Needle-shaped rutile inclusions occur in garnet within the quartz-eclogite at Mt. Gongen Sanbagawa belt, central Shikoku. They are approximately 5–25 µm along long axis and typically oriented three directions, each intersecting 120°. This indicates that needle-shaped is a lamella exsolved from garnet. Garnet with needle-rutile restricted to quartz-poor domain of quartz eclogite sample, which co...

BACKGROUND Premedication with sedatives can decrease the discomfort associated with invasive anesthetic procedures. Some researchers have shown that acupressure on the acupuncture extra 1 point is effective for sedation. We investigated whether acupressure on the extra 1 point could alleviate the pain of needle insertion. METHODS We investigated the effect of acupressure at the extra 1 point ...
