The Effect of Neonatal Administration of Sex Hormones on Ribonucleic Acid Metabolism in the Liver of Male and Female Rats
Fifteen minutes after the intraperitoneal injection of 32P labelled phosphate, normal adult male rats show a higher incorporation of isotope into their liver nuclear RNA than do females. A single injection of tes...

Beeinflussung der calorigenen Wirkung von sympathomimetischen Aminen durch Lithium
The influence of lithium on the oxygen uptake and the calorigenic actions of norepinephrine (NE), isoprenaline, amphetamine, and 2,4-dinitrophenol (DNP) was studied in rats. The metabolic rate of animals which...

Morphology and ultrastructure of the antenna of male Periplaneta americana as related to chemoreception
On the antenna of adult male Periplaneta americana, three size ranges of classical sensilla basiconica were found. Based on SEM, a sensillum of the s. trichodeum shape was revealed, but our TEM efforts indicate t...

Partial trisomy of the long arm of human chromosome 1 as demonstrated by in situ hybridization with 5S ribosomal RNA
In a newborn boy with multiple malformations, a tandem duplication was detected at the distal end of the long arm of one human chromosome 1. The Giemsa bands, 1q31 to 1q43–44, were repeated serially. Since 5S ...
