Observation of a hybrid spin resonance.

A new type of spin depolarization resonance has been observed at the Brookhaven Alternating Gradient Synchrotron (AGS). This spin resonance is identified as a strong closed-orbit sideband around the dominant intrinsic spin resonance. The strength of the resonance was proportional to the 9th harmonic component of the horizontal closed orbit and proportional to the vertical betatron oscillation amplitude.

Dexamethasone treatment and fluid balance in preterm infants at risk for chronic lung disease.

Unlabelled: The influence of dexamethasone on diuresis in preterm infants has not been well studied. We examined 15 preterm infants at risk for chronic lung disease with gestational ages ranging from 26 to 29 wk (median 27.6 wk) and birthweights ranging from 700 to 1485 g (median 965 g).

Postnatal glucose kinetics in newborns of tightly controlled insulin-dependent diabetic mothers.

Infants of diabetic mothers are at risk of developing hypoglycemia postnatally. Strict control of blood glucose during pregnancy might result in adequate glucose homeostasis in the neonate. We followed 15 mother-infant pairs from the beginning of pregnancy until birth.
