Previous electrophysiological studies suggested that the initiation of behavioral sensitization to cocaine and amphetamine involves a transient increase in AMPA receptor responsiveness in the ventral tegmental area (VTA). To test this, we used in vivo microdialysis to examine the effects of intra-VTA administration of AMPA (10 microm) and NMDA (100 microm)(More)
It has been demonstrated recently that antagonists of the tachykinin NK1 receptor, specifically CP-99,994 and GR203040, possess anti-emetic activity in a range of species. To optimise this activity, a series of analogues based around the structure of GR203040 have been synthesised and their affinity at the human tachykinin NK1 receptor determined. In(More)
We identify changes in the pelagic fish community of the tropical Pacific Ocean by comparing recent data collected by observers on longline fishing vessels with data from a 1950s scientific survey when industrial fishing commenced. A major shift in size composition and indices of species abundance and community biomass accompanied the start of fishing. The(More)
Our knowledge of large pelagic fi sh in the open ocean comes primarily from tagging and tracking experiments and from data collected from longline fi sh-ing vessels since the 1950s. Abundance indices for pelagic stocks are often derived from analyses that model catch as a function of factors such as year, area, and season. However, the amount of time that(More)
Two high affinity and selective NK1-receptor antagonists, GR203040 and GR205171, were labelled with 11C and used in a series of experiments in rhesus monkeys. The purpose of these studies was to evaluate the brain uptake pattern and to explore the potential use of these compounds as PET ligands to characterise NK1-receptor binding. Seventeen studies were(More)
We introduce a new method that uses generalized linear mixed models to infer the depth distribution of pelagic fishes. It uses existing data from research surveys and observers on commercial vessels to estimate changes in catchability when longline fishing gear is lengthened to access deeper water. We infer the depth distribution of catchability for 37 fish(More)
Pelagic longline fishers have continuously modified their gear and practices to improve fishing power or the catchability of target species, which has altered the relationship between catch rates and abundance. Advances in technology resulted in the introduction of many electronic devices to assist in navigation, communication, and finding target species.(More)

BACKGROUND Maintaining adequate supplies of anti-malarial medicines at the health facility level in rural sub-Saharan Africa is a major barrier to effective management of the disease. Lack of visibility of anti-malarial stock levels at the health facility level is an important contributor to this problem. METHODS A 21-week pilot study, 'SMS for Life', was(More)
Many preclinical studies in critical care medicine and related disciplines rely on hypothesis-driven research in mice. The underlying premise posits that mice sufficiently emulate numerous pathophysiologic alterations produced by trauma/sepsis and can serve as an experimental platform for answering clinically relevant questions. Recently, the lay press(More)
