(Royal Society of Chemistry, 2009)A new extended metal-organic framework [Cu(H(2)btec)(bipy)](infinity) (1) (H(4)btec=1,2,4,5-benzenetetracarboxylic acid; bipy= 2,2'-bipyridine) has been hydrothermally synthesized. Violet crystals are formed in a monoclinic ...
-
(2009)A commercial diet including synthetic antioxidants (BHT-ethoxyquin mixture) (diet I) was provided to coho salmon (Oncorhynchus kisutch) in parallel with two diets including natural antioxidants (tocopherol isomers rich ...
-
(2009)Eight new platinum(II) complexes with 3-(5-nitrofuryl)acroleine thiosemicarbazones showing anti-trypanosomal activity were synthesized, characterized and in vitro evaluated. Most of the complexes showed IC50 values in the ...
-
Ni/Ni oxides nanoparticles with potential biomedical applications obtained by displacement of a ... (2008)A new synthesis and stabilization method was developed for paramagnetic nanoparticles composed of nickel and nickel oxides. Nickel/nickel oxides nanoparticles were synthesized by a method based on ligand displacement of ...
-
(2009)Computed bond lengths and angles of methyl ethyl and dimethyl triphenyl phosphonium ylidic diesters, 1b, c, respectively, are similar to those in the crystal, as for the diethyl ester, 1a, where both acyl oxygens are anti ...
-
(2009)In rat ovary chronic cold stress increases sympathetic nerve activity, modifies follicular development, and initiates a polycystic condition. To see whether there is a relationship between the previously described changes ...
-
(2008)The characteristics of the seeds from Chilean palm and the detailed composition of its fat are studied starting from 4 lots of seeds from the two regions being the major producers of Chilean palm seeds. From the proximate ...
-
(2009)Bioactive compounds of pulp (CP) and ethanolic (CE) extracts of the cactus pear (Opuntia ficus-indica) were encapsulated with maltodextrin (MD) or inulin (I). A 22 statistical factorial design was then used to study the ...
-
(2009)The reaction of (2,6-diisopropyl-phenyl)-acetimidoyl chloride or (2,6-dimethyl-phenyl)-acetimidoyl chloride with 2,6-dimethylaniline in the presence of triethylamine yields a mixture of isomers N′-(2,6-diisopropyl-phenyl ...
-
(2008)Novel liquid crystalline materials based on chiral calamitic 1,2,4- and 1,3,4-oxadiazole derivatives were synthesized and their thermotropic mesomorphism investigated by polarizing optical microscopy and differential ...
-
(2006)NFκB is a participant in the process whereby cells adapt to stress. We have evaluated the activation of NFκB pathway by hyperosmotic stress in cultured cardiomyocytes and its role in the activation of caspase and cell ...
-
(1983)2-Hydroxy-3-(p-hydroxyphenyl)-6-methylpyrazine (HHMP) is identified as the product obtained by acidic degradation of amoxycillin in the presence of formaldehyde. I.R., n.m.r. and elemental analysis data are reported. The ...
-
(2008)A novel series of 2-benzothiophenealkylpiperazine derivatives 11 (a-d) with potential affinity at 5-HT1A serotonin receptors have been synthesized via solvent-free, microwave-promoted Michael addition of benzo[b]thiophene ...
-
(2008)The Rh-catalysed hydroformylation of isopropylidenecyclohexane derivatives obtained by intramolecular diene cyclisations affords the corresponding aldehydes in good yields and in a completely chemo- and regioselective ...
-
(1999)St I is a toxin present in the Caribbean Sea anemone Stichodactyla helianthus which is highly hemolytic in the nanomolar concentration range. Exposure of the toxin to free radicals produced in the pyrolysis of 2,2′ ...
-
(2006)Transmissible Spongiform Encephalopathies are fatal and infectious neurodegenerative diseases characterized by extensive neuronal apoptosis and the accumulation of an abnormally folded form of the cellular prion protein ...
-
(2009)An oxygen radical absorbance capacity (ORAC) method based on pyrogallol red bleaching (ORAC-PGR) was used to evaluate the scavenging activity of berry extracts (blackberry, blueberry, and raspberry). Among berry extracts, ...
-
(1988)The enthalpies of the reaction between glutathione and amoxycillin have been measured directly using a flow microcalorimeter. Comparative results are obtained by using an ac polarographic method previously developed in our ...
-
(2008)Properties of inclusion complexes between morin (M) and β-cyclodextrin (βCD), 2-hydroxypropyl-β-cyclodextrin (HPβCD) and Heptakis (2,6-O-di methyl) β-cyclodextrin (DMβCD) such as aqueous solubility and the association ...
-
(2006)Free radicals may be reaction intermediates in biological systems in more situations than are presently recognized. However, progress in detecting such species by Electron Spin Resonance (ESR) has been relatively slow. ESR ...
