(Lippincott Williams & Wilkins, 2016)Objective: To identify novel biomarkers associated with pediatric primary hypertension. Methods: We recruited 350 participants (4-16 years). Anthropometric parameters and aldosterone, plasma renin activity, cortisol, ...
-
(Nature, 2020)The renin–angiotensin system is an important component of the cardiovascular system. Mounting evidence suggests that the metabolic products of angiotensin I and II — initially thought to be biologically inactive — have ...

Counterion and composition effects on discotic nematic lyotropic liquid crystals - I. Size and order (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2007-12-01)Counterion and composition effects on the size and interface dynamics of discotic nematic lyotropic liquid crystals made of tetradecyltrimethylammonium halide (TTAX)-decanol (DeOH)-water-NaX, with X = Cl- and Br-, were ...
-
(Elsevier B.V., 2017)Co-doped stannates, Zn2-xCoxSnO4(0.5 <= x <= 1.5), were produced by ceramic synthesis starting from the ZnSnO4 phase. Morphology, structure, and composition of synthesized compounds were examined using scanning electron ...
-
(Elsevier, 2012-02-03)In the present work three different SPME fibers have been investigated for simultaneous determination of methyl-, butyl- and phenyltins by using gas chromatography-pulsed flame photometer detection (GC-PFPD). The optimal ...
-
(Royal Society of Chemistry, 2014)In the present work, the synthesis and structural characterization of four new polyoxovanadoborate (BVO) frameworks based on the [V12B 18O60H6]10- polyanion are reported: (NH4)8(1,3-diapH2)[V12B 18O60H6]·5H2O (1), K ...
-
(2006)The ionic cobalt (II) title complex [Co2(OH)2 (Ac)3(Bipy)2]·K·2(H2O) (where Ac: Acetate, Bipy: 2,2-bipyridine) consists of anionic bimetallic unit in which cobalt ions are bridged by hydroxo and acetate ligands, balanced ...
-
(2009)A structural and magnetic characterization of a trinuclear chiral Mn(ll) formate three-dimensional framework exhibiting a triangular arrangement is presented. Compound Na3[Mn3(HCOO)9] was obtained by solvothermal synthesis ...
-
(SOCIEDAD CHILENA DE QUIMICA, 1998-12)The crystal structure of C42H37O3P2Br has been determined by single crystal X-ray diffraction. The title compound is monoclinic, space group P2(1)/n (Nr. 14), with unit cell parameters a = 11.220(6), b = 14.345(10), c = ...
-
(2014)4,40-(Disulfanediyl)dibutanoic acid (dtba) and 4,40-bipyridine (4,40-bpy) crystallize in an 1:1 ratio, leading to the title co-crystal with composition C8H14O4S2 C10H8N2. A distinctive feature of the crystal structure ...
-
(SOCIEDAD CHILENA DE QUIMICA, 1998-12)An X-ray diffraction study of the 7-bromo-5,8-dihydroxy-4,4-dimethyl-4H-naphthalen--1-one (1), obtained by bromination of 5,8-dihydroxy-4.4-dimethyl-4H-naphthalen-1-one with molecular bromine, gave unambiguous proof of its ...
-
(2014)The structure of the title compound [Sm2(crot)6(H2O)4]2·3(H2O) (I), (crot= crotonate = butenoate = O2CCHCHCH3)] consists of two independent, centrosymmetric dimeric units, of similar composition but diverse coordination, ...
-
(2014)The asymmetric unit of the title compound, C8H9NO2 H2O consists of an isolated 4-(ammoniomethyl)benzoate zwitterion derived from 4-aminomethylbenzoic acid through the migration of the acidic proton, together with a ...
