Anti-IgLON5 Disease 10 Years Later: What We Know and What We Do Not Know.

Anti-IgLON5 disease was identified 10 years ago, thanks to the discovery of IgLON5 antibodies and the joint effort of specialists in sleep medicine, neuroimmunology, and neuropathology. Without this collaboration, it would have been impossible to untangle fundamental aspects of this disease. After the seminal description in 2014, today there is growing evidence that most patients present a chronic progressive course with gait instability, abnormal movements, bulbar dysfunction, and a sleep disorder characterized by nonrapid eye movement and REM parasomnias, and obstructive sleep apnea with stridor.

Cuneus atrophy and Parkinsonian phenoconversion in cognitively unimpaired patients with isolated REM sleep behavior disorder.

Isolated rapid-eye-movement sleep behavior disorder (iRBD) is a strong predictor of Parkinson's disease and Dementia with Lewy bodies. Previous studies indicate that cortical atrophy in iRBD patients may be linked to cognitive impairment, but the pattern of atrophy is inconsistently reported. This study aimed to elucidate cortical atrophy patterns in a cognitively unimpaired iRBD cohort, focusing on regions associated with cognitive functions, particularly the cuneus/precuneus, and evaluated the predictive value for future phenoconversion.

Spatial distribution and isotopic signatures of N and C in mosses across Europe.

The accumulation of nitrogen (N) in moss tissue has proven to be a reliable marker of increasing N deposition. However, this measurement does not offer additional data about the origin of pollution. In this respect, the analysis of the N isotopic ratios might be a helpful tool in providing supplementary information about the nature of the nitrogenous species in biomonitoring surveys.

Chemically-Linked Heterostructures of Palladium Nanosheets and 2H-MoS.

The burgeoning field of 2D heterostructures targets the combination of 2D materials with 3D, 1D, or 0D nanomaterials. Among the most popular 2D materials, the 2H polytype of molybdenum disulfide (MoS) features a well-defined bandgap that becomes direct at the monolayer level, which can be exploited for photodetection. A notable limitation of 2H-MoS is its curtailed absorbance beyond the visible range.
