Continuous‐time digital filtering analogue‐to‐digital converter
Electronics Letters, 2016 Despite their alias‐free operation, continuous time ADCs can have their power consumption overwhelmed when presented out‐of‐band, high frequency, high amplitude signals. A new continuous time ADC architecture which, thanks to its embedded low‐pass filter transfer function is proposed, enables a power efficient quantisation in the presence of such ...

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Molecular Oncology, EarlyView.Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...
