Supaglutide alleviates hepatic steatosis in monkeys with spontaneous MASH.

Background: Glucagon-like peptide 1 (GLP-1) is an incretin hormone and plays an important role in regulating glucose homeostasis. GLP-1 has a short half-life due to degrading enzyme dipeptidyl peptidase-IV and rapid kidney clearance, which limits its clinical application as a therapeutic agent. We demonstrated previously that supaglutide, a novel long-acting GLP-1 analog, exerted hypoglycemic, hypolipidemic, and weight loss effects in type 2 diabetic db/db mice, DIO mice, and diabetic monkeys.

Description of a Nonhuman Primate Model of Retinal Ischemia/Reperfusion Injury.

Purpose: To establish an inducible model of retinal ischemia/reperfusion injury (RI/RI) in nonhuman primates (NHPs) to improve our understanding of the disease conditions and evaluate treatment interventions in humans.

Methods: We cannulated the right eye of rhesus macaques with a needle attached to a normal saline solution reservoir at up to 1.9 m above the eye level that resulted in high intraocular pressure of over 100 mm Hg for 90 minutes.

Integrated network pharmacology and metabolomics to reveal the mechanism of QiShenYiQi Dripping Pills (T101) against cardiac structural and functional abnormalities.

Heart failure (HF), the final stage of cardiovascular diseases, is a clinical syndrome of cardiac structural or functional abnormalities. QiShenYiQi Dripping Pills (T101), short for QSYQ (T101), showed effectiveness and safety in the treatment of HF according to modern pharmacological research and clinical studies, but the mechanism remains unclear. This study aims to clarify the mechanism of QSYQ (T101) in treating heart failure through the analysis to critical biomarkers, targets and pathways.

Intra-abdominal vas deferens cyst in a laboratory rhesus macaque (Macaca mulatta).

A 21-year-old male rhesus macaque presented with abdominal enlargement. The clinical, magnetic resonance imaging, and computerized tomography findings confirmed a large mass occupying the entire abdomen. The mass was surgically removed, and histopathology confirmed a vas deferens cyst.

A new non-human primate model of desiccating stress-induced dry eye disease.

Dry eye disease (DED), a multifactorial ocular surface disease, is estimated to affect up to 34% of individuals over 50 years old. Although numerous animal models, including rodents and rabbits, have been developed to mimic the pathophysiologic mechanisms involved in dry eye, there is a lack of non-human primate (NHP) models, critical for translational drug studies. Here, we developed a novel desiccating stress-induced dry eye disease model using Rhesus macaque monkeys.

Development of Primary Open Angle Glaucoma-Like Features in a Rhesus Macaque Colony From Southern China.

Purpose: To describe the ocular phenotype of spontaneous glaucoma in a non-human primate colony.

Methods: In total, 722 Rhesus macaque monkeys aged 10 to 25 years underwent optical coherence tomography (OCT), fundus photography (FP), and intraocular pressure (IOP) measurements. Monkeys with baseline cup-to-disc ratio (CDR) <0.
