AB  - The knowledge of the structural and chemical properties of biochars is decisive for their application as technical products. For this reason, methods for the characterization of biochars that are generally applicable and allow quality control are highly desired. Several methods that have shown potential in other studies were used to investigate two activated carbons and seven biochars from different processes and feedstock. The chars were chosen to cover a wide range of chemical composition and structural properties as a hardness test for the analytical methods used in this study. Specific problems connected with the pretreatment of samples and drawbacks of some methods for some types of chars could be identified in an integrated consideration of the results from different methods. None of the spectroscopic methods was found to be suitable for the quality control of all types of chars. The most valuable results were obtained by chemical analysis that, however, required the complete determination of the main elements, including that of oxygen, and of inorganic components for adequate results. The combination of X-ray photoelectron spectroscopy (XPS) and FT-IR spectroscopy allows a rough characterization of surface functional groups, but cannot discriminate aliphatic and aromatic OH groups. FT-IR might be a suitable method for the quality control of biochars made at lower temperature. The results of Raman spectroscopy did not well correlate with the amount of sp2 hybridized carbon determined by XPS. A better correlation of XPS data was found with the electrical polarization determined by the method of spectral induced polarization that was used for the first time in conjunction with extensive analytical characterization. © 2022 Ilić et al.

AB  - Bioremediation potential of bacteria and fungi isolated from sediment samples from an alluvial formation of the Danube (wastewater channel) of the Pancevo Industrial Zone (Serbia) was investigated earlier. (Ilic M., Antic M., Antic V., Schwarzbauer J., Vrvic M. and Jovancicevic B., Investigation of bioremediation potential of zymogenous bacteria and fungi for crude oil degradation. Environmental Chemistry Letters (submitted)) In this paper, results concerning bioremediation potential of bacteria and fungi isolated from soil samples will be presented. Total isolated microorganisms were divided into three parts and sown in an appropriate medium. Actidione fungicide was added to one innoculum so that only bacteria propagated in it. Streptomycin antibiotic was added to a second innoculum, wherein fungi propagated. The third portion (with no additives) contained consortium of fungi and bacteria. Paraffinic petroleum, in inorganic medium in phosphate puffer, was a substrate for assessment of bioremediation potential of the mentioned microorganisms. The experiments of the simulated oil biodegradation lasted 30, 60 and 90 days. Extracts were isolated from the samples with chloroform liquid-liquid extraction. Extracts were fractionated by column chromatography. Alkane fraction was analyzed by gas chromatography-mass spectrometry (GC-MS) techniques.

AB  - Malnutrition and inflammation are associated with end-stage renal disease (ESRD). Interleukin (IL)-6 and tumor necrosis factor alpha (TNF-alpha) powerfully predict death from cardiovascular disease. The aim of our study was to establish an association between markers of inflammation and parameters of malnutrition in patients on hemodialysis. The study population consisted of 42 hemodialysis patients with different parameters of malnutrition. Blood samples were taken after an overnight fast, and plasma lipid profiles (total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides) were measured by using conventional enzymatic methods. Serum urea and creatinine levels were also measured by routine procedures. Plasma high-sensitivity C-reactive protein level (hs-CRP), TNF-alpha, and IL-6 were measured by enzyme-linked immunosorbent assay (ELISA). Standard Doppler echo examinations were used to determine plaque on carotid arteries, and end-diastolic diameter (EDD) and ejection fraction (EF) were measured by echocardiography. Malnourished patients exhibited significantly greater evidence of cardiovascular disease and carotid plaques. Factor (principal component) analysis indicated 6 latent factors with 67.5% of the variance explained within all investigated parameters. Cluster analysis was used to distinguish the inflammatory markers and the nutritional markers from other parameters and to visualize similarities between variables. In summary, this cross-sectional study in hemodialysis patients found a high prevalence of malnutrition, inflammation, carotid plaques, and cardiovascular disease. Malnourished dialysis patients are more often found with cardiovascular disease and carotid plaques. In addition, these patients have higher levels of inflammatory cytokines, which may partly explain the elevated risk for atherosclerotic vascular disease.
