The design and synthesis of chem. probes to study and to elucidate complex biol. problems is becoming an increasingly important field in chem. We are interested in the repair of O6-alkylated guanines in DNA, a DNA lesion that results from alkylation by S-a ...
A new concept based on microstructuring techniques is presented to achieve size-dependent electrophoretic migration of DNA in free solution. Topographically structured microfluidic channels with periodical cavities in the range of the radius of gyration of ...
Monolayer adsorption of benzoic acid derivatives on activated oxide surfaces from solution and from the vapor phase are investigated with the view of modifying the work function of a conductive substrate. Para-substituted benzoic acids with a wide range of ...
The hydrochloride of (-)-(8R)-8-acetyl-7,8,9,10-tetrahydro-6, 8-dihydroxy-11-[3'-aminopropyloxy)methyl]naphthacene-5, 12-dione was derived from 1-(dimethaxymethyl)-2,3,5,6-tetramethylidene-7-oxabicyclo[2.2.2] heptane and shown to be a moderate intercalator ...
In a model of nude mice bearing a human colon carcinoma xenograft, the biodistribution and tumor localization of metatetrahydroxyphenylchlorin (m-THPC) coupled to polyethylene glycol (PEG) were compared with those of the free form of this photosensitizer u ...
Methylobacterium dichloromethanicum DM4 is able to grow with dichloromethane as the sole carbon and energy source by using a dichloromethane dehalogenase/glutathione S-transferase (GST) for the conversion of dichloromethane to formaldehyde. Mammalian homol ...
The ability to organize cells in three dimensions (3D) is an important component of tissue engineering. This study sought to develop an extracellular matrix (ECM) equivalent with a physicochemical structure capable of supporting neurite extension from prim ...
