Revealing the Drag Instability in One-fluid Nonideal Magnetohydrodynamic Simulations of a 1D Isothermal C-shock
Abstract
C-type shocks are believed to be ubiquitous in turbulent molecular clouds thanks to ambipolar diffusion. We investigate whether the drag instability in 1D isothermal...
Distribution of horseradish peroxidase (HRP)- anti-HRP immune complexes in mouse spleen with special reference to follicular dendritic cells
The distribution of immune complexes has been studied in mouse spleen stimulated to contain many germinal centers (GC?s). Horseradish peroxidase (HRP)-anti-HRP complexes were used as an appropriately precise and sensitive model....

The different catalytic roles of the metal- binding ligands in human 4-hydroxyphenylpyruvate dioxygenase
Chih-Wei Huang, Hsiu-Chen Liu, Chia-Pei Shen, Yi-Tong Chen, Sung-Jai Lee, Matthew D. Lloyd, Hwei-Jen Lee
May 01, 2016
4‐Hydroxylphenylpyruvatedioxygenase (HPPD) is a non‐haem iron(II)‐dependent oxygenase that catalyzes the conversion of 4‐hydroxylphenylpyruvate (HPP) to homogentisate (HG). In the active site, a strictly conserved 2‐His‐1‐Glu...
The evidence for Shiatsu
BACKGROUND: Shiatsu, similar to acupressure, uses finger pressure, manipulations and stretches, along Traditional Chinese Medicine meridians. Shiatsu is popular in Europe, but lacks reviews on its...
DNMTs Play an Important Role in Maintaining the Pluripotency of Leukemia Inhibitory Factor-Dependent Embryonic Stem Cells.
