New insights into the acid mediated disproportionation of pentavalent uranyl.

Pentavalent uranyl stabilized by a dianionic bulky tetradentate ligand.

A pentavalent uranyl complex supported by a bulky dianionic tetradentate (ONNO)-type salan ligand has been prepared by direct synthesis from the iodide precursor {[UO(2)Py(5)][KI(2)Py(2)]}(n), and displays high stability towards disproportionation and ligand dissociation but reactivity towards oxidizing substrates.

New Insights into the Effect of Diabetes and Obesity in Alzheimer’s Disease

Abstract Alzheimer’s disease (AD) is the most common cause of dementia in elderly people. The prevalence of Alzheimer diseases is increasing in the world due to population aging. Metabolic disease such as diabetes and obesity play important role in Alzheimer disease. Hyperglycemia can play important role in brain damage. It causes cognitive impairments, functional and structural alterations in...

Easy access to stable pentavalent uranyl complexes.

Reaction of UO2I2(THF)3 with 1 molar equivalent of KC5R5 (R = H, Me) in pyridine led to the uranyl(V) compound {[UO2(Py)5][KI2(Py)2]}(infinity), which is an infinite 1D polymer in its crystalline form; the UO2X(THF)n (X = I, OSO2CF3) complexes were obtained by reduction of their U(VI) parents with TlC5H5 or KC5R5 in THF.

Possible Causes of Ileal Injury in Two Models of Microbial Sepsis and Protective Effect of Phytic Acid

Background: Sepsis related-multiple organ dysfunction is associated with ileum injury. We aimed to determine the causes of ileal injury in two models of microbial sepsis resulted from infection with Aeromonas hydrophila or its endotoxin. We also evaluated the protective effect of phytic acid. Methods: Thin sections of ileum from 60 Swiss male mice in control, bacteria-infected or lipopolysaccha...
