The locus coeruleus (LC) of the rat was lesioned by microinjection of selective neurotoxins into the brainstem. 6-Hydroxydopamine (6-OHDA), 3 micrograms/microliter, given unilaterally at two sites 0.6 mm apart on the rostro-caudal axis of the LC, was used to lesion catecholamine-containing neuronal elements. Ibotenic acid, 2.5 micrograms/0.5 microliters,(More)
This article explores the relationship between time preferences, economic incentives and body mass index (BMI). We provide evidence of an interaction effect between time preference and food prices, with cheaper food leading to the largest weight gains among those exhibiting the most impatience. The interaction of changing economic incentives with(More)
Angiotensin-(1-7) (Ang-(1-7)) is reported to be equipotent with angiotensin II (AII) in producing some central biological effects but the receptors responsible for these actions have not been defined. Three classes of receptor have been proposed: AT1, AT2, and a putative Ang-(1-7) selective receptor. This study specifically evaluates Ang-(1-7) competition(More)
Previous studies have used new angiotensin II (AII) receptor subtype selective compounds to localize AII receptor subtypes within discrete rat brain nuclei. The purpose of this autoradiographic study was to extend these preliminary findings and provide a comprehensive analysis of AII binding sites in 22 rat brain nuclei and the anterior pituitary, to(More)
Vero cytotoxin-producing Escherichia coli O157 belonging to four phage types (PTs) caused 11 outbreaks of infection in England and Wales in 1995. Outbreak strains of different PTs were distinguishable by DNA-based methods. Pulsed-field gel electrophoresis best discriminated among strains belonging to the same PT, distinguishing six of the seven PT2 outbreak(More)
For epidemiologic investigations, the primary subdivision of Salmonella Typhi is vi-phage typing; 106 Vi-phage types are defined. For multidrug-resistant strains the most common types have been M1 (Pakistan) and E1 (India, Pakistan, Bangladesh, and the Arabian Gulf); a strain untypable with the Vi phages has been responsible for a major epidemic in(More)
Salmonella agona infections increased abruptly in England and Wales; isolates of S. agona from 41 patients with diarrheal illness were referred to the Laboratory of Enteric Pathogens of the Public Health Laboratory Service, compared with nine cases in the previous 12 months. Most isolates were from children under 10 years of age. Many of the cases were in(More)
The non-peptidic angiotensin II receptor subtype selective antagonists, DuP 753 and PD123177, were used to characterize angiotensin II receptor binding sites in the rat brain. Competitive receptor autoradiography with 125I-Sar1-Ile8 angiotensin II defined a regional distribution of binding sites that were sensitive to either DuP 753 (designated AII alpha(More)
Two angiotensin II receptor subtypes were distinguished in the rat brain using in vitro receptor autoradiography based on the differential effects of sulfhydryl reducing agents on 125I-sarcosine1,isoleucine8 angiotensin II binding in various brain nuclei. At several nuclei, e.g. the hypothalamus, circumventricular organs and the dorsal medulla,(More)
Previous work has reported that the distribution of AT(1) binding sites in the rabbit brain is similar to that in the rat, but AT(2) binding sites are confined to the septum and cerebellum of the rabbit brain. This receptor autoradiographic study was designed to enhance the detection of angiotensin II binding sites by using greater radioligand(More)
