Histologic characterization of orbicularis oris muscle with a new acellular dermal matrix grafts in a rabbit model.

J Tissue Eng Regen Med 2022 May 7. Epub 2022 May 7.

State Key Laboratory of Oral Diseases & National Clinical Research Center for Oral Diseases & Department of Cleft Lip and Palate Surgery, West China School of Stomatology, Sichuan University, Chengdu, China.

Muscular dysplasia is the key factor in influencing surgical outcomes in patients with cleft lip/palate. In this research, we attempted to evaluate a new acellular dermal matrix (ADM) as a substitute for reconstruction of the orbicularis oris muscle with growth factors such as Insulin-Like Growth Factor I (IGF-I), vascular endothelial growth factor (VEGF) in a rabbit model. 30 male New Zealand Rabbits (2-3 m, 1700-2000 g) were divided into four groups as follows; a group in which the orbicularis oris muscle of the upper lip was implanted with ADM, a group in which the orbicularis oris muscle of the upper lip was implanted with ADM + IGF-I + VEGF, a group in which the upper lip was operated without implantation of an ADM scaffold, and a normal upper lip for comparison.

End-to-End Video-to-Speech Synthesis Using Generative Adversarial Networks.

IEEE Trans Cybern 2022 Apr 19;PP. Epub 2022 Apr 19.

Video-to-speech is the process of reconstructing the audio speech from a video of a spoken utterance. Previous approaches to this task have relied on a two-step process where an intermediate representation is inferred from the video and is then decoded into waveform audio using a vocoder or a waveform reconstruction algorithm. In this work, we propose a new end-to-end video-to-speech model based on generative adversarial networks (GANs) which translates spoken video to waveform end-to-end without using any intermediate representation or separate waveform synthesis algorithm.
