[Measuring the length of newborn infants].

Since 1985, measurement of the length of neonates has been practically abandoned in the Netherlands because it was thought that stretching the legs and knees briefly in order to measure the length immediately after birth could be harmful for the development of the hip joint. However, this fear seems unjustified. Measuring the length of the neonate provides useful information regarding the general condition and has predictive value for the final adult height.

Mechanism of high-copy-number integration of pMIRY-type vectors into the ribosomal DNA of Saccharomyces cerevisiae.

Targeted integration of the yeast plasmid pMIRY2 into the ribosomal DNA (rDNA) of Saccharomyces cerevisiae by homologous recombination results in transformants carrying 100-200 copies of the plasmid per cell which are stably maintained over a large number of generations [Lopes et al., Gene 79 (1989) 199-206]. These properties make pMIRY2 an attractive vector for high-level production of (heterologous) proteins by yeast cells.
