Selenium

student in prevention of selenium – a micronutrient and mineral deficiency in humans. Selenium is linked to probable incidences of certain diseases including male infertility, heart diseases, viral infections and some cancers. Globally, over one billion individuals have selenium deficiency as a result of poor diet and majority of them are from countries like Bangladesh, New Zealand and Australia where levels of selenium in soil are extremely low. Mahmudur Rahman, a PhD student in Bangladesh, along with his supervisors Professor William Erskine and Professor Kadambot Siddique has been successful in developing a method to increase selenium concentration in lentil…

Selenium is a trace mineral, one of the essential minerals found in minute amounts in the body. Our body needs selenium to perform several functions. Selenium works closely with vitamin E in some of its metabolic actions and in the promotion of normal body growth and fertility. It protects the immune system by preventing the formation of free radicals, which can damage the body. Selenium is a natural antioxidant and appears to preserve the elasticity of tissue by delaying oxidation of…

5-CinthiaV-Selenium The name of my element is Selenium. The element symbol is “Se”. Selenium was discovered in Sweden by Jons Jacob Berzelius in 1817. Selenium is an origin for a greek word meaning moon. Selenium has four energy levels. In the first energy level, it has two electrons. The second energy level has eight electrons. The third energy level has 18 electrons. The fourth energy level has six valence electrons. Selenium has forty-five neutrons. Selenium has the…

Meta Description: The chemical Selenium has been known to play a key role in fertility for men. One of the great joys and privileges of being and adult man or woman is having the opportunity to bear and raise children. It is something many people cherish and spend a great deal of their lives preparing for in order to become good parents. Unfortunately, nature and biology sometimes interfere with one's ability to conceive. Dealing With Infertility It is estimated that one in eight or 12.5% of…

Selenium: The Essential Element Introduction Over the years, selenium is known to be the essential element in all forms of life. Selenium is a metalloid belonging to the block p, group 16, period 4. It is a gray metallic rare element widely distributed within Earth’s crust which has an atomic number of 34 and a symbol “Se”. Selenium was discovered in 1817 by Jöns Jacob Berzelius and Johan Gottlieb Gahn after analysing an impurity contaminating the sulphuric acid being produced by a factory…

10 Health & Wellness Benefits of Selenium Selenium is an essential mineral that plays a significant role in health. A balanced plant-based diet should provide enough selenium to keep you well. However, some circumstances deplete the body's selenium levels, including smoking, drinking alcohol, taking oral contraceptives, and having certain health conditions like ulcerative colitis or Crohn's disease. Find out the incredible health and wellness benefits of selenium below. Then, reap the…

Selenium plays an important role in boar nutrition via participating in selenoprotein synthesis. It seems likely that selenoproteins are central for antioxidant system regulation in the body. Se-dependent enzyme glutathione peroxidase (GSH-Px) is the most studied selenoprotein in swine production. However, roles of other selenoproteins in boar semen production and maintenance of semen quality also need to be studied. Boar semen is characterised by a high proportion of easily oxidized long chain…

This is not happen in our study due to using selenium and vitamin E. This because selenium and vitamin E inhibit protein kinase and AKT, which leads to decrease the expression of NF-ĸB and VEGF, So they can decrease gemcitabine resistance and increase its apoptotic effect and also, inhibit metastasis post-RFA (Li et al., 1998; Curley et al., 1999; Gopalakrishna & Gundimeda, 2002; Vivanco & Sawyers, 2002; Yang et al., 2005; Meng et al., 2007) . HCC patients treated with RFA plus selenium and…

(2013) conducted investigations of copper and selenium recovery from copper anode slimes. The process consisted of two hydrometallurgical steps; decopperization in sulphuric acid media and dissolution of selenium in caustic solution. Temperature caustic concentration, oxygen partial pressure and reaction time were all found to increase selenium dissolution. The caustic concentration was varied between 0.36 and 5 mol/L. Maximum selenium extraction was obtained with 4 mol/L caustic concentration.…

In The Disappearing Spoon, Sam Kean explains chemistry broadly yet detailed through interesting and thrilling stories. He talks about the elements on the periodic table and how the table came into existence and why it is arranged the way it is. He also looks deeply into the history and concepts of some interesting elements. In chapter 15 called “An Element of Madness,” he goes into an explanation about selenium, manganese, palladium, barium, and unununium. Pathological science is considered…
