Evolution of the vertebrate cytosolic malate dehydrogenase gene family: duplication and divergence in actinopterygian fish.

A general correlation between neural expression and negative charge in isozymes suggests charge represents an adaptation to the neural environment. Interestingly, a notable exception exists in teleost fish. Two cytosolic malate dehydrogenase (MDH) isozymes have different spatial expression patterns in certain fishes: one is expressed in all tissues and the second is expressed primarily in the eye and skeletal muscle.

Cocaine exposure in a term neonate. Necrotizing enterocolitis as a complication.

Cocaine use has increased dramatically in the past several years, and multiple medical complications associated with its use have been reported in adults, including bowel infarction and colitis. Maternal use of cocaine during pregnancy has been associated with complications in the fetus and newborn infant, including spontaneous abortions, preterm labor, cerebral infarctions, seizures, renal anomalies, and neurobehavioral and neurophysiologic abnormalities. This paper presents a case of necrotizing enterocolitis at birth in a term newborn exposed to cocaine antenatally.

Fetal pulmonary maturity: relationship between optical density (650 nm) to the lecithin/sphingomyelin ratio and phosphatidylglycerol in amniotic fluid.

An optical density value greater than or equal to 0.15 at A650 n m of amniotic fluid obtained through transabdominal amniocentesis from a high risk obstetrical population, which excluded diabetes mellitus, isoimmunization, and amniotic fluid infection, correlated 98.6% with a mature lecithin to sphingomyelin ratio (L/S) greater than or equal to 2.
