Preživelost spor ekstremofilnih gliv izpostavljenih visokemu hidrostatskemu tlaku in prilagoditev na ustvarjene pogoje
Nina Recek, Željko Knez, Nina Gunde-Cimerman
Diplomsko delo
Oznake: ekstremofilne glive;spore;povišana slanost;visok hidrostatski tlak;mehanizmi prilagoditve;
Namen te diplomske naloge je določiti, kako izpostavitev spor izbranih ekstremofilnih vrst gliv visokemu hidrostatskemu tlaku vpliva na preživelost, rast, velikost in obliko glivnih kolonij po rasti na hranilnem mediju brez soli (MEA) ali na mediju z povečano koncentracijo soli (MEA+10% NaCl). Pri t ...

Advanced method for efficient functionalization of polymers by intermediate free-radical formation with vacuum-ultraviolet radiation and producing superhydrophilic surfaces
Alenka Vesel, Rok Zaplotnik, Miran Mozetič, Nina Recek
Izvirni znanstveni članek
Oznake: plasma treatment;vacuum-ultraviolet radiation treatment;surface functionalization;polymer polyvinyl chloride;vacuum-ultraviolet spectroscopy;vacuum-ultraviolet photons;
An efficient approach for tailoring surface properties of polymers is presented, which enables rapid modification leading to superhydrophilic properties. The approach is based on vacuum-ultraviolet radiation (VUV) pretreatment of the surface to create reactive dangling bonds. This step is followed b ...

ǂA ǂmethod for the immobilization of chitosan onto urinary catheters
Alenka Vesel, Nina Recek, Rok Zaplotnik, Albert Kurinčič, Katja Kuzmič, Lidija Fras Zemljič
Izvirni znanstveni članek
Oznake: polymer;chitosan immobilization;adhesion;plasma-surface modification;biopolymers;
A method for the immobilization of an antibacterial chitosan coating to polymeric urinary medical catheters is presented. The method comprises a two-step plasma-treatment procedure, followed by the deposition of chitosan from the water solution. In the first plasma step, the urinary catheter is trea ...

Protein adsorption on various plasma-treated polyethylene-terephthalate substrates
Nina Recek, Morana Jaganjac, Metod Kolar, Lidija Milković, Miran Mozetič, Karin Stana-Kleinschek, Alenka Vesel
Izvirni znanstveni članek
Oznake: oxygen and fluorine plasma treatment;polymer surface modification;protein adsorption;cell adhesion;quartz crystal microbalance;QCM;
Protein adhesion and cell response to plasma-treated polymer surfaces were studied. The polymer polyethylene terephthalate (PET) was treated in either an oxygen plasma to make the surface hydrophilic, or a tetrafluoromethane CF4 plasma to make the surface hydrophobic. The plasma source was radiofreq ...

Cell proliferation on polyethylene terephthalate treated in plasma created in SO[sub]2/O[sub]2 mixtures
Nina Recek, Matic Resnik, Rok Zaplotnik, Miran Mozetič, Helena Motaln, Tamara Lah Turnšek, Alenka Vesel
Izvirni znanstveni članek
Oznake:
Samples of polymer polyethylene terephthalate were exposed to a weakly ionized gaseous plasma to modify the polymer surface properties for better cell cultivation. The gases used for treatment were sulfur dioxide and oxygen of various partial pressures. Plasma was created by an electrodeless radio f ...
