A selective and simple spectrophotometric method has been developed for the determination of phenylpropanolamine HCl (PPA) in its dosage forms. The method was based on the formation of a colored N-vinyl chlorobenzoquinone derivative of PPA through its reaction with 2,3,5,6-tetrachloro-1,4-benzoquinone in presence of acetaldehyde. The colored product exhibits maximum absorbance at 650 nm. Differ...
Ascorbate reduces the oxidation rate of catecholamines and, by an independent mechanism, enhances rabbit aortic ring contractions initiated by catecholamines. The largest significantly different fractional increases in force produced by ascorbate enhancement of norepinephrine (NE), epinephrine, phenylpropanolamine (PPA), and ephedrine (Eph) are 5.5, 1.8, 1.6, and 1.3 times, respectively. In phy...
Background. Phentermine is an internationally recognised amphetamine derivative with significant appetite-suppressing properties. The drug indicated for the short-term management of obesity, as long-term (LT) use phentermine may potentially be associated severe cardiovascular side-effects, abuse and dependence. LT hereinafter describes periods exceeding 12 consecutive weeks. This also potential...
BACKGROUND Prenatal methamphetamine (MAMP) exposure is poorly reflected in neonatal meconium. Often, maternal self-reported MAMP use is not corroborated by positive results in amphetamines immunoassays of meconium, and even if initial test results are positive, they frequently are not confirmed for MAMP or amphetamine (AMP) by chromatographic analysis. The presence of the MAMP metabolites p-hyd...
BACKGROUND Postsurgical peritoneal adhesions (PPAs) are pathologic fibrous bands within the peritoneal cavity. The aim of this study was to investigate the protective effect of hydrogen-rich saline (HRS) on PPAs formation in mice. MATERIAL AND METHODS Adhesions were induced in mice using the cecum rubbing model. The mice were allocated into 4 groups: control sham group without cecum rubbing; PPA...
The title compound, {[Co(C(14)H(16)N(5)O(3))(2)]·2H(2)O}(n) or [Co(ppa)(2)]·2H(2)O}(n), where ppa denotes the 8-ethyl-5-oxo-2-(piperazin-1-yl)-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carb-ox-yl-ate anion, was synthesized under hydro-thermal conditions. The Co(II) atom (site symmetry ) exhibits a distorted trans-CoN(2)O(4) octa-hedral geometry defined by two monodentate N-bonded and two bidentate ...
Quantifying implicit information leakage is important, especially for fully probabilistic systems (FPS). Although many quantitative methods have been proposed (including methods based on mutual information, on α-mutual information, on relative entropy and on pure probability, etc.), there has been little work analyzing their consistency and accuracy. In order to perform this analysis, these met...
