An example of a rare, highly aggressive malignant intranasal neoplasm in a male Bonnet macaque is presented. The tumor invaded the bony orbit, distorted the position of the globe, and metastasized to regional lymph nodes and lungs. Histologically the tumor was composed of both mesenchymal and
The main purpose of this study was to determine whether exposures to ambient levels of ozone induced changes in the carbohydrate content in the anterior nasal cavity of bonnet monkey. Monkeys were exposed to 0.00. 0.15, or 0.30 ppm of ozone for 6 or 90 days, 8 hours/day. Monkeys treated for 90 days
BACKGROUND
A 10-year-old, female bonnet monkey (Macaca radiata) showed abnormal menstrual cycle length with heavy menstrual bleeding for 6-8 days.
METHODS
Uterine ultrasound and histological examinations of endometrium by endometrial biopsy.
RESULTS
An ultrasound examination of the uterine cavity
The purpose of the present study was to characterize ultrastructurally the nonolfactory nasal epithelium of a nonhuman primate, the bonnet monkey. Nasal cavities from eight subadult bonnet monkeys were processed for light microscopy, and scanning and transmission electron microscopy. Nonolfactory
Ultrasound is a powerful, low-cost, non-invasive medical tool used by laboratory animal veterinarians for diagnostic imaging. Sonohysterography and transvaginal ultrasound are frequently used to assess uterine anomalies in women presenting with abnormal uterine bleeding (AUB). In the present study,
Inhaled irritants induce secretory cell hyperplasia in nasal epithelium of animals. To characterize this response histochemically it is first important to know the histochemical character and distribution of epithelial mucosubstance in the normal nasal cavity. An automated image analyzing method was
Despite the absorption of inhaled oxidant gases by the nasal cavity, little effort has been made to characterize the effects of these oxidants on the nasal mucosa. This study defines the effects of ambient concentrations of ozone on the character and amount of mucosubstances in epithelium of nasal
Explicit solvent molecular dynamics simulations of a macromolecule are slow as the number of solvent atoms considered typically increases by order of magnitude. Implicit methods introduce surface-dependent corrections to the force field, gaining speed at the expense of accuracy. Properties such as
Laboratory animal regulations provide little guidance regarding duration of nonsurvival surgery requiring aseptic technique. We hypothesized that swine would experience no sepsis during nonsurvival cardiothoracic surgery accomplished by using clean technique and lasting 8 h or less. Incision sites
Human amniotic epithelial cells (HAEC) possess certain properties similar to that of neural and glial cells. In the present work, the potential of HAEC as stem cells for spinal cord injury repair was tested. HAEC obtained from human placenta were labeled with
