USE OF SEA BUCKTHORN FRUITS IN THE PASTRY MANUFACTURING

Different researches on optimizing the shelf life of pastries (gingerbread, sponge cakes) that are produced by adding sea buckthorn flour (2 - 4 % by weight of the flour used) are presented in this study. This study shows the impact of biologically active substances on structural and mechanical, physicochemical, microbiological properties as well as the antioxidant activity of products under the conditions of in vitro gastric digestion. It has been demonstrated that the sea buckthorn flour increases the porosity of pastries, reduces the wet gluten amount and this contributes to moisture loss. The organoleptic assessment indicates that the addition of 2 % sea buckthorn flour improves the appearance, the color and the consistency of pastries. Microbiological analysis showed that samples with added sea buckthorn flour exhibit microbiological stability due to the sea buckthorn chemical composition. The antiradical activity DPPH• in conditions of in vitro gastric digestion of the samples with added sea buckthorn flour increases in a positive way, indicating a clearly positive effect on health

INFLUENCE OF IODINATED OIL AND MARGARINE ON THE THYROID SYSTEM OF RATS

Iodine deficiency is the most prevalent micronutrient deficiency in the world today. Food fortification is an important compliment to food-based approaches, and iodine fortification of foods as one of the strategies for the control of iodine deficiency. Manufacturing and consumption of sunflower oil fortified with iodine as well as derivative products on it basis is a perspective direction for elimination of alimentary dependent iodine deficiency disorders. The present work examines morphological changes in the thyroid system of rats at the experimental mercatholile-induced hypothyroidism. As well it determines the influence of iodinated oil and margarine on the thyroid system of rats. It specifies the safe value of iodinated oil and margarine for rats. In-vivo study demonstrated the efficacy of fortification of lipid products with iodine under iodine deficiency status

MONOAMINE OXIDASE INHIBITION IMPROVES VASCULAR FUNCTION IN MAMMARY ARTERIES FROM NON-DIABETIC AND DIABETIC PATIENTS WITH CORONARY HEART DISEASE

Monoamine oxidases (MAOs) are mitochondrial enzymes with 2 isoforms that have emerged as important contributors to cardiovascular oxidative stress via the constant generation of hydrogen peroxide. The present study was purported to assess whether MAO-derived H2O2 contributes to the endothelial dysfunction in mammary arteries harvested from coronary heart disease patients with/without diabetes mellitus subjected to coronary artery bypass grafting. To this aim the effects of MAO inhibition on vascular contractility to phenylephrine and endothelial-dependent relaxation (EDR) in response to acetylcholine were studied in vascular segments. Clorgyline (irreversible MAO A inhibitor), selegiline (irreversible MAO B inhibitor), and moclobemide (reversible MAO A inhibitor) were applied in the organ bath (10Âľmol/L). MAO expression was assessed by immunohistochemistry. We found a constant impairment of EDR that has been significantly attenuated in the presence of the MAO A and B inhibitors in both groups of coronary heart disease patients. MAO B was the dominant isoform in all human diseased vessels. In conclusion, in vitro inhibition of MAO significantly improved endothelium-dependent relaxation in human mammary arteries, regardless the presence of diabetes. These data suggest that MAO inhibitors might be useful in restoring endothelial response in clinical conditions associated with increased oxidative stress, such as coronary artery disease and diabetes.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
