Tension-free vaginal tape (TVT) procedure has become one of the most common treatments of female urinary stress incontinence.
Success rates as high as 81.3% were reported over a follow-up period of 7 years. Erosion of the synthetic mesh is a well-described
complication. The mean time for the onset of erosion after sling insertion was 11.2 months. These case reports describe an
erosion of a mid-urethral tape after 18 and 28 months, which is uncommon. There is a need for long-term follow-up of patients
with TVT. 相似文献

Mucosal epithelial cells are infected by a wide variety of pathogens and determining their response to infection is critical for understanding disease pathogenesis. A protocol was developed for culturing primary epithelial cells from fetal bovine intestine and the cultured cells were evaluated for susceptibility to an enteric viral infection. Immunohistochemical staining for cytokeratin confirmed that 60-75% of cultured cells were epithelial cells. Furthermore, following infection with bovine rotavirus (BRV) over 80% of cells in the ileal and jejunal cultures contained viral protein at 16 h post-infection. The intestinal epithelial cell cultures also contained fibroblasts so a jejunal fibroblast culture was established and infected with BRV. Viral protein was detected in jejunal fibroblasts but viral-induced cytopathology was delayed in fibroblast cultures when compared to epithelial cell cultures. This study describes an effective protocol for culturing bovine epithelial cells from fetal intestine and confirmed that the epithelial cells were susceptible to BRV infection. Ileal and jejunal cultures displayed limited growth following continuous passage but early passage epithelial cells provide competent target cells for studying host cell responses to an enteric viral pathogen. 相似文献

GO and nZVI have been used for removing different contaminants from aqueous solution; however, difficulty in the separation of GO, and the aggregation propensity of nZVI particles prevent them from having efficient practical applications. In this study, a green synthesis method was performed to prepare nanohybrids of GO and nZVI to provide an adsorbent with high adsorption efficiency that can be removed from aqueous solution easily by magnetic separation. GO–nZVI nanohybrids were synthesized by using biocompatible cross linkers named 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide (EDC) and N-hydroxysuccinimide (NHS). The effect of the nZVI ratio in the synthesized nanohybrids was studied at three different ratios of GO : nZVI, 1 : 1, 1 : 5 and 1 : 10. SEM/EDS, HRTEM, STEM/EDS, XRD, Raman, FTIR, and TGA analyses were conducted to provide physical and chemical properties of the adsorbents. The performance of nZVI and GO–nZVI nanohybrids as an adsorbent have been studied for methylene blue (MB) removal from an aqueous solution with an initial concentration of 12 mg L−1 at adsorbent dosages of 0.1, 0.3, 0.5, and 1 mg mL−1. Results indicated that GO–nZVI (1 : 5) provided the highest MB removal (99.1%) by using 10 mL of the 1 mg mL−1 adsorbent. After regeneration of the GO–nZVI (1 : 5) nanohybrids with ethanol, 84.3%, 67.2%, and 63.0% of MB removal were achieved in the first to third regeneration cycle. Results also showed that the GO–nZVI nanohybrids were not affected by aggregation compared to nZVI.A green synthesis method was used to prepare GO–nZVI nanohybrids to provide an adsorbent with high adsorption efficiency that can be removed from aqueous solutions easily by magnetic separation. 相似文献

During the period January 1983 to September 1993, 36 patients of Nasal Cavity, Ethmoid / Sphenoid Sinus Cancers were treated at Radiotherapy Department, Medical College. Calcutta. All were treated by irradiation alone. Local control was achieved in about 50% of cases at 6 weeks following completion of treatment. Informations with respect to tumour extension to suspected areas of spread, are very much necessary for accurate Radiotherapy treatment planning and for this reason C.T. Scan imaging is mandatory in pre-treatment work-up of NES Complex cancers. Precision Radiotherapy with utmost care to avoid or lessen Radiation dose to optic nerve, is the most suitable method of treatment for our patients. Stringent and prolonged follow-up necessary to know the treatment outcome as the tumours of NES Complex are characterised by ‘delayed recurrence’. 相似文献

Antibodies specific to cholesterol was first reported in 1925. It may develop in the body naturally and it is believed that this antibody has a protective role against harmful forms of cholesterol, such as LDL & VLDL. An immunoglobulin protein, anticholesterol may be found in both circulation as well as digestive tract. Many studies have been done on anticholesterol antibody. Our immune system may produce anticholesterol antibodies in response to elevated levels of cholesterol rich particles, such as LDL & VLDL. It can be induced in animals by conjugating or incorporating the cholesterol antigen into a variety of structures. Immunization markedly decreases the risk of developing atherosclerosis. In comparison to non-tumorous normal subject, the antibody is found to be significantly higher in non-small cell lung cancer (NSCLC). Elevated anti-cholesterol antibodies might be applicable for the serodiagnosis of NSCLC. Some studies showed that LDL immunization induces T-cell dependent antibody formation that protects atherosclerosis. Origo Biosciences scientists had identified a dietary antibody to cholesterol. This protein, when ingested, binds to cholesterol in the human digestive tract and blocks its absorption into the bloodstream. These studies may lead to us to realize the importance of anticholesterol and to find the way for reduction of hypercholesterolemia and thereby reduction of morbidity and mortality. 相似文献
