Research Progress on Gene Synthesis and Anticancer and Lipid-lowering Mechanism of Monacolin K.

Monacolin K (MK), also known as lovastatin (LOV), is a secondary metabolite synthesized by Monascus in the later stage of fermentation and is the main component of functional red yeast rice (RYR). The structure of MK is similar to 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA), and it can competitively bind to 3-hydroxy-3- methylglutaryl coenzyme A reductase (HMGCR), thus reducing the level of blood lipids. MK can affect the expression of MAPK, PI3K/AKT, and NF-κB pathway, prepare conjugates with other compounds, and enhance the sensitivity of cancer cells to chemotherapeutic drugs so as to induce apoptosis of acute myeloid leukemia, prostate cancer, breast cancer, lung cancer, gastric cancer, and liver cancer.

Preparation of Environmentally Friendly Glueless Boxwood Timber by Acidic Environmental Treatment and High-Temperature Pressing.

In the context of high-quality development, environmental issues are being paid more and more attention to, and the release of free formaldehyde has become a major problem that needs to be solved. Glueless plywood mainly adopts natural substances as raw materials, without adding chemical products, such as resin adhesives, and it does not contain harmful substances, such as formaldehyde. Glueless plywood is a green product that causes no pollution in the environment and no harm to the human body.

Zn and Ni dual hydrogen evolution sites integrated onto CdS for effective photocatalytic hydrogen production.

Effective and affordable photocatalysts play an important role in the cost reduction of solar hydrogen production through photocatalytic water splitting. In this research, a Zn and Ni modified carbon hydrogen evolution cocatalyst (ZnNi-C) were synthesized and immobilized onto the surface of CdS (CdS@ZnNi-C) for photocatalytic hydrogen evolution (PHE). The preparation used an ethylenediaminetetraacetic acid disodium (EDTA)-assisted method.

NiFe-bimetal-organic framework grafting oxygen-vacancy-rich BiVO photoanode for highly efficient solar-driven water splitting.

Bismuth vanadate (BVO) possesses great potential in photoelectrochemical water splitting application, but still suffers from low charge transfer efficiency as well as poor chemical stability. Herein, we have fabricated a thin NiFe-bimetal-organic framework (NiFe-MOF) layer grafting surface oxygen vacancies enriched BVO photoanode (NiFe-O-BVO), which improves the charge separation and transfer efficiency during oxygen evolution process. Meanwhile, the NiFe-MOFs thin layer can not only protect the surface O of BVO, but also efficiently inhibits the photocorrosion.

Vibronic Coupling Effect on the Vibrationally Resolved Electronic Spectra and Intersystem Crossing Rates of a TADF Emitter: 7-PhQAD.

Assessing and improving the performance of organic light-emitting diode (OLED) materials require quantitative prediction of rate coefficients for the intersystem crossing (ISC) and reverse ISC (RISC) processes, which are determined not only by the energy gap and the direct spin-orbit coupling (SOC) between the first singlet and triplet excited-states at a thermal equilibrium position of the initial electronic state but also by the non-Condon effects such as the Herzberg-Teller-like vibronic coupling (HTVC) and the spin-vibronic coupling (SVC). Here we apply the time-dependent correlation function approaches to quantitatively calculate the vibrationally resolved absorption and fluorescence spectra and ISC/RISC rates of a newly synthesized multiple-resonance-type (MR-type) thermally activated delayed fluorescence (TADF) emitter, 7-phenylquinolino[3,2,1-]acridine-5,9-dione (7-PhQAD), with the inclusion of the Franck-Condon (FC), HTVC, and Duschinsky rotation (DR) effects. The SVC effect on the rates has also been approximately evaluated.

An Atomistic-Based Nonlinear Plate Theory for Hexagonal Boron Nitride.

Through the continuity of the DREIDING force field, we propose, for the first time, the finite-deformation plate theory for the single-layer hexagonal boron nitride (h-BN) to clarify the atomic source of the structure against deformations. Divergent from the classical Föppl-von Karman plate theory, our new theory shows that h-BN's two in-plane mechanical parameters are independent of two out-of-plane mechanical parameters. The new theory reveals the relationships between the h-BN's elastic rigidities and the atomic force field: (1) two in-plane elastic rigidities come from the bond stretching and the bond angle bending; (2) the bending rigidity comes from the inversion angle and the dihedral angle torsion; (3) the Gaussian rigidity only comes from the dihedral angle torsion.

Vertical 2-dimensional heterostructure SnS-SnS with built-in electric field on rGO to accelerate charge transfer and improve the shuttle effect of polysulfides.

Traditional carbon materials as sulfur hosts of Li-sulfur(Li-S) cathodes have slightly physical constraint for polysulfides, due to their no-polar property. Therefore, it is necessary to further enhance the affinity between sulfur hosts and polysulfides, and relieve the shuttle effects in the Li- S batteries. Herein, we report a novel vertical 2-dimensional (2D) p-SnS/n-SnS heterostructure sheets which grown on the surface of rGO.

The ontogenesis of catabolic abilities and energy metabolism during endogenous nutritional periods of tongue sole, Cynoglossus semilaevis.

The ontogenesis of catabolic abilities and energy metabolism during endogenous nutritional periods of tongue sole was investigated. In this work, trypsin-like proteases (TRY) and triglyceride lipase (LIP) activities were measured to assess the capacities to catabolize proteins and lipids, respectively. Meanwhile, specific enzymes including pyruvate kinase (PK), glutamic oxalo acetic transaminase (GOT) and glutamate dehydrogenase (GDH), and hydroxyacyl CoA dehydrogenase (HOAD) as well as their ratios were assayed to evaluate the abilities to use energy substrates of carbohydrates, amino acids and fatty acids, respectively, for energy production.

Biodegradation potential of polycyclic aromatic hydrocarbons in Taihu Lake sediments.

To assess the biodegradation potential of polycyclic aromatic hydrocarbons (PAHs) in sediments, sediment microcosms were constructed with sediments collected from six lake zones with different trophic statuses in Taihu Lake.

After 85 d of aerobic and anaerobic incubation, spiked PAHs (phenanthrene, pyrene, and benzo[]pyrene) were partially degraded by indigenous sediment microorganisms.
