CYP3A4*1G has an impact on the analgesic effect of fentanyl in Chinese Han subjects. Further validation of our results in a well-powered study would be helpful.

Based on a facile vapor-phase transport method without any catalyst and template, one-dimensional single-crystalline bismuth oxide (Bi2O3) micro/nanoribbons were fabricated on silicon substrates in large quantities and morphology-controlled fabrication of Bi2O3 was achieved from a single precursor. The widths of Bi2O3 ribbons varied from 0.2 to 20 microm depending on the deposition temperatures. The thickness was in the range of 0.1-2 microm and the length reached several hundred micrometers and even millimeter range. The detailed composition and structural analysis confirmed the single-crystalline nature of alpha-Bi2O3 micro/nanoribbons with monoclinic structure. The photoluminescence spectrum of a single Bi2O3 ribbon showed a broadband emission from 450 to 750 nm in the visible region, consisting two peaks located at 589 and 697 nm which were primarily originated from the impurity ions and crystal defects. A self-catalyzed vapor-solid model was proposed to account for the growth mechanism of Bi2O3 ribbons with different morphologies.

Presented herein is an investigation into the stretching and fracture behavior of single-walled carbon nanotubes (SWCNT) subjected to axial tensile load at various temperatures. This study is carried out using molecular dynamics (MD) simulation at temperatures ranging from 200 K to 2200 K. The authors find that single-walled carbon nanotubes exhibit obvious temperature and chirality dependent properties. The values of tensile strain and tensile strength of zigzag (12, 0) and armchair (7, 7) SWCNTs with similar radii decrease with increase in temperature, but decline slightly on different slopes. The stress-strain curves of zigzag and armchair SWCNTs vary significantly when the temperature is more than 1200 K. Our studies suggest temperature and chirality play an important role in determining the tensile strength and tensile strain of SWCNT.
