From supramolecular vanadate receptors to enzyme models of vanadium Haloperoxidase [PDF]

open access: yes, 2005
V-HPOs are enzymes catalyzing the halogenation of a variety of organic substrates using hydrogen peroxide and halide ions at slightly acidic condition[1-3]. The X-ray structure of V-HPO from Curvularia inaequalis[4, 5] reveals that the positively charged

Engineering artificial metalloenzymes based on biotin-streptavidin technology for DNA recognition and asymmetric transfer hydrogenation catalysis [PDF]

open access: yes, 2012
: Metalloproteins occupy a central place among all proteins since they represent nearly half of all proteins in nature. Metalloenzymes catalyze important biological processes (photosynthesis, respiration, water oxidation) and other chemical reactions ...

Spatial variability of air pollutants in the Basel area and carcinogenic and non-carcinogenic health risk [PDF]

open access: yes, 2001
In environmental epidemiology, exposure assessment is a central topic as its quality determines in large part the validity of a study. Further, it is used in risk assessment to quantify the impact of environmental risk factors.

Advancing pharmacometrics in Africa—Transition from capacity development toward job creation

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 407-419, March 2025.
Abstract Trained pharmacometricians remain scarce in Africa due to limited training opportunities, lack of a pharmaceutical product development ecosystem, and emigration to high‐income countries. The Applied Pharmacometrics Training (APT) fellowship program was established to address these gaps and specifically foster job creation for talent retention.
