Article Abstract
Video-based action recognition is becoming a vital tool in clinical research and neuroscientific study for disorder detection and prediction. However, action recognition currently used in non-human primate (NHP) research relies heavily on intense manual labor and lacks standardized assessment. In this work, we established two standard benchmark datasets of NHPs in the laboratory: MonkeyinLab (MiL), which includes 13 categories of actions and postures, and MiL2D, which includes sequences of two-dimensional (2D) skeleton features. Furthermore, based on recent methodological advances in deep learning and skeleton visualization, we introduced the MonkeyMonitorKit (MonKit) toolbox for automatic action recognition, posture estimation, and identification of fine motor activity in monkeys. Using the datasets and MonKit, we evaluated the daily behaviors of wild-type cynomolgus monkeys within their home cages and experimental environments and compared these observations with the behaviors exhibited by cynomolgus monkeys possessing mutations in the gene as a disease model of Rett syndrome (RTT). MonKit was used to assess motor function, stereotyped behaviors, and depressive phenotypes, with the outcomes compared with human manual detection. MonKit established consistent criteria for identifying behavior in NHPs with high accuracy and efficiency, thus providing a novel and comprehensive tool for assessing phenotypic behavior in monkeys.

Overexpression and gain-of-function mutations of c-Kit have been implicated in cancers including gastrointestinal stromal tumors (GIST), small cell lung cancer (SCLC), acute myeloid leukemia, and systematic mastocytosis. In clinics, small molecule c-Kit inhibitors often result in secondary c-Kit mutations or are ineffective despite c-Kit overexpression. We developed NN3201, a novel c-Kit targeting antibody-drug conjugate (ADC), via rational design to evaluate its anticancer activity in c-Kit-positive tumors, and preclinical pharmacologic profiles.

Background: A growing body of evidence from primate embryos as well as in vitro systems supports the notion that amnion and primordial germ cell (PGC) lineage progressing cells share a common precursor.
Results: To gain comprehensive transcriptomic insights into this critical but poorly understood precursor and its progeny, we examine the evolving transcriptome of a developing human pluripotent stem cell-derived model of amnion and PGC formation at the single cell level. This analysis reveals several continuous amniotic fate progressing states with state-specific markers.

Hydrolases in the eye play an important role in the metabolism of ophthalmic drugs, especially those administered locally to the eyes. With the growing interest in peptide-based therapeutics for treating eye disease, it has become increasingly important to characterize the enzymatic activities of ocular tissues against both small molecules and peptides to better understand their ocular metabolism. In this study, we characterized the activities of hydrolases, including carboxylesterase 1 and 2, arylacetamide deacetylase, paraoxonases, cytidine deaminase, fatty-acid amide hydrolase, and peptidases by incubating probe substrates in whole eye homogenates and vitreous humors from human donors and 3 preclinical species, including New Zealand White rabbits, Gottingen minipigs, and Cynomolgus monkeys.

Background: Drug bridging immunoassays are widely employed as the standard approach for detecting anti-drug antibodies (ADAs) in the development of new biological entities. A major challenge in these assays is mitigating target interference, particularly when the soluble target exists in dimeric forms, which can result in false positive signals and compromise assay specificity.
Research Design And Methods: We developed sensitive and robust ADA assays capable of overcoming target interference to detect antibodies against BI X in both cynomolgus monkey (cyno) plasma and human serum matrices.

Background: Mycobacterium tuberculosis (MTB) Ag85A has become a component of multiple new tuberculosis vaccines. It is necessary to evaluate the immunogenicity, biological distribution, and safety of ag85a plasmid DNA (pDNA) to lay the foundation for the design of new vaccines.
Method: Chronic toxicity test: cynomolgus monkeys were injected intramuscularly with different doses of ag85a pDNA, and the vaccine absorption kinetics, tissue distribution, and toxicity were observed.
