국외논문정보 - 에폭시/카본나노튜브 나노복합물 생산 중 방출되는 입자의 특성 및 관리
Cena, Lorenzo G.,Peters, Thomas M. 대한산업보건협회 2011 산업보건 Vol.279 No.-
이 논문은 나노물질을 다룰 때 발생하는 나노입자에 대한 특성과 관리방안 중 하나인 환기시설의 효과에 대하여 연구한 논문이다. 나노관련 연구는 아직 명확한 건강상 영향이 체계적으로 기술되어 있지는 않지만 산업보건에서는 새로운 분야이고 많은 연구가 이루어지지 않았기에 향후 우리나라도 연구가 필요할 것으로 판단되어 소개하고자 한다.

JEON, Sunghoon,KWON, Seong Young,CENA, Rohani,LEE, Ju-hwan,CHO, Kyoung-Oh,MIN, Jung-Joon,CHOI, Jihye The Japanese Society of Veterinary Science 2014 The Journal of veterinary medical science Vol.76 No.7
<P><B>ABSTRACT</B></P><P>A 12-year-old spayed female Yorkshire Terrier with intermittent vomiting was diagnosed with regional granulomatous enteritis through histopathological examination. On ultrasonography and computed tomography, a focal thickened duodenal wall showed a mass-like appearance with indistinct wall layers. Marked uptake of <SUP>18</SUP>F-fluorodeoxyglucose was observed from the mass on positron emission tomography-computed tomography. Regional granulomatous enteritis is a rare form of inflammatory bowel disease and may have imaging features similar to intestinal tumors. This is the first study describing the diagnostic imaging features of ultrasonography, computed tomography and positron emission tomography-computed tomography for regional granulomatous enteritis in a dog.</P>

<P><B>ABSTRACT</B></P><P>A 10-year-old, intact female Yorkshire terrier had multiple pulmonary nodules on thoracic radiography and ultrasonography with no lesions elsewhere. Computed tomography (CT) and positron emission tomography and computed tomography (PET-CT) using 18F-fluorodeoxyglucose (FDG) were performed to identify metastasis and undetected primary tumors. On CT examination, pulmonary nodules had a hypoattenuating center with thin peripheral enhancement, suggesting ischemic or necrotizing lesion. In PET-CT at 47 min after intravenous injection of 11.1 MBq/kg of FDG, the maximum standardized uptake value of each pulmonary nodule was about from 3.8 to 6.4. There were no abnormal lesions except for four pulmonary nodules on the CT and PET-CT. Primary lung tumor was tentatively diagnosed, and palliative therapy using 2 mg/kg tramadol and 2.2 mg/kg carprofen twice per day was applied. After the dog’s euthanasia due to deteriorated clinical signs and poor prognosis, undifferentiated pulmonary adenocarcinoma was diagnosed through histopathologic and immunochemistry examination. To the best of the authors’ knowledge, this is the first study of CT and PET-CT features of canine pulmonary adenocarcinoma. In this case, multiple pulmonary adenocarcinoma could be determined on the basis of FDG PET-CT through screening the obvious distant metastasis and/or lymph node invasions and excluding unknown primary tumors.</P>
Coexistence of Excessive Weight Gain and Celiac Disease in Children: An Unusual Familial Condition
Valeria Calcaterra,Corrado Regalbuto,Alexandra Madè,Mariasole Magistrali,Maureen M. Leonard,Hellas Cena 대한소아소화기영양학회 2019 Pediatric gastroenterology, hepatology & nutrition Vol.22 No.4
Excessive weight gain in children diagnosed with celiac disease (CD) is becoming more common. We describe 2 siblings (9-year and 6 months-old female and 6-year and 9 monthsold male) with obesity showing attenuated gastrointestinal and atypical symptoms in which CD was diagnosed in the absence of a known family history of CD. After children's diagnosis, CD in their parents was also investigated. It was detected in their father affected by overweight. The presentation of patients with CD has changed. While patients with overweight and obesity commonly have symptoms such as abdominal pain, reflux, headache, and constipation due to lifestyle factors, CD should also be considered in patients with or without a family history of CD. Careful nutritional status assessment and follow-up monitoring after the diagnosis of CD are mandatory, especially in subjects who are already overweight at the presentation of this disease.

<P>Direct interspecies transmissions of group A rotaviruses (RVA) have been reported under natural conditions. However, the pathogenicity of RVA has never been directly compared in homologous and heterologous hosts. The bovine RVA/Cow-tc/KOR/K5/2004/G5P[7] strain, which was shown to possess a typical porcine-like genotype constellation similar to that of the G5P[7] prototype RVA/Pig-tc/USA/OSU/1977/G5P9[7] strain, was examined for its pathogenicity and compared with the porcine G5P[7] RVA/Pig-tc/KOR/K71/2006/G5P[7] strain possessing the same genotype constellation. The bovine K5 strain induced diarrhea and histopathological changes in the small intestine of piglets and calves, whereas the porcine K71 strain caused diarrhea and histopathological changes in the small intestine of piglets, but not in calves. Furthermore, the bovine K5 strain showed extra-intestinal tropisms in both piglets and calves, whereas the porcine K71 strain had extra-intestinal tropisms in piglets, but not in calves. Therefore, we performed comparative genomic analysis of the K71 and K5 RVA strains to determine whether specific mutations could be associated with these distinct clinical and pathological phenotypes. Full-length sequencing analyses for the 11 genomic segments for K71 and K5 revealed that these strains were genetically nearly identical to each other. Two nucleotide mutations were found in the 5′ untranslated region (UTR) of NSP5 and the 3′ UTR of NSP3, and eight amino acid mutations in VP1-VP4 and NSP2. Some of these mutations may be critical molecular determinants for RVA virulence and/or pathogenicity.</P>
