This study identified a compound heterozygous mutation in a hairless rhesus macaque, which was associated with skin abnormalities similar to those in hairless mice and humans with APL.

The researchers reported that alopecia is common in Japanese macaques, particularly adult females, and varies seasonally and between different populations, with a new scoring system proposed for monitoring.

This study found that the hair cortisol measurement procedure was reliable, unaffected by the choice of tubes, and that hair cortisol concentration correlated moderately with the number of intense aggressions experienced.

This study found that stress is likely the main cause of symmetrical alopecia in Formosan macaques, with higher stress hormone levels observed in affected individuals.

This study observed that hair loss in captive rhesus macaques varies with season, sex, and housing conditions, and is significantly correlated with HPA axis activity as indicated by faecal cortisol metabolites.

In this study, the isotopic fractionation between tissues and diets of captive Japanese macaques was quantified, particularly noting hair's response to diet changes in controlled conditions, but these findings underscore the complexity of reconstructing long-term dietary history.

In this study, pair housing of rhesus macaques after intrafacility transfer reduced some undesirable behaviors and diarrhea compared to single housing, although no cortisol level differences were observed.

This study found that female rhesus macaques who gained hair showed a significant reduction in hair cortisol concentrations, suggesting a connection between hair regrowth and stress levels.

This study observed that the development of the pars intermedia in long-tailed macaques is closely associated with changes in skin pigmentation during pre- and postnatal periods through melanocyte-stimulating hormone and ACTH activity.

This study observed that minoxidil specifically increased DNA synthesis in hair follicle cells, suggesting its distinct mechanism of action in promoting hair growth compared to cyclosporin, which showed no direct proliferative effect on these cells.

This study found that human hair keratin genes contain a few simple sequence repeats, with one repeat in the exon of KRT31 and additional repeats in introns, varying in length compared to their orthologues.

This study developed and validated a method for extracting cortisol from human and animal hair, suggesting its potential as a biomarker for assessing chronic stress exposure.

This article reviews the development and challenges of skin penetration enhancers, highlighting their limitations in compatibility and safety, and reports no new clinical findings.

This study highlights the importance of understanding the biology and social behavior of Old World monkeys in biomedical research, noting that improper housing can lead to stress-related behaviors that may impact research outcomes.

This study explored using large language models to automatically identify monkeypox cases from electronic medical records, finding that models based on DeepSeek features performed better than traditional methods, with logistic regression showing high accuracy in detecting key symptoms like fever and rash.

This paper discusses two preclinical models for studying alopecia areata and finds that testing new therapeutic agents should involve both the C3H/HeJ mouse model and the humanized mouse model for comprehensive insights.

This study discovered two new species of mites in the hair follicles of squirrel monkeys from South America, potentially causing follicle damage due to secondary infection.

This report describes a Sapajus nigritus investigated for multiparasitism after rescue from illegal home possession, highlighting public health and biodiversity conservation concerns related to human-primate proximity.

This review details the development and genetic background of senescence-accelerated mouse strains, provides a comprehensive examination of their phenotypes, and highlights their importance for aging research, but reports no new experimental results.

This study describes unique anatomical characteristics of the skin and hair structures in the silver marmoset, including features such as thin epidermis, specialized nerve end-organs, and distinctive gland compositions.

This study demonstrated that high oral doses of finasteride caused external genital abnormalities in male rhesus monkey fetuses, but intravenous doses did not lead to abnormalities.

In this study, zinc toxicosis in infant baboons was attributed to excessive environmental exposure, highlighting the importance of cage design in captivity and potential use of baboons as a developmental model.

This study found that high doses of TCB caused severe toxicity in cotton top marmoset monkeys, with clinical and histological changes similar to those in humans and other primates exposed to PCBs.

This review compares various rodent models that reflect aspects of psoriasis with human psoriasis and potential applications for research, reporting no new clinical findings.

This study developed a novel Hairless Rag2/Jak3 KO mouse model, which provides superior optical properties and thinner skin compared to existing models, enhancing its utility for noninvasive tumor monitoring and evaluation of anticancer therapies.

This review highlights the limitations of mouse models in human hair loss research and emphasizes the potential of using human cell bioengineered models and artificial intelligence for future advancements, but reports no new clinical results.
