Qualitative Behavioural Assessment of bonobo emotional expressivity across observer groups and zoo housing environments

Animal Welfare
Human evaluation of animal emotional expressivity can inform animal welfare. Qualitative Behavioural Assessment (QBA) has been applied to domesticated and some non-domesticated animals, but its use in primates is limited despite their emotional ...

Metabolic changes to GLUT-4 levels in urban Chacma baboons on the Cape Peninsula: raiding their way to type 2 diabetes? [PDF]

, 2013
The Chacma baboons (Papio ursinus) of the Cape Peninsula are established raiders of human food, leading to widespread conflict between this intelligent, adaptable species and humans.

Dose‐dependent pathogenicity and inflammatory imbalance in severely immunodeficient mice infected with mpox virus

Animal Models and Experimental Medicine, EarlyView.
This study establishes an NPG (NOD.Cg‐Prkdcscid Il2rgtm1/Vst) mouse model for severe monkeypox virus infection in immunocompromised hosts, demonstrating dose‐dependent disease severity and revealing that unbalanced pro‐inflammatory cytokine release drives pathogenesis, providing insights for therapeutic interventions. Abstract The global spread of mpox

Astrocytic Mitochondria Transplantation Rescues Neuron Loss and Dendritic Injuries in Acute Cerebral Ischemic Stroke Mouse Model by Flexibly Regulating Mitochondria Dynamics

Annals of Neurology, EarlyView.
Objective Cerebral ischemic stroke causes neuronal oxygen/energy deprivation, disrupting mitochondrial function including reduced membrane potential and bioenergetics, exacerbating neuronal injury. Mitochondrial defects are, therefore, a central neuropathological node and potential therapeutic target.

Non-human primate model of long-COVID identifies immune associates of hyperglycemia

Nature Communications
Hyperglycemia, and exacerbation of pre-existing deficits in glucose metabolism, are manifestations of the post-acute sequelae of SARS-CoV-2. Our understanding of metabolic decline after acute COVID-19 remains unclear due to the lack of animal models ...

Histopathological characterization of nephritides in the brown capuchin monkey, Cebus apella (Primates: Cebidae)

Revista de Biología Tropical, 2000
The renal lesions are of special importance in the captive primates. The most commonly pathologies are: pyelonephritis, nephrocalcinosis, glomerulonephritis, congenital malformations, hydronephrosis and functional diseases.

In vitro matured oocytes have a higher developmental potential than in vivo matured oocytes after hormonal ovarian stimulation in Callithrix jacchus

Journal of Ovarian Research
Background The common marmoset, Callithrix jacchus, is an invaluable model in biomedical research. Its use includes genetic engineering applications, which require manipulations of oocytes and production of embryos in vitro.

Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

The Anatomical Record, EarlyView.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

The Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.
