Chiral Capillary Electrophoresis in Current Pharmaceutical and Biomedical Analysis


Book Description

The scientific monograph by the author Peter Mikus entitled "Chiral Capillary Electrophoresis in Current Pharmaceutical and Biomedical Analysis" provides a comprehensive view on the advanced capillary electrophoresis techniques aimed to current chiral bioanalysis. The advances in the chiral electrophoresis analytical approaches are divided and theoretically described in three sections involving (i) advanced chiral separations for the optimization of chiral resolution (separation mechanisms; electrophoresis techniques in capillary and microchip format; electrophoretic modes such as ITP, CZE/EKC, CEC; chiral additives / pseudophases / phases), (ii) advanced sample preparation for the on-line preconcentration, sample clean-up and analyte derivatization (implementation of electrophoretic effects such as stacking; non-electrophoretic effects such as SPE, chromatography, dialysis; combinations of these effects; multidimensional CE systems; instrumental schemes), (iii) advanced combinations of detection and electrophoresis for the optimization in qualitative and quantitative evaluation (the most important universal as well as selective detection approaches such as absorption and fluorescence spectrophotometry, electrochemical detection, mass spectrometry vs. (i) and/or (ii)). Real analytical potential (benefits and limitations) of these advanced analytical approaches is emphasized by selected performance parameters of the methods and illustrated by many current practical applications including chiral analyses of drugs, their (bio)degradation products and biomarkers in pharmaceutical and biological matrices. The author wishes the readers many inspirations in the creation of new innovative approaches in the field of advanced chiral electrophoresis techniques with the aim to overcome capabilities of the current analytical techniques.

Structure/Function Analysis of the Amino-Terminal Domain of the Androgen Receptor


Book Description

"This is a Ph.D. dissertation. The amino-terminal domain (NTD) of the androgen receptor (AR) is indispensable for AR transactivation and contains a strong activation function 1. Its activity is affected by coregulators that influence a number of functional properties of AR. The NTD of the AR is 529 aa long and is a complex domain with several functions, namely p160 recruitment, interaction with the LBD, and it contains two transactivation functions Tau-1 And Tau-5. The aim of this study was to obtain a more detailed structure-function analysis of the NTD of the AR. Contents include: Introduction, N/C Interaction in AR-mediated Transactivation, Polyglutamine Stretch, SUMOylation of the AR, Activation Function of the hAR, Discussion, Summary and conclusions, Future Prospects."







Ligand and Electronically Induced Activation Patterns in Myenteric Neuronal Networks


Book Description

Gastrointestinal motility regulated by hormonal, myogenic and neuronal mechanisms. The neuronal control consists of two elements: on the one hand the extrinsic innervation by para- and ortho-sympathetic nerve fibres and on the other hand intrinsic intrinsic innervation by the enteric nervous system (ENS). The myenteric plexus as part of the ENS, is to a great extent involved in the control of gastrointestinal motility. The guinea-pig myenteric plexus has been the subject of intense research over the last three decades, resulting in a better understanding of gastrointestinal physiology and motility. The ENS comprises a large diversity of neurons. Current classification schemes of enteric neurons are mainly based on the data obtained from classical electrophysical experiments, immunohistochemistry and retrograde labeling techniques. Electrophysiological recordings give real-time information concerning the electrical activity of one impaled myenteric neuron (S/AH type neurons), but this information is mostly limited to a single neuron. Immunohistochemical staining for different neurotransmitters or different functionally relevant proteins provides information about an activity due to intrinsic technical limitations of fixation techniques.
