Thionitrosyl Complexes of Rhenium and Technetium with PPh₃ and Chelating Ligands—Synthesis and Reactivity

Inorganics
In contrast to corresponding nitrosyl compounds, thionitrosyl complexes of rhenium and technetium are rare. Synthetic access to the thionitrosyl core is possible by two main approaches: (i) the treatment of corresponding nitrido complexes with S2Cl2 and (

GAMMAGRAFÍA DE PERFUSIÓN MIOCÁRDICA EN MUJERES POSMENOPÁUSICAS CON ANGINA Y CORONARIAS EPICÁRDICAS ANGIOGRÁFICAMENTE NORMALES / Myocardial perfusion scintigraphy in postmenopausal women with angina and angiographically normal epicardial coronary [PDF]

CorSalud, 2011
Introduction and Objectives: Microvascular angina is common in postmenopausal women. Myocardial ischemia was induced by stress testing, and reports have been published about the relationship between endothelial dysfunction and myocardial perfusion.

Technetium and the third dredge up in AGB stars. I. Field stars

, 2003
We searched for Tc in a sample of long period variables selected by stellar luminosity derived from Hipparcos parallaxes. Tc, as an unstable s-process element, is a good indicator for the evolutionary status of stars on the asymptotic giant branch (AGB).

Enhanced discovery of bacterial laccase‐like multicopper oxidase through computer simulation and metagenomic analysis of industrial wastewater

FEBS Open Bio, EarlyView.
We obtained potential bacterial laccase‐like multicopper oxidase (LMCO) sequences through metagenomic sequencing. All sequences exhibited significant differences from known LMCOs in databases. To select the most promising candidates, we performed structure prediction and molecular docking using alphafold2, metal3d and rosetta.

Co‐overexpression of the caloric restriction‐induced mitochondrial factors PGC‐1α and MIPEP upregulates Phospho1 expression in adipocytes

FEBS Open Bio, EarlyView.
Caloric restriction that extends lifespan induces the expression of PGC‐1α and MIPEP in white adipose tissue. In this study, co‐overexpression of Pgc‐1α and Mipep upregulated the gene expression of PHOSPHO1. These findings provide new insights into mitochondria‐related mechanisms underlying the effects of caloric restriction in adipocytes.

The effect of an iodine restricted including no sea foods diet, on technetium-99m thyroid scintigraphy: A neglected issue in nuclear medicine practice [PDF]

, 2012
Although it is recommended to patients to avoid sea food and iodine-containing medications prior to iodine-131 ( 131I) scanning, the efficacy of this diet as for technetium-99m pertechnetate ( 99mTc-P) thyroid scintigraphy is not well addressed in the ...
