Science often grows exponentially from certain key insights, and the insight Marvin Minsky
had in 1955 is no exception. While working as a postdoctoral fellow at HarvardUniversity,
Minsky sought a method to reduce the high level of light scatter that made high contrast imag‐
ing of thick specimens impossible by standard light microscopy.

Ever since the invention of laser by Schawlow and Townes in 1958, various innovative ideas of laser-based applications emerge very year. At the same time, scientists and engineers keep on improving laser's power density, size, and cost which patch up the gap between theories and implementations. More importantly, our everyday life is changed and influenced by lasers even though we may not be fully aware of its existence.
Non-invasive Breslow index determination would allow one-time procedure for melanoma
clinical management which would be of utmost medical interest for several reasons:
unimpaired sentinel lymph node status, low morbidity, pain and stress associated to
surgical excision margins. However, as explained throughout the current chapter, such a
determination requires melanoma diagnosis prior to Breslow determination.

Our goal is to develop automated methods for the segmentation of threedimensional
biomedical images. Here, we describe the segmentation of confocal
microscopy images of bee brains (20 individuals) by registration to one
or several atlas images. Registration is performed by a highly parallel implementation
of an entropy-based nonrigid registration algorithm using B-spline
transformations. We present and evaluate different methods to solve the correspondence
problem in atlas based registration.
In 1665, a book was published that inaugurated the use of the microscope to
investigate the natural world. The author was Robert Hooke, a talented artist,
architect, and amateur scientist. Hooke wrote Micrographia: Or Some
Physiological Descriptions of Minute Bodies Made by Magnifying Glasses with
Observations and Inquiries Thereupon, at the behest of the newly chartered
Royal Society in London, for whom he was working as curator of scientific
experiments. In Micrographia, he presented the first detailed observations of
everyday objects made with his self-constructed light microscope....
We analyzed the role of gangliosides in the association of the ErbB2 recep-tor tyrosine-kinase (RTK) with lipid rafts in mammary epithelial HC11
cells. Scanning confocal microscopy experiments revealed a strict ErbB2–
GM3 colocalization in wild-type cells. In addition, analysis of membrane
fractions obtained using a linear sucrose gradient showed that ErbB2, epi-

Jurkat T lymphocytes were treated with daunorubicin and
WP631, a daunorubicin-based DNAbinding agent, in
experiments aimed to analyze cellular uptake of these drugs
and their effect on cell viability. WP631 was taken up more
slowly than daunorubicin, but laser confocal microscopy
and spectrofluorometricquantificationshowed that thedrug
accumulated in the cells. Despite the slow uptake rate, the
antiproliferative capacity of WP631 (measured as IC50after
a 72-h continuous treatment) was greater than that of

Inducible nitric oxide synthase (iNOS) functions as a homodimer. In cell
extracts, iNOS molecules partition both in cytosolic and particulate frac-tions, indicating that iNOS exists as soluble and membrane associated
forms. In this study, iNOS features were investigated in human intestinal
epithelial cells stimulated with cytokines and in duodenum from mice
exposed to flagellin. Our experiments indicate that iNOS is mainly associ-ated with the particulate fraction of cell extracts.
The relationships between cardiac cell structure and the regulation of
mitochondrial respiration were studied by applying fluorescent confocal
microscopy and analysing the kinetics of mitochondrial ADP-stimulated
respiration, during calcium-induced contraction in permeabilized cardiomyo-cytes and myocardial fibers, and in their ‘ghost’ preparations (after selective
In the eight years since publication of the first edition, enormous progress has been
made in the field of skin imaging and analysis. Because of the broad array of new
methods now available to the research scientist—and more and more to the clinically-
oriented dermatologist—we were able to widen the scope of this book from
the skin surface to the entire skin. This is also reflected in the change of the volume
title, Bioengineering of the Skin: Skin Imaging and Analysis.
Hence, this second edition is a major revision of the first edition, with more
than 30 new chapters added....
TRPM4b is a Ca
-activated, voltage-dependent monovalent cation chan-nel that has been shown to act as a negative regulator of Ca
to be involved in the generation of oscillations of Ca
influx in Jurkat
T-lymphocytes. Transient overexpression of TRPM4b as an enhanced
green fluorescence fusion protein in human embryonic kidney (HEK) cells
resulted in its localization in the plasma membrane, as demonstrated by
confocal fluorescence microscopy.
The uptake by mammalian cells of phosphorothioate oli-gonucleotides was compared with that of their respective
complexes or conjugates with cationic, cell-penetrating
model peptides of varying helix-forming propensity and
amphipathicity. An HPLC-based protocol for the synthesis
and purification of disulfide bridged conjugates in the 10–
100 nmol range was developed. Confocal laser scanning
microscopy (CLSM) in combination with gel-capillary
electrophoresis and laser induced fluorescence detection
(GCE-LIF) revealed cytoplasmic and nuclear accumula-tion in all cases. ...
