Biomechanics and Evolution of the Primate Tongue

open access: yesEvolutionary 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

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

open access: yesJournal 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.).

Pediatric NIH Workshop: Session III—Specialties and Complexities of Juvenile NHP Models for HIV Prevention Research

open access: yesJournal of Medical Primatology, Volume 55, Issue 3, June 2026.
ABSTRACT Nonhuman primates (NHPs) have emerged as an indispensable model for studying HIV pathogenesis, vaccines, and therapies. The development of chimeric Simian/Human immunodeficiency viruses (SHIVs) has been constructed by inserting HIV‐1 Env into the SIV (usually SIVmac239) backbone, and these have proved essential for evaluating HIV neutralizing ...

Visual Evoked Potentials to Light Flashes in Captive Rhesus Monkeys: A Study Reflecting Cerebral Cortical Activity and Brain Maturation [PDF]

open access: yesPakistan Veterinary Journal, 2014
Visual evoked potentials (VEPs) are useful electrophysiological diagnostic tools for evaluating retinal response of the visual cortex and detecting its functional integrity in humans and animals. To analyze the VEPs and physiologic response of the visual

Genetic Estimates of Relatedness: Established Practices and New Opportunities Through Low Coverage Whole‐Genome Sequencing

open access: yesMolecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT Identifying close relatives in wild animal populations is fundamental across many research fields. Genetic estimates of relatedness have expanded rapidly in recent decades, drawing on a range of genetic data types. Here, we review their use and outline opportunities for future studies by combining two complementary approaches.

Disparate Tuberculosis Disease Development in Macaque Species Is Associated With Innate Immunity

open access: yesFrontiers in Immunology, 2019
While tuberculosis continues to afflict mankind, the immunological mechanisms underlying TB disease development are still incompletely understood. Advanced preclinical models for TB research include both rhesus and cynomolgus macaques (Macaca mulatta and

Alzheimer's Abeta vaccination of rhesus monkeys (Macaca mulatta).

open access: yes, 2004
Recent preliminary data suggest that vaccination with Alzheimer's Abeta might reduce senile plaque load and stabilize cognitive decline in human Alzheimer's disease. To examine the mechanisms and consequences of anti-Abeta-antibody formation in a species
