| 1 | Small bowel tumors detected and missed during capsule endoscopy: Single center experience显示文摘AIM:To characterize small bowel(SB)tumors detected by capsule endoscopy(CE),and identify missed tumors.METHODS:The study included 145 consecutive patients in whom 150 CEs were performed.Following CE,the medical records of the study population were reviewed.Results of double-or single-balloon enteroscopy performed after CE and the results of surgery in all patients operated on were retrieved.The patients were contacted through telephone interviews or postal mail.In addition,the national cancer registry and the polish clinical gastrointestinal stromal tumor(GIST)Registry were searched to identify missed neoplasms.RESULTS:Indications for CE included overt and occult obscure gastrointestinal bleeding(n=81,53.7%),anemia(n=19,12.7%),malabsorption(n=18,12%),abnormal CB follow through(n=9,6%),abdominal pain(n=7,5%),celiac disease(n=5,3%),neuroendocrine tumor(n=3,2%),Crohn’s disease(n=2,<2%),Peutz-Jeghers syndrome(n=2,<2%),other polyposes(n=2,<2%),and diarrhea(n=2,<2%).The capsule reached the colon in 115(76.6%)examinations.In 150 investigations,CE identified 15SB tumors(10%),14 of which were operated on or treated endoscopically.Malignancies included metastatic melanoma(n=1),adenocarcinoma(n=2),and GIST(n=3).Benign neoplasms included dysplastic Peutz-Jeghers polyps(n=4).Non-neoplastic masses included venous malformation(n=1),inflammatory tumors(n=2),and a mass of unknown histology(n=1).During the follow-up period,three additional SB tumors were found(2 GISTs and one mesenteric tumor of undefined nature).The National Cancer Registry and Polish Clinical GIST Registry revealed no additional SB neoplasms in the post-examination period(follow-up:range 4.2-102.5 mo,median 39 mo).The sensitivity of CE for tumor detection was 83.3%,and the negative predictive value was 97.6%.The specificity and positive predictive value were both 100%.CONCLUSION:Neoplasms may be missed by CE,especially in the proximal SB.In overt obscure gastrointestinal bleeding,complementary endoscopic and/or radiologic diagnostic tests are indicated. | Edyta S Zagorowicz Anna M Pietrzak Ewa Wronska Jacek Pachlewski Piotr Rutkowski Ewa Kraszewska Jaroslaw Regula | 2013 | World Journal of Gastroenterology2013，19，47： | 10 |
| 2 | Theoretical simulation of T2SLs InAs/GaSb cascade photodetector for HOT condition显示文摘The investigation of the interband type-II superlattice In As/Ga Sb cascade photodetector in the temperature range of 320–380 K is presented. The article is devoted to the theoretical modeling of the cascade detector characteristics by the use of the Simu Apsys platform and the 4-band model(k?p 8 × 8 method). The obtained theoretical characteristics are comparable with experimentally measured ones, suggesting that transport in the absorber is determined by the dynamics of intrinsic carriers and by their lifetime. An overlap equal to 120 me V was used in calculations and a correction term in the 'non-common atom' model H_(xy) = 700 me V was added to the Hamiltonian. The electron and hole effective masses from dispersion curves were estimated and absorption coefficient α was calculated. Based on the simulation detectivity, D* characteristics in the temperature range 320–380 K were calculated. The simulated theoretical characteristics at 320 K are comparable to experimentally measured ones, however at higher temperatures, the experimental value of D* does not reach the theoretical values due to the low resistance of the device and short diffusion length. | Tetiana Manyk Klaudia Hackiewicz Jaroslaw Rutkowski Piotr Martyniuk | 2018 | Journal of Semiconductors2018，39，9： | 2 |

| 10 | The Nutritional Value of Yellow Lupine (Lupinus luteus)for Growing Pigs显示文摘The aim of the study was a comparison of the composition and apparent total tract digestibility (ATTD) of nutrients in the seeds of two varieties of yellow lupine (YL). Moreover, an examination of the level of soybean meal (SBM) substitution by YL meal and in a combination with rapeseed meal (RSM) on the pigs’ performance was performed. In a digestibility trial, 30 male pigs were tested using a marker method. In two growth experiments, 60 pigs (in each) were fed diets where SBM was replaced by YL in 0%, 20%, 40%, 60%, 80% and 100% or by a mixture of RSM and YL or by both these components. The chemical composition of varieties differed among crude protein (CP), fiber, acid detergent fiber (ADF), neutral detergent fiber (NDF) and fat. The digestibility coefficients of protein, fat and gross energy were similar for both varieties. The substitution of SBM with YL did not negatively affect the pigs’ performance. A mixture of RSM with YL had no negative effect on growth parameters, except for the starter phase, when a level of above 15% RSM in the diet reduced the pigs’ gains. In conclusion, YL alone and with RSM may be a sustainable alternative to SBM in pig nutrition. | Anita Zaworska-Zakrzewska Malgorzata Kasprowicz-Potocka Piotr Nowak Zuzanna Wisniewska Andrzej Rutkowski | 2019 | Journal of Agricultural Science and Technology(A)2019，9，6： | 0 |
