Evaluation of Peripheral Neuropathy in Rat Models of Metabolic Syndrome and Diabetes Mellitus.

The dynamics of nephropathy development in rats with type 2 diabetes mellitus, caused by a high-fat diet and the streptozotocin administration (25 mg/kg), and metabolic syndrome, caused by addition of 20% fructose solution to the diet, was evaluated during the experiment. Models with moderate severity of metabolic changes without significant changes in body weight were obtained after 24 weeks. To study neuropathy severity, the method of electroneuromyography was used; the velocities of motor and sensory excitation propagation along the caudal nerve fibers were measured.

Dihydroquercetin-Loaded Liposomes Change Fibrous Tissue Distribution in the Bleomycin-Induced Fibrosis Model.

The effects of the antioxidant dihydroquercetin (DHQ) were studied in a model of pulmonary fibrosis. DHQ penetration into the lesion was facilitated by encapsulation into liposomes. Pulmonary fibrosis was modeled in rats by intratracheal injection of bleomycin.

Comparison of Metabolic Changes after 6 Months of High-Carbohydrate Diet or High-Fat Diet with Low Dose Streptozotocin Injection in Rats.

We compared 2 models of metabolic syndrome in rats: high-fat diet (58% calories) with single streptozotocin injection at a dose of 25 mg/kg and replacement of water with 20% fructose solution. The model with fructose solution did not cause the main signs of metabolic syndrome over 24 weeks: concentrations of glucose, triglycerides, cholesterol, weight, and BP did not significantly differ from the control group (standard diet). At the same time, single streptozotocin administration was followed by the development of persistent hyperglycemia, hypertriglyceridemia, hypercholesterolemia, and signs of visceral obesity.

Evaluation of the efficacy of permethrin- and cypermethrin-based textile against taiga tick, Ixodes persulcatus.

A comparison of the efficacy of permethrin- and cypermethrin-based textile against taiga ticks (Ixodes persulcatus) was carried out in a tick-borne viral encephalitis hotspot in the Irkutsk Region (Russia) using model samples of impregnated textiles. We demonstrated that permethrin- and cypermethrin-treated model samples have similar protective parameters in terms of maximum height reached by the tick when climbing up the treated textile (20.9-38.

Sympathetic System in Wound Healing: Multistage Control in Normal and Diabetic Skin.

In this review, we discuss sympathetic regulation in normal and diabetic wound healing. Experimental denervation studies have confirmed that sympathetic nerve endings in skin have an important and complex role in wound healing. Vasoconstrictor neurons secrete norepinephrine (NE) and neuropeptide Y (NPY).

First detection of tick-borne encephalitis virus in Ixodes ricinus ticks and their rodent hosts in Moscow, Russia.

Here, we report the first confirmed autochthonous tick-borne encephalitis case diagnosed in Moscow in 2016 and describe the detection of tick-borne encephalitis virus (TBEV) in ticks and small mammals in a Moscow park. The paper includes data from two patients who were bitten by TBEV-infected ticks in Moscow city; one of these cases led to the development of the meningeal form of TBE. Both TBEV-infected ticks attacked patients in the same area.

[INFLUENCE OF 29-40 AND 65-76 MCP-1 FRAGMENTS ON MYOCARDIUM MORPHOLOGY IN RATS AFTER T9CTHFMIA-R'FPFRFTTON].

Monocyte chemotactic protein-1 (MCP-1) is a chemokine that stimulates monocytes and macrophage migration into the sites of acute of chronic inflammation. Our study shows morphological changes in ischemic myocardium followed by the administration of two synthetic structural fragments of MCP-1 that are monocyte/macrophage migration inductor peptide IX and peptide X an inhibitor. Results show that peptides can change time points of the inflammatory response in myocardium.
