Novel Liquid Biopsy in Gastrointestinal Cancers

open access: yesJournal of Gastroenterology and Hepatology, Volume 41, Issue 2, Page 546-555, February 2026.
ABSTRACT Gastrointestinal (GI) cancers represent a significant global health burden, being among the leading causes of cancer‐related deaths. The prognosis for patients remains unsatisfactory, largely because most cancers are detected at advanced stages.

Hydro-Gravitational Dynamics of Planets and Dark Energy

open access: yesJournal of Applied Fluid Mechanics, 2009
Self gravitational fluid mechanical methods termed hydro-gravitational-dynamics (HGD) predict plasma fragmentation 0.03 Myr after the turbulent big bang to form protosuperclustervoids, turbulent protosuperclusters, and protogalaxies at the 0.3 Myr ...

Formation of Asteroid (16) Psyche by a Giant Impact

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Asteroid (16) Psyche is the largest likely metal‐rich asteroid in the Solar System and the target of the NASA Psyche mission. The mission aims to determine whether the asteroid is the core of a differentiated planetesimal that lost its mantle via a giant impact.

IRAS 02366 - 3101 - an accretion disk candidate among luminous IRAS galaxies

open access: yesThe Astrophysical Journal, 1991
In this Letter we present the detection, for the first time, of double-peaked broad Balmer Hα and Hβ emission-line profiles in a luminous IRAS galaxy : IRAS 02366-3101 with log L FIR =10.94 L ⊙ . This detection shows that IRAS 02366-3101 is a candidate to host an accretion disk around a supermassive black hole in its nucleus, although other ...

Discovering the Mass-Scaled Damping Timescale from Microquasars to Blazars

open access: yesThe Astrophysical Journal Letters
Studying the variability of the accretion disks of black holes and jets is important to identify their internal physical processes. In this Letter, we obtain the characteristic damping timescale of 34 blazars and 7 microquasars from the Fermi-Large Area ...

Heavy Metal Contamination in Chocolates and Candies: Sources, Health Risks, and Analytical Insights

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
The presence of heavy metals in chocolates and candies poses growing public health concerns, particularly for children who are frequent consumers. This review consolidates evidence on the occurrence, sources, toxicological impacts, and analytical monitoring of metals, including Pb, Cd, Hg, As, Cr, Ni, and Al, in confectionery products.

What Kinds of Accretion Disks Are There in the Nuclei of Radio Galaxies? [PDF]

open access: yesPublications of the Astronomical Society of Japan, 2010
It seems to be a widely accepted opinion that the types of accretion disks (or flows) generally realized in the nuclei of radio galaxies and in further lower mass-accretion rate nuclei are inner, hot, optically thin, radiatively inefficient accretion flows (RIAFs) surrounded by outer, cool, optically thick, standard-type accretion disks.

The Multiband Emission of the Two-component Gamma-Ray Burst Jet Influenced by Progenitor Winds within the Accretion Disk of Active Galactic Nuclei

open access: yesThe Astrophysical Journal
Gamma-ray bursts (GRBs), both from the merger of binary compact objects (short GRBs) and the collapse of massive stars (long GRBs), are expected to occur in dense environments, e.g., the accretion disks of active galactic nuclei (AGNs).

The Stochastic‐Dissipative Störmer Problem‐Trajectories and Radiation Patterns

open access: yesAnnalen der Physik, Volume 537, Issue 12, December 2025.
We consider charged particle motion and radiation in a dipole magnetic field, in the presence of friction and of stochastic forces. The numerical solutions of the Langevin equation reveal how these forces modify the complex dynamics of particles, and they offer some new insights into the nonlinear processes relevant to planetary radiation belts ...

A Deep Metagenomic Snapshot as a Proof‐of‐Concept for Resource Generation: Simultaneous Assembly of Host, Food, and Microbiome Genomes From Stingless Bee Larval Food

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study serves as a proof‐of‐concept, demonstrating that deep shotgun sequencing of a single complex sample—stingless bee larval food—can simultaneously generate multiple genomic resources. From this dataset, we assembled three genomes (a near‐complete bacterium, a draft host mitochondrion, and a fragmented plant chloroplast) with varying ...
