Photoinduced Oxidation of Arsenite to Arsenate on Ferrihydrite

, 2016
The photochemistry of an aqueous suspension of the iron oxyhydroxide, ferrihydrite, in the presence of arsenite has been investigated using attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), X-ray absorption near edge ...

Arsenite Induced Disruption of Mitosis

, 2018
Arsenite is a known carcinogen that causes skin, bladder, and liver cancer. However, the mechanism of carcinogenesis is unknown. Arsenite (AsO2 - ) delays entry into mitosis by activation of the G2 checkpoint.

Using PEDOT Film Modified Electrode to Monitor Iodide and Its Enhancement of Arsenite Sensing

International Journal of Electrochemical Science, 2011
Iodide was investigated using poly(3,4-ethylenedioxythiophene)/glassy carbon electrode (PEDOT/GCE) as an monitoring tool. When this electrode was scanned to the positive potential (+0.7 V) in the presence of 6x10-3 M, the redox couple was gradually ...

RNA Promotes Synapsin Condensates That Organize Synaptic Vesicles in Live Neurons and Enable Localized Translation in Reconstituted System

Advanced Science, Volume 13, Issue 60, 28 October 2026.
Condensates at synapses organize synaptic vesicles (SVs) and are crucial for efficient neurotransmitter release, yet how RNA contributes to this mesoscale architecture remains poorly understood. Here we uncover that RNA modulates synapsin–driven condensates.

Endoplasmic Reticulum Stress Is Involved in Arsenite-Induced Oxidative Injury in Rat Brain

, 2009
The mechanism underlying sodium arsenite (arsenite)-induced neurotoxicity was investigated in rat brain. Arsenite was locally infused in the substantia nigra (SN) of anesthetized rat.

Protective effect of silymarin on viability, motility and mitochondrial membrane potential of ram sperm treated with sodium arsenite

Iranian Journal of Reproductive Medicine, 2016
Background: Sodium arsenite can impair male reproductive function by inducing oxidative stress. Silymarin is known as a potent antioxidant. Objective: This study was performed to investigate if silymarin can prevent the adverse effect of sodium arsenite

Assessing the Mutational Consequences of Chronic Arsenic Exposure Using Patient‐Derived Tumor Samples and In Vitro Systems

Environmental and Molecular Mutagenesis, Volume 67, Issue 8-9, October-November 2026.
ABSTRACT Inorganic arsenic, a naturally occurring metalloid found in groundwater, is a well‐established human carcinogen. Epidemiological studies from highly contaminated regions link chronic arsenic exposure to increased risks of skin, lung, bladder, and kidney cancer.
