Anti-arthritic and anti-inflammatory activity of linalool against formaldehyde and complete Freund's adjuvant induced arthritis in rats.

Arthritis, characterized by persistent joint inflammation, poses a significant challenge due to its detrimental effects on cartilage function and subchondral bone health. This study investigates the potential pharmacological effects of linalool, a monoterpene alcohol commonly found in essential oils, as a promising treatment for arthritis. In vitro assays, including red blood cell membrane stability and protein denaturation tests, were conducted to preliminarily assess the anti-arthritic potential of linalool.

Impacts of atmospheric turbulence on optic measurements over heterogeneous flat terrain: insights from large eddy simulations.

Atmospheric refraction imposes a fundamental limitation on the accuracy and precision of geodetic measurements that utilize electromagnetic waves. For terrestrial observations at optical wavelengths recorded over flat terrain, the vertical temperature gradient controls the bending of the rays thus affecting mostly the vertical angle measurement. The rules of thumb for mitigating these effects (variation ranges and short-term fluctuations) are based on intuition and practitioner experience.

Measuring trade costs and analyzing the determinants of trade growth between Cambodia and major trading partners: 1993-2019.

High trade costs pose substantial barriers to the process of trade liberalization. This study aims to measure trade costs and explore the driving forces behind the growth of bilateral trade between Cambodia and its top 30 trading partners from 1993 to 2019. Using a micro-founded measure of trade costs derived from the gravity model, we find that Cambodia's average trade costs decreased by 35.

Soluble guanylyl cyclase, the NO-receptor, regulates endothelium-dependent vascular relaxation via its transnitrosation activity.

We previously demonstrated that the NO-receptor soluble guanylyl cyclase (GC1) has the ability to transnitrosate other proteins in a reaction that involves, in some cases, oxidized Thioredoxin 1 (oTrx1). This transnitrosation cascade was established and we identified by mass spectrometry and mutational analysis Cys 610 (C610) of GC1 α-subunit as a major donor of S-nitrosothiols (SNO). To assay the relevance of GC1 transnitrosation under physiological conditions and in oxidative pathologies, we studied a knock-in mouse in which C610 was replaced with a serine (KI αC ) under basal or angiotensin II (Ang II)-treated conditions.

Inhibitory Peptide of Soluble Guanylyl Cyclase/Trx1 Interface Blunts the Dual Redox Signaling Functions of the Complex.

Soluble guanylyl cyclase (GC1) and oxido-reductase thioredoxin (Trx1) form a complex that mediates two NO signaling pathways as a function of the redox state of cells. Under physiological conditions, reduced Trx1 (rTrx1) supports the canonical NO-GC1-cGMP pathway by protecting GC1 activity from thiol oxidation. Under oxidative stress, the NO-cGMP pathway is disrupted by the S-nitrosation of GC1 (addition of a NO group to a cysteine).
