This study investigates the antibacterial effect of silver ions on Escherichia Coli and Bacillus Subtilis. It aims to clarify the correlation between the silver ion concentration and the antibacterial effect. The well diffusion method was used in the experiment, where five different concentrations of silver ions were examined (0, 1, 5, 20 and 50 mM). Every concentration was tested 12...

Although categorizing stimuli is a basic cognitive ability, the neural mechanisms of categorization and category learning are poorly understood. Here, we conducted a proof of concept experiment and were able to show that mice can learn categorization of auditory stimuli. This allows us to use mice as an animal model for future categorization studies. We further investigated connections in the...

In recent years, the occurrence of HABs - harmful algae blooms - in freshwater systems have become more frequent, as water temperatures are rising due to global warming. These blooms are formed by fast reproducing algae or cyanobacteria and can have serious consequences for aquatic organisms, as some bloom forming species produce toxins that inhibit the growth of other aquatic...

This project is a study of the Triops cancriformis egg resistance to high temperatures and the analysis of its chemical composition by thermal analysis up to 1000ºC and observation with scanning electron microscope. This would explain why it has survived the great extinctions of our planet and why it is considered a living fossil retaining the same appearance as more...

We investigated the modifications of the pH of the cell culture medium in the environment of cancer cells with the aim of finding a new anti-cancer therapy. We tried to find out the ideal pH for performing anti-cancer therapy procedures and apply it to SKBR3 cells. From the observed results, we concluded that the ideal pH for our proposed therapy...

How much alcohol is too much? Public health requires a guideline to incentivise responsible teenage vodka consumption and prevent irreversible liver damage. This study attempted to determine a safe concentration by immersing 1.0g pig liver pieces in a 37°C water bath with different vodka concentrations serially diluted. Vodka and hydrogen peroxide volume and mass of pig liver were controlled amongst...

Large quantities of the antibiotic florfenicol are used in animal farming and aquaculture, contaminating the ecosystem with antibiotic residues and promoting antimicrobial resistance, ultimately leading to untreatable multidrug-resistant pathogens. Marik Müller has devised new strategies for enzymatic inactivation of florfenicol before it enters the environment. Using molecular evolution, he improved a hydrolase enzyme, produced it in bacteria and studied its...

Non-conventional yeasts and their enzymes are scarcely studied but they could have unique characteristics with biotechnological applications which are uncommon for enzymes of bakers’ yeast. α-Glycosidases are enzymes which hydrolyze sugars, but some of them synthesize short saccharides. The aim of the study was to characterize the activities and biochemical parameters of α-glucosidase AG2 (BaAG2) from evolutionally old yeast Blastobotrys...

The most accurate method for studying DNA replication is the labeling of newly synthesized DNA molecules with halogenated nucleosides followed by immunofluorescence and microscopy detection, known as DNA fiber labeling. The major difficulty of the method is the labor-intensive analysis, which requires measuring the lengths of a large number of labelled fragments. There are very few attempts to automate this...

A microfluidic pump (MFP) is designed in professional drawing program AutoCAD and produced by using 3D printer in this project. It is aimed to develop microfluidic pump which is cost-effective and has practical usage during the treatment processes of diseases such as cancer and diabetes. During the experiments we characterized our pump and examined that uniquely designed MFP has suitable...
