-
(1985)Adsorption isotherms of 1-heptene and n-heptane were determined at three near-ambient temperatures on a nonporous silica (Aerosil 200 They appear to lend support to the hypothesis that the double bond of the olefins ...
-
(Society of Biology of Chile, 2004)The expression, at the mRNA level, of carotenoid biosynthetic genes from Xanthophyllomyces dendrorhous was studied by RT-PCR. The experimental conditions for the RT-PCR assay were standardized to quantify the relative ...
-
(Royal Society of Chemistry, 2019)Phosphofructokinases (Pfks) catalyze the ATP-dependent phosphorylation of fructose-6-phosphate (F6P) and they are regulated in a wide variety of organisms. Although numerous aspects of the kinetics and regulation have been ...
-
(Wiley, 2021)Discovering the influences between paintings and artists is very important for automatic art analysis. Lately, this problem has gained more importance since research studies are looking into explanations about the origin ...
-
(ELSEVIER, 2006-03)In teleosts, the lateral line system is composed of neuromasts containing hair cells that are analogous to those present in the inner ear of all vertebrates. In the zebrafish embryo and early larva, this system is composed ...
-
(Elsevier, 2016)Effects of pesticides on non-target organisms have been studied in several taxa at different levels of biological organization, from enzymatic to behavioral responses. Although the physiological responses may be associated ...
-
(SOC BIOLGIA CHILE, 2011)Copper is an essential ion that forms part of the active sites of many proteins. At the same time, an excess of this metal produces free radicals that are toxic for cells and organisms. Fish have been used extensively to ...
-
(Elsevier, 2015)A series of zinc phthalocyanine dyes with different electron-donating and electron-withdrawing substituents and using the COOH as the anchor group that interacts with the semiconductor (TiO2) surface, were studied employing ...
-
(AMER CHEMICAL SOC, 2012-02)Myelination is a highly regulated developmental process whereby oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system ensheathe axons with a multilayered concentric membrane. ...
-
(1994)Microsomal preparations from maize seedlings exhibited N-hydroxylase activity with 2-hydroxy-1,4-benzoxazin-3-one (HBOA) as substrate, but not with its 7-methoxy analogue (HMBOA), or their corresponding 2-O-β-d-glucosides. ...
-
(Springer, 2017)Photobiont availability is one of the main factors determining the success of the lichenization process. Although multiple sources of photobionts have been proposed, there is no substantial evidence confirming that the ...
-
(1994)The calculation of the surface-induced enhancement of the binding energy of hydrogen impurities in transition metals, previously reported for close-packed surfaces, are extended to open surfaces in the fcc and bcc structures. ...
-
(2008)Despite a large amount of climatic and oceanographic information dealing with the recurring climate phenomenon El Nin˜o (EN) and its well known impact on diversity of marine benthic communities, most published data are ...
-
(Springer, 2004)Vast areas of southern Chile are now covered by second-growth forests because of fire and logging. To study successional patterns after moderate-intensity, anthropogenic fire disturbance, we assessed differences in soil ...
-
(ELSEVIER SCIENCE BV, 2006-01-25)Indoline-2-thione (BC) and benzimidazole-2-thione (BN) are two aromatic compounds containing a NCS synthonic unit in a heterocyclic ring of five centres, where the main electronic absorption bands are localized in the ...
-
(1984)The novel complexes M(CO)5S(NR2)2 (M = Cr, Mo or W) have been prepared by the addition of N,N′-thiobisamine (NR2 = dimethylamine, piperidine, morpholine or dibenzylamine) to UV-irradiated tetrahydrofuran solutions of M(CO)6. ...
-
(Elsevier Ltd, 1997)Oxidative addition of thiols RSH, R = CH3, CH2CH2CH3, CH2C6H5, C(CH3)3 and C6H4Br, by the complex [CpFe(dppe)1] afforded the oxidized thiolate complexes [CpFe(dppe)-SR]PF6. The reaction of [CpFe(dppe)1] with HSC6H4NH2 ...
-
(1987)The sulphatide content of vesicular membrane fraction from rabbit mucosal gastric microsomes was analyzed. This vesicular membrane fraction, in addition to a high sulphatide content, was enriched in an ouabain-insensitive ...
-
(1990)The reactions of N,N′-thiobismorpholine, {A figure is presented}, with Fe(CO)5, Fe2(CO)9, Fe3(CO)11 and [(η5-C5H5)Fe(CO)2THF]BF4 were examined. Thiobismorpholine undergoes desulphurization towards Fe(CO)5 with formation ...
