MEMBRANE-RECEPTOR COMPLEX DYSFUNCTION AS A NEW TARGET FOR THE NEUROTROPHIC THERAPY OF ISCHEMIC STROKE
Get PDFThe aim of the study was the β-adrenergic activity of peripheral blood erythrocyte membranes in the acute period of ischemic stroke (IS).
Peripheral blood erythrocytes are the most informative biological tissue for studying many pathogenetic mechanisms, and the work of their membrane-receptor complex (MRC) can very well reflect the functional state of the whole organism, one of the most important criteria for assessing is the adrenergic activity of cytoplasmic membranes in the pathogenesis of IS.
This study solves the problem of the finding of the features of changes in the adrenoceptors system in the acute period of IS in the dynamics of the treatment of humans cryopreserved cord blood serum (CCBS).
The main scientific results: the obtained results indicate a reduced ability of adrenoceptors (ARs) on erythrocyte membranes to bind blockers due to the desensitisation effect, which is observed from the 1st day of the disease.
In the onset of IS, there is a significant increase in the values of β-adrenergic activity of membranes (β-ARM) of erythrocytes in 2.4 times compared with the control. Maximum levels of the indicator (42.43±3.64 CU) are observed in patients with initially severe disease, which indicates significant stress of the sympathoadrenal system (SAS) in these patients.
On the 10th day of the disease, there was a decrease in β-ARM relative to the values obtained during hospitalisation. Still, comparing the value of the indicator on the 10th day of IS in both groups, there was an apparent, more significant decrease in β-ARM in the 2nd group of patients, which additionally received CCBS.
The use of CCBS contributes to a more pronounced degree of recovery in neurological functions (6.9%) and faster stabilisation of the structure of MRCs in erythrocytes in the form of reducing the values of β-ARM to 16.61±2.86 CU (p<0.05).
The area of practical use of the research results: the results of the study can be used to diagnose and treat of the IS.
An innovative technological product: A comprehensive approach to assess the β-ARM of peripheral blood erythrocytes in patients with IS by determining the degree of changes in osmotic resistance of erythrocytes (ORE) under the action of adrenergic drugs (AD) is informative and can be used to diagnose of IS. The use of neurotrophic factors is a potentially new method of treating this pathology.
Scope of application of the innovative technological product: in the clinical practice of neurological departments for the treatment of patients with stroke

E-LEARNING EDUCATION SYSTEMS EFFICIENCY RATING MODEL
Get PDFE-learning support system is a mandatory attribute of the modern educational process. What criteria laid down in its development depends largely on the effectiveness of further applications of the entire system. The evaluation of the training effect depends on various factors, each of which is determined by many interrelated criteria. In conditions when there are resource constraints (financial or time), the actual becomes the problem of determining the factors (criteria) that have the most significant impact on the effectiveness of e-learning system. The article offers step-by-step method of constructing a model that allows to represent the original set of criteria of evaluation of the training effect of the use of e-learning system in the form of appropriate level of influence grades. Introduces the concept of configuration vector and weight vector configuration, ranking models and based on them describe the procedure of finding the most substantive relationship between the criteria. Provides formulas to calculate appropriate weighting factors for current connections. An indicator of the importance of communication is the change of vector configuration, ranking models, and quantitative characterization of the dominant relations is defined as the difference between the weight coefficients of the respective vectors of the configuration options ranking of the analyzed models. The obtained results can be applied when developing holarchical models, support systems, e-learning, which allow us to quantitatively justify decisions regarding the choice of appropriate alternatives
