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.
The only one of the three places on the planet covered with snow on the equator is Mount Irian Jaya. Along with other mountains it seizes the Baliem valley around the perimeter while I’m seized with the feeling of being carried to the primeval world...
Оказаться в Лиме для всех участников экспедиции Живая Параллель – знаковое событие, именно здесь стартует исследование закономерностей культуры, о которой, согласитесь, у нас очень смутные представления. А иначе и быть не могло: инки, испанцы, индейцы и... метисы - много разнообразных культур и одна на всех Культура Перу, в которой нам предстоит побыть ближайшие недели.
After twelve years of successful expeditionary experience, the LIVING PARALLEL broadens the horizon of its search. Since 2019, the program of continuous round-the-WORLD STUDY of the possibilities of Culture as a "second nature" and man in local cultures has been continuing.
Stage 1 has already taken place in New Zealand, and the next stage is ahead – South and Central Africa – 2021
A good leader must combine several important qualities at once and perform many functions: competently manage the budget, be a mentor for subordinates and a friend to his clients, create a working atmosphere, set an example, solve problems, set tasks ... Simply put, to be the center of your business .
But there is one more duty that among others is usually not called: if the boss defaults, encourages and directs, he must also punish, and sometimes - severely. Of course, this is very few people enjoy, but it is - as an integral part of the leadership process, like the others.
About what misdemeanors of subordinates deserve indulgence, and which ones can not be forgiven in any case, and also what will be the most serious punishment for a doctor working in a medical institution, we talked with the "Aesthetic Guide".
