Apolipoprotein B amino acid 3611 substitution from arginine to glutamine creates the Ag (h/i) epitope: the polymorphism is not associated with differences in serum cholesterol and apolipoprotein B levels
A G-to A-DNA sequence change in exon 26 of the human apolipoprotein B (apo B) gene leads to a glutamine substitution for arginine at codon 3611 of the mature apolipoprotein B100 and causes a loss of an MspI site....

Measurements of excitation spectra and level lifetimes for highly charged neon ions
Beam foil experiments were carried out for 47 MeV Ne ions passing through C (39 μg/cm2) and A1 (3.4mg/cm2) foils. Highly charged H-, He-., Li-, and Be-like ions were obtained after the foils. The excitation spect...

Water-rock interaction in Tarim Basin: Constraints from oilfield water geochemistry
Oilfield waters from Cenozoic and Mesozoic terrestrial and Paleozoic marine environments in the Tarim Basin show no obvious difference in water chemistry except Br and isotopic compositions. The Paleozoic mari...

Time and energy operators in quantum mechanics
Starting from a time operator, the form of the so-called energy operator that is conjugate to the time operator is derived in time representation by analyzing the properties of time translation. This analysis ...

(EC +β+) decay study of 128Ce
The (EC+β+) decay of 128Ce was reinvestigated in the 116Sn (16O, 4n) reaction by using a helium-jet tape transport system. The close half-lives of 128Ce and 129Ce made it difficult to separate the decay γ rays o...
