Current Biology, 2013 In vertebrates and invertebrates, signaling among neurons is most commonly mediated by chemical synapses. At these synapses neurotransmitter released by presynaptic neurons is detected by receptors on the postsynaptic neurons, leading to an influx of ions through the receptors themselves or through channels activated by intracellular signaling ...

Current Biology, 2009 The central spindle regulates cleavage furrow formation and cytokinesis and is composed of antiparallel microtubules bundled by microtubule-associated proteins and kinesin motors. One key protein in the central spindle is a Rho family GTPase-activating protein, CYK-4/MgcRacGAP, whose target is the subject of two new studies that arrive at divergent ...

Cold Spring Harbor Perspectives in Biology, 2009 Gap junctions are aggregates of intercellular channels that permit direct cell-cell transfer of ions and small molecules. Initially described as low-resistance ion pathways joining excitable cells (nerve and muscle), gap junctions are found joining virtually all cells in solid tissues.

Optimal Gaps in Optimal Paradigms
Catalan Journal of Linguistics, 2005 This article develops a treatment of phonologically motivated gaps in paradigms within Optimal Paradigms Theory (McCarthy 2001). The gaps are instances of absolute ungrammaticality, i.e. situations in which there is no output for a given input.

Normal Anion Gap: A Knowledge Gap
Indian Journal of Critical Care Medicine, 2023 We studied with great interest the article titled "Acute diarrhea and severe dehydration in children: Does non-anion gap component of severe metabolic acidemia need more attention?" by Takia L et al. and would express our views about the same. Normal anion gap metabolic acidosis (NAGMA) is a common entity following stool loss of bicarbonate during an ...

Finance and Economics Discussion Series, 2010 What is the output gap? There are many definitions in the economics literature, all of which have a long history. I discuss three alternatives: the deviation of output from its long-run stochastic trend (i.e., the 'Beveridge-Nelson cycle') the deviation of output from the level consistent with current technologies and ...
