Illuminating Satellite Cells: Light Sheet Fluorescence Microscopy for 3D Imaging of Murine Skeletal Muscles Damaged by Ex Vivo Forced Eccentric Contraction

Microscopy Research and Technique, EarlyView.
This study presents the light sheet fluorescence microscopy (LSFM) as a tool for 3D‐imaging of whole skeletal muscle to reveal satellite cells (SCs), the muscle stem cells that activate following damage to repair injured tissue. After tissue clearing and whole‐mount staining process aimed to enable optical access and specific cell labeling (1), murine ...

The QPO in RE J1034+396 Originates in the Hot Corona

The Astrophysical Journal
RE J1034+396 is one of the few active galactic nuclei (AGNs) with a significant quasiperiodic oscillation (QPO). The QPO has been observed in over 1 Ms of XMM-Newton observations spanning over a decade. We investigate the power spectral density function (

ATAC‐seq in Emerging Model Organisms: Challenges and Strategies

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Principle of ATAC‐seq (left), overview of arthropod species with published ATAC‐seq data (middle), summary of experimental design (right). ABSTRACT The Assay for Transposase‐Accessible Chromatin with sequencing (ATAC‐seq) is a versatile and widely utilized method for identifying potential regulatory regions, such as promoters and enhancers, within a ...

Observational Signatures of Galactic Winds Powered by Active Galactic Nuclei

, 2014
We predict the observational signatures of galaxy scale outflows powered by active galactic nuclei (AGN). Most of the emission is produced by the forward shock driven into the ambient interstellar medium (ISM) rather than by the reverse shock.

Diastereoselectivity in the Synthesis of m‐ and p‐Substituted 3‐Aryl‐2‐trichloromethyl‐1,3‐thiazolidin‐4‐one Sulfoxides With Oxone

Journal of Heterocyclic Chemistry, EarlyView.
Highly selective oxidation of thiazolidin‐4‐ones to sulfoxides and sulfones with Oxone and KMnO4, respectively. ABSTRACT S‐Oxidation of 3‐Aryl‐2‐trichloromethyl‐1,3‐thiazolidin‐4‐ones with Oxone was investigated. For all compounds evaluated, selective oxidation to the sulfoxide versus the sulfone was realized using 3 equivalents of Oxone at room ...

Mid-infrared Variability in Nearby Galaxies from the MaNGA Sample

The Astrophysical Journal
We use mid-infrared variability in galaxies to search for active galactic nuclei (AGN) in the local universe. We use a sample of 10,220 galaxies from the Mapping Nearby Galaxies at Apache Point Observatory survey, part of the Sloan Digital Sky Survey ...

The physics of galactic winds driven by active galactic nuclei

, 2012
Active galactic nuclei (AGN) drive fast winds in the interstellar medium of their host galaxies. It is commonly assumed that the high ambient densities and intense radiation fields in galactic nuclei imply short cooling times, thus making the outflows ...

Somato‐Cognitive Action Network in Focal Dystonia

Movement Disorders, EarlyView.
Abstract Background The central pathology causing idiopathic focal dystonia remains unclear. The recently identified somato‐cognitive action network (SCAN) has been implicated. Objective We tested whether the effector‐agnostic SCAN may constitute a central pathology shared across dystonia subtypes, whereas the effector‐specific regions in the primary ...

PEARLS: Discovery of Point-source Features within Galaxies in the North Ecliptic Pole Time Domain Field

The Astrophysical Journal
The first public 0.9–4.4 μ m NIRCam images of the North Ecliptic Pole Time Domain Field uncovered galaxies displaying point-source features in their cores as seen in the longer-wavelength filters. We visually identified a sample of 66 galaxies (∼1 galaxy
