Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Genetic and morphological diversity in Armeria (Plumbaginaceae) is shaped by glacial cycles in Mediterranean refugia

open access: yesAnales del Jardín Botánico de Madrid, 2011
Little is known of the direct effects of Quaternary glaciationdeglaciation cycles in plants within southern European refugia. This study, centered in the Sierra Nevada (S Spain), used RAPD and morphometric data from 36 populations of Armeria ...

Tumor‐stromal crosstalk and macrophage enrichment are associated with chemotherapy response in bladder cancer

open access: yesFEBS Open Bio, EarlyView.
Chemoresistance in bladder cancer: Macrophage recruitment associated with CXCL1, CXCL5 and CXCL8 expression is characteristic of Gemcitabine/Cisplatin (Gem/Cis) Non‐Responder tumors (right side) while Responder tumors did not show substantial tumor‐stromal crosstalk (left side). All biological icons are attributed to Bioicons: carcinoma, cancerous‐cell‐

Morphometric study of a hybrid zone between Armeria beirana and A. pubigera (Plumbaginaceae) in the Northwest of the Iberian Peninsula

open access: yesAnales del Jardín Botánico de Madrid, 2007
Several hybrid populations between Armeria beirana Franco and A. pubigera (Desf.) Boiss. have been studied in a hybrid zone located in Carnota (A Coruña, Spain) along a coastal stretch approximately 3 km long.

A spin-dependent local moment approach to the Anderson impurity model

open access: yes, 2007
We present an extension of the local moment approach to the Anderson impurity model with spin-dependent hybridization. By employing the two-self-energy description, as originally proposed by Logan and co-workers, we applied the symmetry restoration ...

Meta‐analysis fails to show any correlation between protein abundance and ubiquitination changes

open access: yesFEBS Open Bio, EarlyView.
We analyzed over 50 published proteomics datasets to explore the relationship between protein levels and ubiquitination changes across multiple experimental conditions and biological systems. Although ubiquitination is often associated with protein degradation, our analysis shows that changes in ubiquitination do not globally correlate with changes in ...

Topological protection of bound states against the hybridization

open access: yes, 2012
Topological invariants are conventionally known to be responsible for protection of extended states against disorder. A prominent example is the presence of topologically protected extended-states in two-dimensional (2D) quantum Hall systems as well as ...

Association of CDKN2A/B Homozygous Deletion and Extent of Resection With Survival of Patients With WHO CNS5 Grade 4 Astrocytoma

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives WHO grade 4 astrocytomas are associated with poor prognosis, and their prognostic factors remain controversial. This study aimed to identify the prognostic factors and develop a management algorithm for these patients. Methods This study retrospectively included 151 CNS5 adult grade 4 astrocytomas from two medical centers.
