Tumours of Nasal Septum: A Retrospective Study of 32 Patients

2022

Objective: Tumours of the nasal septum are a rare and heterogeneous group of lesions in the sinonasal tract. The management of the different lesions of this site is debated. The aim of this study is to share our experience on a rare clinical condition and stimulate other centres to publish theirs. Methods: We retrospectively analysed the databases of sinonasal tumours treated at the Sections of Otolaryngology (ENT) of two University Hospitals (Palermo and Genova) between 2012 and 2020. Results: From the two databases, a cohort of 32 patients with tumours of nasal septum were selected. All patients underwent an endoscopic examination. Large tumours underwent preoperative computed tomography …

New insight on metal finds of the Punic Ship of Lilibeum

2020

In this paper, the investigation of some finds (two nails, a head and a long shaft nail, and a fragment of Lead sheathing) belonging to the wreck of the Punic ship and exhibited at Museo Archeologico Regionale Lilibeo (Trapani, Italy), is reported. The X-ray Fluorescence Spectroscopy (XRF) allowed us to identify the elements constituting them making some discussion deductions about their composition and degradation occurred.

Pickering Emulsion Gels Based on Halloysite Nanotubes and Ionic Biopolymers: Properties and Cleaning Action on Marble Surface

2019

We have fabricated ecocompatible Pickering emulsions based on halloysite nanotubes and ionic biopolymers (chitosan and pectin) from renewable resources. The effect of pectin and chitosan on the Pickering emulsion was investigated by direct visualization of the oil droplets and by the thermodynamic characterization at the interface. Pectin enhances the Pickering emulsion stability, while a phase separation and nonhomogeneous gel was observed in the presence of chitosan. We have demonstrated that the Pickering emulsion in a pectin based gel phase is suitable for wax layer removal from a marble surface. A controlled cleaning is achieved by tuning the contact time between the gel and the marble…

Environmental Organic Photochemistry: Advances and Perspectives

2013

This review is a survey of recent advances in environment related aspects of organic photochemistry. Besides presenting gen- eral concepts, the manuscript is mainly focused on the photoreactivity of natural organic matter, and on the photochemistry of anthropo- genic substances under natural light irradiation.

Photochemical sample treatment: A greener approach for PCBs analysis in sediments

2012

Electrical installations and industrial outlets are the major source in environment of chlorinated organic compounds. These are distributed in several geographical areas through long-range atmospheric transport and deposition. Additionally, chlorinated organic compounds can be introduced in the food chain and reach the consumers in very high levels. Besides toxicological studies on PCBs, recent research is focusing on more sophisticated analytical methods for PCBs detection. Distribution and dispersion of PCBs mostly occur through air, water, soils, and sediments. The latter are complex matrices whose analysis often involves costly extraction and purification procedures. In particular, PCBs…

Environmental Aspect Concerning Phthalates Contamination: Analytical Approaches and Assessment of Biomonitoring in the Aquatic Environment

2023

This review is a survey of recent progress in studies concerning the impact of phthalic acid esters in aquatic organisms. After introducing the classification, properties, sources, fate, and toxic effects related to phthalates, an overview of the techniques of extraction and analysis of these substances is provided. As a result, the general concepts of environmental bioindicators, biomonitoring systems, and other concepts related to phthalate contamination in the aquatic environment are presented. Recent bioaccumulation data of different phthalates are summarised in a table and organised according to the type of organism, tissue, and geographical area of sampling. Bioindicator organisms tha…
