Flavor is one of the most significant characteristics of beef palatability and it can eventually affect the consumer's acceptance of a beef product and purchasing habits. Variation in beef quality is large and is due to many factors, such as differences in genetic background, sex, age, management and nutrition. The consumer's decision to purchase beef is guided by the perception of healthiness and a variety of sensory traits including color, tenderness, juiciness, and aroma or flavor.

This study observed the functional bacteria succession related to nitrogen metabolism in EFS by high throughput sequencing, and evaluated their associations with environmental factors. Results revealed that with the changes of temperature, pH, moisture content, and nitrogen content during fermentation, the species richness and diversity of ammonia oxidizing bacteria (AOB) with amoA increased, but those of denitrifying bacteria carrying nirK and nosZ decreased.

In the present work, six citrus rbohs (Csrbohs) genes were identified in citrus, and their possible involvement in resistance to Xanthomonas citri ssp. citri (Xcc) was examined.

However, the genetic architecture of the Hui population remains largely unexplored, particularly with respect to the male-specific region of the Y chromosome. Here, we studied nine Hui populations (Xinjiang, Qinghai, Gansu, Ningxia, Shaanxi, Henan, Shandong, Sichuan, Yunnan) using 157 Y-chromosome single nucleotide polymorphisms (Y-SNPs) and 27 short tandem repeats (Y-STRs) to unravel their genetic substructure and forensic characteristics.

It is based on the use of the conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT) that is doped with the water insoluble ionic liquid (IL), 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide. A glassy carbon electrode modified with PEDOT/IL is shown to enable accurate determination of dopamine, as a model analyte in the presence of high concentrations of proteins, and resist biological fouling even in native serum.

The crystal-field levels of Ce3+ in a series of lanthanide aluminum perovskites have been investigated with reference to polyhedron deformation. For each compound, the corresponding ideal cuboctahedron is derived through a least-square procedure. The virtual energy levels of Ce3+ in these ideal polyhedrons are then obtained considering both crystal-field splitting and spin-orbit coupling.

Herein, an improved persistent luminescence of YAlGaO phosphor by co-doping Ce, Yb, and B is achieved using conventional solid-state reaction. On one hand, the incorporation of HBO can improve the crystallinity; on the other hand, B can replace Al/Ga in tetrahedral sites in the host lattice, causing lattice contraction and modifying the trap depth and density.

Early afterdepolarizations (EADs) are spontaneous depolarizations during the repolarization phase of an action potential in cardiac myocytes. It is widely known that EADs are promoted by increasing inward currents and/or decreasing outward currents, a condition called reduced repolarization reserve. Recent studies based on bifurcation theories show that EADs are caused by a dual Hopf-homoclinic bifurcation, bringing in further mechanistic insights into the genesis and dynamics of EADs.

The interaction between pyridoxal hydrochloride (HQ) and apoCopC was investigated using Fourier transform infrared spectroscopy (FTIR), isothermal titration calorimetry (ITC), circular dichroism (CD), fluorescence spectroscopy, three-dimensional (3D) fluorescence spectroscopy, fluorescence lifetime, TNS fluorescence and docking methods. FTIR, CD, TNS fluorescence and fluorescence lifetime experiments suggested that the apoCopC conformation was altered by HQ with an increase in the random coil content and a reduction in the β-sheet content. In addition, the data from fluorescence spectroscopy, 3D fluorescence spectroscopy and molecular docking revealed that the binding site of HQ was located in the hydrophobic area of apoCopC, and a redshift of the HQ fluorescence spectra was observed.

The authors describe a fluorescent system composed of graphene quantum dots (GQDs) as NIR emitters, and novel MnO nanoflowers as the fluorescence quenchers. The system is shown to be an activatable and biodegradable fluorescent nanoprobe for the "turn-on" detection of intracellular glutathione (GSH).

However, as hole-oxidation reaction occurs at the photoanode interface, the photoanode-based PEC sensor has inferior anti-interference capacity to reductive substances coexisting in the biological sample, leading to a challenged selectivity. Herein, a universal design on selectivity-enhanced PEC enzyme sensor was proposed by integrating a photoanode with a biocathode.

In this study, we initially determined that a new molecular immunopotentiator, ophiopogonin D (OP-D), enhanced the antibody response to antigen. Because OP-D has certain disadvantages, including poor solubility, we next encapsulated OP-D in a nanoemulsion adjuvant (nanoemulsion-encapsulated OP-D, NOD) using low-energy emulsification methods.

In the latter respect, the recent discovery of a non-structural AAV protein, termed assembly-activating protein (AAP), has shed new light on the processes involved in assembly of the viral capsid VP proteins into a capsid. Although many AAV serotypes require AAP for assembly, we have recently reported that AAV4, 5, and 11 are exceptions to this rule.
