Our recent lab studies and visits to other labs
Visit to NTNU Trondheim, Norway (September 2010)
In September 2010, Dr. Darija Bakovic Kramaric spent ten days in the laboratory of Dr. Amundsen’s from the Department of Circulation and the Medical Imaging from the Norwegian University of Science and Technology, Trondheim, Norway. This visit was mainly supported by travel grant from the Unity through Knowledge Fund awarded to researcher. The main goal of the visit was learning the base of tissue velocity imaging, tissue tracking and tissue synchronization imaging with the emphasis on various training procedures relevant for the evaluation of different cardiologic diseased states in humans. She also became familiar more with the technical part of the ultrasound devices. Importantly, during the stay in Trondheim, the applicant had a chance to conduct intense discussions with his colleagues, as well as meet a number of other colleague scientists that work in the similar research area, that also opened possibilities for new joint projects and additional educational visits and exchange of know-how.
Visit to Neurovascular Research Lab, UWO, Canada (November 2009)
During the period of November 8th till December 2nd our PhD student Toni Breskovic was visiting Neurovascular Research Laboratory (NVRL) at University of Western Ontario, London, Canada. This was his second visit to this group.
The primary goal of the visit was learning advanced type of analysis of muscle sympathetic activity (MSNA) recordings. More specifically, the analysis included use of wavelet denoising in raw MSNA data analysis. This approach in analysis further improves interpretation of the MSNA recordings. The methodology was used for the first time to analyze the data recorded during our previous joint study.
Parallel with that, Dr. Breskovic participated in one pilot study performing microneurography technique. In the pilot protocol a lower body negative pressure chamber (LBNP) was used. Therefore, Dr. Breskovic was better familiarized with the use of it, since LBNP represents one of elementary techniques for testing and stimulating sympathetic neural activity.
All visit objectives were successfully satisfied, fostering more intensive collaboration between our two groups in the future.
Joint study between our Department and Neurovascular Research Lab (UWO, Canada), Split, Croatia (June 2009)
Craig D. Steinback M.Sc., a PhD student from Neurovascular Research Laboratory at University of Western Ontario, London, Canada, was a guest in our lab in June 2009.
The purpose of his visit was to perform a joint study with apnea divers. Apnea divers represent an interesting physiological model for testing central and peripheral chemoreflex sensitivity, arterial blood chemistry, patterns of sympathetic activation during long maximal apneas, baroreflex sensitivity etc.
This comprehensive study included technique of microneurography for recording muscle sympathetic neural activity (MSNA), arterial line placement for invasive blood pressure recording and blood gasses analysis. Protocol consisted of couple of rebreathing maneuvers and several repeated end-expiratory, end-inspiratory and end-inspiratory apneas with glossopharyngeal insufflation maneuvers (air-packing).
The study was completed successfully, providing more than enough of interesting data to be published as part of Mr. Steinback’s and Dr. Breskovic’s PhD theses.
Visit to NTNU Trondheim, Norway (December 2008)
In November/December 2008, a two of our young faculty, Drs. Jasna Marinovic and Marko Ljubkovic spent a month in the laboratory of Dr. Ulrik Wisloff from the Department of Circulation and the Medical Imaging from the Norwegian University of Science and Technology, Trondheim. This visit was mainly supported by two travel grants from the Unity through Knowledge Fund awarded to each researcher. The main goal of the visit was learning the technique of generation the animal model of heart failure and the procedures required for assessment of cardiac function in operated animals. Moreover, Drs. Marinovic and Ljubkovic observed the laboratory procedures and protocols of exercise training of the experimental animals. The main idea behind the visit is to introduce the described model at their domicile institution, since the cardioprotective mechanisms and procedures that may be employed to improve the performance of the diseased myocardium has been one of Jasna’s and Marko’s main research interests. Some of the results of their previous work were also presented at the International conference of Exercise in Medicine organized in Trondheim during their stay at Dr. Wisloff’s lab, which also provided an excellent opportunity for discussion with eminent experts from the field and open the possibility for further collaborations.
