This work demonstrates some results of the successful experience using wearable devices for multimodal optical diagnostics microcirculatory-tissue systems both in clinical practice and conditions a Space experiment. The approach based on simultaneously applying minimum 2 diagnostic methods, example, laser Doppler flowmetry fluorescence spectroscopy, allows analysing blood flow metabolic process...

Two hundred direct pulp capping procedures were conducted in the present study. One hundred of them were performed with the CO2 laser, and 100 were conducted conventionally as a control by using a calcium hydroxide preparation. Follow-up examinations were performed after 1 wk and monthly for 12 months after treatment. Thermal tests were used for vitality assessments and laser Doppler flowmetry ...

Tendinopathy is of distinct interest as it describes a painful tendon disease with local tenderness, swelling and pain associated with sonographic features such as hypoechogenic texture and diameter enlargement. Recent research elucidated microcirculatory changes in tendinopathy using laser Doppler flowmetry and spectrophotometry such as at the Achilles tendon, the patellar tendon as well as at...

Sucralfate possesses site protective and cytoprotective actions and heals ulcers effectively, but its effect on gastric mucosal blood flow is unknown. Using an ex vivo gastric chamber preparation, we studied the effect of sucralfate on gastric mucosal blood flow in rats by laser doppler flowmetry. Under both fasting and fed states, measurements of gastric mucosal blood flow and damage were made...

BACKGROUND: When measuring skin blood perfusion with laser-Doppler methods in a limb, a non-zero perfusion is sometimes registered even when the arterial inflow to, and venous outflow from the site of measurement is arrested using proximal cuff compression pressures well in excess of systolic blood pressure. This residual signal, known as the biological zero (BZ)1-7, is present to some extent w...
