cancer stem cells (cscs) have been identified as rare cellular populations in many cancers, including leukemia and solid tumors. this minor subpopulation of cancerous cells is immortal tumor-initiating cells which thought to be responsible for cancer initiation, progression, metastasis, recurrence and drug/radiation resistance. low proliferative rate, high self-renewing capacity, differentiatio...

Murine bone marrow-derived macrophages, which measure 13.8 +/- 2.3 microns diameter in suspension, can ingest IgG-opsonized latex beads greater than 20 microns diameter. A precise assay has allowed the determination of the phagocytic capacity, and of physiological parameters that limit that capacity. Ingestion of beads larger than 15 microns diameter required IgG-opsonization, and took 30 minut...

It has been found that the capacity of lipoproteins for binding Mn(II) ions is dependent on the arrangement of the lipoprotein core. A change in the molecular organization of the LDL core (thermotropic transition) is associated with the change on the lipoprotein surface. In HDL there is no thermotropic transition and no abrupt change of the binding capacity. The observed surface-core correlatio...

We exhibit a possible road towards a strong converse for the quantum capacity of degradable channels. In particular, we show that all degradable channels obey what we call a “pretty strong” converse: When the code rate increases above the quantum capacity, the fidelity makes a discontinuous jump from 1 to at most 1 √ 2 , asymptotically. A similar result can be shown for the private (classical) ...

We report on a facile and robust method by which surface of electrospun cellulose acetate (CA) nanofibers can be chemically modified with cationic polymer brushes for DNA adsorption. The surface of CA nanofibers was functionalized by growing poly[(ar-vinylbenzyl)trimethylammonium chloride)] [poly(VBTAC)] brushes through a multi-step chemical sequence that ensures retention of mechanically robust...

Thrombospondin (TSP), a platelet alpha-granule protein, becomes expressed on the surface of thrombin-stimulated platelets. The surface expression of this protein occurs through two distinct mechanisms. At low platelet concentrations (1 X 10(8)/mL), a divalent ion-dependent, low-capacity mechanism predominates. At higher cell concentrations, a divalent ion-dependent, higher capacity mechanism pr...

This study investigates the feasibility of using ethylene oxide (EO) chain adsorption to determine the surface area of smectite in water. Experimental results indicate that high-molecular-weight poly(ethylene oxide) (PEO) should be used to provide reasonable estimations for monolayer capacity of PEO on smectite. The surface areas of smectites in water are calculated from the monolayer capacity ...

The U.S. joint military medical community has an increasing role in collaborative health sector engagement internationally as part of a whole of government approach to successful operations. The military must master the ability to catalyze health sector gains that can be developed by hosts, U.S. Government, and international agencies in both permissive environments and conflict zones. Capacity ...
