TL;DR: The possibility that taurine participates as an osmoeffector in astrocytes was examined in cultured Astrocytes exposed to hyposmolar conditions.
Abstract: Astrocytes in culture regulate their volume under anisosmotic conditions by as yet unclear mechanisms. In a number of other cells this process involves a loss of intracellular osmotically active solutes, including taurine. The possibility that taurine participates as an osmoeffector in astrocytes was examined in cultured astrocytes exposed to hyposmolar conditions. Astrocytes responded to decreases in osmolarity by rapid swelling followed by a volume regulatory phase. Hyposmotic conditions induced a dramatic increase of 3H-taurine efflux, with a time course corresponding to the cell volume regulatory phase. Decreasing osmolarity from 310 to 254, 198 or 150 m osmoles resulted in the release of 8.2%, 17%, and 54%, respectively, of 3H-taurine previously accumulated by astrocytes. Endogenous taurine concentration decreased 64%. The efflux of 3-H GABA, 3H-glycine, or 3H-D-aspartate was much less affected under similar conditions. These results suggest a role for taurine as an osmoeffector in astrocytes.

TL;DR: A new Klebsiella species, K. variicola, is proposed on the basis of total DNA-DNA hybridization, on the monophyly observed in the phylogenetic analysis derived from the sequences of rpoB, gyrA, mdh, infB, phoE and nifH genes and on distinct phenotypic traits.

TL;DR: A very fast deconvolution method, which is based on the fast Fourier transform, can be used to control the outputs from a multichannel plant comprising any number of control sources and error sensors, resulting in a matrix of causal finite impulse response filters whose performance is optimized at a large number of discrete frequencies.
Abstract: A very fast deconvolution method, which is based on the fast Fourier transform (FFT), can be used to control the outputs from a multichannel plant comprising any number of control sources and error sensors. The result is a matrix of causal finite impulse response filters whose performance is optimized at a large number of discrete frequencies. The paper is particularly aimed at multichannel sound reproduction and more specifically reproducing the sound field from a set of loudspeakers.

TL;DR: In this paper, the authors show that the relatively random spiking times of individual neurons are a source of noise in the brain and that in a finite-sized cortical attractor network, this can be an advantage, for it leads to probabilistic behavior that is advantageous in decision-making, by preventing deadlock, and is important in signal detectability.
