Chemical phases analysis of Barium in Ores by X-ray Fluorescence Spectroscopy

PLOS One
Accurately determining the phase states of barium carbonate, barium silicate, and barium sulfate in ores. It’s crucial for advancing research on barium ore mineralization and improving beneficiation and smelting processes. This study aimed to investigate the integration of phase analysis and X-ray fluorescence spectrometry(XRF) to assess the phases of ...

DETERMINATION OF CHEMICAL COMPOSITION AND CRYSTAL PHASE OF FUME BY X-RAY FLUORESCENCE AND X-RAY DIFFRACTION ANALYSIS

INDUSTRIAL HEALTH, 1970
A combined use of X-ray fluorescent analysis and X-ray powder diffraction analysis is proposed for collecting precise and systematical information about the fundamental characteristics of fume from very small amount. This method, completely non-destruc-tive in most cases, can analyze directly the samples collected on filter paper and is able to ...

Analysis of Heme Using a Combination of Total Reflection X‐Ray Fluorescence Analysis and Solid‐Phase Extraction

X-Ray Spectrometry
ABSTRACT In this study, a method to analyze iron originating from heme using a combination of total reflection X‐ray fluorescence (TXRF) analysis and solid‐phase extraction is presented. In this method, heme in a sample solution was collected on a reverse‐phase solid‐phase extraction column filled with octadecyl ...

Analysis of nickel distribution by synchrotron radiation X-ray fluorescence in nickel-induced early- and late-phase allergic contact dermatitis in Hartley guinea pigs

Chinese Medical Journal, 2019
Nickel-induced allergic contact dermatitis (Ni-ACD) is a global health problem. More detailed knowledge on the skin uptake of haptens is required. This study aimed to investigate the penetration process and distribution of nickel in skin tissues with late phase and early phase of Ni-ACD to understand the mechanisms of metal allergy.Forty Hartley guinea

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

Molecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Effect of terahertz irradiation on DNA damage repair in living cells

FEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.
