Robust and Irreversible Development in Cell Society as a General Consequence of Intra-Inter Dynamics

open access: yes, 1999
A dynamical systems scenario for developmental cell biology is proposed, based on numerical studies of a system with interacting units with internal dynamics and reproduction.

Non-adaptive phenotypic evolution of the endangered carnivore Lycaon pictus. [PDF]

open access: yesPLoS ONE, 2013
Decline in wild populations as a result of anthropogenic impact is widely considered to have evolutionary consequences for the species concerned. Here we examine changes in developmental stability in the painted hunting dog (Lycaon pictus), which once ...

Modelling developmental instability as the joint action of noise and stability: a Bayesian approach

open access: yesBMC Evolutionary Biology, 2002
Background Fluctuating asymmetry is assumed to measure individual and population level developmental stability. The latter may in turn show an association with stress, which can be observed through asymmetry-stress correlations.

TelAP2 links TelAP1 to the telomere complex in Trypanosoma brucei

open access: yesScientific Reports
The extracellular parasite Trypanosoma brucei evades the immune system of the mammalian host by periodically exchanging its variant surface glycoprotein (VSG) coat.

Familial influences on the full range of variability in attention and activity levels during adolescence: A longitudinal twin study [PDF]

open access: yes, 2015
To investigate familial influences on the full range of variability in attention and activity across adolescence, we collected maternal ratings of 339 twin pairs at ages 12, 14, and 16, and estimated the transmitted and new familial influences on ...

Pazopanib Combined With Vincristine and Irinotecan in Relapsed Wilms Tumor: Encouraging Outcomes in a Heavily Pretreated Pediatric Cohort

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background While Wilms tumor (WT) typically has a favorable prognosis, relapsed cases—especially those with high‐risk histology—remain therapeutically challenging after intensive frontline therapy. The combination of vincristine and irinotecan has demonstrated activity in pediatric solid tumors, and pazopanib, a multi‐targeted tyrosine kinase ...

A comparative fluctuating asymmetry study between two walnut (Juglans regia L.) populations may contribute as an early signal for bio-monitoring

open access: yesiForest - Biogeosciences and Forestry, 2010
Developmental stability, the ability of an individual to eliminate environmental disturbances while expressing a heritable phenotypic trait, was compared in two walnut (Juglans regia L.) populations, a natural and an artificial.

Uracil-containing DNA in Drosophila: stability, stage-specific accumulation, and developmental involvement. [PDF]

open access: yesPLoS Genetics, 2012
Base-excision repair and control of nucleotide pools safe-guard against permanent uracil accumulation in DNA relying on two key enzymes: uracil-DNA glycosylase and dUTPase.

Transcriptional Regulation of Gene Expression in \u3cem\u3eTetrahymena thermophila\u3c/em\u3e [PDF]

open access: yes, 1990
The only well-characterized study of gene expression in Tetrahymena thermophila (1) demonstrates that the temperature dependent expression of the Ser H3 gene is regulated at the level of mRNA stability.
