WSC-Trans: A 3D network model for automatic multi-structural segmentation of temporal bone CT [PDF]

arXiv, 2022
Cochlear implantation is currently the most effective treatment for patients with severe deafness, but mastering cochlear implantation is extremely challenging because the temporal bone has extremely complex and small three-dimensional anatomical structures, and it is important to avoid damaging the corresponding structures when performing surgery.

Ototoxicidade por organofosforados: descrição dos aspectos ultraestruturais do sistema vestibulococlear de cobaias Organophosphate-related ototoxicity: Description of the vestibulocochlear system ultrastructural aspects of guinea pigs

Brazilian Journal of Otorhinolaryngology, 2010
Os agrotóxicos organofosforados são amplamente utilizados na agricultura, e atualmente fazem parte do grupo de agentes químicos que podem levar à perda auditiva, no qual já estavam incluídos os solventes, os metais e os asfixiantes.

Neuroimaging for differential diagnosis of transient neurological attacks

Brain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Background Rapid yet comprehensive neuroimaging protocols are required for patients with suspected acute stroke. However, stroke mimics can account for approximately one in five clinically diagnosed acute ischemic strokes and the rate of thrombolyzed mimics can be as high as 17%.

Mechanosensitive Channel Activation by Diffusio-Osmotic Force [PDF]

, 2014
For ion channel gating, the appearance of two distinct conformational states and the discrete transitions between them is essential, and therefore of crucial importance to all living organisms. We show that the physical interplay between two structural elements that are commonly present in bacterial mechanosensitive channels, namely a charged vestibule

Carcinoma of the nasal vestibule

International Journal of Radiation Oncology*Biology*Physics, 1984
Squamous cell carcinomas of the nasal vestibule are essentially skin cancers that require special therapeutic considerations because of the regional anatomy. They have sometimes been considered poorly suited for treatment by irradiation because of potential or actual cartilage and/or bone invasion and therefore have been treated by surgical resection ...

Simulation‐based team‐training in acute stroke: Is it safe to speed up?

Brain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Background In acute ischemic stroke (AIS), rapid treatment with intravenous thrombolysis (IVT) is crucial for good clinical outcome. Weekly simulation‐based team‐training of the stroke treatment team was implemented, resulting in faster treatment times.

Simulation of gating currents of the Shaker K channel using a Brownian model of the voltage sensor [PDF]

, 2018
The physical mechanism underlying the voltage-dependent gating of K channels is usually addressed theoretically using molecular dynamics simulations.However, besides being computationally very expensive, this approach is presently unable to fully predict the behavior of fundamental variables of channel gating, such as the macroscopic gating current.To ...

Sustainable entrepreneurship and legitimacy building in protected areas: Overcoming distinctive barriers through activism

Business Strategy and the Environment, Volume 32, Issue 1, Page 72-95, January 2023., 2023
Abstract Sustainable entrepreneurs operating in protected areas face distinctive barriers that place additional emphasis on the need to build legitimacy. To date, how they do this has not been entirely explored. This paper addresses this need through an exploratory study of sustainable entrepreneurs in a transnational protected area.

Reconstruction of lingual sulcus in a severely atrophic mandible using a modified approach as a pre‐prosthetic surgery: Case series

Clinical Case Reports, 2022
Shallow lingual vestibule and lack of keratinized attached mucosa are considered risk factors for the long‐term success of dental implants. This article describes a modified surgical approach accompanied by a free gingival graft to correct the shallow ...
