AB  - The inconsistency of phytogenic feed additives' (PFA) effects on the livestock industry poses a risk for their use as a replacement for antibiotic growth promoters. The livestock market is being encouraged to use natural growth promotors, but information is limited about the PFA mode of action. The aim of this paper is to present the complexity of compounds present in essential oils (EOs) and factors that influence biological effects of PFA. In this paper, we highlight various controls and optimization parameters that influence the processes for the standardization of these products. The chemical composition of EOs depends on plant genetics, growth conditions, development stage at harvest, and processes of extracting active compounds. Their biological effects are further influenced by the interaction of phytochemicals and their bioavailability in the gastrointestinal tract of animals. PFA effects on animal health and production are also complex due to various EO antibiotic, antioxidant, anti-quorum sensing, anti-inflammatory, and digestive fluids stimulating activities. Research must focus on reliable methods to identify and control the quality and effects of EOs. In this study, we focused on available microencapsulation techniques of EOs to increase the bioavailability of active compounds, as well as their application in the animal feed additive industry.

AB  - Micromorphological and anatomical analyses of the indumentum of Nepeta rtanjensis, a Serbian/local endemic species, were performed by means of light and electron microscopy and described in detail. The leaves and stems bear numerous glandular trichomes, both peltate and capitate, as well as non-glandular unbranched trichomes. A basal epidermal cell, a short stalk cell and a large round head of four secretory cells constitute one peltate trichome. Capitate trichomes are short and long-stalked and can be divided into two types, based on the number of glandular head cells, and further into a few subtypes according to the length and number of cells in stalk. Capitate trichomes of smaller length with one-cellular or with a bicellular head have been previously reported in different Nepeta species; however, according to our best knowledge, no existing study has reported the presence of long capitate trichomes on vegetative organs in any other species of this genus.

AB  - The success of antioxidant therapy in hyperthyroidism implies that disease is mediated by oxidative stress, which is known as one of the causing agents of agemg, degenerative diseases, and cancer. The main objective of our study was to determine possible protective effects of methanolic extract of N. rtanjensis in triiodothyronine (T-3)-induced DNA breaks of human lymphocytes under in vitro conditions, based upon plant antioxidant capacity related to its phytochemical profile, mainly its polyphenolic complex. The total phenolic and flavonoid content and the antioxidant activity using in vitro 1,1-dyphenyl-2-picrylhydrazyl reagent (DPPH) was determined in methanolic extracts of plant leaves and flowers. The phenolic compound content of 62.73 +/- 1.80 mg of GaA/g, exhibited solid antioxidant activity (IC50= 112.59 +/- 0.95 g/ml). The antigenotoxic activity of 0.2, 0.5 and 1.0 mg/ml N. rtanjensis methanol extracts mixture with 100 mu M of T-3 was studied in human lymphocytes in vitro using the Comet assay. It is supposed that the antigenotoxicity of N. rtanjensis methanol extracts was caused by high presence of chlorogenic acid, rosmarinic acid and rutin, all known as efficient antioxidant bioactive compounds, which were determined by ultrahigh-pressure liquid chromatograph with MS/MS Mass Spectroscopy (UHPLC/-HESI-MS/MS).

AB  - There is increasing evidence that substances which are normally present in human or animal bodies may, under the certain circumstances, exhibit deleterious effects on genetic material, therefore acting as endogenous mutagenic agents. Since hormones represent one of the best studied endogenous mutagens, some research focused on the possible role of thyroid hormone in mutagenesis and carcinogenesis. Indeed, thyroid hormones accelerate aerobic metabolism and production of reactive oxygen species (ROS) and, therefore, may exhibit mutagenic effects in various test systems on mammalian cells. However, possible mutagenic effects on prokaryotic DNA has not been investigated so far. Hence, the aim of this research was to compare the sensitivity of TA 100 Salmonella typhimurium with and without metabolic activation with S9 fraction, and human lymphocytes to possible genotoxic effects of triiodothyronine (T-3). Therefore, we used the reverse mutation assay on S. typhimurium (Ames test) and in vitro Comet assay in isolated peripheral blood human lymphocytes. In both tests-systems a broad spectrum of T-3 concentrations was applied. The obtained results showed absence of genotoxic effects of T-3 in bacterial reverse mutation assay and very profound genotoxic effects in human lymphocytes at concentrations higher than 15 mu M. We only observed cytotoxic effects in bacterial system at very high T-3 concentrations (300 and 500 mu M). In conclusion, T-3 was unable to increase the level of reverse mutations in Ames test both with and without S9 mix. Therefore, it seems that ROS production in mitochondria may be the primary cause of DNA damage caused by T-3 in mammalian cells.
