It is proposed that catalysis by minerals and metal ions had a central role in the steps that led to the origins of life. In particular, the formation of biopolymers in the presence of water requires catalysis to compete with hydrolytic reactions. Catalysi ...
The reaction of d,l-5'-activated nucleotide of adenosine in the presence and absence of montmorillonite gave 60:40 and 96:4 ratios, resp. of the d,d- and l,l:d,l- and l,d-dimers. [on SciFinder (R)] ...
The phospholipid topology of the outer membrane of intact rat liver mitochondria and derived outer membrane vesicles was investigated by determining the accessible pool of the various phospholipid classes towards phospholipase A2, a phosphatidylcholine-spe ...
While the existence of cholesterol/sphingolipid (raft) membrane domains in the plasma membrane is now supported by strong experimental evidence, the structure of these domains, their size, their dynamics, and their molecular composition remain to be unders ...
The consequence of reduced uptake of neurotransmitters into synaptic vesicles on synaptic transmission was examined in rat hippocampal slices and culture using bafilomycin A1 (Baf), a potent and specific blocker of the vacuolar-type (V-type) ATPase, which ...
A new strategy for the reversible formation of supported lipid bilayers is introduced. It uses an extension of immobilized metal ion affinity chromatog. technol., which depends on the reversible formation of complexes between metal ion binding chelator gro ...
A well accepted technique to ensure reliability in a distributed system is to replicate every object which performs critical processing. However, it is not easy to achieve replication, i.e to enable a replicated object to communicate with other objects, ju ...
A simple method has been developed for the prodn. of Au surfaces which are uniformly flat over large areas. Si wafers serve as substrates for the evapn. of thin Au layers. A glass slide glued onto the Au film allows successful sepn. of the Au layer from th ...
A simple oil/water/surfactant model is used to study self-assembly of surfactants. The model contains only the most obvious elements: oil and water do not mix; a surfactant is an amphiphilic mol. with one side hydrophilic and the other hydrophobic. Comput ...
We present a method that allows the on-demand release and mixing of zepto- to femtoliter vols. of solns. in the interior of vesicular nanoreactors. The reactors comprise a nested system of lipid vesicles, part of which release their cargo in the interior o ...
