A satellite explosion in the genome of holocentric nematodes. [PDF]
PLoS ONE, 2013 Centromere sequences in the genome are associated with the formation of kinetochores, where spindle microtubules grow in mitosis. Centromere sequences usually have long tandem repeats (satellites).

Stretching the Rules: Monocentric Chromosomes with Multiple Centromere Domains [PDF]
, 2012 The centromere is a functional chromosome domain that is essential for faithful chromosome segregation during cell division and that can be reliably identified by the presence of the centromere-specific histone H3 variant CenH3.

Frequency and significance of Ras, Tert promoter, and Braf mutations in cytologically indeterminate thyroid nodules: A monocentric case series at a tertiary-level Endocrinology unit [PDF]
, 2017 PurposeThe management of thyroid nodules of indeterminate cytology is controversial. Our study aimed to establish the frequency and significance of H-,K-,N-RAS, TERT promoter, and BRAF gene mutations in thyroid nodes of indeterminate cytology and to ...

Galilean monocentric multiscale optical systems
Optics Express, 2017 The first generation of monocentric multiscale gigapixel cameras used Keplerian designs to enable full field coverage. This paper considers alternative designs that remove the requirement that adjacent subimages overlap. Removing this constraint enables Galilean designs that reduce system volume and improve relative illumination and image quality.

Chromosome number evolves at equal rates in holocentric and monocentric clades.
PLoS Genetics, 2020 Despite the fundamental role of centromeres two different types are observed across plants and animals. Monocentric chromosomes possess a single region that function as the centromere while in holocentric chromosomes centromere activity is spread across ...

Chromosome diversity in Buthidae and Chactidae scorpions from Brazilian fauna: Diploid number and distribution of repetitive DNA sequences [PDF]
Genetics and Molecular Biology, 2023 In this work, we analyzed cytogenetically eight Chactidae and Buthidae, including the localization of repetitive DNA sequences. The chactids possess monocentric chromosomes and the highest diploid numbers (2n=50 in Brotheas amazonicus, 2n=36 in ...

Inferring urban polycentricity from the variability in human mobility patterns
Scientific Reports, 2023 The polycentric city model has gained popularity in spatial planning policy, since it is believed to overcome some of the problems often present in monocentric metropolises, ranging from congestion to difficult accessibility to jobs and services. However,

Behavior of dicentric chromosomes in budding yeast.
PLoS Genetics, 2021 DNA double-strand breaks arise in vivo when a dicentric chromosome (two centromeres on one chromosome) goes through mitosis with the two centromeres attached to opposite spindle pole bodies.
