RATIONALE Several lines of evidence have indicated that the central histaminergic system might be involved in learning and memory OBJECTIVES The aim of the present study was to ascertain the impact on memory processes of putative histaminergic-cholinergic interactions in the nucleus basalis magnocellularis (NBM) of the rat. METHODS The effects of(More)
The mnemonic performances of male and female rats were compared in an object recognition test. Females were still able to recognize a previously identified object after a 90-min between-trial interval, compared with only 60 min in the males. Because histamine (HA) involvement in memory processes has been strongly suggested, the effect of H3-HA autoreceptor(More)
The role of the histamine (HA) H3 receptor (estimated by binding of [3H]N-alpha-methyl HA in the brain cortex) in the response of male rats to four types of stress was evaluated: acute weak foot-shock stress (0.5 mA x 1 s x 5 times), acute intense foot-shock stress (1mA x 10 s x 5 times), acute restraint stress (60 min at 24 degrees C) and chronic variate(More)
Changes in the baseline and in the 40 mM K+-evoked release of histamine from hypothalamus slices were compared in male and female rats aged 2, 6, 12, 18, and 24 months. The baseline release declined in the 12-, 18-, and 24-month males. In contrast, the K+-evoked release remained constant in the males, but in the females it decreased in animals more than 2(More)
We report the first measurements of inclusive W and Z cross sections times leptonic branching ratios for pp collisions at square root[s]=1.96 TeV, based on their decays to electrons and muons. The data correspond to an integrated luminosity of 72 pb(-1) recorded with the CDF detector at the Fermilab Tevatron. We test e-mu universality in W decays, and we(More)
We report the results of a search for a W' boson produced in pp; collisions at a center-of-mass energy of 1.8 TeV using a 106 pb(-1) data sample recorded by the Collider Detector at Fermilab. We observe no significant excess of events above background for a W' boson decaying to a top and bottom quark pair. In a model where this boson would mediate(More)
5 Abstract The lifetimes of the B − and B 0 mesons are measured using the partially reconstructed semileptonic decays B → Dℓ − νX, where D is either a D 0 or D * + meson. The data were collected by the CDF detector at the Fermilab Tevatron collider during 1992-1995 and correspond to about 110 pb −1 of ¯ pp collisions at √ s = 1.8 TeV. We measure decay(More)
Since estradiol (E2) either increases or reduces the number of dopamine receptors in the corpus striatum of adult rats, depending on the dose and length of administration, the sensitivity of the two receptor subpopulations (D1 and D2) to E2 during ontogenesis was investigated. Rats of both sexes received either 10 micrograms/kg E2 for 3 days or 50(More)
