The structure of the title compound, [MnCl(2)(C(5)H(10)O(2))(2)], was solved from low-temperature data collected at 100 (2) K. The asymmetric unit contains one half-mol-ecule with the Mn(II) ion located on a twofold axis. A distorted octa-hedral environment around the Mn atom is formed by two ether and two hydroxyl O atoms of two 2-(hydroxy-methyl)tetra-hydro-furan ligands, and by two chloride ions. The chelating tetra-hydro-furan ligands, which form five-membered rings, are cis oriented. The crystal structure is stabilized by hydrogen bonding between the coordinated OH groups and the chloride ions.

The persistence and ecological impact of per- and poly-fluoroalkyl substances (PFAS) in water sources necessitate effective and energy-efficient treatment solutions. This study introduces a novel approach using cerium dioxide (CeO) electrodes enhanced with oxygen vacancy (O) to catalyze the defluorination of PFAS. By leveraging the unique affinity between cerium and fluorine-containing species, our approach enables adsorptive preconcentration and catalytic degradation at low oxidation potentials (1.

Chloride (Cl) ions cause major damage to crops in saline soils. Understanding the key factors that influence Cl uptake and translocation will aid the breeding of more salt-tolerant crops. Here, using genome-wide association study and transcriptomic analysis, we identified a NITRATE TRANSPORTER 1 (NRT1)/PEPTIDE TRANSPORTER family (NPF) protein, GmNPF7.

Background: Manganese (Mn) is an essential metal that serves as a cofactor for metalloenzymes important in moderating the glutamate/glutamine cycle and other oxidative stress pathways. Typically, Mn is acquired through the diet, however, Mn overexposure can arise through drinking inadequately treated well water or inhalation of Mn-containing industrial byproducts. Mn toxicity disrupts dopaminergic neurotransmission resulting in a Parkinsonian disorder referred to as manganism.

Background: The brain is a potential target for aluminium toxicity as it induces oxidative stress, strategies, rich in polyphenolic compound, containing flavonoid and possessing antioxidant property, found in natural plant products, to attenuate aluminium-induced impairments could provide a potential therapeutic intervention and protection for aluminium neurotoxicity.
Method: Forty adult rats weighing between 160 - 165g was used. The rats were divided into four groups (n = 10).

Monovalent salts are generally believed to stabilize DNA duplex by weakening inter-strand electrostatic repulsion. Unexpectedly, our force-induced hairpin unzipping experiments and thermal melting experiments show that LiCl, NaCl, KCl, RbCl, and CsCl at concentrations beyond ~1 M destabilize DNA, RNA, and RNA-DNA duplexes. The two types of experiments yield different changes in free energy during melting, while the results that high concentration monovalent salts destabilize duplexes are common.
