-
(Elsevier B.V., 1996)Loratadine, a potent antihistamine drug, is not directly electroreducible at a dropping mercury electrode; however, by means of a nitration procedure it is possible to obtain a nitro-loratadine derivative which has been ...
-
(Royal Society of Chemistry, 1987)In pyridine - formic acid buffer and tetramethylammonium chloride solution over the pH range 0-8.5, nitrofurazone, furazolidone and other nitrofuran derivatives are reduced in a six-electron process, giving rise to a well ...
-
(WILEY-V C H VERLAG GMBH, 2001-07)Megazol (2-amino-5-(1-methyl-5-nitro-2-imidazolyl)-1,3,4-thiadiazol, CAS 19622-55-0), a highly active compound used against several of Trypanosoma cruzi, the causative agent of Chagas disease, is electrochemically studied ...
-
(AMER PHARMACEUTICAL ASSN, 1990)Nifurtimox is polarographically reducible over the whole pH range, the nitro group being reduced to the hydroxylamine group in a 4ē process and subsequently the amine being formed in a 2ē process at a pH value below 4. The ...
-
(1992)Nimodipine, a calcium antagonist belonging to the dihydropyridine family, produces a well‐defined polarographic peak due to the four‐electron reduction of the nitro group. This peak was used to track the photodecomposition ...
-
(1990)The exposure of drugs to light produces photodecomposition processes in several cases: the drugs undergo important chemical changes with a parallel change in their activities or potencies and generally with a loss of their ...
-
(Sociedad Chilena de Cardilología y Cirugía Cardiovascular, 2005)Los polimorfismos de los receptores β Adrenérgicos (AR) influencian el grado de actividad del receptor. Los βAR tienen un rol importante en la regulación de la contractilidad y podrían tener implicancias en el riesgo de ...
-
(2006)The synthesis, characterization and electrochemistry of a novel nanocomposite based on the co-intercalation of lithium and poly(acrylonitrile) (PAN) in molybdenum disulfide [Li0.6MoS2(PAN) 1.2·0.5H2O] is described. The ...
-
(Taylor and Francis Inc., 1998)Interpolymer complex (IC) formation between poly(ethylene-co-maleic acid) and poly(4-vinylpiridine) (P4VPy) has been observed and characterized. Data from viscosity, infrared spectroscopy and thermogravimetric analysis ...
-
(0887-624X, 2005-10-15)The free-radical copolymerization of N-phenylmaleimide (N-PhMI) with acrylic acid was studied in the range of 25-75 mol % in the feed. The interactions of these copolymers with Cu(H) and Co(H) ions were investigated as a ...
-
(MDPI, 2020)Dermatophyte fungal infections are difficult to treat because they need long-term treatments. 4-Nerolidylcatechol (4-NC) is a compound found in Piper umbellatum that has been reported to demonstrate significant antifungal ...
-
(ELSEVIER, 2010)Assessment of the mobility of polychlorinated biphenyls (PCBs) in soils, amended with biosolids at a rate of 30 Mg ha 1, was performed using an incubation process and leaching columns. The incubation process was carried ...
-
(ELSEVIER SCIENCE INC, 2005-06)Atmospheric concentrations of polycyclic aromatic hydrocarbons (PAHs) in Santiago de Chile city were evaluated to study particulate PAHs profiles during cold and spring weather periods. Urban atmospheric particulate matter ...
-
(Public Library Science, 2021)Cardiac hypertrophy is the result of responses to various physiological or pathological stimuli. Recently, we showed that polycystin-1 participates in cardiomyocyte hypertrophy elicited by pressure overload and mechanical ...
-
(Wiley, 2021)Polycystin-1 (PC1) is a transmembrane protein found in different cell types, including cardiomyocytes. Alterations in PC1 expression have been linked to mitochondrial damage in renal tubule cells and in patients with ...
-
(Springer, 2020)A mixture of a nanostructured Rh/RhO(2)phase was easily obtained by thermally treating the macromolecular Chitosan center dot(RhCl3)(x)precursor, while the Rh/Rh(2)O(3)phase was obtained by pyrolyzing PSP-4-PVP center ...
-
(2012)The pyrolysis of several physical mixtures of AuCl(PPh 3) with polymeric [NP(O 2C 12H 8)] n or cyclic N 3P 3(O 2C 12H 8) 3 phosphazenes, formed as solid powders or films with different molar ratios, have been studied under ...
-
(MDPI, 2018-04)Despite the promising biological and antioxidant properties of curcumin, its medical applications are limited due to poor solubility in water and low bioavailability. Polymeric nanoparticles (NPs) adapted to oral delivery ...
-
Polymorphism in gene coding for ACE determines different development of myocardial fibrosis in rats (AMER PHYSIOLOGICAL SOC, 2004-02-01)In humans, the effect of angiotensin-converting enzyme (ACE) gene polymorphisms in cardiovascular disease is still controversial. In the rat, a microsatellite marker in the ACE gene allows differentiation of the ACE gene ...
