Hydroxyl radical

Pomegranate fruit Pomegranate (Punica granatum L.) is considered one of the oldest known edible fruit that is mentioned in the Koran, the Bible, the Jewish Torah, and the Babylonian Talmud as “Food of Gods” that is symbolic of plentyness, fertility and prosperity.(45) They are widely cultivated in Iran, India, and the Mediterranean countries such as Turkey, Egypt, Tunisia, Spain, and Morocco.(46,47,48) The pomegranate fruit is berry-like with a leathery rind enclosing many seeds surrounded by…

in) R1=OH, R2=R3=H,R4=OCH3 3i : 7-Hydroxy-3-(2,4-dimethoxybenzyl)chromanone (2’-Methoxydihydrobonducellin) R1=OH,R3=H,R2=R4=OCH3 Antioxidant activity of above synthesized derivatives were studied, on that basis 3-benzylchromones with phenolic hydroxyl group (2h & 2i) showed highest activity than com-pound with methoxyl group (2e & 2g) because double bond between C2-C3 done major im-pact on activity of compound. The result of inhibition concentration (IC50 in µM) for 2h & 2i were 162 µM and…

The kinetics of the reaction between peroxomonosulphate with Lactic acid was studied in the presence of Mn(II) at alkaline pH. The reaction followed first order with respect to peroxomonosulphate. The rate of the reaction was studied under pseudo first order condition and found to increases with the [Mn(II)] and lactic acid. Thermodynamic parameters were calculated and reported. Based on the results a rate equation, kinetic scheme and a most probable mechanism has been predicted. Keywords: Alpha…

Periodontiits: Periodontal disease is one of the most prevalent disease throughout the world (Albandar 2011). It is a chronic bacterial inflammatory infection leading to destruction of supporting tissues of teeth (Moffatt, Whitmore et al. 2011). It is second to dental caries as a cause of tooth loss among adults in developed countries (Gautam, Jindal et al. 2011), affecting 47.2% adults aged 30 years and older in the US (Eke, Dye et al. 2012). Organisms causing periodontal diseases: In a…

Aging Context Aging is treated as a vital factor in the etiology of human disease (ES-2014-aging). It is also an important risk factor for AD and PD onset and progression. Biologically, aging is an inevitable biological process that is characterized by a progressive decline in physiological function, including cognition, and by the increased susceptibility to disease (RX-2013). Oxidative stress and mitochondrial malfunction are two interdependent mechanisms that play a central role in brain…

consist of four critical steps starting from the initial reactants (CH4, NH4+, oxo): C-H activation followed by a hydrogen atom abstraction (HAA) from CH4 to form some combination of the hydrogenated complex, ammonium or ammonia, and a methyl radical; a radical rebound (RR) to form a methanol adduct and ammonium; methanol dissociation from the metal; and catalysis regeneration via oxygen atom transfer. We modeled these steps as stationary points throughout the reaction coordinate, each point…

reinforcements, which makes it an incredible solution for wiping out free-radicals, helping cure sufferings like pigmentation and carcinogenic cells. This property guarantees that camel drain battles oxidative anxiety. The cell reinforcement property of camel drain additionally makes it very viable in controlling and decreasing the side effects of the disease. 21. Hostile to Aging: Camel Milk contains a compound called alpha-hydroxyl corrosive which smoothens almost negligible differences and…

absorbing heat, it will eventually make the Earth warmer, causing a greenhouse effect. Although not a major contender compared to all the other greenhouse gases, its presence still makes a difference. “Carbon monoxide readily reacts with the hydroxyl radical (OH) forming a much stronger, greenhouse gas--carbon dioxide. This, in turn, increases concentrations of methane, another strong greenhouse gas, because the most common way methane is removed from the atmosphere is when it reacts with OH”…

Biotechnology is the exploitation of biological processes for industrial and other purposes, especially the genetic manipulation of micro-organisms for the production of antibiotics, hormones and more or any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use (United Nations, 2012). Will the application of biotechnology in gene therapy be the solution for people that suffer from Chronic…

Americans are constantly bombarded with the guilt of having high cholesterol, without really understanding what cholesterol even is. Cholesterol is actually incredibly important in keeping the body functioning. In fact, studies have shown that too-low cholesterol levels can cause anxiety and depression, among other issues, in both men and women. (1) High cholesterol is potentially very dangerous and can even be life-threatening. Luckily, lowering blood cholesterol levels is not as hard as one…
