INTRODUCTION: The identification of early, preferably presymptomatic, biomarkers and true etiologic factors for Alzheimer's disease (AD) is the first step toward establishing effective primary and secondary prevention programs. Consequently, the search for a relatively inexpensive and harmless biomarker for...

Mechanistic investigations of imine hydrogenation catalyzed by cationic iridium complexes.

Chemistry (Weinheim an der Bergstrasse, Germany)

PMID: 16534823
Chemistry. 2006 May 15;12(15):4043-56. doi: 10.1002/chem.200501230.

Complexes [IrH2(eta6-C6H6)(PiPr3)]BF4 (1) and [IrH2(NCMe)3(PiPr3)]BF4 (2) are catalyst precursors for homogeneous hydrogenation of N-benzylideneaniline under mild conditions. Precursor 1 generates the resting state [IrH2{eta5-(C6H5)NHCH2Ph}(PiPr3)]BF4 (3), while 2 gives rise to a mixture of [IrH{PhN=CH(C6H4)-kappaN,C}(NCMe)2(PiPr3)]BF4 (4) and [IrH{PhN=CH(C6H4)-kappaN,C}(NCMe)(NH2Ph)(PiPr3)]BF4 (5), in...

Assessment of angle velocity in girls with adolescent idiopathic scoliosis.

Scoliosis

Scoliosis. 2009 Sep 16;4:20. doi: 10.1186/1748-7161-4-20.

BACKGROUND: Although it has been demonstrated that the peak height velocity (PHV) is a predictive factor of progression in adolescent idiopathic scoliosis (AIS), little is known about the usefulness of angle progression in clinical practice. The purpose of this...

Spanish "fine tuning" of language to describe depression and anxiety.

Journal of palliative medicine

Noguera A, Centeno C, Carvajal A, Tejedor MA, Urdiroz J, Martínez M.
PMID: 19591617
J Palliat Med. 2009 Aug;12(8):707-12. doi: 10.1089/jpm.2009.0024.

On screening tools for emotional distress, the terms "depression" and "anxiety" are commonly used for patients with advanced cancer. However, these terms could have negative connotations in Spanish such that cultural and unexpected differences in perception may invalidate or...

The synthesis of two new tritopic double-scorpiand receptors in which two equivalent 5-(2-aminoethyl)-2,5,8-triaza[9]-(2,6)-pyridinophane moieties have been linked with 2,6-dimethylpyridine (L1) or 2,9-dimethylphenanthroline (L2) units is reported for the first time. Their acid-base behaviour and Zn(2+) coordination chemistry have been...

Enantiopure 2-thia-4-azabicyclo[3.1.0]hexanes, which can be considered constrained cysteines, have been obtained from l-cysteine by application of the "self-regeneration of chirality" concept. The key intermediates are homochiral thiazolines that can be prepared in multigram scale and react smoothly with a...
