Localized surface plasmon resonances (LSPR) generated in a particle-film nanocavity enhance electric fields within nanoscale volume. LSPR can also decay into hot carriers, highly energetic species that catalyze photocatalytic reactions molecular analytes located close proximity to metal surfaces. In this study, we examined the intensity of field (near-field) and properties plasmonic nanocavitie...

in chronic myelogenous leukemia (cml), the mature granulocytes originate from a stem cell line harboring an abnormal chromosome, therefore it is possible that metabolic-functional abnormalities occur in the morphologically mature cells. in the present study, the phagocytic activity including intracellular killing, nitro blue tetrazolium (nbt) reduction, and phagocytosis were studied in 37 cml p...

the armadillo could be considered as an experimental model for leprosy studies. mycobacterium leprae main host cells are macrophages and schwann cells. however, endocytosis and germicidal activities of armadillo macrophages and monocytes have not yet been evaluated. the aim of this research was to evaluate endocytosis and nbt-reduction activities of monocyte-derived macrophages (mdm) and monocy...

To investigate the role of the G-CSF receptor (G-CSFR) in mediating the action of G-CSF, WEHI-3B D+ murine myelomonocytic leukemia cells were transfected with a plasmid containing the murine G-CSFR gene. Overexpression of G-CSFR in transfected clones was demonstrated by northern blotting, binding of [125I]rhG-CSF and cross-linking experiments. A high level of expression of the G-CSFR did not pr...

Fifteen phenolic compounds, including three caffeoyl derivatives, four gallotannins, three ellagitannins and five flavonoids, were isolated from an 80% MeOH extract of the leaves of Corylopsis coreana Uyeki (Korean winter hazel; CL). The anti-oxidative activities [1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity and xanthine oxidase superoxide scavenging activities (NBT)] and th...

objectives the current study aimed to investigate the immunostimulatory effects of the aqueous extract of heracleum persicum on mouse peritoneal macrophages. background the immune system provides protection against infectious diseases that are caused by various microorganisms, in particular pathogenic fungi. utilization of herbal immunostimulants is one solution to improve the immunity of human...

Generally, film dielectric materials often exhibit size-dependent structure and electric properties. In this work, we demonstrate a similar behavior in bulk Na0.5Bi0.5TiO3 (NBT)-based polycrystalline ceramics. According to the results from X-ray diffraction, (Na0.5Bi0.5)0.92Ba0.08Ti0.99Mg0.01O<sub...
