Lawesson's reagent (LR) for direct thionation of hydroxamic acids. Substituent effect on LR reactivity
PublikacjaOkreślono zakres stosowalności i ogranicznia metody bezpośredniej tionacji kwasów hydroksamowych (HAA) za pomocą odczynnika Lawessona (LR). Przedmiotem badań było 35 HAA o wzorze ogólnym R1CON(R2)OH gdzie: R1 = alkil, aryl, benzyl, etoksykarbonylometylen, cynamyl, heteroaryl, a R2 = alkil, aryl. Ustalono, że wydajności kwasów tiohydroksamowych są niskie, gdy wyjściowy HAA posiada w swojej strukturze duże objętościowo reszty R1...

A Colorimetric Microplate Assay for DNA-Binding Activity of His-Tagged MutS Protein
PublikacjaA simple microplate method was designed for rapid testing DNA-binding activity of proteins. The principle of the assay involves binding of tested DNA by his-tagged protein immobilized on a nickel-coated ELISA plate, following colorimetric detection of biotinylated DNA with avidin conjugated to horseradish peroxidase. The method was used to compare DNA mismatch binding activities of MutS proteins from three bacterial species. The...

Influence of accelerometer signal pre-processing and classification method on human activity recognition
PublikacjaA study of data pre-processing influence on accelerometer-based human activity recognition algorithms is presented. The frequency band used to filter-out the accelerometer signals and the number of accelerometers involved were considered in terms of their influence on the recognition accuracy. In the test four methods of classification were used: support vector machine, decision trees, neural network, k-nearest neighbor.

Activity and discrimination against women in the labour market in the countries of Baltic Sea Region
PublikacjaAn increasing participation of women in the labour market seem to be a key to overcome the problems of the EU labour market and to achieve the objectives of Strategy Europe 2020. Therefore, the objective of this paper is to identify differences in the situation of women in the labour market in selected countries such as those in the Baltic Sea region and to attempt to verify the hypothesis of the existence of discrimination against...

Structural determinants of imidazoacridinones facilitating antitumor activity are crucial for substrate recognition by ABCG2
PublikacjaW pracy zidentyfikowaliśmy elementy struktury chemicznej dla 23 pochodnych imidazoakrydonu odpowiedzialne za ich rozpoznawanie przez transporter typu ABC, białko ABCG2. za transport tych związków przez pompę ABCG2 odpowiedzialne jest grupa hydroksylowa w pozycjach R1, R2 i R3 chromoforu. Stwierdziliśmy także, że zwiększanie ilości grup metylenowych łańcucha bocznego imidazoakrydonów powodowało zmniejszenie aktywnego transportu...

Actions of a nitric oxide donor on prostaglandin production and angiogenic activity in the equine endometrium
PublikacjaNitric oxide (NO) plays an important role in prostaglandin secretion and angiogenesis in the reproductive system. In the present study, the roles of the NO donor spermine NONOate and tumour necrosis factor-alpha (TNF; as a positive control) in prostaglandin production and angiogenic activity of equine endometria during the oestrous cycle were evaluated. In addition, the correlation between NO production...

Preparation and photocatalytic activity of boron-modified TiO2 under UV and visible light
PublikacjaOtrzymano TiO2 domieszkowany borem i wyznaczono jego aktywność fotokatalityczną w zakresie światła UV i Vis. Katalizatory otrzymano metodą zol-żel lub poprzez ucieranie dwutlenku tytanu z prekursorami B. Jako źródło boru zastosowano kwas borowy lub ester trietylowy kwasu borowego. Fotoaktywność próbek badano w reakcji degradacji fenolu (Co = 0,21 mmol/dm3 ) w zakresie światła Vis lub UV. Obecność węgla i boru we wszystkich przygotowanych...

INFLUENCE OF TEMPERATURE ON THE ACTIVITY OF ANAMMOX GRANULAR BIOMASS - SHORT AND LONG-TERM ASPECT
PublikacjaThe aim of this study was to determine a short-term and long-term effect of temperature on the anammox process rate and determination of temperature coefficients in the Arrhenius and Ratkowski equations. The short-term effects of temperature on the anammox biomass were investigated in batch tests at ten different temperatures in the range of 10-55 ̊C. The maximum rate 1.3 gN (gVSS·d)-1 observed at 40 ̊C. The minimum rate, close...
