Beyond Core‐Periphery: A Multidimensional Typology of Brazilian Regional Inventive Capacity

Growth and Change, Volume 57, Issue 1, March 2026.
ABSTRACT The geography of invention in Brazil is characterized by a profound and multi‐polarised structure that extends beyond a simple core‐periphery dichotomy. This paper demonstrates this complexity through a multidimensional analysis of inventive capacity (2000–2023), operationalised along four axes—‘how much’, ‘who’, ‘how’, and ‘what’ is invented ...

Evaluation of the Therapeutic Potential of Bioactive Materials Based on a Complex of Oxidovanadium(IV) and Exopolysaccharide Levan in a Model of Insulin Resistance in Mice

ChemMedChem, Volume 21, Issue 4, 25 February 2026.
A low‐toxicity bioactive composition of oxidovanadium(IV) and exopolysaccharide levan is synthesized, characterized, and shown to reduce hyperglycemia, hypertriglyceridemia, and TyG index in a mice model of dexamethasone‐induced insulin resistance. Bioactive compositions containing vanadium complexes have been a viable strategy for constructing more ...
