Stochastic marine ecosystem modeling for statistical interpretation of the uncertainty factors used for the determination of tolerable daily intake of polychlorinated biphenyls.

This study developed a numerical simulation model for a marine ecosystem to determine accumulation levels of polychlorinated biphenyls (PCBs) in top predators (seabasses). The simulated results were used for calculating probabilities of exceeding tolerable daily intake (TDI) of seafoods enforced by the US and Japanese governments. The model was applied to Tokyo Bay, Japan.

Novel Treatment of 3D-Printed Short-Carbon-Fiber-Reinforced Polyamide (3D-SCFRPA66) Using Homogeneous Low-Potential Electron Beam Irradiation (HLEBI) and Ductility Enhancement.

In short-carbon-fiber-reinforced polyamide 66 articles shaped by 3D printing (3D-SCFRPA66), the interfaces between printed layers are often susceptible to damage, and the composite is excessively brittle. Therefore, a novel treatment for 3D-printed short-carbon-fiber-reinforced polyamide (3D-SCFRPA66) using homogeneous low-potential electron beam irradiation (HLEBI) to enhance tensile properties was investigated. In 3D-SCFRPA66 samples, ductility was measured based on the following parameters: strain at tensile strength (corresponding to homogeneous deformation) () and resistance energy to homogeneous deformation, a measure of toughness (), which were both substantially increased.

The disinfectant effects of portable ultraviolet light devices and their application to dentures.

Interest in ultraviolet (UV) light devices for disinfection has increased due to pandemic concerns, but their efficacy in denture disinfection is underexplored. This study evaluated seven-enclosed type portable UV irradiation devices (devices A-G). Among these, devices A, B, and C used bulb light sources, while devices D, E, F, and G utilized LED (light-emitting diode) light sources.

Case report: A novel transcutaneous electrical nerve stimulation improves dysesthesias and motor behaviors after transverse myelitis.

Purpose: Transverse myelitis (TM)-associated dysesthesia is diverse and frequently resistant to treatment. This study explored the comprehensive effects of a novel transcutaneous electrical nerve stimulation (TENS) approach tailored to an individual's specific dysesthesia profile in a patient with TM.

Patient And Method: A 52-year-old woman with severe dysesthesias in the left C8 sensory area caused by TM underwent an A-B-A-B-A design intervention.

Acute DWI volume is a strong imaging predictor of favorable outcomes in patients with acute stroke and treated with mechanical thrombectomy.

Background: Infarct volume on diffusion-weighted imaging (DWI) is a promising imaging marker for clinical outcomes in patients with acute stroke treated with mechanical thrombectomy (MT), but its predictive value has not been well evaluated, especially in consecutive patients. The present study aimed to elucidate the relationship between infarct volume and its change and favorable functional outcomes in consecutive patients with acute stroke who underwent MT.

Method: Of patients with consecutive acute stroke who underwent MT from September 2014 through December 2019, those who were pre-morbidly independent were enrolled.
