Introduction: Amongst martian meteorites correlations between La/Yb values and initial Sr and Nd isotopic compositions indicate the presence of long-term incompatible element-enriched and-depleted reservoirs, and suggest that martian magmatism is characterized by mixing between these reservoirs [1-4]. Recent work [5] has suggested that oxygen fugacity (fO(More)
Introduction: Ureilites are ultramafic meteorites composed mainly of magnesian (mg#=76-95) olivine and pyroxene, with minor carbon-bearing phases and metal. Ureilite characteristics suggest that monomict ureilites are residues of partial melting on a carbona-ceous chondrite-like asteroidal parent body [1]. Basal-tic meteorites complementary to the monomict(More)
The effects of amphetamine (5-20 mg/kg) were studied 60 min after injection in mice aged 2, 3, 4 and 6 weeks postpartum. Exploratory behavior as indicated by the "head poke" test was depressed at all ages, but appeared to be relatively uncomplicated by other effects at the 5 mg/kg dose. At 4 and 6 weeks control females showed significantly greater activity(More)
We have examined the sleep profile of the Flinders Sensitive Line (FSL) of rats, which were selectively bred for supersensitive responsivity to an acetylcholinesterase inhibitor (DFP). These animals have an increased density of muscarinic receptors in striatum and hippocampus and display a number of behavioral and neuroendocrine characteristics that may(More)
The NMR relaxation times T'2, T2, and T1 were measured in isolated rat lungs as functions of external magnetic field B0, temperature, and lung inflation. The observed linear dependence on B0 of the tissue-induced free induction decay rate (T'2)-1 provides independent confirmation of the air/water interface model of the lung. Furthermore, measurements of the(More)
Introduction: Ureilites are fragments of the mantle of a small (~100 km radius) asteroid that underwent ~30% partial melting at depths corresponding to pressures in the range 30-125 bars [1,2]. The preservation of oxygen isotopic heterogeneity on the ureilite parent body (UPB), despite high-T igneous processing [1], suggests that melts were extracted very(More)
Previous Work: Many models for the petrogenesis of ureilites have assumed CC-like precursor material, as suggested by their O-isotopes (which point toward CV) and high C contents [1]. Although in detail the data do not show a clear link to any specific CC group [1], this remains the most reasonable assumption. Goodrich [2] examined chondritic silicate(More)

NWA 1500 ungrouped achondrite may be related to brachinite based on new oxygen isotope analyses using both SIMS and laser fluorination methods. We compare NWA 1500 with brachinites and ureilites and discuss their parent body processes.

Experiments were designed to distinguish between central and peripheral effects on temperature preference and body temperature of drugs injected intraperitoneally (IP) in infant mice ranging in age from 3 to 10 days postpartum. These compared a drug restricted to the periphery ("peripheral" drug) with a drug of similar action that reaches the central(More)
Thermoregulatory effects of the selective 5-HT2 antagonist pirenperone were studied 1 hr after IP injection in mice aged 1, 3, 5, 7 and 10 days postpartum. Compared with vehicle injected littermates, a dose of 0.16 mg/kg decreased temperature preference (T pref) on a thermal gradient at all ages. No significant effects were observed on body temperature (Tb)(More)
