  • Purpose: The epidermal growth factor receptor (EGFR) family plays a crucial role in the growth of malignant tumors. EGFR and human EGFR 2 (HER2) protein overexpression are associated with an unfavorable prognosis and are important therapeutic targets in breast cancer. The aim of this study was to evaluate the relationship between EGFR and HER2 expression and clinicopathological factors in papillary thyroid carcinoma (PTC) at a single institution. Methods: A total of 129 consecutive patients with PTC were enrolled in this study and underwent thyroid surgery between October 2013 and February 2015. EGFR and HER2 protein expression was evaluated in the 129 primary tumors by immunohistochemistry, and the results were compared with the clinicopathological features. Results: Of the 129 PTC tumors, 20 (15.5%) were HER2 positive, and 109 (84.5%) were HER2 negative. Moreover, EGFR positivity were observed in 111 (86%) tumors. The mean age of the patients was $46.3{\pm}11.9years$ (range, 20-74 years), and the mean tumor size was $1.08{\pm}0.75cm$ (range, 0.2-3.5 cm). Tumor size, extrathyroidal extension, histological subtype, and TNM stage were not significantly associated with EGFR or HER2 expression. Meanwhile, high Ki-67 labeling index was significantly associated with EGFR expression (P=0.002), HER2 expression was significantly associated with younger age (${\leq}45years$) and cervical lymph node metastasis. Conclusion: Based on our data, it is not clear whether EGFR and HER2 expression is associated with tumor aggressiveness in PTC.

  • Gastric cancer is heterogeneous in morphology, biology, genomics, and treatment response. Alterations in human epidermal growth factor receptor 2 (HER2) overexpression, microsatellite instability (MSI) status, programmed death-ligand 1 (PD-L1) levels, and fibroblast growth factor receptor 2 (FGFR2) can be used as biomarkers. Since the combination of fluoropyrimidine/platinum plus trastuzumab that was investigated in the ToGA trial was approved as a standard of care in HER2-positive patients in 2010, no other agents showed efficacy in the first- (HELOISE, LOGiC, JACOB trials) and second- (TyTAN, GATSBY, T-ACT trials) line treatments. Despite the success in treating breast cancer, various anti-HER2 agents, including a monoclonal antibody (pertuzumab), an antibody-drug conjugate (ADC; trastuzumab emtansine [T-DM1]), and a small molecule (lapatinib) failed to translate into clinical benefits until the KEYNOTE-811 (first-line) and DESTINY-Gastri01 (≥second-line) trials were conducted. The incorporation of HER2-directed treatment with immune checkpoint inhibitors in the form of a monoclonal antibody or ADC is now approved as a standard treatment. Despite the promising results of new agents (engineered monoclonal antibodies, bi-specific antibodies, fusion proteins, and small molecules) in the early phase of development, the management of HER2-positive gastric cancer requires further optimization to achieve precision medicine with a chemotherapeutic backbone. Treatment resistance is a complex process that can be overcome using a combination of chemotherapy, targeted agents, and immune checkpoint inhibitors, including novel agents. HER2 status must be reassessed in patients undergoing anti-HER2 treatment with disease progression after the first-line treatment. As a general guideline, patients who need systemic treatment should receive chemotherapy plus targeted agents, anti-angiogenic agents, immune checkpoint inhibitors, or their combinations.

