Purpose: The study aimed to investigate the effect and mechanism of monotropein on renal cell carcinoma (RCC).

Methods: After monotropein and NF-κB receptor activator (RANKL) treatment, cell proliferation, invasion, and apoptosis were evaluated using CCK-8, Transwell, and flow cytometry. Primary macrophages co-cultured with monotropein-treated RCC cells were analyzed to evaluate macrophage polarization using qRT-PCR, western blot, and ELISA assays by detecting the expression of M2 markers (CD206, CD168) and cytokines (IL-10, TGF-β).

Microplastics are widely present in the environment and can adversely affect plants. In this paper, the effects of different concentrations of microplastics on physiological indices and metabolites of highland barley were investigated for the first time using a metabolomics approach, and revealed the response mechanism of barley seedlings to polystyrene microplastics (PS-MPs) was revealed. The results showed that the aboveground biomass of highland barley exposed to low (10 mg/L) and medium (50 mg/L) concentrations of PS-MPs increased by 32.

Advanced atherosclerosis is the pathological basis for acute cardiovascular events, with significant residual risk of recurrent clinical events despite contemporary treatment. The death of foamy macrophages is a main contributor to plaque progression, but the underlying mechanisms remain unclear. Bulk and single-cell RNA sequencing demonstrated that massive iron accumulation in advanced atherosclerosis promoted foamy macrophage ferroptosis, particularly in low expression of triggering receptor expressed on myeloid cells 2 (TREM2) foamy macrophages.

Pyrosomes represent a group of marine holozooplankton. They do not exist as individual entities but as intricate colonies comprising numerous zooids, well-known for their bioluminescent properties. Pyrosomes inhabit most oceanic waters spanning tropical to temperate regions.

Photoelectrochemical (PEC) biosensing, recognized for its heightened sensitivity, faces limitations in its application for diagnosis due to the inefficiency of UV-visible light-driven photoactive materials in nontransparent biological samples. In this study, we investigate the potential of an S-scheme all-polymer heterojunction comprising a prototype nonfullerene polymeric acceptor (PYIT) and carbon nitride to develop a near-infrared (NIR) light-driven PEC biosensor for monitoring acetylcholinesterase activity in nontransparent human whole blood. The distinct molecular structure of PYIT enables efficient light absorption in the NIR region, enhancing sensitivity in nontransparent biological samples.

Objectives: Imipenem/cilastatin/relebactam (IMI/REL) is a β-lactam/β-lactamase inhibitor combination effective against gram-negative pathogens. Efficacy and safety of IMI/REL were studied in critically ill adults with hospital-acquired bacterial pneumonia (HABP) or ventilator-associated bacterial pneumonia (VABP).

Methods: In this phase III, double-blind, multinational, randomized trial (NCT03583333), adults with HABP/VABP were randomized 1:1 to receive intravenous IMI/REL (500 mg/250 mg) or piperacillin/tazobactam (PIP/TAZ; 4000 mg/500 mg) every 6 h for 7-14 days.

Although semantic segmentation is widely employed in autonomous driving, its performance in segmenting road surfaces falls short in complex traffic environments. This study proposes a frequency-based semantic segmentation with a transformer (FSSFormer) based on the sensitivity of semantic segmentation to frequency information. Specifically, we propose a weight-sharing factorized attention to select important frequency features that can improve the segmentation performance of overlapping targets.

Purpose: To compare the diagnostic value of [F]ALF-NOTA-FAPI-04 positron emission tomography/computed tomography (PET/CT) and F-fluorodeoxyglucose (FDG) PET/CT in gastric cancer.

Methods: This single-center retrospective analysis included 65 patients with gastric cancer who received both [F]FDG and [F]ALF-NOTA-FAPI-04 PET/CT for initial staging or restaging. Histopathological manifestations, typical imaging manifestations, follow-up imaging, and comprehensive clinical assessment were used as reference criteria.

