RDMAS: a web server for RNA deleterious mutation analysis.

BACKGROUND: The diverse functions of ncRNAs critically depend on their structures. Mutations in ncRNAs disrupting the structures of functional sites are expected to be deleterious. RNA deleterious mutations have attracted wide attentions because some of them in cells result in serious disease, and some others in microbes influence their fitness. RESULTS: The RDMAS web server we describe here is an online tool for evaluating structural deleteriousness of single nucleotide mutation in RNA genes. Several structure comparison methods have been integrated; sub-optimal structures predicted can be optionally involved to mitigate the uncertainty of secondary structure prediction. With a user-friendly interface, the web application is easy to use. Intuitive illustrations are provided along with the original computational results to facilitate quick analysis. CONCLUSION: RDMAS can be used to explore the structure alterations which cause mutations pathogenic, and to predict deleterious mutations which may help to determine the functionally critical regions. RDMAS is freely accessed via http://biosrv1.bmi.ac.cn/rdmas.

Free flap transfer bridged by antegrade and retrograde posterior tibial vessel flaps temporally borrowed from the healthy leg.

OBJECTIVE: To study the methods and techniques of free flap transfer bridged by posterior tibial vascular flap in treating large soft tissue defects in low limbs without usable recipient blood vessels. METHODS: Based on morphological observation and measurement of arterial pressure and blood flow, an antegrade and a retrograde vascular bridge flaps were designed using the healthy posterior tibial vessels to serve as vascular pedicles to carry two free flaps for transplantation. RESULTS: Eight cases of patient with one or two large soft tissue defects in the leg region were treated by the method. All the bridge flaps and free flaps survived well, and the defects were repaired completely. CONCLUSIONS: The results showed that it is an ideal method for using the posterior tibial vessels from the healthy limb to form vascular pedicles in repairing large soft tissue defects in patients without a usable recipient blood vessel.
