Modulation of Fe-Fe distance and spin in diiron complexes using tetradentate ligands with different flanking donors.

Here we report the synthesis and characterization of diiron complexes containing triaryl N and NS ligands derived from -phenylenediamine. The complexes display significant differences in Fe-Fe distances and magnetic properties that depend on the identity of the flanking NMe and SMe donor groups.

The Effects of Lithium Chloride Exposure on the Reproduction of .

( are model organisms that share similar anatomical structures to humans. By exploring the effects of lithium chloride (LiCl) on we can collect crucial data regarding the compound's impact on patients taking psychiatric medications containing LiCl. Here we performed an egg retention assay on nematode populations to explore how LiCl can influence reproduction.

Liver Biopsy: To Do or Not to Do - A Single-Center Study.

Introduction: A variety of liver disorders are associated with characteristic histopathological findings that help in their diagnosis and treatment. However, percutaneous liver biopsy (PLB) is prone to limitations and complications. We evaluated all PLBs done in our hospital in a 13-year period, aiming to assess PLB's utility and complications.

Single Nucleotide Polymorphisms of Toll-like Receptor 4 in Hepatocellular Carcinoma-A Single-Center Study.

Hepatocellular carcinoma (HCC) is the most common primary liver tumor leading to significant morbidity and mortality; its exact genetic background is largely unrecognized. Toll-like receptor-4 (TLR4) reacts with lipopolysaccharides, molecules found in the outer membrane of Gram-negative bacteria. In damaged liver, TLR4 expression is upregulated, leading to hepatic inflammation and injury.

Redox chemistry and H-atom abstraction reactivity of a terminal zirconium(iv) oxo compound mediated by an appended cobalt(i) center.

The reactivity of the terminal zirconium(iv) oxo complex, O[triple bond, length as m-dash]Zr(MesNPPr)CoCN Bu (), is explored, revealing unique redox activity imparted by the pendent redox active cobalt(i) center. Oxo complex can be chemically reduced using Na/Hg or PhC to afford the Zr/Co complexes [(μ-Na)OZr(MesNPPr)CoCN Bu] () and PhCOZr(MesNPPr)CoCN Bu (), respectively. Based on the cyclic voltammogram of , Ph˙ should not be sufficiently reducing to achieve the chemical reduction of , but sufficient driving force for the reaction is provided by the nucleophilicity of the terminal oxo fragment and its affinity to bind PhC.
