Post‐LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor
Cytoskeleton, EarlyView.ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

Cannabinoid Receptor Involvement in Stress-Induced Cocaine Reinstatement: Potential Interaction with Noradrenergic Pathways [PDF]
, 2012 This study examined the role of endocannabinoid signaling in stress-induced reinstatement of cocaine seeking and explored the interaction between noradrenergic and endocannabinergic systems in the process.

Movement Disorders Clinical Practice, EarlyView.Abstract Background Parkinson's disease (PD) is associated with both motor and non‐motor symptoms, which collectively impact activities of daily living (ADLs) and contribute to the loss of functional independence. There is a lack of understanding of how non‐motor symptoms drive this loss in independence.

Movement Disorders, EarlyView.Abstract Background Anxiety and autonomic dysfunction are frequent non‐motor symptoms of Parkinson's disease (PD). Their relationship, as well as the neural mechanisms underlying this relationship, remain unexplored. Objectives We aimed to investigate the relationship between cardiovascular functions and anxiety in PD and the structural neural changes ...

Locus coeruleus contrast and diffusivity metrics differentially relate to age and memory performance
Scientific ReportsNeurocognitive aging researchers are increasingly focused on the locus coeruleus, a neuromodulatory brainstem structure that degrades with age. With this rapid growth, the field will benefit from consensus regarding which magnetic resonance imaging (MRI)
