Zinc oxide nanorod based immunosensing platform for the determination of human leukemic cells.
2019
Zinc oxide (ZnO) based nanostructures owing unique physical properties – high photoluminescence, bio- compatibility and other characteristics, therefore, they attract attention as building blocks suitable for biosensor development. In this research as a target we have used human leukemic cell line IM9 (IM9). IM9 was derived from the patient with a multiple myeloma and expressed cluster of differentiation proteins СD19 on the surface of 85–95% here investigated cancer cells. As a control sample healthy human's peripheral blood mononuclear cells (PBMC) were used and the expression of CD19 protein was found only in 5–9% of these cells. Two types of antibodies labeled by f…
Endocytosis in skeletal muscle fibers.
1999
Defining the organization of endocytic pathway in multinucleated skeletal myofibers is crucial to understand the routing of membrane proteins, such as receptors and glucose transporters, through this system. Here we analyzed the organization of the endocytic trafficking pathways in isolated rat myofibers. We found that sarcolemmal-coated pits and transferrin receptors were concentrated in the I band areas. Fluid phase markers were taken up into vesicles in the same areas along the whole length of the fibers and were then delivered into structures around and between the nuclei. These markers also accumulated beneath the neuromuscular and myotendinous junctions. The recycling compartment, lab…
Performances and morphology of polyamide/carbonaceous structures based fibers
2014
In this work the influence of carbonaceous particles with different particle sizes and shapes on the morphology and mechanical performances of polyamide (PA) based fibers was investigated. Graphene nanoplatelets (GNP) are compared with spherical and rod-like carbon fillers such as carbon black (CB) and multiwall carbon nanotubes (MWCNT). The different morphologies of the particles control their dispersion and their alignment in PA fibers upon elongational flow action and play a key role in structure-property relationships.
Taking advantage of the functional synergism between carbon nanotubes and graphene nanoplatelets to obtain polypropylene-based nanocomposites with en…

Carbon Nanotubes (CNT) and Graphene Nanoplatelets (GNP) were incorporated in Polypropylene (PP) as single filler (CNT=1, 2 and 4 %wt. and GNP=2, 4, and 6 %wt.) and in hybrid form (CNT:GNP weight ratio 2:2, 2:4 and 4:2) using a prototype miniature Twin Screw Extruder (TSE) coupled with a double slit rheological die, in order to assess in-line the extent of nanofiller dispersion and to deliver PP-based nanocomposites with enhanced thermo-oxidative stability. The morphological, electrical and mechanical properties, as well as the resistance to thermal and photo degradation of the composites containing single nanofillers (PP/CNT and PP/GNP) were compared with those of hybrid PP based nanocompos…

Effect of the nanotube aspect ratio and surface functionalization on the morphology and properties of multiwalled carbon nanotube polyamide-based fib…
2013
In this study, the effect of the carbon nanotube (CNT) aspect ratio and surface functionalization on the mechanical behavior and morphological changes of polyamide (PA)-based fibers was investigated. Composites were prepared by the melt blending of CNTs with PA, and at a later time, the fibers were prepared by melt spinning and cold drawing. A reinforcement effect was noticed for all of the CNTs samples, and the increase in the mechanical properties and dimensional stability was more pronounced for highly oriented filaments. When the elongational flow was increased, the orientation of CNTs along the fiber direction was observed, but the nanotube alignment was much more difficult for CNTs wi…
Il delitto di apostasia alla luce del motu proprio "omnium in mentem"
2012
Il lavoro si propone di analizzare le conseguenze dirette e, soprattutto, indirette della riforma del Codice di diritto canonico realizzata col Motu proprio Omnium in mentem. Tale provvedimento normativo,avente ad oggetto la possibilità di separarsi con atto formale dalla Chiesa, rischia, al di là delle intenzioni del legislatore, di avere delle serie ripercussioni sulla configurabilità del delitto di apostasia dalla fede. L'articolo indaga su tutte le possibili implicazioni giuridiche della citata riforma, evidenziando la poca organicità della stessa e il suo impatto sulla struttura codicistica del 1983.
Lasten ryhmäperustainen, verbaalis-kognitiivinen motoriikkaharjoittelu : interventiotutkimus
2010
Tutkimuksen tarkoituksena oli selvittää miten opettajat pystyvät seulomaan yleisopetuksen alaluokilta lapsia, joilla on lieviä motorisen oppimisen vaikeuksia. Lisäksi tutkittiin 10 viikkoa kestäneen motoriikkaa kuntouttavan kognitiivisen harjoitusohjelman vaikutuksia. Kolmantena teemana oli motivaation ja mielialan kehittyminen kerhokerran aikana. Harjoitusohjelma toteutettiin koulun iltapäiväkerhona eräässä keskisuomalaisessa koulussa lukuvuonna 2009–2010. Osallistujat seulottiin neljältä alaluokalta (1–2lk) opettajien täyttämällä koordinaatiokyselyllä (Developmental Coordination Disorder -Questionnare, DCDQ ). Harjoittelun vaikutuksia selvitettiin alku-, loppu- ja pysyvyysmittauksilla, jo…
