Inverse relationship between scores on the quality of life questionnaire SF-12 and on the Aging Males' Symptoms scale in Italian men.

Objectives: To analyse the relation between results of the Aging Males' Symptoms (AMS) questionnaire for aging males, and of quality of life (QOL) questionnaire SF-12 and cardiovascular risk factors.

Methods: 1,927 men aged 55-85 years were interviewed by 56 general practitioners. During the interview the men were asked to fill in the AMS scale and the QOL questionnaire SF-12.

Two-photon absorption of Zn(II) octupolar molecules.

In this work we present an investigation of the non-linear optical (NLO) properties of two octupolar chromophores: [Zn(4,4'-bis(dibutylaminostyryl)-[2,2']-bipyridine)(3)](2+) and [Zn(4,4'-bis((E)-2-(N-(TEG)pyrrol-2-yl)vinyl)-[2,2']-bipyridine)(3)](2+) with Zn(ii) as the coordination center, using two-photon emission technique (TPE) in fs-pulse temporal regime. Compared to the free ligands, our results do not show a net increase in the two-photon absorption (TPA) cross-section for the octupolar complexes, once normalized to the ligand unit. This is in partial disagreement with a previous theoretical study investigating the first molecule where a significant increase of the TPA cross-section was predicted (X.
