New sequence data resources allow the investigation of physiologically important processes in spotlight evolution to an unprecedented level detail. Outward-rectifying Kout channels and TPC1 – cation predominantly involved electrical signalling angiosperms have remained largely conserved during land plant evolution. Inward-rectifying potassium segregated into different subclades seed plants, aft...

We study ribbons of vanishing Gaussian curvature, i.e., flat ribbons, constructed along a curve in $\mathbb{R}^{3}$. In particular, we first investigate to which extent the ruled structure determines ribbon: other words, ask whether for given $\gamma$ and ruling angle (angle between line curve's tangent) there exists well-defined ribbon. It turns out that answer is positive only up an initial c...

the focus of this paper lies on abu ali farsi's general views on the development of linguistic phenomena including synonymity, antonymity, parallelism, lexical assimilation, and metathesis. the paper sheds light on the views erroneously attributed to abu ali farsi, somehow analyzing and rectifying misinterpretations given to his views.

It has been shown previously that the muscarinic cholinergic system in the nucleus raphe magnus (NRM) is involved in the modulation of nociception. In this study, we examined the direct actions of muscarine on the NRM neurons in a slice preparation. Muscarine (1-30 microM) produced a dose-dependent hyperpolarization in a subpopulation of the NRM cells that contain 5-hydroxytryptamine (5-HT). In...

Sensory transduction in the cochlea depends on regulated ion secretion and absorption. Results of whole-organ experiments suggested that Reissner's membrane may play a role in the control of luminal Cl(-). We tested for the presence of Cl(-) transport pathways in isolated mouse Reissner's membrane using whole-cell patch clamp recording and gene transcript analyses using RT-PCR. The current-volt...
