Adverse Outcome Pathways Applied to Space Radiation Research

Environmental and Molecular Mutagenesis, Volume 66, Issue 8, Page 442-462, October 2025.
ABSTRACT Long‐duration spaceflight exposes astronauts to various stressors that can alter human physiology, potentially causing immediate and long‐term health effects. These stressors can damage biomolecules, cells, tissues, and organs, leading to adverse outcomes.

Ocular changes as potential biomarkers for early diagnosis of Alzheimer's disease

Alzheimer's &Dementia, Volume 21, Issue 8, August 2025.
Abstract Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia. AD diagnosis often involves a thorough assessment, including clinical evaluation, cognitive testing, medical history examination, genetic testing, and biomarker analysis. Currently, the invasive nature and high costs of biomarker testing,

Imaging Characteristics of Three Cameras Using the Scheimpflug Principle

Ophthalmic Research, 1990
We studied the handling and the potentials of three different cameras operating according to the Scheimpflug principle and which currently are commercially available. The examinations were performed with the cameras Topcon SL-45, Topcon SL-6E with cataract attachment and Zeiss SLC system.

Extremely asymmetric ectasia: Tomographically unilateral keratoconus

Acta Ophthalmologica, Volume 103, Issue 5, Page 530-538, August 2025.
Abstract Purpose To investigate the characteristics of apparently stable forms of tomographically unilateral keratoconus (KC). Methods In this retrospective case–control study, strict unilaterality criteria were applied to select tomographically unilateral cases with ≥3 years of follow‐up.

Influence of artificial tears on corneal parameter measurement using three different devices: Keratometry and Scheimpflug technology, a randomized trial

Acta Ophthalmologica, Volume 103, Issue 5, Page e310-e317, August 2025.
Abstract Purpose To evaluate the effect of artificial tear (AT) application on the repeatability of corneal parameters with three different devices. Methods In this prospective, randomized clinical trial, 145 patients were measured with one of three devices in the Department of Ophthalmology, Goethe University, Frankfurt, Germany.

Three-dimensional ghost imaging via the Scheimpflug detection

Optics Express
For previous three-dimensional ghost imaging, the acquisition of absolute distance information is mainly based on the principle of time-of-flight, which usually needs lots of measurements and a large detection/modulation bandwidth product. Here we present a technique called three-dimensional ghost imaging via the Scheimpflug detection (3D-GISD), which ...

Analysis of imaging for laser triangulation sensors under Scheimpflug rule

Optics Express, 2013
In this work a detailed analysis of the problem of imaging of objects lying in the plane tilted with respect to the optical axis of the rotationally symmetrical optical system is performed by means of geometrical optics theory. It is shown that the fulfillment of the so called Scheimpflug condition (Scheimpflug rule) does not guarantee the sharp image ...
