Effects of guanidine on synaptic transmission in the spinal cord of the frog [PDF]
The effects of guanidine on motoneurons of the isolated frog spinal cord were studied by adding the drug to the solution bathing the cord during intracellular recording. Guanidine (5·10–4 M) did not alter the membrane potential of motoneurons.

Lethal Mutagenesis of Picornaviruses with N-6-Modified Purine Nucleoside Analogues [PDF]
RNA viruses exhibit extraordinarily high mutation rates during genome replication. Nonnatural ribonucleosides that can increase the mutation rate of RNA viruses by acting as ambiguous substrates during replication have been explored as antiviral agents ...

Methionine 129 variant of human prion protein oligomerizes more rapidly than the valine 129 variant - Implications for disease susceptibility to Creutzfeldt-Jakob disease [PDF]
The human PrP gene (PRNP) has two common alleles that encode either methionine or valine at codon 129. This polymorphism modulates disease susceptibility and phenotype of human transmissible spongiform encyphalopathies, but the molecular mechanism by ...

The Core Histone-binding Region of the Murine Cytomegalovirus 89K Immediate Early Protein [PDF]
The gene regulatory immediate early protein, pp89, of murine cytomegalovirus interacts with both DNA-associated and isolated histones in vitro. We characterized the histone-binding region of pp89 and its cellular localization during cell division to ...
