For comparative purposes, important diagnostic features of <i>Zorotypus medoensis</i> from the type locality are figured (Fig. 6). Both <i>Z</i>. <i>medoensis</i> and <i>Z</i>. <i>sinensis</i> lack a strongly elongate and coiled flagellum, indicating that these two species may be more closely related to <i>Z</i>. <i>ceylonicus</i> Silverstri from Sri Lanka (Hwang 1974: 427) than to the southeastern Asian and central American species that share this structure (see ‘Comparative diagnosis’ of <i>Z</i>. <i>hainanensis</i> sp. n. above, and Mashimo et al. 2013: 512).</p>Published as part of <i>Yin, Zi-Wei, Li, Li-Zhen & Wu, Chao, 2015, New and little known species of Zorotypus Silvestri (Zoraptera: Zorotypidae) from China, pp. 557-566 in Zootaxa 4007 (4)</i> on page 565, DOI: 10.11646/zootaxa.4007.4.6, <a href="http://zenodo.org/record/240040">http://zenodo.org/record/240040</a>

Collecting method and dates: The 9 known specimens were collected using light traps or UV lighting between the end of June and end of August. We do not assign this new species to any of the species groups created by Miller (1951; 1955) for the Old World fauna of Reduvius or the senilis group that was created by Wygodzinsky and Usinger (1964) for the Nearctic endemics. The new species shares several diagnostic species group features with species in the senilis group, among them the size, general coloration, the short first metatarsomere, and a median abdominal carina. In addition, the distinct lateral process on the basal plate extension is shared with some of the endemic Nearctic species. However, the median process of the pygophore is rather uniformly low and broad, and has distinct lateral processes in the three species of the senilis group, whereas this process has a narrow base and apical triangular rami in R. frommeri. A final diagnostic feature of the group, the fact that the parameres are visible in situ, is also lacking in R. frommeri. This may either indicate that R. frommeri is not closely related to the three other Nearctic endemics, or that the diagnosis of the senilis group should be revisited. A comprehensive taxonomic revision that integrates morphological, molecular, phylogenetic, and geographic data is clearly overdue for this large genus and species group concepts should be tested as part of this effort. We would typically advise against adding a new species to a genus that is likely not monophyletic and in need of a taxonomic revision. However, this new species is morphologically distinct from other sympatric species, geographically disjunct from the great majority of congeners, and restricted to fairly remote desert areas of Southern California, making it very unlikely that this species is adventive and conspecific with any of the described Old World taxa. We also hope that description of this new species will raise awareness and result in the eventual collection of additional specimens. Lastly, this contribution demonstrates that species discovery even for conspicuous organisms that typically have large distribution range in a fairly well-studied part of the world is not complete.Published as part of Weirauch, Christiane, Russell, Kaleigh & Hwang, Wei Song, 2015, Reduvius frommeri, a new species of Reduviidae from the Western United States (Hemiptera: Reduviidae), with a synopsis of the Nearctic species of Reduvius Fabricius, pp. 267-279 in Zootaxa 3972 (2) on pages 269-277, DOI: 10.11646/zootaxa.3972.2.7, http://zenodo.org/record/23953
Duality between N=5 and N=6 Chern-Simons matter theory
No full textWe provide evidences for the duality between N = 6 U(M)(4) x U(N)(-4) Chern-Simons matter theory and N = 5 O((M) over cap)(2) x U Sp(2 (N) over cap)(-1) theory for a suitable (M) over cap, (N) over cap by working out the superconformal index, which shows perfect matching. For N = 5 theories, we show that supersymmetry is enhanced to N = 6 by explicitly constructing monopole operators filling in SO(6)(R) R-currents. Finally we work out the large N index of O(2N)(2k) x U Sp(2N)(-k) and show that it exactly matches with the gravity index on AdS(4) x S-7/D-k, which further provides additional evidence for the duality between the N = 5 and N = 6 theory for k = 1.open1155sciescopu
Electrophysiological Study on the Effects of Leptin in Rat Dorsal Motor Nucleus of the Vagus
