Interleukin-34-NF-κB signaling aggravates myocardial ischemic/reperfusion injury by facilitating macrophage recruitment and polarization.

Background: Macrophage infiltration and polarization are integral to the progression of heart failure and cardiac fibrosis after ischemia/reperfusion (IR). Interleukin 34 (IL-34) is an inflammatory regulator related to a series of autoimmune diseases. Whether IL-34 mediates inflammatory responses and contributes to cardiac remodeling and heart failure post-IR remains unclear.

Review on Progress of Lamellar Orientation Control in Directionally Solidified TiAl Alloys.

TiAl alloys have excellent high-temperature performance and are potentially used in the aerospace industry. By controlling the lamellar orientation through directional solidification (DS) technology, the plasticity and strength of TiAl alloy at room temperature and high temperatures can be effectively improved. However, various difficulties lie in ensuring the lamellar orientation is parallel to the growth direction.

Crystal Structure and Bond-Valence Investigation of Nitrogen-Stabilized LiAlO Spinels.

An in-depth insight into the effect of nitrogen substitution on structural stabilization is important for the design of new spinel-type oxynitride materials with tailored properties. In this work, the crystal structures of ordered and disordered LiAlO obtained by slow cooling and rapid quenching, respectively, were analyzed by a X-ray diffraction (XRD) Rietveld refinement and OccQP program. The variation in the bonding state of atoms in the two compounds was explored by the bond valence model, which revealed that the instability of spinel-type LiAlO crystal structure at room temperature is mainly due to the severe under-bonding of the tetrahedrally coordinated Al cations.

Trimethyllysine, a trimethylamine N-oxide precursor, predicts the presence, severity, and prognosis of heart failure.

Methods And Results: Totally 956 subjects were enrolled consecutively from the Department of Cardiovascular Medicine, Ruijin Hospital. Baseline data were obtained from all participants, and 471 stable chronic HF subjects were followed up.

Femtosecond Laser for Cavity Preparation in Enamel and Dentin: Axial Wall Taper Related Factors.

Femtosecond laser (fs-laser) is a novel tooth preparation tool. After cavities were prepared by fs-laser, their axial-wall taper is closely related to the retention force and success of restorations, while the taper after preparation by fs-laser is not clear yet. This study aimed to explore the value of the taper after fs-laser tooth preparation and the effect of laser fluence, scanning line spacing, and scanning layers on taper.

Herein, a feasible strategy based on a femtosecond laser (fs-laser) was provided to decelerate dentin wear, and the effect of wear resistance improvement and its potential mechanism were explored. Tooth wear is a common phenomenon that exists throughout life. While once dentin is exposed, it wears away very quickly.

Expression of miR-210, miR-137, and miR-153 in Patients with Acute Cerebral Infarction.

Aim: To explore the expression levels of miR-210, miR-137, and miR-153 in patients with acute cerebral infarction. . 76 patients with acute cerebral infarction treated in our hospital from April 2016 to October 2017 were enrolled as the observation group.

High Proteoglycan Decorin Levels Are Associated With Acute Coronary Syndrome and Provoke an Imbalanced Inflammatory Response.

Acute coronary syndrome (ACS) has become one of the most common causes of disability. It is thus important to identify ACS early in the disease course of patients using novel biomarkers for prompt management. Decorin (DCN) was well-acknowledged for its effect on collagen fibrillogenesis and maintaining tissue integrity.

The positive effects of inoculation using arbuscular mycorrhizal fungi and/or dark septate endophytes on the purification efficiency of CuO-nanoparticles-polluted wastewater in constructed wetland.

The extent to which, and mechanisms by which, arbuscular mycorrhizal fungi (AMF) and dark septate endophytes (DSE) purify wetlands polluted by metallic nanoparticles (metallic NPs) are not well understood. In this study, micro-vertical flow constructed wetlands (MVFCWs) with the Phragmites australis (reeds)-AMF/DSE symbiont were used to treat CuO nanoparticles (CuO-NPs)-polluted wastewater. The results showed that (1) the removal efficiencies of chemical oxygen demand (COD), total nitrogen (TN), and CuO-NPs in three inoculated groups significantly exceeded those in the control check (CK) groups by 28.

Progress in Research of Asymptomatic Primary Mitral Regurgitation Examination Methods: A Review of Literature.

Mitral regurgitation (MR) is a common valvular heart disease, which can be classified into primary and secondary, according to the cause. Primary mitral regurgitation (PMR) is caused by rheumatic fever, degenerative changes, valve prolapse, etc. The appearance of clinical symptoms has always been the best indicator of surgical intervention in patients with severe PMR, but for asymptomatic patients, the best treatment has been controversial.

Soluble ST2 levels for predicting the presence and severity of metabolic syndrome.

Structural Study of MgAlON (0 < < 0.5, 0 < < 1) Spinel Probed by X-ray Diffraction, Al MAS NMR, and First-Principles Calculations.

The deep understanding of the crystal structure and composition-structure relationship is important for modifying and designing solids to obtain functional materials with customized properties. However, because of multiple compositions and complex structures in some spinel solid solutions, the composition-structure relationship is unknown, or becomes very complicated and difficult to be controlled. In this work, the solid-state magic-angle spinning nuclear magnetic resonance (MAS NMR) technique and powder X-ray diffraction (XRD) Rietveld refinement were combined to characterize the crystal structure of quaternary disordered MgAlON solid solutions in detail, which was supported by the first-principles density functional theory calculations.

TiO nanoparticles (TiONPs) is one of the most widely used nanomaterials. Arbuscular mycorrhizal fungi (AMF) are an important and widely distributed group of soil microorganisms, which promote the absorption of nutrients by host plants and increase their tolerance to contaminants. However, the effects and mechanisms of AMF on plant TiONPs tolerance in wetland habitats are not clear.

[Water purification of four aquatic plant species with the presence of iron-carbon interior electrolytic substrates.].

To compare water purification of common aquatic plants in wetland ecosystem, four common aquatic plant species (Eichhornia crassipes, Nymphaea tetragona, Acorus calamus and Phragmites australis) were used as study species. The effect of aquatic plants on the change of sewage ammonium nitrogen, COD, TP content during different experimental time (1-5 d) with the presence of iron-carbon interior electrolytic substrates were analyzed in small scale experimental apparatus. The results showed that single and combined aquatic plants could effectively remove ammonium nitrogen, COD, TP from the sewage compared with the no-plant control group, but the efficiencies were significantly different among the different species.
