Inter- and intra-individual variability in CO2 production and metabolic rate
Dolaana Khovalyg, Mohamad Rida
Carbon dioxide generated by the human body and exhaled (VCO2) is commonly used for ventilation controls, while the metabolic rate (i.e., energy expenditure EE) is an important parameter defining human thermal comfort in buildings. These two parameters are ...
2023Bacterial colonization in realistic environments: how mechanics impact biofilm formation in the wild and during infection
A variety of physical inputs acts onto bacteria in nature. However, these are most often ignored in the studies of their physiology. There is now increasing evidence indicating that bacteria respond to physical stimuli, including mechanical forces. Yet, qu ...
EPFL2023Comparing end-tidal CO2, respiration volume per time (RVT), and average gray matter signal for mapping cerebrovascular reactivity amplitude and delay with breath-hold task BOLD fMRI
Cerebrovascular reactivity (CVR), defined as the cerebral blood flow response to a vasoactive stimulus, is an imaging biomarker with demonstrated utility in a range of diseases and in typical development and aging processes. A robust and widely implemented ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2023Breathing is coupled with voluntary initiation of mental imagery
Olaf Blanke, Oliver Alan Kannape, Hyeongdong Park
Previous research has suggested that bodily signals from internal organs are associated with diverse cortical and subcortical processes involved in sensory-motor functions, beyond homeostatic reflexes. For instance, a recent study demonstrated that the pre ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2022Gd3+-Functionalized Lithium Niobate Nanoparticles for Dual Multiphoton and Magnetic Resonance Bioimaging
Marinella Mazzanti, Sandrine Gerber, Anne-Sophie Chauvin, Katarzyna Pierzchala, Ileana Ozana Jelescu, Jérémy Vuilleumier, Raphaël Jovita De Matos, Laura Camille Louise Nicolle, Adrian Stefan Gheata, Dario Diviani, Luigi Bonacina, Fiorella Lucarini
Harmonic nanoparticles (HNPs) have emerged as appealing exogenous probes for optical bioimaging due to their distinctive features such as long-term photostability and spectral flexibility, allowing multiphoton excitation in the classical (NIR-I) and extend ...
2022Deep learning architectures for estimating breathing signal and respiratory parameters from speech recordings
Mathew Magimai Doss, Zohreh Mostaani, Venkata Srikanth Nallanthighal
Respiration is an essential and primary mechanism for speech production. We first inhale and then produce speech while exhaling. When we run out of breath, we stop speaking and inhale. Though this process is involuntary, speech production involves a system ...
PERGAMON-ELSEVIER SCIENCE LTD2021Towards an Evolutionary Theory of Stress Responses
All organisms have a stress response system to cope with environmental threats, yet its precise form varies hugely within and across individuals, populations, and species. While the physiological mechanisms are increasingly understood, how stress responses ...
2021Organohalide respiration in Firmicutes: energy metabolism and transcription regulation
Organohalides are a class of compounds often considered as persistent pollutants and harmful to environmental and human health. Some bacteria, among which are representatives from the Firmicutes phylum, are capable of using these compounds as terminal acce ...
EPFL2021Mechanisms of the breathing contribution to bodily self‐consciousness in healthy humans: Lessons from machine‐assisted breathing?
Olaf Blanke, Bruno Herbelin, Oliver Alan Kannape, Elisa Canzoneri, Sophie Jacqueline Andrée Betka
Previous studies investigated bodily self‐consciousness (BSC) by experimentally exposing subjects to multisensory conflicts (i.e., visuo‐tactile, audio‐tactile, visuo‐cardiac) in virtual reality (VR) that involve the participant's torso in a paradigm known ...
Wiley2020Acoustic Resonators for Intracellular Tagging
Cell migration has always been essential for understanding the underlying mechanisms of physiological phenomena. For this reason, many diverse cell tracking methods are presented in literature, such as optical imaging, MRI and radionuclear imaging. However ...
