AB  - Aflatoksini su značajan problem u oblasti bezbednosti hrane i rizika po zdravlje ljudi. Gama zračenje uništava opasne zagađivače u hrani kao što su bakterije, virusi, gljivice, pesticidi i toksini. U ovoj studiji je korišćeno gama zračenje da bi se smanjila količina aflatoksina u mleku. Rezultati su pokazali smanjenje aflatoksina u mleku za 9 % - 35,26 % u poređenju sa kontrolnim uzorkom. Smanjenje koncentracija aflatoksina u mleku nije proporcionalno primenjenoj dozi grama zračenja usled zgrušavanja mleka.
AB  - Aflatoxins are a significant problem in the field of food safety and risk to human health. Gamma irradiation destroys dangerous contaminants in foods such as bacteria, viruses, fungi, pesticides, and toxins. In this study, we used gamma radiation to reduce the amount of aflatoxins in milk. The results showed a 9 % - 35.26 % reduction of aflatoxin in milk compared to the control sample. Reductions in aflatoxin concentrations in milk are not proportional to the applied dose of grams of radiation due to milk coagulation.

AB  - The selective synthesis of 5,6-dihydropyrimidin-4(3H)-one scaffold (precursor of dihydrouracil) was a very difficult synthetic challenge that, so far, has not been achieved. For the first time, in this paper, green, selective and high-yields approach to 40 novel 5,6-dihydropyrimidin-4(3H)-ones (DHPMs) by one-pot reaction of aldehydes, Meldrum's acid and isothioureas under solvent-free conditions, in the presence of water, since an additive is presented. In the majority of cases, introduced methodology gave an unprecedented tautomer-selective fashion toward targeted compounds with excellent tautomeric purity (>99.9%), which reached 100% in few cases. The molecular structure of the five compounds has been determined by X-ray crystallography. In each one of them, very short length for the corresponding N2-C1 bond was noticed, making them especially interesting from a structural standpoint. This experimental fact can imply a highly localized electron π density in this part of each heterocyclic ring. The obtained experimental results, which are determined from NMR and ESI-MS study, indicate that this Biginelli-type reaction smoothly proceeds in a one-pot mode, pointing to the three-step tandem process, proceeding via the Knoevenagel, aza-Michael, and retro-Diels-Alder reactions. The presented strategy also had the following advantages: reduction amount of waste, excellent values of green chemistry metrics (cEF, EcoScale and GCIS), and it is the first eco-friendly strategy toward the DHPMs scaffold. © Copyright 2018 American Chemical Society.
