Protoporphyrin IX (PpIX) is used as a fluorescence marker and photosensitizing agent in photodynamic therapy (PDT). A temporary increase of PpIX in tissues can be obtained by administration of 5-aminolevulinic acid (ALA). Lipophilicity is one of the key pa ...
The 2,2'-methylenebis[furan] (1) was converted to 1-{(4R,6S))-6-[(2R)-2,4-dihydroxybutyl]-2,2-dimethyl-1,3-dioxan-4-yl}-3- [(2R,4R)-tetrahydro-4,6-dihydroxy-2H-pyran-2-yl)propan-2-one ((+)-18) and its (4S)-epimer (-)-19 with high stereo- and enantioselecti ...
Renewed interest in the measurement of cellular K+ effluxes has been prompted by the observation that potassium plays an active and important role in numerous key cellular events, in particular cell necrosis and apoptosis. Although necrosis and apoptosis f ...
Neurotrophic factors hold promise for the treatment of neurodegenerative diseases. Intrathecal transplantation of polymer encapsulated cell lines genetically engineered to release neurotrophic factors provides a means to deliver them continuously behind th ...
An investigation of the mol. mechanism of the anticancer activity demonstrated by the ruthenium(II)-arene compd. [Ru(η6-p-cymene)Cl2(pta)] (pta is 1,3,5-triaza-7-phosphaadamantane), termed "RAPTA-C", in Ehrlich ascites carcinoma (EAC) bearing mice is descr ...
The intracellular fatty acid content of insulin-sensitive target tissues determines in part their insulin sensitivity. Uptake of fatty acids into cells is a controlled process determined in part by a regulated import/export system that is controlled at lea ...
A number of cyclo-β-tripeptides and their linear precursors were subjected to primary biol. evaluation for cancer-cell growth inhibition (one-dose, three-cell essay), and the five most active ones were then tested in the anti-tumor screen of the National C ...
Two cell lines, RTL-W1 and R1, from rainbow trout liver were used to investigate the effects of benzo[A]pyrene (BaP). BaP induced a catalytic measure of CYP1A, 7-ethoxyresorufin-O-deethylase (EROD) activity, in the rainbow trout liver cell line RTL-W1 but ...
Transforming growth factor-beta (TGF beta) is a potent immunosuppressive cytokine which inhibits the antigen (Ag)-dependent expansion of T cells both in vitro and in vivo by mechanisms not well defined yet. Here we report that exposure of interleukin (IL)- ...
The goal of this study was to compare growth characteristics of cells shed from a tumour with the native tumour cells. The human colon adenocarcinoma LS174T and its highly metastatic subline LS LiM 6 were grown as tissue-isolated tumours in nude mice and p ...
