Rapid Publications Sequence of a cDNA Encoding Syrian Hamster Preproinsulin GRAEME I. BELL AND RAY SANCHEZ-PESCADOR

چکیده
A complementary DNA (cDNA) library was prepared from messenger RNA (mRNA) isolated from Syrian hamster islets. Bacterial colonies containing hamster preproinsulin cDNA were identified by cross-hybridization with the human preproinsulin gene. The sequences of two of these established the complete sequence of Syrian hamster preproinsulin mRNA and predicted the sequence of the protein. Hamster preproinsulin is 110 amino acids and possesses 90.0% and 82.7% identity with the corresponding proteins of rats (either I or II) and human beings, respectively. Analysis of the hybridization of hamster preproinsulin cDNA to restriction endonuclease digests of hamster DNA suggests that there is only a single preproinsulin gene in this rodent, in contrast to rats and mice, which possess two nonallelic genes.

Paleoenvironmental Reconstruction of Miocene Surma Succession in the Well Rashidpur # 04 of Bengal Basin Using Log Facies Interpretation
Detailed log facies studies of Miocene succession in the well Rashidpur-04, Rashidpur structure, Surma Basin were carried out by integrating wireline log and limited core sample data in order to reconstruct the paleoenvironments of deposition. Based on the analysis of the log motifs, grain size, sand/shale ratio and major change in gamma ray log motifs, two major depositional sequences were ide...
متن کاملEffects of thermal expansion of crystal-lattice on x-ray imaging crystal spectrometers
X-ray imaging crystal spectrometers with high spectral and spatial resolution are currently being used on magnetically confined fusion schemes to infer the time history of profiles of the ion and electron temperatures as well as plasma flow velocities. Recent studies indicate that the crystal temperature must be kept constant within a fraction of a degree to avoid changes of the interplanar 2d-...
متن کاملOn the chemical state of Co oxide electrocatalysts during alkaline water splitting.
Resonant inelastic X-ray scattering and high-resolution X-ray absorption spectroscopy were used to identify the chemical state of a Co electrocatalyst in situ during the oxygen evolution reaction. After anodic electrodeposition onto Au(111) from a Co(2+)-containing electrolyte, the chemical environment of Co can be identified to be almost identical to CoOOH. With increasing potentials, a subtle...
متن کاملSynchronous x-ray and radio mode switches: a rapid global transformation of the pulsar magnetosphere.
Pulsars emit from low-frequency radio waves up to high-energy gamma-rays, generated anywhere from the stellar surface out to the edge of the magnetosphere. Detecting correlated mode changes across the electromagnetic spectrum is therefore key to understanding the physical relationship among the emission sites. Through simultaneous observations, we detected synchronous switching in the radio and...
متن کاملRealisation of magnetically and atomically abrupt half-metal/semiconductor interface: Co2FeSi0.5Al0.5/Ge(111)
Halfmetal-semiconductor interfaces are crucial for hybrid spintronic devices. Atomically sharp interfaces with high spin polarisation are required for efficient spin injection. In this work we show that thin film of half-metallic full Heusler alloy Co2FeSi0.5Al0.5 with uniform thickness and B2 ordering can form structurally abrupt interface with Ge(111). Atomic resolution energy dispersive X-ra...
