Deciphering the catalytic and pharmacological mechanisms of Coptis chinensis herbzymes to renovate intestinal microenvironment for colitis alleviation

BMEMat, EarlyView.
The synthesized CCzymes possess both antioxidant enzyme activity and pharmacological properties inherent to Coptis chinensis. By their antioxidant enzyme activity, CCzymes can attenuate oxidative stress within the inflammatory region of ulcerative colitis (UC), while their pharmacological activity acts on macrophage polarization and the intestinal ...

X-ray bursts

Tours symposium on nuclear physics III, 1998
The observations and progress in the theoretical understanding of X-ray burst sources are reviewed. Of about 150 known low mass X-ray binary systems, X-ray bursts have been observed from about 50 sources. X-ray bursts exhibit a wide variety of profiles; rise times vary from less than a second to about 10 s and decay times are in the range of 10 s to ...

X-Ray Bursts from Soft X-Ray Transients

Publications of the Astronomical Society of Japan, 1986
Abstract The thermal evolution of a neutron star in a soft X-ray transient is computed from an off-accretion phase through the first shell flash after an onset of the accretion. The structure and the evolution of the whole neutron star are solved by taking account of general relativity properly.

X-Ray Bursts

1991
We summarize the observed features of X-ray bursts and the key elements of the thermonuclear flash model of this phenomenon. We then elucidate the full range of possible burst behavior using a global analysis of the stability of nuclear burning on accreting neutron stars.

X-ray bursts puzzle theorists

Physics World, 1996
Most of the brightest sources in the X-ray sky are binary systems in which a small, dense neutron star and a companion star orbit around each other. The neutron star, which has a strong gravitational field, accretes matter from its companion. As this matter falls into the neutron star, it is heated to temperatures high enough to radiate predominantly ...

On maximum luminosities of X-ray bursts

Space Science Reviews, 1985
In this paper we address problems associated with the observation of super-Eddington luminosities in X-ray burst sources and discuss some possible solutions.
