NAD⁺ Reduction in Glutamatergic Neurons Induces Lipid Catabolism and Neuroinflammation in the Brain via SARM1

open access: yesAdvanced Science, EarlyView.
NAD⁺ homeostasis maintains neuronal integrity through opposing actions of NMNAT2 and SARM1. Loss of NMNAT2 in glutamatergic neurons reprograms cortical metabolism from glucose to lipid catabolism, depletes lipid stores, and triggers inflammation and neurodegeneration.

Long-time convergence of an Adaptive Biasing Force method [PDF]

open access: yes, 2007
We propose a proof of convergence of an adaptive method used in molecular dynamics to compute free energy profiles. Mathematically, it amounts to studying the long-time behavior of a stochastic process which satisfies a non-linear stochastic differential

Astrocytic PERK Deficiency Drives Prefrontal Circuit Dysfunction and Depressive‐Like Behaviors

open access: yesAdvanced Science, EarlyView.
Chen et al. show that the endoplasmic reticulum (ER) stress sensor PERK is downregulated in prefrontal cortex (PFC) astrocytes in major depressive disorder and in chronic‐stress mouse models. In young mice, astrocyte‐specific PERK loss reduces the synaptogenic cue thrombospondin‐1 (TSP1), leading to synaptic and circuit deficits and depressive‐like ...

OLS-Estimation of conditional and unconditional sigma- and beta-convergence of per capita income: Implications of Solow-Swan and Ramsey-Cass models [PDF]

open access: yes
In this paper I discuss the general statistical relationships between beta- and sigmaconvergence (for a definition see section 2) and the implications of the Solow-Swan and Ramsey-Cass model for an OLS-estimation of beta- and sigma-convergence of the log

Single‐Position Peptide Clustering for Peptidomics Reveals Novel Disease Biomarkers and Dysregulated Proteolytic Characteristics

open access: yesAdvanced Science, EarlyView.
A novel amino acid (aa)‐score‐based single‐position peptide clustering strategy is developed for peptidomics, enabling precise profiling of protein proteolysis in plasma from β‐thalassemia cohort. The method identifies new aa position‐based peptide cluster biomarkers validated by heavy‐labeled peptides, visualizes aggregated changes, uncovers disease ...

Accurate Generation of Conformational Ensembles for Intrinsically Disordered Proteins with IDPFold

open access: yesAdvanced Science, EarlyView.
In brief: IDPFold predicts the conformational ensembles of intrinsically disordered proteins (IDPs) from their amino acid sequences. The atomic structures generated by IDPFold offer crucial insights into the intricate relationship between IDP structures and their diverse biological functions.2 Abstract Intrinsically disordered proteins (IDPs) play ...

Integrated ERK‐PKA‐YAP/TAZ‐SHH Signaling Orchestrates Cortical Radial Glia Identity and Lineage Diversification

open access: yesAdvanced Science, EarlyView.
This study shows that ERK/PKA upregulation in mammalian cortical radial glia (RGs) sustains neurogenesis and suppresses gliogenesis. YAP/TAZ activation promotes ependymal cell formation, while enhanced SHH‐SMO signaling induces astrocyte, oligodendrocytes, and olfactory bulb interneuron generation.

What said the neoclassical and endogenous growth theories about Portugal? [PDF]

open access: yes
The aim of this paper is to present a further contribution, with panel data, to the analysis of absolute convergence ( and ), associated with the neoclassical theory, and conditional, associated with endogenous growth theory, of the sectoral productivity
