Avaliação hemogasométrica, bioquímica e hematológica de ovinos suplementados com melão

open access: yes, 2015
This study evaluated the effects of two different amounts of melon on blood gas, biochemical and hematological variables of sheep not adapted. We used 12 cannulated sheep weighing 25 kg which never received concentrate.

Ouabain‐induced hypertension in rats: Mechanisms, variability and translational implications

open access: yesExperimental Physiology, EarlyView.
Abstract Ouabain‐induced hypertension is a multifactorial and condition‐dependent phenomenon involving coordinated actions across vascular, renal and central nervous system pathways. At the vascular level, ouabain inhibits Na⁺/K⁺‐ATPase, particularly the α2‐isoform, leading to elevated intracellular Ca2⁺, enhanced vasoconstriction and structural ...

The tasiR‐ARF pathway in plants: origin, functions, and interplay of miR‐390, tasiRNAs and ARF3

open access: yesPlant Biology, Volume 28, Issue 2, Page 328-344, March 2026.
Trans‐acting small interfering RNAs that silence a subset of Auxin Response Factors are crucial for plant growth, developmental timing, proper organ patterning, and coping with stress. Abstract Trans‐acting small interfering RNA (tasiRNAs) are a special type of endogenous small RNAs (sRNAs) found only in plants.

From Light‐Driven to Dark Synthesis: Streamlining Perfluoroalkyl Selenide Ether Formation

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 5, 7 February 2026.
Two orthogonal and user‐friendly protocols enable the efficient construction of (Se/S)RF bonds from simple dichalcogenides and perfluoroalkyl iodides. Visible‐light irradiation at 395 nm promotes seleno‐ and thioether formation, while a dark KOH/MeCN variant delivers selenoethers in minutes. Both approaches operate under mild, metal‐ and photocatalyst‐

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms

open access: yesFEBS Open Bio, Volume 16, Issue 2, Page 365-381, February 2026.
We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...

From Ink to Mockup: An Integrated Study of Historical Gall Ink Formulations and Their Impact on Paper

open access: yesChemPlusChem, Volume 91, Issue 2, February 2026.
Iron gall inks percipitates (right), and mockups upon artificial ageing (left) Iron gall inks (IGIs) played a central role as a writing medium in Western countries, leaving behind a vast legacy and significant conservation challenges. This study presents a twofold methodological approach to investigate the physicochemical behaviour of IGI‐based ...

Acute Toxicity and Genotoxicity of cMoL, a Lectin From Moringa oleifera Seeds With Antifungal Activity Against Cryptococcus Strains

open access: yesJournal of Applied Toxicology, Volume 46, Issue 2, Page 682-696, February 2026.
ABSTRACT Coagulant Moringa oleifera lectin (cMoL) is one of the compounds involved in the application of M. oleifera seeds for traditional water treatment methods. The present study highlights the new biotechnological potential of cMoL lectin as an antifungal agent against Cryptococcus neoformans B3501 and H99 and Cryptococcus gattii R265 strains ...

The Redox Properties of Polyphenols and Their Role in ROS Generation for Biomedical Applications

open access: yesAngewandte Chemie, Volume 138, Issue 3, 16 January 2026.
The dual redox nature of polyphenols enables antioxidant activity and controlled reactive oxygen species (ROS) generation. This review details the biomedical applications of polyphenols in materials such as nanoparticles, coatings, and hydrogels for antimicrobial, tissue regeneration, and cancer therapies.
