Background and purpose: Paraquat (PQ) is a bipyridinium herbicide that is very soluble in water. This non-selective contact herbicide is widely used in agriculture for weed control. In addition to the environmental impact, paraquat affects the entire body, especially the respiratory system, central nervous system and lymph nodes. In this study degradation of paraquat was investigated using Fent...
Background and purpose: Resveratrol (RSV) is a naturally existing polyphenolic compound abundantly found in grapes and several plants. It has potent free radical scavenger and antioxidative properties with significant effects in reducing oxidative damage. Oxidative stress and mitochondrial dysfunction contribute to PQ induced tissue damage. In this study, the protective effect of RSV was invest...
Erratum After publication of the original article [1], it came to the authors’ attention that there was an error in the PQ pharmacokinetics sub-section of the Background section. The following sentence is affected: “There is no PK interaction between PQ and either artesunate-pyronaridine [76] or mefloquine [69, 77]; no PK interaction data exist for PQ and artemetherlumefantrine (AL).” This sent...
Reactions of 9,10-phenanthrenequinone (PQ) in toluene with [M(II)(PPh3)3X2] at 298 K afford green complexes, trans-[M(PQ)(PPh3)2X2] (M = Ru, X = Cl, 1; M = Os, X = Br, 2) in moderate yields. Reaction of anhydrous RhCl3 with PQ and PPh3 in boiling ethanol affords the dark brown paramagnetic complex, cis-[Rh(PQ)(PPh3)2Cl2] (3) in good yields. Diffusion of iodine solution in n-hexane to the trans-...
With widespread non-linear loads and the increasing penetration of distributed generations in power system, harmonic pollution has become a great concern. The causes not only include integer harmonics, but also interharmonics, which exacerbate complexity analysis. In addition, output variability highly renewables such as electric arc furnaces photovoltaic solar or wind generation may lead to we...
A classification of all possible icosahedral viral capsids is proposed. It takes into account the diversity of hexamers’ compositions, leading to definite capsid size. We show how the self-organization of observed capsids during their production results from definite symmetries of constituting hexamers. The division of all icosahedral capsids into four symmetry classes is given. New subclasses ...
I. The function of plastoquinone PQ in photosynthesis has been measured by absorption changes in the UV at 265 nm. These measurements have been refined by the application of the very sensi tive repetitive pulse technique. The reduction and oxidation of plastoquinone in chloroplasts have been measured 1. in short flashes, 2. in long flashes and 3. in double flashes. The results can be described...
This paper presents the application of Hilbert transform and artificial neural network (ANN) for power quality (PQ) disturbance classification. The input features of the ANN are extracted from the envelope of the disturbance signals by applying Hilbert transform (HT). The features obtained from the Hilbert transform are distinct, understandable and immune to noise. These features after normaliz...
<span lang="EN-US">Good power quality delivery has always been in high demand system utilities where different types of disturbances are the main obstacles. As these have distinct characteristics and even unique mitigation techniques, their detection classification should be correct effective. In this study, eight were synthetically generated, by using a mathematical approach. Then, conti...
BACKGROUND The present study was designed to analyze the dynamic changes in transforming growth factor beta 1 (TGF-β1), interleukin (IL)-10, and tumor necrosis factor alpha (TNF-α) in paraquat (PQ)-intoxicated rats and to evaluate the effects of artesunate on PQ-induced lung injury. METHODS Sixty healthy male Sprague-Dawley (SD) rats were randomly assigned to the control (n = 10), PQ (n = 25)...
