Zellteilungsregulation meristematischer Wurzelzellen (Tabak BY-2) durch Phytohormone und Zucker
… wurden mit einer Tabak Zellkultur (BY-2) durchgeführt, die als Modell eines Wurzelmeristems dienen sollte. Ein Vorteil dieser Zellkultur ist die Möglichkeit, den Zellzyklus der Zellen durch auswaschbare Hemmstoffe synchronisieren zu können. Diese Synchronisierung eröffnet die …

TUNING 2-BY-2 MULTI-LOOP PI CONTROLLERS USING RELAY FEEDBACK
… plants in the process industry are controlled by placing controllers of the Proportional plus Integral (PI) structure or the Proportional plus Integral plus Derivative (PID) structure in a multi-loop fashion. This thesis aims to provide some insights into how multi-loop PI controllers in a …

The Evolution of Enzymatic Activity in the Crotonase Superfamily: The Mechanism of the Reaction Catalyzed by 2-Ketocyclohexanecarboxyl-Coa Hydrolase
… progress of the reaction catalyzed by BadI is important for understanding the catalytic roles of residues in the active site. It was concluded that, unlike other stereochemically characterized crotonase homologs, this reaction must proceed via a Z-enolate. Based on the information …

The preparation of heterocycles by [2+2+2] cyclization and inverse electron demand Dels-Alder reactions of arynes with 1,2,4-triazines
Transition metal mediated [2 + 2 + 2] cyclizations have been well researched over the past several years. As a well-developed methodology, [2 + 2 + 2] chemistry has been employed as a major pathway to various carbo- and heterocyclic synthetic targets. Numerous transition metals have been applied as …

Einsatz von Pflanzenzellkulturen als industriell nutzbare Expressionssysteme für therapeutische Proteine
Within the present thesis transgenic BY-2 cultures should be tested regarding their potential as industrial expression system for therapeutic proteins. For this purpose, BY-2 cultures expressing recombinant HSA under control of the CaMV 35SS promoter were developed. A leader peptide ensured the …

Pflanzenzellen als Produktionssystem zur Gewinnung von Interleukin-4 Doppelmutein (IL-4 DM)
… and in tobacco suspension cells of the cultivar BY-2, making it possible to compare two fundamentally different plant production platforms. In order to increase the level of protein expression, the IL-4 DM gene sequence was optimised for plant cells; by drawing on PCR technology, synthetic …

Membrane Domain of Plant 3-Hydroxy-3-Methylglutaryl Coenzyme A Reductase: Targeting, Topology, and Function
… step in isoprenoid biosynthesis is catalyzed by 3-hydroxy-3-methylglutaryl CoA reductase (HMGR, EC 1.1.1.34). In plants, HMGR is encoded by small gene families whose members are differentially expressed. In tomato, hmg2 was previously isolated and sequenced. We report the isolation and …

Processing resources, cautiousness, memory self -efficacy, and age differences in free recall
… manipulations were based on a 2 (sex) by 2 (processing speed) by 2 (cautiousness) by 2 (working memory) mixed design. Cautiousness was manipulated by monetary incentive and punishment. Age-related reduction in working memory capacity was simulated by using a the concurrent digit load …

Banded matrices with banded inverses
… matrix. We consider mainly the two factor 2-by- 2 block matrix and the three factor 2-by-2 block matrix cases. We prove that the ranks of the blocks in the larger banded matrix need to necessarily conform to a particular order. We show that for other orders, the banded matrix in question may …

Expression and characterisation of biopharmaceuticals in heterologous expression systems
… anti-HIV full-size IgG1/kappa antibody, (BY-2)2F5, and a soluble form of the high-affinity receptor for human IgG, Fc-gamma-RI (CD64), were successfully established and optimised for heterologous expression in plants, bacteria and mammalian. The first aim of this thesis was the …

The Evaluation of Company-Sponsored Test-Preparation Courses: Training Different Aged Employees on General Test-Taking Skills and Basic Cognitive Skills
… decline has not been accompanied consistently by lower job performance. Subsequently, factors external to the test are being more closely examined for their effects on test performance. Two such factors, a lack of general test-taking skills and a reduced level of basic cognitive skills, are …

Stochastic stability of replicator dynamics with random jumps
… and their e ffects on the fi tness. Assuming a 2 by 2 game and using a particular characteristic of the jump functions we are able to estimate the ergodic measure for all games. Lastly, working with results and methods developed by Imhoff, we prove some stability theorems for an arbitrary n by n …
