PhysiCan - a device for automatic CPM exercises implementation over canines: Design and analysis.

Continuous Passive Motion (CPM) devices have been used to assist physicians conducting human rehabilitation; however, similar machines specific for canine rehabilitation have not been found in the reviewed literature. This research performed a physical analysis of the hind limb of dogs to design a device for implementing automated CPM exercises. The device proved to comply with the guidelines to perform CPM exercises, allowing a proper setting of parameters to generate rehabilitation routines customized for different rehabilitation requirements.

Oxygen vacancies in Ru/TiO - drivers of low-temperature CO methanation assessed by multimodal operando spectroscopy.

Hydrogenation of CO is very attractive for transforming this greenhouse gas into valuable high energy density compounds. In this work, we developed a highly active and stable Ru/TiO catalyst for CO methanation prepared by a solgel method that revealed much higher activity in methanation of CO (ca. 4-14 times higher turnover frequencies at 140-210°C) than state-of-the-art Ru/TiO catalysts and a control sample prepared by wetness impregnation.

Morphology-Engineered Highly Active and Stable Ru/TiO Catalysts for Selective CO Methanation.

Ru/TiO catalysts exhibit an exceptionally high activity in the selective methanation of CO in CO - and H -rich reformates, but suffer from continuous deactivation during reaction. This limitation can be overcome through the fabrication of highly active and non-deactivating Ru/TiO catalysts by engineering the morphology of the TiO support. Using anatase TiO nanocrystals with mainly {001}, {100}, or {101} facets exposed, we show that after an initial activation period Ru/TiO -{100} and Ru/TiO -{101} are very stable, while Ru/TiO -{001} deactivates continuously.

An unusual neck tumor in a young pregnant woman: challenge diagnosis and response to treatment.

We report the case of a 19-year-old woman 33 weeks pregnant who presented a painful mass of progressive growth in the neck, having also dysphonia and dyspnea. Physical examination revealed a primary laryngeal tumor. A neuroendocrine small-cell carcinoma was diagnosed after histopathology, immunohistochemistry and genetic studies.
