--- _id: '6140' abstract: - lang: eng text: 'Genome sequence comparisons have highlighted many novel gene families that are conserved across animal phyla but whose biological function is unknown. Here, we functionally characterize a member of one such family, the macoilins. Macoilins are characterized by several highly conserved predicted transmembrane domains towards the N-terminus and by coiled-coil regions C-terminally. They are found throughout Eumetazoa but not in other organisms. Mutants for the single Caenorhabditis elegans macoilin, maco-1, exhibit a constellation of behavioral phenotypes, including defects in aggregation, O2 responses, and swimming. MACO-1 protein is expressed broadly and specifically in the nervous system and localizes to the rough endoplasmic reticulum; it is excluded from dendrites and axons. Apart from subtle synapse defects, nervous system development appears wild-type in maco-1 mutants. However, maco-1 animals are resistant to the cholinesterase inhibitor aldicarb and sensitive to levamisole, suggesting pre-synaptic defects. Using in vivo imaging, we show that macoilin is required to evoke Ca2+ transients, at least in some neurons: in maco-1 mutants the O2-sensing neuron PQR is unable to generate a Ca2+ response to a rise in O2. By genetically disrupting neurotransmission, we show that pre-synaptic input is not necessary for PQR to respond to O2, indicating that the response is mediated by cell-intrinsic sensory transduction and amplification. Disrupting the sodium leak channels NCA-1/NCA-2, or the N-,P/Q,R-type voltage-gated Ca2+ channels, also fails to disrupt Ca2+ responses in the PQR cell body to O2 stimuli. By contrast, mutations in egl-19, which encodes the only Caenorhabditis elegans L-type voltage-gated Ca2+ channel α1 subunit, recapitulate the Ca2+ response defect we see in maco-1 mutants, although we do not see defects in localization of EGL-19. Together, our data suggest that macoilin acts in the ER to regulate assembly or traffic of ion channels or ion channel regulators.' article_number: e1001341 author: - first_name: Fausto full_name: Arellano-Carbajal, Fausto last_name: Arellano-Carbajal - first_name: Luis full_name: Briseño-Roa, Luis last_name: Briseño-Roa - first_name: Africa full_name: Couto, Africa last_name: Couto - first_name: Benny H.

An important question in behavioral ecology asks when is it optimal for an animal to leave a food patch it is depleting. Although optimal foraging is central to evolutionary success, the neural and molecular mechanisms underlying it are poorly understood. Here we investigate the neuronal basis for adaptive food-leaving behavior in response to resource depletion in Caenorhabditis elegans, and identify several of the signaling pathways involved. The ASE neurons, previously implicated in salt chemoattraction, promote food-leaving behavior via a cGMP pathway as food becomes limited. High ambient O2 promotes food-leaving via the O2-sensing neurons AQR, PQR, and URX. Ectopic activation of these neurons using channelrhodopsin is sufficient to induce high food-leaving behavior. In contrast, the neuropeptide receptor NPR-1, which regulates social behavior on food, acts in the ASE neurons, the nociceptive ASH neurons, and in the RMG interneuron to repress food-leaving. Finally, we show that neuroendocrine signaling by TGF-β/DAF-7 and neuronal insulin signaling are necessary for adaptive food-leaving behavior. We suggest that animals integrate information about their nutritional state with ambient oxygen and gustatory stimuli to formulate optimal foraging strategies. author: - first_name: K. full_name: Milward, K. last_name: Milward - first_name: K.

TSG-6-mediated cross-linking ofHA has been proposed as a functional mechanism (e.g.for regu-lating leukocyte adhesion), but direct evidence for cross-linkingis lacking, and we know very little about its impact on HA ultra-structure. Here we used films of polymeric and oligomeric HAchains, end-grafted to a solid support, and a combination ofsurface-sensitive biophysical techniques to quantify the bindingof TSG-6 into HA films and to correlate binding to morpholog-ical changes. We find that full-length TSG-6 binds with pro-nounced positive cooperativity and demonstrate that it cancross-link HA at physiologically relevant concentrations. Ourdata indicate that cooperative binding of full-length TSG-6arises from HA-induced protein oligomerization and that theTSG-6 oligomers act as cross-linkers. In contrast, the HA-bind-ing domain of TSG-6 (the Link module) alone binds withoutpositive cooperativity and weaker than the full-length protein.Both the Link module and full-length TSG-6 condensed andrigidified HA films, and the degree of condensation scaled withthe affinity between the TSG-6 constructs and HA. We proposethat condensation is the result of protein-mediated HA cross-linking. Our findings firmly establish that TSG-6 is a potent HAcross-linking agent and might hence have important implica-tions for the mechanistic understanding of the biological func-tion of TSG-6 (e.g.in inflammation). author: - first_name: Natalia full_name: Baranova, Natalia id: 38661662-F248-11E8-B48F-1D18A9856A87 last_name: Baranova orcid: 0000-0002-3086-9124 - first_name: Erik full_name: Nilebäck, Erik last_name: Nilebäck - first_name: F.

