Article Abstract

We have cloned and characterized the gene encoding the late histone H1-beta subtype from the sea urchin Strongylocentrotus purpuratus. The gene contains all of the upstream sequence homologies previously seen in late H1-gamma genes. The expression of H1-beta mRNA is coordinated with that of H1-gamma mRNA, and like H1-gamma it is expressed in all adult somatic tissues tested.

To address the challenge of antibiotic-containing wastewater, a novel micromagnetic carrier-modified integrated fixed-film activated sludge system (MC-IFAS) was developed for treating tetracycline (TC)-containing swine wastewater in this study. The magnetic effects of the MC significantly enhanced TC removal by improving TC biosorption and biodegradation in both the suspended activated sludge and the carrier-attached biofilm in the MC-IFAS. The increased electrostatic attraction and number of binding sites in both the activated sludge and the biofilm enhanced their TC biosorption capacities, particularly in the activated sludge.

Background: Machupo virus (MACV) is a New World mammarenavirus (hereafter referred to as "arenavirus") and the etiologic agent of Bolivian hemorrhagic fever (BHF). No vaccine or antiviral therapy exists for BHF, which causes up to 35% mortality in humans. New World arenaviruses evolve separately in different locations.
