Demonstrator training needs to be active and focused on personalized student learning in bioscience teaching laboratories.

FEBS Open Bio 2021 Sep 12. Epub 2021 Sep 12.

School of Life sciences, University of Liverpool, Crown Street, Liverpool, L69 7ZB, United Kingdom.

Demonstrators spend significant time with students on a weekly basis in instructional labs and are well poised to offer students meaningful learning. Most often, effective demonstrator training is neglected due to time and resource restraints and it is clear more attention is needed. We hypothesised that students' learning experience in labs would improve if demonstrators were well trained particularly across three overlapping learning domains: subject-specific knowledge (cognitive and psychomotor), problem solving (cognitive) and group management including personalized student learning strategies (affective).

Mol Psychiatry 2021 Aug 30. Epub 2021 Aug 30.

Eisai Inc., Neurology Business Group, Woodcliff Lake, NJ, USA.

Breakthroughs in molecular medicine have positioned the amyloid-β (Aβ) pathway at the center of Alzheimer's disease (AD) pathophysiology. While the detailed molecular mechanisms of the pathway and the spatial-temporal dynamics leading to synaptic failure, neurodegeneration, and clinical onset are still under intense investigation, the established biochemical alterations of the Aβ cycle remain the core biological hallmark of AD and are promising targets for the development of disease-modifying therapies. Here, we systematically review and update the vast state-of-the-art literature of Aβ science with evidence from basic research studies to human genetic and multi-modal biomarker investigations, which supports a crucial role of Aβ pathway dyshomeostasis in AD pathophysiological dynamics.
