Effects of Early Daily Alcohol Exposure on Placental Function and Fetal Growth in a Rhesus Macaque Model
Lo et al., American Journal of Obstetrics and Gynecology. 2021.

In a rhesus macaque model for chronic prenatal alcohol exposure, daily consumption during early pregnancy significantly diminished placental perfusion at mid to late gestation and significantly decreased the oxygen supply to the fetal vasculature throughout pregnancy. These findings were associated with the presence of microscopic placental infarctions. Although placental adaptations may compensate for early environmental perturbations to fetal growth, placental blood flow and oxygenation were reduced, consistent with the evidence of placental ischemic injury that persisted throughout pregnancy.

MRI Characteristics of Japanese Macaque Encephalomyelitis (JME): Comparison to Human Diseases
Tagge et al., Journal of Neuroimaging. 2021.

Magnetic resonance imaging data (MRI) were obtained from 114 Japanese macaques, including 30 animals of both sexes that presented with neurological signs of Japanese macaque encephalomyelitis (JME). Quantitative estimates of blood-brain barrier permeability to gadolinium-based-contrast agent (GBCA) were obtained in acute, GBCA-enhancing lesions, and longitudinal imaging data were acquired for 15 JME animals. Intense, focal neuroinflammation was a key MRI finding in JME. Several features of JME compare directly to human inflammatory demyelinating diseases. The development and validation of noninvasive imaging biomarkers in JME provides the potential to improve diagnostic specificity and contribute to the understanding of human demyelinating diseases.
