IC 5146 Dark Streamer: The First Reliable Candidate of Edge Collapse, Hub-filament Systems, and Intertwined Sub-filaments

open access: yesThe Astrophysical Journal, 2023
The paper presents an analysis of multiwavelength data of a nearby star-forming site, the IC 5146 dark streamer ( d ∼ 600 pc), which has been treated as a single and long filament, fl .

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

The Detection of Higher-order Millimeter Hydrogen Recombination Lines in the Large Magellanic Cloud

open access: yesThe Astrophysical Journal, 2023
We report the first extragalactic detection of the higher-order millimeter hydrogen recombination lines (Δ n > 2). The γ -, ϵ -, and η -transitions have been detected toward the millimeter continuum source N 105–1 A in the star-forming region N 105 in ...

Wolf - Rayet Stars in H II Regions [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1971
A catalogue of WR stars coincident with H II regions is presented. Approximately 44 per cent of the WR stars surveyed are found to be 'possibly' associated with nebulosity while association is considered to be 'probable' for 25 per cent of the cases.

New Infrared Sources Associated with H II Regions [PDF]

open access: yesSymposium - International Astronomical Union, 1973
Photometry and mapping in the wavelength range 1.65–20 μ of the H II regions W3 and NGC 7538 have led to the discovery of a dozen new infrared emission sources. The sources have flux densities ranging up to 10–23 Wm–2 Hz–1 at 20 μ and diameters from < 3 to 40″.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Investigating the Drivers of Electron Temperature Variations in H ii Regions with Keck-KCWI and VLT-MUSE

open access: yesThe Astrophysical Journal
H ii region electron temperatures are a critical ingredient in metallicity determinations, and recent observations have revealed systematic variations in the temperatures measured using different ions.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
