Factors influencing the adequacy of determining hemispheric language lateralization in presurgical epilepsy patients using functional transcranial Doppler sonography (fTCD).

As the adequacy of determining hemispheric language lateralization (HLL) is of special importance for the planning of epilepsy surgery, this study aimed to identify predictive factors for receiving inconclusive HLL results using functional transcranial Doppler sonography (fTCD). Data from 495 epilepsy patients who received fTCD in a standardized fashion was analyzed retrospectively. HLL was left-sided in 324 patients (65.

Radial matrix constraint influences tissue contraction and promotes maturation of bi-layered skin equivalents.

Human skin equivalents (HSEs) serve as important tools for mechanistic studies with human skin cells, drug discovery, pre-clinical applications in the field of tissue engineering and for skin transplantation on skin defects. Besides the cellular and extracellular matrix (ECM) components used for HSEs, physical constraints applied on the scaffold during HSEs maturation influence tissue organization, functionality, and homogeneity. In this study, we introduce a 3D-printed culture insert that exposes bi-layered HSEs to a static radial constraint through matrix adhesion.

Gastrocnemius medialis contractile behavior during running differs between simulated Lunar and Martian gravities.

The international partnership of space agencies has agreed to proceed forward to the Moon sustainably. Activities on the Lunar surface (0.16 g) will allow crewmembers to advance the exploration skills needed when expanding human presence to Mars (0.

Contractile behavior of the gastrocnemius medialis muscle during running in simulated hypogravity.

Vigorous exercise countermeasures in microgravity can largely attenuate muscular degeneration, albeit the extent of applied loading is key for the extent of muscle wasting. Running on the International Space Station is usually performed with maximum loads of 70% body weight (0.7 g).
