A natural deep eutectic solvent - protonated L-proline-xylitol - based stationary phase for gas chromatography
PublicationThe paper presents a new kind of stationary phase for gas chromatography based on deep eutectic solvents (DES) in the form of a mixture of L-proline (protonated with hydrochloric acid) as a hydrogen bond acceptor (HBA) and xylitol as a hydrogen bond donor (HBD) in a molar ratio of HBA:HBD 5:1. DES immobilized on a silanized chromatographic support was tested by gas chromatography (GC) in order to determine its resolving power for...

Izoenzymy cytochromu P450 w metabolizmie związków endo- i egzogennych.
PublicationCytochromy P450 (CYP) należą do enzymatycznych białek hemowych występujących we wszystkich organizmach żywych. W komórkach eukariotycznych katalizują biosyntezę związków endogennych, głównie lipidów i ich pochodnych, ale także metabolizm ksenobiotyków, w tym leków. W reakcjach tych substraty ulegają C-oksydacji (hydroksylacja, epoksydacja, peroksydacja), N-oksydacji, S-oksydacji oraz oksydacyjnej O-, S-, i N-dealkilacji. W konsekwencji...

SHEAR YIELD STRESSES AND FRACTURE TOUGHNESS OF SCOTS PINE (PINUS SYLVESTRIS L.) ACCORDING TO THE RAW MATERIAL PROVENANCE
PublicationIn this paper values of the fracture toughness and of shear yield stress in the shear zone of Scots pine are presented. Tests of cutting were carried on samples of Scotch pine (Pinus sylvestris L.) wood of five provenances from Poland. These experimentally cutting tests were carried on the sash gang saw PRW-15M and the values of cutting power were obtained. The values of fracture toughness and shear yield stress based on Atkins’s...

l-ascorbic acid modified poly(ester urethane)s as a suitable candidates for soft tissue engineering applications
PublicationIn this paper we created novel poly(ester urethane)s (PESUs) designed specifically for tissue engineering. The PESUs were derived from oligomeric α,ω-dihydroxy(ethylene-butylene adipate) (dHEBA), 1,4-butanediol (BDO) and aliphatic 1,6-hexamethylene diisocyanate (HDI) and modified with l-ascorbic acid to improve their biocompatibility. In addition, we determined their mechanical properties (such as tensile strength, elongation at...
