Acid Activated Montmorillonite as Catalysts in Methyl Esterification Reactions of Lauric Acid

Journal of Oleo Science, 2012
The catalytic activity of acid activated montmorillonite in the esterification of free fatty acids (FFA) is reported. Standard Montmorillonite (MMT) type STx-1 provided by the Clay Mineral Society repository was activated using phosphoric, nitric and sulphuric acids under different conditions and the resulting materials were characterized and evaluated

Songorine inhibits mitophagy in chronic heart failure via the TBC1D15/Fis1/Rab7A pathway

British Journal of Pharmacology, EarlyView.
Abstract Background and purpose Songorine (SGR) is an alkaloid extracted from Aconitum carichaelii Debx. and has a demonstrated role in cardiac dysfunction. Chronic heart failure (CHF) is a severe clinical syndrome leading to functional impairment and death, primarily due to the deterioration of energy metabolism in cardiomyocytes. However, the precise

The antimicrobial activity of liposomal lauric acids against Propionibacterium acnes [PDF]

Biomaterials, 2009
This study evaluated the antimicrobial activity of lauric acid (LA) and its liposomal derivatives against Propionibacterium acnes (P. acnes), the bacterium that promotes inflammatory acne. First, the antimicrobial study of three free fatty acids (lauric acid, palmitic acid and oleic acid) demonstrated that LA gives the strongest bactericidal activity ...

Multiparasitism Resolves the Apparent Paradox of High Male Pheromone Investment Despite Frequent Within‐Host Mating in a Parasitoid

Entomologia Experimentalis et Applicata, EarlyView.
It is unknown why males of the parasitoid wasp Nasonia giraulti produce large amounts of a costly sex pheromone although they were long thought to mate with their females already before emergence within the host. Mated females do no longer respond to the pheromone.

Cosmetic creams with caprylic acid‐based Natural Eutectic Solvents: Stability, rheology and user perception

International Journal of Cosmetic Science, EarlyView.
By formulating creams with caprylic acid‐based hydrophobic Natural Eutectic Solvents and assessing their stability, rheological behaviour and sensory properties, this study demonstrates how these systems can act as multifunctional, COSMOS‐compliant ingredients that modulate emulsion characteristics without compromising formulation properties.
