De novo formation of chloroethyne in soil.
To date, chloroethyne in the environment has been proposed to occur as a reactive intermediate during the reductive dechlorination of tri- and tetrachloroethene with zerovalent metals. Such artificial conditions might possibly be found at organohalide-contaminated sites that are surrounded by remediation barriers made of metallic iron. In this paper, it is shown that the highly reactive chloroe...
متن کاملDsbB catalyzes disulfide bond formation de novo.
DsbA and DsbB are responsible for disulfide bond formation. DsbA is the direct donor of disulfides, and DsbB oxidizes DsbA. DsbB has the unique ability to generate disulfides by quinone reduction. It is thought that DsbB oxidizes DsbA via thiol disulfide exchange. In this mechanism, a disulfide is formed across the N-terminal pair of cysteines (Cys-41/Cys-44) in DsbB by quinone reduction. This ...
متن کاملDe-Novo Presentation of Histoid Leprosy on an Unusual Site
Histoid Leprosy (HL) is a rare variant of Lepromatous Leprosy, occurring in long-standing cases, mostly in a background of acquired drug resistance. Patients usually present with sudden onset multiple nodules and plaques, most often involving the skin and subcutaneous tissue of trunk and lower limbs. Here we report an unusual case of de novo (without any history of prior anti-leprotic therapy) ...
متن کاملNitric oxide enhances de novo formation of endothelial gap junctions.
OBJECTIVE Gap junctions (formed by connexins, Cx) are important for functional coordination of cells in the vascular wall. However, little is known about their physiological regulation in this tissue. We examined the effects of nitric oxide (NO), an important mediator of vasomotion, wound healing and angiogenesis, on the formation of gap junctions in endothelial cells (human umbilical vein endo...
متن کاملDe novo bone formation after the sinus lift procedure.
BACKGROUND The primary objective of this study is to use histomorphometric techniques to evaluate the concept that the new bone formed in the maxillary sinus lift procedure emanates from the endosteum of the sinus floor. In addition, the effect of the residual crest vertical dimension on the graft outcome and assessment of osteoclast numbers as an indirect measure of a connection between the cr...
