Chemical Profile and Antibacterial Activity of Cymbopogon Citratus Leaf Essential Oil

ChemistrySelect, Volume 11, Issue 29, 3 August 2026.
The essential oil of Cymbopogon citratus was chemically characterized by GC–MS and evaluated for antibacterial activity against clinically relevant Gram‐positive and Gram‐negative bacteria. Citral isomers (geranial and neral) were identified as the major constituents, and the oil exhibited selective bactericidal and bacteriostatic effects, supporting ...

High‐Throughput Glucose Biosensing Using Jack Bean [Canavalia ensiformis (L.) DC.] Lectin as Electrochemical Signaling Element

Electroanalysis, Volume 38, Issue 4, April 2026.
An electrochemical biosensor employing Canavalia ensiformis lectin immobilized on a Prussian Blue‐modified glassy carbon electrode was developed for label‐free glucose detection at submicromolar levels. The integration of lectin biorecognition with the conductive Prussian Blue layer ensured stable and selective signal transduction.

CASPR2 Autoimmune Antibodies Induce Neuronal Hyperactivity in Human Brain Organoids

Journal of Neurochemistry, Volume 170, Issue 2, February 2026.
Maternal antibodies targeting CASPR2 are a known risk factor for neurodevelopmental disorders, yet their impact on early human brain development remains unclear. We modeled this exposure using human neural organoids treated with patient‐derived CASPR2 antibodies up to the age of 6 months.

Behavioral profile predicts ethanol preference in adolescent mice, but not in adults: A machine learning approach

Alcohol, Clinical and Experimental Research, Volume 50, Issue 1, January 2026.
The present study reveals that adolescent behavioral phenotypes strongly predict ethanol preference in mice, while no predictive patterns emerged in adulthood. Machine learning analysis identified sucrose preference as a positive predictor and sociability as a negative predictor of alcohol intake, highlighting natural reward sensitivity and social ...

Density cardinals

Journal of the London Mathematical Society, Volume 112, Issue 3, September 2025.
Abstract How many permutations are needed so that every infinite–coinfinite set of natural numbers with asymptotic density can be rearranged to no longer have the same density? We prove that the density number dd${\mathfrak {dd}}$, which answers this question, is equal to the least size of a nonmeager set of reals, non(M)${\mathsf {non}}({\mathcal {M}})
