Auxetic Behavior in JUC‐530: The Effect of Interstitial Molecules on Framework Deformation

open access: yesphysica status solidi (b), Volume 263, Issue 5, May 2026.
Auxetic behavior in the JUC‐530 covalent organic framework is predicted by molecular modeling to arise from a cooperative tetrahedral‐flattening mechanism within the framework topology. Guest molecule loading (N2, CH4, benzene) is shown to suppress the negative Poisson's ratio response.

"Artifactual" arsenate DNA

open access: yes, 2012
The recent claim by Wolfe-Simon et al. that the Halomonas bacterial strain GFAJ-1 when grown in arsenate-containing medium with limiting phosphate is able to substitute phosphate with arsenate in biomolecules including nucleic acids and in particular DNA(

Investigating the Therapeutic Potential of Tamarix aphylla Leaf Extract Against Toxicity Caused by Graphene Nanosheets in Cirrhinus mrigala

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Tamarix aphylla leaf extract significantly alleviated graphene nanosheet–induced toxicity in Cirrhinus mrigala, reducing oxidative tissue damage and restoring organ integrity. Rich in antioxidant compounds, the extract offers a promising natural strategy for mitigating the biological impacts of graphene‐related pollutants.

Effects of arsenate on the growth and microcystin production of Microcystis aeruginosa isolated from Taiwan as influenced by extracellular phosphate

open access: yes, 2009
Arsenic pollution and eutrophication are both prominent issues in the aquaculture ponds of Taiwan. It is important to study the effects of arsenic on algal growth and toxin production in order to assess the ecological risk of arsenic pollution, or at ...

Potential Impacts of Tailings and Tailings Cover Fertilization on Arsenic Mobility in Surface and Ground Waters

open access: yes, 2008
A number of mining sites worldwide, particularly gold mines, have tailings management facilities (TMFs) that contain high levels of arsenic. Current closed mine site regulatory agencies tend to prefer revegetation of TMFs as part of the mandated ...

Phytochelatins are involved in differential arsenate tolerance in Holcus lanatus [PDF]

open access: yes, 2001
Arsenate tolerance is conferred by suppression of the high-affinity phosphate/arsenate uptake system, which greatly reduces arsenate influx in a number of higher plant species. Despite this suppressed uptake, arsenate-tolerant plants can still accumulate

Synergistic interaction of glyceraldehydes-3-phosphate dehydrogenase and ArsJ, a novel organoarsenical efflux permease, confers arsenate resistance

open access: yesMolecular Microbiology, 2016
Microbial biotransformations are major contributors to the arsenic biogeocycle. In parallel with transformations of inorganic arsenic, organoarsenicals pathways have recently been recognized as important components of global cycling of arsenic.

RESPONSE OF MICROCYSTIS AERUGINOSA TO ARSENATE UNDER DIFFERENT PHOSPHATE REGIMES

open access: yes, 2009
Arsenic is ubiquitous in the environment and potentially toxic to humans. Arsenate, thermodynamically the dominant specie of arsenic in marine and estuarine surface waters, was shown to be taken up by the phosphate transport systems of phytoplankton and ...

Possible Roles of Plant Sulfurtransferases in Detoxification of Cyanide, Reactive Oxygen Species, Selected Heavy Metals and Arsenate

open access: yesMolecules, 2015
Plants and animals have evolved various potential mechanisms to surmount the adverse effects of heavy metal toxicity. Plants possess low molecular weight compounds containing sulfhydryl groups (-SH) that actively react with toxic metals.
