Ultra low frequency yeast cells electric activity
Cifra, Michal ; Pokorný, Jiří ; Jelínek, František ; Hašek, Jiří ; Šimša, Jan
This paper presents results from the measurement of the electrical activity cold sensitive beta-tubulin mutant tub2-401 of yeast cells in frequency region 0.4 - 1.6 kHz. 25 measurements of both synchronized and nonsynchronized cells show that the synchronized cells have higher electrical activity what corresponds to the findings of Pohl et al. Mechanical oscillations of electrically polar structures in cell may give rise to electric oscillations we measured.

Denní změny intenzity emise fotonu z lidských rukou
Cifra, Michal ; Van Wijk, E. ; Koch, H. ; Bosman, S. ; Van Wijk, R.
Spontaneous ultra-weak photon emission in the visible range was measured on palm and dorsal side of left and right hand by means of a low noise photomultiplier system. To study the dynamics of this photon emission in a 24h period photon emission was recorded in 2h intervals in 5 experiments. Mean photon emission over the 24h period differed both between subjects and hand locations. The fluctuations in photon emission in the course of 24h were more at dorsal sides than palm sides.

Lidská spontanní emise fotonu v průběhu 24 hodin
Cifra, Michal ; Van Wijk, E. ; Van Wijk, R.
Ultra-weak spontaneous photon emission in visible range from palms and hands of dark-accommodated subjects has been measured every two hours in 5 experiments in the course of 24 hours by means of low-noise photomultiplier. Dorsal sides of the hands show higher fluctuations of photon emission intensity than palmar sides. Cycles of fluctuations of the 1 day, 6-8 hours and 3-4 hours long period have been observed from Fourier analysis of the measured data.
