Reaction of [Pd(1R,2R-diaminocyclohexane)Cl(2)] with the oxidised form of the tripeptide glutathione ([gamma]-l-glutamyl-l-cysteinyl-glycine) in aqueous solution leads to reductive cleavage of the disulfide bond.
We report a new and improved method to prepare, by gentle hydration of lipid films, oil-free giant unilamellar vesicles (GUVs), in which enzymatic reactions can be encapsulated. The traditional method of gentle hydration requires very low concentrations of metal ions, whereas enzymatic reactions generally require mono- and divalent metal ions at physiological concentrations. In order to improve...
Analyses of cellular processes in the yeast Saccharomyces cerevisiae rely primarily upon a small number of highly domesticated laboratory strains, leaving the extensive natural genetic diversity of the model organism largely unexplored and unexploited. We asked if this diversity could be used to enrich our understanding of basic biological processes. As a test case, we examined a simple trait: ...
The effect of free muramyl tripeptide phosphatidylethanolamide (MTPPE) and liposome-encapsulated MTPPE (LE-MTPPE) on Klebsiella pneumoniae septicemia resulting from intraperitoneal bacterial inoculation was investigated in mice. When administering a single prophylactic dose at 24 h before bacterial inoculation, the percentage survival was 55% (MTPPE) or 40% (LE-MTPPE), whereas untreated control...
Two randomized, double-blind clinical trials in dogs with spontaneous appendicular osteosarcoma treated with combination chemoimmunotherapy are reported. In both trials, dogs without overt metastasis underwent complete amputation of the affected limb. In trial 1, 40 dogs were treated with cisplatin chemotherapy [(CDDP), 70 mg/m2 i.v. every 28 days x 4]. Following CDDP, dogs without evidence of ...
