Influence of Acrylonitrile Content on Processing, Morphology, Thermal Behavior, and Mechanical Properties of PA/NBR Thermoplastic Vulcanizates

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
Influence of acrylonitrile (ACN) content on the processing behavior and morphological development of PA/NBR thermoplastic vulcanizates. Torque‐time profiles, SEM, and SEM/AFM images show that an intermediate ACN level (38%) promotes improved phase dispersion and morphological uniformity, especially with increased processing time, resulting in the most ...

Associations between life‐course cognitive reserve and cognitive domains over 8 years in a large cohort of middle‐aged and older adults: The Brazilian Longitudinal Study of Adult Health (ELSA‐Brasil)

open access: yesAlzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract INTRODUCTION Cognitive reserve (CR) arises from cognitively enriching experiences over time and may buffer against cognitive decline. However, the mechanisms underlying CR in low‐ and middle‐income countries (LMICs) remain underexplored. This study investigated the latent structure of CR using socioeconomic and occupational indicators, and ...

Gonadulin and Insulin‐Like Growth Factor Involved in Rhipicephalus microplus Reproduction

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 3, Page 285-295, March 2026.
Insulin‐like growth factor (IGF2) in ovaries of Rhipicephalus microplus partially engorged females. Ovaries from females at different feeding stages were used to detect IGF2. ABSTRACT Gonadulin and insulin‐like growth factor (IGF) are neuropeptides synthesized by the central nervous system (CNS) of arthropods.
