(MUNKSGAARD INT PUBL LTD, 2000-04)Background/Aims: Low blood Se levels have been previously shown in normal pregnancies (third trimester) and significantly lower levels in patients with intrahepatic cholestasis of pregnancy (ICP), in Finland and in Chile, ...
-
(Elsevier, 2010)The present manuscript describes studies of the electron transfer kinetics at gold electrodes modified by electrostatic self-assemblies of polyethylenimine (PEI), DNA and gold nanoparticles (NP) by Scanning Electrochemical ...
-
(Sociedad Chilena de Química, 1998)The potential energy surface of hstamine monocation is calculated by MNDO types methodologies and by the Reaction Field model at CNDO/2 level, in order to rationalize the experimental findings about the relative abundance ...
-
(S. Karger AG, 2008)Many features of aging result from the incapacity of cells to adapt to stress conditions. When damage accumulates irreversibly, mitotic cells from renewable tissues rely on either of two mechanisms to avoid replication. ...
-
(2014)A hydrogen-terminated Si (111) surface was modified to form an aminoterminated monolayer for immobilization of streptavidin. Cleavage of an N-(ω- undecylenyl)-phthalimide covered surface using hidrazine yields an amino ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2004-06)Hybrid nanocomposites based on siloxane sols, chitosan and poly(monomethyl itaconate) (PMMI) as organic polymer counterparts were prepared. Tetraethyl ortosilicate was used as inorganic network fort-ning reagent that was ...
-
(2013)In this work, a new method to quantify nitrofurantoin in aqueous media using a flow injection system connected to commercially available screen-printed carbon nanofibers was developed. A pretreatment of the screen-printed ...
-
(AMER SOC PHOTOBIOLOGY, 2005-03)Thyronine derivatives are essential indicators of thyroid gland diseases in clinical diagnosis and are currently used as standards for developing ordinary biochemical assays. Photooxidation of gland hormones of the thyronine ...

(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 ...
-
(ELSEVIER SCIENCE SA, 2001-12-31)Detection of O-2((1)Delta(g)) phosphorescence emission, lambda(max) = 1270 nm, following laser excitation and steady state methods were employed to determine the total rate constant, k(T), for the reaction between the ...
-
(2013)The effect of a previous hydrostatic high-pressure (HHP) treatment on sensory and physical quality of chilled coho salmon (Oncorhynchus kisutch) was investigated. As a first stage, a 2(2) factorial design based on the ...
-
Separation of Cu(II) and Mo(VI) from mine waters using two microporous membrane extraction systems (Marcel Dekker Inc, 2000)This is a report on the separation and recovery of Cu(II) and Mo(VI) ions from two Chilean mine waters using two hollow fiber-type microporous liquid membrane extraction systems. LIX-860 (a salicylaldoxime) and Alamine 336 ...
-
(2007)This is a report on the separation and recovery of zinc ions from an acidic mine drainage using a stirred transfer cell-type emulsion liquid membrane contactor. Di(2-ethylhexyl) phosphoric acid was used as a highly selective ...
-
(2010)The International Collaboration to Sequence the Atlantic Salmon Genome (ICSASG) will produce a genome sequence that identifies and physically maps all genes in the Atlantic salmon genome and acts as a reference sequence ...
-
(2010)This paper presents a chronological sequence of human occupation from the end of the Pleistocene to the present day in the Atacama Desert, one of the most barren territories of the New World. The occupational sequence ...
-
(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 ...
-
(Wiley, 2014)Serotonin (5-HT) production and expression of 5-HT receptors (5-HTRs) occur early during prenatal development. Recent evidence suggests that, in addition to its classical role as a neurotransmitter, 5-HT regulates neuronal ...
-
(ELSEVIER, 2008-07)Increased serum uric acid has been identified as an independent risk factor for cardiovascular disease. However, because of its antioxidant capacity, uric acid may play a beneficial role in endothelial function. This ...
-
(Public Library Science, 2016)Background Paper mulberry (Broussonetia papyrifera (L.) L'Her. ex Vent) is a dioecious tree native to East Asia and mainland Southeast-Asia, introduced prehistorically to Polynesia as a source of bark fiber by ...
-
(Oxford University Press, 2017-05)With increased life expectancy, women will spend over three decades of life postmenopause. The menopausal transition increases susceptibility to metabolic diseases such as obesity, diabetes, cardiovascular disease, and ...
