Selenium (Se) is an essential micronutrient in both human and animal nutrition that exists in a wide array of different forms, both organic and inorganic. Selenoamino acids (SeAAs), such as selenocystine (SeCys2), selenomethionine (SeMet), and methylselenocysteine (MSC) are organic species with reported health benefits of cancer prevention, increased fertility and improved immunological status. However, supplementation of SeAAs can be challenging, due to their reported narrow therapeutic range of indices, low bioavailability and increased susceptibility to oxidation. To address this, SeAAs were encapsulated into nanoparticles (NPs) to lower their toxicity profiles in comparison to their native form, in addition to offering …

The increase in antibiotic resistance has become a global challenge to public health. In this study, an atmospheric cold plasma (ACP) system was applied for combating methicillin-resistant Staphylococcus aureus (MRSA) and its methicillin resistance gene (mecA) during food wastewater treatment. The plate count and flow cytometry methods were employed to estimate the damage in MRSA induced by plasma treatment. A quantitative real-time PCR (qPCR) method was used to assess the plasma-induced degradation of the mecA genes. The inactivation of MRSA and degradation of extracellular (e-) and intracellular (i-)mecA genes were investigated in phosphate buffered solution as a function of plasma …
