5-Methylcytosine (m5C) is a ubiquitous RNA modification that is closely related to various cellular functions. However, no studies have comprehensively demonstrated the role of m5C in hepatocellular carcinoma (HCC) progression. In this study, six pairs of HCC and adjacent tissue samples were subjected to methylated RNA immunoprecipitation sequencing to identify precise m5C loci.

Paradigm Transformation of Global Health Data Regulation: Challenges in Governance and Human Rights Protection of Cross-Border Data Flows.

The growing global exchange of healthcare data requires more cohesive and effective regulatory frameworks to ensure fair access and protect patient privacy. However, cross-border regulatory rules for healthcare data diverge across countries, such as the EU, which highlights personal data rights and restricts cross-border flow of healthcare data through the GDPR, the United States, which emphasizes the free flow of healthcare data trade or services, and China, which emphasizes cross-border regulatory rules for healthcare data at the level of national data security. Such inconsistent policies often impede international medical research collaborations, undermine the effectiveness of telemedicine, and create barriers for healthcare providers to share patient information.

Multibranch semantic image segmentation model based on edge optimization and category perception.

In semantic image segmentation tasks, most methods fail to fully use the characteristics of different scales and levels but rather directly perform upsampling. This may cause some effective information to be mistaken for redundant information and discarded, which in turn causes object segmentation confusion. As a convolutional layer deepens, the loss of spatial detail information makes the segmentation effect achieved at the object boundary insufficiently accurate.

Role of clinicopathologic and sonographic characteristics for the management of patients with cytological diagnosis of thyroid follicular neoplasm.

Background: Thyroid cancer is one of the most common endocrine tumors and preoperative diagnosis of thyroid follicular neoplasm (FN) is challenging. Commonly used examination methods have difficulty in distinguishing thyroid cancer from other follicular lesions. At the same time, with the recently released World Health Organization (WHO) guidelines, the risk classification of FNs of the thyroid is a new enlightenment for clinicians in the diagnosis and treatment.

Visualization of Unconjugated Bilirubin In Vivo with a Novel Approach Using Chemical Exchange Saturation Transfer Magnetic Resonance Imaging in a Rat Model.

Unconjugated bilirubin (UCB) visualization is valuable for early bilirubin encephalopathy (BE) diagnosis and management. UCB neurotoxicity is a challenge, necessitating improved imaging modalities for precise localization and characterization. This study developed a noninvasive method for UCB imaging in the brain using chemical exchange saturation transfer (CEST) magnetic resonance imaging, which visualizes UCB distribution through amide-bulk water proton exchange, a process termed bilirubin CEST (Bil-CEST) imaging.

Rotenone adaptation promotes migration and invasion of p53-wild-type colon cancer through lipid metabolism.

Background: The association between mitochondrial dysfunction and multiple metabolic adaptations is increasingly being proven. We previously elucidated that mitochondrial complex I deficiency can promote glycolysis in mut-p53 SW480 cells. However, studies have revealed a phenotype with attenuated glycolysis but enhanced fatty acid oxidation (FAO) in invasive tumors.

Proteomic Analysis of Tissue Proteins Related to Lateral Lymph Node Metastasis in Papillary Thyroid Microcarcinoma.

Patients with lateral lymph node metastasis (LLNM) may experience higher locoregional recurrence rates and poorer prognoses compared to those without LLNM, highlighting the need for effective preoperative stratification to reliably assess risk LLNM. In this study, we collected PTMC samples from Peking Union Medical College Hospital and employed data-independent acquisition mass spectrometry proteomics technique to identify protein profiles in PTMC tissues with and without LLNM. Pseudo temporal analysis and single sample gene set enrichment analysis were conducted in combination with The Cancer Genome Atlas Thyroid Carcinoma for functional coordination analysis and the construction of a prediction model based on random forest.

Finally, three pairs of enantiomeric isoquinoline alkaloids (, including five undescribed compounds-, and ), together with another eight known isoquinoline alkaloids () were isolated from the roots and rhizomes of .

Serum small extracellular vesicles-derived BST2 as a biomarker for papillary thyroid microcarcinoma promotes lymph node metastasis.

