Dyskinesias are involuntary muscle movements that occur spontaneously in Huntington's disease (HD) and after long-term treatments for Parkinson's disease (levodopa-induced dyskinesia; LID) or for schizophrenia (tardive dyskinesia, TD). Previous studies suggested that dyskinesias in these three conditions originate from different neuronal pathways that(More)
Multiple sclerosis (MS) is a multifactorial and polygenic disorder of the central nervous system, its development being under strong influence of T-helpers type I which produce anti-inflammation cytokines. Interleukin 12 (IL12) plays a key role in such polarization of the immune response. Genotyping for polymorphism of the IL12B gene in the 3'-untranslated(More)
A study of parameters of oxidant and antioxidant systems has been carried out in 79 patients with multiple sclerosis (MS) and in 75 mentally and physically healthy subjects. Parameters of intensification of lipids peroxidation and conditions of enzymatic and non-enzymatic parts of antioxidant system (AOS) have been analyzed in different clinical forms and(More)
Choline-positive neuroprotectors citicoline and choline alfoscerate decreased blood concentration of protein S100 in clinical trial on 52 patients in the first days after acute ischemic stroke. Neuroprotective therapy has also produced stabilization of blood-brain barrier.
The influence of vinpocetine (cavinton) on endothelium function in 87 patients with chronic cerebral ischemia has been studied. Vinpocetine exerts an endothelium protective effect which appears as a partial renewal of endothelium-dependent vasodilatation and inhibition of rejection of Willebrand factor during arteriovenous occlusion test. Leveling of(More)
Multiple sclerosis (MS) is a serious, incurable neurological disease. In 2009, the ANZgene studies detected the suggestive association of located upstream of CD40 gene in chromosome 20q13 (p = 1.3×10(-7)). Identification of the causal variant(s) in the CD40 locus leads to a better understanding of the mechanism underlying the development of autoimmune(More)
Immune mechanisms play a pivotal role in the development of multiple sclerosis (MS). Vitamin D is an important biological immunoregulator acting through receptors of immunocompetent cells. Genotype and haplotype frequencies for VDR polymorphisms in a case-control study of MS have been investigated. Results have shown an association of the VDR T/t variant(More)
A replicative association analysis of Alzheimer’s disease (AD) was carried out for 15 genetic markers that have been associated with cognitive disorders in genome-wide association studies. In the Russian population, AD was associated with CSMD1 rs2616984 (OR = 1.50, 95% CI 1.07–2.09, p-value = 0.018) and, potentially, with NOTCH4 rs313296 (OR = 1.53, 95% CI(More)
Objective. To study the efficacy and safety of phenotropil as add-on to treatment with standard antiepileptic drugs (AED) in patients with symptomatic locally-induced epilepsy (SLIE). Material and methods. Double-blind placebo controlled randomized trial was carried out. Ninety patients were treated by phenotropil dose (100 or 200 mg) or placebo. MMSE,(More)
The influence of vinpocetine, pentoxifylline and enalapril on endothelium functions has been studied in a group of in 172 patients with chronic brain ischemia. The endothelium-protective effect of drugs was manifested as the inhibition of the Willebrand factor output during arteriovenous occlusion test and as the renewal of endothelium-depended(More)
