A study of the behaviour of some substituted 1,2,4-triazoline-3-thiones in different media [PDF]

open access: yesJournal of the Serbian Chemical Society, 2000
The acid-base behaviour of 4-phenyl-5-(4-R-benzyl)-1,2,4-triazoline-3-thione (1(R = OH); 2(R = OC2H5)) was studied in aqueous sulfuric acid and sodium hydroxide solutions.

Intensified processes for FAME production from waste cooking oil: a technological review [PDF]

open access: yes, 2013
This article reviews the intensification of fatty acid methyl esters (FAME) production from waste cooking oil (WCO) using innovative process equipment. In particular, it addresses the intensification of WCO feedstock transformation by transesterification,

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Matrix-filler interactions in a co-ground ecocomposite: surface properties and behaviour in water [PDF]

open access: yes, 2011
Ecocomposites made up of polystyrene and starch were produced by co-grinding. The mechanism by which the composite is formed was identified by following the particle size and morphology.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Fütterungsbedingte Alkalose: ein Problem für die Tiergesundheit? Fallbericht aus einem Biobetrieb [PDF]

open access: yes, 2007
The acid-base equilibrium is of vital importance for living organisms. Its shifts affect practically all life processes, thus resulting in decreased milk production, sterility, etc. which may cause economic losses.
