[Implantation of complex tissue flap for atrophic rhinitis].

OBJECTIVE: To improve the treatment effect of atrophic rhinitis. METHOD: Twenty-one cases (thirty-one sides) of atrophic rhinitis were treated by implantation of complex tissue flap to narrow the nasal cavity. RESULT: Short-term effective treatment results were 100% (21/21), long-term effective treatment results were 90.5% (19/21). CONCLUSION: Implantation of complex tissue flap offers a simple and effective way and can be recommended for the treatment of atrophic rhinitis.

Web-based Simulation for Contrast Transfer Function and Envelope Functions.

We have implemented a Web-based simulation program for the contrast transfer function and envelope functions in Java and JavaScript. The simulation provides interactive controls of all the parameters in those functions. In addition to the predefined functions, users can easily define new functions that use any of the parameters in the preset functions. The most useful feature of this new simulation program is the convenient, universal accessibility through Web browsers on any computer platform that supports Java, such as Netscape and Internet Explorer.

Applications of a bilateral denoising filter in biological electron microscopy.

Due to the sensitivity of biological sample to the radiation damage, the low dose imaging conditions used for electron microscopy result in extremely noisy images. The processes of digitization, image alignment, and 3D reconstruction also introduce additional sources of noise in the final 3D structure. In this paper, we investigate the effectiveness of a bilateral denoising filter in various biological electron microscopy applications. In contrast to the conventional low pass filters, which inevitably smooth out both noise and structural features simultaneously, we found that bilateral filter holds a distinct advantage in being capable of effectively suppressing noise without blurring the high resolution details. In as much, we have applied this technique to individual micrographs, entire 3D reconstructions, segmented proteins, and tomographic reconstructions.
