Intestinal permeability and genetic determinants in patients, first-degree relatives, and controls in a high-incidence area of Crohn's disease in Southern Italy. Fries W, Renda MC, Lo Presti MA, Raso A, Orlando A, Oliva L, Giofré MR, Maggio A, Mattaliano A, Macaluso A, Cottone M. Dipartimento di Medicina Interna e Terapia Medica, Università di Messina, Messina, Italy. OBJECTIVE: A defect of gastrointestinal barrier function is considered to represent an important step in the pathogenesis of Crohn's disease (CD) but the mechanisms leading to an increased intestinal permeability (IP) are poorly understood. Since IP is influenced by pro-inflammat…

Selective chromo-fluorogenic detection of trivalent cations in aqueous environments using a dehydration reaction

2016

[EN] Trivalent cations (Al3+, Fe3+, Cr3+, As3+, In3+ and Ga3+) induced a dehydration reaction of a chemodosimeter in water that is coupled with colour and emission changes.

A dual channel sulphur-containing a macrocycle functionalised BODIPY probe for the detection of Hg(II) in a mixed aqueous solution

2018

We report herein the synthesis and chromo-fluorogenic behaviour of a new probe 1 containing a boron-dipirromethene (BODIPY) unit electronically connected with a dithia-dioxa-aza macrocycle. Acetonitrile and water-acetonitrile 95:5 v/v solutions of the probe showed an ICT band in the visible zone and are nearly non-emissive. When acetonitrile was used as solvent, addition of Hg(II) and trivalent metal cations induced an hypsochromic shift of the absorption band and moderate emission enhancements. A highly selective response was obtained when using competitive media such as wateracetonitrile 95:5 v/v. In this case only Hg(II) induced a hypsochromic shift of the absorption band and a marked em…
