Cell permeabilization and viability dependence on the pulse amplitude was determined by twenty different sets of electrical parameters. The number of pulses varied between 1 and 64 and pulse duration between 20 micros and 1 ms. The most important parameter was the pulse amplitude because at triggered the electropermeabilization process and the process of cell death. Either in the case of electropermeabilization as well as in the case ofcell viability experiments, the parameter Uso (the pulse amplitude leading to permeabilization or to the death of 50% of cell population) was not changedif the set of electrical parameters consisted of more than 16 pulses. This was independent of the pulse duration. The efficiency of permeabilizationwas enhanced by using of longer pulses. Such a systematic study of the influence of different electric field parameters on electropermeabilization and cell viability may serve as a base for optimization of the electropermeabilization conditions for different applications</dc:description><dc:description xml:lang="sl">V članku predstavljamo sistematično študijo vloge različnih električnih parametrov (število, trajanje in amplituda električnih pulzov) v procesu elektropermeabilizacije celic DC3F za majhne molekule in vpliva teh parametrovna preživetje celic. Permeabilizacijo celic in njihovo preživetje smo določili za dvajset različnih naborov električnih pulzov. Število električnih pulzov smo spreminjali od 1 do 64, njihovo trajanje pa med 20 mikros in 1 ms. Najpomembnejši električni parameter je amplituda električnih pulzov, saj sproži proces elektropermeabilizacije in proces umiranja celic. Tako v primeru elektropermeabilizacije celic kot tudi ob študiju celičnega preživetja smo ugotovili, da se parameter U5o (tj. amplituda električnih pulzov pri kateri je permeabiliziranih (ali mrtvih) 50% celic v populaciji) nespremeni, če uporabljeni vlak električnih pulzov sestavlja več kot 16 električnih pulzov. Ugotovitev je neodvisna od njihovega trajanja. Perrneabilizacija je učinkovitejša, če uporabimo daljše električne pulze. Takosistematično študijo vpliva električnih parametrov na elektropermeabilizacijo in preživetje celic lahko uparabimo kot osnovo za optimizacijo elektropermeabilizacijskih pogojev pri različnih aplikacijah elektropermeabilizacije</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-HH258JRE"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-HH258JRE" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-HH258JRE/2fac72f3-6d97-49e5-8cbf-cf034610f3f9/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by/4.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Društvo radiologije in onkologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-HH258JRE/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-HH258JRE" /></ore:Aggregation></rdf:RDF>
