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 (Costellaria) scitulum
No full textVexillum (Costellaria) scitulum (A. ADAMS, 1853) Mitra chariessa MELVILLL, 1888 syn. nov. In Turner (2001) Mitra chariessa MELVILLL, 1888 (Fig. 8) was synonymized with Vexillum (C.) rubellum (ADAMS & REEVE, 1850) (Figs 9–10), but when comparing the type species in NMW with the new species, the authors realized that M. chariessa should be synonymized with Vexillum (C.) scitulum (A. ADAMS, 1853) instead. The type of M. chariessa and the syntypes of V. (C.) scitulum have the same slender appearance, an identical cancellated surface with a more prominent second spiral cord below the suture and the same colouration. The holotype of M. chariessa and the larger syntype of V. (C.) scitulum are nearly completely faded, but on close examination, slightly brown faded dots can be seen on the periphery of the body whorl of both shells. This characteristic can be better seen on the smaller syntype in the NHMUK. In contrast, V. (C.) rubellum differ from the mentioned types. This species is larger, the axial ribs are thicker and, as mentioned by Adams & Reeve (1850) in the original description, V. (C.) rubellum has more swollen whorls and the longer siphonal canal is significantly recurved.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 64, DOI: 10.5169/seals-787039, http://zenodo.org/record/584621
Relation between examinees’ true knowledge and examination scores: systematic review and exemplary calculations on Pick-N items
No full textThis manuscript focusing on Pick-N items is the second of two manuscripts regarding scoring approaches of two specific multiple-select item types commonly used to assess knowledge in written examinations. In contrast to other multiple-select item types, the number of true answer options to be marked within each Pick-N item is disclosed to examinees. As various scoring methods for Pick-N items exist, the present study aimed to help educators make informed choices about the use of Pick-N items, the scoring method to be selected, and related aspects (i.e. defining appropriate examination pass marks). Available scoring methods for conventional multiple-select items and Pick-N items were systematically identified from the literature. Their statistical parameters were compared by assessing the metrics available information included and expected chance scores from random guessing. The study further aimed to examine the relation between examinees' true knowledge and expected scoring results when using Pick-N items
