This study used prescription data from four medical institutions in representative cities in Central, Western and Eastern China, focusing on changes in antibiotic use under the National Centralized Drug Procurement Policy (NCDP) and calculating the contribution of NCDP and non-NCDP varieties to the changes. In outpatient settings, NCDP policy had little impact on the antibiotic prescription rate. Changes in antibiotic utilization rates were predominantly driven by non-NCDP varieties, particularly newer-generation antibiotics with enhanced therapeutic profiles.

In high-throughput gene sequencing, the quality of sequencing images is critical for the accuracy of subsequent base calling. However, during practical sequencing processes, the time delay integration (TDI) camera's push-scan imaging often leads to significant degradation of image quality along the push-scan direction. Addressing the current limitations in TDI image restoration research for gene sequencing, this study establishes an imaging spectrum model of sequencing images based on MGI's ultra-high-throughput sequencer.

Background: While simultaneous splenectomy (SPX) is an option in selected cases of living donor liver transplantation (LDLT) to protect graft function, graft-to-spleen volume ratio (GSVR) may serve as a new determinant of SPX. A prospective validation study was conducted to test our institutional strategy of SPX based mainly on GSVR, which has been employed since 2019.

Methods: This prospective study enrolled 141 LDLT recipients from 2019 to 2024.

It is still unclear how polystyrene nanoplastics (Ps-NPs) go through plant cell, and its physiological consequence and molecular mechanisms. To address this issue, the seedlings of tartary buckwheat (Fagopyrum tataricum) were exposed to hydroponic solution with 100 mg/L fluorescent-labeled Ps-NPs (100-nm diameter) across 0-2-4-6-8 days. Laser confocal microscopy, scanning electron microscopy and transmission electron microscope illuminated that Ps-NPs can go through root cells and cause significant physiological responses with time.

In volume visualization, users can interactively explore the three-dimensional data by specifying color and opacity mappings in the transfer function (TF) or adjusting lighting parameters, facilitating meaningful interpretation of the underlying structure. However, rendering large-scale volumes demands powerful GPUs and high-speed memory access for real-time performance. While existing novel view synthesis (NVS) methods offer faster rendering speeds with lower hardware requirements, the visible parts of a reconstructed scene are fixed and constrained by preset TF settings, significantly limiting user exploration.

Transformer-based trackers have achieved promising success and become the dominant tracking paradigm because of their accuracy and efficiency. Despite the substantial progress, most of the existing approaches handle object tracking as a deterministic coordinate regression problem, while the target localization uncertainty has been largely overlooked, which hampers trackers' ability to maintain reliable target state prediction in challenging scenarios. To address this issue, we propose UncTrack, a novel uncertainty-aware transformer-based tracker that predicts the target localization uncertainty and incorporates this uncertainty information for accurate target state inference.

As important immune regulatory cells, whether innate lymphoid cells (ILCs) are involved in liver transplantation (LT) remains unclear. In a murine orthotopic LT model, we dissected roles of ILCs in liver ischemia-reperfusion injury (IRI). Wild-type (WT) grafts suffered significantly higher IRI in Rag2-γc double knockout (DKO) than Rag2 knockout (KO) recipients, in association with downregulation of group 1 ILCs genes, including interferon gamma.

Camouflaged object detection (COD) aims to identify the objects that seamlessly blend into the surrounding backgrounds. Due to the intrinsic similarity between the camouflaged objects and the background region, it is extremely challenging to precisely distinguish the camouflaged objects by existing approaches. In this paper, we propose a hierarchical graph interaction network termed HGINet for camouflaged object detection, which is capable of discovering imperceptible objects via effective graph interaction among the hierarchical tokenized features.

Passive design characteristics (PDC) play a pivotal role in reducing the energy burden on households without imposing additional financial constraints on project stakeholders. However, the scarcity of PDC data has posed a challenge in previous studies when assessing their energy-saving impact. To tackle this issue, this research introduces an innovative approach that combines deep learning-powered computer vision with machine learning techniques to examine the relationship between PDC and energy burden in residential buildings.

Imbalances in the redox state of the liver arise during metabolic processes, inflammatory injuries, and proliferative liver disorders. Acute exposure to intracellular reactive oxygen species (ROS) results from high levels of oxidative stress (OxS) that occur in response to hepatic ischemia/reperfusion injury (IRI) and metabolic diseases of the liver. Antisense oligonucleotides (ASOs) are an emerging class of gene expression modulators that target RNA molecules by Watson-Crick binding specificity, leading to RNA degradation, splicing modulation, and/or translation interference.

Although cold preservation remains the gold standard in organ transplantation, cold stress-induced cellular injury is a significant problem in clinical orthotopic liver transplantation (OLT). Because a recent study showed that cold stress activates ferroptosis, a form of regulated cell death, we investigated whether and how ferroptosis determines OLT outcomes in mice and humans. Treatment with ferroptosis inhibitor (ferrostatin-1) during cold preservation reduced lipid peroxidation (malondialdehyde; MDA), primarily in liver sinusoidal endothelial cells (LSECs), and alleviated ischemia/reperfusion injury in mouse OLT.

Article Synopsis
  • The study explored the occurrence and effects of hidden bacterial infections (occult bacteremia) in liver transplant recipients and their living donors.
  • The researchers found that a significant percentage of both recipients and donors had these infections both before and after the surgery, with certain bacteria identified as the main culprits.
  • While the infections didn’t seem to harm the donors after surgery, recipients with occult bacteremia experienced a higher rate of infections post-transplant, indicating a risk due to their weakened immune systems.

Sirtuin 1 (SIRT1) is a histone/protein deacetylase in the cellular response to inflammatory, metabolic, and oxidative stressors. We previously reported that myeloid SIRT1 regulates the inflamed liver's canonical pyroptosis cell death pathway. However, whether/how hepatocyte SIRT1 is engaged in programmed cell death in the cold-stressed liver remains uncertain.

Background & Aims: Carcinoembryonic antigen-related cell adhesion molecule 1 (CC1) acts through homophilic and heterophilic interactions with T cell immunoglobulin domain and mucin domain-containing protein 3 (TIM-3), which regulates innate immune activation in orthotopic liver transplantation (OLT). We investigated whether cluster of differentiation (CD) 4 T cell-dependent CC1-TIM-3 crosstalk may affect OLT outcomes in mice and humans.

Methods: Wild-type (WT) and CC1-deficient (CC1 knock-out [KO]) mouse livers were transplanted into WT, CC1KO, or T-cell TIM-3 transgenic (TIM-3Tg)/CC1KO double-mutant recipients.
