Modeling Regulation of Zinc Uptake via ZIP Transporters in Yeast and Plant Roots [PDF]
In yeast (Saccharomyces cerevisiae) and plant roots (Arabidopsis thaliana) zinc enters the cells via influx transporters of the ZIP family. Since zinc is both essential for cell function and toxic at high concentrations, tight regulation is essential for

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 ...

Efficient Prodrug Activator Gene Therapy by Retroviral Replicating Vectors Prolongs Survival in an Immune-Competent Intracerebral Glioma Model. [PDF]
Prodrug activator gene therapy mediated by murine leukemia virus (MLV)-based retroviral replicating vectors (RRV) was previously shown to be highly effective in killing glioma cells both in culture and in vivo.

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

Nerve cell differentiation in hydra requires two signals [PDF]
Endogenous signals controlling nerve cell commitment in hydra were investigated using an assay for committed nerve precursors. Extracts of hydra tissue were prepared and tested for their ability to induce nerve cell commitment.

Cyclic nucleotide specificity of the activator and catalytic sites of a cGMP-stimulated cGMP phosphodiesterase from Dictyostelium discoideum [PDF]
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 ...

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.

ACE2 ACTIVATION PROMOTES ANTITHROMBOTIC ACTIVITY
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.