  • Based on the Greek myth of Pygmalion and the fairy tale of Cinderella, Shaw's Pygmalion demonstrates a masterful coalescence of these two narrative motifs into a coherent plot scheme. Even more significant is his keen insight into the conflicts created at the tripartite intersection of human activity concerning language/class/culture, which, as the leitmotif, revolves around lessons in language learning. This play basically deals with human transformation and by its very nature, Higgins's experimentation with transforming Eliza cannot stop at language alone. Her cultural transformation ripples over into the realms of gesture and even a unique way of living (modus vivendi) intimately associated with taste and manners, which Bourdieu terms as habitus. By acquiring a new fashion and language, Eliza is reborn as a new lady aspiring to be filled with a newly acquired habitus. While separating her from her old Cockney style, Higgins inculcates Queen's English in Eliza, in which process her changed speech styles gradually transforms and restructures her deportment and manners, finally generating new practices, perceptions and attitudes. The gist of Pygmalion is however less Eliza's ascent into the middle class than her battle for symbolic capital waged at the level of language. By problematizing his contemporary practice of habitus conventionalized and warped by class distinctions based on economic, social and cultural capitals, Shaw creates a new humanist model of man founded on spiritual and rational virtues. In conclusion, Eliza is not a frigid Galatea but a dynamic character that goes through a brilliant transformation of three stages: 1) linguistic; 2) cultural, and 3) humanist. Finally she is built into a "consort battleship" on an equal standing with her sculptor. The process of her character-building cannot be illuminated without resorting to the dynamic notion of habitus, which highlights the process of inculcation, structuring, generation and transposing. Given the overwhelming weight of the heroine's role and the dynamic process of her transformation as the major plot scheme, this play should be christened Galatea in lieu of Pygmalion.

  • As a poet, a reviewer of books, and an editor of a major literary journal, Marianne Moore participated in aesthetic revolution which invented the American poetry of the twentieth century. Of all the modernists, she was one of the few truly technical originals, and became an endearing mascot of poetry. Innately attentive to detail, Moore wrote a myriad of poems about animal and plant subjects, and set out to develope and secure her own particular paradigm for modernist poetic and the poetry of objective and scientific description. Foregrounding a mind scientifically trained, Moore used her verse to demonstrate a means by which to see the reality beyond the obvious. Ironically enough, however, a central difficulty with understanding Moore's poetry lies with her concern for such scientific or surface description and precision. In order to understand Moore's poetry fully, it is of special necessity to appreciate relativity among the seemingly disparate entities such as science and literature, as Moore herself did. This paper explores the way in which the poetic techniques of Moore substantiate her sense of morality that underlies the creation of her poetry. Rather than merely addressing her artistic genius or craftsmanship as a modernist poet, Moore's methods engage the power of imagination, magic, lifting the human spirit and eschewing anthropocentric perspectives. For Moore, the poet's magic comes by diligence. In so doing, as I would argue here, Moore draws on the nature of language, especially what Bakhtin insisted with his notions of polyphony and carnival. By introducing openness to various perspectives and meanings in her verse, Moore succeeds in maintaining her own sense of creativity while continuing to acknowledge morality. In a similar skein, her use of active verbs in animal poems and the kaleidoscopic descriptions demonstrate how Moore accommodates imagination and reality, and form and content.

  • Background: There is increasing evidence that HER2-neu is an important biomarker in gastric carcinomas (GC) and gastroesophageal junction (GEJ) adenocarcinomas. The aim of this study was to evaluate HER2-neu expression and also some clinicopathological features of these neoplasms. Materials and Methods: We selected 211 paraffin-embedded blocks, 193 GC and 18 GEJ. Then 4 micron sections were prepared for staining with hematoxylin and eosin and also for IHC (Her2-neu). The Chi-square test was used for significance between expression of HER2-neu and clinicopathological parameters. Results: In patients with advanced cancer of GC and GEJ, HER2-neu overexpression was more associated with the intestinal cancer subtype. Conclusions: This could be a guide to new complementary therapy for affected patients.

  • The purpose of this paper is to illuminate how Suzan-Lori Parks reveals colonized oppression and violence in a black woman's body in Venus. The body of Hottentot Venus is an 'object' of white male spectators' gazes and a dissection from a medical study. The report on her pathologic anatomy gives the audience the illusion that the body of a black woman is inferior to those of others. Not only 'subjective' aesthetics, but also 'objective' medicine makes us confuse 'fact' with 'truth' about black women. By publicly exhibiting her erotic body, Venus is represented as a singular emblem for nineteenth-century colonial discourse on race and sexuality. Her body stands for the powerful signifier of raped Africa. A distinctive feature of black Venus is her raciality. The ownership of her body is only transferred from Mother-Showman to Doctor Baron. She had no right to her ownership. Her body is an object of hatred and curiosity and at the same time a site which is represented by conflicting desires. Parks' eventual goal in Venus is to investigate 'hindsight' of Venus Hottentot, 'the past' and 'the posterior'. As the meaning of original chocolate can be regained, the insulted and damaged body of Venus should also be recovered and resurrected.

