Synthesis of Naphthoquinones by Pd‐Catalyzed Heck–Matsuda Arylation of Lapachol

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Direct Heck–Matsuda arylation of lapachol enables the efficient synthesis of diverse naphthoquinones under homogeneous and heterogeneous palladium catalysis. The methodology features broad substrate scope, gram‐scale applicability, and provides a practical platform for quinone diversification.

Scn1a‐mediated developmental regulation of prefrontal cortex plasticity and cognition

open access: yesEpilepsia, EarlyView.
Abstract Objective The voltage‐gated sodium channel Nav1.1, encoded by Scn1a, is essential for γ‐aminobutyric acid (GABA)ergic function, and its alteration is associated with neurological disorders such as Dravet syndrome and Alzheimer's disease. We previously demonstrated that local Nav1.1 dysfunction in the medial prefrontal cortex (mPFC) during ...

Biological Effects of Selenium‐Containing Ionic Liquids: Cytotoxicity, Mercury Interaction, and Antiproliferative Activity in Glioblastoma Cells

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Selenium (Se) is an essential micronutrient that participates in redox regulation and cellular homeostasis. Selenium‐containing ionic liquids (ILsSe) have emerged as hybrid compounds combining the properties of organoselenium molecules with the tunable features of ionic liquids.

Exposure–Recovery Approach for Hepatic Toxicity Analysis of Pyrethroid Lambda‐Cyhalothrin: Histopathological, Histochemical, and Biochemical Responses in Oreochromis niloticus

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Lambda‐cyhalothrin is a synthetic pyrethroid insecticide widely used in agriculture, but its potential to contaminate aquatic ecosystems and exert high toxicity on fish at low concentrations raises ecotoxicological concerns. While standard histopathological and biochemical assessments are common, the novel integration of pigment‐based ...

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...
