Ruthenium(II) Polypyridyl Complexes Containing COUBPY Ligands as Potent Photosensitizers for the Efficient Phototherapy of Hypoxic Tumors
Hypoxia, a hallmark of many solid tumors, is linked to increased cancer aggressiveness, metastasis, and resistance to conventional therapies, leading to poor patient outcomes. This challenges the efficiency of photodynamic ...
Antimicrobial efficacy of solar disinfection in cellulose fiber supported photoactive materials
According to the World Health Organization, antimicrobial resistance is one of the emerging threats to global health. Therefore, the development of new strategies to mitigate resistant bacterial strains is highly desirable. ...
A POCIS-based approach for the monitoring of pharmaceuticals in wastewater treatment plants: Calibration and deployment challenges
The impact of pharmaceuticals in aquatic environments requires complementary monitoring techniques to the more conventional grab sampling approach for an improved sample representativity. This study explores the application ...
The Masking Game: Design of Activatable Antibodies and Mimetics for Selective Therapeutics and Cell Control
The high selectivity and affinity of antibody binding havemade antibodies all-pervasive tools in therapy, diagnosis, and basic science.A plethora of chemogenetic approaches has been devised to makeantibodies responsive to ...
QUICKSERV: a service quality assessment tool for the quick-service restaurant industry
Purpose The purpose of this study is to empirically develop and validate a practical, consistent and specific scale to assess perceived service quality at the service encounter at quick-service restaurants (QSRs). De ...
Measuring the provincial supply of higher education institutions in China
This paper proposes and estimates three novel higher education indices for 31 Chinese provinces: i) the Chinese Higher Education Density Index (CHEDI) to analyze the evolution of the quantitative distribution of higher ...

Neuropsychopharmacology of Emerging Drugs of Abuse: meta- and para-Halogen-Ring-Substituted α-PVP (“flakka”) Derivatives
Changes in the molecular structure of synthetic cathinones has led to an increase in the number of novel emerging drugs in the illicit drug market at an unprecedented rate. Unfortunately, little is known about the ...
Versatile, elastomeric and degradable polyHIPEs of poly(glycerol sebacate)-methacrylate and their application in vascular graft tissue-engineering
Polymer scaffolds are an important enabling technology in tissue engineering. A wide range of manufacturing techniques have been developed to produce these scaffolds, including porogen leaching, phase separation, gas ...
Biomineralization in Three-Dimensional Scaffolds Based on Bacterial Nanocellulose for Bone Tissue Engineering: Feature Characterization and Stem Cell Differentiation
Bacterial nanocellulose (BNC) has a negative surface charge in physiological environments, which allows the adsorption of calcium ions to initiate the nucleation of different calcium phosphate phases. The aim of this study ...
Residues of Deltamethrin in Pine Needles and Pine Nuts of Catalonia (Spain)
In recent years, recurrent droughts have weakened stone pine (Pinus pinea) forests and facilitated the emergence of harmful pests and diseases, including the Leptoglossus occidentalis. The production of stone pine nuts has ...
Auditor-provided tax services and tax avoidance: evidence from Spain
We investigate the relationship between auditor-provided tax services (APTS) and tax avoidance in Spain. As a result of a recently enacted EU legislation, APTS is seriously restricted within the EU. The evidence available ...
