Paternity testing for crab‐eating macaques and rhesus macaques using microsatellite markers

Animal Models and Experimental Medicine
Accurate macaque paternity identification is of great significance in various fields, yet relevant research remains scarce. Our study aimed to screen effective microsatellite markers for macaque paternity testing.

Previously undocumented regional variability in crab‐eating macaque skull sexual dimorphism and its implications for biological and morphometric studies

The Anatomical Record, EarlyView.
Abstract In a large sample of adult crab‐eating macaques, we quantified sexual dimorphism in size, shape, and covariance across the whole skull and among anatomical regions of the cranium and mandible. All regions showed significant mean sex differences, but the magnitude of size and shape dimorphism varied substantially.

The mechanism of labor in nonhuman primates: A look inside

The Anatomical Record, EarlyView.
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Intrinsic functional clustering of the macaque insular cortex

Frontiers in Integrative Neuroscience
The functional organization of the primate insula has been studied using a variety of techniques focussing on regional differences in either architecture, connectivity, or function.

Evolutionary morphology of the haplorhine hamate

The Anatomical Record, EarlyView.
Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.

Variable grouping patterns in primates: A test of the better competitor hypothesis in male Verreaux's sifaka (Propithecus verreauxi)

The Anatomical Record, EarlyView.
Abstract Intraspecific variation in social organization (IVSO) within primate populations can arise due to male mating competition. Verreaux's sifaka (Propithecus verreauxi) populations exhibit both single‐male and multi‐male groups, providing an opportunity to examine the relationship between male competitive ability and social organization.

Prediction of Human Serum Concentration–Time Profiles of Golimumab and Ustekinumab Using Pharmacokinetic Data From Common Marmosets With Assessment of Anti‐Drug Antibodies

Biopharmaceutics &Drug Disposition, EarlyView.
This study identified new optimal allometric scaling exponents for human PK prediction of monoclonal antibodies with linear PKs from marmoset PK data. In addition, immunogenicity in common marmosets was evaluated following the repeated dose of golimumab and ustekinumab, minimal anti‐drug antibodies were detected.

Construction and operation of a high-speed, high-precision eye tracker for tight stimulus synchronization and real-time gaze monitoring in human and animal subjects

Frontiers in Systems Neuroscience, 2016
Measurements of the fast and precise movements of the eye—critical to many vision, oculomotor, and animal behaviour studies—can be made non-invasively by video oculography.

Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Brain volumetric and microstructural correlates of executive and motor performance in aged rhesus monkeys

Frontiers in Aging Neuroscience, 2012
The aged rhesus macaque exhibits brain atrophy and behavioral deficits similar to normal aging in humans. Here we studied the association between cognitive and motor performance and anatomic and microstructural brain integrity measured with 3T magnetic ...
