The present invention relates to peptides which exhibit potent anti-retroviral activity. Respective width direction outside surfaces of the two outer column half bodies are sandwiched between the two hanging side portions of the pivot bracket, and the two fixing side portions of the fixing bracket are connected such that the two width direction outside surfaces of the two outer column half bodies can be clamped and released by the clamping tool. In an anytime embodiment the GPS receiver enters an operation mode at any time in order to minimize user request latency. When the support portion is within the opening, an upper surface of the opening contacts the upper support surface of the support portion, and the extension is engagingly received within a portion of the opening.
