These data suggest that tumor growth and malignancy is associated with a change in the enzymatic source of NO from calcium-independent NOS to calcium-dependent NOS isoform in primary localization. These data suggest that the inhibition of calcium-independent NOS activity in early stages and/or inhibition of calcium-dependent NOS activity in later stages could delay growth of solid tumors.

Tracking the evolution of research in waste recycling science (WRS) can be valuable for environmental agencies, as well as for recycling businesses. Maps of science are visual, easily readable representations of the cognitive structure of a branch of science, a particular area of research or the global spectrum of scientific production. They are generally built upon evidence collected from reliable sources of information, such as patent and scientific publication databases. This study uses the methodology developed by to make a "double overlay map" of WRS upon a basemap reflecting the cognitive structure of all journal-published science, for the years 2005 and 2010. The analysis has taken into account the cognitive areas where WRS articles are published and the areas from where it takes its intellectual nourishing, paying special attention to the growing trends of the key areas. Interpretation of results lead to the conclusion that extraction of energy from waste will probably be an important research topic in the future, along with developments in general chemistry and chemical engineering oriented to the recovery of valuable materials from waste. Agricultural and material sciences, together with the combined economics, politics and geography field, are areas with which WRS shows a relevant and ever increasing cognitive relationship.

ObjectivesTo assess the efficacy and safety of fluocinolone acetonide 0.025% otic solution versus placebo in treating patients with otic eczema.MethodsIn this multicentre, randomized, double-blind, parallel-group phase 3 clinical trial, conducted at 12 Spanish centres between March 2012 and March 2013, patients received fluocinolone acetonide 0.025% or placebo otic solution twice daily for 7 days (days 1–7) with an 8-day follow-up (days 9–15). Outcome measures included change in itching from baseline (day 1) to study days 4–8 and 9–15, and change in otoscopic signs (erythema, oedema, and scaling) from baseline to the end of treatment (day 8) and end of follow-up (day 15).ResultsPatients treated with fluocinolone acetonide 0.025% (n = 66), as compared with placebo-treated patients (n = 69), showed significantly higher reductions in itching from baseline to study days 4–8 and 9–15, and in individual and global otoscopic signs from baseline to the end of treatment (day 8) and end of follow-up (day 15). Incidence and severity of adverse events was similar between the fluocinolone and placebo groups.ConclusionsFluocinolone acetonide 0.025% otic solution, administered twice daily for 7 days, is an effective and safe treatment for otic eczema.
