System for measurement of concentration of intracellular calcium in LabVIEW
Kormanovskaya, Elena ; Kolářová, Jana (referee) ; Čmiel, Vratislav (advisor)
The master’s thesis deals with the methods and system for measurement of concentration of intracellular calcium in LabVIEW. The thesis included theoretical and practical parts. The thesis covers the theory of fluorescence principles, fluorescence methods and indicators for measurement of concentration of intracellular calcium. The procedure of measurement by means of fluorescence microscope, camera and indicators is also mentioned. Literary solution is presented. Block diagram of system for measurement of concentration of intracellular calcium at a graphical programming environment LabVIEW is presented in practical part of master’s thesis.

Intracellular Calcium Measurement Methods
Číhal, Martin ; Ronzhina, Marina (referee) ; Čmiel, Vratislav (advisor)
This work aims to focus on the issue of intracellular calcium. Not only the theory dealing with the history of fluorescent indicators but also the types of fluorescent indicators and methods of measurements are summarized. The individual steps of measurements on the fluorescent microscope are mentioned as well. There is also created a program for evaluting Ca2+ concentrations in cells made in matlab.

Calcium homeostasis and modulation of nociceptive synaptic transmission
Sojka, David
This study was designed to improve our knowledge regarding mechanisms of nociceptive signaling at spinal cord level. One of the forms of spinal cord synaptic transmission modulation is central sensitization, a manifestation of synaptic plasticity at spinal cord level, which was found to be present at many chronic pain syndromes. This study deals mainly with a development of calcium imaging technique with a final goal to study mechanisms of central sensitization in vitro on population of dorsal horn neurons. We have analyzed synaptically evoked intracellular Ca changes as a result of dorsal root stimulation in a superficial dorsal horn area in spinal cord slices and found two types of Ca responses: one synchronized with electrical stimulation and a second one, delayed response due to Ca release from internal stores. The delayed Ca release was not previously shown to be present in these neurons and it was not dependent on activation of ionotropic glutamatergic receptors, suggesting involvement of metabotropic receptor pathway. The presence of this delayed type of Ca response could have a significant role in the induction of some types of chronic pain syndromes, since intracellular calcium increase is thought to be a key trigger point in spinal cord neurons sensitization. An important role in neuronal calcium...
