Social stability influences the association between adrenal responsiveness and hair cortisol concentrations in rhesus macaques

Autor: John P. Capitanio, Melinda A. Novak, Jerrold S. Meyer, Jessica J. Vandeleest, Amanda F. Hamel, Brenda McCowan, Sally P. Mendoza

Hair cortisol concentrations are increasingly being used in both humans and nonhuman animals as a biomarker of chronic stress. However, many details regarding how hair cortisol concentrations relate to the dynamic activity and regulation of the HPA a

Rhesus macaques (Macaca mulatta) displaying self-injurious behavior show more sleep disruption than controls

Autor: Melinda A. Novak, Amanda F. Hamel, Lauren L. Stanwicks

Self-injurious behavior (SIB) is a pathology observed in both humans and animals. In humans, SIB has been linked to various mental health conditions that are also associated with significant sleep disruption. In rhesus macaques, SIB consists of self-

Relationships between affiliative social behavior and hair cortisol concentrations in semi-free ranging rhesus monkeys

Autor: Jerrold S. Meyer, Amanda M. Dettmer, Lauren J. Wooddell, Amanda F. Hamel, Stefano S. K. Kaburu, Kristen L. Byers, Stephen J. Suomi, Ashley M. Murphy

Sociality is a fundamental aspect of human behavior and health. One benefit of affiliative social relationships is reduced short-term levels of glucocorticoids (GCs), which are indicative of physiological stress. Less is known, however, about chronic

Fatty acid supplements improve hair coat condition in rhesus macaques

Autor: Melinda A. Novak, Amanda F. Hamel, Mark T. Menard

Publikováno v: Journal of medical primatology. 46(5)

As captive rhesus macaques often exhibit hair loss, alopecia was quantified and behavior was recorded before, during, and after fatty acid supplementation in six macaques. Fatty acid treatment was associated with a decrease in alopecia and in self-gr

Models of Stress in Nonhuman Primates and Their Relevance for Human Psychopathology and Endocrine Dysfunction

Autor: Jerrold S. Meyer, Amanda F. Hamel

Publikováno v: ILAR Journal. 55:347-360

Stressful life events have been linked to the onset of severe psychopathology and endocrine dysfunction in many patients. Moreover, vulnerability to the later development of such disorders can be increased by stress or adversity during development (e

Hair loss and hypothalamic-pituitary-adrenocortical axis activity in captive rhesus macaques (Macaca mulatta)

Autor: Melinda A, Novak, Amanda F, Hamel, Kris, Coleman, Corrine K, Lutz, Julie, Worlein, Mark, Menard, Amy, Ryan, Kendra, Rosenberg, Jerrold S, Meyer

Publikováno v: Journal of the American Association for Laboratory Animal Science : JAALAS. 53(3)

Hair loss is a common problem in captive macaque colonies. A potential factor is the possible influence of stressful environments in the development of hair loss. We examined the relationship between hair loss and chronic hypothalamic–pituitary–a

Extraction and Analysis of Cortisol from Human and Monkey Hair

Autor: Melinda A. Novak, Kendra Rosenberg, Jerrold S. Meyer, Amanda F. Hamel

Publikováno v: Journal of Visualized Experiments.

The stress hormone cortisol (CORT) is slowly incorporated into the growing hair shaft of humans, nonhuman primates, and other mammals. We developed and validated a method for CORT extraction and analysis from rhesus monkey hair and subsequently adapt

Stress, the HPA axis, and nonhuman primate well-being: A review

Autor: Melinda A. Novak, Jerrold S. Meyer, Brian J. Kelly, Amanda F. Hamel, Amanda M. Dettmer

Publikováno v: Applied animal behaviour science. 143(2-4)

Numerous stressors are routinely encountered by wild-living primates (e.g., food scarcity, predation, aggressive interactions, and parasitism). Although many of these stressors are eliminated in laboratory environments, other stressors may be present
