HCG 57: Evidence for Shock-heated Intergalactic Gas from X-Rays and Optical Emission Line Spectroscopy

The Astrophysical Journal
We present Chandra and XMM-Newton X-ray observations of the compact group HCG 57, and optical integral field spectroscopy of the interacting galaxy pair HCG 57A/D.

Dynamics of Galaxy Interactions [PDF]

, 1998
This review briefly and very informally summarizes some of my ongoing research. One unifying theme in my work is the use of computers to bridge the gap between human and astronomical time-scales. Galactic collisions are an example; the dynamics of interacting galaxies can be visualized with numerical simulations.

Inhibition of Ornithine Decarboxylase 1 Mitigates Denervation‐Induced Muscle Atrophy by Suppressing Proteolysis and Preserving Muscle Stem Cell Homeostasis

Cell Proliferation, EarlyView.
Polyamine metabolism is innervation responsive and involved in denervation‐induced muscle atrophy. Inhibition of polyamine metabolism attenuates muscle atrophy by restraining proteolysis and preserving MuSCs homeostasis. Denervation‐induced activation of FAP‐derived FGF7 drives premature MuSCs activation, while DFMO suppresses this paracrine cue to ...

Behavioural Determinants of Post‐Brushing Dental Plaque Levels: A Video‐Based Analysis

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Objectives Toothbrushing remains the most widely practiced method for dental plaque removal. However, evidence‐based guidance on optimal brushing method, duration, toothbrush bristle wear, and dentifrice quantity is still insufficient. This study aimed to identify behavioural factors associated with post‐brushing dental plaque levels using ...

Differences in the Gastric Microbiotas of Neighboring Populations With Divergent Risks of Gastric Cancer

Journal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Background Although Helicobacter pylori plays a central role in gastric cancer (GC), other microorganisms involved in gastric dysbiosis may also impact carcinogenesis. We aimed to characterize gastric dysbiosis and its role in the transition from non‐atrophic gastritis (NAG) to gastric premalignant lesions (GPLs) in two populations from Nariño,

Disclosing Submillimeter Galaxy Formation: Mergers or Secular Evolution?

The Astrophysical Journal
We analyze the morphology of 125 submillimeter galaxies (SMGs) in the PRIMER-COSMOS field using double Sérsic modeling on JWST NIRCam images across six bands (F150W, F200W, F277W, F356W, F410M, and F444W), with SMGs being classified by the bulge Sérsic ...

Modular training resources for bioimage analysis

Journal of Microscopy, EarlyView.
Abstract Modern microscopy enables us to measure structural and dynamical properties of many biological processes and is therefore an indispensable research tool. However, the amount and complexity of the produced imaging data is steadily increasing.

GloBIAS survey results – An insight into the global bioimage analysis community

Journal of Microscopy, EarlyView.
Abstract There is a global need for bioimage analysis (BIA) as advances in life sciences increasingly rely on cutting‐edge imaging systems that have dramatically expanded the complexity and dimensionality of biological images. Turning these data into scientific discoveries requires scientists with effective data management skills and knowledge of state‐

A Deep Dive into the NGC 741 Galaxy Group: Insights into a Spectacular Head-tail Radio Galaxy from VLA, MeerKAT, uGMRT, and LOFAR

The Astrophysical Journal
We present deep, wideband multifrequency radio observations (144 MHz−8 GHz) of the remarkable galaxy group NGC 741, which yield crucial insights into the interaction between the infalling head-tail radio galaxy (NGC 742) and the main group.
