Nanocomposites containing poly(methyl methacrylate) (PMMA) and surface functionalized Multi-Walled Carbon Nanotubes (MWNTs) were synthesized. The dispersion of MWNTs in PMMA was characterized using Transmission Electron Microscopy (TEM).The synthesized nanocomposites were successfully foamed using a simple method based on the in-situ generation of supercritical carbon dioxide (CO2</sub...

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...

Consideration of embryo-derived growth factors, such as IGF1, is important when culturing an embryo in an in vitro fertilization (IVF) setting, or when studying the effect of growth factors on embryo development in vitro. Addition of IGF1 to the culture medium has been reported to cause a range of developmental responses in preimplantation mouse embryos. This variability may be due to culture o...

Phytohemagglutinin (PHA) is a lectin, obtained from the red kidney bean that binds to the membranes of T-cells and stimulates metabolic activity, cell division, etc. The object of this research was the comparison between self made PHA (Indigenous) and imported commercial one, following conventional and High Resolution Cell Synchronization technique (HRCS) .From each blood sample of healthy indi...

We studied mannose-containing glycopeptides and glycoproteins of subconfluent and confluent intestinal epithelial cells in culture. Cells were labelled with d-[2-(3)H]mannose for 24h and treated with Pronase or trypsin to release cell-surface components. The cell-surface and cell-residue fractions were then exhaustively digested with Pronase and the resulting glycopeptides were fractionated on ...

background: endometriosis is a common chronic inflammation which leads to infertility and chronic pelvic pain in affected women. secretory phospholipase a2 type iia (spla2iia) is an acute phase reactant that is markedly increased in inflammatory disorders. objective: to assess the effects of ω-3 and ω-6 polyunsaturated fatty acids (pufas) administration in endometrial cells culture on spla2iia ...

We have previously shown that cultured trunk neural crest cell populations irreversibly lose neurogenic ability when dispersal is prevented or delayed, while the ability to produce other crest derivatives is retained (Vogel, K. S. and Weston, J. A. (1988) Neuron 1, 569-577). Here, we show that when crest cells are prevented from dispersing, cell death is increased and neurogenesis is decreased ...
