Absence of the right wing of the ilium generated a compensatory scoliosis in rhesus monkey in captivity: diagnostic imaging and its alteration on the SEPNT.

Background: Congenital scoliosis (CS) is defined as lateral curvatures of the spine provoked by the anomalous development of the vertebral bodies. It is associated with neuromuscular anomalies, which can be genetic, caused by the compensation of discrepancies in the length of the extremities or intrarachidian anomalies.

Methods: This study was carried out in 2-year-old female, showed alterations in the gait, mainly in the hind limbs, a clumsy gait and a slight claudication in the right hindlimb.

Changes in blood parameters in rhesus monkeys (Macaca mulatta) during the first trimester of gestation.

Background: Regarding the good practice in the laboratory work, it is essential to have a broad spectrum of biochemical and hematological references in pregnant females to determine the health status of the colony.

Objective: To establish reference values to reveal changes in hematology and blood chemistry in pregnant rhesus monkeys (Macaca mulatta) in their first trimester of pregnancy.

Methods: Twenty-eight females in reproductive stage were used, divided into two groups: 14 pregnant macaques in their first trimester and 14 non-pregnant used as the control group.

Latencies obtained of the somatosensory evoked potentials of the median and tibial nerve in rhesus monkey undergoing intrauterine laminectomy to simulate myelomeningocele.

Background: Somatosensory evoked potentials (SSEP) have been described as excellent indicators of the degree of medullar injury in degenerative and metabolic diseases of the central nervous system (CNS). The prevalence of neural tube defects (NTD) is 6 cases/10,000 live newborns worldwide. It is thought that genetic as well as environmental factors contribute to the etiology of NTD.

Visuomotor functions and intelligence subsequent to strabismus treatment. Second phase.

Background: Strabismus has been related to different alterations of brain functions and learning in children. Early treatment for visuomotor functions may improve the executive areas of intelligence. We undertook this study to demonstrate changes of visuomotor function and intelligence in children after strabismus treatment.

Somatosensory evoked potentials of median and tibial nerves in rhesus monkeys (Macaca mulatta) under captivity: influence of ontogenic status in neonatal, infant, young, adult, and senile stages.

Background: Somatosensory evoked potentials (SEPs) constitute a useful neurophysiologic tool commonly used to assess the functionality and developmental degree of the nervous system.

Objective: To analyze somatosensory pathways of the Macaca mulatta species throughout different ontogenetic statuses.

Methods: Twenty non-human primates were divided into five age-dependant groups.
