CYP3A5 genetic variability influences sildenafil and metabolite in pulmonary hypertension
British Journal of Clinical Pharmacology, EarlyView.Aim Interindividual variability in sildenafil response among pulmonary hypertension patients (PH) may be influenced by CYP3A5 polymorphisms. CYP3A5*3 allele reduces CYP3A5 activity and affects sildenafil metabolism. This study investigated the associations between CYP3A5 genotype and plasma concentrations of sildenafil and N‐desmethyl sildenafil, as ...

Removal of PAHs from n-Paraffin by Modified Clinoptilolite [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2007 The ability of natural clinoptilolite and its modified forms were studied for removal of PAHs from n-paraffin. Surfactant modified zeolite (SMZ) was obtained by modifying clinoptilolite with hexadecyltrimethylammonium ion. Homoionic forms of zeolite were

Biotechnology and Bioengineering, EarlyView.ABSTRACT To increase the information content in early stages of bioprocess development, various technologies have been introduced for monitoring cultivations in microtiter plates (MTPs). Besides spectroscopical measurements, like in the BioLector technology, optical measurements with luminescent sensors, placed directly in the cultivation medium ...

Carbon Energy, EarlyView.This study shows that lithium induces Li–Ni–O/Ni heterostructures on biochar, creating oxygen vacancies and optimal acid–base environments that enhance steam activation and suppress carbon deposition. These interfacial effects and synergistic modulation lead to high hydrogen yields at moderate temperatures, providing a scalable catalyst design strategy

Carbon Energy, EarlyView.A confinement‐derived bubbling effect strategy is used for controllable synthesis of biomass‐derived 2D carbon nanoweb with ultra‐thin longitudinal dimensions (1.5−2.5 nm) and high surface area (2055 m2 g−1). Its ultra‐thin 2D nanoweb structure enhances rate capability and cycling stability at high charge–discharge rates and in high‐mass‐loading ...

Novel approaches to determination of PAHs and halogenated POPs in canned fish
Czech Journal of Food Sciences, 2011 A simple method is described for simultaneous isolation of 7 indicator polychlorinated biphenyls (PCBs), 10 polybrominated diphenyl ethers (PBDEs), 22 organochlorine pesticides (OCPs), and 16 polycyclic aromatic hydrocarbons (16 EU PAHs).
