Reliability of Static and Dynamic Network Metrics in the Resting-State: A MEG-Beamformed Connectivity Analysis

open access: yesFrontiers in Neuroscience, 2018
The resting activity of the brain can be described by so-called intrinsic connectivity networks (ICNs), which consist of spatially and temporally distributed, but functionally connected, nodes.

Geometric Time and Causal Time in Relativistic Lagrangian Mechanics [PDF]

open access: yes, 2016
In this article, we argue that two distinct types of time should be taken into account in relativistic physics: a geometric time, which emanates from the structure of spacetime and its metrics, and a causal time, indicating the flow from the past to the ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Unraveling the influences of hemodynamic lag and intrinsic cerebrovascular reactivity on functional metrics in ischemic stroke

open access: yesNeuroImage
Resting-state functional magnetic resonance imaging (rs-fMRI) is a prominent tool for investigating functional deficits in stroke patients. However, the extent to which the hemodynamic lags (LAG) and the intrinsic cerebrovascular reactivity (iCVR) may ...

Characterizing donation behavior from psychophysiological indices of narrative experience

open access: yesFrontiers in Neuroscience, 2015
Research on narrative persuasion has yet to investigate whether this process influences behavior. The current study explored whether: 1) a narrative could persuade participants to donate to a charity, a prosocial, behavioral decision; 2 ...

Export of miRNAs from activated macrophages is cooperative and HuR‐dependent

open access: yesFEBS Letters, EarlyView.
This study uncovers a new mechanism for miRNA export regulation in mammalian cells, driven by the RNA‐binding protein HuR. In macrophages, HuR cooperatively binds with miRNAs to export both low‐ and high‐affinity substrates, thereby influencing macrophage activation.

Aggressive prostate cancer is associated with pericyte dysfunction

open access: yesMolecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Liquid biopsy epigenetics: establishing a molecular profile based on cell‐free DNA

open access: yesMolecular Oncology, EarlyView.
Cell‐free DNA (cfDNA) fragments in plasma from cancer patients carry epigenetic signatures reflecting their cells of origin. These epigenetic features include DNA methylation, nucleosome modifications, and variations in fragmentation. This review describes the biological properties of each feature and explores optimal strategies for harnessing cfDNA ...

Intrinsic connections for Levi metrics

open access: yesManuscripta Mathematica, 1992
It is supposed that a CR manifold carries a metric which, on the maximal complex subspace of the tangent space, agrees with a choice of a Levi form. By using Cartan's moving frame method the local equivalence problem is solved. Then this solution is interpreted as a connection in a principal bundle. Finally, there are obtained the curvature and torsion

Class IIa HDACs forced degradation allows resensitization of oxaliplatin‐resistant FBXW7‐mutated colorectal cancer

open access: yesMolecular Oncology, EarlyView.
HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...
