Looking for PhD student: mathematical modeling

We have opened competition for a PhD student position: Mathematical modeling of energy transfer and mechanics in theheart In heart muscle cells, energy used by most of the processes in the muscle cells is supplied in the form ofATP by mitochondria. Within this project, you would be designing state-of-the-art mathematical models to unravel mechanisms regulating ATP production in mitochondria, selection of energy transfer pathways between mitochondria and ATP consumers, as well as working o...

Student team project: Software for protein determination

We are looking for a student team working on proteomics gel analysis software. The software is expected to take as an input gel description and photo images containing gel measurements. As an output, software should calculate image intensities in regions that the user can interactively select. The algorithms for that will be provided but need to be implemented by the student team. Example gel image with the marked regions of interest for analysis Software will be released as a cross-platf...

Looking for PhD student

We have opened competition for a PhD student position: Tracking molecular movement to unravel diffusion barriers in cardiac cells This is an interdisciplinary project combining physics and biology to study the intracellular environment in the heart muscle. Through the development of cutting-edge experimental and data analysis approaches, it is expected to reveal intracellular environment properties that govern molecular movements and shape its physiology. So that the heart could produc...

Summer job for students

We are looking for a B.Sc. or M.Sc. student to work full or part-time during the summer and, if there is an interest, for longer. The job is to do Western blots to assess whether the phosphorylation status of some proteins is different in hearts from creatine-deficient mice. Image analysis and insertion into the database is also part of the job. The results can stand alone and form the basis for a thesis. It is an advantage to have experience with laboratory work, but we will be happy to ...

Looking for PhD students

We have opened competition for two PhD student positions: Linking energetics to muscle phenotype: the importance of intracellular microdomains on the regulation of AMP-activated kinase . The aim of this project is to study in detail how energetics affects the signaling pathways in skeletal and heart muscle tissue. You will learn how to combine experimental and theoretical approaches to extract as much information as possible from your data.Deep dive into the cardiac cell: tracking molecular ...

Altered calcium handling in cardiomyocytes from arginine-glycine amidinotransferase-knockout mice is rescued by creatine

Martin Laasmaa, Jelena Branovets, Karina Barsunova, Niina Karro, Craig A Lygate, Rikke Birkedal, Marko Vendelin Am J Physiol Heart Circ Physiol. 2021 Feb 1;320(2):H805-H825 PMID: 33275525DOI: 10.1152/ajpheart.00300.2020 Abstract The creatine kinase system facilitates energy transfer between mitochondria and the major ATPases in the heart. Creatine-deficient mice, which lack arginine-glycine amidinotransferase (AGAT) to synthesize creatine and homoarginine, exhibit reduced cardiac co...

Cardiac expression and location of hexokinase changes in a mouse model of pure creatine deficiency

Jelena Branovets, Niina Karro, Karina Barsunova, Martin Laasmaa, Craig A Lygate, Marko Vendelin, Rikke Birkedal Am J Physiol Heart Circ Physiol. 2021 Feb 1;320(2):H613-H629 PMID: 33337958DOI: 10.1152/ajpheart.00188.2020 Abstract Creatine kinase (CK) is considered the main phosphotransfer system in the heart, important for overcoming diffusion restrictions and regulating mitochondrial respiration. It is substrate limited in creatine-deficient mice lacking l-arginine:glycine amidinotr...

IOCBIO Kinetics: An open-source software solution for analysis of data traces

Marko Vendelin, Martin Laasmaa, Mari Kalda, Jelena Branovets, Niina Karro, Karina Barsunova, Rikke Birkedal PLoS Comput Biol. 2020 Dec 22;16(12):e1008475. PMID: 33351800PMCID: PMC7787677DOI: 10.1371/journal.pcbi.1008475 Abstract Biological measurements frequently involve measuring parameters as a function of time, space, or frequency. Later, during the analysis phase of the study, the researcher splits the recorded data trace into smaller sections, analyzes each section separately b...
