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.

Human hair has many advantages as a non-invasive sample; however, analytical methods for detecting perfluoroalkyl substances (PFASs) in human hair are still in the development stage. Therefore, the ai...
Microwave-assisted extraction is compared with a more classical technique, Soxhlet extraction, to determine the content of triterpene acids in olive skins. The samples used in their original unmilled ...
Human scalp hair samples were collected and used to assess exposure to toxic elements and essential elements in the state of North Carolina, USA using accelerated microwave assisted acid digestion and...
Population growth combined with increasingly limited resources of arable land and fresh water has resulted in a need for alternative protein sources. Macroalgae (seaweed) and microalgae are examples o...
The impact of microwave irradiation on the in-solution digestion processes and the detection limit of proteins are systematically studied. Kinetic processes of many peptides produced through the tryps...

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.