  • Ustekinumab (UST) is the recommended first-line treatment for moderate to severe Crohn's disease (CD), but not all patients respond well, necessitating a way to predict treatment effectiveness.
  • Researchers created a nomogram model using data from patients treated with UST to forecast short-term effectiveness by analyzing various clinical and demographic factors.
  • The study included 162 patients and identified key predictors like BMI, smoking, and previous treatments, showing the model had good predictive accuracy with a C-index of 0.843, indicating its potential clinical utility.

Background: The optimal duration of dual antiplatelet therapy (DAPT) for patients with coronary multi-vessel disease (MVD) who have received drug-eluting stents (DES) remains unclear.

Hypothesis And Methods: The Dual Antiplatelet Therapy in Patients with Coronary Multi-Vessel Disease (DAPT-MVD) study is a multicenter, open-label, randomized controlled trial designed to assess the efficacy and safety of extended DAPT in MVD patients 12 months following DES implantation. We plan to enroll 8250 patients across approximately 100 sites in China.

Biostimulators have been increasingly popular for facial rejuvenation in recent years. Among them, Sculptra (based on poly-L-lactic acid (PLLA)) and AestheFill (based on poly-D,L-lactic acid (PDLLA)) are supplied as lyophilized powders in vials. Both need to be reconstituted with sterile water into homogeneous suspensions before injection.

Article Synopsis
  • The study investigates coronary artery calcification (CAC) as a significant indicator of atherosclerosis and its link to clinical outcomes, highlighting the need for better imaging analysis methods.* -
  • Researchers developed a deep learning technique to automatically identify and measure CAC using a large dataset of over 1 million OCT images from 1,048 patients, achieving nearly human-level accuracy in their assessments.* -
  • Analysis of 1,259 patients with ST-segment elevated myocardial infarctions showed that those with more severe calcification in the affected arteries faced a higher risk of major cardiovascular and cerebrovascular events, while calcification in other arteries was not significantly linked to these risks.*

The detection of electric fields in the environment has great importance for understanding various natural phenomena, environmental monitoring, and ensuring human safety. This review paper provides an overview of the current state-of-the-art technologies utilized for sensing electric fields in the environment, the challenges encountered, and the diverse applications of this sensing technology. The technology is divided into three categories according to the differences in the physical mechanism: the electro-optic effect-based measurement system, the MEMS-based sensor, and the newly reported quantum effect-based sensors.

We propose and demonstrate a radio-frequency (rf) atomic magnetometer based on parametric resonances. Previously, most rf atomic magnetometers are based on magnetic resonances and their sensitivities are often limited by spin-exchange relaxation. Here, we introduce a novel scheme for an rf magnetometer where the rf magnetic field is measured by exciting the parametric resonances instead of magnetic resonances using parametric modulation fields.

Ion preintercalation is an effective method for fine-tuning the electrochemical characteristics of electrode materials, thereby enhancing the performance of aqueous ammonium-ion hybrid supercapacitors (A-HSCs). However, much of the current research on ion preintercalation lacks controllability, and the underlying mechanisms remain unclear. In this study, we employ a two-step electrochemical activation approach, involving galvanostatic charge-discharge and cyclic voltammetry, to modulate the preintercalation of NH in MnO.

Background: Hypertension management apps (HMAs) can be effective in controlling blood pressure, but their actual impact is often suboptimal. Establishing a user satisfaction evaluation indicator system for HMAs can assist app developers in enhancing app design and functionality, while also helping users identify apps that best meet their needs. This approach aims to improve the overall effectiveness of app usage.

Ferroptosis is a predominant contributor to graft kidney ischemia‒reperfusion injury (IRI), resulting in delayed graft function (DGF). However, much less is known about the early predicting biomarkers and therapeutic targets of DGF, especially aiming at ferroptosis. Here, we propose a precise predicting model for DGF, relying on the Akirin1 level in extracellular vesicles (EVs) derived from recipient urine 48 h after kidney transplant.
