Energy-splitting from persistent luminescence nanoparticles with trivalent Cr ions for ratiometric temperature sensing.

MgGaO (MGO) with the spinel structure exhibits abundance defects and could achieve the modulation of emission by ion doping as persistent luminescence nanoparticles (PLNPs). Here, we introduced Cr ions into MGO to achieve near-infrared (NIR) emission, and Pr ions to tune the lattice environment for enhanced NIR emission. The optimal composite, MgGaO: 0.

Comparison of errors in ablation depth calculation after myopic femtosecond laser in situ keratomileusis in patients with different degrees of myopia: a prospective study.

Background: To investigate the difference between the predicted preoperative corneal ablation depth and the measured ablation depth for femtosecond laser in situ keratomileusis (FS-LASIK) in patients with different degrees of myopia, and to analyze the source of the difference.

Methods: A total of 55 patients (109 eyes) were included in this study. Multiple logistics regression was applied to analyze the sources affecting postoperative refractive outcomes.

Glycyrrhizic Acid Protects Glomerular Podocytes Induced by High Glucose by Modulating SNARK/AMPK Signaling Pathway.

Objective: Diabetic nephropathy is one of the most important microvascular complications of diabetes, which mainly refers to glomerular capillary sclerosis. Podocytes are an important part of glomerular capillaries. Previous clinical and basic studies have shown that fibrosis is the main factor of diabetic nephropathy.

[Effects of grazing on soil aggregate composition and stability in desert steppe].

Grazing, one of the main grassland utilization modes, has notable impacts on grassland ecosystem structure and functions. However, the effects of long-term grazing on soil aggregate composition and stability are poorly understood. Based on a long-term grazing experiment platform in Inner Mongolia desert steppe established in 2004, with treatements of no grazing (control), light, moderate, and heavy grazing intensities, we studied the changes of soil aggregate composition and stability under different grazing intensities.

Neutrophil extracellular traps participate in the development of cancer-associated thrombosis in patients with gastric cancer.

Background: The development of venous thromboembolism (VTE) is associated with high mortality among gastric cancer (GC) patients. Neutrophil extracellular traps (NETs) have been reported to correlate with the prothrombotic state in some diseases, but are rarely reported in GC patients.

Aim: To investigate the effect of NETs on the development of cancer-associated thrombosis in GC patients.

[Responses of the spatial distribution of to stocking rate at different scales].

We conducted an experiment to test the characteristics and differences of the spatial distribution of constructive species at different scales under different stocking rates in the desert steppe in Siziwang Banner, Inner Mongolia. The spatial distribution of under four treatments (control, light grazing, moderate grazing, and heavy grazing) at different scales (small scale as 1 m×1 m and mesoscale as 5 m×10 m) were analyzed. The results showed that the population density of at mesoscale in the control and light grazing was significantly lower than that at the small scale.

[Effects of grazing intensity on spatial heterogeneity of the constructive species Stipa breviflora in desert steppe.].

This study evaluated the changes of spatial distribution of the constructive species Stipa breviflora in the desert steppe under different grazing intensities (control, light, moderate, and heavy grazing) in Siziwang, Inner Mongolia. The small-scale spatial distribution of S. breviflora was measured.

Ultrasonic-assisted synthesis of 1,4-disubstituted 1,2,3-triazoles via various terminal acetylenes and azide and their quorum sensing inhibition.

An efficient synthesis of 1,4-disubstituted 1,2,3-triazole derivatives was studied. 1,4-Disubstituted 1,2,3-triazoles containing isoxazole and thymidine structures were synthesized in 84-96% yields starting from various terminal isoxazole ether alkynes and β-thymidine azide derivatives via a 1,3-dispolar cycloaddition using copper acetate, sodium ascorbate as the catalyst under ultrasonic assisted condition. All the target compounds were characterized by HRMS, FT-IR, H NMR and C NMR spectroscopy.

Metal-catalyzed formation of 1,3-cyclohexadienes: a catalyst-dependent reaction.

A metal-dependent and complementary catalytic method to synthesize the cyclohexadienes has been developed. When gold or indium salts were used as catalysts, 1,3-cyclohexadiene (1,3-CHD) could be obtained; when Cu(OTf)2 was used as the catalyst, however, another isomer 2,4-cyclohexadiene (2,4-CHD) was furnished instead.

[Resolution of overlapping Raman signals based on an adaptiveI immune algorithm].

Raman spectroscopy can be used in situ real-time measurement because it's rapid, and it is helpful to real-time online monitoring of process control. With the complexity of the environment and the characteristics of Raman signal, it is hard to avoid some overlapping spectrum peaks. Based on the advantage of immune algorithm, an immune algorithm (IA) was applied to the overlapping Raman signals of aromatics.

Copper(I) and silver(I) 2-methylimidazolates: extended isomerism, isomerization, and host-guest properties.

Syntheses, structures, and properties of univalent coinage metal 2-methylimidazolate supramolecular isomers [M(mim)] (1, M = Cu; 2, M = Ag) were investigated in detail. In addition to the known isomers, namely, zigzag chains [Cu(mim)] (1a) and [Ag(mim)] (2a), molecular octagon [Cu(8)(mim)(8)]·C(6)H(6) (1b), decagon [Cu(10)(mim)(10)]·C(8)H(10) (1c), helical chain [Ag(4)(mim)(4)]·C(6)H(6) (2b), and S-shaped chain [Ag(4)(mim)(4)]·C(8)H(10) (2c), two new structures including a polyrotaxane [Cu(10)(mim)(10)]·[Cu(mim)] (1d, C2/m, a = 14.452(4) Å, b = 27.
