Positive Interactions and Avoidant and Anxious Representations in Relationships with Parents, Friends, and Romantic Partners.

Journal of research on adolescence : the official journal of the Society for Research on Adolescence

Furman W, Stephenson JC, Rhoades GK.
PMID: 26346530
J Res Adolesc. 2014 Dec;24(4):615-629. doi: 10.1111/jora.12052.

We examined associations between positive interactions and avoidant and anxious representations in relationships with parents, friends, and romantic partners. Two hundred adolescents completed questionnaires, observations, and attachment interviews. From a between-person perspective, those adolescents with more positive interactions overall...

PMID: 27391276
Org Lett. 2016 Aug 05;18(15):3594-7. doi: 10.1021/acs.orglett.6b01601. Epub 2016 Jul 08.

A straightforward synthesis of pyrimido[4,5-d]pyridazines from pyrimidines and tetrazines under basic conditions is reported. Deprotonated, substituted 5-halopyrimidines readily react with variously substituted tetrazines in a highly regioselective manner via a complex reaction pathway, which was supported by DFT calculations....

Arrays of Molecular Rotors with Triptycene Stoppers: Surface Inclusion in Hexagonal Tris(o-phenylenedioxy)cyclotriphosphazene.

A new generation of rod-shaped dipolar molecular rotors designed for controlled insertion into channel arrays in the surface of hexagonal tris(o-phenylenedioxy)cyclotriphosphazene (TPP) has been designed and synthesized. Triptycene is used as a stopper intended to prevent complete insertion, forcing...

Ortop Traumatol Rehabil. 2002 Dec 30;4(6):694-702.

Background. Lower limb discrepancy (anisomelia) can be caused by many different factors leading to shortening (90% of cases) or lengthening of a limb (10% cases). This article present the results of densitometric tests performed on patients treated for lower...

Couples' Reasons for Cohabitation: Associations with Individual Well-Being and Relationship Quality.

Journal of family issues

[reaction: see text] We report the synthesis of cis-endo-bicyclo[1.1.1]pentane-1,2,3,4-tetracarboxylic acid and several of its derivatives with differentiated bridgehead and bridge positions, starting with tetracyclo[3.2.0.0(1,6).0(2,6)]heptane.

Metal-coordination-driven dynamic heteroleptic architectures.

Chemical Society reviews

Chem Soc Rev. 2010 May;39(5):1555-75. doi: 10.1039/b922293f. Epub 2010 Feb 15.

Dynamic heteroleptic coordination at metal centres is quite common in Nature and often related to a specific biological function, such as in zinc finger proteins and in hemoglobin for oxygen transport. To achieve the required high heteroleptic fidelity, representative...

Study of the 14Be continuum: identification and structure of its second 2+ state.
