Assortative mating across nine psychiatric disorders is consistent and persistent over cultures and generations.

Emerging evidence has shown that assortative mating (AM) is a key factor that shapes the landscape of complex human traits. It can increase the overall prevalence of disorders, influence occurrences of comorbidities, and bias estimation of genetic architectures. However, there is lack of large-scale studies to examine the cultural differences and the generational trends of AM for psychiatric disorders.

Acylcarnitines metabolism in depression: association with diagnostic status, depression severity and symptom profile in the NESDA cohort.

Acylcarnitines (ACs) are involved in bioenergetics processes that may play a role in the pathophysiology of depression. Previous genomic evidence identified four ACs potentially linked to depression risk. We carried forward these ACs and tested the association of their circulating levels with Major Depressive Disorder (MDD) diagnosis, overall depression severity and specific symptom profiles.

Lysyl Oxidase-like 2 Dysregulation Increases the Risk of Post-Operative Fibrotic Scars Formation in the Female Reproductive Tract: A Novel Therapeutic Target to Reduce Fibrogenesis.

The formation of fibrotic bands in female reproductive system, including the uterus, after abdominal and pelvic surgeries, is an important medical challenge associated with many complications, including infertility and pain. Investigating the role of different molecules involved in fibrosis and adhesion formation may help in the development of new drugs to prevent this disorder. Lysyl oxidase-like 2 (LoxL2) is a copper-dependent enzyme that catalyzes the cross-linking of collagen and elastin fibers in the extracellular matrix (ECM) to stabilize ECM.

Effectiveness of interventions for mobile phone distracted pedestrians: A systematic review.

Introduction: Mobile phones are used universally due to their versatility and easy-to-use features; this includes when users are walking and when crossing streets. At intersections, using a mobile phone is a secondary task that can distract from the primary task of scanning the road environment and ensuring it is safe to traverse. Such a distraction has been shown to increase risky pedestrian behavior compared to non-distracted behavior.

Factors reducing the detectability of train horns by road users: A laboratory study.

Level crossing safety is a well-researched safety issue worldwide, but little attention has been placed on the safety benefits of using train horns when a train approaches a level crossing. Given train horns' adverse effects on the health and well-being of residents living near rail tracks, the use of train horns must be beneficial to safety. The current study sought to determine in a laboratory environment whether road users (N = 31) can detect the range of train horns observed in Australia in terms of loudness and duration, using high-definition audio recordings from railway crossings.

The Spectrum of Alzheimer-Type Pathology in Cognitively Normal Individuals.
