(MARCEL DEKKER INC, 1999-01)Organic acids and phosphate were determined in soil aqueous extracts by capillary zone electrophoresis using indirect UV detection. The electrolyte system was 10 mM sodium benzoate with 0.5 mM tetradecyltrimetyl-ammonium ...
-
(MARCEL DEKKER INC, 1999-05)Different chemical forms of cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), lead (Pb), nickel (Ni), and zinc (Zn) were determined in agricultural soils cultivated with lettuce and celery. These soils have been ...
-
(Instituto de Investigaciones Agropecuarias, 1988-04)Dehydrogenase and respiratory activities were studies in six soils, five of volcanic origin and the other alluvial, as a reference. Dehydrogenases activity was measured by the reduction of 2, 3, 5- Tryphenyl Tetrazolium ...
-
(MARCEL DEKKER INC, 1999)Dissolution profiles of theophylline (TP) from three types of sustained-release (SR) matrix tablets (plastic [PL], lipid [LP], and hydrophilic [HP]) in different dissolution media, with and without enzymes, were established ...
-
(SPRINGER-VERLAG, 2001-10)The possibility of a total substitution of ega proteins in yellow cakes by vegetable proteins isolated from white lupine seeds was studied. The effects of several components on hardness, moisture content, volume, and shape ...
-
(WILEY-V C H VERLAG GMBH, 1998-11)Flutamide, 4-nitro-3-trifluoromethyl-isobutylanilide a synthetic antiandrogenic with therapeutic use in prostatic cancer, is electrochemically studied to propose a new electroanalytical alternative for its quantitative ...
-
(AMER CHEMICAL SOC,, 2003-07-02)Two amaranth glutelin preparations, Gt-bo extracted with borate buffer at pH 10 and Gt-na extracted with 0.1 N NaOH, were characterized and compared with the amaranth polymerized 11 S globulin (Gp, globulin-P). Gt-bo and ...
-
(MARCEL DEKKER INC, 2001)Some organic acids of low molecular weight, generated through breakdown of giant wastes or root exudation, increase the solubilization of heavy metals, such as cadmium (Cd) and copper (Cu) through complexation reactions ...
-
(2010)This work focuses the sensory and physical properties of canned farmed coho salmon (Oncorhynchus kisutch); the effect of flake ice and slurry ice as previous slaughter and chilling conditions was studied. Hydrolytic chemical ...
-
(ELSEVIER, 2010)Recent consumer trends towards healthier and low fat products have had a significant impact on the snack industry. The objective of this study was to examine the most important quality parameters of vacuum and atmospheric ...
-
(ELSEVIER, 2010)A new series of heteroaryl nitrones, 1–7, bearing furoxanyl and thiadiazolyl moieties, were evaluated for their free radical-trapping properties. The physicochemical characterization by electron paramagnetic resonance ...
-
(TAYLOR & FRANCIS INC, 2010)A headspace-mass spectrometry with alternative chromatographic separation using a column switching system was developed for the screening and confirmation of BTEX and styrene in comestible oils. According to the position ...
-
(ELSEVIER, 2010)Substantial progress has been made throughout the last decades in the elucidation of the key players and mechanisms responsible for Ca2+ signal generation in both excitable and non-excitable cells. Importantly, these ...
-
(2010-04)Salmonella enterica serovar Enteritidis has emerged as a major health problem worldwide in the last few decades. DNA loci unique to S. Enteritidis can provide markers for detection of this pathogen and may reveal pathogenic ...
-
(2010)The synthesis of a series of substituted arylpiperazines linked to a 2-(pyridin-3-yl)-1H-benzo[d]imidazole scaffold through an alkylic linker is reported. The novel 1-(2-(4-arylpiperazin-1-yl)alkyl)-2-(pyridin-3-yl)-1H-b ...
-
(Springer, 2010)The effect of a previous hydrostatic highpressure (HHP) treatment on hydrolysis, breakdown and aggregation events in chemical constituents of chilled farmed coho salmon (Oncorhynchus kisutch) was studied. Three different ...
-
(2010)Contraction-related stimuli regulate GLUT4 traffic in C2C12- GLUT4myc skeletal muscle cells. Am J Physiol Endocrinol Metab 298: E1058 –E1071, 2010. First published February 16, 2010; doi:10.1152/ajpendo.00773.2009.—Muscle ...
-
(SOC BRASILEIRA QUIMICA, 2009)An apparatus which allows the direct measurement of the antioxidant capacity of volatiles compounds emitted from some herbs and culinary spices is described. The device comprises: a sample chamber, a mixing chamber, a pump ...
-
(2010)Herbal extracts must be evaluated for their efficacy and safety. In vivo acute toxicity studies must consider the different mechanisms by which active compounds may elicit toxicological outcomes. Thus, a methodology to ...
