METHOD FOR DETERMINING SUBPOPULATION COMPOSITION OF SKIN CELLS AND OBTAINING SKIN CYTOIMMUNOGRAM

FIELD: medicine.

SUBSTANCE: method for determining the subpopulation composition of skin cells and obtaining the skin cytoimmunogram comprises sampling a skin biopsy specimen to a depth of 2 mm, homogenizing the tissue in a 0.9% aqueous solution of sodium chloride at a temperature of +23…+25°C, extracting the homogenate, filtering the homogenate through an inert filtering partition with a pore diametre of 20 mcm, centrifuging the homogenate at 400 g for 5 minutes at a temperature +23…+25°C. After centrifugation, the viability of the skin cells is determined, the skin cells are incubated for 20 minutes with monoclonal antibodies fluorochrome-labeled for flow cytometry, phenotyping of the skin cells is carried out, the number of skin cells of a specific phenotype - skin cytoimmunogram - are determined: keratinocytes CD49f+, among them activated CD49f+HLA-DR+; fibroblasts (fibrocytes) CD45-CD14-CD44+, among them activated CD45-CD14-CD44+CD80+; mast cells CD249+, among them activated CD249+CD63+; monocytes (macrophages) CD45+CD14+, among them activated CD45+CD14+HLA-DR+; intra-epidermal macrophages CD207+, among them activated CD207+CD80+, CD207+HLA-DR+, CD207+CD80+HLA-DR+; endothelial cells CD146+, among them activated CD146+CD34+, CD146+HLA-DR+, CD146+CD54+, CD146+CD54+HLA-DR+; lymphocyte populations: T-lymphocytes CD45+CD3+, T-helpers CD45+CD3+CD4+CD8-, T-suppressors CD45+CD3+CD4-CD8+, B-lymphocytes CD45+CD3-CD19+, NK-lymphocytes CD45+CD3-CD16+CD56+.

EFFECT: application of this method allows to make a quantitative and functional characteristic of all the skin constituent elements for use in diagnosis.

Nature-Friendly Strategy for Growing Innovation: the Placental Approach
Nature-Friendly Strategy for Growing Innovation: the Placental Approach

The creation of fertile innovative ecological environment in the country is constrained by barriers of a conceptual nature. The article identifies four groups of such barriers. The authors propose a strategy for overcoming them based on a comparison of functions necessary for the innovative development of social practices and the natural mechanisms of a new life birth. This allows us to formulate a number of pragmatic recommendations for creating an innovative eco-environment for a wide range of industries. By analogy with natural dynamics of obstetrics, the approach is called placental

Keywords: Innovation, innovation infrastructure, acceleration, eco-environment, placenta, development.

Чай как способ передачи культурного кода
Чай как способ передачи культурного кода

Вот уж чего в любой экспедиции должно быть с избытком, так это чая и юмора (как вариант, сойдет кофе и хорошее расположение духа). Но, горячая кружка ароматного чая творит чудеса, особенно за вечерними посиделками и разговорами об увиденном, пережитом и затронувшем.

Культура – надбиологическая совокупность феноменов
Культура – надбиологическая совокупность феноменов

Остаются считанные дни времени пребывания экспедиции Живая Параллель в Перу. Изучив тексты, увидев множество подтверждений мифов и обоснованности сведений об инках, встретившись с представителями разных социумов, возникших вследствии испанского завоевания, настало время разделить реальную жизнь с последними потомками инков. Благо, это оказалось реальностью, поскольку наш проводник Элвис, родом из народности кечуа, являющейся прямым наследником культурных традиций инков, видя нашу искреннюю (не туристическую) потребность пожить в культуре, любезно пригласил посетить его деревню.

Masks. Part two: faces of time.

Even to the horrors of war, the doctor gets used to much faster than an ordinary person, as well as soldiers, after two or three weeks already much without noticing and assessing what is happening, as a matter of course. What can we say about the events taking place during the expedition, when the phenomenon recorded by the photo may contain a different depth of meaning, often understood only after some time. The expedition Live Parallel, organized by Professor A. G. Teslinov in Peru and Bolivia and ended 2 months ago, was not an exception for me. Read more...
