Advanced Science, EarlyView.This study explores the therapeutic potential of iNSC‐Exo via local and systemic delivery in TBI mice. It is found that iNSC‐Exo enhances NRXN signaling through Microglia_Nrg3 and Microglia_Rarb, effectively promoting functional and neurological recovery, suggesting a new therapeutic strategy for TBI. Abstract Traumatic brain injury (TBI) poses serious

Powerful outflows in the central parsecs of the low-luminosity active galactic nucleus NGC 1386 [PDF]
, 2017 Low-luminosity Active Galactic Nuclei, i.e. L_bol/L_edd ~ 10^-6 - 10^-3, constitute the bulk population of Active Galactic Nuclei (AGNs). Powerful jets, common in these objects, are a crucial source of feedback energy driving mass outflows into the host ...

Advanced Science, EarlyView.Leukemic blasts induce membrane depolarization in mesenchymal stromal cells (MSCs), contributing to a dysfunctional niche that favors leukemia progression. Here, it is demonstrated that restoring the expression of CaV1.2 calcium channel in AML‐MSCs repolarizes their membrane potential, reprogramming them toward a healthy phenotype.

ACTIVE GALACTIC NUCLEUS FEEDBACK IN THE HOT HALO OF NGC 4649
The Astrophysical Journal, 2014 Using the deepest available Chandra observations of NGC 4649, we find strong evidences of cavities, ripples, and ring-like structures in the hot interstellar medium that appear to be morphologically related with the central radio emission. These structures show no significant temperature variations in correspondence with higher pressure regions (0.5 ...

Millikelvin Intracellular Nanothermometry with Nanodiamonds
Advanced Science, EarlyView.Nanothermometry in living cells is crucial for understanding heat diffusion and advancing cellular biology and drug discovery. Previous studies have reported controversial intracellular temperature variations. Using nanodiamond nanothermometry in macrophages, it is found that, in such experimental setting, apparent temperature changes are actually due ...

HST/WFC3 Observations of an Off-Nuclear Superbubble in Arp 220 [PDF]
, 2015 We present a high spatial resolution optical and infrared study of the circumnuclear region in Arp 220, a late-stage galaxy merger. Narrowband imaging using HST/WFC3 has resolved the previously observed peak in H$\alpha$+[NII] emission into a bubble ...

The weak Fe fluorescence line and long-term X-ray evolution of the Compton-thick active galactic nucleus in NGC 7674 [PDF]
, 2016 We present NuSTAR X-ray observations of the active galactic nucleus (AGN) in NGC 7674. The source shows a flat X-ray spectrum, suggesting that it is obscured by Compton-thick gas columns.

Calorimetry of Active Galactic Nucleus jets: testing plasma composition in Cygnus A
, 2012 We examine plasma composition of jets in active galactic nuclei through the comparison of the total pressure ($P$) with partial pressures of electrons and protons in a cocoon.
