CONTEXT Skin cancer is a preventable and commonly diagnosed cancer in the U.S. Excessive ultraviolet radiation exposure is a known cause of skin cancer. This article presents updated results of two types of interventions evaluated in a previously published Community Guide systematic review: multicomponent community-wide interventions and mass media interventions when used alone. EVIDENCE ACQU...

This work concerns the synthesis of poly(pyrazolopyridine)s via a three-component Hantzsch reaction. The first part this study was intended to determine adequate experimental conditions for an analytically pure pyrazolopyridine heterocycle model compound in quantitative yield, which can be further used polymer synthesis. For purpose, effect different parameters (solvent, temperature, additive) ...

An efficient and environmentally benign one-pot condensation of cyclic diketones, aldehydes naphthols was achieved with 1,4-diazabicyclo[2-2-2]octane supported on Amberlyst-15 as a novel catalyst, producing variety benzoxanthenones in good to excellent yields. The advantages this multicomponent reaction include the use heterogeneous solventless conditions simple methodology that is atom-economi...

a set of multicomponent perovskite oxide nanoparticles based on la1-xsrxco1-yfeyo3-δ(lscf) were prepared by a simple chemical precipitation method for application in low temperature solid oxide fuel cells (lt-sofc) as cathode materials.  the precursor materials used in this synthesis were lanthanum nitrate hexahydrate [la(no3)3.6h2o], strontium nitrate [sr(no3)2], cobalt nitrate hexahydrate [co...
