Chemical insight into pros and cons of coffees from different regions.

The main aim of this work was to study the chemical composition of eighteen ground coffees from different countries and continents with regard to the content of hazardous substances as radioactive elements (K, Ra, Ra, U, U and Cs), metals, including heavy metals, aluminum and some microelements (V, Cr, Mn, Fe, Co, Ni, Cu, Zn) as well as substances that have a positive effect on human health and well-being (polyphenols, proteins, fats and caffeine). The tests were carried out before and after the brewing process using the following techniques: gamma and beta spectrometry, a microwave-induced plasma optical emission spectrometer (MIP-OES), gravimetric method, UV-Vis spectrophotometry as well as thin-layer chromatography. The leaching percentage of certain elements/compounds in coffee infusions was also measured.

Understanding the synergistic interaction between a 1,3,4-thiadiazole derivative and amphotericin B using spectroscopic and theoretical studies.

We present a comprehensive spectroscopic study supported by theoretical quantum chemical calculations conducted on a molecular system (4-(5-methyl-1,3,4-thiadiazol-2-yl)benzene-1,3-diol (C1) and the antibiotic Amphotericin B (AmB)) that exhibits highly synergistic properties. We previously reported the strong synergism of this molecular system and now wish to present related stationary measurements of UV-Vis absorption, fluorescence, and fluorescence anisotropy in a polar, aprotic solvent (DMSO and a PBS buffer), followed by time-resolved fluorescence intensity and anisotropy decay studies using different ratios of the selected 1,3,4-thiadiazole derivative to Amphotericin B. Absorption spectra measured for the system revealed discrepancies in terms of the shapes of absorption bands, particularly in PBS.

Xenobiotics recovery from plasma using solid phase extraction with C-18 sorbent - The reasons of literature discrepancies.

Solid phase extraction (SPE) is one of the most popular methods of preparing plasma samples before determining the xenobiotics they contain. The present paper shows that the recovery degree of xenobiotics from plasma samples using SPE with C18 sorbent strongly depends on their storage time and temperature. While xenobiotics can be isolated and recovered in 100 % from fresh plasma samples under optimal conditions of the SPE procedure, their SPE recovery degree from stored plasma is lower.

Adsorption and wetting properties of biosurfactants, Trtions and their mixtures in aqueous and water-ethanol environment.

Adsorption of rhamnolipid (RL) and surfactin (SF) as well as their mixtures with Triton X-100 (TX100) and Triton X-165 (TX165) at the solution-air (S-A), PTFE (polytetrafluoroethylene)-S, PMMA (poly (methyl methacrylate))-S, Q (quartz)-S, PMMA-A, and Q-A as well as their wetting properties regarding the surface tension of the PTFE, PMMA and quartz and its components and parameters were discussed using the literature data. The mutual influence of biosurfactants and Tritons on the S-A, PMMA(quartz)-A and PTFE(PMMA, quartz)-S interfaces tensions was considered in terms of their adsorption at these interfaces for both aqueous and water-ethanol solutions of the biosurfactant mixtures with Tritons. For this purpose there were used different methods on the basis of which the S-A, PMMA(quartz)-A and PTFE(PMMA, quartz)-S interface tensions can be predicted and/or described in the function of concentration and composition of the mixtures.

Challenges ahead: Exploring external barriers to self-determination in individuals with intellectual disabilities.

The extent to which individuals with intellectual disabilities (ID) can exercise self-determination in their adult lives is largely influenced by various contextual factors, including their family environment, the institutions they interact with, and the legal and social conditions in which they function. In this study, we aimed to explore the lived experiences of people with ID in the context of the environmental challenges they face on the path to self-determination. To achieve this goal, we conducted an inclusive study involving co-researchers with ID.
