Rapid eye movement (REM) sleep behaviour disorder (RBD) is a REM parasomnia that often predicts the later occurrence of alpha-synucleinopathies. Variants in the gene encoding for the lysosomal enzyme glucocerebrosidase, GBA, strongly increase the risk of RBD. In a GBA1-mouse model recently shown to mimic prodromal stages of α-synucleinopathy, we now demonstrate striking REM and NREM electroencephalographic sleep abnormalities accompanied by distinct structural changes in the more widespread sleep neurocircuitry.

Macroautophagy/autophagy is an evolutionarily conserved process through which cells degrade cytoplasmic substances via autophagosomes. During the initiation of autophagosome formation, the ULK/Atg1 complex serves as a scaffold that recruits and regulates downstream ATG/Atg proteins and ATG9/Atg9-containing vesicles. Despite the essential role of the ULK/Atg1 complex, its components have changed during evolution; the ULK complex in mammals consists of ULK1 (or ULK2), RB1CC1, ATG13, and ATG101, whereas the Atg1 complex in the yeast lacks Atg101 but instead has Atg29 and Atg31 along with Atg17.

The coupling between transition metal dichalcogenides (TMDCs) and SrTiO has recently emerged as a fertile platform for discovering interfacial phenomena, where particle interactions, lattice coupling, and dielectric screening give rise to interesting physical effects. These hybrid systems hold significant promise for two-dimensional (2D) electronics, ferroelectric state control, and metastable phase engineering. However, effective modulation of the interfacial electronic structure remains a critical challenge.

The rice root system mediates nutrient uptake while adapting to tillage, management, and environmental changes. While optimized nitrogen (N) supply is known to enhance 2-acetyl-1-pyrroline (2-AP) biosynthesis in fragrant rice, the underlying mechanisms linking nitrogen availability, root development, and their combined effects on physiological processes and aroma formation remain unclear. To address this knowledge gap, we conducted a pot experiment employing two fragrant rice cultivars (Huahangxiangyinzhen and Qingxiangyou19xiang) under three nitrogen regimes (0, 1.

Background: Aortic structural degeneration occurs with aging; however, 3-dimensional geometric remodeling has not been well characterized in large populations.
Methods: We segmented the thoracic aorta from magnetic resonance images of 56 164 UKB (UK Biobank) participants and computed tomography images of 9417 PMBB (Penn Medicine Biobank) participants. We quantified structural measurements of elongation, dilation, tortuosity, and curvature across the thoracic aorta.

Although there is considerable research into the impact of homicide on surviving family members, research is limited on subjective experiences of those who lost a parent due to homicide during childhood. Through interpretative phenomenological analysis, we conducted and analyzed in-depth semi-structured interviews, to explore lived experiences and perspectives of post-traumatic growth with adults who lost a parent due to homicide as a child. We developed five group experiential themes: 1.
