Sunlight-mediated inactivation of microorganisms is a low-cost approach to disinfect drinking water and wastewater. The reactions involved are affected by a wide range of factors, and a lack of knowledge about their relative importance make it challenging ...
Attempts to create novel ligand-binding proteins often focus on formation of a binding pocket with shape complementarity against the desired ligand (particularly for compounds that lack distinct polar moieties). Although designed proteins often exhibit bin ...
Health-relevant microorganisms present in natural surface waters and engineered treatment systems that are exposed to sunlight can be inactivated by a complex set of interacting mechanisms. The net impact of sunlight depends on the solar spectral irradianc ...
N-Nitrosamines, in particular N-nitrosodimethylamine (NDMA), are carcinogens, which occur as chlorine disinfection by-products (DBPs) in swimming pools and hot tubs. UV treatment is a commonly used technique in swimming pools for disinfection and DBP atten ...
Ag loaded TiO2 was applied in the photocatalytic inactivation of Escherichia coil under ultraviolet (UV) and visible (Vis) light irradiations. Ag enhanced the TiO2 photodisinfecting effect under Vis irradiation promoting the formation of singlet oxygen and ...
Although the sunlight mediated inactivation of viruses has been recognized as an important process that controls surface water quality, the mechanisms of virus inactivation by sunlight are not yet clearly understood. We investigated the synergistic role of ...
This work investigates the occurrence frequency of days with high erythemal UV doses at three stations in Switzerland and Austria (Davos, Hoher Sonnblick and Vienna) for the time period 1974-2003. While several earlier studies have reported on increases in ...
Sterols and cholesterol in particular are lipids that have been studied exhaustively in view of their vital role in diverse cellular functions. Recently, it has been recognized that cholesterol is not only an essential component for the formation of membra ...
In a survey of cardiovascular risk factors in 185 men and 173 women of a Belgian population group, an independent and highly significant positive correlation was found between the serum concentrations of 25-hydroxyvitamin D3 and apolipoprotein A-I (p less ...
The seasonal variation of 25-hydroxycholecalciferol and 1,25-dihydroxycholecalciferol was analyzed in 240 elderly subjects (mean age: 78 yr) in Belgium. Serum 25-hydroxycholecalciferol was lowest from February until May (mean levels less than 25 nmol/L). S ...
