Research Trends on Trace Element Contamination in Brazilian Urban Lentic Ecosystems: Environmental and Policy Drivers

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Lentic ecosystems are vulnerable to contamination by trace elements, which can accumulate and pose risks to aquatic life and human health. In a large, developing country such as Brazil, marked by vast geographic, environmental, and socioeconomic diversity, it is crucial to understand how these factors shape research on this group of ...

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 ...

Event‐Triggered Saturating Control for Synchronization of Lur'e Type Complex Dynamic Networks

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 4, Page 2184-2198, 10 March 2026.
ABSTRACT This article addresses the problem of synchronizing discrete‐time Lur'e type complex dynamic networks (CDNs) via dynamic event‐triggered control. In particular, it is considered that the control signal of each node is subject to input saturation. Using the Lyapunov Stability Theory, properties of slope‐restricted nonlinearities, and the linear

Double Salts and Racemate in Mefloquine–Ibuprofen and Mefloquine–Ketoprofen Systems. A Structural and Thermochemical Analysis

open access: yesChirality, Volume 38, Issue 3, March 2026.
(S)‐ibuprofen or ketoprofen were used to resolve mefloquine, forming double salts structurally similar to the racemic forms. ABSTRACT The formation of salts remains a highly sought‐after yet unpredictable strategy for resolving chiral drugs. Using a drug–drug approach, we have investigated the crystallization behavior of Mefloquine (Mf), a racemic ...

Upstream CB1R Regulation of β‐Adrenergic Memory Consolidation

open access: yesHippocampus, Volume 36, Issue 2, March 2026.
ABSTRACT Object recognition memory (ORM) plays a key role in identifying familiar items and encoding episodic information. ORM consolidation depends on β‐adrenergic receptor (βAR) signaling and is associated with increased BDNF expression in the dorsal hippocampus.

The Pubovesical Complex–Sparing Laparoscopic Radical Prostatectomy Improves Early Urinary Continence Without Compromising Oncologic Safety: A Prospective, Randomized, and Double‐Blinded Clinical Trial

open access: yesThe Prostate, Volume 86, Issue 4, Page 475-480, March 2026.
ABSTRACT Background Post‐prostatectomy urinary incontinence significantly impacts quality of life. Techniques that preserve periprostatic structures have shown promise in promoting earlier continence recovery, particularly with robotic‐assisted surgery.
