Exposure of a small Arctic seabird, the little auk (Alle alle) breeding in Svalbard, to selected elements throughout the course of a year
PublikacjaThe Arctic marine ecosystem can be altered by processes of natural and anthropogenic origin. Spatio-temporal variation in species exposure to contamination is still poorly understood. Here, we studied elemental concentrations in the non-lethally collected samples from the most numerous seabird in European Arctic, the little auk (Alle alle) nesting in one breeding colony in Svalbard. This seabird spent the breeding season in the...

Time-Gating method with automatic calibration for accurate measurements of electrically small antenna radiation patterns in Non-Anechoic environments
PublikacjaNon-anechoic sites represent a cheap alternative to measurements of antennas in dedicated facilities. However, due to a high noise—from the external EM signal sources and multipath interferences—the quality of radiation patterns obtained in non-anechoic conditions is poor. The characteristics can be corrected using a time-gating method (TGM), which involves filtering of the noise based on temporal analysis of the measured signals....

Cell-penetrating peptides – mechanism of transduction and synthesis – short review
PublikacjaPotential antimicrobial agents may be effective if they are delivered efficiently to their site of action. In many cases, lack of permeability through the cell membrane is the main problem. One of the possible solutions could be a novel intracellular delivery system involving cell-penetrating peptides (CPPs), which may improve the efficiency of many new biophar-maceuticals. Among other things, CPPs are capable of trans-porting...
