AB  - Peroxisome proliferator-activated receptor alpha (PPARα) is crucial in regulating lipid metabolism. Clinically, PPARα is significant as a possible therapeutic target for a variety of human disorders, including cardiovascular, neurological, and metabolic syndromes. The wide range of natural compounds provides great opportunities for new approaches in targeting PPARα. Carotenoids, a large class of natural compounds, have been recognized as PPARα agonists. Tomatoes (Solanum lycopersicum) are one of the most widely grown crops in the world and contain compounds that improve lipid metabolism. Since there is no data on tomato carotenoids as PPARα agonists in this study, we focused on searching carotenoids from tomatoes as possible PPARα agonists. The Solanum lycopersicum carotenoids from Carotenoids Database were in silico screened using a combined protocol with the Electron-Ion Interaction Potential/Average Quasi Valence Number (EIIP/AQVN) filter and molecular docking to find the most promising candidate compounds. The best resulting compounds may have the promise to be further developed as candidates for PPARα agonists.

AB  - The organic pigments offer promising opportunities for developing new sustainable electrode materials for lithium batteries. Some of them have been identified as cathode material with very encouraging reversible lithium ion storage characteristics. One of them is a naturally occurring purpurin extracted from the Madder plant (Rubia tinctorum) for which we confirmed this good electrochemical behavior by cyclic voltammetry. One of the strategies towards obtaining materials with even better characteristics is a structural modification of already existing pigments. Building a theoretical model that could predict the redox properties of these new compounds can be very useful towards achieving that goal. In order to build a 3D QSAR (quantitative structure–activity relationship) model for material redox potential prediction, 9 organic pigments with known redox potentials were extracted from the literature. Based on molecular interaction field (MIF) probes we calculated standard GRIND (grid-independent) descriptors and constructed following principal PLS (partial least squares) model. By validation with the literature data, but also with the obtained experimental data for purpurin, this model proved very reliable in predicting the redox potential. A comparison was also made with the machine learning model that was formed in parallel.

AB  - An intriguing step of the Bray–Liebhafsky oscillatory reaction, that is, iodine oxidation with hydrogen peroxide, was examined. This process is characterized by enormous stochasticity of reaction induction times in the presence of mild mixing. In the present investigations, it was found that even in the presence of mixing, stochasticity is seriously reduced with simple glass powder addition. Using transparent glass, standard deviations changed from 184.9 to 10.6 min for 19 °C, and from 128.2 to 1.9 min for 27 °C. Repeating experiments with amber glass further confirmed those results as standard deviations changed from the mentioned ones to 8.7 min for 19 °C and to 2.5 min for 27 °C. Inert glass particles enhanced heterogeneous nucleation of oxygen formed in chemical reactions. Together with the previous analysis of the involved kinetic barrier of the whole reaction, it is an additional strong evidence of a possible energetic coupling between nucleation of glass cavities and chemical reactions. Such processes are usually neglected and may considerably change the investigations of the reaction mechanisms in other complex systems. Reaction was followed by the potentiometric method at 19 and 27 °C. The adjusted stopped-flow titration method was used in order to confirm the high degree of iodine to iodate conversion in the presence of nucleation centers.

AB  - This paper describes determination of gross alpha and beta activity in tap waters used for drinking in Serbia. 19 samples from different cities were investigated. Method used for sample preparation was EPA 900.0 and activity was determined by proportional counter. Obtained gross alpha activity was in range MDA-0.318 Bq/l, while gross beta activity was in range MDA-0.370 Bq/l. With these values individual dose criterion of 0.1 mSv/year will not be exceeded. Based on the fact that all investigated samples met the criteria given in Serbian rule book, further analyzes were not conducted.
