Yeast-TiO<sub>2</sub> Biotemplate for Oxytetracycline Solar Photodecomposition

On the Photodecomposition of C10N0

As its major removal process the photodissociat ion of a tmospheric C 1 0 N 0 2 in the ultraviolet is discussed. It has repeatedly been pointed out that significance should be at t r ibuted to the pathways of chlorine nitrate fo rmat ion and its destruction since this compound might be involved in the ozone depletion mechanism through both the C10x and N O x a tmospheric cycles. This communica ...

Photodecomposition and Phototoxicity of Natural Retinoids

Sunlight is a known human carcinogen. Many cosmetics contain retinoid-based compounds, such as retinyl palmitate (RP), either to protect the skin or to stimulate skin responses that will correct skin damaged by sunlight. However, little is known about the photodecomposition of some retinoids and the toxicity of these retinoids and their sunlight-induced photodecomposition products on skin. Thus...

Photodecomposition of Water Catalyzed by Zr- and Ti-MCM-41

A physiologically based pharmacokinetic model for oxytetracycline residues in sheep.

A physiologically based pharmacokinetic model (PBPK) for oxytetracycline (OTC) residues in sheep was developed using previously published data from a combined serum pharmacokinetic and tissue residue study [Craigmill et al. (2000) J. Vet. Pharmacol. Ther.23, 345]. Physiological parameters for organ weights and tissue blood flows were obtained from the literature. The tissue/serum partition coef...

Biotemplate Synthesis of 3-nm Nickel and Cobalt Nanowires

Large biomolecules are attractive templates for the synthesis of metal1-7 and inorganic8-10 compound nanostructures. The well-defined chemical and structural heterogeneity of the biotemplates can be exploited for the precise control of the size and shape of the formed nanostructures. Here, we demonstrate that the central channel of the tobacco mosaic virus (TMV) can be used as a template to syn...
