Investigation of Structural and Luminescent Properties of Sol-Gel-Derived Cr‑Substituted Mg3Al1−xCrx Layered Double Hydroxides

open access: yesMolecules, 2021
In the present work, Cr-substituted Mg3Al1−xCrx layered double hydroxides (LDHs) were synthesised through the phase conversion of sol-gel-derived mixed-metal oxides in an aqueous medium.

Process for the production of star-tracking reticles [PDF]

open access: yes, 1974
Reticles designed with quartz bases are masked with desired pattern and then are coated with highly adherent layers of chromium, chromium silver alloy, silver, copper, and black chromium (mixture of chromium and chromium oxides).

On-line preconcentration using dual mini-columns for the speciation of chromium(III) and chromium(VI) and its application to water samples as studied by inductively coupled plasma-atomic emission spectrometry [PDF]

open access: yes, 2005
On-line preconcentration system for the selective, sensitive and simultaneous determination of chromium species was investigated. Dual minicolumns containing chelating resin were utilized for the speciation and preconcentration of Cr(III) and Cr(VI) in ...

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

open access: yesMolecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

Chromium Pollution and Mitigation in a Sunflower Farmland System

open access: yesAgronomy
Chromium is a major heavy metal pollutant that affects the health of both plants and animals. In this study, sunflower seedlings were treated with K2Cr7O4 containing 50, 100, and 250 mg of pure chromium per kilogram of soil.

Chromium (III) and chromium (VI) as important players in the induction of genotoxicity - current view.

open access: yesAnnals of Agricultural and Environmental Medicine, 2020
INTRODUCTION Genotoxicity of chemical compounds is primarily associated with the interaction with DNA, formation of mutations, damage to chromosomes and initiating carcinogenesis processes.

Reduced vascular leakage correlates with breast carcinoma T regulatory cell infiltration but not with metastatic propensity

open access: yesMolecular Oncology, EarlyView.
A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

Tetrakis(μ-acetato-κ2O:O′)bis[(tetrahydrofuran-κO)chromium(II)]

open access: yesIUCrData, 2023
The title compound, [Cr2(C2H3O2)4(C4H8O)2] or [Cr2(OAc)4(THF)2] (OAc is acetate, THF is tetrahydrofuran), was obtained by recrystallization of anhydrous chromium(II) acetate [Cr2(OAc)4] from hot tetrahydrofuran.

Adsorptive removal of chromium(VI) from aqueous solution unto groundnut shell

open access: yesApplied Water Science, 2019
Chromium present in high levels in water poses a serious problem in many places around the world, sometimes in relation to natural sources and in other cases to anthropogenic ones.
