BACKGROUND: The forward surgical team (FST) is the US Army's smallest surgical element. These teams have supported current conflicts since 2001. The purpose of this study was to determine if surgeon utilization varied at two different FSTs and to determine factors that may predict the need for a surgeon. METHOD: Data from two FSTs were reviewed. A t-test was used to compare the military injury severity scores (mISS) and the revised trauma scores (RTS). χ(2) analysis was used to compare types and mechanisms of injury and to compare life- or limb-saving surgeries (LLSS) and life-saving interventions among the FSTs...

Nitric oxide (NO) is an atypical neurotransmitter that has been related to the pathophysiology of major depression disorder. Increased plasma NO levels have been reported in depressed and suicidal patients. Inhibition of neuronial nitric oxide synthase (nNOS), on the other hand, induces antidepressant effects in clinical and pre-clinical trials. The mechanisms responsible for the antidepressant-like effects of nNOS inhibitors, however, are not completely understood. In this study, genomic and proteomic analyses were used to investigate the effects of the preferential nNOS inhibitor 7-nitroindazole (7-NI) on changes in global gene and protein expression in the hippocampus of rats submitted to forced swimming test (FST)...

RATIONALE: Systemic inhibition of neuronal nitric oxide synthase (nNOS) induces antidepressant-like effects in rodents. The mechanisms and brain regions mediating this effect are still unknown. The hippocampus is a brain region proposed to mediate adaptation to stress and antidepressant behavioral effects. Therefore, it could be involved in the antidepressant effects of NOS inhibitors. OBJECTIVES: To test the hypothesis that nNOS inhibition in the dorsal hippocampus will induce antidepressant-like effects in the forced swimming test (FST) in rats...

The genetic composition of Poa annua L. populations with a series of traffic pollution was studied by starch electrophoresis. Five enzyme systems were stained. The results showed that: (1) Traffic pollution can dramatically change genotypic frequencies at some loci of P. annua populations. Significant deviations from Hardy-Weinberg equilibrium were observed on loci Fe-1 and Me due to the excess of heterozygotes in some populations. (2) The effective number of alleles per locus and the observed and expected heterozygosity were higher in the pollution series than in the clear control site (Botanic Park population), but the increase was not related with the pollution extent...

Thirty years and 23 yr of life history data from a Hereford herd in Arizona and an Angus herd in Wyoming, respectively, were analyzed. Longevity averaged 4.21 +/- .06 for years from first calving to disposal (FST), 7.40 +/- .06 for years from birth to disposal (AGE) and 3.46 +/- .06 for lifetime number of calves weaned (NUM) in Herefords and 4.49 +/- .13 (FST), 6.68 +/- .12 (AGE) and 3.66 +/- .11 (NUM) in Angus. In the Hereford herd, heritability estimates for traits measuring longevity, estimated from daughter-dam regression and paternal half-sib analyses, ranged from ...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
