-
(2006)The reaction of singlet molecular oxygen with a series of cyclic and acyclic α-diimines was studied. Time-resolved methods were used to measure total reaction rate constants and steady-state methods were used to determine ...
-
(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 ...
-
(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, ...
-
(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 ...
-
(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 ...
-
(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)Thyronine derivatives are essential indicators of thyroid gland diseases in clinical diagnosis and are currently used as standards for developing ordinary biochemical assays. Photo-oxidation of gland hormones of the thyronine ...
-
(1969)The shift of the first and second spin allowed bands due to the stepwise replacement of the nitrogen atoms in a complex of Cr(III) of the CrN6 type by oxygen atoms of water or of carboxylic groups is analyzed in terms of ...
-
(1993)The relations between the atomic softness and the atomic electric dipole polarizability are studied, both in a theoretical and an empirical way. For atoms and ions with one or two valence electrons a remarkably good ...
