The European Physical Journal E, 2013 The study of systems with sustained energy uptake and dissipation at the scale of the constituent particles is an area of central interest in nonequilibrium statistical physics. Identifying such systems as a distinct category -- Active Matter -- unifies our understanding of autonomous collective move- ment in the living world and in some surprising ...

Physical Review Letters, 2014 We present a general dynamical theory of a membrane coupled to an actin cortex containing polymerizing filaments with active stresses and currents, and demonstrate that active membrane dynamics [Phys. Rev. Lett \textbf{84}, 3494 (2000)] and spontaneous shape oscillations emerge from this description. We also consider membrane instabilities and patterns

Cyclic nucleotide specificity of the activator and catalytic sites of a cGMP-stimulated cGMP phosphodiesterase from Dictyostelium discoideum [PDF]
, 1985 The cellular slime mold Dictyostelium discoideum has an intracellular phosphodiesterase which specifically hydrolyzes cGMP. The enzyme is activated by low cGMP concentrations, and is involved in the reduction of chemoattractant-mediated elevations of ...

Hearing Research, 2020 AbstractThis paper introduces active listening, as a unified framework for synthesising and recognising speech. The notion ofactive listeninginherits from active inference, which considers perception and action under one universal imperative: to maximise the evidence for our (generative) models of the world.

Effect of dsRNA on Mesangial Cell Synthesis of Plasminogen Activator Inhibitor Type 1 and Tissue Plasminogen Activator [PDF]
, 2009 Background/Aims: Viral infections are a major problem worldwide and many of them are complicated by virally induced glomerulonephritides. Progression of kidney disease to renal failure is mainly attributed to the development of renal fibrosis ...

ACE2 ACTIVATION PROMOTES ANTITHROMBOTIC ACTIVITY
The FASEB Journal, 2009 Hyperactivity of the axis ACE/AngII/AT1R of the renin‐angiotensin system is associated with occurrence of acute thrombotic event. Recently a novel concept of a counterrugulatory axis, ACE2/Ang‐(1‐7)/Mas, has emerged. We hypothesized that ACE2 would be protective against thrombosis.
