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. Keywords: anions; receptor; dialytic experiments Available in a digital repository NRGL

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.

Hydrodynamic Behavior of Large Bubbles inSlot Channels.
Ezeji, Kingsley
2019 - English
We present the results of experimental investigation on the dy-namics of air bubbles rising in stagnant or co-flowing liquid insidean inclined rectangular channel. Variable channel geometry (withadjustable height𝐻, perimeter𝑃 = 2(𝐻 + 𝑊), inclination𝛼, and orien-tation – flat𝐻 < 𝑊or tall𝐻 > 𝑊) enabled us to evaluate the influenceof different operation parameters on the bubble shape and velocity. Measurements of the rise velocity of large Taylor bubbles (𝑈TB) werecarried out by using a high-speed video camera system and an imageprocessing technique. Keywords: gas bubble; slot channels; experimental investigation Available in a digital repository NRGL
