As the most effective way to remedy and reconstruct the degraded ecosystems, vegetation restoration could affect soil carbon and nitrogen cycles and water balance. We examined the responses of carbon, nitrogen, and water in 0-200 cm soil layer to vegetation restoration years by analyzing their distribution characteristics across a restoration chronosequence of plantation (5, 10, 15, 20, and 25 years) in alpine sandy region of the Qinghai-Tibetan Plateau. The results showed that the content and storage of soil organic carbon (SOC) and soil total nitrogen (STN) increased significantly, while that of soil inorganic carbon (SIC) decreased significantly with restoration years.

However, the current planning still heavily relies on manual interventions, which is labor-intensive, experience-dependent, and poorly reproducible. Therefore, we propose ZygoPlanner, a pioneering efficient preoperative planning framework for zygomatic implantation, which may be the first solution that seamlessly involves the positioning of zygomatic bones, the generation of alternative paths, and the computation of optimal implantation paths.

Methods: In this study, inoculated with or without AMF () under different Mn concentrations (0 mmol/L, 1 mmol/L, 5 mmol/L, 10 mmol/L, and 20 mmol/L) was cultivated via a pot experiment, and plant biomass, physiological and biochemical characteristics, manganese absorption, subcellular distribution, and chemical forms of Mn were examined.
Results: The results showed that root biomass, stem biomass, leaf biomass, and total individual biomass decreased under high Mn concentrations (above 10 mmol/L), and the inoculated plants had higher biomass than the uninoculated plants.
Objectives: This study aims to characterize the bacterial co-occurrence features and potential interactions associated with the presence of sinus tracts in apical periodontitis in a Chinese population by using 16S rRNA next-generation sequencing (NGS).
Methods: Thirty-one samples from twenty-six patients were collected from root canals. Following the extraction of the bacterial DNA, the V3-V4 hypervariable regions of the 16S rRNA gene were sequenced.
Osteoporosis, a metabolic disorder, remains challenging to treat due to limited understanding of its underlying mechanism. The annual cycle of "cyclic physiological osteoporosis (CPO)" and its full reversal in male deer represents a unique natural model for studying this condition. Deer antlers, weighing up to 25 kg/pair, derive over 60% of their mineral contents from deer skeleton during mineralization.

In a previous study, highly dispersible AgNPs were fabricated using a polysaccharide-protein complex (PSP) obtained from the viscera . In this study, the antibacterial activity of PSP-AgNPs against pathogenic and its cytotoxicity for human hepatocytes (LO2) was evaluated.

The aim of this study was to elucidate the regulatory mechanism affecting AsA metabolism in cucumber fruit. In this study, the AsA content in the fruit of two cucumber cultivars (H28 and H105) was significantly higher in the exocarp and endocarp than in the mesocarp.

Data Sources: A comprehensive search was conducted in PubMed, Web of Science, Scopus, and the Cochrane Library. No language restrictions were applied.
Breast cancer remains the most prevalent malignancy among women globally, presenting significant challenges in therapeutic strategies due to tumor heterogeneity, drug resistance, and adverse side effects. Recent advances in targeted therapies, particularly antibody-drug conjugates (ADCs), have shown promise in addressing these challenges by selectively targeting tumor cells while sparing normal tissues. This study provides a comprehensive analysis of two innovative ADCs targeting HER2 and Trop-2, which are critical markers in various breast cancer subtypes.

To date, they had not been reported in metal nanoparticles smaller than 2 nm owing to the difficulty in characterization and the high instability of grain boundary (GB) atoms. Herein, we have successfully developed a synthesis method for producing a novel chiral nanocluster Au(TBBT) (TBBT=4-tert-butylphenylthiolate) with a 26-atom gapped and rotated GB.

Methods: This is a prospective observational cohort study investigating whether sling surgery or PFME is preferred for pre-menopause women with moderate uncomplicated SUI. Those who received PFME alone or sling surgery were divided to PT or TVT group, respectively.
Hexavalent chromium [Cr (VI)] has been identified as a human carcinogen and environmental pollutant capable of affecting multiple systems in the human body. However, the specific mechanisms by which Cr (VI) affects the human nervous system remain unclear. Following confirmation of Cr (VI)'s toxic effects on rat astrocytes, this study explores the metabolites and associated metabolic pathways of rat astrocytes under different doses of Cr (VI) exposure.

Herein, we concurrently synthesized two novel rod-shaped Au nanoclusters, Au(PET) and Au(PET) (PET = 2-phenylethanethiolate), and precisely revealed that their kernels were 4 × 4 × 6 and 5 × 4 × 6 face-centered cubic (fcc) structures, respectively, based on the numbers of Au layers in the [100], [010], and [001] directions. Following the structural growth mode from Au(PET) to Au(PET), we predicted six more novel nanoclusters.

Monocyte-derived tumor-associated macrophages (Mo-TAMs) intensively infiltrate diffuse gliomas with remarkable heterogeneity. Using single-cell transcriptomics, we chart a spatially resolved transcriptional landscape of Mo-TAMs across 51 patients with isocitrate dehydrogenase (IDH)-wild-type glioblastomas or IDH-mutant gliomas. We characterize a Mo-TAM subset that is localized to the peri-necrotic niche and skewed by hypoxic niche cues to acquire a hypoxia response signature.
