Visna DNA synthesis and the tempo of infection in vitro 总被引:32,自引:0,他引:32
We have examined the effect of reovirus infection on the CV-1 cytoskeleton. Reovirus infection produces a major disruption of vimentin filaments without producing a discernable disorganization of microtubules or microfilament bundles in CV-1 cells. In addition to disrupting the organization of vimentin filaments, reovirus infection appears to cause a reorganization of vimentin filaments. Viral inclusions contain vimentin filamentous structures. Viral infection also alters the cytoplasmic distribution of mitochondria, consistent with the proposed role of vimentin filaments in determining the distribution of mitochondria. 相似文献

One hundred seven men with Haemophilus ducreyi-positive chancroid were assigned to receive 300 mg of rosoxacin as a single dose or 150 mg twice daily for 3 days. Ulcers and buboes were followed clinically and bacteriologically for 1 month. Of 40 evaluable males on the 3-day regimen, 38 (95%) were cured, while only 14 of 23 (61%) males on the single-dose regimen were cured; this regimen was discontinued. There was one ulcer relapse at day 21 in both groups; the one relapse in the single-dose group had a persistent culture-positive bubo. Eight of nine (89%) buboes followed to the endpoint on the 3-day rosoxacin regimen were cured, versus three of six (50%) on the single-dose regimen. Adverse effects were mainly related to the central nervous system but were minor and did not require intervention. None of the treatment failures was due to organisms resistant to rosoxacin, and failure of the single-dose regimen presumably was related to duration of tissue levels rather than to drug resistance. Administration of 150 mg of rosoxacin twice daily for 3 days is an effective regimen for the therapy of chancroid and is a reasonable alternative to other short-course regimens. 相似文献

The tibial nerve (TN) has three main terminal branches: the medial and lateral plantar nerves and the calcaneal branch (CB), which innervates the foot sole. The design and implantation of nerve cuff electrodes with separate channels for each of these three terminal branches would provide significant sensory information, which can be used in functional electrical stimulation systems to assist standing or to correct foot drop. Detailed quantitative anatomical data about fascicular size and separability of the terminal branches of TN are needed for the design and implantation of such cuff electrodes. Therefore, the branching pattern, the fascicular separability and the fascicular size of the TN posterior to the medial malleolar-calcaneal axis were examined in this study, using ten human TN specimens. The TN branching patterns were highly dispersed. For the CBs, multiple branches were identified in five (50%) of the specimens. For the TN, the bifurcation point was located within the tarsal tunnel in eight (80%) of the cases. The distance proximal to the medial malleolar-calcaneal axis for which the TN could be split ranged form 0 to 41 mm. Quantitative and qualitative data were obtained for the fascicular size and separability of the TN. Only the CB of the TN proved separable for a sufficient length for nerve cuff electrode implantation. The results suggest the use of a two-channel cuff with one common channel for the lateral and medial plantar nerves, having multiple electrodes for selective recording, and one channel for the CB. 相似文献

The purpose of this work was to investigate the performance of the modified BIR‐4 T2 preparation for T2 mapping and propose a method to remove T2 quantification errors in the presence of large B1 and B0 offsets. The theoretical investigation of the magnetization evolution during the T2 preparation in the presence of B1 and B0 offsets showed deviations from a mono‐exponential T2 decay (two parameter fit). A three parameter fit was used to improve T2 accuracy. Furthermore, a two parameter fit with an additional saturation preparation scan was proposed to improve T2 accuracy and precision. These three fitting methods were compared based on simulations, phantom measurements and an in vivo healthy volunteer study of the neck musculature using a 3D TSE readout. The results based upon the pure two parameter fit overestimated T2 in regions with high B0 offsets (up to 40% in phantoms). The three parameter fit T2 values were robust to B0 offsets but with higher standard deviation (up to 40% in simulations). The two parameter fit with the saturation preparation yielded high robustness towards B0 offsets with a noise performance comparable to that of the two parameter fit. In the volunteer study the T2 values obtained by the pure two parameter fit showed a dependence on the field inhomogeneities, whereas the T2 values from the proposed fitting approach were shown to be insensitive to B0 offsets. The proposed method enabled accurate and precise T2 mapping in the presence of large B1 and B0 offsets. 相似文献
