NMR Metabolomics Study of the Association between Pancreatic Cancer and Diabetes Mellrtus.
Michálková, Lenka; Horník, Štěpán; Sýkora, Jan; Habartová, L.; Setnička, V.
2019 - English
In our study, 1H NMR metabolomics was employed to plasma samples of pancreatic cancer patients, individuals with long-term diabetes mellitus type 2 (lasting more than 5 years) and healthy controls. The NMR analyses were followed by establishing a statistical model based on principal component analysis and discriminant analysis. The aim was to discover differences between these groups and to define a potential biomarker panel. The statistical evaluation of metabolomics-based profiles provided high values of sensitivity and specificity. Subsequently, plasma samples of the risk group, specifically patients with recently diagnosed diabetes mellitus with a duration of <3 years (possible T3cDM), were analysed and the possibility of PC development was predicted. The achieved results showed strong potential of 1H NMR metabolomics to establish a biomarker panel that would facilitate the early diagnosis of PC and the possibility identify diabetic individuals, who are at risk of developing PC.

Dialytic Separation of Anions from DMSO Solution Facilitated by dendritic Receptors.
Cuřínová, Petra; Winkler, Maximilian; Krupková, Alena; Budka, J.; Wun, Ch.N.; Blechta, Vratislav; Červenková Šťastná, Lucie; Sýkora, Jan; Strašák, Tomáš
2019 - English
As the dialytic tubing is impermeable for big molecules of receptor, the anions crossing the barrier of dialytic tubing to form complex with the receptor stay entrapped inside and can be removed from the solution. NMR methods were used to study the complexation properties of given receptors as well as to determine the concentration changes during dialytic experiments.

Influence of Surface Treatment of Thin-Film Composite Membrane on Separation of Carbon Dioxide from Biogas.
Morávková, Lenka; Kárászová, Magda; Petrusová, Zuzana; Izák, Pavel
2019 - English
The effect of the various wetting procedure on the membrane performance was studied [1]. Spraying is clearly more efficient than spreading water on the top of the membrane with a brush and results in higher methane purity. Spraying ensures a more uniform distribution of the water on the skin layer of the membrane, leading to much higher CO2 permeation through the membrane and higher CH4 content in the retentate stream.

Preparation of antibacterial electrospun scaffold for skin cells culture.
Bajsić, E.G.; Veceric, M.; Zdraveva, E.; Mijović, B.; Grgurić, T.H.; Ujčić, Massimo; Trcin, M.T.; Slivac, I.
2019 - English
In this work the function and application of titanium dioxide as a filler in a composite system polycaprolactone/titanium dioxide (PCL/TiO2) was examined. Titanium dioxide was applied by ultrasonic bath on already electrospun PCL fibrous scaffold treated and non-treated with NaOH. A procedure of surface modification of the electrospun PCL fibrous scaffold was made to enhance the interaction of the surface with the TiO2 particles. The surface modification was performed using NaOH for the formation of carboxyl groups on the fibers' surfaces. The water contact angle was measured by goniometer to prove the change from hydrophobic to hydrophilic polymer surface. SEM was used to study the morphology structure of the electrospun PCL fibrous scaffold before and after NaOH treatment and introduction of TiO2. The content of TiO2 on the electrospun PCL fibrous scaffold was determined by TGA. After NaOH treatment the surface of the electrospun PCL fibrous scaffolds changed from hydrophobic to hydrophilic. SEM micrographs show that with the sonification of 30 min homogeneous TiO2 particles distribution was obtained, while after sonification of 60 min, the TiO2 particles tend to agglomerate. The modification of the scaffold surface with NaOH enhances the adhesion of the TiO2 filler. TG analysis show that longer treatment of the electrospun PCL fibrous scaffolds in the ultrasonic bath gives lower thermal stability. The time of 30 minutes in the ultrasonic bath is optimal to provide sufficient amount of the TiO2 particles on the electrospun PCL fibrous scaffold.

Hydrotreating over Silica-Alumina Supported Catalysts
Gulková, Daniela; Vít, Zdeněk; Kaluža, Luděk
2019 - English
They are studied for possible use in deep hydrodesulfurization (HDS)1 while they have not been investigated for the HDS parallel with hydrodeoxygenation (HDO)2. The aim was to find the effect of active phase and support of Pd and PdPt catalysts on activity and selectivity in HDS of 4,6-dimethyldibenzothiophene (DMDBT) and HDS/HDO of l-benzothiophene/octanoic acid (BT/OA).
