(1989)The exchange between bromide and chloride counterions at the surfaces of dioctadecyldimethylammonium vesicles has been examined through fluorescence quenching experiments. The quenching of the fluorescence of vesicle-incorporated ...
-
(1997)The kinetics of the reaction between N-p-methoxybenzyliden-cc-phenylglycine methyl ester and nitrosobenzene, using benzene as the solvent and both acetic and chloroacetic acid as catalysts, was studied by means of UV-VIS ...
-
(2006)A standard aqueous extract of Mangifera indica L., used in Cuba as antioxidant under the brand name VIMANG®, was tested in vivo for its anti-inflammatory activity, using commonly accepted assays. The standard extract of ...
-
(2006)The effect of the addition of rosa mosqueta husk extract (RME) on thermal oxidation of nontreated (HZO) and treated (THZO) Chilean hazelnut seed oil was evaluated at 180°C for 18 h. THZO to which was added 339 mg/kg of ...
-
(1997)Citrus limon seedlings respond to fungat attack inducing the phenylpropanoid pathway producing phytoalexins. The de nero synthesis of one of the main enzymes, phenylalanine ammonia-lyase (PAL), is accomplished after 24 ...
-
(2004)A standard aqueous extract of Mangifera indica L., used in Cuba as an antioxidant under the brand name of VIMANG®, was tested in vivo for its anti-inflammatory activity using commonly accepted assays. M. indica extract, ...
-
(2006)The synthesis of a series of new benzimidazo[1,2-c]quinazolines starting from 2-nitrobenzaldehyde and o-phenylendiamine is described. The structure elucidation of the products is based on detailed NMR analysis of experiments ...
-
(1967)Dimensional analysis and the theory of biological similarities were applied to the mammalian respiratory system. Through dimensional and solution matrices a set of 9 Pi-numbers of Buckingham was obtained. Products of ...
-
(2004)The high temperature antioxidant efficiency of α-tocopherol, α-tocotrienol and a mixture of both on hazelnut oil were evaluated. Crude hazelnut oil (HZO), crude hazelnut oil treated with alumina (THZO), as well as three ...
-
(1993)The concentration of the triterpene oleanolic acid in leaves of Baccharis linearis varies at different stages of plant growth from 1.9 to 3.0 g kg-1 fr. wt. Larvae of Heliothis zea, starved with 1.4 mg of oleanolic acid ...
-
(2005)The new oxoisoaporphines 7H-dibenzo[de,h]quinolin-7-one, 5-methoxy-7H-dibenzo[de,h]quinolin-7-one, 5-methoxy-6-hydroxy-7H-dibenzo[de,h] quinolin-7-one, 5-hydroxy-7H-dibenzo[de,h]quinolin-7-one and 5-methoxy-6H-dibenzo[de ...
-
(2005)Changes in pH, total volatile basic nitrogen (TVB-N) and K-value were determined in golden kingclip species (Genypterus blacodes) frozen and stored at -18°C and -30°C for 6 months and golden kingclip canned fish in two ...
-
(2005)Detection of O2(1Δg) emission, λmax = 1270 nm, following laser excitation and steady-state methods were employed to measure the total reaction rate constant, kT, and the reactive reaction rate constant, kR, for the reaction ...
-
(2005)Hydrolytic and oxidative rancidity development and its effect on quality loss were studied in frozen mackerel (Scomber scombrus) by biochemical and sensory indices. The effect of the lipid content on fish damage at a ...
-
(Swets en Zeitlinger B.V., 1996)The antipyretic and antiinflammatory properties of a new sesquiterpene, spartidienedione, isolated from Psila spartioides (Asteraceae) were evaluated in rabbits and guinea pigs. At the dose of 25 mg/kg, this substance ...
-
(2005)Pretreatment of pinus Radiata logs with the white-rot fungi Ceriporiopsis sp (9C), Pleurotus sp (9P), and Phlebia sp (24P), under field conditions was studied. The lignin content was evaluated by gravimetric techniques ...
-
(2004)Complexes of the type Delta- and Lambda-[Co(diimine)(2)carbohydrate](2+) were synthesized with the diimines: 1,10-phenanthroline and 2,2'-bipyridine and with the carbohydrates: aminosugars, hexoses, pentoses and sucrose, ...
-
(1986)The photochemistry of alkyl pyruvates of the type CH3COCOOCHR2 has been examined in solution using a combination of product studies and laser flash photolysis techniques. The results indicate that the main reaction path ...
