Early Clinical and Cerebrospinal Fluid Predictors of 1‐Year Recurrence in Autoimmune GFAP Astrocytopathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Autoimmune glial fibrillary acidic protein astrocytopathy (GFAP‐A) is an inflammatory central nervous system disorder with variable outcomes. Relapse occurs in a subset of patients, but early predictors remain unclear. We aimed to identify admission‐available features associated with 1‐year recurrence and develop an interpretable ...

UvrY influences cAMP-CRP catabolite repression of luxS.

open access: yes, 2016
A) Expression of luxS::lacZ in SM1020 (ΔcyaA::kan luxS::lacZ) in the absence of cAMP and in the presence of 1 mM cAMP. (B) Expression of luxS::lacZ in SM1021 (ΔuvrY::cam ΔcyaA::kan luxS::lacZ) in the absence of cAMP, 1mM cAMP, and 5 mM cAMP. The point of

Full‐Field Damage Monitoring in Architected Lattices Using In situ Electrical Impedance Tomography

open access: yesAdvanced Functional Materials, EarlyView.
In situ electrical impedance tomography (EIT) turns 3D‐printed, CNT‐infused architected lattices into full‐field damage‐imaging systems. Tunable Voronoi‐based geometries act as active sensing architectures, enabling conductivity maps to detect early‐stage damage and localise sequential ligament fracture before catastrophic failure.

Autoinducer-2 plays a crucial role in gut colonization and probiotic functionality of Bifidobacterium breve UCC2003. [PDF]

open access: yesPLoS ONE, 2014
In the present study we show that luxS of Bifidobacterium breve UCC2003 is involved in the production of the interspecies signaling molecule autoinducer-2 (AI-2), and that this gene is essential for gastrointestinal colonization of a murine host, while ...

Biochemical Evaluation of SRH Analogs as Potential LuxS Inhibitors [PDF]

open access: yes, 2012
Quorum sensing in bacteria is a process of cell-to-cell communication facilitated by small molecules called autoinducers. Interspecies quorum sensing is facilitated by the autoinducer AI-2.

Guanosine‐Quadruplex Hydrogels as Dynamic, Mechanically Tunable and Ion Conductive 3D Scaffolds for Cell Culture Applications

open access: yesAdvanced Functional Materials, EarlyView.
Versatile guanosine‐quadruplex (GQ) hydrogels are developed as dynamic biomatrices for cell culture. These scaffolds are fabricated under mild aqueous conditions, present improved stability, tunable mechanical properties within physiological ranges; fibrillar, porous microstructure, ion conductivity, and cytocompatibility.

Deformation‐Tolerant Functional Elastomer Overlayers for Haze‐Assisted Light Extraction and Color Conversion in Stretchable Mechanoluminescent Films

open access: yesAdvanced Functional Materials, EarlyView.
Functional elastomer overlayers are integrated onto stretchable ZnS:Cu‐PDMS mechanoluminescent films to regulate light after emission without modifying the emissive composite. NLC‐PU provides haze‐assisted light extraction to enhance green mechanoluminescence, while DCM‐NLC‐PU combines green‐to‐yellow‐orange color conversion with enhanced outward light

Effect of LuxS/AI-2 Quorum Sensing System on Resistance of Lactobacillus plantarum to Environmental Stress(LuxS/AI-2群体感应系统对植物乳杆菌抵御环境胁迫的作用) [PDF]

open access: yesShipin kexue jishu xuebao
The LuxS/AI-2 quorum sensing (QS) system mediates intraspecific and interspecific signals of lactic acid bacteria, among which autoinducer-2 (AI-2) is crucial for probiotic activities of lactic acid bacteria, including environmental stress tolerance ...
