This study was aimed to optimize the extraction process for Salvia miltiorrhiza Bunge polysaccharide using response surface methodology The results showed that four operating parameters including microwave power, microwave time and the particle size had notable effects on the polysaccharide extraction of Salvia miltiorrhiza Bunge. The effects could be ranked in decreasing order of importance as...

Obituary of insight into the mechanisms of myelination and of In Memoriam: neuronal–glial interactions. Wood, Dick established that the axon was mitogenic for Schwann cells and oligodendrocytes (Wood and Bunge, 1975, 1986), providing the first example of the biological The neuroscience community has lost a pioneer, a men-activity we now recognize as the neuregulin family of tor, and a generous ...

Flavonoids from Trollius chinensis Bunge.(Flos Trollii) were extracted by different method were investigated in the present study. Simultaneous determination of two flavonoids(orientin and vitexin) was accomplished by a useful, rapid and simple HPLC/DAD-ESI-MS method. A central composite design (CCD) combined with response surface methodology(RSM) was used to study the effects of extraction tim...

A reference extractive, containing multiple active known compounds, has been considered to be an alternative to individual reference standards. However, in the Chinese Pharmacopoeia (ChP) the great majority of reference extractives have been primarily used for qualitative identification by thin-layer chromatography (TLC) and few studies on the applicability of reference extractives for quantita...

This report concerns a case with unusual lesions consisting of massive destruction of myelinated fibres in a thin marginal layer at the surface of the spinal cord, brain-stem, optic nerve and tract, without involvement of the superficial portions of grey matter. The lesions showed a striking similarity to those produced by barbotage (aspiration and reinjection of cerebrospinal fluid) in experim...

Das Bunge-Wand-Weber-Modell wurde in der Literatur bereits angewendet, um Modellierungssprachen wie das Entity-Relationship-Model oder die Unified Modeling Language zu evaluieren. In diesem Beitrag wird aufbauend auf dem Bunge-Wand-Weber-Modell eine Methode zur Evaluierung von Referenzmodellen eingeführt. Zentrales Konzept dieser Methode ist die ontologische Normalisierung eines Referenzmodells...
