Electroactive materials are increasingly being used in strategies to regenerate cardiac tissue. These materials, particularly those with electrical conductivity, are used to actively recreate the electromechanical nature of the cardiac tissue. In the present work, we describe a novel combination of poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)), a highly electroactive polymer, with graphene (G), exhibiting high electrical conductivity.

With the aim of replacing synthetic macromolecules by biological macromolecules for advanced applications, collagen films were produced with two different ionic liquids (ILs), choline dihydrogen phosphate ([Ch][DHP]) and choline serinate ([Ch][Seri]), added in order to modulate the electrical responses. The films were prepared by casting, varying IL content between 0 and 6 wt%. The morphology and thermal properties of the resulting films were found to be independent of both IL type and content.

Article Synopsis
  • Climate change is causing more variability in precipitation, especially in savanna environments, making drought tolerance crucial for improved plant genotypes.
  • The study focuses on comparing drought-tolerant Embrapa 48 and sensitive BR16, using an integrative approach of transcriptome, proteome, and metabolome analysis to uncover the mechanisms behind drought tolerance.
  • Key findings show that Embrapa 48 has better water absorption capabilities, and factors like altered root architecture and specific protein profiles play critical roles in enhancing drought tolerance, emphasizing the root system's importance over shoots in this process.

Current therapeutic ways adopted for the treatment of leishmaniasis are toxic and expensive including parasite resistance is a growing problem. Given this scenario, it is urgent to explore treatment alternatives for leishmaniasis. The aim of this study was to evaluate the effect of 3-phenyl-lawsone (3-PL) naphthoquinone on () infection, both and , using two local routes of administration: subcutaneous (higher dose) and tattoo (lower dose).
