Vexillum RoDING 1798
No full textGenus: Vexillum RöDING, 1798 Type species: By subsequent designation (Woodring 1928): Vexillum plicatum RöDING, 1798 = Voluta plicaria LINNAEUS, 1758 = Vexillum (Vexillum) plicarium (LINNAEUS, 1758).Published as part of Herrmann, Manfred & Salisbury, Richard, 2012, A new species of Vexillum (Costellaria) (Gastropoda: Costellariidae) from the Marquesas with remarks on Mitra chariessa MELVILL, 1888, pp. 57-66 in Contributions to Natural History 24 on page 58, DOI: 10.5169/seals-787039, http://zenodo.org/record/584621
Brain derived proteins as markers of acute stroke: Their relation to pathophysiology, outcome prediction and neuroprotective drug monitoring
No full textPurpose: Ischemic stroke is associated with a variety pathophysiological changes affecting both glial and neuronal brain tissue. These changes are mirrored in the release of specific proteins into peripheral blood. Neurone-specific enolase (NSE), protein S100B and glial fibrillary acidic protein (GFAP) are those proteins investigated most often as peripheral surrogate markers of brain damage after stroke in humans. Methods and results: In the present article we present data which show that the release patterns of neuronal and glial tissue derived proteins after acute stroke are associated with the neuroradiological and neurobehavioral consequences of ischemic brain lesions and. additionally, may be useful in short-term outcome prediction. Kinetics of protein serum concentrations, however, are highly dependent on subtype of stroke lesions and do not merely reflect the degree of brain damage. They rather express complex neuronal-glial interactions as a (patho-)physiological consequence of ischemic brain lesions. We further demonstrate that S100B release patterns do reflect successful neuroprotective drug treatment with recombinant human erythropoietin (EPO) in acute stroke patients. Conclusions: The analysis of poststroke serum concentrations of glial tissue derived proteins might be a promising strategy to monitor and evaluate neuroprotective approaches in stroke treatment

Vexillum (Protoelongata) xerampelina Herrmann & Stossier & Salisbury 2014, comb. nov.
No full textVexillum (Protoelongata) xerampelina (MELVILL, 1895) comb. nov. (Figs 3, 40–41) Description Broad, cylindraceous shell with elongated spire, shiny, reaching about 20 mm in length. Teleoconch consists of 8 to 10 slightly convex whorls. Spire outline straight to slightly concave, 16 to 18 regularly positioned axial ribs on all whorls, sometimes flattened on dorsal side of body whorl, spiral striae on the whole shell. Suture well defined, slightly undulated. Aperture shorter than half the entire shell, lirate inside. Lip straight in posterior half, then recurved towards the siphonal fasciole. Siphonal canal short and slightly recurved. Columella with 4 strong folds, decreasing in size anteriorly and merging into spiral cords on the siphonal fasciole. Colour pattern: Shell dark red to orange. Protoconch and first whorls sometimes darker, columellar folds greyish, columellar shield and aperture shell coloured. Holotype: NMW.1955.158.00429 (coll. Melvill-Tomlin), ex coll. E.R. Shopland; J.C. Melvill; 18.8 mm. Type locality: Arabian Sea, Yemen, Aden. Distribution: From the Red Sea (Gulf of Aqaba) in the north (Wils & Verbinnen 2002) via the Arabian Sea (Melvill 1895) and Mozambique to Réunion in the south (Robin & Martin 2004). The species is also reported from the western Pacific: Japan (Okutani 2000), Philippines (Schepmann 1911 – Figs 42–43) and Guam. Further investigation is necessary to prove whether those specimens also belong to this species or to a closely related one. Remarks: This species was often put into synonymy with Vexillum (Protoelongata) corallinum (REEVE, 1845) comb. nov. (Okutani 2000) or Vexillum (Pusia) semicostatum (ANTON, 1838) (Turner 1989, 1997, 2001; Wils & Verbinnen 2002), but is easy to distinguish from those species by the missing white dots.Published as part of Herrmann, Manfred, Stossier, Günter & Salisbury, Richard, 2014, A new subgenus including three new species of the genus Vexillum (Gastropoda: Costellariidae) from the central Indo-Pacific with remarks on Vexillum (Pusia) semicostatum (ANTON, 1838), pp. 1-55 in Contributions to Natural History 24 on page 17, DOI: 10.5169/seals-787038, http://zenodo.org/record/584611
