(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 ...

(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, ...

(ELSEVIER, 2006-10-01)The structure and magnetic properties of two hybrid VPO compounds [(Cu(2)bipy(2))(2)V4O11(PO4)(2)]center dot 5H(2)0 1 and [Cu(2)phen(2)(O3PCH2PO3)(V2O5)(H2O)] center dot H2O 2 are reported. The magnetic behaviour of compound ...
-
(GORDON BREACH SCI PUBL LTD, 1995)In this contribution, magnetic investigations on materials, which essentially combine mesogenic and polymeric properties, were presented. In the glassy and the smectic phase of a copper(II) containing polymer we observed ...
-
(2010)Manganese dioxide (δ-MnO2) with magnetic properties has been synthesized by precipitation of MnO2 in the presence of magnetite. The resulting material has a particle size distribution between 0.5 and 5 μm. Magnetization ...
-
(2013)This paper describes the investigation and development of a novel magnetic drug delivery nanosystem (labeled as MO-20) for cancer therapy. The drug employed was oncocalyxone A (onco A), which was isolated from Auxemma ...
