Transformative neuropathology is redefining human brain research by integrating foundational descriptive pathology with advanced methodologies. These approaches, spanning multi-omics studies and machine learning applications, will drive discovery for the identification of biomarkers, therapeutic targets, and complex disease patterns through comprehensive analyses of postmortem human brain tissue. [...]

Alpha-synuclein (aSyn) is an intrinsically disordered protein involved in phase separation and several age-associated neurodegenerative disorders, including Parkinson's disease. However, its function and pathological role remain elusive. [...]

Apraxia is a common symptom in Alzheimer's disease (AD) that reduces autonomy and quality of life. However, the neural basis underlying apraxia in AD, for example, reflected by functional connectivity (FC) alterations, remains unexplored. [...]

This systematic review aims to analyse the different safety aspects and evidence of CO2 as a contrast agent in vascular applications as an alternative to iodine-based contrast media (ICM). The review addresses clinical applications, contraindications, safety measures, and the impact of CO2 on the risk reduction of contrast-associated acute kidney injury (CA-AKI).A systematic literature search was conducted across PubMed, Web of Science, Embase, and Cochrane Library, focusing on relevant literature centred around clinical questions by the Contrast Media Safety Committee of the European Society of Urogenital Radiology.Eleven studies encompassing meta-analyses, randomised controlled trials, and comparative studies were included. [...]

Protein misfolding and aggregation is a major pathological hallmark in a variety of human conditions, including cancer, diabetes, and neurodegeneration. However, we still do not fully understand the role of protein accumulation in disease. [...]

Synucleins α, β, and γ are inherently disordered proteins that play essential roles in neuronal physiology and are increasingly recognized as key players in neurodegenerative disease mechanisms. The molecular basis of synucleinopathies, including Parkinson's disease, dementia with Lewy bodies, and multiple system atrophy, is the pathological aggregation and misfolding of synucleins. [...]

High altitude airline travel can have various effects on health in normal subjects. The effect of airline long distance travelling at high altitude on Parkinson's disease is not clearly known, and occasional reports suggest that after long-haul flights parkinsonian motor and aspects of nonmotor states may worsen temporarily. [...]

Short tandem repeats (STRs) are highly abundant in the human genome and their age-related somatic instability is emerging as a pivotal pathomechanism in repeat expansion disorders. Nevertheless, currently no analysis tool exists for genome-wide profiling of STR somatic instability. [...]

Although genome-wide association studies (GWAS) have uncovered many genetic variants linked to brain structure, much of its heritability remains unexplained. Short tandem repeats (STRs), which are rarely considered in GWAS, may contribute to this “missing heritability”. [...]

Thalamic subregions are commonly, but variably, affected by different forms of frontotemporal dementia. We aimed to better characterize thalamic subregional involvement in genetic frontotemporal dementia with a recently published thalamus segmentation tool that utilizes structural and diffusion MRI, offering additional assessment of mean diffusivity and a more fine-grained analysis of the pulvinar specifically compared to previous studies.
