In landscape and biogeographic studies, the assessment of the photosynthesis process, which a ects the possibility of determining the productivity of phytocenoses, calculating the growth of phytomass, is of particular relevance. The use of unmanned aerial vehicles (UAVs) to evaluate the leaf surface index (LAI) is gaining more and more scope over time due to their low price, high operational e ciency and accuracy. The basis for determining LAI is a model for the slit fraction, theoretically estimated using the Bera-Booger- Lambert law. The possibility of determining the LAI of vegetation using a UAV, on board of which either a lidar or a multispectrometer can be installed, is analyzed. In the rst problem, LAI is determined by calculating the logarithm of the slit function (fraction) multiplied by the cosine of the scanning angle and divided by the attenuation coe cient. The second problem uses the existing correlations between known vegetation indices and LAI. Empirical statistical regression models may be suitable for determining LAI after determining various vegetation indices. Based on the results of multispectral measurements, it was found that the LAI determination technique based on measuring the intensity of rays that passed through the crown of plants leads to highly noisy estimates. For this reason, it was decided to use the slit fraction (GF), while using the experimentally established fact that when multiplying the logarithm of the vegetation index by the height of the crown, this correlation is signi cantly enhanced. To increase the reliability of the obtained LAI values, it is proposed to use the average integral value of this indicator, calculated by composing and calculating an optimization variational problem containing an additional restrictive condition. At the same time, it is possible to solve both problems to the maximum, i.e. it becomes possible to increase the signal-to-noise ratio of the calculated value of the LAI index. In both optimization calculation procedures, there are generalized indicators that have di erent physical meanings.

In order to achieve high sports results, a comprehensive study of the athlete’s body is necessary.The morphofunctional study is the most informative and accessible. However, the somatotype-related functionalstate of the cardiovascular system of athletes remains insufficiently studied. The purpose of the research: Todetermine the indicators of the cardiovascular system of athletes in response to physical exertion, dependingon the somatotype according to Reese-Eysenck. An anthropometric and functional study of the cardiovascularsystem of 49 athletes of the highest sports skill engaged in freestyle wrestling at the Sakha Republic’s Center forTraditional Sports was conducted. The Reese-Eysenck index was used to determine the somatotype. Functionalexamination of the cardiovascular system included blood pressure measurement and pulse counting at rest, then 1and 2 minutes after exercise. The exercise consisted of a full squat with arms outstretched with a frequency of 20squats in 30 seconds. In order to determine the tolerance of physical activity, the Roufier index was calculated. Theadaptive potential of the cardiovascular system is determined using the index of functional changes. Somatotypingby the Reese-Eysenck index among the examined athletes revealed that a significantly large proportion of theexamined individuals had an athletic somatotype. In pyknics, significantly large indicators of body weight and thetransverse diameter of the chest were recorded. A functional examination of the cardiovascular system with theuse of physical activity revealed a significantly greater increase in systolic blood pressure after 1 and 2 minutesand heart rate 1 minute after physical activity in individuals with the pyknic somatotype compared with others.The analysis of the results of the index of functional changes of athletes depending on the somatotype revealedthe stress of the cardiovascular system function only in athletes of the pyknic somatotype. The obtained resultsindicate that the training process should be selected individually, taking into account the somatotype of an athlete,since among pyknics there are people with stress of the cardiovascular system with good results of physicalactivity tolerance according to the Roufier index.

The purpose of the study was to investigate the incidence of in-stent restenosis after the firstpercutaneous coronary intervention (PCI) in patients with recurrent coronary event and to evaluate the influenceof comorbidity factor. The analysis of 1,198 electronic patient histories from the Department of EmergencyCardiology with Anesthesiology-Resuscitation Group (ECA with ARG) of the Republic’s Vascular Center,“Republic’s Hospital No. 2 – Сenter Of Emergency Medical Aidһ, for the year 2022 was carried out. Accordingto the results of the analysis, 77.5 % of 1,198 patients of the Department were treated for acute coronary syndrome(ACS), out of which 62 % were diagnosed with myocardial infarction. The ACS patients underwent PCI in 78.5 %of cases. Restenosis of the previously implanted stent within 5 years was detected in 2.7 % of patients with ACS.Patients with stent restenosis were predominantly men (84 %) aged 60 – 74 years (76 %). Among the studied60-74-year-old patients, in 68.4 % of the cases, repeated hospitalizations were related to stent restenosis in oneyear or more after PCI. Recurrent coronary events in 36 % of patients were manifested as ST-segment elevationmyocardial infarction (STEMI); 24 % experienced non-ST-segment elevation myocardial infarction (NSTEMI);and 40 % of the patients with stent restenosis were diagnosed with unstable angina. Drug-eluting stents were usedin 84 % of the cases undergoing PCI; 56 % of the patients received PCI with two or more stents. Multivesselcoronary artery lesions occurred in 80 % of the patients. All patients with restenosis had arterial hypertension,20 % were obese (BMI≥30 kg/m2), 16 % had type 2 diabetes mellitus, and 4 % had impaired glucosetolerance. Target cholesterol LDL levels were not achieved in 72 % of the patients. According to transthoracicechocardiography data, 28 % of the patients with stent restenosis had left ventricular ejection fraction less than40 % according to Simpson. Among the comorbidities, chronic obstructive pulmonary disease was found in everythird (32 %) patient; chronic kidney disease was seen in 40 %.

