Harambee!: A pilot mixed methods study of integrated residential HIV testing among African-born individuals in the Seattle area.

Background: African-born individuals in the U.S. are disproportionately affected by HIV yet have low HIV testing rates.

Placental telomere length and risk of placental abruption.

Objective: To investigate the associations of placental telomere length with placental abruption (PA) risk and interactions between placental telomere length and placental mitochondrial DNA (mtDNA) copy number on PA risk.

Materials And Methods: Relative telomere length and mtDNA copy number in placental samples collected from 105 cases and 73 controls were measured in two batches using qRT-PCR. Mean differences in relative telomere length between PA cases and controls were examined.

First recorded eruption of Nabro volcano, Eritrea, 2011.

We present a synthesis of diverse observations of the first recorded eruption of Nabro volcano, Eritrea, which began on 12 June 2011. While no monitoring of the volcano was in effect at the time, it has been possible to reconstruct the nature and evolution of the eruption through analysis of regional seismological and infrasound data and satellite remote sensing data, supplemented by petrological analysis of erupted products and brief field surveys. The event is notable for the comparative rarity of recorded historical eruptions in the region and of caldera systems in general, for the prodigious quantity of SO emitted into the atmosphere and the significant human impacts that ensued notwithstanding the low population density of the Afar region.
