Characterization of the volatile fraction of mastic oil and mastic gum

Natural Product Research, 2020
GC-MS of ethyl acetate solutions and HS-SPME-GC-MS of mastic oil and mastic gum showed the presence of α-pinene and β-myrcene as main components of the mixture. In the GC-MS analysis of mastic oil 19 compounds were detected, while mastic gum allowed to detect only twelve compounds.

Masticator myopathy

Muscle & Nerve, 2003
AbstractA 31‐year‐old woman developed low‐grade fever and pain and swelling of the masticatory muscles. A T2‐weighted magnetic resonance image showed high signal intensity in these muscles. Coxsackie B3 and echo 30 viruses were detected from a nasopharyngeal swab and feces, respectively.

The effect of mastication time on the physical properties and structure of natural rubber

, 2020
The effect of mastication time in an internal mixer on the physical properties and microstructure of natural rubber (NR) was studied. The Mooney viscosity, plasticity, and complex viscosity reduced with increases in the mastication time due to the ...

Hemangiopericytoma of the Masticator Space

Annals of Otology, Rhinology & Laryngology, 1996
Hemangiopericytomas are rare tumors of the head and neck. The benign presentation of this tumor belies its high local recurrence rate, local aggressiveness, and malignant potential. In view of these characteristics, workup to provide a diagnosis preoperatively is of significant importance. Diagnostic imaging is helpful in planning operative management,

Oral physiology and mastication

Physiology & Behavior, 2006
Mastication is a sensory-motor activity aimed at the preparation of food for swallowing. It is a complex process involving activities of the facial, the elevator and suprahyoidal muscles, and the tongue. These activities result in patterns of rhythmic mandibular movements, food manipulation and the crushing of food between the teeth. Saliva facilitates

Mastication of Rubber. I. Mechanism of Plasticizing by Cold Mastication

Rubber Chemistry and Technology, 1952
Abstract The process of cold mastication has been rationalized in terms of recognized chemical reactions, and its essential difference from the hot mastication process has been demonstrated. Many apparently unrelated phenomena occurring on cold mastication, as, for example, are collected in a recent survey, can be interpreted as specific ...

Research into mastication*

Australian Dental Journal, 1976
Abstract— An electronic method of recording displacement was used to study mandibular movement during mastication. The technique enables the parameters of muscle activity, the sound of tooth contact, the force developed between opposing teeth, and the displacement of the mandible to be recorded at the same time on a single U/V chart.
