new blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ecs) which in turn give rise to primitive capillary network. human cord blood (hcb) contains large subsets of mononuclear cells (mncs) that can be differentiated into endothelial-like cells in vitro. human mononuclear progenitor cells were purified from fresh umb...

an efficient synthesis of some novel coumarin derivatives via 1, 4- michael addition of indole to coumarin chalcones catalyzed by cellulose sulphonic acid (csa) under solvent free conditions is described. the corresponding michael addition products were obtained in good to excellent yield. the synthesized compounds were screened for their antibacterial activity against e. coli, s. aureus and an...

objective(s):micrornas (mirnas) are a class of short rnas that control the biological processes including cell proliferation, apoptosis and development. aberrant expression of mirnas was determined in the different stages of tumor development and metastasis. to study the effect of silibinin on mirnas expression, we evaluated quantitative expression of mir-21 and mir-155 as two oncomirs and seve...

innate lymphoid cells (ilcs) are identified as novel population of hematopoietic cells which protect the body by coordinating the innate immune response against a wide range of threats including infections, tissue damages and homeostatic disturbances. ilcs, particularly ilc2 cells, are found throughout the body including the brain. ilcs are morphologically similar to lymphocytes, express and re...

A guanidinato-stabilized binuclear yttrium carbyne complex [(PhCH 2 ) NC(NC 6 H 3 i Pr -2,6) ] Y (µ -Me)(AlMe 4 -CH) ( 1 was synthesized via C−H bond activation and its versatile reactivities were investigated. Complex underwent σ-bond metathesis with PhSSPh nucleophilic addition...

interleukin-12 (il-12) is a key cytokine involved in regulating the balance between th1 and th2 cells by promoting th1 response. a reduced capacity to produce this cytokine could lead to aberrant th2 development. on the same aspect significant impact of il-12 on invariant natural killer t (inkt) cells was reported. therefore, we examined the serum levels of il-12 and the absolute number of peri...
