However, it must be recognized that the use of the phrase “environmentally related” should be construed in its broadest meaning, that is, everything that is not genetic. Thus, environmental causes by this definition include such things as diet, smoking and drinking habits, and other lifestyle...
(BDEs 153 and 183) did not induce mortality at any concentration tested, meaning that the LC50values were at least greater than 11.7 and 8.4mg/L, respectively. This trend supported the long-held hypothesis that lower-brominated congeners elicit a greater toxic effect[145]. Exposure of zebrafish...
In addition, it is one of the densest, exceeded only by platinum, iridium, and osmium. Rhenium has a hcp crystal structure, with lattice parameters a=276.1 pm and c=445.6 pm. Discovery Rhenium (Latin: Rhenus meaning: “Rhine,”one of the major rivers in Europe) was the second last-...
The name ‘Chrysene’ originates from the Greek word chrysos, meaning ‘gold,’ and is due to the golden yellow color of the slightly impure crystals. However, in pure state, chrysene is a colorless, crystalline solid. It has characteristic red–blue fluorescence under UV light. Some ...
In a different section was another sentence that should have made an abiding impression. It concerned isomers, spontaneously twinned molecules identical in atomic composition but not identical in atomic conformation — or, often, in toxicity. Many chemicals were “chiral”, meaning “handed”. They ...
CBD is bi-phasic, meaning it produces unique effects for any individual user whenever the amount of CBD consumed is substantially elevated or reduced. When CBD is taken in small doses, users typically experience an energizing effect. However, when CBD is taken in high doses, the effects are...
The meaning of the term "low dose" is discussed in relation to endocrine toxicity data for chemicals. Consideration is also given to experimental conditions likely to impinge on the interpretation and extrapolation of such low-dose effects, and the importance of gathering appropriate control data is...
As part of the most used herbicides, glyphosate is the most successful ingredient of agrochemical companies. The main objective of this study was to demons
The redox couple APS-sulfite has E0 60 mV, meaning that APS can reduce to sulfite (by APS reductase –AprAB) and ferredoxin (NADH) (two electron input is required). During APS reduction, AMP (adenosine monophosphate) is formed and then two ADP molecules (by ATP dependent adenylate kinase)...
(5) The definition of similarity is in most of these cases associated with a continuous value, so thresholds are used, typically with arbitrary values. (6) Some useful similar substances may get “lost” during the process meaning one may get wrong results because relevant information is lost....
