It is necessary to deplete the endogenous primordial germ cells (PGCs) from recipient embryos when germline chimaeric chickens are produced by the transfer of PGCs. In this study, effects of soft X-ray irradiation on the restriction of PGC proliferation

We present a miniaturized and wide field-of-view X-ray and Gamma-ray imager consisting of a segmented 2D optics-collimator coupled to the high-sensitivity semiconductor pixel detector Timepix equipped with a high-Z sensor (CdTe 2000 μm thick).

INTEGRAL observations of the blazar 3C454.3 in outburst [PDF]
In Spring 2005, the blazar 3C454.3 underwent a dramatic outburst at all wavelengths from mm to X-rays. This prompted INTEGRAL observations, accomplished in 15-18 May 2005. The source was detected by the INTEGRAL instruments from 3 to 200 keV in a bright state (~5 x 10E-10 cgs), at least a factor of 2-3 higher than previously observed.

A Quantum Theory of the Scattering of X-rays by Light Elements
A quantum theory of the scattering of X-rays and $\ensuremath{\gamma}$-rays by light elements.---The hypothesis is suggested that when an X-ray quantum is scattered it spends all of its energy and momentum upon some particular electron.

Mapping Hsp104 interactions using cross‐linking mass spectrometry
This study examines how cross‐linking mass spectrometry can be utilized to analyze ATP‐induced conformational changes in Hsp104 and its interactions with substrates. We developed an analytical pipeline to distinguish between intra‐ and inter‐subunit contacts within the hexameric homo‐oligomer and discovered contacts between Hsp104 and a selected ...
