Two doses of phenobarbital were given daily for 2 weeks to infant rats fed by intragastric cannulas. The larger dose (60 milligrams per kilogram of body weight) resulted in decreased spontaneous activity and increased responses to novel stimuli. The smaller dose (15 milligrams per kilogram) resulted in increased spontaneous activity and also an increase of(More)
Neonatal Long-Evans hooded rat pups were assigned to one of three groups: 1) pups normally reared, 2) pups implanted with intragastric cannulas and artificially reared with a common milk replacement formula, 3) pups implanted with intragastric cannulas and artificially reared with a protein-enriched milk formula. Daily body weights were recorded, as were(More)
Although clinical coronary heart disease and many cardiovascular risk factors are well known to aggregate within families, the heritability of carotid artery intima-media thickness (IMT) is less well documented. We report IMT heritability estimates in Mexican American, Salvadoran American, or Guatemalan American (all referred to as Latino) families(More)
Binding sites for [3H]vasopressin were identified in brains of neonatal (days 0-23) and adult (90 day) Long-Evans and Brattleboro rats, using a technique of in vitro receptor autoradiography. Results indicate that the regional distribution of binding sites for [3H]vasopressin in the brain changes markedly during postnatal development. Binding sites in the(More)
Previous studies have shown that damage induced to fungiform papillae of the anterior tongue at postnatal day 2 (P2) alters both pre- and postsynaptic development of gustatory recipient zones within the rostral nucleus of the solitary tract (NST). The present study was conducted to determine whether or not artificial rearing (AR) manipulations, which reduce(More)
Hydroxyapatite (HA) coatings have been used to improve implant fixation by promoting bone formation around the prosthesis. A macrophage response to HA particulates has been noted around loosened HA-coated prostheses. As biomaterial wear particle-associated macrophages are known to be capable of differentiating into osteoclasts that are capable of bone(More)
1. The acquisition of developmental milestones and maturational motor reflexes were compared in three rat strains (culled to 8 pups/litter), F344, Buff and SD. 2. Open field behavior on postnatal day 21 was scored for locomotor activity, rears and center entries. 3. F344 rats, which model ADHD, were the slowest of the three strains in acquiring a number of(More)
BACKGROUND The clustering of hypertension, insulin resistance, and obesity remains unexplained. We tested for genetic and nongenetic influences on the association among these traits in Hispanic families with hypertension. METHODS AND RESULTS Blood pressure and body mass index (BMI) were measured in 331 members of 73 Hispanic families in which an index(More)