No full textImmunoreactivity of leptin receptor (Ob-R) has been detected in rat dorsal motor nucleus of the vagus (DMNV). Here, we confirmed the presence of Ob-R immunoreactivity on retrograde-labeled parasympathetic preganglionic neurons in the DMNV of neonatal rats. The present study investigated the effects of leptin on DMNV neurons, including parasympathetic preganglionic neurons, by using whole cell patch-clamp recording technique in brain stem slices of neonatal rats. Leptin (30-300 nM) induced membrane depolarization and hyperpolarization, respectively, in 14 and 15 out of 80 DMNV neurons tested. Both leptin-induced inward and outward currents persisted in the presence of TTX , indicating that leptin affected DNMV neurons postsynapticafly. The current-voltage (I-V) curve of leptin- induced inward currents is characterized by negative slope conductance and has an average reversal potential of -90 +/- 3 mV. The reversal potential of the leptin-induced inward current was shifted to a more positive potential level in a high-potassium medium. These results indicate that a decrease in potassium conductance is likely the main ionic mechanism underlying the leptin-induced depolarization. On the other hand, the I-V curve of leptin-induced outward currents is characterized by positive slope conductance and has an average reversal potential of -88 +/- 3 mV, suggesting that an increase in potassium conductance may underlie leptin-induced hyperpolarization. Most of the leptin-responsive DMNV neurons were identified as being parasympathetic preganglionic neurons. These results suggest that the DMNV is one of the central target sites of leptin, and leptin can regulate parasympathetic outflow from the DMNV by directly acting on the parasympathetic preganglionic neurons of the DMNV
Crystal structure of the Ate1 arginyl-tRNA-protein transferase and arginylation of N-degron substrates
No full text
N-degron pathways are proteolytic systems that target proteins bearing N-terminal (Nt) degradation signals (degrons) called N-degrons. Nt-Arg of a protein is among Nt-residues that can be recognized as destabilizing ones by the Arg/N-degron pathway. A proteolytic cleavage of a protein can generate Arg at the N terminus of a resulting C-terminal (Ct) fragment either directly or after Nt-arginylation of that Ct-fragment by the Ate1 arginyl-tRNA-protein transferase (R-transferase), which uses Arg-tRNA
Arg
as a cosubstrate. Ate1 can Nt-arginylate Nt-Asp, Nt-Glu, and oxidized Nt-Cys* (Cys-sulfinate or Cys-sulfonate) of proteins or short peptides.
Ate1
genes of fungi, animals, and plants have been cloned decades ago, but a three-dimensional structure of Ate1 remained unknown. A detailed mechanism of arginylation is unknown as well. We describe here the crystal structure of the Ate1 R-transferase from the budding yeast
Kluyveromyces lactis
. The 58-kDa R-transferase comprises two domains that recognize, together, an acidic Nt-residue of an acceptor substrate, the Arg residue of Arg-tRNA
Arg
, and a 3′-proximal segment of the tRNA
Arg
moiety. The enzyme’s active site is located, at least in part, between the two domains. In vitro and in vivo arginylation assays with site-directed Ate1 mutants that were suggested by structural results yielded inferences about specific binding sites of Ate1. We also analyzed the inhibition of Nt-arginylation activity of Ate1 by hemin (Fe
3+
-heme), and found that hemin induced the previously undescribed disulfide-mediated oligomerization of Ate1. Together, these results advance the understanding of R-transferase and the Arg/N-degron pathway.

Effects of Mindfulness-Based Positive Behavior Support (MBPBS) Training Are Equally Beneficial for Mothers and Their Children With Autism Spectrum Disorder or With Intellectual Disabilities
Get PDFParenting a child with autism spectrum disorder (ASD) or intellectual disabilities (IDs) can be stressful for many parents. Mindfulness-Based Positive Behavior Support (MBPBS) is a customized mindfulness program that enables parents and other caregivers to reduce their perceived psychological stress to normative levels through mindfulness procedures and to support children with ASD or ID to self-manage their challenging behaviors through positive behavior support (PBS). In this study, we evaluated whether MBPBS would have differential effects on the stress levels of mothers of adolescents with ASD (n = 47) or with ID (n = 45) and the effects of the program on the aggressive, disruptive, and compliance behaviors of their children. Both groups of mothers participated in the 40-week study (10 weeks control and 30 weeks MBPBS program), rated their own stress levels, and collected daily observational data on the adolescents’ behavior. Results showed significant reductions in the level of stress in both groups of mothers, but no differential effects on mothers of children with ASD or with ID. In addition, significant reductions in aggression and disruptive behavior and increases in compliance behaviors were observed in the adolescents in both groups. The results suggest that MBPBS is equally beneficial for mothers of adolescents with ASD or ID. In the present study, although the mothers of children with ID had slightly higher levels of stress at baseline and mothers of children with ASD had lower levels of stress following the MBPBS program, the program can be considered equally effective in reducing the stress levels of both groups of mothers. This suggests that the program may be effective regardless of baseline levels of mothers’ stress
