Several 9-(2-aminoethyl)anthracene derivatives were prepared with different nitrogen substitutents including alkyl, acetamide, trifluoroacaeamide and t-butyl carbamate. The selectivity in Diels-Alder cyclodaddition reaction with N-methyl maleimide was evaluated through single crystal X-ray analysis of the products. Models for the change...

The systemic circulation offers larger resistance to the blood flow than the pulmonary system. Consequently, the left ventricle (LV) must pump blood with more force than the right ventricle (RV). The question arises whether the stronger pumping action of...

Fragments of layered manganese oxide are the real water oxidation catalyst after transformation of molecular precursor on clay.

A binuclear manganese molecular complex [(OH2)(terpy)Mn(μ-O)2Mn(terpy)(OH2)](3+) (1) is the most prominent structural and functional model of the water-oxidizing Mn complex operating in plants and cyanobacteria. Supported on montmorillonite clay and using Ce(IV) as a chemical oxidant, 1 has been...

Chemoselective silicification of synthetic peptides and polyamines.

Beilstein J Nanotechnol. 2015 Jan 08;6:103-10. doi: 10.3762/bjnano.6.10. eCollection 2015.

Biosilicification sets the standard for the localized in vitro precipitation of silica at low orthosilicate concentrations in aqueous environment under ambient conditions. Numerous parameters must be controlled for the development of new technologies in designing inventive nanosilica structures, which...

What is the role of the voice in Indian explanatory models of madness and psychiatric nosology? Anthropological and psychiatric challenges, it is argued, are crystallised in the voice, a medium that signifies the intersection of models of occult madness...

Biological variation of canine serum thyrotropin (TSH) concentration.

Veterinary clinical pathology

Iversen L, Jensen AL, Høier R, Aaes H.
PMID: 12075532
Vet Clin Pathol. 1999;28(1):16-19. doi: 10.1111/j.1939-165x.1999.tb01036.x.

The aim of the present study was to estimate the between-dog, within-dog and analytical components of variance for serum thyrotropin (TSH) in healthy dogs, and to use these components of variance to 1) estimate the critical difference for significance...
