Objective: Referring all women who tested positive for human papillomavirus (HPV) 16/18 to colposcopy may lead to potential over-referral issues. Triage tests based on cytology results face challenges in achieving accurate diagnoses. Our study aims to assess the clinical effectiveness of PAX1/JAM3 methylation (CISCER) test as a triage method for HPV 16/18-positive women.

Understanding cerebrospinal fluid (CSF) dynamics is crucial for elucidating the pathogenesis and diagnosis of neurodegenerative diseases. The primary mechanisms driving CSF oscillations remain a topic of debate. This study investigates whether cerebral blood volume displacement (CBV), modulated by breathing and cardiac activity, are the predominant drivers of CSF oscillations.

Background: Hypertension or elevated blood pressure (BP) is a worldwide clinical challenge and the leading primary risk factor for kidney dysfunctions, heart failure, and cerebrovascular disease. The kidney is a central regulator of BP by maintaining sodium-water balance. Multiple genome-wide association studies revealed that BP is a heritable quantitative trait, modulated by several genetic, epigenetic, and environmental factors.

Article Synopsis
  • Microplastics (MPs), particularly conventional polystyrene (PS) and biodegradable polylactic acid (PLA), have been identified as significant contributors to the transfer of antibiotic resistance genes (ARGs) in wastewater treatment.
  • MPs enhance the conjugative transfer of ARGs during ultraviolet disinfection by providing light shielding and generating reactive oxygen species (ROS) that increase bacterial permeability.
  • The study emphasizes the environmental risks posed by both PS and PLA MPs in promoting ARG exchange, raising concerns about their impact on public health and wastewater treatment processes.

Heat pumps are an energy-efficient and increasingly cost-effective solution for reducing greenhouse gas emissions in the building sector. However, other clean energy technologies, such as rooftop solar, are less likely to be adopted in underserved communities, and thus policies incentivizing their adoption may funnel support to well-resourced communities. Unlike previously studied technologies, the effects of heat pumps on household energy bills may be positive or negative depending on local climate, energy costs, building features, and other factors.

Background And Purpose: Myasthenia gravis (MG) is characterized by fluctuating muscle weakness due to immune-mediated damage to acetylcholine receptors. Viral infections can exacerbate symptoms of muscle weakness, and the clinical status of patients with MG may influence the outcomes of such infections. Here, we identified factors of symptom exacerbation, severe SARS-CoV-2 infection, and pneumonia in patients with MG who are infected with SARS-CoV-2.

Background: Tetrandrine (TET) has multiple pharmacological activities, but its water solubility is poor, which is the main reason for its low bioavailability.

Objectives: The purpose of this study was to prepare TET nanocrystals (TET-NCs) using a grinding method to enhance the dissolution rate and ultimately improve the bioavailability of TET.

Methods: TET-NCs were synthesized via media milling, employing Poloxam 407 (P407) as surface stabilizer and mannitol as a cryoprotectant during freeze-drying.

Recently, research into the oncogenic driver genes associated with non-small cell lung cancer (NSCLC) has advanced significantly, leading to the development and clinical application of an increasing number of approved therapeutic agents. Among these, small molecule inhibitors that target mesenchymal-epithelial transition (MET) have demonstrated successful application in clinical settings. Currently, three categories of small molecule MET inhibitors, characterized by distinct binding patterns to the MET kinase region, have been developed: types Ia/Ib, II, and III.

Obstructive sleep apnea (OSA) is the most common type of sleep apnea, which leads to episodes of intermittent hypoxia due to obstruction of the upper airway. A key feature of OSA is the upregulation and stabilization of hypoxia-inducible factor 1 (HIF-1), a crucial metabolic regulator that facilitates rapid adaptation to changes in oxygen availability. Adenosine A2A receptor (A2AR), a major adenosine receptor, regulates HIF-1 under hypoxic conditions, exerting anti-inflammatory properties and affecting lipid metabolism.

Nanofluidics is a system of fluid transport limited to a nano-confined space, including the transport of ions and molecules. The use of intelligent nanofluidics has shown great potential in energy conversion. However, ion transport is hindered by homogeneous membranes with uniform charge distribution and concentration polarization, which often leads to an undesirable power conversion performance.

Schwann cells (SCs) are necessary for peripheral nerve regeneration due to their plasticity and trophic supply after sciatic nerve injury (SNI). However, the multiple adaptations of SCs are still poorly understood. This study explored the effects of transient axonal glycoprotein type-1 (TAG-1) on cell migration and neuropilin1 (NRP1) expression in SCs and examined the impact of TAG-1 on nerve regeneration in rats with SNI.

Background: Micronutrient research on Graves' disease (GD) is limited and controversial. Therefore, in order to explore possible correlations between genetically predicted amounts of six micronutrients [Copper (Cu), Iron (Ir), Zinc (Zn), Calcium (Ca), Vitamin C (VC), and Vitamin D (VD)] and GD risk, we carried out Mendelian randomization research (MR).

Methods: We conducted an MR analysis using genome-wide association studies (GWAS) from people of European ancestry and aggregated information from UK Biobank to provide insight into the relationships between micronutrients and GD.

Melanoma, a malignant skin tumor, presents significant treatment challenges, particularly in unresectable and metastatic cases. While immune checkpoint inhibitors (ICIs) targeting PD-1/PD-L1 have brought new hope, their efficacy is limited by low response rates and significant immune-mediated adverse events (irAEs). Through multi-omics data analysis, it is discovered that the spatial co-localization of CD73 and PD-L1 in melanoma correlates with improved progression-free survival (PFS), suggesting a synergistic potential of their inhibitors.

Carbon nanotubes (CNTs) show great promise for microwave absorption (MA) due to their excellent electrical conductivity and lightweight properties, which are conferred by the one dimensional hollow tubular structure. However, the ambiguous intrinsic motivations behind the formation of CNTs and the intricate growth processes have resulted in a lack of a systematic methodology for precisely controlling their electromagnetic properties. Herein, a flexible CNTs regulation strategy is designed to develop, with the core focus being the directional growth of carbon atoms and the differential catalysis of metal sources.
