Solid-state polymer membranes for simple, sensitive, and low-cost monitoring of mercury in water.

Solid-state Hg(II) selective membranes were produced and assessed by means of X-ray absorption near edge structure in the total reflection X-ray fluorescence (TXRF-XANES) setup and by the energy dispersive X-ray fluorescence (EDXRF) technique. Membranes were functionalized using four promising ligands for mercury complexation, i.e.

Characterization of Photoactive Fe-TiO Lime Coatings for Building Protection: The Role of Iron Content.

Iron-doped TiO nanoparticles, ranging in Fe concentrations from 0.05 up to 1.00% w/w, were synthesized through a simple sol-gel method.

Application of multispectral imaging detects areas with neuronal myelin loss, without tissue labelling.

The application of multispectral imaging to discriminate myelinated and demyelinated areas of neural tissue is herein presented. The method is applied through a custom-made, multispectral imaging monochromator, coupled to a commercially available microscope. In the present work, a series of spinal cord sections were analysed derived from mice with experimental autoimmune encephalomyelitis (EAE), an experimental model widely used to study multiple sclerosis (MS).

A clinical study of optical biopsy of the uterine cervix using a multispectral imaging system.

Objective: To present the clinical application of the multispectral imaging colposcopic system (MIS colposcopy).

Methods: MIS colposcopy was performed on 123 enrolled women. After a 3% acetic acid application, sequential images were captured, analyzed, and stored automatically.

In vivo fluorescence kinetics and photodynamic therapy in condylomata acuminata.

Background: Topical application of 5-aminolaevulinic acid (ALA) to condylomata acuminata leads to accumulation of protoporphyrin IX (PpIX); therefore ALA-induced photodynamic therapy (ALA-PDT) appears to be a potential treatment.

Objectives: To investigate in vivo the PpIX fluorescence time course after topical application of ALA in order to determine the optimal time for irradiation, and to assess the efficacy of subsequently performed ALA-PDT.

Methods: Fluorescence kinetics was studied in 12 male patients with condylomata acuminata.
