Safety and efficacy of a feed additive consisting of methyl salicylate [09.749] obtained from the leaves of Gaultheria procumbens L. for use in all animal species except cats (FEFANA asbl)

open access: yesEFSA Journal, Volume 24, Issue 10, October 2026.
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of methyl salicylate [09.749] obtained by steam distillation from the leaves of Gaultheria procumbens L. when used as a sensory additive in feed for all animal species except cats.

Fluoride solvation-the case of the missing ion [PDF]

open access: yes, 1991
The thermodynamics of fluoride ion solvation in nonaqueous and mixed aqueous solvents are reviewed. Gibbs energies of transfer , ∆tG⁰ (F -) H20-s , indicate that the solvation of the fluoride ion is dominated by hydrogen bonding.

π‐Extended Silyl Enolates as Emerging Platforms in Radical Chemistry

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 36, 24 September 2026.
This review covers the emerging role of π‐extended silyl polyenol ethers in radical chemistry. It highlights their versatile roles as electron‐rich SOMOphiles, silyl radical cation precursors, and nucleophilic partners in radical–polar crossover manifolds, while considering recent advances in photoredox catalysis, electrochemistry, and transition metal‐

Nucleophilic Trifluoromethoxylation of Acyl Chlorides: A Direct Route to Trifluoromethyl Esters

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 18, 19 September 2026.
A new method for the synthesis of the underexplored trifluoromethyl carboxylic esters using acyl chlorides as readily available feedstocks and in situ‐generated AgOCF3 from silver fluoride and the trifluoromethyl para‐toluenesulfonate has been designed. The reaction works on a large variety of aromatic and aliphatic acyl chlorides, while minimizing the

Recent Applications of Propylene Carbonate as a Solvent in Sustainable Organic Synthesis

open access: yesChemSusChem, Volume 19, Issue 17, 14 September 2026.
This review evaluates propylene carbonate (PC) as a non‐toxic green solvent in organic synthesis, highlighting its performance in key reactions including cross‐couplings, asymmetric hydrogenations, peptide synthesis and biocatalysis. Across these processes, PC delivers yields comparable to conventional and alternative green solvents.

THE RELATIONSHIP BETWEEN THE LEVELS OF THE FLUORIDE ION AND THE THYROID HORMONES IN GOATS WITH FLUOROSIS

open access: yes, 2017
In the present study, 104 goats with endemic fluorosis, living at the foot of the mountains Agri (Mount Ararat) and Tendurek, were compared with 30 healthy goats to investigate the relationship between the plasma levels of the fluoride ion (F) and the ...

Chronic effects of fluoride in Tuj sheep on serum levels of total protein, albumin, uric acid, and nitric oxide and activities of lactate dehydrogenase and leucine aminopeptidase

open access: yes, 2005
Twenty healthy yearling Tuj ewe-lambs with a mean body weight of 31 2 kg were divided into two equal groups. Each group of ten sheep was provided with hay and water ad libitum throughout the study.

MILD CHRONIC NaF INTAKE PROMOTES INSULIN RESISTANCE AND INCREASE IN INFLAMMATORY SIGNALING IN THE WHITE ADIPOSE TISSUE OF RATS

open access: yes, 2019
Excessive fluoride intake is associated with systemic metabolic alterations similar to those observed in type 2 diabetes such as decreased insulin secretion, impaired glycemic control, and insulin resistance.
