Abstract: Granulated beet pulp and wheat straw, first separately and then mixed in a weight ratio of 50/50%, underwent a pyrolysis process in a laboratory batch generator with process temperatures of 400 and 500 °C. The feedstock’s chemical composition and the pyrolysis products’ chemical composition (biochar and pyrolysis gas) were analysed. A synergistic effect was observed in the co-pyrolysis of the combined feedstock, which occurred as an increase the content of the arising gas in relation to the total weight of the products. and as a reduction of bio-oil content. The maximum gas proportion was 21.8% at 500 °C and the minimum between 12.6% and 18.4% for the pyrolysis of individual substrates at 400 °C. The proportions of the gases, including CO, CO2, CH4, H2, and O2, present in the resulting synthesis gases were also analysed. The usage of a higher pyrolysis final temperature strongly affected the increase of the CH4 and H2 concentration and the decrease of CO2 and CO concentration in the pyrolysis gas. The highest percentage of hydrogen in the synthesis gas, around 33%vol, occurred at 500 °C during co-pyrolysis.

Abstract: The article presents innovative concepts of the construction of ,,swimming buses” as a means of transport, both on land and on water. Amphibian is a dual-use vehicle. It can be used for various applications in the military area, rescue operations, as well as tourism. The article focuses on the description of the concept of an ,,swimming buses” in various countries. The success of each concept is largely based on research and development, although amphibious buses are already known, and vehicles of this type still have a long way to go through innovative development.

Abstract: (1) Background: Disturbances in the sphingolipid profile are observed in many diseases. There are currently no data available on the evaluation of sphingolipids and ceramides in cholelithiasis in children. The aim of this study was to evaluate the concentrations of sphingolipids in the sera of pediatric patients with gallstones. We determined their relationship with anthropometric and biochemical parameters. (2) Methods: The concentrations of sphingolipids in serum samples were evaluated using a quantitative method, ultra-high-performance liquid chromatography–tandem mass spectrometry. (3) Results: The prospective study included 48 children and adolescents diagnosed with gallstones and 38 controls. Serum concentrations of total cholesterol (TC); sphinganine (SPA); ceramides—C14:0-Cer, C16:0-Cer, C18:1-Cer, C18:0-Cer, C20:0-Cer and C24:1-Cer; and lactosylceramides—C16:0-LacCer, C18:0-LacCer, C18:1-LacCer, C24:0-LacCer and C24:1-LacCer differed significantly between patients with cholelithiasis and without cholelithiasis. After adjusting for age, gender, obesity and TC and TG levels, we found the best differentiating sphingolipids for cholelithiasis in the form of decreased SPA, C14:0-Cer, C16:0-Cer, C24:1-LacCer and C24:0-LacCer concentration and increased C20:0-Cer, C24:1-Cer, C16:0-LacCer and C18:1-LacCer. The highest area under the curve (AUC), specificity and sensitivity were determined for C16:0-Cer with cholelithiasis diagnosis. (4) Conclusions: Our results suggest that serum sphingolipids may be potential biomarkers in pediatric patients with cholelithiasis.

Abstract: The coexistence of inflammatory bowel disease (IBD) with pancreatic pathology is rare in children. A retrospective analysis of data from 1538 children diagnosed with IBD in 2014–2021 was conducted to determine the frequency and causes of pancreatitis and asymptomatic hyperlipasemia (HL) or hyperamylasemia (HA) in this group of patients. Among the 176 children (11.4%) with pancreatic involvement (PI), acute pancreatitis (AP) was diagnosed in 77 children (43.8%), and HA or HL was observed in 88 children (50.0%). Only a few patients were diagnosed with autoimmune or chronic pancreatitis (6.2%). PI was observed at the time of the IBD diagnosis in 26.1% of the cases. A total of 54.5% of the patients had moderate to severe IBD, and 96% had colonic involvement at the time of diagnosis of PI. Idiopathic PI was the most common (57%), followed by drug-induced PI (37%) and azathioprine (AZA). In patients with AZA-induced AP, the successful introduction of 6-mercaptopurine (6-MP) to therapy was noted in 62.5% of the children. Our results suggest that routine monitoring of pancreatic enzymes in patients with IBD should be performed, especially after the initiation of the AZA treatment. The presence of transient HA/HL in IBD does not necessarily indicate pancreatic pathology.

Abstract: Acute heart failure (AHF) is a life-threatening, heterogeneous disease requiring urgent diagnosis and treatment. The clinical severity and medical procedures differ according to a complex interplay between the deterioration cause, underlying cardiac substrate, and comorbidities. This study aimed to analyze the natural phenotypic heterogeneity of the AHF population and evaluate the possibilities offered by clustering (unsupervised machine-learning technique) in a medical data assessment. We evaluated data from 381 AHF patients. Sixty-three clinical and biochemical features were assessed at the admission of the patients and were included in the analysis after the preprocessing. The K-medoids algorithm was implemented to create the clusters, and optimization, based on the Davies-Bouldin index, was used. The clustering was performed while blinded to the outcome. The outcome associations were evaluated using the Kaplan-Meier curves and Cox proportional-hazards regressions. The algorithm distinguished six clusters that differed significantly in 58 variables concerning i.e., etiology, clinical status, comorbidities, laboratory parameters and lifestyle factors. The clusters differed in terms of the one-year mortality (p = 0.002). Using the clustering techniques, we extracted six phenotypes from AHF patients with distinct clinical characteristics and outcomes. Our results can be valuable for future trial constructions and customized treatment.