Papillary thyroid microcarcinoma (PTMC), although frequently indolent, could be aggressive in a few patients, leading to lymph node metastasis (LNM) and worsened prognosis. To explore the role of protein profiling of small extracellular vesicles (sEVs) in the auxiliary diagnosis and risk stratification of PTMC, proteins in serum sEVs isolated from PTMC patients with (N = 10) and without (N = 10) LNM and benign thyroid nodule (BN) patients (N = 9) were profiled via a bioinformatics-integrated data-independent acquisition proteomic technique. The performance of candidate proteins as diagnostic and prognostic biomarkers in PTMC was assessed via receiver operating characteristic analysis.

Multimodal integrated flexible neural probe for monitoring of EEG and lactic acid.

In physiological activities, the brain's electroencephalogram (EEG) signal and chemical concentration change are crucial for diagnosing and treating neurological disorders. Despite the advantages of flexible neural probes, such as their flexibility and biocompatibility, it remains a challenge to achieve monitoring of electrophysiological and chemical signals on a small scale simultaneously. This study developed a new method to construct an efficient dual-sided multimodal integrated flexible neural probe, which combines a density electrode array for EEG recordings and an electrochemical sensor for detecting lactic acid.

An ultrasensitive multimodal intracranial pressure biotelemetric system enabled by exceptional point and iontronics.

The accurate monitoring of vital physiological parameters, exemplified by heart rate, respiratory rate, and intracranial pressure (ICP), is of paramount importance, particularly for managing severe cranial injuries. Despite the rapid development of implantable ICP sensing systems over the past decades, they still suffer from, for example, wire connection, low sensitivity, poor resolution, and the inability to monitor multiple variables simultaneously. Here, we propose an ultrasensitive multimodal biotelemetric system that amalgamates an iontronic pressure transducer with exceptional point (EP) operation for the monitoring of ICP signals.

Citrus Fruits Produce Direct Defense Responses against Oviposition by (Diptera: Tephritidae).

Plants perceive and orchestrate defense responses when herbivorous insects are ovipositing. Fruits, as a crucial reproductive organ in plants, have rarely been researched on the responses to insect eggs. Here, we found that oviposition by the specialist insect in navel oranges activated the lignin synthesis pathway and cell division, causing mechanical pressure that crushed the eggs.

Two-stage mural image restoration using an edge-constrained attention mechanism.

The current mainstream image restoration methods have difficulty fully learning the structure and color information of murals in mural image restoration tasks due to the limited size of the available datasets, resulting in problems such as structural loss and texture errors. This study proposes a two-stage mural restoration network based on an edge-constrained attention mechanism. This paper introduces additional sketches as inputs during the coarse restoration phase and incorporates a local edge loss function to enable the network to generate corresponding structural information based on the sketches.

Polyphest: fast polyploid phylogeny estimation.

Motivation: Despite the widespread occurrence of polyploids across the Tree of Life, especially in the plant kingdom, very few computational methods have been developed to handle the specific complexities introduced by polyploids in phylogeny estimation. Furthermore, methods that are designed to account for polyploidy often disregard incomplete lineage sorting (ILS), a major source of heterogeneous gene histories, or are computationally very demanding. Therefore, there is a great need for efficient and robust methods to accurately reconstruct polyploid phylogenies.

Firmicutes primarily drive odor emission profiles in poultry manure treatments.

Odor emission during livestock manure treatment poses a threat to the environment and human health. However, the odor emission profiles and related factors of commonly employed poultry manure treatments have rarely been studied. Here, we explored the odor emission profiles of 3 common poultry manure treatments in China, namely, ectopic fermentation beds (EFB), annular composting troughs (ACT) and air-drying rooms (ADR).

Exploring serum -glycome patterns as candidate non-invasive biomarkers in inguinal hernia.

Introduction: Although inguinal hernia (IH) is prevalent in elderly males, research on its specific diagnostic biomarkers is limited. Protein -glycosylation is one of the most important and ubiquitous post-translational modifications and often results in a remarkable heterogeneity of protein glycoforms. Protein -glycosylation often changes in a disease and holds great potential for discovering non-invasive biomarkers.
