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

Land 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

Microbial 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.

Análise Comparativa de Resinas Compostas Convencionais e Resinas Bulk Fill

ARCHIVES 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 ...

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

New 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 ...
