Conferring High IAA Productivity on Low-IAA-Producing Organisms with PonAAS2, an Aromatic Aldehyde Synthase of a Galling Sawfly, and Identification of Its Inhibitor.

Gall-inducing insects often contain high concentrations of phytohormones, such as auxin and cytokinin, which are suggested to be involved in gall induction, but no conclusive evidence has yet been obtained. There are two possible approaches to investigating the importance of phytohormones in gall induction: demonstrating either that high phytohormone productivity can induce gall-inducing ability in non-gall-inducing insects or that the gall-inducing ability is inhibited when phytohormone productivity in galling insects is suppressed. In this study, we show that the overexpression of , which encodes an aromatic aldehyde synthase (AAS) responsible for the rate-limiting step in indoleacetic acid (IAA) biosynthesis in a galling sawfly ( sp.

Tuberculosis affecting multiple vertebral bodies.

Spinal tuberculosis usually occurs in a single vertebral body or two to three adjacent vertebrae; it rarely occurs in multiple vertebral bodies. Surgery is indicated in cases that do not improve with conservative therapy, or when paralysis is evident. Two cases regarding patients with spinal tuberculosis in multiple vertebral bodies on whom surgery was performed are reported.

Photocatalytic TiO2 particles confer superior antibacterial effects in a nutrition-rich environment: an in vitro study.

Titanium dioxide (TiO(2)) is known to confer photocatalytic bactericidal effects under ultraviolet (UV) irradiation. Few reports are available, however, on the clinical applications of TiO(2) particle mixtures. Our objective in the present research was to evaluate the in vitro bactericidal effects of a TiO(2) particle mixture in a nutrition-rich biological environment.

Clinical relevance of heparin-PF4 complex antibody in DVT after total joint replacement.

Background: Antibodies to the heparin-platelet factor-4 (HPF-4) complex (HIT antibodies) have been observed in patients with heparin-induced thrombocytopenia (HIT). These antibodies are thought to be involved in thrombosis through activation of platelet/endothelial cells. This prospective study was conducted to determine the incidence of post-operative HIT antibodies to assess the associated risk of deep vein thrombosis (DVT) in patients undergoing total knee arthroplasty (TKA) or total hip arthroplasty (THA).
