Unknown Tongues: Black Women\u27s Political Activism in the Antebellum Era, 1830-1860

Vindicated voices Study recovers history of struggle According to the American humorist Oliver Herford, a man is known by the silence he keeps. Perhaps this is so, but women\u27s silences, we must acknowledge, have long rendered them unknown. So much more has this been the case with...

Injury severity and serum amyloid A correlate with plasma oxidation-reduction potential in multi-trauma patients: a retrospective analysis

<p>Abstract</p> <p>Background</p> <p>In critical injury, the occurrence of increased oxidative stress or a reduced antioxidant status has been observed. The purpose of this study was to correlate the degree of oxidative stress, by measuring the oxidation-reduction potential (ORP) of plasma in the critically injured, with injury severity and serum amyloid A (SAA) levels.</p> <p>Methods</p> <p>A total of 140 subjects were included in this retrospective study comprising 3 groups: healthy volunteers (N = 21), mild to moderate trauma (ISS < 16, N = 41), and severe trauma (ISS ≥ 16, N = 78). For the trauma groups, plasma was collected on an almost daily basis during the course of hospitalization. ORP analysis was performed using a microelectrode, and ORP maxima were recorded for the trauma groups. SAA, a sensitive marker of inflammation in critical injury, was measured by liquid chromatography/mass spectrometry.</p> <p>Results</p> <p>ORP maxima were reached on day 3 (± 0.4 SEM) and day 5 (± 0.5 SEM) for the ISS < 16 and ISS ≥ 16 groups, respectively. ORP maxima were significantly higher in the ISS < 16 (-14.5 mV ± 2.5 SEM) and ISS ≥ 16 groups (-1.1 mV ± 2.3 SEM) compared to controls (-34.2 mV ± 2.6 SEM). Also, ORP maxima were significantly different between the trauma groups. SAA was significantly elevated in the ISS ≥ 16 group on the ORP maxima day compared to controls and the ISS < 16 group.</p> <p>Conclusion</p> <p>The results suggest the presence of an oxidative environment in the plasma of the critically injured as measured by ORP. More importantly, ORP can differentiate the degree of oxidative stress based on the severity of the trauma and degree of inflammation.</p

GIS Historical Atlas Assignment

Curatorial note from Digital Pedagogy in the Humanities: Students delve into historical census data to produce a small atlas that addresses questions about race and slavery in mid-nineteenth-century America. They produce not only maps but also tables and charts, consistent with the census’s emphasis on quantitative data. Students begin with a question that they wish to answer, comparing variables across different geographies, across time, or exploring possible correlations. This models a good practice for census data: to have a specific question that data will help address. Otherwise, census data can readily become overwhelming in its specificity and abundance. The GIS “codebook” facilitates the use of the “real” data, which is necessarily obtuse and confusing in its authenticity. Rael chose to do extensive out-of-class work to prepare supporting instructional materials so that students focus on the analysis while minimizing time spent grappling with data. This assignment could be adapted for census data from any time period
