-
(Royal Soc Chemistry, 2015)A small fraction of an acrylate liquid crystalline monomer (<= 5%) is mixed into nematic and smectic liquid crystalline phases, and polymerised through the application of a voltage (electropolymerisation). Polarising ...
-
(JOHN WILEY & SONS LTD, 2004-11)Toxic effects of several nitro-aryl drugs are attributed to the nitro-reduction that may be suffered in vivo, a reaction that may be catalysed by different reductases. One of these enzymes is NADPH-cytochrome P450 reductase, ...
-
(Sociedad Chilena de Quimica, 2012)4,4-Dimethyl-5,8-dihydroanthracene-1,9,10(4H)-trione (Q1) and 9,10-Dihydroxy-4,4-dimethyl-5,8-dihydro-1 (4H)-anthracenone (Q2), two molecules that inhibit cancer cell respiration, were selectively deuterated and dissolved ...
-
(ENDOCRINE SOC, 2008-06)Previous reports about the rat ovary have shown that cold stress promotes ovarian morphological alterations related to a polycystic ovary (PCO) condition through activation of the ovarian sympathetic nerves. Because the ...
-
(SOC BRASILEIRA QUIMICA, 2005-05)A systematic study about the long-range correlations observed in the HMBC spectra of a series of cis and trans 3-(4-oxo-4H-chromen-3-yl)-acrylic acid ethyl esters, and 5-hydroxy derivatives, was carried out. The results ...
-
(British Society for Neuroendocrinology, 2014)Oestrogens play an important role in development and function of the brain and reproductive tract. Accordingly, it is considered that developmental exposure to environmental oestrogens can disrupt neural and reproductive ...
-
(British Society for Neuroendocrinology, 2014)This review discusses the effects of stress and nutrition throughout development and summarises studies investigating how exposure to stress or alterations in nutrition during the pre-conception, prenatal and early ...
-
(Pleiades Publishing, 2015)In this study, we compare the results of experimental investigations of longitudinal and transverse pyroelectric effects in a chiral ferroelectric crystal. In a transverse geometry, we studied freely suspended liquid-crystal ...
-
(Centro de Investigaciones de Historia de la Medicina de la Universidad de Chile y de la Sociedad Chilena de Historia de la Medicina., 1963)
-
(Elsevier, 2016)The difference in host range between Salmonella enterica serovar Typhimurium(S. Typhimurium) and Salmonella enterica serovar Typhi (S. Typhi) can be partially attributed to the gain of functions, to the loss of functions ...
-
(Frontiers Media, 2021)Autism spectrum disorder (ASD) is a neurodevelopmental alteration characterized by social/communicative deficits, repetitive/stereotyped movements, and restricted/obsessive interests. However, there is not much information ...
-
(ENDOCRINE SOC, 2005-12)In the rat ovary, germ and somatic cells become organized into primordial follicles 48-72 h after birth. Although several genes have been implicated in the control of early follicular growth, less is known about the factors ...
-
(1997)The relationship between the metal-binding properties of metallothionein (MT) and its ability to interact with peroxides and free radicals was explored in vitro. The binding of 109Cd to MT and the thiol density of the ...
-
(Elsevier, 2015)Three cationic bis-cyclometallated iridium complexes [Ir(C^N-ppyMe)2(P^N)][PF6](1–3) with 4-methyl- 2-phenylpyridine (ppyMe) as the C^N-cyclometallated ligands and 8-(diphenylphosphino)quinoline (Ph2Pqn, L1), ...
-
(Springer, 2023)Airborne particulate matter is a serious threat to human health, especially in fast-growing cities. In this study, we carried out a magnetic and elemental study on tree leaves used as passive captors and urban dust from ...
-
(1996)The preparation of the copper(II) complex formulated as [Cu(DPA)(Ac)2]·2H2O is given (DPA: di(2-pyridyl)amine, Ac: acetate). The structure of this complex was determined by single-crystal X-ray analysis. It crystallizes ...
-
(SOC CHILENA QUIMICA, 2008-06)The preparation, magnetic characterization and antimicrobial properties of the complexes [Fe3O(CH3COO)(6)(CH3COOH)(H2O)]Cl(Melmid)center dot(H2O) (1) and [Fe4O2 (CH3COO)(7)O-2(BPA)(2)(H2O)]center dot Cl center dot ...

Magnetic behaviour of bimetallic layered phases M′0.2Mn0.8PS3·0.25 H2O (M′ = ZnII, CuII, NiII, CoII) (Royal Society of Chemistry, 2017)In this work the magnetic properties of bimetallic phases M'0.2Mn0.8PS3 center dot 0.25H(2)O (M' = Co-II, Ni-II, Cu-II or Zn-II) have been explored and compared with those of the pristine phase MnPS3. Magnetic susceptibility, ...
