Unequivocal Cardiac Phase Sorting From Alternating Ramp-And Pulse-Illuminated Microscopy Image Sequences

In vivo microscopy is an important tool to study developing organs such as the heart of the zebrafish embryo but is often limited by slow image frame acquisition speed. While collections of still images of the beating heart at arbitrary phases can be sorte ...

Computational methods for live heart imaging with speed-constrained microscopes

Olivia Mariani

Imaging methods to capture the beating and developing heart inside embryonic animal models such as the zebrafish are a key component for the study of fundamental biological processes such as cardiac birth defects or tissue regeneration. However, live heart ...

Reconstruction of image sequences from ungated and scanning-aberrated laser scanning microscopy images of the beating heart

Michael Stefan Daniel Liebling, Olivia Mariani

Fluorescence laser-scanning microscopy is a well-established imaging technique in biology, available in many imaging facilities to investigate structures within live animal embryos such as zebrafish. Laser scanning microscopes (LSM) are limited when used t ...

Virtual High-Framerate Microscopy of the Beating Heart via Sorting of Still Images

Michael Stefan Daniel Liebling, Olivia Mariani

Microscopy of the beating heart in embryos provides key insights for the study of its development. However, achieving a sufficiently high framerate is difficult with conventional cameras. Here, we present a method to reconstruct an image sequence covering ...

Stressed Mycobacteria Use the Chaperone ClpB to Sequester Irreversibly Oxidized Proteins Asymmetrically Within and Between Cells

Michaël Unser, Olivia Mariani, John McKinney, Neeraj Dhar

Mycobacterium tuberculosis (Mtb) defends itself against host immunity and chemotherapy at several levels, including the repair or degradation of irreversibly oxidized proteins (IOPs). To investigate how Mtb deals with IOPs that can neither be repaired nor ...

Circadian Clock Characteristics Are Altered in Human Thyroid Malignant Nodules

Daniel Sage, Olivia Mariani, Daniel Andreas Schmitter

Context: The circadian clock represents the body's molecular time-keeping system. Recent findings revealed strong changes of clock gene expression in various types of human cancers. Objective: Due to emerging evidence on the connection between the circadia ...
