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.

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...

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...

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...
