Effects of Oral Function Training and Oral Health Status on Physical Performance in Potentially Dependent Older Adults.

This study aimed to evaluate the effects of an oral function training program and indicators of oral health status on improvements in physical performance induced by physical function training in dependent older adults. The participants were 131 potentially dependent older adults (age: ≥65 years) who were randomly divided into two groups: an oral intervention and a control group. All participants underwent physical function training, but only the intervention group took part in the oral function training program.

Development and Early Feasibility of Chatbots for Educating Patients With Lung Cancer and Their Caregivers in Japan: Mixed Methods Study.

Background: Chatbots are artificial intelligence-driven programs that interact with people. The applications of this technology include the collection and delivery of information, generation of and responding to inquiries, collection of end user feedback, and the delivery of personalized health and medical information to patients through cellphone- and web-based platforms. However, no chatbots have been developed for patients with lung cancer and their caregivers.

Enhancement of image contrast for carbon nanotube and polymer composite film in scanning electron microscope.

Image contrast between carbon nanotubes (CNTs) and polytetrafluoroethylene (PTFE) in a CNT/PTFE composite film, which is difficult to obtain by conventional backscattered electron (BSE) imaging, was optimized to better elucidate the distribution of CNT in the film. Ultra-low landing energy condition (0.3 keV in this study) was used to prevent specimen damage due to electron beam irradiation.

Correction to: Postmortem computed tomographic features in the diagnosis of drowning: a comparison of fresh water and salt water drowning cases.

Whereas in FWDCs, a significantly larger volume and lower density of fluid in the paranasal sinuses (P = 0.0195 and P = 0.0104, respectively), lower density of fluid in the central airways (P = 0.

Postmortem computed tomographic features in the diagnosis of drowning: a comparison of fresh water and salt water drowning cases.

Purpose: To investigate the effectiveness of postmortem computed tomography in the diagnosis of drowning, focusing on the comparison of fresh water and salt water cases using three-dimensionally (3D) reconstructed data.

Materials And Methods: We examined features of drowning in 25 fresh water drowning cases (FWDCs; 13 men, 12 women; mean age 73.1 years; range 43-95 years), and compared these with 12 salt water drowning cases (SWDCs; 5 men, 7 women; mean age 66.
