Purification and characterization of a novel thermoacidophilic and thermostable α-mannosidase from the digestive fluid of oil palm weevil Rhynchophorus palmarum (Coleoptera: Curculionidae) larvae

European Journal of Entomology, 2009
An extracellular α-mannosidase with unusual properties was purified from the digestive fluid of oil palm weevil (Rhynchophorus palmarum Linnaeus) larvae using ammonium sulphate saturation, size exclusion and anion-exchange chromatography.

Lithium Diisopropylamide‐Mediated Ring‐Opening of Tetrahydrofuran in the Synthesis of Polyhydroxylated Indolizidines

European Journal of Organic Chemistry, EarlyView.
Chiral tri‐ and pentahydroxy spirocyclopentane‐indolizidines were synthesized using lithium diisopropylamide “LDA” promoted diallylation and tetrahydrofuran “THF” ring‐opening in a one‐pot procedure as a key step. The sequence leading to the targeted hydroxy‐spiroindolizidines was achieved by cis‐dihydroxylation followed by reduction of the enamine and

Proteomic signatures of equine dental tooth tissues in ageing and disease

Equine Veterinary Journal, EarlyView.
Abstract Background Ageing and dental disease in horses lead to structural and functional deterioration of dental tissues, yet their molecular signatures remain poorly characterised. Understanding how these processes alter the protein composition of enamel, dentin, cementum and pulp is essential for improving equine oral health and identifying ...

Lysosomal alpha-D-mannosidase.

Bioscience reports, 1999
Alpha-mannosidosis in the human is an autosomal recessive lysosomal storage disease caused by a deficiency of lysosomal alpha-D-mannosidasea activity. Lysosomal alpha-D-mannosidase is involved in the catabolism of N-linked glycoproteins through the sequential degradation of high-mannose, hybrid and complex oligosaccharides.

Identification and functional characterization of a highly divergent N-acetylglucosaminyltransferase I (TbGnTI) in Trypanosoma brucei [PDF]

, 2014
Trypanosoma brucei expresses a diverse repertoire of N-glycans, ranging from oligomannose and paucimannose structures to exceptionally large complex N-glycans.

The N‐Glycome to Differentiate Mesenchymal Stem Cells Upon Chondrogenic Differentiation, Dedifferentiation, and Senescence

PROTEOMICS, EarlyView.
ABSTRACT Mesenchymal stem cells (MSCs) are adult stem cells able to self‐renewal or differentiation into different cell types, including chondrocytes. N‐Glycans are post‐translational modifications of glycoproteins that contribute to vital cell functions.

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

Pest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was
