Drosophila Mechanosensory Transduction

Authors Hehlert P, Zhang W, Göpfert MC Journal Trends in Neurosciences Citation Trends Neurosci. 2020 Nov 27:S0166-2236(20)30251-4. Abstract Mechanosensation in Drosophila relies on sensory neurons transducing mechanical stimuli into ionic currents. The molecular mechanisms of this transduction are in the process of being revealed. Transduction relies on mechanogated ion channels

“Ion Type and Valency Differentially Drive Vimentin Tetramers into Intermediate Filaments or Higher Order Assemblies”

Authors Denz M, Marschall M, Herrmann H, Köster S Journal Soft Matter Citation Soft Matter. 2020 Nov 25. Abstract Vimentin intermediate filaments, together with actin filaments and microtubules, constitute the cytoskeleton in cells of mesenchymal origin. The mechanical properties of the filaments themselves are encoded in their molecular architecture and

Efficient modeling of three-dimensional convection–diffusion problems in stationary flows

Authors Thiele JC, Gregor I, Karedla N, Enderlein J Journal Physics of Fluids Citation Physics of Fluids 32, 112015 (2020). Abstract A large number of transport processes in physics, chemistry, and engineering are described by a convection–diffusion equation. This equation is notoriously difficult to solve due to the presence of

From iPS Cells to Rodents and Nonhuman Primates: Filling Gaps in Modeling Parkinson’s Disease

Authors Outeiro TF, Heutink P, Bezard E, Cenci AM Journal Movement Disorders Citation Mov Disord. 2020 Nov 16. Abstract Parkinson’s disease (PD) is primarily known as a movement disorder because of typical clinical manifestations associated with the loss of dopaminergic neurons in the substantia nigra. However, it is now widely

Pharmacological Modulators of Tau Aggregation and Spreading

Authors Dominguez-Meijide A, Vasili E, Outeiro TF Journal Brain Science Citation Brain Sci. 2020 Nov 13;10(11):E858. Abstract Tauopathies are neurodegenerative disorders characterized by the deposition of aggregates composed of abnormal tau protein in the brain. Additionally, misfolded forms of tau can propagate from cell to cell and throughout the brain.

Variational Multiscale Nonparametric Regression: Algorithms and Implementation

Authors del Alamo M, Li H, Munk A, Werner F Journal Algorithms Citation Algorithms 2020, 13(11), 296. Abstract Many modern statistically efficient methods come with tremendous computational challenges, often leading to large-scale optimisation problems. In this work, we examine such computational issues for recently developed estimation methods in nonparametric regression
