background: acute myeloid leukemia (aml) is an immunophenotypically heterogeneous malignant disease, in which cd34 positivity is associated with poor prognosis. osteopontin (opn) plays different roles in physiologic and pathologic conditions like: survival, metastasis and cell protection from cytotoxic and apoptotic stimuli. due to anti-apoptotic effect of opn in normal and malignant cells, sil...
the aim of present study was to investigate the effect of individual and co-inoculation of trichoderma species and arbuscular mycorrhizal fungi (amf) on growth, mycorrhization, population of trichoderma, and wilt disease severity in pigeon pea (cajanus cajan l millsp). three species of trichoderma, namely, t. harzianum (th), t. virens (tr), and t. viride (tv) and consortium of amf (myc; mixture...
conclusion these data show that the identified gene encoded tet resistance gene as mfs–type multi-substrate efflux transporter, which contributes to intrinsic resistance on range of structurally unrelated compounds in salmonella species. background tetracyclines (tcs) are a type of broad-spectrum bacteriostatic antibiotics used for treatment of a wide variety of infections. these antibiotics ev...
we consider of the antimicrobial activity on the ag nanoparticles(ag nps) aqueous solutions, which was prepared using a stabilizer, such as poly(n vinyl 2 pyrrolidone pvp , for staphylococcus aureus) s aureus and escherichia coli e coli by measuring the minimum inhibitory concentration mic . antimicrobial effect of ag nps for s aureus and e coli was investigated using disk diffusion method also...
Erratum Unfortunately, the original version of this article [1] contained an error. There are two references in the text to the threshold for defining VAP as greater than 10^4 colony forming units/ml. These should read greater OR EQUAL to 10^4 colony forming units/ml. The error is in the abstract and in the intervention sections. In the abstract, please replace: Patients with clinically suspect...
conclusions flushing dental unit waterlines are an effective measure in reducing the number of bacterial contaminants. results bacterial contamination was found in all 24 units at the beginning of daily activity with a mean colony count of 17850. the number of colonies decreased to 3250 following 30 seconds of flushing in 16 units and later to 1837 after flushing for two minutes in 13 units. in...
objective: the present study examines the effects of increased heat shock proteins expression in mda-mb468 adeno-carcinoma cells on expansion and differentiation of hematopoetic stem cells from human umbilical cord blood. materials and methods: highly purified human cd34+ cells (magnetic bead isolation) derived from umbilical cord blood were cultured, under three conditions, in the presence of ...
Methodological development of a clonogenic assay to determine endothelial progenitor cell potential.
The precise and conceptual insight of circulating endothelial progenitor cell (EPC) kinetics is hampered by the absence of an assay system capable of evaluating the EPC differentiation cascade. An assay system for EPC colony formation was developed to delineate circulating EPC differentiation. EPC colony-forming assay using semisolid medium and single or bulk CD133(+) cells from umbilical cord ...
