Human somatotropin competed for 125I-human somatotropin binding to hepatocytes from female or male rats. Bovine somatotropin and prolactin each inhibited part, but not all, of the uptake of 125I-human somatotropin. The binding of 125I-prolactin was inhibited by human somatotropin and prolactin, but not by bovine somatotropin. Bovine somatotropin and human somatotropin, but not prolactin, compet...

Reconstructions of the GaN(000 ) surface are studied for the first time. Using scanning tunneling microscopy and reflection high-energy electron diffraction, four primary structures are observed: 1×1, 3×3, 6×6, and c(6×12). On the basis of first-principles calculations, the 1×1 structure is shown to consist of a Ga monolayer bonded to a N-terminated GaN bilayer. From a combination of experiment...

We prove that any simpli cation order over arbitrary terms is an extension of an order by weight, by considering a related monadic term algebra called the spine. We show that any total ground-stable simpli cation order on the spine lifts to an order on the full term algebra. Conversely, under certain restrictions, a simpli cation ordering on the term algebra de nes a weight function on the spin...

The coming of giga-bit networks makes possible the realization of a single nationwide virtual computer comprised of a variety of geographically distributed highpe6ormance machines and workstations. To realize the potential that the physical infrastructure provides, software must be developed that is easy to use, supports large degrees of parallelism in applications code, and manages the complex...

Surface reconstructions and adatom kinetics of silicon on GaN(0001) and (000 ) surfaces are studied by scanning tunneling microscopy, electron diffraction and first-principles calculations. In the low silicon coverage regime a 2×2 structure is observed, and is interpreted in terms of a model consisting of a Ga adatom on a monolayer of 3Ga + 1 Si and a SiGa atom in the third layer. For high sili...

By the time you read this editorial, I will have returned from the American Dental Hygienists' Association (ADHA) Annual Session in Albuquerque, NM. I have never been to Albuquerque, but when I think of the city, I think of hot air balloons. It amazes me to think of the heights the balloons can reach and the view the passengers can see when they look down and across the landscape at several hun...

This study aimed to reconstruct a three-dimensional map of axonal mitochondria using Fiji and Neurolucida software, and to observe directly the morphology and distribution of mitochondria in axons of motor neurons in dorsal longitudinal flight muscles of drosophila aged 5 days and 20 days, using electron microscopy. Results indicated that there was no difference in the total area and volume of ...

The major fraction of seed storage proteins of Agrostemma githago (corn-cockle), a non-leguminous dicot, occurs as material with S20,w values of approximately 11S and approximately 2S, and a minor fraction as oligomers with S20,w values of approximately 6.5S. The 11S proteins are of the legumin type and consist of disulphide-linked alpha- and beta-subunits of Mr approximately 39 000 and approxi...
