Macrophages are known to depict two major phenotypes: classically activated macrophages (M1), associated with high production of pro-inflammatory cytokines, and alternatively (M2), which present an anti-inflammatory function. A precise control over M1-M2 polarization is a promising strategy in therapeutics modulate both tissue regeneration tumor progression processes. However, this not simple task as behave differently depending on the microenvironment. In agreement this, non-consistent data...
Abstract Water pollution affects all living habitats, since it is the most basic element that sustains life forms and, as an exceptional solvent, readily makes any compound available for cells, either nutrients or noxious substances. Elimination of molecular contaminants from water quality one challenging technical problems conventional treatments like flocculation and filtration fail short to defeat. Particulate photocatalysts, used degrade contaminants, have main drawback their recovery...
