Mass spectral identification (in particular, in metabolomics) can be refined by comparing the observed and predicted properties of molecules, such as chromatographic retention. Significant advancements have been made in predicting these values using machine learning and deep learning. Usually, model predictions do not contain any indication of the possible error (uncertainty) or only one criterion is used for this purpose.

The possibility the hypercoagulation state occurrence raises nonlinearly together with such of the excised flap mass (% EFM), it exceeds 50% (high risk of hypercoagulation occurrence), when the EFM value constitutes 5.1% of the body mass.

With that objective there was determined the lipids content in a blood serum before and on a 14th day after abdominoplasty. In 73 patients (the main group) surgical interventions were performed on the organs of abdominal cavity, small pelvis and anterior abdominal wall with a simultant abdominoplasty, in 59 patients (a comparison group) abdominoplasty was not performed.

The condition of the profound femoral artery and the popliteal artery, especially in the zone of its trifurcation, is of the greatest significance for the decision on the volume of surgery. The carrying capacity of the collateral bed of the profound femoral artery in occlusion of the femoral artery was on average 284 ml/min.

All patients with CVI underwent either full-scope phlebectomy (64.

Altogether 112 patients over 50 years of age suffering from varicosity and chronic trophic ulcers of the distal limb segments were examined. The work was based on an analysis of the microcirculatory flow in lower limb tissues (laser Doppler flowmetry, BLF 21 system, Transonic Systems Inc., USA) and on the evaluation of tissue metabolism by measuring partial oxygen and carbon dioxide tension (percutaneous polarography; TCM-3 system, Radiometry Company, Denmark).

A comparative analysis of hemorheological indices was carried out in 105 patients with different variants of the course of critical ischemia of extremities and in 35 patients with intermittent claudication (as a reference group). Disturbances of the rheological properties of blood were revealed in the extremity muscles and in 62.4-68.

The authors analyze the results of conservative and operative treatment of 546 patients. The results of operative treatment (reconstructive operations on the arteries, osteo-trepanation) were shown to be considerably better in cases of critical ischemia than those of conservative treatment (infusion therapy, hemodilution, plasmapheresis).

Results of the postischemic test are of greater informative value in the noninvasive assessment of the functional state of microcirculation. The significance of the functional tests was particularly increasing in critical ischemia of the lower extremities.
