Under the Japanese biosafety regulatory framework for transgenic plants, data for assessing a transgenic plant’s impact on biodiversity must be submitted in order to obtain approval for a confined field trial. We recently reported the development of four novel transgenic Eucalyptus camaldulensis clones expressing the bacterial choline oxidase A (codA) gene, i.e., codAH-1, codAH-2, codAN-1, and codAN-2, and evaluated their abiotic tolerance by semiconfined screen house trial cultivation. Here we evaluated the impacts of the transgenic E. camaldulensis clones on productivities of harmful substances from those clones to affect soil microorganisms and/or other plants in the environment. A comparison of the assessment data between the transgenic trees and non-transgenic comparators showed no significant difference in potential impacts on biodiversity. The results contribute to sound-science evidence ensuring substantial equivalence between transgenic and non-transgenic E. camaldulensis.

Six patients with ear diseases caused by nose blowing are described. Four of them developed perilymphatic fistula.Exploratory tympanotomy was performed on the left ear of case 1 who complained of tinnitus. Leakage was identified in the area of the round window, which was covered with a piece of perichondrium. Three patients (cases 2-4) complained of tinnitus and a floating sensation, echo sound, and dizziness. All of them have the habit of nose blowing.The symptoms disappeared spontaneously after a rest.Two patients (cases 5 and 6) developed fullness of the ear after nose blowing. They were diagnosed as suffering from bullous myringitis. Nose blowing may predispose to formation of bubbles within an infected tympanic membrane.

We measured the high-resolution magnetic images using an STM-SQUID microscope that combines a high-Tc superconducting quantum interference device (SQUID) with a scanning tunneling microscope (STM). In the STM-SQUID microscope, the STM probe plays the important role of a flux guide and is responsible for tunneling current detection. Therefore, it is essential to investigate the probe itself in order to improve the magnetic image resolution. We optimized the electrochemical polishing condition to realize the fine probe with a tip radius of 50 nm or less. We fabricated the various shaped probes by controlling the voltage during sharpening. The tip radius of 50 nm or less was achieved when the probe tip was sharpened at the applied voltage of 30 V. We then measured the magnetic images of typical magnetic materials, such as a steel sample and nickel thin films, using the probe with a tip radius of 50 nm or less. The magnetic domain structures were observed clearly.
