A Multiscale Mechanistic Framework for Polydopamine Dyeing in Ultrablack Wool Textiles

Advanced Science, EarlyView.
Ultrablack photonic textiles are enabled through polydopamine (PDA) dyeing, which is governed by the interplay of PDA chemistry, wool surface topology and chemistry, and hierarchical fiber–yarn–fabric architecture. Fabric architecture emerges as a primary and previously underappreciated design lever for wide‐angle optical performance.

Encapsulated cell therapy for Parkinson`s disease: long-term, stable and efficacious targeting of the nigrostriatal dopaminergic system with GDNF

, 2015
Delivering glial cell line-derived neurotrophic factor (GDNF) to the CNS is a potential treatment for Parkinson’s Disease (PD). To be effective, GDNF needs to be delivered selectively in a long-term and stable manner to the nigrostriatal system.

Chronic Stress Promotes Gastric Cancer Metastasis by Inducing Microbiota‐Associated Kynurenine Accumulation and Macrophage Remodeling

Advanced Science, EarlyView.
Chronic stress reshapes the gut microbiota and enriches Lactobacillus reuteri, promoting microbiota‐associated kynurenine accumulation through altered tryptophan metabolism. Kynurenine drives immunosuppressive remodeling of tumor‐associated macrophages through TNFR2–C/EBPβ signaling, thereby enhancing gastric cancer dissemination.

Reference interval for urinary catecholamines and methylated catecholamines analysed using HPLC

, 2012
Catecholamines are stress hormones that are produced and released by a rare tumor called pheochromocytoma. This tumor can cause hypertension which if undiagnosed and untreated leads to death.

Cognitive Performance in Young Adults During Three Consecutive Days of Simulated Occupational Heat Stress: An Exploratory Study

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Global increases in occupational heat exposure are raising concerns about worker safety and cognitive performance during prolonged and repeated shifts. At present, the cumulative effects of repeated heat exposure on cognitive performance remain unclear.

Proto‐Panic Modulation by Caffeine‐Proteinoid Complexes

Journal of Applied Polymer Science, EarlyView.
Caffeine–proteinoid microspheres synthesized by thermal polymerization exhibit compartmentalized drug loading with encapsulation efficiencies of 61%–82% and triphasic release kinetics. Electrochemical monitoring reveals multi‐scale oscillatory dynamics consistent with chaotic and damped harmonic behavior, while Boolean logic operations demonstrate ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.
