[Endocranial hypertension].

Introduction And Objective: The endocranial hypertension syndrome is one of the commonest and most feared neurological complications in clinical practice. This encourages its continued study, and is the subject of this review.

Development: Endocranial hypertension is the common pathway for the presentation of many neurological and non neurological disorders.

[Grouping of the genes of biosynthesis and resistance to beta-lactam antibiotics in cephamycin-C producing actinomycetes].

Three genes related to beta-lactam resistance have been found in the cluster of genes for cephamycin C biosynthesis in Nocardia lactamdurans. The cmcT gene encodes a hydrophobic protein located in the cytoplasmic membrane. The sequence of CMCT has a 21-31% identity in amino acids to proteins involved in antibiotic export from other antibiotic producing microorganisms.
