Oral Copaiba Oil‐Resin Supplementation Reduces Plasma and Hepatic Oxidative Stress in Female and Male Hypothalamic‐Obese Animals

open access: yesFood Science &Nutrition, Volume 14, Issue 9, September 2026.
Oral supplementation with copaiba‐oil resin (Co‐resin) restores hepatic and plasma oxidative systems in hypothalamic‐obese male and female rats, therefore, it showed a more positive impact on females. This study highlights the therapeutic potential of Co‐resin to reduce reactive oxygen species production and restore plasma and hepatic antioxidant ...

Análise Comparativa de Resinas Compostas Convencionais e Resinas Bulk Fill

open access: yesARCHIVES OF HEALTH INVESTIGATION, 2023
Introdução: Durante a fotopolimerização da resina podem existir tensões de contração que possibilitam o surgimento de microtrincas/microfraturas, sensibilidade pós-operatória, desgaste superficial, cárie secundária, entre outros. Na intenção de encontrar a estética e as propriedades mecânicas e biológicas de uma restauração longeva, que surgiram as ...

Application of Principal Component Analysis and Probabilistic Neural Networks in Ferralsols Recovery Evaluation Through Planting of Mabea Fistulifera and Eucalyptus Urograndis

open access: yesLand Degradation &Development, Volume 37, Issue 13, Page 9021-9037, 15 August 2026.
ABSTRACT This study presents an innovative assessment model for analyzing the evolution of degraded soils subjected to different reclamation strategies. The proposal combines statistical and artificial intelligence tools to jointly integrate multiple physical and chemical soil properties, allowing for a more synthetic view of the processes.

Harnessing the PpHog1 Regulatory Network to Engineer a UPR‐Adaptive Komagataella phaffii Chassis for High‐Copy Secretory Protein Production

open access: yesMicrobial Biotechnology, Volume 19, Issue 7, July 2026.
Increasing gene copy number is a common strategy to boost heterologous expression, but an excessively high copy number of genes encoding secretory proteins can cause ER stress, leading to growth defects and ERAD activation. To solve this, we screened for key UPR signalling components in K. phaffii and used them to engineer a UPR‐Ad+ strain.

Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2966-2987, June 2026.
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...

Electrochemical Oxidation of Abietic and Dehydroabietic Acids for Sustainable Access to C‐7 and C‐15 Oxygenated Abietanes

open access: yesChemSusChem, Volume 19, Issue 9, 14 May 2026.
Batch and flow electrochemical methods enable direct C‐7 oxidation of abietic and dehydroabietic acids from colophony or their methyl derivatives to the corresponding ketones, while a mediated protocol enables additional C‐15 oxygenation, providing sustainable and selective routes to diversified abietane derivatives.

Impacts of Intercropping Maize–Grass–Legume for Silage Production and Oversowing Black Oat for Lamb Grazing on Soil Fertility

open access: yesGrass and Forage Science, Volume 81, Issue 2, April-June 2026.
ABSTRACT Intercropping grasses and legumes could be an important strategy for sustainable food production in tropical weathered soils. This study aimed to assess the impact of intercropping systems comprising maize and grass with or without a legume for silage production and overseeded black oat overseeded for lamb grazing on crop production, root ...
