[Experience with percutaneous endoscopic gastrostomy in the nutrition of a patient with 3rd and 4th degree facial burns].

Recovery after thermal injury depends in great proportion on nutrition. A major problem is accounted in patients with facial burn, because they can not be nourished per vias naturales. Eliminating disadvantages of parenteral nutrition, but utilizing the advantages of enteral nutrition, we have tried a new method of treatment in a patient whose case is presented.

The gene encoding the elongation factor P protein is essential for viability and is required for protein synthesis.

Elongation factor P (EFP) is a protein that stimulates the peptidyltransferase activity of fully assembled 70 S prokaryotic ribosomes and enhances the synthesis of certain dipeptides initiated by N-formylmethionine. This reaction appears conserved throughout species and is promoted in eukaryotic cells by a homologous protein, eIF5A. Here we ask whether the Escherichia coli gene encoding EFP is essential for cell viability.

Structure of the chicken link protein gene: exons correlate with the protein domains.

The structure of the chicken link protein gene has been determined from a series of genomic clones that cover the entire coding region as well as the complete 3'-untranslated region and a small portion of the 5'-untranslated region. The gene is greater than 80 kilobase pairs long and is present in a single copy in the chicken genome. The link protein gene contains at least five exons with four encoding the entire protein.

Inactivation of pig muscle 3-phosphoglycerate kinase by thiol modification depends on reagent size.

Two thiol groups (out of the total seven) of pig muscle 3-phosphoglycerate kinase can be alkylated in 0.1 M Tris/Hcl buffer, pH 7.5, at 20 degrees C either with methyl iodide or with iodoacetamide in a second-order reaction with rate constants 0.
