WPŁYW FRAKCJI C IEKŁEJ POFERMENTU NA PROCES MEZOFILOWEJ FERMENTACJI METANOWEJ
PublicationBadano wpływ zawrotu frakcji ciekłej pofermentu na przebieg procesu fermentacji mezofilowej w bioreaktorach laboratoryjnych o pojemności całkowitej 10 dm3 w procesie quasi-ciągłym. Ba-dania prowadzono jednocześnie w dwu bliźniaczych reaktorach, z których pierwszy (R1) pełnił rolę układu referencyjnego a do drugiego (R2) podawano biomasę zawierającą frakcję ciekłą pofermentu. W trakcie prowadzonych badań nie zauważono istotnego...

The Imidazoacridinone Antitumor Drug, C-1311, Is Metabolized by Flavin Monooxygenases but Not by Cytochrome P450s.
PublicationPrezentowane w publikacji wyniki badań mają na celu wyjaśnienie roli enzymów wątrobowych w metabolizmie przeciwnowotworowych pochodnych C-1311 oraz C-1330. Oba związki inkubowane były z frakcją mikrosomalną oraz enzymami rekombinantowymi należącymi do grypy cytochromu P450, FMO oraz UGT. Badania wykazały, że oba związki są metabolizowane przez enzymy frakcji mikrosomalnej, ale nie przez enzymy cytochromu P450. Aktywność enzymatyczna...

Molecular mechanism of the enzymatic oxidation investigated for imidazoacridinone antitumor drug C-1311.
PublicationPraca miala na celu określenie molekularnego mechanizmu enzymatycznej utleniającej aktywacji wymienionego związku przeciwnowotworowego w takim układzie modelowym, w którym wcześniej wykazano jego kowalencyjne wiązanie się do DNA. Badania struktur chemicznych produktów enzymatycznej aktywacji wykazały, że dwa z nich powstają w wyniku dealkilacji łańcucha bocznego cząsteczki, natomiast dwa inne w wyniku aktywacji pierścienia imidazoakrydonu....

XPS study of the NH4-VOx powders
Open Research DataVanadium pentoxide samples were prepared by sol-gel method. The starting solution was prepared by mixing vanadium (V) oxytripropoxide (Aldrich) in an anhydrous ethanol as solvent and acetylacetone. By drying the sol at 323 K for 48 h, it transforms via gel into a xerogel powder. Next, the precursor powder was pressed into the disk-shaped pellets. Samples...

Analytical procedures for determination of cocaine and its metabolites in biological samples
PublicationThe dangerous effects and increased usage of illicit drugs have inspired the development of analytical methodologies. We based our review of analytical procedures for determination of cocaine (COC) and its metabolites on literature from the past two decades. Our main aim was to compare the capabilities of different analytical techniques. The diversity of matrices from which COC is determined (e.g., blood, hair, saliva, plasma,...

The New Chinese Civil Code and its contribution to Sustainable Development
PublicationThe first civil code of the People’s Republic of China in the history was adopted by the 13th National People’s Congress in Beijing on 28 May 2020 and will enter into effect on 1 January 2021. The new civil code puts much more emphasis on the sustainable development and protection of the environment and because of that, the Chinese private law has begun to respond to ecological problems as well. The...

The Impact of a New Product’s Novelty and Meaningfulness on its Commercial Performance
Publications new product development (NPD) process encompasses creative actions, so a new product is characterized by two essential dimensions used to describe any creative output – namely novelty and meaningfulness. Therefore, businesses are faced with the questions to what extent and under what market conditions to develop each of these dimensions in order to obtain high new product commercial performance. Based on gaps indentified in the...

Therapeutic Potential of Carnosine and Its Derivatives in the Treatment of Human Diseases
PublicationDespite significant progress in the pathogenesis, diagnosis, treatment, and prevention of cancer and neurodegenerative diseases, their occurrence and mortality are still high around theworld. The resistance of cancer cells to the drugs remains a significant problem in oncology today,while in the case of neuro-degenerative diseases, therapies reversing the process are still yet to be found. Furthermore, it is important to seek new...

Gendered entrepreneurship and its impact on firm innovativeness - a literature review.
PublicationEntrepreneurs gain a lot of attention in recent decades. Even if a precise definition of entrepreneur and entrepreneurship remains problematic, it is clear that there is a strong link between entrepreneurship and innovativeness, as well as between entrepreneur and innovation. In the current era of globalisation, the importance of innovations is as great as never before. And so is the importance of innovativeness determinants. Investigating...

The estimation of fish lenght distribution from its acoustical measures
PublicationThe paper concerns the problem of estimating fish length PDF from its target strength PDF obtained from acoustic surveys. It has been shown that the target strength of single fish can be treated in the first approximation as a finction of two variables: one, which depends on fish size and the other, which depends on its angular orientation (aspect). Extending this simplified relationship to the case of fish populations allows to...

Shipping Low Frequency Noise and Its Propagation in Shallow Water
PublicationOne of the most significant factor influencing acoustical climate of the sea is underwater noise generated by moving ships. If the considered sea area has features of the shallow water, namely the wave frequency fulfils relation f < 10c/h, where c denotes phase speed of sound, and h is depths of the sea, then in certain distance from the wave source specific image of sound pressure distribution in the mean of wave modes appears....
