Research ArticleOpen accessAll words, across the recordDetermination of Diloxanide Furoate and Metronidazole in Binary Mixture Using First Derivative of the Ratio-Spectra and High-Performance Liquid Chromatography-UV MethodsNora H. Al-ShaalanTwo methods are presented for simultaneous determination of diloxanide furoate and metronidazole. The first method depends on first derivative of the ratio-spectra by measurements of the amplitudes at 242.5 and 285.5 nm for diloxanide furoate and 225.5 and 300 nm for metrinidazole. Calibration graphs were established for 2-100 μg mL-1 for diloxanide furoate and 1-50 μg mL-1 for metronidazole. In … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 7,719 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordHigh Level of Nicotianamine Synthase (NAS3) and Natural Resistance Associated Macrophage Protein (NRAMP4) Gene Transcription Induced by Potassium Nitrate in Trembling Aspen (Populus tremuloides)Karolina M. Czajka, Kabwe NkongoloChanges in gene transcription in response to excess metal concentrations have been reported in many organisms, including yeast, microorganisms and plants. Most investigations on the effects of nickel toxicity in plants use commercial salts whose effects have not been analyzed in detail. The main objective of the present study was to determine the effects of different doses of nickel nitrate … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 15 Jul 2018 · 10,885 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDetermination of Pesticide Residues in Banana by Using High Performance Liquid Chromatography and Gas Chromatography-Mass SpectrometryR. Paranthaman, A. Sudha, S. KumaravelProblem statement: The occurrence of endosulfan, carbendazim, chloropyripos in 10 banana samples in southern area of Tamilnadu, India (hill banana, karpuravalli, monthan, nendran, ney poovan, pachanadan, poovan, rasthali, red banana, robusta) was investigated. Approach: In 7 samples, Carbendazim was found at concentrations ranging from 0.002-0.11 mg kg-1. In three samples, carbendazim was not found, whereas endosulfan, chloropyripos was not detected … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 1 · 1 Mar 2012 · 9,548 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEffect of Intrahippocampal γ Aminobutyrate B Receptor on Pain Sensitivity during Estrous CycleMahnaz Taherianfard, Rohollah GhorbaniProblem statement: There is a relationship between sexual hormones and pain sensitivity and also a role for hippocampal GABAB receptor in nociception. Therefore, the aim of the present investigation was to evaluate the effect of intrahippocampal injection of GABAB receptor agonist (baclofen) and GABAB receptor antagonist (CGP35348) on pain sensitivity during the estrous cycle. Approach: Forty eight adult female rats … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 3 · 26 Nov 2011 · 7,345 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAlterations of HDL Subclasses in Different Lipid Levels of Men and WomenYuye Yang, Luchuan Yang, Mingde Fu et al.With the increase of plasma TG level, both in men and women, apoA-I concentrations of preβ1-HDL and HDL3a were significantly higher while HDL2a and HDL2b were significantly lower. Similarly, with the increase of plasma LDL-C level, apoA-Iconcentrations of preβ1-HDL, HDL3c(in men) and HDL3b were significantly higher while apoA-Iconcentrations of HDL2b were significantly lower. And with the decrease of plasma HDL-C, … …American Journal of Immunology, Vol. 1, Issue 2 · 30 Jun 2005 · 9,077 accessesView PDF Cite
