[Glucose tolerance test in children of diabetic mothers. Evaluation from birth to twelve years of age (author's transl)]. | Twenty-five children born of 23 diabetic mothers, 17 of whom were treated with insulin, underwent glucose tolerance tests with estimation of blood insulin levels. These tests were performed on a regular basis before the age of five years, then every two years. Blood glucose and insulin disturbances were slight but appe... | 634,760 | [

Sequence arrangement of the 16S and 26S rRNA genes in the pathogenic haemoflagellate Leishmania donovani. | Kinetic and chemical analysis show that the haploid genome of Leishmania donovani has between 4.6 and 6.5 X 10(7) Kb pairs of DNA. Cot analysis shows that the genome contains 12% rapidly reassociating DNA, U3% middle repetitive DNA with an average reiteration frequency of 77 and 62% single copy DNA.

Flow requirements in the Hafnia modifications of the Mapleson circuits during spontaneous respiration. | The Mapleson A, B, C and D circuits can be changed into non-polluting circuits by employing continuous gas evacuation directly from the circuit, via an ejector flowmeter (Jørgensen 1974); Mapleson A and C circuits with this modification have been described previously as the Hafnia A and C circuits (Christensen 1976, Th... | 636,803 | [
