The MacBrain Resource Center (MBRC) rhesus macaque embryonic brain histology datasets

Journal of Anatomy, EarlyView.
We introduce the MacBrain Resource Center (MBRC) Collections of rhesus macaque embryonic brain tissue. Here, we illustrate histo‐ and immunohistology from our dynamically growing Collection 6, which currently contains >10,000 zoomable and downloadable images from n = 14 male and female embryos from early to late in gestation.

Pharmacokinetics of Long‐Acting Ampicillin and Its Impact on the Gut Microbiome and Resistome in Rhesus Macaques (Macaca mulatta)

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT Injectable antimicrobials with documented prolonged dosing intervals (> 48 h) for use in rhesus macaques are sparse. The objective of our study was to assess the pharmacokinetics, urine excretion, and effects on gut microbiome and resistome of intramuscular administered long‐acting formulation of ampicillin (Albipen LA) in macaques.

Pharmacokinetics of 2 mg/kg Bupivacaine in a Rectus Abdominis Sheath Block in Horses

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT Administering large volumes of bupivacaine in the rectus abdominis sheath (RAS) block in horses could cause local anesthetic toxicity. This study aimed to evaluate the pharmacokinetics of 2 mg/kg bupivacaine in RAS blocks and the associated toxicity risk.

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

Biological Reviews, Volume 101, Issue 3, Page 1463-1478, June 2026.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Aggression heuristics underlie animal dominance hierarchies and provide evidence of group-level social information

, 2020
Members of a social species need to make appropriate decisions about who, how, and when to interact with others in their group. However, it has been difficult for researchers to detect the inputs to these decisions and, in particular, how much ...

Biomechanics and Evolution of the Primate Tongue

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 2, June 2026.
ABSTRACT Primate tongue morphology and function are critical to understanding the evolution of feeding, swallowing, and vocalization. In this paper, we examine the primate tongue as a muscular hydrostat with regionally specialized neuromuscular compartments. We integrate anatomical, kinematic, and biomechanical modeling approaches to analyze how muscle

Les macaques de Tonkéan (Macaca tonkeana) et les macaques rhésus (Macaca mulatta) discriminent-ils les mêmes indices sociaux d’un partenaire humain ?

Revue de Primatologie, 2014
Les études portant sur les précurseurs de la Théorie de l’Esprit tels que la compréhension des états attentionnels d’autrui ont été largement menées chez les grands singes et ont rapporté des résultats discordants.

An Adaptive Threshold in Mammalian Neocortical Evolution

, 2013
Expansion of the neocortex is a hallmark of human evolution. However, it remains an open question what adaptive mechanisms facilitated its expansion.

Validation of Immunoassays for Total Thyroxine and Free Thyroxine and Age and Sex‐Related Variation in Thyroid Hormone Serum Concentrations in Orangutans (Pongo sp.)

Journal of Medical Primatology, Volume 55, Issue 3, June 2026.
ABSTRACT Background Thyroid disease is reported in orangutans, but to properly diagnose and manage these disorders, reference intervals for circulating thyroid hormones are needed. Methods Commercial immunoassay kits for total thyroxine (TT4) and free thyroxine (FT4) were validated for use in orangutans (Pongo spp.).

Chronic Colitis, Juvenile Macaca mulatta [PDF]

, 1993
The general body condition of affected animals reflects emaciation and dehydration. These animals have a moderately dilated colon filled with brown or green fluid feces. The colonic mucosa is diffusely thickened and granular (Fig. 90). Areas of the colonic mucosa may have a rugose appearance and small erosions or microulcers may be evident.
