Toll Like Receptors as Sensors of the Tumor Microbial Dysbiosis: Implications in Cancer Progression
2021
Microbiota is a complex ecosystem of active microorganisms resident in the body of mammals. Although the majority of these microorganisms resides at the distal gastrointestinal tract, high-throughput DNA sequencing technology have made possible to understand that several other tissues of the human body host their own microbiota, even those once considered sterile, such as lung tissue. These bacterial communities have important functions in maintaining a healthy body state and the host immune system has evolved multiple mechanisms by which maintaining a symbiotic relationship with the microbiota. The maintenance of this dialogue allows the induction of protective responses to pathogens and r…
Confocal laser scanning microscopy for the study of the morphological changes of the postextraction sites
2012
A better understanding of the remodeling process of postextraction sockets is essential in dental treatment planning. The aim of this study was to evaluate whether confocal laser scanning microscopy (CLSM) can be applied to imaging contour changes of postextraction sites, as well as to its quantification with image analysis of obtained three-dimensional images. This work describes a new application of the CLSM technique. The system used was the OLS3100-USS, LEXT model (Olympus((R))). CLSM was used for the surface analysis of the extraction site. The measurements taken with CLSM were: (1) mesio-distal distance, (2) alveolar ridge thickness, and (3) vestibular and lingual alveolar ridge heigh…

Polyphenols Epigallocatechin Gallate and Resveratrol, and Polyphenol-Functionalized Nanoparticles Prevent Enterovirus Infection through Clustering an…
2021
To efficiently lower virus infectivity and combat virus epidemics or pandemics, it is important to discover broadly acting antivirals. Here, we investigated two naturally occurring polyphenols, Epigallocatechin gallate (EGCG) and Resveratrol (RES), and polyphenol-functionalized nanoparticles for their antiviral efficacy. Concentrations in the low micromolar range permanently inhibited the infectivity of high doses of enteroviruses (107 PFU/mL). Sucrose gradient separation of radiolabeled viruses, dynamic light scattering, transmission electron microscopic imaging and an in-house developed real-time fluorescence assay revealed that polyphenols prevented infection mainly through clustering of…
Torrefioimalla käsitellyn puun varastoinnissa liukenevat yhdisteet
2016
Torrefiointi on uusi tapa käsitellä biomassaa. Torrefioitua biomassaa voidaan käyttää korvaaman fossiilisia polttoaineita korkealaatuista polttoainetta vaativissa voimalaitoksissa, joissa perinteisten biopolttoaineiden laatu ei riitä. Torrefiointi lisää biomassan energiatiheyttä ja tehollista lämpöarvoa merkittävästi. Kasvanut energiatiheys alentaa myös kuljetuskustannuksia verrattuna muihin biopolttoaineisiin. Tämän vuoksi torrefoidusta biomassasta, erityisesti torrefioiduista puupelleteistä on kaavailtu kivihiilen korvaavaa polttoainetta pölypolttolaitoksissa. Torrefioitujen puupellettien varastoitavuuden ja kosteuden keston oletetaan olevan tavallisia puupellettejä parempi, jolloin niitä…
Kolmivaiheisen pyrolyysiprosessin mallintaminen
2015
Työssä rakennetun mallin avulla määritettiin kolmivaiheisen hitaan pyrolyysiprosessin massa- ja energiavirrat. Mallissa reaktoriin syötettiin 2 kg tuoretta mäntyä, josta kuivausvaiheen jälkeen saatiin tuotteena 1 kg kuivaa puuta. Lämpötilassa 260 °C suoritetun torrefioinnin kiintosaanto oli 0,84 kg torrefiointiöljyn 0,13 kg ja kaasujen 0,04 kg. Hapan torrefiointiöljy sekä torrefiointikaasut johdettiin ulos prosessista ja torrefioitu puu pyrolysoitiin 450 °C:ssa, jolloin muodostui biohiiltä 0,28 kg, pyrolyysiöljyä 0,35 kg ja pyrolyysikaasuja 0,37 kg kiloa torrefioitua puuta kohti. Kuivausvaihe kulutti energiaa 3260 kJ/kg-tuore puu ja torrefiointi 619 kJ/kg-kuiva puu. Pyrolyysivaihe sen sijaa…
LEAVES OFNERIUM OLEANDERL. AS BIOACCUMULATORS OF POLYCYCLIC AROMATIC HYDROCARBONS (PAH) IN THE AIR OF PALERMO (ITALY): EXTRACTION AND GC-MS ANALYSIS,…
2005
Polycyclic Aromatic Hydrocarbons (PAH) were determined in the leaves of Nerium oleander L. an evergreen plant that occurs widely in both urban and rural areas, to monitor the degree of pollution in the urban area of Palermo (Italy) compared to remote areas. Twenty sites (urban roadside, urban, urban park, suburban and rural) in and around Palermo city were investigated. The purpose of this research was to investigate concentration levels and distribution patterns and relate them to possible sources. Analysis of 19 PAH was performed by gas chromatography/mass spectrometry (GCMS) using selected ion monitoring (SIM). The total amount of PAH ranged from 10 to 166 μg/Kg d.w. Each source gives ri…
Smart Wireless Sensor Networks and Biometric Authentication for Real Time Traffic Light Junctions Management
2013
The main challenge of intelligent transportation systems (ITS) is to deal with ‘real-time’ information to improve vehicular traffic management. Road data can be processed and used for dynamic traffic light management in order to reduce waiting times in queues. This paper proposes an innovative distributed architecture based on a wireless sensor network (WSN) with a network coordinator providing remote and ubiquitous authentication module for managing unexpected events. The architecture is completed by a dynamic module for street priority management depending on traffic rate. Many experimental trials have been carried out considering three different levels of traffic intensity to prove the e…
