory role on hemopoietic progenitor cells in semisolid colony assay as well as in long-term bone-marrow culture. TGF - β2 represses stromal cells, stem cell factor gene transcription, and decreases the stability of c-kit transcripts in hemopoietic cells. TGF-β also modulat...

objective: embryonic cerebrospinal fluid (e-csf) has an important role in development of embryonic and adult brain. proteomic analysis suggests that this fluid has many morphogenes and cytokines that alter in time and space throughout embryonic life. the aim of this study was to evaluate the developmental effect of embryonic csf on proliferation and differentiation of neuroprogenitor cells in d...

Scaffolds derived from decellularized tissues provide a natural microenvironment for cell culture. Embryonic cerebrospinal fluid (e-CSF) contains factors which play vital roles in development of the nervous system. This research was aimed to survey the effect of Wistar rat e-CSF on neural differentiation of bone marrow derived mesenchymal stem cells (BM-MSCs) cultured on the human amniotic memb...

the human granulocyte-macrophage colony stimulation factor (hgm-csf) gene was cloned in the pet 23a( +) expression vector under the control of strong bacteriophage t7 transcription and translation signals. the hgm-csf gene was transferred into e. coli strainbl21 (de3)plyss andiptg was used for induction of gm-csf gene. production of the target protein was obtained as revealed by elisa and weste...

In this article, dynamics of the cerebrospinal fluid (CSF) was studied, using computational fluid dynamics. Using MRI images of two special cases, a 2-dimensional model of the ventricular system was made. CSF velocity and pressure distribution in ventricular system have high importance since the flow pattern of this liquid has an important effect on intracranial pressure, i.e., ICP, which has a...
