Update on central factors in myopia development beyond intraocular mechanisms.

Myopia, a prevalent refractive error, primarily affects children and adolescents, characterized by excessive axial elongation causing distant objects to focus in front of the retina. This review explores the intricate mechanisms beyond intraocular factors, emphasizing the significant role of central factors in myopia development and progression. Intraocular mechanisms involving the retina, RPE/choroid, and sclera are well documented, with these structures playing crucial roles in eye growth regulation.

Tryptophan was metabolized into beneficial metabolites against coronary heart disease or prevented from producing harmful metabolites by the drug screening model based on .

In our previous study of 2,130 Chinese patients with coronary heart disease (CHD), we found that tryptophan (TRP) metabolites contributed to elevated risks of death. Many TRP-derived metabolites require the participation of intestinal bacteria to produce, and they play an important role in the pathogenesis of metabolic diseases such as CHD. So it is necessary to metabolize TRP into beneficial metabolites against CHD or prevent the production of harmful metabolites through external intervention.

Cucurbit[7]uril-Mediated Supramolecular Bactericidal Nanoparticles: Their Assembly Process, Controlled Release, and Safe Treatment of Intractable Plant Bacterial Diseases.

A safe, biocompatible, and stimuli-responsive cucurbit[7]uril-mediated supramolecular bactericidal nanoparticle was fabricated by encapsulating a highly bioactive carbazole-decorated imidazolium salt (, EC = 0.647 μg/mL against phytopathogen pv ) into the host cucurbit[7]uril (CB[7]), thereby leading to self-assembled topographies from microsheets () to nanospheroidal architectures (@CB[7]). The assembly behaviors were elucidated by acquired single-crystal structures, H NMR, ITC, and X-ray powder diffraction experiments.

Free Triiodothyronine Connected With Metabolic Changes in Patients With Coronary Artery Disease by Interacting With Other Functional Indicators.

This study aims to evaluate the association between free triiodothyronine (FT3) and outcomes of coronary artery disease (CAD) patients, as well as to assess the predictive power of FT3 and related functional markers from the perspective of potential mechanism. A total of 5104 CAD patients with an average follow-up of three years were enrolled into our study. Multivariate Cox regression was used to evaluate the associations between FT3, FT4 (free thyroxin), FT3/FT4 and death, MACE.

Expression of Bacillus thuringiensis toxin Cyt2Ba in the entomopathogenic fungus Beauveria bassiana increases its virulence towards Aedes mosquitoes.

Background: The entomopathogenic fungus Beauveria bassiana has been widely used to kill mosquito larvae and adults in the laboratory and field. However, its slow action of killing has hampered its widespread application. In our study, the B.

Cytotoxic -terphenyls from the deep-sea-derived .

From the deep-sea-derived fungus , one novel () and three known (-) -terphenyl derivates were isolated. The structure of the new compound was established mainly on the basis of extensive analysis of 1D and 2D NMR data. All four isolates were tested for anti-food allergic and antitumor bioactivities.

Cascade Reaction of Isatins with 1,1-Enediamines: Synthesis of Multisubstituted Quinoline-4-carboxamides.

A one-step methodology for the synthesis of multisubstituted quinoline-4-carboxamides was developed by simply refluxing a mixture of isatins 1 and various kinds of 1,1-enediamines 2-4 in a reaction catalyzed by NHSOH. As a result, a series of quinolone-4-carboxamides were produced through a novel cascade reaction mechanism. This reaction involved the formation of the quinoline ring accompanied by the formation of an amide bond in one step.

Memory and threshold resistance switching in Ni/NiO core-shell nanowires.

We report on the first controlled alternation between memory and threshold resistance switching (RS) in single Ni/NiO core-shell nanowires by setting the compliance current (I(CC)) at room temperature. The memory RS is triggered by a high I(CC), while the threshold RS appears by setting a low I(CC), and the Reset process is achieved without setting a I(CC). In combination with first-principles calculations, the physical mechanisms for the memory and threshold RS are fully discussed and attributed to the formation of an oxygen vacancy (Vo) chain conductive filament and the electrical field induced breakdown without forming a conductive filament, respectively.

[Concentrations and influence factors of polycyclic aromatic hydrocarbons in leaves of dominant species in the Pearl River Delta, South China].

Concentrations of PAHs in leaves of six dominant species in the Pearl River Delta of South China were determined with gas chromatography and mass spectrometry (GC-MS), and synchronously leaf-lipid contents, leaf areas, specific leaf areas (SLA) were measured. The characters of PAHs abundance and influence factors on them were investigated. The results show that concentrations of PAHs in pine needles are higher than those in broad-leaves remarkably, and the highest value (1034.
