Nutrient distribution and nitrate processing in a mangrove tidal creek affected by submarine groundwater discharge (SGD).

Investigations of the spatial-temporal variations of nutrients within mangrove coastal zones are essential for assessing the environmental status of an aquatic ecosystems. However, major processes controlling nitrate cycle along the submarine groundwater discharge (SGD) pathway from the mangrove areas to adjacent tidal creek remain underexplored. A time series measurement over a 25 h tidal cycle was conducted in Qinglan Bay tidal creek (Hainan Island, China).

Centering historically minoritized populations to design effective messages about an evidence-based policy to advance social equity.

Researchers have raised concerns that messages describing racial disparities in social outcomes can reduce or polarize support for public policies to address inequality. We questioned this assumption by testing the impact of carefully crafted messages about child tax credit (CTC) expansion. We conducted two randomized message trials, study 1 using Prolific's nonprobability panel ( = 1,402) and study 2 using SSRS's Opinion Panel, a web-based probability sample of US adults ( = 4,483).

Portable and real-time detection for tetracycline antibiotics using europium-doped LDH gel intercalated graphene quantum dots.

Tetracyclines (TCs) residues pose a significant threat to the aquatic environment and human health, therefore this study aims to develop a simple, rapid, and sensitive TCs detection method.

Role of high-resolution magnetic resonance imaging in preoperative tumor-node-metastasis staging evaluation of esophageal cancer: a narrative review.

Background And Objective: Esophageal cancer (EC) is an aggressive disease characterized by high mortality rates and a propensity for locoregional or distant recurrence. The treatment strategies and prognostic estimation for EC depend on accurate pre-treatment tumor-node-metastasis (TNM) staging. The objective of this review was to illustrate the role of various imaging modalities in achieving accurate preoperative TNM staging of EC, with a particular focus on the utilization of advanced high-resolution magnetic resonance imaging (MRI) sequences for T classification, which have shown promise in enhancing the delineation of tumor depth and extent.

Genetic syndromes associated with pancreatic neuroendocrine neoplasms and imaging diagnostic strategies.

Pancreatic neuroendocrine neoplasms (pNENs) are the second most common pancreatic malignancy. While most cases are sporadic, a small proportion is associated with genetic syndromes, such as Multiple Endocrine Neoplasia (MEN), Von Hippel-Lindau Syndrome (VHL), Neurofibromatosis Type 1 (NF1), and Tuberous Sclerosis Complex (TSC). This review aims to use pNENs as a clue to reveal the full spectrum of disease, providing a comprehensive understanding of diagnosis.

Pd/Cu-TCPP(Fe)-polydopamine mediated magnetic relaxation switching immunosensor for sensitive detection of chlorpyrifos.

This study presents the development of a magnetic relaxation switching (MRS) immunosensor for the sensitive detection of chlorpyrifos (CPF) with a signal amplification strategy using Pd/Cu-TCPP(Fe) hybrid nanosheets and polydopamine (PDA). Pd/Cu-TCPP(Fe) nanosheets, which exhibit high peroxidase-like activity and excellent storage stability, making them suitable replacements for natural enzymes in biosensors, are further functionalized with goat anti-mouse IgG (Ab) to construct an immunosensor. The mechanism relies on the competition between free CPF and the immobilized bovine serum albumin-CPF conjugates for antibody binding, which modulates the aggregation of magnetic nanoparticles (MNPs) that are related to the transverse relaxation time.

Ischemic Stroke Induces ROS Accumulation, Maladaptive Mitophagy, and Neuronal Apoptosis in Minipigs.

Reactive oxygen species (ROS)-induced adaptive/maladaptive mitophagy plays an essential role in the pathophysiology of acute ischemic stroke (AIS).

In this study, we aimed to develop porcine models of permanent stroke and observe the pathophysiological alterations caused by acute ischemic stroke, focusing on ROS-induced mitophagy.

DMEDH: diffusion model-boosted multiplane extrapolation for digital holographic reconstruction.

Digital holography can reconstruct the amplitude and phase information of the target light field. However, the reconstruction quality is largely limited by the size of the hologram. Multi-plane holograms can impose constraints for reconstruction, yet the quality of the reconstructed images continues to be restricted owing to the deficiency of effective prior information constraints.

Preparation, characterization and mechanism of SiO@SiO core-shell microspheres through polymerization-induced colloid aggregation for fast separation using ultra performance liquid chromatography.

The polymerization-induced colloid aggregation (PICA) method is commonly used to create SiO@SiO core-shell silica microspheres (CSSMs), but it often encounters challenges such as incomplete shell coating and poor reproducibility. In this paper, the formation mechanism of the silica shell layer during the preparation of SiO@SiO CSSMs using the PICA method was investigated. It was found that ureido modification can reduce the Zeta potential of the silica core surface, facilitating the deposition of coacervates formed by urea-formaldehyde resin (UF) and silica nanoparticles on the silica core surface to form the SiO shell layer when the Zeta potential of the surface is in the range of -20.

Influence of the Pt/ionomer/water interface on the oxygen reduction reaction: insights into the micro-three-phase interface.

Understanding the Pt/ionomer/water interface structure and its impact on the oxygen reduction reaction (ORR) activity is essential for enhancing catalyst utilization and performance of fuel cells. This study aimed to investigate the influence of sulfonic acid groups on the Pt/ionomer/water interface and the ORR mechanism. By using a combination of DFT, AIMD, and microkinetic simulations, the results showed that when the sulfonic acid group is located at the edge of the Helmholtz plane, it creates an optimal three-phase interface, providing more available active sites, a stronger interfacial electric field, and a more continuous H-bond network.

The spatial distribution pattern of agricultural soil heavy metals (SHMs) content in Lintong, a typical river valley city in China, was determined and the degree of contamination was evaluated. A scientific source apportionment methodological framework was constructed through correlation analysis methods together with multiple source apportionment receptor models.

Bovine serum albumin framed activatable NIR AIE photosensitizer for targeted tumor therapy.

Organic near-infrared (NIR) photosensitizers (PS) largely facilitate photodynamic therapy (PDT). To overcome aggregation induced quenching and diminishment of reactive oxygen species (ROS) generation capability of NIR-PS, aggregation-induced emission (AIE) effect groups have been introduced to generate NIR AIE photosensitizers. However, currently reported NIR AIE photosensitizers all take "always-on" activity that may cause systemic phototoxic side effects.
