H NMR Study of a Chiral Argentivorous Molecule/Ag Complex: Assignment of Proton Signals of Four Aromatic Rings with Slightly Different Environments.

The proton signals at the 2'- and 6'-positions of the aromatic side arms of a silver(I) complex with a chiral tetra-armed cyclen (()-) are assigned by comparison with H NMR spectra and X-ray structure of Ag complexes with three analogues of ()-: ()- having one benzyl group and three deuterium-substituted benzyl groups, ()- having two benzyl groups and two deuterium-substituted benzyl groups, and ()- having three benzyl groups and one 4'-fluorobenzyl group. An interaction factor is defined by using the X-ray structures. The chemical shift values of the proton signals in the aromatic side arms can be explained by using the interaction factors that are defined by the dihedral angles, the angles between two mean planes, and the CH···π distances from the X-ray data of the ()-/Ag complex.

Argentivorous Molecules Exhibiting Highly Selective Silver(I) Chiral Enhancement.

We report the synthesis of chiral tetra-armed cyclens, having an asymmetric center at one side-arm, that show selective chiral enhancement with silver(I). When the chiral ligand forms a silver(I) complex, the side-arms cover the silver(I) incorporated into the cyclen. The asymmetric center controls the conformation of the side-arms in one direction, increasing the molar ellipticity of the CD spectrum.

Accuracy of the cytopathology, bacterioscopy, and vaginal flora culture.

Introduction: An over-population of vaginal microorganisms causing inflammatory processes renders it difficult to properly assess the cytopathological exam that aims to screen precedent cervical lesions. On the contrary, the occurrence of the microbial flora saprophyte does not influence correct cythodiagnosis.

Objective: To assess the composition of vaginal tract aerobic microorganisms of asymptomatic women in menacme and post-menopause, and to analyze the accuracy of cytopathologic, bacterioscopic exams, and culturing of the flora.

Depth of glandular crypts and its involvement in squamous intraepithelial cervical neoplasia submitted to large loop excision of transformation zone (LLETZ).

Background: The authors aimed to confirm the depth of six mm in order to achieve an optimal eradication of the lesion.

Materials And Methods: This is a retrospective observational study of 94 cervical surgical pieces from women aged 17 to 22 years with a cyto-colpo-histopathological diagnosis of high-grade squamous cervical intraepithelial neoplasia (CIN II and/or CIN III) submitted to large loop excision of transformation zone (LLETZ). The glandular crypts and margins, both exposed or not to CIN, were assessed.

A case of cutaneous protothecosis in a polyarteritis nodosa patient and review of cases reported in Japan.

A 76-year-old woman farmer with a 20-year history of oral steroid treatment for polyarteritis nodosa, noted a rash consisting of numerous small papules on the dorsum of her right hand in February 2007. The rash worsened over time, and in April 2008 red papules and pustules as big as grains of rice fused to form plaques extending up her arm from the dorsum of the right hand to the extensor surface of the forearm. The plaques were accompanied by erosions, ulcers, and crusts.

Polymer-like structures of LiSCN, NaSCN, KSCN, RbSCN, and CsSCN complexes with an armed monoaza-15-crown-5 ether bearing a 3',5'-difluoro-4'-hydroxybenzyl group.

Structures of LiSCN, NaSCN, KSCN, RbSCN, and CsSCN complexes with 3',5'-difluoro-4'-hydroxybenzyl-armed monoaza-15-crown-5 ether (5) were investigated. The Li+ and Na+ complexes are (1:1)n polymer-like complexes bridged by hydrogen bonding. On the other hand, the K+, Rb+, and Cs+ complexes are polymer-like complexes bridged by the fluorine atoms of the side arms.

Interface design for indirect calorimetry in children with cerebral palsy.

The purpose of this study was to design, construct, and validate an alternative subject/instrument interface to collect metabolic data for individuals who, because of impairment, are unable to use a mouthpiece. An industrial designer directed the development of an interface design which would facilitate subject acceptance. A total of 13 subjects (eight children with cerebral palsy and five nonneurologically impaired) participated in the validation study.
