The transverse diameter of the cerebellum was measured with ultrasound in 265 normal fetuses ranging from 15 to 39 weeks gestational age and found to correlate closely with the biparietal diameter. The transverse diameter may be useful in estimating fetal age, particularly in breech presentation where extrinsic pressure may deform the skull and decrease the biparietal diameter. Failure to demonstrate the cerebellum could be a sign of Arnold-Chiari malformation or Dandy-Walker cyst.
Uric acid, blood urea nitrogen, glucose, total serum protein, cholesterol, triglyceride, calcium, magnesium, phosphorus, and chloride concentrations in the blood plus pH, bilirubin, ketone, blood, protein and glucose levels in the urine were determined for gray squirrels captured in Jacksonville, Florida. Significant differences were not noted for any of these values when compared by the age or sex of the animals, by breeding or lactation status, by month of capture, or by habitat type. Depressed blood glucose and elevated blood urea nitrogen levels were observed in squirrels with shock syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
