Primary Oral Myiasis: A Case Report

Myiasis commonly refers to invasion of live human or animal tissue by fly larvae of the Diptera order where they complete their cycle totally or in part, feeding on living or dead tissue, as well as on body fluids. Infestation of tissues of vertebrate species is pandemic but more frequently found in tropical and subtropical countries where poor hygiene, poor housing infrastructure, warm humid climate, and proximity with domestic animals prevail. Its diagnosis is made basically by the presence of larvae. The present paper reports a case of gingival myiasis involving 14–16 larvae in a 12-year-old boy

Poly(ethylene glycol)-Based Ionic Liquids: Properties and Uses as Alternative Solvents in Organic Synthesis and Catalysis

International audience: PEG-based ionic liquids are a new appealing group of solvents making the link between two distinct but very similar fluids: ionic liquids and poly(ethylene glycol)s. They find applications across a range of innumerable disciplines in science, technology, and engineering. In the last years, the possibility to use these as alternative solvents for organic synthesis and catalysis has been increasingly explored. This Review highlights strategies for their synthesis, their physical properties (critical point, glass transition temperature, density, rheological properties), and their application in reactions catalyzed by metals (such as Pd, Cu, W, or Rh) or as organic solvent (for example for multicomponent reactions, organocatalysis, CO2 transformation) with special emphasis on their toxicity, environmental impact, and biodegradability. These aspects, very often neglected, need to be considered in addition to the green criteria usually considered to establish ecofriendly processes
