Positive association between patient experience of primary care with chronic disease and self-rated health in a Japanese rural area: A cross-sectional questionnaire survey using the Japanese primary care assessment tool short form.

Background: Low birthrates and an aging society during population decline have brought about labor shortages and increased medical care needs. Medical resources should be distributed appropriately, particularly in rural areas. High-quality primary care can make the medical system more effective and contribute to rural residents' health.

Fluorous and Organic Extraction Systems: A Comparison from the Perspectives of Coordination Structures, Interfaces, and Bulk Extraction Phases.

Microscopic structures in liquid-liquid extraction, such as structuration between extractants or extracted complexes in bulk organic phases and at interfaces, can influence macroscopic phenomena, such as the distribution behavior of solutes, including extraction efficiency and selectivity. In this study, we correlated the macroscopic behavior of the Zr(IV) extraction from nitric acid solutions with microscopic structural information to understand at the molecular level the key factors contributing to the higher metal ion extraction performance in the fluorous extraction system as compared to the analogous organic extraction system. The fluorous and organic extraction systems consist of tris(4,4,5,5,6,6,7,7,7-nonafluoroheptyl) phosphate (TFP) in perfluorohexane and tri--heptyl phosphate (THP) in -hexane, respectively.

Spatiotemporal evolution of molar fraction in acoustic-resonance tube filled with He-Ar mixture.

This study proposes a time-evolution method to simulate acoustic gas-mixture separation. The proposed method can calculate the separation process without any arbitrary parameters except for space and time resolutions. The molar-fraction distribution within the system during the separation can be calculated, and the results show that a large molar-fraction gradient occurs in the separation tube, while a distribution also occurs in the resonance tube.

Fatty acid metabolism constrains Th9 cell differentiation and antitumor immunity via the modulation of retinoic acid receptor signaling.

T helper 9 (Th9) cells are interleukin 9 (IL-9)-producing cells that have diverse functions ranging from antitumor immune responses to allergic inflammation. Th9 cells differentiate from naïve CD4 T cells in the presence of IL-4 and transforming growth factor-beta (TGF-β); however, our understanding of the molecular basis of their differentiation remains incomplete. Previously, we reported that the differentiation of another subset of TGF-β-driven T helper cells, Th17 cells, is highly dependent on de novo lipid biosynthesis.

Developing an RNA Signature for Radiation Injury Using a Human Liver-on-a-Chip Model.

Radiation exposure in a therapeutic setting or during a mass casualty event requires improved medical triaging, where the time to delivery and quantity of medical countermeasures are critical to survival. Radiation-induced liver injury (RILI) and fibrosis can lead to death, but clinical symptoms manifest late in disease pathogenesis and there is no simple diagnostic test to determine RILI. Because animal models do not completely recapitulate clinical symptoms, we used a human liver-on-a-chip model to identify biomarkers of RILI.

Current Status of Conversion Hepatectomy After Sorafenib and Lenvatinib Treatment for Unresectable Hepatocellular Carcinoma.

Background/aim: Sorafenib and lenvatinib have long been used as a first-line treatment for advanced hepatocellular carcinoma (HCC). Along with the development of systemic chemotherapy for HCC, the concept of conversion hepatectomy has recently become widespread. The present study aimed to assess the clinical outcomes of sorafenib and lenvatinib for HCC regarding the possibility of conversion hepatectomy in clinical practice.

Globular pattern formation of hierarchical ceria nanoarchitectures.

Dissipative structures often appear as an unstable counterpart of ordered structures owing to fluctuations that do not form a homogeneous phase. Even a multiphase mixture may simultaneously undergo one chemical reaction near equilibrium and another one that is far from equilibrium. Here, we observed in real time crystal seed formation and simultaneous nanocrystal aggregation proceeding from Ce complexes to CeO nanoparticles in an acidic aqueous solution, and investigated the resultant hierarchical nanoarchitecture.

A homeostatic role of nucleus-actin filament coupling in the regulation of cellular traction forces in fibroblasts.

Cellular traction forces are contractile forces that depend on the material/substrate stiffness and play essential roles in sensing mechanical environments and regulating cell morphology and function. Traction forces are primarily generated by the actin cytoskeleton and transmitted to the substrate through focal adhesions. The cell nucleus is also believed to be involved in the regulation of this type of force; however, the role of the nucleus in cellular traction forces remains unclear.

Revisiting acoustical gas-mixture separation.

This study experimentally investigated acoustically driven gas-mixture separation. Acoustic wave propagation in a narrow tube can induce gas-mixture separation. A binary mixture of helium and argon was used as the gas mixture.

Nusinersen induces detectable changes in compound motor action potential response in spinal muscular atrophy type 1 patients with severe impairment of motor function.

Background: Most long-term affected spinal muscular atrophy (SMA) type 1 patients have severe impairment of motor function and are dependent on mechanical ventilation with tracheostomy. The efficacy and safety of nusinersen in these patients have not been established.

Methods: We retrospectively evaluated the efficacy of intrathecal nusinersen treatment in patients with SMA type 1 who continued treatment for at least 12 months.

Use of lacosamide for focal epilepsy in a child with kidney failure undergoing peritoneal dialysis.

Background: Lacosamide (LCM) has become commonly used for focal onset seizures due to its high tolerability and low drug interactions. Unlike patients on hemodialysis (HD), pharmacokinetic data and dosing recommendations for patients undergoing peritoneal dialysis (PD) are scant.

Case Report: A 2-year-old girl with end-stage kidney disease undergoing PD suffered prolonged focal onset seizures.

Therapeutic effects of KRM-II-81, positive allosteric modulator for α2/3 subunit containing GABA receptors, in a mouse model of Dravet syndrome.

Dravet syndrome (DS) is an intractable epilepsy syndrome concomitant with neurodevelopmental disorder that begins in infancy. DS is dominantly caused by mutations in the gene, which encodes the α subunit of a voltage-gated Na channel. Pre-synaptic inhibitory dysfunction is regarded as the pathophysiological mechanism, but an effective strategy for ameliorating seizures and behavioral problems is still under development.

Foam Flotation of Clay Particles Using a Bifunctional Amine Surfactant.

Understanding clay flotation mechanisms has become a major concern because of the increasing level of environmental contamination of soil and ground water by heavy metals and radionuclides. Clays are often used as sorbents for extracting metals in indirect flotation processes but can function simultaneously as defoamers. However, how foam generation and stability depend on the molecular interactions between the clays and surfactant is still controversial.

Biomarkers for Biodosimetry and Their Role in Predicting Radiation Injury.

Radiation-related normal tissue injury sustained during cancer radiotherapy or in a radiological or mass casualty nuclear incident is a major health concern. Reducing the risk and mitigating consequences of radiation injury could have a broad impact on cancer patients and citizens. Efforts to discover biomarkers that can determine radiation dose, predict tissue damage, and aid medical triage are underway.

Negative association between loneliness and healthy state among rural residents in Japan: a cross-sectional single region population-based survey.

Loneliness is an important health problem in rural areas of Japan because of its ageing and declining population. Therefore, we investigated the association between loneliness and health. Self-administered questionnaires were distributed to rural adult residents.

Hierarchical Aggregation in a Complex Fluid─The Role of Isomeric Interconversion.

There is an ever-increasing body of evidence that metallic complexes involving amphiliphic ligands do not form normal solutions in organic solvents. Instead, they form complex fluids with intricate structures. For example, the metallic complexes may aggregate into clusters, and these clusters themselves may aggregate into superclusters.
