Objective: To study the impairment of cognitive functions in patients with different stages of the burnout syndrome (BS).
Material And Methods: 78 patients aged 25-45 years (average age 36.9±9.
Objective: To study the electroencephalographic manifestations of the various stages of burnout syndrome (BS).
Material And Methods: A quantitative analysis of the EEG of 131 patients, aged 25 to 45 years, with BS was performed. The control group included 143 people.
Objective: To study the effectiveness of two laser techniques clinically used to fragment renal stones: fragmenting technique (FT) and popcorn technique (PT).
Methods: Phantom stones were placed in a test tube filled with water, mimicking a renal calyx model. A Holmium:YAG laser was used for fragmentation using both techniques.
An in vitro model was used to predict short-term, laser-induced, thermal damage in canine prostate tissue. Canine prostate tissue samples were equipped with thermocouple probes to measure tissue temperature at 3, 6, 9 and 12 mm depths. The tissue surface was irradiated with a Nd:YAG laser in contact or non-contact mode for up to 20 s, using powers from 5 to 20 W.

Methods: We compared intermittent and continuous delivery of laser energy and studied the absorption of laser light by blood, intravascular temperatures in ex vivo human vein segments using an intravascular thermography catheter and heat dissipation in a model tissue using the Schlieren technique.
Results: Laser light is absorbed by blood and converted to heat leading to coagulation, vaporization and carbonization, and forming an isolating layer at the fibre tip.
