The effectiveness of microwave-assisted extraction of proteins from human hair samples was evaluated. Extractions were performed from 2-mg hair samples in an extraction solution consisting of 25mM Tris-HCl (pH8.5), 2.6M thiourea, 5M urea, and 5% mercaptoethanol. During extraction, samples were exposed to microwave radiation (600W) for a specified incubation period (5-120min). The extraction efficiency of samples that had been incubated for 60min was similar to that of samples that had been heated at 50 degrees C for 24h using the conventional Shindai method.

Use of various chemical separation and extraction methods, such as SOLID PHASE EXTRACTION; CHROMATOGRAPHY; and SUPERCRITICAL FLUID EXTRACTION; to prepare samples for analytical measurement of components.
The selective extraction of deciduous teeth during the stage of mixed dentition in accordance with the shedding and eruption of the teeth. It is done over an extended period to allow autonomous adjustment to relieve crowding of the dental arches during the eruption of the lateral incisors, canines, and premolars, eventually involving the extraction of the first premolar teeth.
