Introduction: In the scenario of airway obstructions, orthognathic surgery consists of the surgical procedure that aims to correct deformities of the bones of the maxilla and mandible and represents today reality in the world. The growth and function of the nasal, nasopharyngeal and oropharyngeal cavities are associated with normal skull growth. Objective: To make a review of the literature on the Orthognathic Surgery and the efeitos nas vias aéreas superiores em pacientes Classe II. Methods: A total of 58 articles were found involving mesh terms about Orthognathic Surgery. Initially, it was held the exclusion existing title and duplications following the interest described this work. After this process, the summaries were evaluated, and a new exclusion was held. 33 articles were included and discussed in this study. Results and conclusion: The results of the present study provided promising and effective results of the main effects of orthognathic surgery in the upper airways in Class II patients. However, complications may occur. Attention is drawn to the fragility points, to encourage compulsory and detailed recording of the occurrence of complications, as well as the elaboration of a protocol to monitor its evolution. *Correspondence to: Idiberto José Zotarelli Filho, MSc, PhD, Unipos Post graduate and continuing education, Street Ipiranga, 3460, São José do Rio Preto SP, Brazil 15020-040, Tel: +55(17) 98166-6537; E-mail: m.zotarelli@gmail.com

Over the past 10 years, there have been increasingly frequent reports of colonization of niches in the oral cavity by non-Candida albicans Candida (NCAC) species. Among these species, Candida parapsilosis sensu stricto plays a major part both locally and systemically. Evidence shows that it may be the second most frequent yeast isolate, after Candida albicans, as commensal in the oral cavity and as pathogen in blood cultures of patients diagnosed with fungemia. Recent reports suggest that both its distribution and its virulence may be affected by environmental conditions and may increase in situations of oral dysbiosis. Based on this background, we hypothesize that oral mucosa in pathological condition may be a source of candidemia by Candida parapsilosis sensu stricto, when promoted by the conditions in the host. We reviewed the scientific databases in search of evidence which may support such hypothesis. *Correspondence to: Rodríguez ML, University of Buenos Aires, School of Medicine, Institute of Research in Microbiology, Parasitology and Inmunology (IMPaM), Mycology Center.

在过去的10年里，越来越多的报道称，非白色念珠菌(NCAC)物种在口腔壁龛中定植。其中，严格感假丝酵母(parapsilosis sensu stricto)在局部和系统上都起着重要作用。有证据表明，它可能是继白色念珠菌之后第二常见的酵母菌分离物，在诊断为真菌血症的患者的口腔中作为共生体和作为血液培养物中的病原体。最近的报告表明，它的分布和毒力都可能受到环境条件的影响，并可能在口腔生态失调的情况下增加。基于这一背景，我们假设病理状态下的口腔黏膜在宿主的条件促进下可能是念珠菌的来源。我们查阅了科学数据库，寻找可能支持这一假设的证据。*通讯:Rodríguez ML，布宜诺斯艾利斯大学医学院，微生物学、寄生虫学和免疫学研究所(IMPaM)，真菌学中心。布Aires-Argentina;昆卡大学牙科学院，符号学和诊断诊所系。厄瓜多尔，电子邮件:malourdes84@hotmail.com

Bone homeostasis is maintained by osteoclasts and osteoblasts. Regulation of bone homeostasis is important for orthodontic treatments, oral implant, treatment for periodontal disease, osteonecrosis of the jaw and so on. We reported an intermediate filament linking protein Plectin plays important role in osteoclastic bone resorption. Plectin is a large molecule >500 kDa and have 13 isoforms. Individual Plectin isoforms have different roles. To reveal the roles of Plectin in osteoclasts, we examined the expression levels of Plectin isoforms and found the isoforms regulating actin organization are highly expressed in osteoclasts. *Correspondence to: Takuma Matsubara, Division of Molecular Signaling and Biochemistry, Department of Health Improvement, Kyushu Dental University, 2-6-1, Manazuru, Kitakyushu, Fukuoka, 8038580, Japan, Tel: +81-93-285-3049, Fax: +81-93-582-6000, E-mail: r15matsubara@fa.kyu-dent.ac.jp Received: February 01, 2019; Accepted: February 15, 2019; Published: February 18, 2019 Introduction Osteoclasts are one of the major player for bone resorption and regulate bone remodeling to maintain bone homeostasis [1,2]. Activation of osteoclastic bone resorption in comparison with bone formation by osteoblasts results in bone metabolic diseases such as osteoporosis and periodontal disease [3-5]. Moreover, the function of osteoclasts is important in orthodontic treatments, oral implant treatment and pathogenesis of osteonecrosis of the jaw [6-9]. Thus, regulation of osteoclasts is one of the serious themes for improvement of various dental treatments. Osteoclasts are differentiated from hematopoietic stem cells with macrophage colony stimulating factor (M-CSF) and Receptor activator NF-κB ligand (RANKL) stimulation [1,2]. Attachment and sealing of bone matrix by differentiated osteoclasts is essential for bone resorption [10,11]. Actin, tubulin and intermediate filaments are dynamically organized and forms actin ring that is consistent with actin dots called podosomes in cell periphery for attachment and sealing [12-15]. It is well known that the mice defect actin ring formation by knocking out a tyrosine kinase Src are osteopetrosis because of decrease of bone resorbing activity [16,17]. This indicates Src is one of the key molecules to regulate bone resorption. We identified a cytolinker protein Plectin as a partner of Src and organize actin ring formation in osteoclasts [13]. Plectin was highly expressed in brain, heart, skeletal muscle and TRAP(+) MNCs [13,14,18,19]. Plectin has 13 isoforms and there role is a little different each other [18]. This suggests Plectin variants plays different roles in each tissue. Here, we explore the important isoforms of Plectin in osteoclasts. Materials and methods Animals 4 weeks old C57BL6/N mice were purchased from Japan SLC, Inc. (Shizuoka, Japan). Spleen and femoral muscle were obtained from these mice. Spleen cells were differentiated to osteoclast like cells with M-CSF and sRANKL described as pre

为了探索破骨细胞中表达的同种异构体，我们与骨骼肌进行了实时定量PCR分析，其中同种异构体起作用[20](图1)。TRAP(+)跨国公司中Plectin 1、1b、1d、1e、1f和1g的表达水平高于骨骼肌(图1)。由于引物设计，Plectin 1h、1i和1j没有相互区分。另一方面，在TRAP(+)跨国公司中，Plectin 1a和1c较少。
