Is NGC 4631 a barred spiral galaxy?

The Astronomical Journal, 1991
High- and low-dispersion optical spectra of the giant H II region CM 67 near the center of the edge-on galaxy NGC 4631 have been obtained. Comparisons are made with radio observations to suggest the existence of a large bar in NGC 4631. Region CM 67 is shown to coincide in position with the easternmost peak of a triple radio-continuum source.

In silico, in vitro and ex vivo characterization of cystic fibrosis transmembrane conductance regulator pathogenic variants localized in the fourth intracellular loop and their rescue by modulators

British Journal of Pharmacology, Volume 182, Issue 24, Page 6063-6080, December 2025.
Background and Purpose Cystic fibrosis (CF) is due to loss‐of‐function variants of the CF transmembrane conductance regulator (CFTR) channel. The most effective treatment for people with CF carrying the F508del mutation is the triple combination of elexacaftor–tezacaftor–ivacaftor (ETI).

Impacts of Bar-driven Shear and Shocks on Star Formation

The Astrophysical Journal
Bars drive gas inflow. As the gas flows inward, shocks and shear occur along the bar dust lanes. Such shocks and shear can affect the star formation (SF) and change the gas properties.

Chandra Observation of NGC 1559: Eight Ultraluminous X-Ray Sources Including a Compact Binary Candidate

The Astrophysical Journal, 2023
Despite the 30 yr history of ultraluminous X-ray sources (ULXs) studies, issues such as the majority of their physical natures (i.e., neutron stars, stellar-mass black holes, or intermediate black holes) as well as the accretion mechanisms are still ...

AGN spiral galaxies in groups: effects of bars [PDF]

, 2014
We explore properties of barred active spiral galaxies in groups selected from the SDSS-DR7, with the aim of assessing the effects of bars on AGN and the role of the high density environment.

Somato‐Cognitive Action Network in Focal Dystonia

Movement Disorders, Volume 40, Issue 11, Page 2331-2343, November 2025.
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 ...

The CO-to-H2 Conversion Factor in the Barred Spiral Galaxy M83

The Astrophysical Journal
We analyze the CO-to-H _2 conversion factor ( α _CO ) in the nearby barred spiral galaxy M83. We present new H i observations from the VLA and single-dish GBT in the disk of the galaxy, and combine them with maps of CO(1-0) integrated intensity and dust ...

Stellar Populations, Bars and Secular Evolution in Late-Type Galaxies [PDF]

, 2000
We have done a robust statistical analysis of UBV color profiles of 257 Sbc barred and unbarred galaxies. We found that there is an excess of barred galaxies among the objects with null or positive (bluish inward) color gradients, which seems to indicate

CO OBSERVATIONS OF BARRED SPIRAL GALAXIES [PDF]

Journal of The Korean Astronomical Society, 2006
We present the results of a highly sensitive ( mK rms) survey toward the central parts of 22 barred spiral galaxies in line using the NRAO 12m telescope at Kitt Peak. Seven of the target galaxies were detected in CO; NGC 3686 has been detected with CO for the first time. We estimated central CO fluxes of and molecular gas masses of for those galaxies.

Simultaneous inhibition of TRIM24 and TRIM28 sensitises prostate cancer cells to antiandrogen therapy, decreasing VEGF signalling and angiogenesis

Molecular Oncology, Volume 19, Issue 10, Page 2797-2821, October 2025.
TRIM24 and TRIM28 are androgen receptor (AR) coregulators which exhibit increased expression with cancer progression. Both TRIM24 and TRIM28 combine to influence the response of castrate‐resistant prostate cancer (CRPC) cells to AR inhibitors by mediating AR signalling, regulation of MYC and upregulating VEGF to promote angiogenesis. Castrate‐resistant
