Evaluation of Enzyme Inhibition and Kinetic Profiles of Origanum Essential Oils on Metabolic and Central Nervous System Targets

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
The essential oils of three Origanum species were chemically characterized and evaluated for their antioxidant and enzyme inhibitory activities. The different compositions confer selective bioactivities: O. vulgare exhibits good antioxidant and α‐glucosidase inhibitory activity, O. majorana shows promising tyrosinase inhibition, and O.

Bifurcation in the angular velocity of a circular disk propelled by symmetrically distributed camphor pills

open access: yes, 2019
We studied rotation of a disk propelled by a number of camphor pills symmetrically distributed at its edge. The disk was put on a water surface so that it could rotate around a vertical axis located at the disk center.

A Comprehensive Review of Waste‐Derived Materials for Solar Still Performance Enhancement

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.
Solar desalination reduces energy use and produces freshwater sustainably, but its productivity is limited and cannot meet rising demand. Thus, solar desalination system improvements are sought to boost water productivity. Waste materials are abundantly available and burden the environment, making them low‐cost enhancers for solar desalination systems.

Spectroscopy and Conformer‐Selective Photoelectron Circular Dichroism of Chiral Molecules

open access: yesChemistry – An Asian Journal, Volume 21, Issue 9, 14 May 2026.
Photoelectron circular dichroism (PECD) is a forward–backward asymmetry in the angular distribution of the electrons emitted by a chiral molecule ionized by a circularly polarized light (CPL). Its sensitivity to conformation is studied by one‐photon or resonance‐enhanced two‐photon ionization, the latter being conformer‐selective.

Renal and testicular up-regulation of pro-inflammatory chemokines (RANTES and CCL2) and cytokines (TNF-α, IL-1β, IL-6) following acute edible camphor administration is through activation of NF-kB in rats

open access: yesToxicology Reports, 2019
Camphor-induced oxidative stress and histopathological changes (in brain, lung, liver, kidney and testes) have been reported. We therefore investigated the effect of various doses of camphor in an acute study, on renal and testicular levels of some pro ...
