This report describes a primary central nervous system B-cell lymphoma in a 3-year-old intact female Maltese dog. Canine primary central nervous system lymphomas constitute about 4% of all intracranial primary neoplasms, but comprehensive histopathologic classifications have rarely been carried out. This is the first report of this disease in a young adult dog.  相似文献   

Correlation of Foxp3 positive regulatory T cells with prognostic factors in canine mammary carcinomas     

Kim JH  Hur JH  Lee SM  Im KS  Kim NH  Sur JH 《Veterinary journal (London, England : 1997)》2012,193(1):222-227

Regulatory T cells (Treg) cells play a crucial role in tumor progression by suppressing anti-tumor immunity, but are not well-documented in veterinary oncology. To identify the characteristics of Treg cells in tumor microenvironments, the numbers of Treg cells were analyzed and compared with histological prognostic factors and molecular biomarkers in canine mammary carcinoma (MC) tissues (n=37). Abundant Treg cells were associated with high histological grade and lymphatic invasion. The numbers of Treg cells infiltrating intratumoral areas markedly increased in tumors with poor prognostic factors, such as high histological grade, lymphatic invasion, and necrosis. These findings suggest that Treg cells play a role in canine MC progression. Furthermore, Treg cell numbers in intratumoral compartments may provide a potential prognostic factor when assessing canine MCs, which may in turn lead to the development of new immunologic therapeutics.  相似文献   

Simulations of storm hydrographs in a mixed-landuse watershed using a modified TR-20 model   总被引：1，自引：0，他引：1  

T.I. Jang  H.K. Kim  S.J. Im 《Agricultural Water Management》2010,97(2):201-207

Most flood damage in Korea is caused by heavy rainfall events and typhoons during the summer rainy season. A modified Natural Resources Conservation Service (NRCS) TR-20 model, TR-20-RICE, was developed to investigate the storm runoff characteristics of a 385-ha mixed-landuse watershed in Korea. The TR-20-RICE not only used the rainfall excess and hydrologic flood routing components of the original TR-20 model, but also included a paddy runoff process, which captured irrigated paddy runoff characteristics such as inundation, retention storage, and surface runoff. The performances of TR-20 and TR-20-RICE were compared using storm hydrographs and observational data. The results indicated that both models simulated storm runoff accurately over the simulation period. The TR-20-RICE runoff volume, peak discharge, and time-to-peak predictions were slightly closer to observations than those of the TR-20. The TR-20-RICE model may an effective alternative to the TR-20 model for generating storm hydrographs, particularly in the mixed-landuse watershed in Korea.  相似文献   

Liquid handling properties of hollow viscose rayon/super absorbent fibers nonwovens for reusable incontinence products     

Ga Hee Kim  Ji Ho Youk  Yoon Jin Kim  Jung Nam Im 《Fibers and Polymers》2016,17(7):1104-1110

To develop reusable incontinence products, blend nonwovens of hollow viscose rayon (HVR) and super absorbent fibers (SAFs) were prepared using a needle-punching process and their liquid handling properties, such as the fluid absorption capacity, fluid retention capacity, fluid absorption under load, moisture evaporation rate, and repeated water absorption were investigated. As the SAF content in the HVR/SAF blend nonwovens was increased, the fluid absorption capacity, fluid retention capacity, and fluid absorption under load increased, whereas the moisture evaporation rate decreased. SAF had a more significant effect on fluid retention than fluid absorption. In the case of HVR/SAF(8/2) and HVR/SAF(7/3), more than 100 % of the fluid absorption capacity was retained even after 5 cycles of repeated water absorption tests. Overall, the HVR/SAF blend nonwovens are good candidates for reusable incontinence products.  相似文献   

Preparation and characterization of carboxymethyl cellulose nonwovens by a wet-laid process     

