Odorants of Capsicum spp. Dried Fruits as Candidate Attractants for Lasioderma serricorne F. (Coleoptera: Anobiidae)

2021

The cigarette beetle, Lasioderma serricorne F. (Coleoptera: Anobiidae) is an important food storage pest affecting the tobacco industry and is increasingly impacting museums and herbaria. Monitoring methods make use of pheromone traps which can be implemented using chili fruit powder. The objective of this study was to assess the response of L. serricorne to the volatile organic compounds (VOCs) from different chili powders in order to identify the main semiochemicals involved in this attraction. Volatiles emitted by Capsicum annuum, C. frutescens, and C. chinense dried fruit powders were tested in an olfactometer and collected and analyzed using SPME and GC-MS. Results indicated that C. an…

Cigarette Smoke Extract Induces p38 MAPK-Initiated, Fas-Mediated Eryptosis

2022

Eryptosis is a physiological mechanism for the clearance of senescent or damaged erythrocytes by phagocytes. Excessive eryptosis is stimulated under several pathologies and associated with endothelial injury and thrombosis. Cigarette smoke (CS) is an established risk factor for vascular diseases and cigarette smokers have high-levels of eryptotic erythrocytes. This study, for the first time, investigates the mechanism by which CS damages red blood cells (RBCs). CS extract (CSE) from commercial cigarettes was prepared and standardized for nicotine content. Cytofluorimetric analysis demonstrated that treatment of human RBCs with CSE caused dose-dependent, phosphatidylserine externalization an…

Superoxide generation by human neutrophils induced by low doses of Escherichia coli hemolysin.

1991

Escherichia coli hemolysin (Hly) was isolated from bacterial culture supernatants by polyethylene glycol precipitation and centrifugation in glycerol density gradients. The toxin preparations contained less than 1 mol of lipopolysaccharide per 10 mol of protein, and they had no fatty acids. The capacity of purified hemolysin to stimulate superoxide anion production in polymorphonuclear leukocytes was monitored kinetically in a lumimeter by using the lucigenin assay and was correlated with the kinetics of transmembrane pore formation. When applied to leukocytes suspended in protein-free buffer, very low concentrations (0.02 to 0.1 HU/ml) of the toxin strongly stimulated the production of sup…

Preliminary results about the breath of passive smokers and vapers based on the use of portable air monitoring devices

2016

Abstract Preliminary studies were made on the effect of both, classical smoking and electronic cigarettes (ECs) vaping, based on the quality of the indoor air and the breath of passive smokers. Portable air monitoring devices were used to evaluate carbon monoxide (CO), carbon dioxide (CO2), particulate materials (PM), formaldehyde and volatile organic compounds (VOCs) in indoor air and breath of active and passive smokers and vapers. As preliminary results, it can be observed that the major part of PMs liberated in classical smoking and ECs vaping correspond to the lowest size, which is the most dangerous for human health. However, the number of smallest PMs formed during vaping is around 5…

Il ruolo dell'organizzazione criminale nel contrasto al traffico illecito di tabacchi lavorati esteri

2019

the paper intends to analyze the features of the Italian criminal law on cigarette smuggling. The domestic system faces the illicit tobacco trade in a very peculiar way, especially if compared with the criminal law of other European countries (e.g. Germany, Greece, Portugal and Spain). The Italian strict regulation (artt. 291 bis, ter, quarter T.U.D.) could appear also unreasonable if set side by side with the domestic legislation on smuggling of goods. Indeed, the latter is characterized by a large use of administrative sanctions instead of the severe criminal penalties related to the cigarette smuggling. The paper aims at demonstrating that the domestic firm method is based on the will to…

Aspects typo-chronologiques et archéométriques de la céramique africaine sur le territoire de Cignana (Naro, AG, Sicile)

2017

Ce projet de recherche se fonde sur une étude typologique et archéométrique des matériaux d’époque romaine-impériale collectés pendant les prospections, surtout les céramiques africaines importées en Sicile entre la fin du Ier et le VIIe siècle apr. J.C. On ne va pas se concentrer sur une seule classe de céramique mais on va analyser globalement tous les objets manufacturés (amphores, sigillées, vaisselles culinaires, communes, lampes) en adoptant une approche diachronique correspondant à l’entière période de circulation de ces céramiques. L’objectif est de reconstruire les contacts économiques entre les deux provinces et individualiser l’origine des différentes productions. Nous allons ess…

Dinamiche insediative nel comprensorio di Cignana. Continuità e discontinuità tra l'età imperiale e l'età bizantina

2013

The aim of this paper is to illustrate the development of rural settlement of Roman age, in the hinterland of Cignana (close to Agrigento, Sicily). In this area were identified an Early Roman age villa and a Late Roman/Byzantine village, partially excavated by the Superintendence of Agrigento. Since 2007 the Dep. of Beni Culturali of University of Palermo has carried out an intensive and systematic archaeological survey around Cignana, where about 200 archaeological sites were identified. Many sites (farms, and perhaps also some villa) were inhabited from late Hellenistic to Late Roman/Byzantine ages, and some have become very large villages; also, many settlements are placed along the prin…
