Highly-efficient full-color holographic movie based on silicon nitride metasurface.

Metasurface holograms offer various advantages, including wide viewing angle, small volume, and high resolution. However, full-color animation of high-resolution images has been a challenging issue. In this study, a full-color dielectric metasurface holographic movie with a resolution of 2322 × 2322 was achieved by spatiotemporally multiplexing 30 frames with blue, green, and red color channels at the wavelengths of 445 nm, 532 nm, and 633 nm at the maximum reconstruction speed of 55.

Surgical outcome in patients with lung adenocarcinoma with mucin.

Objective: Mucin-producing adenocarcinoma is a less common variant of lung adenocarcinoma. Adenocarcinoma cells with mucin can spread through the airspace via mucus-mediated extension, leading to their implantation in distant normal lungs. Consequently, post-operative intrapulmonary recurrence frequently occurs.

Use of an eligibility checklist on arrival of emergency room as a registry system for corneal donation-A 9-year retrospective cohort study.

Aim: This study aimed to evaluate whether the use of an eligibility checklist uncovered potential corneal donors among deceased outpatients and increased the donation.

Association between Poor Outcomes and Risk of Refeeding Syndrome among Patients Urgently Admitted to the High Dependency Unit: A Single-Center Cohort Study in Japan.

Refeeding syndrome (RFS) is recognized as a potentially fatal metabolic disturbance, particularly concerning for non-critically ill patients who do not receive frequent electrolyte assessments. Assessing the risk of developing RFS and implementing preventive strategies is essential in these cases. We investigated the proportion of risk and its association with prognosis in a high-dependency unit (HDU).

Urgent Contrast-Enhanced Computed Tomography before Early Colonoscopy in the Management of Colonic Diverticular Bleeding: A Multicenter Randomized Controlled Trial.

Introduction: Contrast-enhanced computed tomography (CE-CT) has been gaining attention as an initial investigation in the management of colonic diverticular bleeding (CDB), yet the role of CE-CT other than its diagnostic yield has not been adequately clarified. We aimed to determine whether the use of urgent CE-CT improves identification of stigmata of recent hemorrhage (SRH) in subsequently performed early colonoscopy (≤24 h of arrival) or other clinical outcomes of CDB.

Methods: We conducted a randomized, open-label, controlled trial at 23 institutions in Japan.

Immunohistochemical distribution of cannabinoid receptor type 1 (CB1) and type 2 (CB2) in the rat carotid body.

The carotid body is a hypoxia-sensitive chemoreceptor that induces sensory long-term facilitation after exposure to chronic intermittent hypoxia. However, the mechanisms underlying synaptic plasticity in the carotid body remain unknown. In the present study, we examined the immunohistochemical distribution of cannabinoid receptor type 1 (CB1) and type 2 (CB2), which are candidate molecules involved in the modulation of synaptic transmission.

Increasing monocytes after lung cancer surgery triggers the outgrowth of distant metastases, causing recurrence.

Patients with lung cancer have a high incidence of tumor recurrence even after curative surgical resection. Some reports indicated that immunosuppressive cells induced by surgical stress could contribute to tumor recurrence after surgery; however, the underlying mechanisms are not fully understood. In this study, we found that increased postoperative blood monocytes served as a risk factor for tumor recurrence in 192 patients with non-small cell lung cancer (NSCLC).

Characterization of quantitative trait loci from DJ123 () independently affecting panicle structure traits in rice cultivar IR64.

Unlabelled: The rice panicle is the principal organ to influence productivity and traits affecting panicle architecture determine sink size and yield potential. Improving panicle architecture may be effective in increasing yield under low-input conditions, but which traits are of importance under such conditions and how they are genetically controlled is not well understood. Using recombinant inbred lines (RILs) derived from a cross between a modern variety IR64 and a low fertility tolerant accession DJ123, quantitative trait locus (QTL) mapping was conducted under high soil fertility in Japan and low fertility in Madagascar.

A higher area under the concentration-time curve/minimum inhibitory concentration target as a potential prognostic factor for vancomycin treatment of methicillin-resistant meningitis: A case report.

Is the increase in the number of total hip arthroplasties in Japan due to an aging society?

Background: The number of total hip arthroplasty (THA) is increasing globally, including Japan. The Japanese Orthopaedic Association has been conducting a registry of joint replacement surgery, but there may be a gap between the reported numbers of THA in the registry and the actual number. This study aimed to investigate the exact number of THA and assess the trends in Japan using the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB).

Engineering Mixing Properties of Fluids by Spatial Modulations.

We propose a method to change the effective interaction between two fluids by modulation of their local density distributions with external periodic potentials, whereby the mixing properties can be controlled. This method is applied to a mixture of dilute bosonic gases, and binodal and spinodal curves emerge in the phase diagram. Spinodal decomposition into a mixed-bubble state becomes possible, in which one of the coexisting phases has a finite mixing ratio.
