Erythropoietic response to isomeres of triiodothyronine

Zusammenfassung Verabreichung vond-, wie auch vonl-Triiodothyrosin erzeugt eine ähnliche Vermehrung der Erythropoiesis in nephroektomierten Ratten, wie bei der Messung der Radioeiseninkorporation durch Erythrozyten (18 h nach Injektion von radioaktivem Eisencitrat). Es ergab sich weiter, dassd- undl-Thyrosin, im Unterschied zu Erythropoieten, die reticulozytose Eisenassimilation in vitro vermehrte. Danach scheinen verschiedene Mechanismen bei der Stimulation der Erythropoiesis durch Erythropoieten und Triiodothyronin im Spiele zu sein.     

Potential for variability through multiple gene products of bacteriophage phiX174

The small single-stranded DNA phages phiX174 and S13 produce multiple products of certain phage genes, as observed by electrophoresis on SDS-polyacrylamide slab gels. Two A protein products, two A products and four G products are observed. The multiple gene products may arise from multiple sites for initiation or termination of translation, or by protein modification. Some of the variant products may provide a substitute for heterozygosity without a concomitant increase in the size of the genome.     

Filters for short non‐stationary sequences

This paper describes a methodology for implementing bidirectional frequency‐selective filters in cases where the data sequence is short and non‐stationary. A simple method is proposed for dealing with the start‐up problem. The method has a firm theoretical basis and it is computationally efficient. Copyright © 2001 John Wiley & Sons, Ltd.     

The genome of the green anole lizard and a comparative analysis with birds and mammals

The evolution of the amniotic egg was one of the great evolutionary innovations in the history of life, freeing vertebrates from an obligatory connection to water and thus permitting the conquest of terrestrial environments. Among amniotes, genome sequences are available for mammals and birds, but not for non-avian reptiles. Here we report the genome sequence of the North American green anole lizard, Anolis carolinensis. We find that A. carolinensis microchromosomes are highly syntenic with chicken microchromosomes, yet do not exhibit the high GC and low repeat content that are characteristic of avian microchromosomes. Also, A. carolinensis mobile elements are very young and diverse-more so than in any other sequenced amniote genome. The GC content of this lizard genome is also unusual in its homogeneity, unlike the regionally variable GC content found in mammals and birds. We describe and assign sequence to the previously unknown A. carolinensis X chromosome. Comparative gene analysis shows that amniote egg proteins have evolved significantly more rapidly than other proteins. An anole phylogeny resolves basal branches to illuminate the history of their repeated adaptive radiations.