  • Knitwear has become a part of fashion since aristocratic trend-setters of Medieval Spain and France began wearing luxurious silk stockings. However, in more recent times knitwear emerged as a fashion item in the early 20th century when jersey two-piece Channel dresses became popular amongst the French upper classes. Knitwear then evolved into genuine going out clothes through Sonia Rykiel in the 1970s. Sonia Rykiel has made a great contribution to developing knitwear, which she transformed from being used only in informal dresses or clothes for home wear, to a boarder in use in high-quality dresses such as those worn at parties. Unlike most designers who tend to make very different styles each year, she has restricted her clothes to those made with knitwear. The study examined the designs and formative characteristics of her knitwear in order to clarify why Sonia Rykiel's knitwear fashion is apparently so timeless. Results showed that her garments consistently used black oriented color combination, strife patterns, intarsia techniques and application of diversified subordinate materials and other materials that overcome earlier limitations of knitwear. In addition, her designs consistently express the typically Parisian sophisticated urban femininity through practicality, sensuality and playfulness. Overall, her fashion has shown that it exists for women in action through practical design within the scope of demode, the philosophy in her early days, and it has led her to hold great power over knitwear fashion for the past 40 years.

  • This study aims to examine the background to the rise of Rei Kawakubo, a Japanese designer who achieved fame by suggesting the concept of deconstruction and recombination of clothes, and to look at environment of the time, the formative characteristics of her design and the Japanese aesthetic sense inherent in her design. As the method of research, collections that Kawakubo unveiled over the past 10 years starting in 2004 were examined, and a survey of the literature was conducted to describe the background of her growth and the Japanese aesthetic sense inherent in the design. According to the study, Kawakubo grew up in the ruins of a war, and went through a time of great tumult, when Western culture was mixing with Japan's traditional culture. She taught herself a method of creation involving the deconstruction of clothes, and their recombination. For this reason, her design from the beginning was inevitably focused on deconstructing clothes before they could be recombined. Through analyses of her collections, it was found that the formative characteristics of her design were characterized by asymmetry, incompleteness, humor and hybridity. Kawakubo created clothes under the influence of an ethnicity that was shrouded in individuality and a traditional aesthetic sense, and the formative characteristics of her design defined by asymmetry, incompleteness, humor and hybridity were closely related to the hybridity represented by Wabi (わび), Yugen (幽玄), Okashi (をかし) and Zakyo (雜居).

  • The study presented the experience of playtherapy of a 6-yr old girl with elective mutism and attempted to understand her psychopathology and formulated her psychodynamic which was expressed though the therapeutic process of playtherapy in the viewpoint of developmental model. Therapist's attitude was nondirective and supportive. Main theme of her play, fantasy and art was separation anxiety and abandonment fear as the result of continued psychic traumas such as separation from her grandmother and physical abuse by her father and mother etc. So she couldn't achieve developmental tasks such as autonomy and separation individuation and became generally inhibited and selectively mute. The process of play therapy was summarized and coceptualized as her successful progress through sequential developmental phases within the therapeutic relation ship. By reexperiencing this developmental process, she could accomplish her autonomy and separation individuation and developed to oedipal stage and successfully resolve oedipal conflict.

  • This article attempts to explore the literature of Catherine the second, focusing on her comedies in the light of anti-freemasonry in the late 18th-centuryof Russia. Her main idea towards social morals was consistently expressed from in her early comedies during 1770s, such as 'Oh! times!'(1772), to her late counterparts during 1880s, such as so called 'anti-freemason trilogy,' which includes 'the deceiver'(1785), 'the deceived one'(1785) and 'Siberian shaman'(1786). By depicting antagonists-freemasons in her own trilogy, only as alchemists, shamans, fallacious chemists, hypocritical medical doctors, and so on, Caterine the second intended to undermine the mason influence against Russian Empire, which had ideationally attracted Russian nobles and intellectuals and furthermore to reinforce her political control over the intellectuals as well as the public. The above literacy attempts by Catherine can be said to aim to found morals of her own era through the utilization of social discourse, rather than through the political or governmental control.
