A time-based double-sided readout concept of 100 mm LYSO:Ce,Ca fibres for future axial TOF-PET
EJNMMI Physics, 2023 Background Positron emission tomography (PET) requires a high signal-to-noise ratio (SNR) to improve image quality, with time-of-flight (TOF) being an effective way to boost the SNR. However, the scanner sensitivity and resolution must be maintained. The

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Fiber-Based Polarization Diversity Detection for Polarization-Sensitive Optical Coherence Tomography
Photonics, 2014 We present a new fiber-based polarization diversity detection (PDD) scheme for polarization sensitive optical coherence tomography (PSOCT). This implementation uses a new custom miniaturized polarization-maintaining fiber coupler with single mode (SM ...

Imaging Characteristics of the Axicon Imaging System
Proceedings of the 4th International Conference on Photonics, Optics and Laser Technology, 2016 The depth of an image system can be extended by an axicon which can generate line focus. According to physical optical theory, the diffracting patterns of the defocus point spread function (PSF) for the imaging system with axicon are analyzed through the generalize pupil function.

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

TLR5 agonists enhance anti-tumor immunity and overcome resistance to immune checkpoint therapy
Communications Biology, 2023 TLR5 agonists in combination with immune checkpoint therapies (ICT) enhance survival in ICT-refractory murine 4T1 mammary carcinoma and B16-F10 melanoma tumors. Low serum levels of G-CSF and CXCL5 correlate with enhanced survival.

System model of an image stabilization system
SPIE Proceedings, 2014 The Polarimetric and Helioseismic Imager (PHI) instrument is part of the remote instruments for the ESA Solar Orbiter (SO), which is scheduled to launch in 2017. PHI captures polarimetric images from the Sun to better understand our nearest star, the Sun.
