“…Orthopedics of the head and neck were the subject of two articles: in a murine model, Mariúba et al 17 investigated in male Wistar rats the effects of thyroid hormones(known to regulate the expression of genes that control bone mass and the oxidative properties of muscles) on the stomatognathic system issue by evaluating: (i) osteoprotegerin (OPG) and osteopontine (OPN) mRNA expression in the maxilla,(ii) myoglobin mRNA and protein expression, (iii) fiber composition of the masseter. Thyroidectomy increased osteoprotegerin and osteopontine mRNA expression, while T3 treatment reduced osteoprotegerin (~40%) and osteopontine.…”

This paper is a review of articles published in Brazilian scientific periodicals in recent years. Its main purpose is to bring to the attention of the readership of Acta Ortopedica Brasileira original contributions to the field published in non-specialized journals. We hope that this will serve as a general scientific update for readers. The review includes works published in six ISI indexed non-orthopedic journals, following a literature search conducted in fourteen such journals.

Developmental, Physiological and Phylogenetic Perspectives on the Expression and Regulation of Myosin Heavy Chains in Craniofacial Muscles

This review deals with the developmental origins of extraocular, jaw and laryngeal muscles, the expression, regulation and functional significance of sarcomeric myosin heavy chains (MyHCs) that they express and changes in MyHC expression during phylogeny. Myogenic progenitors from the mesoderm in the prechordal plate and branchial arches specify craniofacial muscle allotypes with different repertoires for MyHC expression. To cope with very complex eye movements, extraocular muscles (EOMs) express 11 MyHCs, ranging from the superfast extraocular MyHC to the slowest, non-muscle MyHC IIB (nmMyH IIB). They have distinct global and orbital layers, singly- and multiply-innervated fibres, longitudinal MyHC variations, and palisade endings that mediate axon reflexes. Jaw-closing muscles express the high-force masticatory MyHC and cardiac or limb MyHCs depending on the appropriateness for the acquisition and mastication of food. Laryngeal muscles express extraocular and limb muscle MyHCs but shift toward expressing slower MyHCs in large animals. During postnatal development, MyHC expression of craniofacial muscles is subject to neural and hormonal modulation. The primary and secondary myotubes of developing EOMs are postulated to induce, via different retrogradely transported neurotrophins, the rich diversity of neural impulse patterns that regulate the specific MyHCs that they express. Thyroid hormone shifts MyHC 2A toward 2B in jaw muscles, laryngeal muscles and possibly extraocular muscles. This review highlights the fact that the pattern of myosin expression in mammalian craniofacial muscles is principally influenced by the complex interplay of cell lineages, neural impulse patterns, thyroid and other hormones, functional demands and body mass. In these respects, craniofacial muscles are similar to limb muscles, but they differ radically in the types of cell lineage and the nature of their functional demands.
