Chemical structure and antioxidant activity of a new exopolysaccharide produced from Micrococcus luteus

Journal of Genetic Engineering and Biotechnology, 2014
An exopolysaccharide (EPS) reaching a maximum of 13 g/L was isolated from Micrococcus luteus by ethanol precipitation. The crude EPS was purified by chromatography on DEAE-cellulose and Sephacryl S-200, affording a polysaccharide active fraction (AEP ...

Loss-of-function mutations in UDP-Glucose 6-Dehydrogenase cause recessive developmental epileptic encephalopathy

Nature Communications, 2020
UDP-glucuronic acid is a component of the extracellular matrix. Here, the authors report biallelic variants in the gene encoding UDP-Glucose 6-Dehydrogenase (UGDH) in individuals affected by developmental epileptic encephalopathies that impair UGDH ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

Insect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

The FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

Characterization of dermatan sulfate and chondroitin sulfate profiles during brain regeneration in Styela plicata

The FEBS Journal, EarlyView.
Adult ascidians are capable of regenerating their entire brains following injury, and glycosaminoglycans have been shown to either promote or inhibit neuritogenesis. In this study, dermatan 2,6‐disulfate (D2,6S) was identified as the predominant complex carbohydrate in the ascidian brain.

Dichloro (bis[diphenylthiourea]) cadmium complex as a precursor for HDA-capped CdS nanoparticles and their solubility in water

South African Journal of Science, 2010
A single-source precursor route has been explored by using the diphenylthiourea cadmium complex as the source of cadmium sulphide (CdS) nanoparticles. The reaction was carried out using hexadecylamine (HDA) as the solvent and stabilising agent for the ...

Methyl and Benzyl (Ethyl 3,4-di-O-benzyl-2-O-benzoyl-1-thio-β-d-glucopyranosyl)uronate

Molbank
Methyl and benzyl (ethyl 3,4-di-O-benzyl-2-O-benzoyl-1-thio-β-D-glucopyranosyl)uronate were synthesised from a protected thioglycoside in three steps. A regioselective ring opening of the benzylidene acetal with BH3.THF generated C6-OH material, which ...

Penetration enhancement effects of topically applied crosslinked hyaluronic acid

International Journal of Cosmetic Science, EarlyView.
Cross‐linked hyaluronic acid (HA) was demonstrated to enhance the topical delivery of a variety of hydrophilic actives into the skin. This phenomenon was observed for both small molecules and macromolecules, the latter of which was analysed with MALDI mass spectrometry imaging (MALDI‐MSI).

Isolation and Identification of Erysipelothrix sp. in Hybrid Grouper (Epinephelus fuscoguttatus × E. lanceolatus) in Taiwan

Journal of Fish Diseases, EarlyView.
ABSTRACT In February 2025, a mortality event of unknown aetiology occurred at a hybrid grouper (Epinephelus fuscoguttatus × Epinephelus lanceolatus) aquaculture farm in southern Taiwan, with sporadic daily deaths persisting for a month. Four moribund groupers were collected over three sampling intervals for diagnostic investigation.
