Plane-Stress Deformation Behavior of CoCrFeMnNi High-Entropy Alloy Sheet under Low Temperatures.

High-entropy alloys are promising candidates expected to be applied in transportation equipment serving in extreme environments due to their excellent properties. CoCrFeMnNi high-entropy alloy is a typical representative of them, and its low temperature performance is excellent. In this study, to evaluate the feasibility of forming HEA shells, the deformation behavior of CoCrFeMnNi under a plane-stress state at lower temperatures was thoroughly studied.

Association of cardiovascular health and periodontitis: a population-based study.

Background: There is a strong association between cardiovascular disease (CVD) and periodontitis. This study utilized the Life Essentials 8 (LE8) score, a composite measure of cardiovascular health (CVH), to elucidate the relationship between CVH and periodontitis.

Methods: Data from 8,649 nationally representative participants in the National Health and Nutrition Examination Survey (NHANES) were analyzed.

The association between oxidative balance score and periodontitis in adults: a population-based study.

Introduction: The pathogenesis between oxidative stress and periodontitis was correlated. The Oxidative Balance Score (OBS) is a systematic tool to assess the effects of diet and lifestyle in relation to oxidative stress. However, the association between OBS and periodontitis has not been reported previously.

Immunoglobulin G4-related disease in the sigmoid colon in patient with severe colonic fibrosis and obstruction: A case report.

Background: Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated condition characterized by abundant IgG4 positive plasma cells and fibrosis in the affected tissues. It affects most parts of the body; however, there are not many reports on IgG4-RD involving the colon.

Case Summary: A 50-year-old man complaining of intermittent fever for more than two years was referred to our hospital.

Restoration of psychosocial functioning in remitted major depressive disorder patients: A 1-year longitudinal study.

Background: The recovery of psychosocial functioning is an important treatment goal for patients with depression. The aim of the present study is to investigate psychosocial functioning restoration 1 year after major depressive disorder (MDD) remission.

Methods: Depression symptoms and psychosocial functioning were assessed in 167 remitted MDD patients at baseline, as well as 1, 2, 6, 9, and 12 months following remission, according to the Hamilton Depression Scale (HAMD-17) and Generic Quality of Life Inventory (GQOLI-74).

Role stress, social support and occupational burnout among physicians in China: a path analysis approach.

Background: Occupational burnout in physicians is prevalent and can have many negative effects. The purposes of this study were to explore the prevalence of occupational burnout and to analyze the effects of social support and role stress on occupational burnout among Chinese physicians.

Methods: Using multistage-stratified cluster random sampling, physicians were selected to participate in the study and completed three questionnaires: the Chinese Maslach Burnout Inventory; the Cross-Cultural Role Conflict, Ambiguity and Overload Scale; and the Social Support Rating Scale.

Deformation Behavior and Microstructural Evolution during Hot Stamping of TA15 Sheets: Experimentation and Modelling.

Near- α titanium alloys have extensive applications in high temperature structural components of aircrafts. To manufacture complex-shaped titanium alloy panel parts with desired microstructure and good properties, an innovative low-cost hot stamping process for titanium alloy was studied in this paper. Firstly, a series of hot tensile tests and Scanning Electron Microscope (SEM) observations were performed to investigate hot deformation characteristics and identify typical microstructural evolutions.

Work-family conflict and job burn-out among Chinese doctors: the mediating role of coping styles.

Background: Burn-out among doctors threatens their own health, and that of their patients. To identify risk factors of the doctor burn-out is vital to improving their health and increasing the quality of healthcare services. This study aims to explore the relationship between work-family conflict (WFC) and burn-out among Chinese doctors and the mediating role of coping styles in this relationship.

Synthesis and Fluorescent Property Study of Novel 1,8-Naphthalimide-Based Chemosensors.

A series of novel mono- and di-substituted -n-butyl-1,8-naphthalimide derivatives were synthesized simultaneously via a three-step reaction. The single crystal structure of -n-butyl-4-[','-bis(2',4'-dichlorobenzoyl)ethylamino]-1,8-naphthalimide () was determined. The UV-vis and fluorescence properties of compound were investigated.

Shortening distance of forward and reverse primers for nucleic acid isothermal amplification.

Existent nucleic acid isothermal detection techniques for clinical diseases are difficult to promote greatly due to limitations in such aspects as methodology, costs of detection, amplification efficiency and conditions for operation. There is therefore an urgent need for a new isothermal amplification method with the characteristics of high accuracy, easy operation, short time of detection and low costs. We have devised a new method of nucleic acid isothermal amplification using Bst DNA polymerase under isothermal conditions (60-65°C).

Preparation and chiral recognition in HPLC of cellulose 3,5-dichlorophenylcarbamates immobilized onto silica gel.

The 3,5-dichlorophenylcarbamates (2) of cellulose bearing a small amount of 3-(triethoxysilyl)propyl residues were synthesized by a one-pot process and immobilized onto a silica gel through intermolecular polycondensation of the triethoxysilyl groups. The obtained cellulose derivatives were characterized by (1) H NMR and elemental analysis (EA), and their recognition abilities were evaluated by high-performance liquid chromatography (HPLC). The cellulose derivatives containing about 1-5% of the 3-(triethoxysilyl)propyl residue were efficiently immobilized with a high chiral recognition ability.
