Profiling immune repertoires by high throughput sequencing enhances our understanding of immune system complexity and immune-related diseases in humans. Previously, cloning and Sanger sequencing identified limited numbers of T cell receptor (TCR) nucleotide sequences in rhesus monkeys, thus their full immune repertoire is unknown. We applied multiplex PCR and Illumina high throughput sequencing...

The value of cynomolgus and rhesus monkeys to predict human pharmacokinetic parameters has been well established in recent years. However, practical limitations on cost and accessibility can often be a deterrent to obtain data in these valuable species, and the characterization of the predictive power of other nonhuman primates would be useful. Therefore, the present investigation was designed ...

A dosage equal to or greater than approximately 3.4 Dex (decimal exponent, log(10)) weanling mouse intracerebral 50% lethal dose (LD(50)) was sufficient to elicit a yellow fever antibody response, as determined by the plaque neutralization (PN) test, in better than 90% of vaccinated rhesus monkeys. Lower dosages were progressively less effective in terms of PN titers and the PN and hemagglutina...

The present study examined working memory for what, where, and when information in rhesus monkeys (Macaca mulatta) using a computerized task. In Experiment 1, monkeys completed three delayed matching-to-sample (DMTS) tasks: (1) identity DMTS, (2) spatial DMTS, and (3) temporal DMTS. In Experiment 2, the identity and spatial tasks were combined so that monkeys had to report both what and where i...

The resolution of growing conflict between monkey and man requires quantitative data on the nature and context of man-monkey agonistic (aggressive-submissive) interactions particularly in the urban areas. The ethological approach was followed to study the effect of habitat, species, and season on agonistic interactions between humans and monkeys in the city of Shimla. Three way ANOVA revealed t...

Adults and children have differences in their susceptibility to schistosomiasis. The relative influences of age-dependent innate resistance and acquired immunity in the differences between susceptibility to schistosomiasis are difficult to assess in humans. Therefore, we exposed juvenile and adult female rhesus monkeys to primary infection with Schistosoma mansoni. In contrast to the adult anim...

Histological lesions in the lungs of rhesus monkeys (Macaca mulatta) related with Pneumonyssus simicola were evidenced. The most prominent pathologic alterations included numerous thin-walled cysts 1-5mm diameter scattered throughout the lungs, bronchiolitis, peribronchiolitis where the mites were found associated with pigmented and non-pigmented materials. Our study included data from 347 rhes...

The immunogenicity and efficacy of an inactivated whole SIVmac (32H) preparation adjuvanted with muramyl dipeptide (SIV-MDP) and a gp120-enriched SIVmac (32H) ISCOM preparation (SIV-ISCOM), were compared by immunizing four rhesus macaques (Macaca mulatta) four times with SIV-MDP and four others in the same way with SIV-ISCOM. Two monkeys immunized with whole inactivated measles virus (MV) adjuv...

Same/different abstract-concept learning experiments were conducted with two primate species and three avian by progressively increasing the size of training stimulus set distinctly different pictures from eight to 1,024 pictures. These same/different trained presented simultaneously. Transfer tests same employed interspersed trials novel assess level correct performance on very first time subj...

objective: currently, cellular transplantation for spinal cord injuries (sci) is the subject of numerous preclinical studies. among the many cell types in the adult brain, there is a unique subpopulation of neural stem cells (nsc) that can self-renew and differentiate into neurons. the study aims, therefore, to explore the efficacy of adult monkey nsc (mnsc) in a primate sci model. materials an...
