Clinical Manifestations.

Background: Research has demonstrated that spousal loss through widowhood or divorce are associated with an increased risk of dementia and deteriorated cognitive performance. This is likely due to high levels of stress characteristic of these life events. Evidence suggests that neuropathology typically seen in Alzheimer's disease, for example, β-amyloid (Aβ), may be a by-product of chronic stress.

Growing empathy through art therapy, life story, and relationships: experiential learning in adult day services.

Introduction: Empathy is a fundamental element of high-quality healthcare, though it has been shown to be in decline among medical students and residents. Appeals have therefore been made for the development of evidence-based empathy-enhancing experiential learning and training models. Bringing Art to Life (BATL) is a service-learning program designed within experiential learning pedagogy for psychology and pre-healthcare students.

Magnetosensitivity of tightly bound radical pairs in cryptochrome is enabled by the quantum Zeno effect.

The radical pair mechanism accounts for the magnetic field sensitivity of a large class of chemical reactions and is hypothesised to underpin numerous magnetosensitive traits in biology, including the avian compass. Traditionally, magnetic field sensitivity in this mechanism is attributed to radical pairs with weakly interacting, well-separated electrons; closely bound pairs were considered unresponsive to weak fields due to arrested spin dynamics. In this study, we challenge this view by examining the FAD-superoxide radical pair within cryptochrome, a protein hypothesised to function as a biological magnetosensor.

Multiomic molecular patterns of lipid dysregulation in a subphenotype of sepsis with higher shock incidence and mortality.

Background: Lipids play a critical role in defense against sepsis. We sought to investigate gene expression and lipidomic patterns of lipid dysregulation in sepsis.

Methods: Data from four adult sepsis studies were analyzed and findings were investigated in two external datasets.
