FATIGUE IN PATIENTS WITH LONG COVID.

Purpose of the study - to characterize the metabolomic profile in patients with fatigue developing within the Long COVID, during dynamic observation. 24 patients diagnosed with U09.9 "Condition after COVID-19 unspecified" were included in a prospective study.

[Methods of the videoendoscopic correction of the ureters strictures].

The Purpose Of The Study: a retrospective analysis of the results of patients treatment with ureteral strictures by evaluating the effectiveness of various methods of laparoscopic operations.

Materials And Methods: a retrospective analysis of the treatment of 30 patients operated in the Central Hospital of Civil Aviations from 2013 to the present time with strictures of all departments of the ureters, except the pelvic-ureteral segment (LMS), was performed. The study included 18 women and 12 men.

[Novel human embryonic stem cell lines C612 and C910].

Novel human embryonal stem cell lines C612 and C910 have been established from hatching blastocytes. Cells were cultivated in mTeST medium on mouse fibroblast feeder-layers. They express common pluripotent markers such as alkaline phosphatase, Oct 3/4, SEEA-4, Nanog, Rex1.

[Characterization of cultured murine mesenchymal stem cell line expressing GFP].

We have developed and characterized a murine mesenchymal stem cell line from the bone marrow of transgenic mouse C57BL ubiquitously expressing GFP. Immunostaining analysis revealed the presence of several markers typically found in fibroblasts such as smooth muscle cells actin in the form of stress fibrils and vimentin--the protein of intermediate filaments. These cells maintained capability to differentiate into adipocytes or osteoblasts under appropriate conditions.
