Recognition of body image and food behavior factors among middle school students in San Francisco area

The purpose of this study was to determine the recognition of body image and food behavior factors according to the BMI. The subjects of this study were 242 7th grade students resided in San Francisco area. The degree of recognition for self-estimated physique of subjects by gender and by race showed no significant differences by gender but significant differences by race, showing that 20.0% was considered as underweight in Asian and 7.5% was considered as underweight in White students. This showed the same tendency as actual physique status (BMI). Also, the ratio of being recognized as more than overweight was 17.3% in Asian, 23.3% in Hispanic, and 13.4% in White students. In case of female students, the ratio of dieting experience was 63.3%, and 49.3% of White students and 63.3% of Hispanic students experienced dieting. In case of students answered not healthy, their body weight were significantly higher than those answered as healthy, and the BMI was also over 19, showing significant differences. Thus cases that answered as not healthy had greater body weight and BMI. Also it showed that frequent dieting experience is related to higher height and weight. The analysis of food behavior factors perceived by body shape showed that the group perceived itself as overweight consumed more 'fast food' but had low scores in 'vegetables' intake, with frequent intake of 'soda' and tendency to 'overeat'. Also, the tendency for 'balanced life' was significantly lower and for skipping breakfast was significantly higher, suggesting problematic food behavior

Stenting of the Left Main Coronary Artery in a Patient With Takayasu's Arteritis

Management of Takayasu's arteritis of the left main coronary artery (LMCA) is difficult because of the possibility of restenosis. Clinically significant stenotic lesions must be considered anatomical correlation. Many studies have reported that the management of stenotic lesions of the LMCA with endoluminal stenting and balloon angioplasty and de-novo stenting is safe and effective for patients with Takayasu's arteritis. We report the case of a patient with Takayasu's arteritis of the LMCA. The patient had undergone two consecutive percutaneous coronary interventions because of recurrent restenosis of in-stent lesions, and eventually underwent coronary artery bypass graft (CABG) surgery for myocardial infarction in the same lesion. We suggested treatment with CABG because the pathophysiology of Takayasu's arteritis is different from that of atherosclerotic stenosis

Acute Chylous Peritonitis Mimicking Ovarian Torsion in a Patient with Advanced Gastric Carcinoma

The extravasation of chyle into the peritoneal space usually does not accompany an abrupt onset of abdominal pain with symptoms and signs of peritonitis. The rarity of this condition fails to reach preoperative diagnosis prior to laparotomy. Here, we introduce a case of chylous ascites that presented with acute abdominal pain mimicking peritonitis caused by ovarian torsion in a 41-yr-old female patient with advanced gastric carcinoma. An emergency exploratory laparotomy was performed but revealed no evidence of ovarian torsion. Only chylous ascites was discovered in the operative field. She underwent a complete abdominal hysterectomy and salphingo-oophorectomy. Only saline irrigation and suction-up were performed for the chylous ascites. The postoperative course was uneventful. Her bowel movement was restored within 1 week. She was allowed only a fat-free diet, and no evidence of re-occurrence of ascites was noted on clinical observation. She now remains under consideration for additional chemotherapy

The Rhizomes of Acorus gramineus and the Constituents Inhibit Allergic Response In vitro and In vivo

The rhizomes of Acorus gramineus have frequently been used in traditional medicine mainly for sedation as well as enhancing brain function. In this study, the anti-allergic activity of A. gramineus was investigated. The 70% ethanol extract of the rhizomes of A. gramineus was found to inhibit the allergic response against 5-lipoxygenase (5-LOX)-catalyzed leukotriene (LT) production from rat basophilic leukemia (RBL)-1 cells and β-hexosaminidase release from RBL-2H3 cells with IC50's of 48.9 and >200 μg/ml, respectively. Among the 9 major constituents isolated, β-asarone, (2R,3R,4S,5S)-2,4-dimethyl-1,3-bis (2',4',5'-trimethoxyphenyl)tetrahydrofuran (AF) and 2,3-dihydro-4,5,7-trimethoxy-1-ethyl-2-methyl-3-(2,4,5-trimethoxyphenyl)indene (AI) strongly inhibited 5-LOX-catalyzed LT production in A23187-treated RBL-1 cells, AI being the most potent (IC50=6.7 μM). Against β-hexosaminidase release by antigen-stimulated RBL-2H3 cells, only AI exhibited strong inhibition (IC50=7.3 μM) while β-asarone and AF showed 26.0% and 39.9% inhibition at 50 μM, respectively. In addition, the ethanol extract of A. gramineus showed significant inhibitory action against the hapten-induced delayed hypersensitivity reaction in mice by oral administration at 200 mg/kg. Therefore, it is suggested that A. gramineus possesses anti-allergic activity and the constituents including β-asarone and AI certainly contribute to the anti-allergic activity of the rhizomes of A. gramineus.This study was financially supported by the research fund of Studies on the Identification of the Efficacy of Biologically Active Components from Oriental Herbal Medicines from Korean Food and Drug Administration (2009-2011) and post-BK21 project from the Ministry of Education, Korea.OAIID:oai:osos.snu.ac.kr:snu2013-01/102/0000001731/23SEQ:23PERF_CD:SNU2013-01EVAL_ITEM_CD:102USER_ID:0000001731ADJUST_YN:NEMP_ID:A000864DEPT_CD:371CITE_RATE:.794FILENAME:bt_asarone.pdfDEPT_NM:제약학과EMAIL:[email protected]_YN:YCONFIRM:

EFFECTIVE DOSE MEASUREMENT FOR CONE BEAM COMPUTED TOMOGRAPHY USING GLASS DOSIMETER

During image-guided radiation therapy, the patient is exposed to unwanted radiation from imaging devices built into the medical LINAC. In the present study, the effective dose delivered to a patient from a cone beam computed tomography (CBCT) machine was measured. Absorbed doses in specific organs listed in ICRP Publication 103 were measured with glass dosimeters calibrated with kilovolt (kV) X-rays using a whole body physical phantom for typical radiotherapy sites, including the head and neck, chest, and pelvis. The effective dose per scan for the head and neck, chest, and pelvis were 3.37±0.29, 7.36±0.33, and 4.09±0.29 mSv, respectively. The results highlight the importance of the compensation of treatment dose by managing imaging dose

Laparoscopic Enucleation of a Nonfunctioning Neuroendocrine Tumor of the Pancreas

Laparoscopic approaches are increasingly used in pancreatic surgery. In the treatment of neuroendocrine tumors (NETs) of the pancreas, enucleation is one of the recommended surgery. Although many clinical experiences have reported the safety and efficacy of laparoscopic enucleation of functioning NETs, such as insulinomas, few reports have explored such treatment for non-functioning NETs. Here, we present a case of 70-year old female patient who underwent successful laparoscopic enucleation of a nonfunctioning NET located in the body of the pancreas

Optimization of the Sampling Periods and the Quantization Bit Lengths for Networked Estimation

This paper is concerned with networked estimation, where sensor data are transmitted over a network of limited transmission rate. The transmission rate depends on the sampling periods and the quantization bit lengths. To investigate how the sampling periods and the quantization bit lengths affect the estimation performance, an equation to compute the estimation performance is provided. An algorithm is proposed to find sampling periods and quantization bit lengths combination, which gives good estimation performance while satisfying the transmission rate constraint. Through the numerical example, the proposed algorithm is verified
