Cold stress-induced autophagy and apoptosis disorders are mainly mediated by AMPK/PPAR/PI3K/AKT/mTOR pathways
Under cold stress, the processes of autophagy, apoptosis and energy metabolism are pivotal for sustaining energy and tissue balance. However, the molecular regulatory mechanisms and interactions underlying these processes are still largely unknown. In this ...
Amsterdam2024Targeting TDP-43 Proteinopathies in Neurodegeneration by its Native-State Stabilization.
Preventing the misfolding or aggregation of TDP-43 is the most actively pursued disease-modifying strategy to treat amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases. In our work, we provide proof of concept that native state stabili ...
EPFL2024Diagenetic isotope exchange in biocalcites for paleoclimate reconstruction
Deyanira Graciela Cisneros Lazaro
The oxygen isotope compositions of fossil biocalcites, such as foraminifera, bivalves, brachiopods, and belemnites have allowed for reconstructions of sea surface and deep ocean temperatures throughout the Phanerozoic and constitute the most important reco ...
EPFL2024A compact approach to higher-resolution resonant inelastic x-ray scattering detection using photoelectrons
Henrik Moodysson Rønnow, Markus Scholz
The detection of inelastically scattered soft x-rays with high energy resolution usually requires large grating spectrometers. Recently, photoelectron spectrometry for analysis of x-rays (PAX) has been rediscovered for modern spectroscopy experiments at sy ...
Iop Publishing Ltd2024A continuous-wave and pulsed X-band electron spin resonance spectrometer operating in ultra-high vacuum for the study of low dimensional spin ensembles
Giovanni Boero, Fabio Donati, Soyoung Oh
We report the development of a continuous-wave and pulsed X-band electron spin resonance (ESR) spectrometer for the study of spins on ordered surfaces down to cryogenic temperatures. The spectrometer operates in ultra-high vacuum and utilizes a half-wavele ...
Aip Publishing2024Ghost imaging using two SPAD array detectors: a parameter study towards the realization of a 3D quantum microscope
Edoardo Charbon, Claudio Bruschini, Paul Mos, Yang Lin
Quantum ghost imaging can be an important tool in making optical measurements. One of the most useful aspects of ghost imaging is the unique ability to correlate two sets of independently collected information. We aim to use the principles of ghost imaging ...
Spie-Int Soc Optical Engineering2024The CRL5-SPSB3 ubiquitin ligase targets nuclear cGAS for degradation
Andrea Ablasser, Baptiste Claude André Guey, Jonathan Jean-Pierre Ricci, Chong Liu, Pauline Ambre Melenec, Pengbiao Xu, Lingyun Li, Ying Liu
Cyclic GMP-AMP synthase (cGAS) senses aberrant DNA during infection, cancer and inflammatory disease, and initiates potent innate immune responses through the synthesis of 2 ' 3 '-cyclic GMP-AMP (cGAMP)1-7. The indiscriminate activity of cGAS towards DNA d ...
Nature Portfolio2024Controlling crystal cleavage in focused ion beam shaped specimens for surface spectroscopy
Philip Johannes Walter Moll, Matthias Carsten Putzke, Andrew Scott Hunter
Our understanding of quantum materials is commonly based on precise determinations of their electronic spectrum by spectroscopic means, most notably angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy. Both require atomicall ...
Melville2024Subwavelength imaging using a solid-immersion diffractive optical processor
Demetri Psaltis, Carlo Gigli, Niyazi Ulas Dinç, Yang Li
Phase imaging is widely used in biomedical imaging, sensing, and material characterization, among other fields. However, direct imaging of phase objects with subwavelength resolution remains a challenge. Here, we demonstrate subwavelength imaging of phase ...
Springernature2024Fluorescence microscopy: A statistics-optics perspective
Fundamental properties of light unavoidably impose features on images collected using fluorescence microscopes. Accounting for these features is often critical in quantitatively interpreting microscopy images, especially those gathering information at scal ...