In order to assess the safety and efficacy of intraoperative local thrombolysis followed by reconstructionand plasty of the vessel, we studied the immediate results of treatment of 28 patients with thrombotic occlusionsof shunts and arteries of the lower extremities. Recently, the inflammatory theory of atherosclerosis has attractedmuch attention. The inflammatory process in atherosclerosis is observed from the early development of lesions inthe vessel wall to the destabilization and destruction of atherosclerotic plaques. The thinning of the fibrous plugand the expansion of the lipid core in it are considered important factors of destabilization leading to damage toatherosclerosis and thrombotic occlusion. The causes leading to the development of inflammatory processes inatherosclerosis are currently studied extensively, but not exhaustively. The indication for thrombolytic therapy wassevere ischemia of the lower extremities with a thrombosis duration of 3 days to 3 months and minor symptomsin the distal arterial bed. Local thrombolysis was performed using Urokinase Medak and Fortelizin, restoration ofblood flow was achieved in 25 patients. Early recurrent arterial thrombosis at the site of reconstruction developedin three patients. In the long term, the operated limb was amputated in two patients. The study showed that local intraoperative thrombolysis together with arterial reconstruction is a fairly safeand effective method for the treatment of thrombotic occlusions of the arteries of the lower extremities, shunts andprostheses at different stages of thrombus formation. This method may be a good option when selective catheter-guided thrombolysis is in doubt due to inadequate distal blood flow on angiography.

Epilepsy is one of the most common diseases of the nervous system in children. According to WHO,more than 50 million people worldwide suffer from epilepsy. It is estimated that the proportion of the generalpopulation with its active form (that is, with recurrent seizures and the need for treatment) currently ranges from 4to 10 per 1,000 people. Globally, 2.4 million people are diagnosed with this disease every year. In Russia, epilepsyaffects more than 1 million people. The analysis of statistical data on the prevalence and incidence of epilepsy inchildren in the Republic of Sakha (Yakutia) was carried out. In Yakutia, the first epidemiological study of epilepsyin the pediatric population was conducted in 1985 by E.A. Krivogornitsyna. As a result of the survey, data wereobtained on 322 children who were registered at the dispensary with neurologists and psychiatrists in 32 districtsof the republic and the city of Yakutsk. According to the study of the epidemiology of epilepsy in children in 2004 (Baisheva G.M., 2004), the prevalence of epilepsy was 5.2 per 1,000 children of the Republic of Sakha (Yakutia),and the primary incidence was 114 per 100,000 children. Prevalence of epilepsy in children under 14 years ofage in 2020 was 5.4 per 1,000 population, the primary incidence was 50 per 100,000 population. On average,from 2010 to 2020, the primary incidence of epilepsy in children is 80 per 100,000 population. The prevalenceof epilepsy in adolescents aged 15 – 17 years averaged 10.4 %. The average value of primary morbidity in thisgroup of children was 140 per 100,000 population. The organization of comprehensive medical care will make itpossible to form a strategy for the management of epilepsy patients at the municipal and republic levels.

The article presents data on the frequency of risk factors for cardiovascular diseases in adolescents.A statistical analysis was also conducted to determine the correlations between the risk factors when an individualhas multiple risk factors. The following risk factors for cardiovascular diseases, already occurring frequentlyin adolescence, were evaluated: high blood pressure, overweight, elevated cholesterol levels, carbohydratemetabolism disorders, low physical activity, eating disorders, and stress perception. A total of 712 adolescents aged15 –16 years were examined, including 360 girls and 352 boys, residing in the city of Yakutsk, Sakha Republic(Yakutia). The study revealed that among adolescents, low physical activity showed the highest frequency amongthe risk factors, followed by others in descending order: restrictive eating behavior, high cholesterol and glucoselevels, overweight and obesity, and high stress perception. The differences found were based on gender, with boysbeing more susceptible to obesity. Correlation analyses using Spearman’s (rs) and Pearson’s (rp) coefficients andPearson’s chi-square test were used to identify relationships between risk factors for cardiovascular diseases.The analysis showed that high blood pressure is associated with adolescents who have high body mass index.Gender-based analysis showed that girls are more prone to arterial pressure disorders and elevated cholesteroland glucose levels.
