Abstract

We previously reported using a microguidewire with a curved, pigtail-shaped tip as an anchor for navigating a microcatheter. However, we considered that the microcatheter could follow even if the tip of wire did not advance so far distally. The present study assessed the usefulness of a modified version of this pigtail-shaped microguidewire for navigating microcatheters to difficult vasculatures during neurointerventions. The microguidewire was repeatedly evaluated using a silicon tube vascular model. We also employed this method as the first choice for some patients. In both the in vitro tests and clinical use, the round curved tip could be used to position the microguidewire at the entry of a sharply angled vessel or aneurysmal neck, and the following catheter could then be advanced gently and easily. This technique allowed navigation of the microcatheter without inserting the guidewire into the distal vasculature.

Climate Change
Abstract

Scientific evidence suggests that cumulative GHG emissions have already caused climate change, which tolled victims all over the world but quite often charged disproportionally high costs to poor segment of the world, and substantial mitigation actions are needed to avoid irreversible catastrophic change in ecosystems that underpin very human survival. As a group of world leading countries, G20 is expected not only to pioneer ambitious actions for transition to low-carbon or decarbonized society but also to lead international cooperation in capacity development of less developed countries for implementing ambitious actions and in financing such actions.

89. Key elements related to the emissions trading for the Kyoto protocol

Abstract

The Protocol on emissions trading by the US government can serve as a policy framework for the management of global climate change issues, which are to be taken up at the United Nations conference in Kyoto, Japan in December 1997. The Protocol was original in its proposal for an emissions trading scheme between governments. However, some problems remain to be solved, such as the setting up of an intergovernmental agency to monitor market functions, capital transfer difficulties in developing countries, and mismatches in emissions trading between Organization of Economic Cooperation and Development members.

Abstract

This report describes a cost‐effective experimental method for determining an intrinsically disordered protein (IDP) region in a given protein sample. In this area, the most popular (and conventional) means is using the amide ((1)H(N)) NMR signal chemical shift distributed in the range of 7.5–8.5 ppm. For this study, we applied an additional step: analysis of (1)H(N) chemical shift temperature coefficients ((1)H(N)‐CSTCs) of the signals. We measured (1)H–(15)N two‐dimensional NMR spectra of model IDP samples and ordered samples at four temperatures (288, 293, 298, and 303 K). We derived the (1)H(N)‐CSTC threshold deviation, which gives the best correlation of ordered and disordered regions among the proteins examined (below −3.6 ppb/K). By combining these criteria with the newly optimized chemical shift range (7.8–8.5 ppm), the ratios of both true positive and true negative were improved by approximately 19% (62–81%) compared with the conventional “chemical shift‐only” method.

94. A proposal for the Protocol(s) on climate change

Abstract

Formulating the Protocols for the control of greenhouse gases that effect climate changes can be made more effective by allowing the Protocol some flexibility in its list of greenhouse gases to control, implementing the protocols with a small number of assenting nations, and breaking down implementation to specific time frames. These measures will ensure that progressive reviews and revisions can be made on the Protocols to ensure its implementation.
