Background: We aimed to reveal if low dose X-rays would induce harmful or beneficial effect or dual response on biological cells and whether there are conditions the radiation can enhance gene transfer efficiency and promote cell growth but without ...

Relativistic Calculation of Anomalous Scattering Factors for X Rays
Anomalous scattering factors Δf′ and Δf″ have been calculated relativistically for Cr, Fe, Cu, Mo, and Ag Kα radiations for the atoms Li through Cf. An interpolation scheme for other wavelengths is included in a separate report. Relativistic calculations

Toll‐like receptors (TLRs) are important in the innate immune system. This study explores the zinc‐binding ability of the TLR2 TIR domain (TLR2TIR). We found that TLR2TIR binds zinc with nanomolar affinity through its cysteine residues. Two of them, C673 and C713, are vital for receptor activation, indicating that zinc may play a role in initiating ...

Extended range X-ray telescope [PDF]
An X-ray telescope system is described which is comprised of a tubular mount having a collecting region remote from the one axial end. A soft X-ray/XUV subsystem associated with the collecting region directs only relatively soft, near on-axis X-rays/XUV ...

Sources of X-rays from galaxies [PDF]
Galactic X-ray emission is a manifestation of various high-energy phenomena and processes. The brightest X-ray sources are typically accretion-powered objects: active galactic nuclei and low- or high-mass X-ray binaries.

Mallick et al. (2012, https://doi.org/10.1029/2012JD017555) discovered that subsequent‐stroke leaders in natural negative lightning could be more prolific producers of hard X‐rays and gamma rays than the first‐stroke leader in the same flash.

Reflection of X-Rays and X-Ray Fringes [PDF]
ACCOUNTS of the reflection of X-rays and of X-ray fringes contributed to NATURE by Messrs. Bragg, Moseley, Barkla, Hupke, Keene, and others induce me to send you some results that I have obtained recently in the same direction.
