Stimulation of a neural pathway originating in the brainstem reticular formation, with synapses in the medial hypothalamus, activates the hippocampal theta rhythm. The frequency of reticular-elicited theta is determined in the medial supramammillary nucleus (mSuM) completely in anaesthetised rats, but only partially when the animal is awake. We tested other(More)
AIM True left ventricular aneurysms are rarely encountered in childhood. Etiological factors are varied and often indeterminable. There is a paucity of literature detailing the surgical techniques used to repair pediatric aneurysms. METHODS Three children aged 21 months, 19 months and 5 years with true left ventricular aneurysms underwent surgical repair(More)
This study reports an experimental, randomized controlled clinical trial comparing three treatments for smoking cessation: sustained-release bupropion, nicotine patch, and combination nicotine and bupropion, to a counseling-only control group (N = 140), for smoking sailors aboard seven Navy ships. The purpose was to determine the effectiveness of different(More)
The United States military has the legacy of a pro-tobacco culture and still has prevalence rates of tobacco use that are higher than their civilian counterparts. One tactic for decreasing use and the subsequent health problems is through effective tobacco control policies. We collected available tobacco control policies from all four branches of the(More)
The effect of occlusion on the in vitro percutaneous absorption of linoleic acid was investigated. A greater skin concentration of linoleic acid from an ethanolic vehicle was observed in non-occluded experiments compared with occluded experiments (P<0.05). Such changes were not observed as consistently when ethanol was replaced with a less volatile organic(More)
Although elective abdominal aortic aneurysm (AAA) repair can be done with a less than 5% mortality rate, ruptured AAAs have a 32-85% mortality rate. The aims of this study were: (i) to identify prognostic factors affecting mortality; (ii) to identify and assess the impact of postoperative complications on mortality; and (iii) to try to identify a subgroup(More)
