For its specific physical and physicochemical properties, the water treated with low-frequency low-pressure glow plasma (GPTW) affects the growth of plants and enhances the phytoavalibility of selenium (Se) ions from the nutrient solution. The basic biometric and physiological parameters of cucumber and the uptake of Se ions applied as selenate (Na2SeO4) from the nutrient solution prepared using GPTW...
Broccoli consumption is rising worldwide and fertilization is a tool to increase its production. However, little is known about the effect of mineral supplementation to the soil on the bioactive compounds. Therefore, the aim of this investigation was to analyze the content of vitamin C, total phenolic compounds and the antioxidant capacity of broccoli florets cultivated under different nitrogen (N)...
Background. Breast cancer is the most common malignant tumour in women in Poland. To reduce the risk of breast cancer, appropriate prevention is necessary. Numerous studies conducted over many years in Poland and throughout the world have demonstrated a significant effect of selenium on prevention of disease, including breast cancer in women. The following paper aims to present the literature on effects...
Background. Persistently high incidence of ‘diseases of affluence’ (including cancer) motivates numerous research teams to look for causes of morbidity, as well as to search for preventive methods and effective therapeutic measures. The paper aims to present the literature on effects of selenium (Se) on prevention of gastrointestinal and lung cancer. Material and methods. Based on national and international...
Background. Selenium is an element of very great importance for the proper functioning of the human body, mainly due to its antioxidant properties. Selenium exhibits a preventive effect in the case of cardiovascular disease, the immune system, male infertility and inhibits the toxic action of other agents. Selenium is important for Hashimoto’s disease. Intake of selenium in the diet slows the aging...
W pracy przedstawiono wyniki oddziaływania oleju napędowego, przepracowanego oleju silnikowego oraz selenu (IV i VI), na aktywność peroksydazową gleby. Doświadczenie przeprowadzono w warunkach laboratoryjnych na piasku gliniastym o zawartości węgla organicznego 8,7 g·kgˉ¹. Do próbek gleby wprowadzono w różnych kombinacjach kwas selenowy (IV) lub kwas selenowy (VI) (ilość dodanego Se wynosiła 0,05...
The pancreatic cancer is a disorder with an exponentially increased incidence, especially over the last few years. Moreover, it is estimated that almost 95% of the patients with this disease are presenting to the hospital in the advanced and unresectable stages. Also, over the past few decades the development and advance of the surgical methods and techniques have improved, with the most of the operatory...
The objective of this study was to investigate the effect of Selenium (Se) supply (0, 3, 6, 12, 24 mg kg−1) on the growth, photosynthetic characteristics, Se accumulation and distribution of flue-cured tobacco (Nicotiana tabacum L.). Results showed that low-dose Se treatments (≤6 mg kg−1) stimulated plant growth but high-dose Se treatments (≥12 mg kg−1) hindered plant growth. Optimal Se dose (6 mg...
The present study reports the levels of mercury and selenium in Sarpa salpa and Balistes capriscus collected along the coast of Mahdia and Sfax (Tunisia). The systems constituted by S. salpa and Robphildollfusium fractum and by B. capriscus and Neoapocreadium chabaudi were tested as potential bioindicators to monitor environmental Hg pollution in marine ecosystems. Mercury and selenium concentrations...
The objective of this study was to investigate the effect of exogenous selenium (Se) supply (0, 2, 4, 8, 16 μM) on the growth, lipid peroxidation and antioxidative enzyme activity of 100 mM NaCl-stressed melon (Cucumis melo L.) seedlings. Salt stress significantly reduced the growth attributes including stem length, stem diameter, dry weight and increased antioxidative enzyme activity [superoxide...
The aim of the research was to find out how foliar selenium (Se) treatment in open field conditions affects plant nutrition, yield and bulb bioactive properties. 10, 50 or 100 μg·mL⁻¹ Se, referred to as Se10, Se50 and Se100 treatments, was applied to onion ‘Hercules’ in 2008 and 2009. Bulb weight, total yield, content of total Se, free selenomethionine and selenomethylselenocysteine, total S, N, P,...
Fungi contain a number of biologically active substances whose importance for human health has been confirmed in several studies. In particular, β-glucans, selenium, vitamin D, C and E should be mentioned. These substances play an important role in shaping the immune system and prevent cancer. β-Glucans reduce the risk of cardiovascular disease and lower the cholesterol level.