In sorting the motor behavior by the clockwise bias, we find that the distributions of the clockwise (CW) and counterclockwise (CCW) intervals are either exponential or nonexponential with long tails. At low bias, CW intervals are exponentially distributed and CCW intervals exhibit long tails. At intermediate CW bias (0.5) both CW and CCW intervals are mainly exponentially distributed. A simple model suggests that these two distinct switching behaviors are governed by the presence of signaling noise within the chemotaxis network. Low noise yields exponentially distributed intervals, whereas large noise yields nonexponential behavior with long tails. These drastically different motor statistics may play a role in optimizing bacterial behavior for a wide range of environmental conditions. article_processing_charge: No author: - first_name: Heungwon full_name: Park, Heungwon last_name: Park - first_name: Panos full_name: Oikonomou, Panos last_name: Oikonomou - first_name: Calin C full_name: Guet, Calin C id: 47F8433E-F248-11E8-B48F-1D18A9856A87 last_name: Guet orcid: 0000-0001-6220-2052 - first_name: Philippe full_name: Cluzel, Philippe last_name: Cluzel citation: ama: Park H, Oikonomou P, Guet CC, Cluzel P.

Using 57Fe Mössbauer spectroscopy we find that iron in metamict titanite is partitioned between amorphous and crystalline regions based on valence. Trivalent iron exists in the crystalline titanite matrix whereas divalent iron exists almost exclusively in radiation-amorphized regions. We find that the relative abundances of the oxidation states correlate with the volume fraction of amorphous and crystalline regions. Our data also show that oxidation of iron proceeds along with the recrystallization of the amorphized regions. Recrystallization is confirmed to occur over the range 700 °C < T < 925 °C, and no further structural changes are observed at higher temperatures. It is surprising that our Mössbauer measurements show divalent iron to be surrounded by titanite with a high degree of short-range structural order in the amorphized regions. This observation is fundamentally different from other metamict materials such as zircon (ZrSiO4), where amorphized regions show no short-range order. article_number: '105402' article_processing_charge: No article_type: original author: - first_name: E K H full_name: Salje, E K H last_name: Salje - first_name: D J full_name: Safarik, D J last_name: Safarik - first_name: R D full_name: Taylor, R D last_name: Taylor - first_name: M P full_name: Pasternak, M P last_name: Pasternak - first_name: Kimberly A full_name: Modic, Kimberly A id: 13C26AC0-EB69-11E9-87C6-5F3BE6697425 last_name: Modic orcid: 0000-0001-9760-3147 - first_name: L A full_name: Groat, L A last_name: Groat - first_name: J C full_name: Lashley, J C last_name: Lashley citation: ama: 'Salje EKH, Safarik DJ, Taylor RD, et al.

In this article, we demonstrate that by varying the Ag concentration, we can manipulate which variant of the Ag2Te structure stabilizes at room temperature (monoclinic α-Ag2Te or cubic β-Ag1.9Te) and can consequently manipulate the electrical and thermal transport behavior of the composite and hence the thermoelectric performance. Additionally, we show that Cu-doping results in an overall improvement in thermoelectric performance. Our results suggest that formation of composites is a viable path for achieving a phonon-glass-electron-crystal (PGEC) alloy. article_processing_charge: No article_type: original author: - first_name: J. full_name: Capps, J. last_name: Capps - first_name: B. full_name: Ma, B. last_name: Ma - first_name: T. full_name: Drye, T. last_name: Drye - first_name: C. full_name: Nucklos, C. last_name: Nucklos - first_name: S. full_name: Lindsey, S. last_name: Lindsey - first_name: D. full_name: Rhodes, D. last_name: Rhodes - first_name: Q. full_name: Zhang, Q. last_name: Zhang - first_name: Kimberly A full_name: Modic, Kimberly A id: 13C26AC0-EB69-11E9-87C6-5F3BE6697425 last_name: Modic orcid: 0000-0001-9760-3147 - first_name: S. full_name: Cawthorne, S. last_name: Cawthorne - first_name: F. full_name: Drymiotis, F. last_name: Drymiotis citation: ama: Capps J, Ma B, Drye T, et al.

To go beyond the horizon of Li-ion batteries is a formidable challenge; there are few options. Here we consider two: Li–air (O2) and Li–S. The energy that can be stored in Li–air (based on aqueous or non-aqueous electrolytes) and Li–S cells is compared with Li-ion; the operation of the cells is discussed, as are the significant hurdles that will have to be overcome if such batteries are to succeed. Fundamental scientific advances in understanding the reactions occurring in the cells as well as new materials are key to overcoming these obstacles.
