Abstract

Spinel oxides are promising for high-potential cathode materials of photo-rechargeable batteries. However, LiMn1.5M0.5O4 (M = Mn) shows a rapid degradation during charge/discharge under the illumination of UV-visible light. Here, we investigate various spinel-oxide materials by modifying the composition (M = Fe, Co, Ni, Zn) to demonstrate photocharging in a water-in-salt aqueous electrolyte. LiMn1.5Fe0.5O4 exhibited a substantially higher discharge capacity compared to that of LiMn2O4 after long-term photocharging owing to enhanced stability under illumination. This work provides fundamental design guidelines of spinel-oxide cathode materials for the development of photo-rechargeable batteries. [ABSTRACT FROM AUTHOR]

Abstract

© 2020 Elsevier B.V. Electrochemical Stern layers are observed on the surfaces of RuO2 single crystals in 0.1 M CsF electrolyte. The Stern layers formed at the interfaces of RuO2 (110) and (100) are compared to the previously reported Stern layer on Pt(111) [Liu et al., J. Phys. Chem. Lett., 9 (2018) 1265]. While the Cs+ density profiles at the potentials close to hydrogen evolution reactions are similar, the hydration layers intervening the surface and the Cs+ layer are significantly denser on RuO2 surfaces than that on Pt(111) surface, reflecting the oxygen termination of RuO2 surfaces. The overall similarities between Stern layers on ruthenium surfaces and platinum surface suggest the universal presence of Stern layers in all well-defined solid-electrolyte interfaces.

Abstract

Background : Cigarette smoking causes persistent airway inflammation and is considered to be the major cause of chronic obstructive pulmonary disease (COPD). The activation of phosphoinositide 3-kinase (PI3K)/serine-threonine protein kinase (Akt) pathway is known to have an important role in COPD pathogenesis. Phosphatase and tensin homolog deleted from chromosome 10 (PTEN) is a negative regulator of the PI3K/Akt pathway and is the gene most significantly associated with COPD. However, the role of PTEN in COPD pathogenesis remains unclear. / Methods : Bronchial epithelial cells were obtained by bronchial brushing technique from patients with COPD, healthy smokers, and healthy non-smokers....

Abstract

Background : Chronic obstructive pulmonary disease (COPD) has significant extrapulmonary effects including weight loss, nutritional abnormalities, and skeletal muscle dysfunction. Sarcopenia is one of several comorbidities experienced by COPD patients, which may negatively affect quality of life and increase mortality. Previous studies have reported that exercise may reduce the severity of sarcopenia; however, the mechanism is only partially understood. We hypothesized that levels of irisin and myostatin, one of the myokines, are correlated with sarcopenia in COPD patients. / Methods : A total of 39 male COPD patients were enrolled, in addition to 30 male never-smokers as a control group. Pulmonary function testing was performed on all participants, while body-composition analysis was performed on the COPD patients to measure muscle mass and diagnose sarcopenia....

This study was designed to stratify MPM prognosis by using a simple model. Methods Patients diagnosed with MPM in the past 10 years (n = 122) were examined retrospectively. Data on the presence of chest pain, performance status (PS), asbestos exposure, smoking status, white blood cell count (WBC), haemoglobin (Hb) concentration, platelet count (PLT), lactate dehydronate (LD), histology, stage, and date of death or censored status were collected. After the factors were examined in the univariate analysis, recursive partitioning analysis was performed. Results Statistically significant factors related to survival were the type of histology, stage, PS, WBC, PLT, Hb concentration, and LD. Histology, stage, PS, and Hb concentration were used in multivariate analysis. Stage and Hb concentration showed good statistical significance, whereas PS was borderline significant. The survival analyses were stratified into five groups by PS, stage, Hb concentration, and chest pain using recursive partitioning analysis. Group A comprised patients showing the most favourable prognoses (PS 0-2 and Hb concentration >12.1 g dL.sup.-1 or PS 0-2 and Hb concentration [less than or equal to]12.1 g dL.sup.-1 without pain), and group B comprised the remaining patients. The median overall survival in groups A and B was 563 days (95 % confidence interval [CI] 502-779) and 157 days (95 % CI 115-224), respectively (hazard ratio of 5.44 [3.46-8.53, P < 0.0001]). Conclusions The MPM patients with PS 0-2 and Hb concentration >12.1 or [less than or equal to]12.1 g dL.sup.-1 without chest pain had favourable prognoses.
