Population Scale Analysis of Centromeric Satellite DNA Reveals Highly Dynamic Evolutionary Patterns and Genomic Organization in Long-Tailed and Rhesus Macaques

Cells, 2022
Centromeric satellite DNA (cen-satDNA) consists of highly divergent repeat monomers, each approximately 171 base pairs in length. Here, we investigated the genetic diversity in the centromeric region of two primate species: long-tailed (Macaca ...

Simplified Communities of Seed-Dispersers Limit the Composition and Flow of Seeds in Edge Habitats

Frontiers in Ecology and Evolution, 2021
Edge effects, driven by human modification of landscapes, can have critical impacts on ecological processes such as species interactions, with cascading impacts on biodiversity as a whole. Characterizing how edges affect vital biotic interactions such as

The hemodynamic initial-dip consists of both volumetric and oxymetric changes reflecting localized spiking activity

Frontiers in Neuroscience, 2023
The initial-dip is a transient decrease frequently observed in functional neuroimaging signals, immediately after stimulus onset, believed to originate from a rise in deoxy-hemoglobin (HbR) caused by local neural activity.

Monkey metacognition could generate more insight [PDF]

Animal Behavior and Cognition, 2019
Monkeys demonstrate metacognition by avoiding memory tests when they forget, seeking information when ignorant, and gambling sensibly after making judgments. Some of this metacognition appears to be based on introspection of private mental states.

Cellular events of acute, resolving or progressive COVID-19 in SARS-CoV-2 infected non-human primates

Nature Communications, 2020
Here, Fahlberg et al. describe the cellular immune response during acute, resolving or progressive COVID-19 in SARS-CoV-2 infected non-human primates. The study identifies associations of monocytes and macrophage subtypes in lungs with disease outcome ...

Fetal skin as a pro-inflammatory organ: Evidence from a primate model of chorioamnionitis. [PDF]

, 2017
BackgroundIntrauterine infection is a primary cause of preterm birth and fetal injury. The pro-inflammatory role of the fetal skin in the setting of intrauterine infection remains poorly characterized. Whether or not inflammation of the fetal skin occurs

Conserved presence of G-quadruplex forming sequences in the Long Terminal Repeat Promoter of Lentiviruses [PDF]

, 2017
G-quadruplexes (G4s) are secondary structures of nucleic acids that epigenetically regulate cellular processes. In the human immunodeficiency lentivirus 1 (HIV-1), dynamic G4s are located in the unique viral LTR promoter.