Min Ji Yoon  Song Jun Doh  Jung Nam Im 《Fibers and Polymers》2011,12(2):247-251

In this study, micro-porous carboxymethyl cellulose (CMC) nonwovens were prepared by carboxymethylation of cellulose nonwovens produced by a wet-laid process and their properties were investigated for potential applications as adhesion prevention barriers. After carboxymethylation, the thickness and mean pore size of the cellulose nonwovens were increased, whereas their pore size distribution became narrower. Tensile strength of cellulose nonwovens was proportional to basis weight, and dramatically increased after carboxymethylation. CMC nonwovens immediately absorbed a phosphate buffered saline solution and showed swollen phase within 1 min. It was found that the thickness and pore size distribution of CMC nonwovens could be easily controlled by the wet-laid process. It is expected that the CMC nonwovens can be used as adhesion prevention barriers.  相似文献   

Preparation of poly(vinyl alcohol)/ZrO2 composite nanofibers via co-axial electrospinning with higher ZrO2 particle content     

Young Min Im  Tae Hwan Oh  Jin Wook Cha  Young Ho Seo  Jun Sung Hwang  Joseph A. Nathanael  Sung Soo Han  Soon Ho Jang 《Fibers and Polymers》2014,15(10):2066-2071

Poly(vinyl alcohol) (PVA)/zirconium oxide (ZrO₂) composite nanofibers with a skin-core structure were prepared and the effect of ZrO₂ particle content on uniform web formation was investigated. The optimized polymer concentration, tip to collector distance, and applied voltage for electrospinning were 11 wt%, 12 cm, and 20 kV, respectively. Skin-core PVA/ZrO₂ composite nanofibers containing up to 12 wt% ZrO₂ were successfully prepared, but it was difficult to obtain PVA/ZrO₂ composite nanofiber webs via conventional electrospinning. Increasing the amount of ZrO₂ caused the morphology of the PVA/ZrO₂ composite nanofibers to become a non-uniform nanoweb with irregular nanofiber diameters. While it was difficult to obtain a uniform nanofiber web containing a content of ZrO₂ over 6 wt% for conventional electrospinning, a more uniform nanofiber web could be obtained at up to 9 wt% ZrO₂ using a skin-core dual nozzle. More uniform webs could also be obtained when ZrO₂ was in the skin rather than the core.  相似文献   

Prediction of parturition date in the bitch and queen     

Michel E  Spörri M  Ohlerth S  Reichler I 《Reproduction in domestic animals》2011,46(5):926-932

Assessment of gestational age and parturition date prediction is a challenging, yet common task in clinical management of the pregnant bitch or queen. Knowing the approximate parturition date is essential for a thorough pregnancy monitoring. Radiographic and ultrasonographic methods are suitable in bitches and queens. In the bitch, moreover, ovulation timing by means of LH or progesterone assay, determination of onset of vaginal dioestrus by means of examination of vaginal cytology, and recognition of impending parturition by monitoring prepartal progesterone levels and body temperature variation are practical methods. A combination of different methods increases the accuracy of parturition date prediction.  相似文献   

Simultaneous determination of orysastrobin and its isomers in rice using HPLC-UV and LC-MS/MS     

Kwon CH  Lee YD  Im MH 《Journal of agricultural and food chemistry》2011,59(20):10826-10830

Orysastrobin is a new strobilurin-type fungicide to control leaf and panicle blast and sheath blight in rice. An analytical method was developed to determine the residues of orysastrobin and its two isomers, the main metabolite F001 and the major impurity F033, in hulled rice by the use of high-performance liquid chromatography with ultraviolet photometry (HPLC-UV) and liquid chromatography with tandem mass spectrometry (LC-MS/MS). All compounds were extracted with acetone from hulled rice samples. The extract was diluted with saline water, and an extraction step using dichloromethane/n-hexane partition was used to recover analytes from the aqueous phase. An n-hexane/acetonitrile partition and Florisil column chromatography were employed to further remove interfering coextractives prior to instrumental analysis. An octadecylsilyl column was successfully applied to identify orysastrobin and its isomers in sample extracts. Net recovery rates of orysastrobin, F001, and F033 from fortified samples ranged from 80.6 to 114.8% using HPLC-UV and LC-MS/MS. Relative standard deviations for the analytical methods were all <20%, and the quantification limits of the method were in the 0.002-0.02 mg/kg range. The proposed methods were reproducible and sufficiently accurate to evaluate the terminal residue of orysastrobin and its isomers in rice.  相似文献
