Probing minimal SUSY scenarios in the light of muon g−2g-2 and dark matter

We study supersymmetric (SUSY) models in which the muon $g-2$ discrepancy and the dark matter relic abundance are simultaneously explained. The muon $g-2$ discrepancy, or a 3$\sigma$ deviation between the experimental and theoretical results of the muon anomalous magnetic moment, can be resolved by SUSY models, which implies at least three SUSY multiplets have masses of $\mathop{\mathcal{O}}(100)\, \mathrm{GeV}$. In particular, models with the bino, higgsino and slepton having $\mathop{\mathcal{O}}(100)\, \mathrm{GeV}$ masses are not only capable to explain the muon $g-2$ discrepancy but naturally contains the neutralino dark matter with the observed relic abundance. We study constraints and future prospects of such models; in particular, we find that the LHC search for events with two hadronic taus and missing transverse momentum can probe this scenario through chargino/neutralino production. It is shown that almost all the parameter space of the scenario can be probed at the high-luminosity LHC, and a large part can also be tested at the XENON1T experiment as well as at the ILC.Comment: 16 pages, 5 figures; the published versio

Integral presentation of Experimental Results and Bioinformatic Analyses on _Ciona_ _intestinalis_ Proteins

For the aim of facilitating biologists to find new knowledge through the comprehensive proteomic and transcriptomic data of _Ciona intestinalis_, we have been developing an intuitive and integral view of experimental and bioinformatic results for each protein, which, unlike on human proteins, was incomplete for _Ciona_ proteins. In the presentation, we integrated in a view the experimental results of 2D-PAGE analyses done at Shimoda Marine Research Center, University of Tsukuba, 3D-view of expressions (3DPL) done by Hotta _et al_., and cross-references with JGI version 1 and ENSEMBL. A total of 1,673 entries of 2D-PAGE and 57 of 3DPL are currently contained in CIPRO database. The information is summarized in a single page for a protein. Together with BLAST results, comparative genomics, expression profiles, domain search results, localization, phylogeny etc., we provide biologists the highly integrated view amongst the existing databases, which facilitates to understand the protein. For example, the 2D-PAGE and the microarray results of the same protein are sometimes different, which implies the spatial or temporal gaps of the expressions between the mRNA and the protein. Besides, two functionalities are implemented. One is an improved 2D-PAGE viewer, which provides the compact view of spots and experimental information, and another is peptide fragment mass search functionality as improved PerMS algorithm by Hozumi _et al_., by enabling detection of seven kinds of modifications and suspected contaminants

Incorporating Community Annotation Interfaces into the CIPRO2.5 Database with Comprehensible Sketches to Support Quick Annotations of Proteome Data.

User annotation or comment interfaces are now widely used in several web sites such as journals, news, weblogs and Wikipedia. However, there are only a few biological databases with annotation interfaces. The _Ciona_ _intestinalis_ protein database (CIPRO) was created in order to provide integrated proteome data especially for experimental biologists. The current database contains 89,673 unique sequences covering all the known and predicted gene models. Typical tasks include which gene models are reliable and which function is plausible. The human-curated annotation is most important for the meaningful database.
Here we incorporate three new functions into the CIPRO2.5 database (http://cipro.ibio.jp/2.5/), providing enriched resources for the users. First, a community annotation interface as web forms and a user comment editor with rating its comment were added. Second, the web pages were specifically designed to compact for quickly understood overviews. For example, cytolocalization was automatically provided by a color-depicted cell image based on the intensity instead of the numeric values of raw data. The expression data of EST, microarray and 2D-PAGE were integrated as one chart. In addition to these data, the images of transmembrane prediction, domain and motif search, and the OMIM ortholog on the chromosome map were included in each protein page. The last, even the BLAST and PMF search were added to combined fields in the retrieval system.
As a result, a total of 11,134 pages were annotated by our community. Furthermore, 2,186 comments were added to the database. Those annotated data are freely accessible at the CIPRO2.5 web site

Possible co-option of engrailed during brachiopod and mollusc shell development

In molluscs, two homeobox genes, engrailed (en) and distal-less (dlx), are transcription factors that are expressed in correlation with shell development. They are expressed in the regions between shell-forming and non-shell-forming cells, likely defining the boundaries of shell-forming fields. Here we investigate the expression of two transcription factors in the brachiopod Lingula anatina. We find that en is expressed in larval mantle lobes, whereas dlx is expressed in larval tentacles. We also demonstrate that the embryonic shell marker mantle peroxidase (mpox) is specifically expressed in mantle lobes. Our results suggest that en and mpox are possibly involved in brachiopod embryonic shell development. We discuss the evolutionary developmental origin of lophotrochozoan biomineralization through independent gene co-option

Left-right asymmetric expression of dpp in the mantle of gastropods correlates with asymmetric shell coiling

Background: Various shapes of gastropod shells have evolved ever since the Cambrian. Although theoretical analyses of morphogenesis exist, the molecular basis of shell development remains unclear. We compared expression patterns of the decapentaplegic (dpp) gene in the shell gland and mantle tissues at various developmental stages between coiled-shell and non-coiled-shell gastropods. Results: We analyzed the expression patterns of dpp for the two limpets Patella vulgata and Nipponacmea fuscoviridis, and for the dextral wild-type and sinistral mutant lineage of the pond snail Lymnaea stagnalis. The limpets had symmetric expression patterns of dpp throughout ontogeny, whereas in the pond snail, the results indicated asymmetric and mirror image patterns between the dextral and sinistral lineages. Conclusion: We hypothesize that Dpp induces mantle expansion, and the presence of a left/right asymmetric gradient of the Dpp protein causes the formation of a coiled shell. Our results provide a molecular explanation for shell, coiling including new insights into expression patterns in post-embryonic development, which should aid in understanding how various shell shapes are formed and have evolved in the gastropods.ArticleEVODEVO. 4:15 (2013)journal articl

Severe accidental colchicine poisoning by the autumn crocus: A case of successful treatment

AbstractBackgroundThe common garden plant autumn crocus contains colchicine and its derivatives. Colchicine poisoning causes abdominal cramps and diarrhea within hours. Several days later, multiorgan failure, pancytopenia, and cardiovascular collapse occur.1,2 Severe colchicine poisoning is associated with high mortality.Case reportA 63-year-old woman who accidentally ingested an autumn crocus, which contained ∼0.38 mg colchicine, had severe vomiting and was taken to an emergency center. She presented with symptoms of gastroenterocolitis within 1 hour of ingestion, and bone marrow hypoplasia with pancytopenia developed on the 3rd day after ingestion. We continued administration of granulocyte colony-stimulating factor (300 μg) for 5 days until we confirmed that the patient's white blood cell count was increasing. Also, there was focal and segmental intestinal ischemia and some cakes of charcoal remained in the intestinal tract. Therefore, we presumed that nonocclusive mesenteric ischemia was caused by hypotension with severe dehydration, although pseudo-obstruction due to the activated charcoal may have been a contributing factor. We were able to promptly intervene to treat paralytic ileus and gastrointestinal edema before anticipated worsening of abdominal compartment syndrome, by conducting open peritoneal drainage. Despite severe poisoning, our patient survived with intensive care. Conclusion: Colchicine intoxication may lead to a sudden and extreme critical course. Therefore, as there is no means to predict prognosis from initial severity of symptoms at onset, we suggest that all patients suspected of colchicine intoxication should be managed in hospital with continuous vital sign monitoring and frequent laboratory testing for at least a few days after ingestion
