ENVIRONMENTAL STRESS ON THE REPRODUCTION OF NON-HUMAN PRIMATES

Biotropia: The Southeast Asian Journal of Tropical Biology, 2021
The aim of this review paper is to present some aspects of environmental stress, such as climate change and food limitation that could affect nonhuman primate population due to poor reproductive performance.

THE BEGINNINGS OF PRIMATES [PDF]

Evolution, 1968
When and from what mammalian group did primates originate? This question cannot yet be answered as accurately as students of Cretaceous and early Tertiary mammals would like. Although the evidence is still fragmentary and meager, however, the beginnings of primate radiation and their origin can be relatively well recognized.

Generation and functional characterization of tuft cells in non-human primate pancreatic ducts through organoid culture systems

Frontiers in Cell and Developmental Biology
The pancreatic duct plays a key role in collecting pancreatic juice, which is rich in digestive enzymes. The fluid flows unidirectionally into the duodenum, where it mixes with partially digested food to further facilitate digestion.

Analog VLSI-Based Modeling of the Primate Oculomotor System [PDF]

, 1998
One way to understand a neurobiological system is by building a simulacrum that replicates its behavior in real time using similar constraints. Analog very large-scale integrated (VLSI) electronic circuit technology provides such an enabling technology ...

Localization of multiple pleiotropic genes for lipoprotein metabolism in baboons[S]

Journal of Lipid Research, 2009
We employed a novel approach to identify the key loci that harbor genes influencing lipoprotein metabolism in approximately 2,000 pedigreed baboons fed various diets differing in levels of fat and cholesterol.

Primate modularity and evolution: first anatomical network analysis of primate head and neck musculoskeletal system [PDF]

, 2018
Network theory is increasingly being used to study morphological modularity and integration. Anatomical network analysis (AnNA) is a framework for quantitatively characterizing the topological organization of anatomical structures and providing an ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Primates chunk simultaneously-presented memoranda

Frontiers in Behavioral Neuroscience, 2022
Though much research has characterized both the behavior and electrophysiology of spatial memory for single targets in non-human primates, we know much less about how multiple memoranda are handled. Multiple memoranda may interact in the brain, affecting

Differentiation of primate primordial germ cell-like cells following transplantation into the adult gonadal niche. [PDF]

, 2017
A major challenge in stem cell differentiation is the availability of bioassays to prove cell types generated in vitro are equivalent to cells in vivo. In the mouse, differentiation of primordial germ cell-like cells (PGCLCs) from pluripotent cells was ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
