Secondary ion mass spectrometry imaging of Dictyostelium discoideum aggregation streams. [PDF]

PLoS ONE, 2014
High resolution imaging mass spectrometry could become a valuable tool for cell and developmental biology, but both, high spatial and mass spectral resolution are needed to enable this.

Increased throughput and ultra-high mass resolution in DESI FT-ICR MS imaging through new-generation external data acquisition system and advanced data processing approaches. [PDF]

Sci Rep, 2019
Desorption electrospray ionisation-mass spectrometry imaging (DESI-MSI) is a powerful imaging technique for the analysis of complex surfaces. However, the often highly complex nature of biological samples is particularly challenging for MSI approaches ...

Acyl-Lipid Δ⁶-Desaturase May Act as a First FAD in Cyanobacteria

Biomolecules, 2022
Fatty acid desaturases (FADs) play important roles in various metabolic and adaptive pathways in all living organisms. They represent a superfamily of oxygenases that introduce double bonds into the acyl chains of fatty acids (FAs).

Spontaneous Resolution of a Pulmonary Cystic Amyloidosis Mass

European Journal of Case Reports in Internal Medicine, 2022
Introduction: Amyloidosis is a rare illness characterized by the deposition in organs of amyloid, which can be detected by histological staining. Amyloidosis restricted to the lower respiratory tract is unusual.

Multimodal Image Registration and Fusion Offer Better Spatial Resolution for Mass Spectrometry Imaging [PDF]

, 2022
Super-resolution reconstruction has attracted increasing research interest in mass spectrometry imaging (MSI), but it remains a challenging ill-posed problem. In the present study, we proposed a Deep learning based SUper-REsolution model called DeepSURE,
