  • Allergic inflammation requires the orchestration of altered gene expression in the target tissue and in the infiltrating immune cells. The transcription factor STAT6 is critical in activating cytokine gene expression and cytokine signaling both in the immune cells and in target tissue cells including airway epithelia, keratinocytes and esophageal epithelial cells. STAT6 is activated by the cytokines IL-4 and IL-13 to mediate the pathogenesis of allergic disorders such as asthma, atopic dermatitis, food allergy and eosinophilic esophagitis (EoE). In this review, we summarize the role of STAT6 in allergic diseases, its interaction with the co-factor PARP14 and the molecular mechanisms by which STAT6 and PARP14 regulate gene transcription.

  • The preservation of a healthy periodontal attachment is the most significant factor in the long-term prognosis of a restored tooth. The 'Biologic Width' is composed of the connective tissue attachment and the epithelial attachment in the dentogingival junction. The violation of the biologic width may result in a progressive inflammatory process and crestal bone loss. So a careful soft tissue management is needed to preserve it for the gingival health and an esthetic restoration. The following clinical cases show the five different situations of the violation of the biologic width and their management.

  • Berger formulation was used to calculate the dose distribution of $^{60}$ Co source in tissue. $^{60}$ Co source was supposed as point source. The effect of the stainless-steel around the source was considered and Taylor Approximation Method was used for calculating exposure build-up factor. Calculated depth dose data was compared with measured data which was measured by the ionization chamber.

  • The generalized Bathe method, proposed by Webb and Fox, which is a method of calculation of dose correction factor for the purpose of heterogeneous tissue, is complex even for a few kind of tissues. The method was modified for the purpose of getting a simple method that divide the multilayer of heterogeneous tissues into some groups of adjacent-tissue pairs. This new method could reduce the number of exponential terms and the time for calculating the dose correction factors by manual and computer calculation.

  • Epicardial adipose tissue(EAT) is metabolically active endocrine organ that secretes several hormones in fat thickness is a risk factor for cardiovascular disease and metabolic disorders. This study was to measure and then using ultrasound epicardial adipose tissue thickness, abdominal subcutaneous fat thickness in the target group correlates and general blood properties and characteristics, and presents a local thickness for prediction of metabolic disorders. Results epicardal adipose tissue of the average thickness measured in each of the subjects was 8.890mm, 4.783mm, 4.777, 6.147mm in each section. Showed the epicardial adipose tissue in correlation with the average thickness of the risk factors age, BMI, SBP, LDH, LDL, TC is a positive correlation relationship(p<0.05) in each section. In particular, the thickness of the metabolic disorders epicardial adipose tissue thickness, abdominal subcutaneous compared to subjects that do not have the risk subjects with a risk factor for fat significantly higher(p<0.05). It showed the most reliable that can be cut-off value of 8.950mm obtained with 66.7 % sensitivity and 80 % specificity for predicting the risk of metabolic disorders.

  • Stiffness of the posterior deltoid is as a causative factor in the limited range of glenohumeral horizontal adduction and various other shoulder pathologies including shoulder impingement syndrome, frozen shoulder, and humerus anterior glide syndrome. The purpose of this study was to compare the effects of two techniques (soft tissue massage and cross-body stretch) on increasing the range of horizontal adduction. Thirty-two subjects with a $10^{\circ}$ or greater difference between the right and left sides in horizontal adduction were selected. Sixteen subjects from each group were allocated randomly. Interventions were applied on six occasions for 2 weeks, and the range of horizontal adduction was measured using an inclinometer at pre-and post-intervention. A $2{\times}2$ analysis of variance (intervention${\times}$time) was used to compare the effects of the two techniques. In the soft tissue massage group, the angle of horizontal adduction significantly increased compared with the cross-body stretch group. These findings indicate that the soft tissue massage of the posterior deltoid muscle is a more effective method to increase the flexibility of the glenohumeral horizontal adduction.

  • Periodontitis is characterized by gingival inflammation and results in periodontal pocket formation with loss of the supporting alveolar bone and connective tissue around the teeth. Therapeutic modalities should therefore aim not only at eliminating the gingival inflammatory process and preventing the progression of periodontal disease but also at reestablishing and regenerating the periodontal tissue previously lost to the disease. To achieve periodontal regeneration, progenitor cells must migrate to the denuded root surface, attach to it, proliferate and mature into an organized and functional fibrous attachment apparatus. Likewise, progenitor bone cells must also migrate, proliferate, and mature in conjunction with the regenerating periodontal ligament. Significant advances have been made during the last decade in understanding the factors controlling the migration, attachment and proliferation of cells. A group of naturally occuring molecules known as polypeptide growth factors in conjunction with certain matrix proteins are key regulators of these biological events. Of these, the fibroblast growth factor(FGF), platelet-derived growth factor(PDGF) , insulin like growth factor(CIGFs), transforming growth factor(TGFs), epidermal growth factor(EGF) and bone morphogenetic growth factor(BMPs) apper to have an important role in periodontal wound healing. The purpose of this study was to determine the effects of BMP on periodontal ligament cells. Human periodontal ligament cells were cultured from extracted tooth for non-periodontal reason. Cultured periodontal ligament cells were treated with BMP. Cellular activities were determined by MTT(3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) assay and ALP(alkaline phosphatase) activity. The results were as follows ; Regardless of cultured time, cellular activities were stimulated by BMP. Also, BMP greatly increased alkaline phosphatase(ALP) in periodontal ligament cells. These results suggest that BMP not only have no cytotoxic effect on periodontal ligament cells, but also have osteogenic stimulatory effect on periodontal ligament cells.

  • Dermal fibroblasts produce the many components of the extracellular matrix (ECM) that are needed to maintain connective tissue integrity and repair tissue injuries. This study investigated the effects of Areca catechu extract (ACE) on dermal fibroblast cell activation. Cultured human dermal fibroblasts were treated with ACE, and then ECM production was determined by ELISA, Western blot and RT-PCR. ACE significantly accelerated the production of type 1 collagen, fibronectin, and transforming growth factor (TGF)-${\beta}1$ by ELISA and type 1 collagen by Western blot assay. ACE also increased the gene expression of COL1A1, TGF-${\beta}1$, keratinocyte growth factor (KGF) and insulin growth factor (IGF)-1. These results suggest that ACE has the potential to stimulate ECM production and that it might be suitable for maintaining skin texture.
