Adaptation and major chromosomal changes in populations of Saccharomyces cerevisiae
(Springer-Verlag, 1992-07)
Thirteen independent populations of Saccharomyces cerevisiae (nine haploid and four diploid) were maintained in continuous culture for up to approximately 1000 generations, with growth limited by the concentration of organic ...
Quantitative energy-filtered electron microscopy of biological molecules in ice
(Elsevier, 1992-10)
The theoretical and experimental bases for quantitative electron microscopy of frozen-hydrated specimens are described, with special considerations of energy filtration to improve the images. The elastic and inelastic ...
Cloning and characterization of the cDNA encoding human adenylosuccinate synthetase
(Elsevier, 1992-05-25)
Adenylosuccinate synthetase (AS) catalyzes the first committed step in the conversion of IMP to AMP. A cDNA was isolated from a human liver library which encodes a protein of 455 amino acids (Mr of 49.925). Alignments of ...
Control of steroid receptor function and cytoplasmic-nuclear transport by heat shock proteins
(Wiley Subscription Services, Inc., A Wiley Company, 1992-12)
As targeted proteins that move within the cell, the steroid receptors have become very useful probes for understanding the linked phenomena of protein folding and transport. From the study of steroid receptor-associated ...
Digestion of uncrushed leaf tissues by leaf-snipping larval Lepidoptera
(Springer-Verlag, 1992-02)
Cynodon dactylon (Poaceae) leaf pieces recovered from the frass of final-instar Paratrytone melane larvae (Lepidoptera: Hesperiidae) were composed of 14–22 percent crushed cells and 78–86 percent uncrushed cells, yet ...
Stimulation of myenteric plexus neurite outgrowth by insulin and insulin-like growth factors I and II
(Elsevier, 1992)
A defined culture medium containing insulin, insulin-like growth factor I (IGF-I) or insulin-like growth II (IGF-II) supported morphological development of myenteric plexus neurons derived from neonatal guinea pigs. Insulin ...
The genes for the inter-α-inhibitor family share a homologous organization in human and mouse
(Springer-Verlag, 1992-12)
Inter-α-inhibitor ( IαI ) and related molecules in human are comprised of three evolutionarily related, heavy (H) chains and one light (L) chain, also termed bikunin. The latter originates from a precursor molecule that ...
