Neurodegenerative and neuroinflammatory disorders often involve complex pathophysiological mechanisms that are â to this date â only partially understood. A more comprehensive understanding of those microstructural processes and their characterization ...
in vivo bioluminescence imaging (BLi) is an optical molecular imaging technique used to visualize molecular and cellular processes in health and diseases and to follow the fate of cells with high sensitivity using luciferase-based gene reporters. The high ...
Bioluminescent imaging is a powerful technique that enables imaging in living organisms with high sensitivity, low background signal, low cost and without the need for radioactivity. The emitted photons are produced in the oxidation reaction of luciferin c ...
Studying biological processes on the level of live cells with the help of biocompatible reac-tions has tremendously advanced our understanding of basic biology. However, the great complexity of many human pathologies such as cancer, diabetes and neurodegen ...
Bioorthogonal chemistry has developed significant over the past few decades, to the particular benefit of molecular imaging. Bioluminescence imaging (BLI) along with other imaging modalities have significantly benefitted from this chemistry. Here, we revie ...
Increasing interest in understanding fundamental biological processes, among which aging and nutrition, has led to the study of simple and powerful model organisms, as the round-worm Caenorhabditis elegans (C. elegans). The nematode, selected by Sydney Bre ...

Molecular medical imaging is intended to increase the accuracy of diagnosis, particularly in cardiovascular and cancer-related diseases, where early detection could significantly increase the treatment success rate. In this study, we present mixed micelles ...
Molecular imaging allows noninvasive visualization of biological processes in their native environment within living systems. It can give a better understanding of fundamental biology, help in identifying disease mechanisms and visualizing pathological tis ...
Proprotein Convertases (PCs) constitute a family of serine proteases that activate various
hormones, growth factors and cell adhesion molecules by mediating endoproteolytic cleavage
of their secreted inactive precursors during their transit in the secret ...
