Therefore, the unilateral hypofunction of the masseter leads to molecular and morphological signs of atrophy in both the BoNTA-injected muscle and its agonistic non-injected masticatory muscles. The generalized effect on the mouse masticatory apparatus when one of its components is intervened suggests ...
the oral cavity[16]. Three major cell types are found in these glands such as acinar, ductal andmyoepithelial cells. The saliva producing triangular shapedacinar cellsare arranged in the form of bunches calledaciniwhich form a lumen into which theyrelease salivawith the help of myoepithelial ...
Therefore, to clarify the functional role of each masticatory muscle, the myofiber properties of the adult mouse masticatory muscles were investigated at the transcriptional level. Expression of MyHC-2b with a fast contraction rate and strong force was frequently noted in the temporal and masseter ...
Only 1 patient received invasive procedures in the form of local trigger point injection to the masseter muscle for myofascial pain syndrome. Only 2 patients received targeted physical therapy for myofascial pain syndrome. This was in contrast to 6 patients in whom a significant component of their ...
As the basis of an examination of the mechanics of the muscles, the following are described:temporal, masseter, internal and external pterygoids, digastric, mylohyoid, geniohyoid and transverse mandibular.W.

However, the rate of force generation and relaxation was slower in female masseter muscles. Assessment of fibre type distribution by immunohistochemistry revealed a three-fold decrease in the proportion of myosin heavy chain 2b positive fibres in female masseters, which correlated with the differences ...
Promoting brown adipose tissue (BAT) activity innovatively targets obesity and metabolic disease. While thermogenic activation of BAT is well understood, the rheostatic regulation of BAT to avoid excessive energy dissipation remains ill-defined. Here, we demonstrate that adenylyl cyclase 3 (AC3) is ke...
Methods Fifteen edentulous elderly who wore only the upper CD were selected and received new upper and lower CD. Volunteers were evaluated at baseline and after 1, 3 and 6 months of new prosthesis use. Masticatory performance (MP) was assessed by the sieving method (X50 values). Masseter ...
An incision through the full thickness of the skin was made along the inferior border of the unilateral mandible and the masseter muscle and periosteum were removed to expose the buccal surface of the mandible. An inverted cone bur, supported with copious saline irrigation, was used to remove ...
The reference electrode was inserted into the masseter muscle. The EMG activity of the mylohyoid muscle was evoked and acquired with the Spike2 software (CED, Cambridge, UK) when mice were given water (2 μl/s, 10 s) by a micro-injection pump (HARVARD, USA) after waking up from ...
