Structure and Function Analysis of a Plant Transcription Activator
… One such cis-element, activation sequence (as)-1 (-83 to -63) mediates preferential expression in root. The element contains a tandem repeat of the motif TGACG, that is crucial for as-1 function and binding of a tobacco nuclear factor, activation sequence factor (ASF)-1. Two other …

Etablierung und Anwendung der Chromatin-Immunopräzipitation für <i>in vivo</i>-Bindungsstudien der bZIP-Transkriptionsfaktoren TGA2.1 und TGA2.2 an Promotoren der Pathogenabwehr in Tabak
Das as-1-Element, welches ursprünglich aus dem Blumenkohl-Mosaik-Virus isoliert wurde, ist induzierbar durch Salizylsäure (SA), Auxin und Pathogenbefall. Elemente, die dem as-1-Element ähnlich sind, wurden in Promotoren vieler Pathogenabwehr-Gene gefunden. Zu ihnen zählen z.B. das früh exprimierte …

Die Bedeutung des Proteins Scarecrow-like 14 in der Regulation der Transkription von Stressgenen
Das cis-regulatorische Element as-1 ist durch Salizylsäure (SA) und Auxin induzierbar. Dabei wird eine Beteiligung von reaktiven Sauerstoffspezies (ROS) vermutet. Transkriptionsfaktoren der TGA-Familie binden an das as-1-Element und führen so zu einer Aktivierung der Genexpression. Für TGA2.2 aus …

Spin-squeezing of ⁸⁷Rb via optical measurement
This project aims to reduce measurement uncertainty in atomic clocks by squeezing the collective spin of atoms. Spin-squeezing reduces noise below the standard quantum limit where precision scales as 1/ [square root of] N, allowing us to instead approach the Heisenberg limit where it scales as 1/N. …

DNA chip designed antisense oligodeoxynucleotides targeting EGFR MRNA for brain tumour therapy
Glioblastoma multiforme (GBM) is a malignant brain tumour for which there is currently no effective treatment regime. It is thought to develop due to the overexpression of a number of genes, including the epidermal growth factor receptor (EGFR), which is found in over 40% of GBM. Novel forms of …

The closed form error expression with Parseval's theorem
… form error expression of optimum Wiener filter was first introduced by M. C. Yovit and J. L. Jackson in 1955. Since then, a number of people have proved the validity of this form using almost similar technique but no one has succeeded to extend the Yovit-Jackson's original formula for the other …

Rhizophoraceae alkaloids : studies in the synthesis of Gerrardine
Gerrardine, an alkaloid isolated from Cassipourea gerrardii was previously established as 1-methyl-2,5-bis( 4'-hydroxy-1',2'-dithiolan-3'-yl)-pyrrolidine. The aim of the present research was to study the ways in which 1-methyl-2-(4'-hydroxy-1', 2'-dithiolan-3'-yl)-pyrrolidine, as a model compound …
