Purpose: The aim of the study was to understand how nano-influencers deal with managing their image with a view to achieving authenticity. Method: This research used a qualitative approach, with data constructed through semi-structured interviews and analyzed based on Thematic Analysis. Results: We recognized that the main objective of nano-influencers is to build their reputation, so that they develop organic and structuring content strategies that enhance their naturalness, expertise and accessibility. By reinforcing their authenticity, these nano-influencers have creative control over the content they develop, externalizing their identities and generating congruence between message and sender. The invasion of brands in their profiles, therefore, is minimal, so that they can be justified by the influencers' passion for the products, aiding a coherent construction of narratives. Theorical contributions: We found that nano-influencers develop a fairytale authenticity when analysing their endorsements of brands. However, by exposing their own brand, that is, the services they offer, the human brand that they are, these SMIs seek absolute authenticity, based on transparency and organicity, similarity and inseparability. This is a considerable advance in the literature, as we identified that the paths of authenticity can be different from the stakeholder it is aimed at (brands or followers). Originality/relevance: We proposed a theoretical model consisting of five elements that characterize the image management of nano-influencers. This is an unprecedented research movement to identify the constructs that form image management. We believe that such elements are guiding motives for the actions of SMIs, and we propose that variations in the types of influencers will affect the characteristics contained in these elements.

Moringa oleifera Lam. seeds contain lectins that exhibit interesting bioactive properties, but their effects on metabolic syndrome (MetS) remain poorly understood. This work evaluated the effects of the water-soluble lectin from M. oleifera seeds (WSMoL) on metabolic, inflammatory, and histopathological alterations in a mouse model of MetS-like features. Male Swiss mice were fed a high-fat diet plus condensed milk solution for 11 weeks. Animals then received phosphate-buffered saline (negative control), orlistat (40 mg/kg), or WSMoL (1, 2, or 4 mg/kg, i.p.) for 14 days. A healthy group (Sham) received standard chow. The MetS-like protocol induced obesity, hyperglycemia, dyslipidemia, visceral adiposity, and systemic inflammation. WSMoL improved metabolic parameters at all doses, reducing visceral fat, attenuating hyperglycemia, and improving the lipid profile. It also decreased pro-inflammatory cytokines (IL-2, IFN-γ, TNF-α, and IL-6) while increasing IL-10 levels. WSMoL prevented hepatic steatosis and renal lipid accumulation, although inflammatory and degenerative tissue changes persisted. The 4 mg/kg dose showed efficacy but was associated with elevated AST and more frequent inflammatory alterations. In conclusion, WSMoL mitigated key features of MetS-like condition, although incomplete tissue recovery and signs of organ stress at the highest dose warrant caution regarding its potential therapeutic use.
