Developing highly efficient bimetallic metal-organic frameworks (MOFs) as catalysts for Fenton-like reactions holds significant promise for decontamination processes. Although MOFs with excellent decontamination capabilities are achievable, ensuring their long-term stability, especially in the organoarsenic harmless treatment, remains a formidable challenge. Herein, we proposed a unique nanoconfinement strategy using graphene oxide (GO)-supported Prussian blue analogs (PBA) as catalytic membrane, which modulated the peroxymonosulfate (PMS) activation in p-arsanilic acid (p-ASA) degradation from traditional radical pathways to a synergy of both radical and non-radical pathways.

Programmable control of bacterial gene expression holds great significance for both applied and academic research. This is particularly true for Streptomyces, a genus of Gram-positive bacteria and major producers of prodigious natural products. Despite that a few inducible regulatory systems have been developed for use in Streptomyces, there is an increasing pursuit to augment the toolkit of high-performance induction systems.

Background: The impact of gut microbiome on hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) is unclear. We aimed to evaluate the potential correlation between gut microbiome and HBV-related HCC and introduced novel machine learning (ML) signatures based on gut microbe to predict the risk of HCC.
Materials And Methods: A total of 640 patients with chronic liver diseases or HCC were prospectively recruited between 2019 and 2022.
The long-term mining of vanadium-titanium (V-Ti) magnetite has generated a large accumulation of tailings, which can lead to metal pollution via microbial bioleaching. Current research has focused on the bioleaching of minerals, and a few studies have explored microbial responses to metals only through limited metabolite concentrations. However, the trigger mechanisms of metal release during the V-Ti magnetite tailing bioleaching and key gene regulatory pathways for organic acid metabolism are still unclear.

targeted mutagenesis technologies are the basis for the continuous directed evolution of specific proteins. Here, an efficient mutagenesis system (CgMutaT7) for continuous evolution of the targeted gene in was developed. First, cytosine deaminase and uracil-DNA glycosylase inhibitor were sequentially fused to T7 RNA polymerase using flexible linkers to build the CgMutaT7 system, which introduces mutations in targeted regions controlled by the T7 promoter.

Patients with primary central nervous system lymphoma with double expressor (DE-PCNSL) have been reported to have a higher risk of recurrence and a worse prognosis than those with PCNSL without double expressor (non-DE-PCNSL). The aim of this study was to determine whether DE-PCNSL has characteristic clinical and MR imaging features compared to non-DE-PCNSL.

The quantitative assessment without radiation can be achieved by ultrashort echo time (UTE) magnetic resonance imaging (MRI), where double-echo UTE has high clinical feasibility. However, related studies have mainly focused on distal extremities, and there is a lack of studies on the proximal femur.

Due to its high tissue contrast and spatial resolution, it is considered as an MRI sequence in diagnostic tasks related to Alzheimer's disease (AD). Thus far, most studies based on sMRI have only focused on pathological changes in disease-related brain regions in Euclidean space, ignoring the association and interaction between brain regions represented in non-Euclidean space.

A rapid and accurate diagnosis is the key, specifically for time-critical reperfusion therapies. Successful reperfusion of salvageable penumbra can reduce the extent of ischemic stroke and thus improve clinical outcomes, whereas reperfusion of irreversibly affected brain tissue is thought to be futile and may result in harm due to the risk of hemorrhagic transformation.

Typically, a liver HG has higher apparent diffusion coefficient (ADC) and T2 values than those of hepatocellular carcinomas (HCCs) and liver metastases, and lower ADC and T2 values than those of liver simple cysts. However, a portion of HGs shows ADC and T2 overlapping with those of HCC, liver metastasis, and simple cyst.

However, the low electromechanical conversion efficiency characteristic of standard QTF limits the further enhancement of the system. Therefore, the optimized design for QTF is becoming an important approach to improve the performance of QEPAS.

Objective: To explore the protective effect and mechanism of acetate on sepsis-induced acute kidney injury (AKI) in rats.
Methods: Male Sprague-Dawley (SD) rats were divided into sham operation group (Sham group), sepsis group caused by cecal ligation and puncture (CLP group), and acetate pretreatment group [NaA group, gavage sodium acetate (NaA) 300 mg/kg twice a day for 7 consecutive days before CLP] using a random number table method, with 7 rats in each group. The blood was taken from the main abdominal artery 24 hours after modeling, and renal tissue was collected from the rats.
Background: No authoritative books or guidelines are currently available for revealing the interrelationships of prostatitis, benign prostatic hyperplasia (BPH), and prostate cancer (PCa). Moreover, no consensus on this issue has been reached among previously published epidemiological studies or meta-analyses.
Purpose: We first took advantage of Mendelian randomization to clarify this issue and provide clinical implications for these patients' populations.

Sepsis is a severe immune response to pathogens that is associated with high mortality rate and a paucity of efficacious treatment options. It is characterized by the hyperactivation of macrophages and the occurrence of cytokine storms. Given the anti-inflammatory properties of M2 macrophages and their derived apoptotic bodies (AB), as well as the specific uptake of these by macrophages, a novel approach was employed to combine AB with artificial liposomes to create apoptotic body based biomimetic hybrid nanovesicles (L-AB).

Purpose: Accurate detection of cerebral microbleeds (CMBs) is important for detection of multiple conditions. However, CMBs can be challenging to identify on MR images, especially for distinguishing CMBs from the mimic of calcification. We performed a comparative reader study to assess the diagnostic performance of two primary MR sequences for differentiating CMBs from calcification.

Methods: A total of 40 healthy adults were enrolled and underwent comprehensive supine bicycle ESE at low altitude, including pulmonary vascular resistance (PVR), right ventricular (RV) area index at the end of diastole (RVEDAi), B-lines, and inferior vena cava (IVC) diameter.
Creating simple methods to produce antioxidant nanozymes with clear structure-activity relationships, particularly aiming to improve disinfection and create practical drug formulations for bacterial wound healing, remains a crucial challenge. Herein, we synthesized iron-loaded covalent organic framework nanospheres, which were then controllably transformed into a carbon-based nanozyme with both iron single atoms and iron clusters through simple pyrolysis. We discovered that the gradual growth of iron clusters significantly boosted the nanozyme's adsorption onto the substrate and electron transfer, greatly influencing its activity.
