Reduced contribution of the ipsilateral primary motor cortex to force modulation with short-term motor learning in humans: An NIRS study [PDF]

, 2008
How is muscle force modulated during hand exercise? Oxygenation in the contralateral primary motor cortex (M1) has been observed to vary considerably across trials of repetitive handgrip exercise.

Optimal branching asymmetry of hydrodynamic pulsatile trees

, 2010
Most of the studies on optimal transport are done for steady state regime conditions. Yet, there exists numerous examples in living systems where supply tree networks have to deliver products in a limited time due to the pulsatile character of the flow ...

Three-dimensional in vitro cancer spheroid models for Photodynamic Therapy: Strengths and Opportunities

Frontiers in Physics, 2015
Three dimensional, in vitro spheroid cultures offer considerable utility for the development and testing of anticancer photodynamic therapy regimens. More complex than monolayer cultures, three-dimensional spheroid systems replicate many of the important

The effect of epidural dexmedetomidine on oxygenation and shunt fraction in patients undergoing thoracotomy and one lung ventilation: A randomized controlled study

Journal of Anaesthesiology Clinical Pharmacology, 2016
Background and Aims: Role of epidural dexmedetomidine in providing analgesia is well documented, but its effect on oxygenation and shunt fraction is not well established. We studied the hypothesis that epidural dexmedetomidine may improve oxygenation and

Effects of long-term oxygen treatment on α-ketoglutarate dehydrogenase activity and oxidative modifications in mitochondria of the guinea pig heart

European Journal of Medical Research, 2009
Objective Oxygen therapy is used for the treatment of various diseases, but prolonged exposure to high concentrations of O2 is also associated with formation of free radicals and oxidative damage.

Model-Supported Radiotherapy Personalization: In silico Test of Hyper- and Hypo-Fractionation Effects

Frontiers in Physiology, 2018
The need for radiotherapy personalization is now widely recognized, however, it would require considerations not only on the probability of control and survival of the tumor, but also on the possible toxic effects, on the quality of the expected life and
