Morphological and Morphometric Characterisation of Selected Camarodont Sea Urchin (Echinoidea: Camarodonta) Pedicellariae (Paracentrotus lividus, Psammechinus miliaris and Echinus esculentus)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Pedicellariae are small appendages on the surface of the echinoid test, involved in defence, cleaning, and locomotion. Pedicellariae in three species of camarodont sea urchins common in UK waters (Paracentrotus lividus [Lamarck, 1816], Psammechinus miliaris [P.L.S Müller, 1771] and Echinus esculentus [Linnaeus, 1758]) are the focus of this ...

Advances in Spatial Heterogeneity and Cellular Localization Specificity of Intratumoral Bacteria

open access: yesCancer Science, EarlyView.
Spatial localization of intratumoral bacteria governs their functional roles in tumor progression, metastasis, and treatment responses, with guiding significance for clinical management, as reviewed across three spatial paradigms. ABSTRACT Bacteria in tumors are increasingly recognized to be a part of the tumor microenvironment and their biological ...

Cleaning Efficacy and Surface Alterations of Titanium and Zirconia Implant Abutments Following Mechanical Instrumentation: An In Vitro Study

open access: yesClinical Oral Implants Research, EarlyView.
ABSTRACT Objectives To evaluate the cleaning efficacy, quantitative and qualitative surface modifications of titanium (Ti) and zirconia (Zr) abutments following instrumentation with twelve mechanical instrumentation modalities. Materials and Methods Twenty‐four Ti and twenty‐four Zr abutments were divided by marginal grooves into 36 test and 12 control

Reactive Red 195‐loaded halloysite for cotton dyeing and printing: Adsorption, characterisation and comparison with conventional exhaustion dyeing

open access: yesColoration Technology, EarlyView.
Abstract Textile wet processing generates dye‐containing effluents that require effective recovery and valorisation strategies. Halloysite nanoclay was used to capture Reactive Red 195 from a model aqueous solution, and the resulting dye‐loaded solid (REDHA7) was subsequently applied once to cotton by exhaustion dyeing and pigment‐type printing ...

Aptamer‐mediated outer membrane destabilization overcomes low permeability resistance in Pseudomonas aeruginosa

open access: yesThe FEBS Journal, EarlyView.
DNA aptamers, Apt 60 and Apt 173, target the BamA protein to compromise outer membrane integrity in Pseudomonas aeruginosa, making it susceptible to Azithromycin, an antibiotic that is otherwise poorly effective due to the low‐permeability membrane.

The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

open access: yesThe FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Structural and mutational analysis of Methanosarcina mazei prenylated FMN synthase reveals the basis of its unique prenyl donor substrate specificity

open access: yesThe FEBS Journal, EarlyView.
Some prenylated flavin mononucleotide (prFMN) synthases exceptionally prefer dimethylallyl phosphate (DMAP) over dimethylallyl diphosphate (DMAPP), which is a common prenyl donor substrate for many prenyltransferases. Structural and mutagenic analyses of Methanosarcina mazei prFMN synthase, which prefers DMAP but can also accept DMAPP, elucidated its ...

A live‐cell autophagy reporter reveals reversible vacuolation in naked mole‐rat skin fibroblasts under lysosomal stress

open access: yesThe FEBS Journal, EarlyView.
A tandem fluorescent mCherry–EGFP–LC3 reporter enables live‐cell visualisation of autophagy–lysosome dynamics in naked mole‐rat skin fibroblasts. Chloroquine‐induced lysosomal stress promotes accumulation of neutral LC3‐positive compartments and triggers pronounced LC3‐associated vacuolation.

The Agencies of the European Union: A Glimmer of Hope for Enlargement?

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract In recent years, the process of EU enlargement has become increasingly difficult. The longer the process drags on and the less likely accession appears, the more the candidate states are discouraged and the less influential the EU becomes. A different approach to integration must therefore be used.
