[Quantitative classification and biodiversity characteristics of plant communities in Luoshan Mountain steppe, Ningxia, China].

To understand the distribution pattern and influencing factors of plant community and diversity along the altitude gradient, we examined plant community types, plant diversity and phylogenetic diversity of mountain steppe in Luoshan, Ningxia, and analyzed the relationship between the plant community and its diversity and environmental driving factors. The results showed that the main community types in the mountain steppe were community, community, community, community, ＋ community, community, ＋＋ community, ＋ community, ＋ community, community, community and community. The distribution of mountain steppe community was mainly affected by altitude, soil alkali-hydrolyzed nitrogen, water content, available potassium, silt and organic matter contents, with altitude and soil water content having the greatest effects (<0.

Use of fluoroquinolones and risk of rhegmatogenous retinal detachment: a retrospective cohort study using two nationwide representative claims databases.

Tumor-Targeted Magnetic Micelles for Magnetic Resonance Imaging, Drug Delivery, and Overcoming Multidrug Resistance.

Nasopharyngeal carcinoma (NPC) is prevalent in Southern China. Unfortunately, current treatments encounter multidrug resistance (MDR). Overexpression of P-glycoprotein (P-gp), resulting in the efflux of chemotherapy drugs, is one of the significant mechanisms causing MDR.

Characterization and functional analysis of a novel goose-type lysozyme from teleost Sebastes schlegelii with implications for antibacterial defense and immune cell modulation.

Lysozymes are crucial enzymes involved in the innate immune response against bacterial pathogens. In this study, we identified and characterized a goose-type lysozyme gene (SsLyG) from the black rockfish Sebastes schlegelii, an economically important aquaculture species. The deduced amino acid sequence of SsLyG contains 495 residues, which inculded a signal peptide, an immunoglobulin domain, and a goose egg-white lysozyme (GEWL) domain.

Stepwise extraction of zinc, indium and lead from secondary zinc oxide dusts experimental study.

Secondary zinc oxide dust is rich in high-grade metals such as Zn, In, Pb, and Ga, and in the face of the depletion of ore resources at home and abroad, it is of great significance to seek an efficient process to realize the full resource recovery of valuable metals in secondary zinc oxide dust. In this study, on the basis of the thermodynamic analysis of the wet treatment process, three wet treatment methods, namely "low acid leaching", "high acid leaching" and "chlorination leaching", were used to explore the suitable parameters for stepwise extraction of Zn, In and Pb metals. The results showed that the three wet treatment methods could effectively extract the corresponding main elements, and the optimal leaching rates of Zn, In and Pb were 73, 90 and 94%, respectively.

Advancing prognostic precision in gastric cancer with an immunoinflammatory index.

Gastric cancer remains a major global health challenge with high morbidity and mortality rates. Recent advancements in immunology and inflammation research have highlighted the crucial roles that these biological processes play in tumor progression and patient outcomes. This has sparked new interest in developing prognostic biomarkers that integrate these two key biological processes.

Postoperative peritumoral edema is correlated with the prognosis in intracranial meningioma with preoperative peritumoral edema.

Preoperative peritumoral edema (PTE) in intracranial meningiomas is known to be a risk factor for postoperative recurrence. However, there are two groups: those in which preoperative PTE remains and those in which preoperative PTE receded after tumor removal. We aimed to investigate whether postoperative PTE could improve the prediction of prognosis of meningioma with preoperative PTE.

Targeting chaperone-mediated autophagy in neurodegenerative diseases: mechanisms and therapeutic potential.

The pathological hallmarks of various neurodegenerative diseases including Parkinson's disease and Alzheimer's disease prominently feature the accumulation of misfolded proteins and neuroinflammation. Chaperone-mediated autophagy (CMA) has emerged as a distinct autophagic process that coordinates the lysosomal degradation of specific proteins bearing the pentapeptide motif Lys-Phe-Glu-Arg-Gln (KFERQ), a recognition target for the cytosolic chaperone HSC70. Beyond its role in protein quality control, recent research underscores the intimate interplay between CMA and immune regulation in neurodegeneration.

Reciprocal or nonreciprocal bimolecular interface and quantum entanglement.

We study a hybrid system of a plasmonic cavity coupled to a pair of different molecular vibration modes with the strong optomechanical-like interactions. Here, this plasmonic cavity is considered as a quantum data bus and then assist several applications. For instance, it can first establish a bimolecular interface to ensure the reciprocal or non-reciprocal information transmission, and then engineer both molecules into the steady-state quantum entanglement of the continuous variable through the dissipative method.

Hierarchically porous and flexible chitin-fiber/melamine-sponge composite filter with high-loading of PdAu nanoparticles for effective hydrodechlorination of chlorophenols.

Hydrodechlorination has emerged as a promising technique for detoxifying chlorophenols (CPs) in wastewater, but it suffers from sluggish reaction kinetics and limited durability due to the lack of effective and stable catalysts. Herein, a composite filter consisting of melamine-sponge (MS), chitin fiber (CF) and ultrafine PdAu nanoparticles (PdAu/CF-MS) has been designed for continuous hydrodechlorination of CPs by using formic acid as a H-donor and sodium formate as a promoter. Benefitting from the dense active sites, rich porosity, and synergetic interaction of Pd/Au, the PdAu/CF-MS filter exhibits excellent hydrodechlorination performance (∼ 100 % conversion) towards 4-chlorophenol (1 mM, fluxes below 6100 mL·h·g) and outstanding durability (over 500 h at 61 mL·h·g), surpassing most reported counterparts (usually deactivated within 200 h or several cycles).
