    T-lymphocytic enteral leiomyositis (T-lel) is a rare disorder causing chronic intestinal pseudo-obstruction (CIPO), with cases predominantly being reported in the field of veterinary and pediatric medicine. Here, we present a case of T-lel-associated CIPO in an adult female, who initially presented with a paralytic ileus 2 weeks after a common gastroenteritis. The histological diagnosis was established through full-thickness bowel biopsy, exhibiting a dense lymphocytic infiltrate in the lamina muscularis of the intestinal wall. This case shows that T-lel can be a cause of chronic intestinal pseudo-obstruction not only in children but also in adults. A subsequent induction of an immunosuppressive therapy with steroids, azathioprine, and ultimately TNF-alpha-inhibiting antibodies led to a slow recovery and stable disease

The main aim of the research is to evaluate the possibility of woody biomass and peat pyrolysis due to heat from the organic part decomposition of the raw material. Objects: peat samples from two deposits of the Tomsk region, promising for energy development, - Sukhovsky and Arkadievsky, as well as wood waste of two types - chips and sawdust. Methods: physical experiment and differential thermal analysis. Thermotechnical characteristics of woody biomass determined by the methods SS R 56881-2016, SS 33503-2015 and SS R 55660-2013; thermal characteristics of peat - using the SS 11306-2013, SS 113052013 and SS R 55660-2013. Calorific value of raw materials determined in the bomb calorimeter ABK-1 (RET, Russia), the elemental composition is determined by the analyser Vario Micro Cube (Elementar, Germany) taking into account the carbon dioxide content of the carbonates, established by volumetric method according to SS 13455-91. Results. The authors have established the optimal parameters of pyrolytic processing for various types of biomass, such as pyrolysis temperature and moisture of the raw material. The optimum temperature for pyrolysis of wood waste in the air-dry state is 400 Β°C, at which the total thermal effect is maximum and equal to 36,3 kJ/kg for sawdust and 78,8 kJ/kg for wood chips, for sukhovskoy peat at 500 Β°C total heat effect is equal to 149,7 kJ/kg. The maximum values of moisture, providing coverage of heat costs due to the heat of exothermic reactions, at these pyrolysis temperatures were 10 % for wood waste and 14 % for sukhovskoy peat. The value of the total thermal effect of arkadievsky peat pyrolysis even in the dry state has a negative value
