Obituary for Prof. Kazimierz Rzymski

Born on March 13, 1932 in the small town of Nowe Miasto Lubawskie, he was raised during the difficult times of war, hunger and human tragedy. His relentless desire to become a medical doctor and serve humanity succeeded in 1958 when he graduated from Poznań Academy of Medical Sciences (later Poznań University of Medical Sciences, PUMS). From that time on, he worked continuously, both profession...

Fiat lux

Just as engineers learnt to harness the power of electrons in transistors and microchips—which revolutionized modern society—physicists and biologists are now learning how to tame photons. Their work is generating exciting new possibilities for optical microscopy, with a resolution and level of detail hitherto undreamt of. Biophotonics is a new and exciting research field that is already delive...

Detection of DNA damage by use of Escherichia coli carrying recA'::lux, uvrA'::lux, or alkA'::lux reporter plasmids.

Plasmids were constructed in which DNA damage-inducible promoters recA, uvrA, and alkA from Escherichia coli were fused to the Vibrio fischeri luxCDABE operon. Introduction of these plasmids into E. coli allowed the detection of a dose-dependent response to DNA-damaging agents, such as mitomycin and UV irradiation. Bioluminescence was measured in real time over extended periods. The fusion of t...

Modelling of the Impact of Ear Implants to Ear Acoustics

Modelowanie wpływu implantów usznych na akustykę ucha S t r e s z c z e n i e W artykule przedstawiono metodykę tworzenia modelu ucha ludzkiego dla symulacji numerycznej stopnia oddziaływania wprowadzanych implantów usznych na jego akustykę metodą elementów skończonych. Wyszczególniono główne jego zmienne geometryczne umożliwiające dopasowanie modelu do indywidualnych cech anatomicznych układu ...
