Radiotherapy (RTx) is a highly effective treatment for head and neck cancer that can cause concurrent damage to surrounding healthy tissues. In cases of nasopharyngeal carcinoma (NPC), the auditory apparatus inevitably exposed radiation fields sustains considerable damage, resulting in dysfunction. To date, little research has been conducted on changes induced by RTx middle ear underlying mechanisms involved. Dexamethasone (DEX) widely used clinical practice because its immunosuppressive...
The usefulness of (18)F-FDG PET in gastric cancer recurrence is limited by low sensitivity. Given that detectability dependent on the tumor's metabolic characteristics, we tested whether performance for enhanced patients with (18)F-FDG-avid primary tumors.Three hundred sixty-eight advanced underwent PET/CT initial staging and surveillance after curative surgery. On PET/CT, tumors were if they displayed focal uptake an SUVmax 4 or more. Follow-up was evaluated recurrent disease.On tumor 236...
Abstract Positron emission tomography/computed tomography (PET/CT) with 18 F-fluorodeoxyglucose (FDG) is widely used for management of nasopharyngeal carcinoma (NPC). Combining the radiomic features pre- and post-treatment FDG PET images may improve tumor characterization prognostic predication. We investigated value from post-radiotherapy in patients NPC. Quantitative primary tumors were extracted 145 NPC delta values also calculated. The study population was divided randomly into two...
Natural resistance-associated macrophage protein 1 (Nramp1) is a genetic locus associated with innate resistance or susceptibility of murine hosts to infection intracellular pathogens such as Salmonella, Leishmania and Mycobacterium. The human homologue the Nramp1 gene, designated NRAMP1, has been investigated candidate gene for autoimmune diseases well infections. This study tries determine whether NRAMP1 polymorphisms are rheumatoid arthritis in Koreans. nine (1 microsatellite, variation...
Abstract This study aimed to evaluate the frequency of nodal metastases and disclose diagnostic performance endoscopic ultrasonography (EUS) PET/CT in T N staging surgically resected early‐stage esophageal squamous cell carcinomas (eSCCs). Institutional review board approved this retrospective with waiver informed consent for reviewing medical record. We included 435 patients an early T‐stage (Tis or T1a [≤T1a], T1b T2) eSCC . The rates metastatic lymphadenopathy were calculated. Then, EUS...
Cisplatin is a life-saving anticancer compound used to treat multiple solid malignant tumors, while it causes permanent hearing loss. There no known cure, and the FDA has not approved any preventative treatment for cisplatin-based ototoxicity. This study investigated whether carbon monoxide (CO)-releasing tricarbonyldichlororuthenium (II) dimer, CORM-2, reverses cisplatin-induced impairment reduces cisplatin accumulation in mouse inner ear. Male 6-week-old BALB/c mice were randomly assigned...
The objectives of this project were to (a) assess hypertension and diabetes screening data collection practices guidelines (b) develop test standardized forms for use at minority community- faith-based events. Project Phase I involved resource assessment the development a set containing core both diabetes. These then tested during II predetermined communitybased events throughout United States. Community- health programs are important in reaching informing individuals selected communities...
Summary Aim: We evaluated the association between intestinal visualization on bone scintigraphy and IV CT contrast in patients with breast cancer. Patients, methods: 452 cancer underwent a 99mTc methylene diphosphonate (MDP) scan for surveillance of metastasis. Presence, site intensity uptake were visually assessed. For visualization, medical records reviewed to identify alleged potential causes. When was administrated same day as scan, time injection, MDP administration Results: Intestinal...
The purpose of this article is to examine how, in the context university admission strategy, private tutoring expenditure affected by household income and academic achievement levels. To end, impact strategy on was analyzed using Gyeonggi Education Panel Study 7-9th data. mitigate selection bias while choosing strategies, study used a correction term scrutinize strategies expenditure. results analyses are as follows. First, where early being pursued, reduced average, compared those following...

This study aimed to compare policy effects of two main pillars national financial aid programs—student loans and scholarships—operating under the shared objective assistance for higher education but in different ways, focusing on university students’ outcomes, student life, leisure, quality life. We utilized data from KEEP II covering 2018~2021. The identified groups receiving scholarships through Korea Student Aid Foundation (KOSAF), employing propensity score matching (PSM) control sample...
Introduction: The outcome of advanced gastric cancer remains poor, and early detection recurrence is important. FDG PET/CT known to be useful in recurrent cancer, but the specific indication for surveillance with following curative resection unclarified date. In this study, we evaluated relation between uptake primary tumor patterns disease cancer. And investigated whether FDG-avid tumors are associated improved performance detecting Methods: Subjects were 372 patients (mean age 57.3 ± 11.5...
Pheochromocytomas (PHEOs) are chromaffin cell-derived adrenal tumors. 6-[ 18 F]-L-fluoro-L-3, 4-dihydroxyphenylalanine ( F-FDOPA) is a radiotracer taken up in neuroendocrine cells via the L-type amino-acid transporter. F-FDOPA useful patients with PHEO. However, more information about use of PET/CT scan needed. Thus, current study investigated various PET parameters on preoperative scan.The findings 29 who underwent adrenalectomy after scans were evaluated according to their pathologic...
