Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Cardiovascular safety of fixed-dose extended-release naltrexone/bupropion in clinical practiceKey takeaways

Obesity Pillars
Background: The fixed-dose extended-release combination of naltrexone/bupropion (NB-ER) is indicated to treat overweight and obesity in adults as an adjunct to a reduced-calorie diet and increased physical activity.

Evaluation of a rapid biosensor tool for measuring PAH availability in petroleum-impacted sediment

Environmental Advances, 2021
Decades of research have shown that the concentration of freely dissolved PAH (Cfree) in sediment correlates with PAH bioavailability and toxicity to aquatic organisms.

Critical exponents of the driven elastic string in a disordered medium

, 2005
We analyze the harmonic elastic string driven through a continuous random potential above the depinning threshold. The velocity exponent beta = 0.33(2) is calculated.

Dynamical Critical Exponent for Two-Species Totally Asymmetric Diffusion on a Ring [PDF]

, 2010
We present a study of the two species totally asymmetric diffusion model using the Bethe ansatz. The Hamiltonian has $U_q(SU(3))$ symmetry. We derive the nested Bethe ansatz equations and obtain the dynamical critical exponent from the finite-size ...

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

The minimum exponent of the primitive digraphs on the given number of arcs [PDF]

Opuscula Mathematica, 2004
Primitive digraphs on \(n\) vertices, \(k\) arcs and girth \(s\) are considered. By \(a(n,k,s)\) we mean the minimum exponent taken over all such digraphs. We estimate the number \(a(n,k,s)\) using the Frobenius number for special values of \(k\) and \(s\

Simplified Successive Cancellation Decoding of Polar Codes With Medium-Dimensional Binary Kernels

IEEE Access, 2018
A method is proposed, called l-formula, to design efficient successive cancellation (SC) decoding of polar codes with medium-dimensional binary kernels (dimensions up to 16).

Exact Random Coding Secrecy Exponents for the Wiretap Channel

, 2016
We analyze the exact exponential decay rate of the expected amount of information leaked to the wiretapper in Wyner's wiretap channel setting using wiretap channel codes constructed from both i.i.d. and constant-composition random codes. Our analysis for
