Defective flow space limits the scaling up of turbulence bioreactors for platelet generation

Communications Engineering
To complement donor-dependent platelets supplies, we previously developed an ex vivo manufacturing system using induced pluripotent stem cell (iPSC)-derived expandable immortalized megakaryocyte progenitor cell lines (imMKCLs), and a turbulent flow ...

Numerical simulation of turbulent flow between shrouded contra-rotating disks

Advances in Mechanical Engineering, 2016
The turbulent flow between shrouded contra-rotating disks was numerically studied with a two-layer turbulence model and a modified Launder–Sharma low-Reynolds number k - ε model.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

FEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Turbulent Heat Transfer over roughness: a comprehensive review of theories and turbulent flow structure

International Journal of Thermofluids
Turbulent heat transfer over rough surfaces is crucial in natural and industrial processes, yet it has received less attention than that of momentum transfer.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

On the influence of a large scale coherent vortex on the turbulent cascade [PDF]

Nonlinear Processes in Geophysics, 1996
We investigate the flow between coaxial rotating disks in the situation where a strong axial vortex is present over a turbulent background. This is nonstationary and inhomogeneous as is common in most turbulent geophysical flows.

Generalized self-similar spectrum and the effect of large-scale in decaying homogeneous isotropic turbulence

New Journal of Physics, 2018
In statistically stationary conditions, the turbulent energy spectrum in a high Reynolds number flow exhibits a k ^−5/3 (Kolmogorov) regime, with a faster decay at larger, dissipative wavenumbers.
