Research on Rapid and Non-Destructive Detection of Prune Brix Based on Visible/Near-Infrared Spectroscopy Technology.

Prunes, known for their sweet aroma and smooth texture, are rich in vitamins and minerals, making them both a delicious and nutritious food. Brix is a key indicator of prune quality; however, rapid and nondestructive measurement remains a challenge. About this research, visible/near-infrared (Vis/NIR) spectral data from various prune types were collected and preprocessed using Standard Normal Variate (SNV) to reduce noise and scattering effects.

Stress-Strain and Structural Evolution on the Localized Interface of Stainless Steel Clad Plate.

By applying different heat treatment processes (furnace cooling, air cooling, and water cooling), the stress-strain behavior of the localized interfacial region in weathering steel-stainless steel clad plates was investigated using nanoindentation, along with an analysis of interfacial microstructure formation and strengthening mechanisms. The results show that samples in the as-rolled (R), furnace-cooled (FC), air-cooled (AC), and water-cooled (WC) conditions exhibit distinct interfacial morphologies and local mechanical properties. A well-defined interfacial layer forms between the base and cladding materials, where a high density of dislocations, grain boundaries, precipitates, and nanoscale oxides significantly enhances interfacial strength, resulting in a yield strength () much higher than that of either adjacent metal.

Docosahexaenoic Acid Modulates Nonalcoholic Fatty Liver Disease by Suppressing Endocannabinoid System.

Scope: Endocannabinoid signaling regulates energy homeostasis, and is tightly associated with nonalcoholic fatty liver disease (NAFLD). The study previously finds that supplementation of docosahexaenoic acid (DHA) has superior function to ameliorate NAFLD compared with eicosapentaenoic acid (EPA), however, the underlying mechanism remains elusive. The present study aims to investigate whether DHA intervention alleviates NAFLD via endocannabinoid system.

Simultaneous Extraction and Determination of Lignans from (Turcz.) Baill. via Diol-Based Matrix Solid-Phase Dispersion with High-Performance Liquid Chromatography.

The quality of (Turcz.) Baill. () is principally attributed to lignan compounds.

Effect of Lard or Plus Soybean Oil on Markers of Liver Function in Healthy Subjects: A Randomized Controlled-Feeding Trial.

Humans have consumed lard for thousands of years, but in recent decades, it has become much less popular because it is regarded as saturated fat. Animal studies showed that lard plus soybean oil (blend oil) was more advantageous for liver health than using either oil alone. This study aims to assess the effects of blend oil on liver function markers in healthy subjects.

[Simultaneous determination of five lignans from by matrix solid-phase dispersion extraction-high performance liquid chromatography].

The kidney-shaped, red-colord fruit from the plant, (Turcz.) Baill, which belongs to the Schisandraceae family, is among the most popular remedies used in traditional Chinese medicine. The English name of the plant is "Chinese magnolia vine".

Functionalized nickel(II)-iron(II) dithiolates as biomimetic models of [NiFe]-Hases.

To develop the structural and functional modeling chemistry of [NiFe]-Hases, a series of new biomimetics for the active site of [NiFe]-Hases have been prepared by various synthetic methods. Treatment of the mononuclear Ni complex (pnp)NiCl (pnp = (PhPCH)NPh) with (dppv)Fe(CO)(pdt) (dppv = 1,2-(PhP)CH, pdt = 1,3-propanedithiolate) and KPF gave the dicarbonyl complex [(pnp)Ni(pdt)Fe(CO)(dppv)](PF) ([1](PF)). Further treatment of [1](PF) and [(dppe)Ni(pdt)Fe(CO)(dppv)](BF) (dppe = 1,2-(PhP)CH) with the decarbonylation agent MeNO and pyridine afforded the novel sp C-Fe bond-containing complexes [(pnp)Ni(SCHCHCHS)Fe(CO)(dppv)]PF ([2]PF) and [(dppe)Ni(SCHCHCHS)Fe(CO)(dppv)]BF ([3]BF).

Synthesis of Aryl-methylene Ethers through Pd(0)-Catalyzed Coupling between Hydrobenzoxazoles and Dichloromethane.

Using dichloromethane (DCM) as the C1 feedstock, the first Pd(0)-catalyzed synthesis of aryl-methylene ether motifs from hydrobenzoxazoles (hydrothiazoles) has been reported. This protocol has exhibited an ample substrate scope (38 examples) and wide functional group tolerance. Aryl-methylene ether adducts have been successfully engaged in coupling with isocyanate to provide bis-iminoisoindolinones.

Biomimetic models of [Fe]-hydrogenase featuring a 2-acylphenylthiomethyl-6-R-pyridine (R = H or OMe) ligand.

Despite a variety of [Fe]-Hase models prepared so far, the structural and functional modeling study of the enzyme has remained a great challenge. Now, we report a new type of flexible pyridine ligand (FPL)-based synthetic method by which two novel [Fe]-Hase models have been prepared. Notably, the two models contain not only a biomimetic -acyl C, pyridyl N, thioether S coordination mode but also possess the enzyme-like H/D activation functions.

Theoretical design and preparation research of molecularly imprinted polymers for steviol glycosides.

In this paper, a novel molecularly imprinted polymer (MIP) for specific adsorption of steviol glycosides was designed, and the imprinting mechanism of self-assembly system between template and monomers was clearly explored. Firstly, steviol (STE) was chosen as dummy template, and the density functional theory (DFT) at B3LYP/6-31 + G (d, p) level was used to select monomers, imprinting molar ratios, solvents, and cross-linking agents. The selectivity to five steviol glycosides was also calculated.

Clinical prognostic model for older patients with advanced non-small cell lung cancer.

Background: Older patients with non-small cell lung cancer (NSCLC) are often not prescribed standard therapy. It is important to know which older patients would be candidates for aggressive therapy based on their prognosis, and to develop a model that can help determine prognosis.

Methods: Data on older patients (≥70 years) enrolled on 38 NCI cooperative group trials of advanced NSCLC from 1991 to 2011 were analyzed.
