Quantum Impurity Rotator in a Matrix of Quantum Rotors: Electron Paramagnetic Resonance Dynamics of CH in Solid CD Matrix.

The rotational dynamics and the geometry of a light and flexible impurity molecule like methyl, matrix isolated in van der Waals solid, are supposed to be sensitive to the host molecule dynamics and order alterations of the matrix. In addition, the location of the impurity and its interaction with the matrix molecules is of prime importance. Large energy gaps between rotation levels of quantum rotators allow precise investigation of temperature-assisted quantum tunneling effects.

Uninephrectomized High-Fat-Fed Nicotinamide-Streptozotocin-Induced Diabetic Rats: A Model for the Investigation of Diabetic Nephropathy in Type 2 Diabetes.

Type 2 diabetes (DM2) could be reproduced in rats with alimentary obesity by using low doses of streptozotocin (LD-STZ) as well as STZ in high doses with preliminary nicotinamide (NA) administration. However, STZ could induce tubulotoxicity. .

Methyl Radical in Clathrate Silica Voids. The Peculiar Physisorption Features of the Guest-Host Molecular Dynamics Interaction.

EPR line shape simulations of CH3/SiO2 clathrates and comparison to CH3/N2O and CH3/SiO2 experiments reveal the motional conditions of the CH3 radical up to the unusual regime of its stability, the high-temperature diffusional regime, at 300 K. In the low-temperature region, the CH3 in clathrates is found to rotate around the in-plane axes even at as low temperatures as 3.8 K.

Effects of Inhibitors of Necroptosis and Autophagy on Morphofunctional Characteristics of the Myocardium during Static Cold Storage of Donor Rat Heart.

Cardioprotective effects of necrostatin-1 (necroptosis inhibitor) and 3-methyladenine (autophagy inhibitor) were studied on the model of long-term cold preservation of rat heart. Addition of necrostatin-1 (490 nmol/liter) or 3-methyladenine (4.5 mmol/liter) to custodiol preserving solution reduced myocardial infarction size and improved left-ventricular function during reperfusion after 8-h preservation at 4°C.

[CARDIOPROTFETIVE EFECTS OF NECROSTATIN-7 IN THE RAT MODEL OF PERMANENT CORONARY OCCLUSION].

The cardioprotective effects of necroptosis inhibitor necrostatin-7 were studied in the rat model of permanent coronary occlusion. It was found that intraperitoneal injection of necrostatin-7 at a dose of 14.5 mg/kg 60 minutes prior to permanent left coronary artery occlusion reduced the amount of scar tissue and scar length in the left ventricle on the 21st day after surgery.
