Poster Session:PS 0578 ; Oncology : Recurred Maxillary Sinus Cancer with only Adrenal Metastasis
( Friederika Fluck ),( Luiz Menezes Falcao ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1
Maxillary sinus cancers are rare tumors. Patients with maxillary sinus cancers tended to be asymptomatic until they invade adjacent structures, and then they often presented with locally advanced disease. Within a year since treatment completion, tumor recurrences were commonly occurred with locoregional failure. Relatively fewer patients presented a distant metastasis and the most commonly involved metastatic sites were lung and bone. Here, we report a rare case of recurred maxillary sinus cancer with only adrenal gland metastasis. A 64-year-old man had been treated for the odontogenic sinusitis through the dental caries on palatal root of #26. We extracted his tooth #26 and prescribed oral antibiotics for the past 3 weeks. Although he had took antibiotics, he was still complained about painful swelling in the left submandibular area and it extended to the left maxillary sinus. Upon intraoral examination, we found a granulation tissue was protruded at the tooth #26 extraction site and we performed a biopsy at that site. Histological examination revealed a poorly differentiated squamous cell carcinoma. Computerized tomography (CT) and positron emission tomography (PET)/CT were performed for tumor staging. We concluded he had a maxillary sinus squamous cell carcinoma stage IVA (cT3N2) by American Joint Committee on Cancer (AJCC 7th ed.). The patient had received left partial maxillectomy and left radical neck dissection followed by postoperative chemoradiotherapy (CCRT). One month later since completion of CCRT, we assessed primary tumor status by Neck CT. There was no oral and neck lesions. We took Neck CT and Chest CT 2 months later. There was still no locoregional recurrence but presented a newly developed left adrenal mass. He had received a laparoscopic left adrenalectomy and histological result showed a poorly differentiated squamous cell carcinoma. Then we delivered him a palliative chemotherapy.
De novo Regeneration of Fertile Common Bean (Phaseolus vulgaris L.) Plants
Albino Margareth M.C.,Vianna Giovanni R.,Falcao Rosana,Aragao Francisco J.L. The Korean Society of Plant Biotechnology 2005 Plant molecular biology and biotechnology research Vol.7 No.4
Common bean (Phaseolus vulgaris L.) plants were regenerated via organogenesis from mature embryonic axes, cultured on MS medium supplemented with ildole-3-ecetic acid (IAA) and thidiazuron (TDZ) for one week in the dark. Embryonic axillary regions were excised, longitudinally cut to split the both sides, and cultured for two weeks on MS medium supplemented with IAA and TDZ. The combination 0.5 mg $l^{-1}$ TDZ/0.5 mg $l^{-1}$ IAA presented the higher efficiency in shoot regeneration and the combination 0.5 mg $l^{-1}$ TDZ/0.25 mg $l^{-1}$ IAA presented the higher efficiency in conversion of shoots to plants. Regenerating explants were transferred to MS medium containing 1 mg $l^{-1}$ BAP for shoot development. All elongated shoots were rooted in vitro, presented normal phenotype and produced viable seeds. Histological analysis confirmed the mode of regeneration as de novo shoot organogenesis.
Student-Athletes’ Development of Life Skills in a University Sport Setting
Marie-Christine Chartier,William R. Falcao,Christiane Trottier 한국코칭능력개발원 2021 International Journal of Coaching Science Vol.15 No.2
University sports have unique characteristics that can impact life skills development and transfer during a crucial developmental period of a person’s life. Thus, it is important to investigate how sport participation can impact life skills development in university student-athletes. The purpose of this study was therefore to examine the experiences of student-athletes in a university sport setting and to explore how this environment facilitated life skills development and transfer. Based on a multiple-case study design, four senior student-athletes participated in two individual semi-structured interviews. A cross-case analysis revealed that the contextual demands of university sports encouraged the development and perfecting of student-athletes life skills throughout their time at university. These results highlight that a positive climate created by the coaches and the naturally occurring contextual demands of university sports are fundamental aspects to consider when promoting life skills development and transfer.
