Abstract

Intestinal inflammation is a painful syndrome with multiple symptoms, including chronic pain. This study examined the possible role of sensory neurons and substance P in symptoms of an animal model of acute intestinal inflammation. The model was induced by injecting ethanol and zymosan into the colon of anesthetized male rats. Three hours later, sections of the colon were stained with hematoxylin and eosin. To determine the role of substance P, 5 mg/kg of the neurokinin-1 receptor (NK-1r) antagonist, CP-96,345, or 300 microg/kg of an antisense oligonucleotide targeted at NK-1r mRNA was administered. Spinal cord sections were examined for internalization of NK-1r, as an indicator of substance P release. Sections of colon revealed infiltration of inflammatory cells following ethanol and zymosan treatment. Plasma extravasation in rats given ethanol and zymosan was significantly greater than in controls given saline only (P

Abstract

This paper deals with an experimental assessment of the performance of different damping systems in controlling wind-induced conductor motions. The damping systems comprised different types of Stockbridge dampers or bretelles used on single ACSR and AAAC conductors as well as spacer-dampers or semi-rigid spacers combined or not with bretelles used on similar triple or quad bundled conductors. All tests were conducted under natural wind conditions at the Hydro-Quebec test line in Varennes, Quebec.

Abstract

After the January 12, 2010, Haiti earthquake, we deployed a mainly offshore temporary network of seismologic stations around the damaged area. The distribution of the recorded aftershocks, together with morphotectonic observations and mainshock analysis, allow us to constrain a complex fault pattern in the area. Almost all of the aftershocks have a N-S compressive mechanism, and not the expected left-lateral strike-slip mechanism. A first-order slip model of the mainshock shows a N264 degrees E north-dipping plane, with a major left-lateral component and a strong reverse component. As the aftershock distribution is sub-parallel and close to the Enriquillo fault, we assume that although the cause of the catastrophe was not a rupture along the Enriquillo fault, this fault had an important role as a mechanical boundary. The azimuth of the focal planes of the aftershocks are parallel to the north-dipping faults of the Transhaitian Belt, which suggests a triggering of failure on these discontinuities. In the western part, the aftershock distribution reflects the triggering of slip on similar faults, and/or, alternatively, of the south-dipping faults, such the Trois-Baies submarine fault. These observations are in agreement with a model of an oblique collision of an indenter of the oceanic crust of the Southern Peninsula and the sedimentary wedge of the Transhaitian Belt: the rupture occurred on a wrench fault at the rheologic boundary on top of the under-thrusting rigid oceanic block, whereas the aftershocks were the result of the relaxation on the hanging wall along pre-existing discontinuities in the frontal part of the Transhaitian Belt.

41. Sociodemographic factors and the variation in syphilis rates among US counties, 1984 through 1993: an ecological analysis

Abstract

0bjectives, Syphilis in the United States is focally distributed. with high incidence rates in the South and in metropolitan areas nationwide. In this study an ecological analysis, using the county as the unit of analysis, was performed to genetate hypotheses about community-level determinants of syphilis rates. Methods. Bivariate rank conelations and multivariate, backward stepwise elimination linear regressions were performed. Mean annual incidence of primary- and secondary-stage syphilis in a county was the dependent variable, and county sociodemographic characteristics (from census data) were the independent variables. Results. In the multivariate regression model, sociedemographic characteristics accounted for 71% of the variation in syphilis rates among countieS. With other factors accounted for, the most highly correlated characteristics were percentage non-Hispanic Black populations, county location in the South, percentage of the population that was urban, percentage Hispanic population, and percentage of births to women younger than 20 years. Conclusions. Most of the variation in syphitis rates among counties is accounted for by sociodemographic characteristics. Identification and remediation of modifiable health determinants for which these factors are markers are. needed to improve the health status of these populations.

43. A LU:-16 individual with antibodies

Author

Abstract

Antibodies against Lutheran blood group antigens have been observed during first-time pregnancy. Samples from a woman of African descent were tested in our immunohematology laboratory on several occasions since 2001. Her samples were phenotyped as Lu(a+b-), and anti-Lubwas suspected but not identified. She was asked to make autologous donations in preparation for her delivery, which she did. In 2010, two antibodies were identified: anti-Leaand -Lub. Six years later, a third investigation was requested. This time, an antibody directed at a high-prevalence Lutheran antigen was found in addition to the anti-Leaand -Lubpreviously observed. Her serum was compatible with three out of five Lu(a-b-) reagent red blood cells (RBCs). One of the incompatible Lu(a-b-) reagent RBCs was known to be In(Lu) (KLF1mutation). The genetic background of the other reagent RBC was unknown. The LUcDNA sequence analysis revealed the presence of the c.230G>A (Lua), c.679C>T (LU:–16), and a silent polymorphism c.1227G>T. Anti-Lu16 was highly suspected. This would be the fifth case of LU:–16 with antibodies reported, all within women of African heritage with the Lu(a+b-) phenotype. Hemolytic disease of the fetus and newborn was not noted in these cases. Immunohematology2017;33:110–113.
