1. Saimiri sciureus has been infected with yellow fever virus, both by the inoculation of infectious blood and by the bites of infective mosquitoes. Some of the monkeys have died, showing lesions, including hepatic necrosis, suggesting yellow fever as seen in human beings and in rhesus monkeys. Virus has been transferred back to M. rhesus from infected Saimiri both by blood inoculation and by m...
Motor Stereotypic Behaviors in Zoo Rhesus Monkeys: a Case Study of the Central Zoo, Kathmandu, Nepal
Motor stereotypic behaviors (MSBs) are a kind of repetitive performed by stressed animals and more common in captivity. This study aimed to assess whether the MSB captive rhesus monkeys varies between males females, with extent visitor-monkey interactions. A group six (two adult four females; among two were rescued from wild captive-born) housed Central Zoo, Kathmandu Nepal sampled study. Behav...
BACKGROUND Atherosclerosis is one of the main risk factors cause acute cerebral-cardio vascular diseases. It's of great significance to establish an atherosclerosis animal model that can mimic the characteristics and nature course of human patients. Therefore, a rhesus monkey model was induced by high-fat diet to monitor their lipid profile and intima-media thickness (IMT) of artery walls and s...
Rhesus monkeys (Macaca mulata) were subjected to a place finding task in a rectangular room perfectly homogeneous and without distinctive featural information. Results of Experiment 1 show that monkeys rely on the large-scale geometry of the room to retrieve a food reward. Experiments 2 and 3 indicate that subjects use also nongeometric information (colored wall) to reorient. Data of Experiment...
Caloric restriction (CR) slows aging in many species and protects some animals from age-related hearing loss (ARHL), but the effect on humans is not yet known. Because rhesus monkeys are long-lived primates that are phylogenically closer to humans than other research animals are, they provide a better model for studying the effects of CR in aging and ARHL. Subjects were from the pool of 55 rhes...
OBJECTIVE To test if transdermal progesterone (P) confers coronary vascular protection in surgically menopausal preatherosclerotic rhesus monkeys. METHODS AND RESULTS Ovariectomized rhesus monkeys fed an atherogenic diet (AD) for 19 months were treated with an investigational transdermal P cream (n=7) or identical placebo cream (n=5) for 4 weeks. Aorta and carotids showed fatty streaks and Oi...
The objective of this study was to set up a rhesus monkey model of polycystic ovary syndrome (PCOS), which is globally prevalent among reproductive-aged human women, and to understand the reproductive traits of PCOS female monkeys. Six adult female rhesus monkeys aged 6-10 a, were divided into a PCOS group and a control group. The PCOS group were given two cycles of subcutaneous injections of p...
Clinical and serological responses investigated in rhesus and cynomolgus monkeys infected with either Bunyamwera or Germiston viruses were generally minimal or absent. A febrile reaction occurred in one of eight monkeys, and another monkey died unexplainably among those given Bunyamwera virus. All monkeys infected with Germiston virus by subcutaneous, intravenous, or intracerebral routes develo...
The relationships between peak velocity and amplitude of Edinger-Westphal (EW) stimulated accommodation and disaccommodation were investigated in anesthetized, middle-aged rhesus monkeys. Accommodative responses were recorded at 30Hz with infrared photorefraction. Peak velocity of accommodation and disaccommodation increased linearly with stimulus amplitude. Peak velocities of accommodation con...
Zika virus (ZIKV) is responsible for a major ongoing epidemic in the Americas and has been causally associated with fetal microcephaly. The development of a safe and effective ZIKV vaccine is therefore an urgent global health priority. Here we demonstrate that three different vaccine platforms protect against ZIKV challenge in rhesus monkeys. A purified inactivated virus vaccine induced ZIKV-sp...
