The Progeny of Stellar Dynamics and Stellar Evolution within an N-body model of NGC 188 [PDF]

open access: yes, 2009
We present a direct N-body simulation modeling the evolution of the old (7 Gyr) open cluster NGC 188. This is the first N-body open cluster simulation whose initial binary population is directly defined by observations of a specific open cluster: M35 ...

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

open access: yesMolecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Creation of body color mutants by CRISPR/Cas9 gene editing in largemouth bass, Micropterus salmoides

open access: yesAquaculture Reports
Largemouth bass (LMB, Microterus salmoides) is an important commercial freshwater fish, and body color is a key economic trait for quality improvement. Gene editing has not been established in LMB due to the unavailability of one-cell fertilized eggs. In

Two- and three-body color flux tubes in the Chromo Dielectric Model

open access: yes, 2004
Using the framework of the Chromo Dielectric Model we perform an analysis of color electric flux tubes in meson-like $q\bar{q}$ and baryon-like $qqq$ quark configurations.

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

open access: yesMolecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

Thyroid hormone regulates both melanin and non-melanin pigmentation in Sinibrama taeniatus via three types of chromophores

open access: yesFrontiers in Marine Science
IntroductionBody color is a prominent phenotypic trait and a significant economic characteristic in fish. While current research mainly examines the effects of genetic factors, less emphasis has been placed on the role of endogenous hormones in fish body

The effect of aquarium color background on the survival, growth performance, body coloration, and enzymatic activity of laboratory cultured Cherax quadricarinatus juveniles

open access: yesAquaculture Reports, 2023
The effect of different background colors (red, yellow, blue, green, white, and black) on crayfish Cherax quadricarinatus juveniles was evaluated over a 50-day rearing period. Survival, growth, body color, and enzymatic activity were assessed.

Mean-field theory of baryonic matter for QCD in the large $N_{c}$ and heavy quark mass limits

open access: yes, 2013
We discuss theoretical issues pertaining to baryonic matter in the combined heavy-quark and large $N_c$ limits of QCD. Witten's classic argument that baryons and interacting systems of baryons can be described in a mean-field approximation with each of ...

A hypothesis for the color bimodality of Jupiter Trojans [PDF]

open access: yes, 2016
One of the most enigmatic and hitherto unexplained properties of Jupiter Trojans is their bimodal color distribution. This bimodality is indicative of two sub-populations within the Trojans, which have distinct size distributions.

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

open access: yesMolecular 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.
