In Vitro Kavapyrone Production and Genomic Stability of in Vitro Kava Cultures
Inter simple sequence repeat (ISSR) markers were used for detection of polymorphism among in vitro kava cultures. An absence of normally observed bands was observed among organogenic callus cultures, while a small degree of ISSR polymorphism was detected among regenerated plantlets.

Frakturverhalten verschiedener Wurzelstiftsysteme in vitro
In order to reach sufficient retention of restorations on endodontically treated teeth and in order to stabilize the remaining tooth structure various post systems can be inserted in the root canal. This study compares a titanium post system to a ceramic and a fibre-reinforced composite post system …

Modelling Human Glomerulosclerosis in vitro
… and mesangial cells (MCs), and dysregulation in the interaction between these cell types results in glomerulosclerosis. This is characterised by excessive extracellular matrix deposition and cell dysfunction leading to disproportionate MC proliferation and POD loss. Animal models of …

In-vitro Clot Formation and Failure
A primary cause of bleeding and mortality after traumatic injury is failure of hemostatic clot formation at wound sites. After trauma, approximately 25-30% of severe injured patients display trauma induced coagulopathy (TIC) which is a multifactorial condition that causes poor clot formation and …

In vitro inhibition of coronavirus replications
"In Vitro Inhibition of Coronavirus Replications A search for new anti-coronaviral drugs to treat coronaviral infections was motivated by an outbreak of severe acute respiratory syndrome (SARS). In order to find drugs that treat coronavirus infections, including SARS, we screened traditional …

In vitro Kavitationsuntersuchungen an mechanischen Herzklappenprothesen
… of impairment still represents a major task. In this dissertation -in continuation of the studies of Graf et al. -several investigations of cavitation, in particular of "severe" vapor cavitation, were conducted in order to describe the phenomenon of cavitation itself and to classify various …

Vergleichende In-vitro-Testung von Kavafiltern
PURPOSE: In vitro evaluation of six established and two new IVC Filters in order to compare their capture rates.MATERIAL AND METHODS: Six established IVC Filters, the already in vitro tested Cook Celect Filter and a newly developed mesh Filter had to pass several tests in a flow model where they …

Model for tooth development in vitro
The ultimate goal of Tissue Engineering is the regeneration of whole organs or functional organ units. Recent approaches rely on the usage of adult tissue-specific cells in three-dimensional culture. It is now accepted that "Developmental Engineering", the recapitulation of critical initial steps …

In vitro model of periodontal epithelium
To develop a model for junctional epithelium, porcine periodontal ligament epithelial cells (PLE cells) were cultured from the epithelial rests of Malassez. The obtained epithelial cell lines were grown on a porous membrane that allows a good cell adhesion and access of the nutrients from both …

Biochemistry of ovarian cells in vitro
The major roles of prostaglandins of the E and F series in reproductive processes are reviewed,, The structures and bio¬ synthesis of the prostaglandins are described before discussing how prostaglandins may be involved in ovulation, luteal regression and uterine physiology in primates and …

Protein Engineering via in Vitro Coevolution
The creation of novel protein functions represents a significant challenge in protein engineering. To address this challenge, I have developed a simple and efficient method---in vitro coevolution---for the creation of novel protein functions in an existing protein scaffold. The in vitro coevolution …

In Vitro Cultivation of Anaplasma Marginale
Virulent Anaplasma marginale propagated in culture of bovine erythrocytes showed an increasing rate of replication in a sequence of three experiments. The changes in percentage of parasitized erythrocytes (PPE) were monitored by Giemsa staining and the organism was identified by the direct …

Analysis of neural circuits in vitro
This thesis is a collection of manuscripts addressing connectivity of neural circuits in cultured hippocampal neurons. These studies begin with an investigation of dopaminergic modulation of excitatory synapses in small circuits of neurons grown on glial micro islands. We found that dopamine …
