Article Synopsis
  • Untargeted metabolomic analysis using mass spectrometry encounters challenges like complex data processing and high variability among samples, but a new method called DeepMSProfiler addresses these issues effectively.
  • DeepMSProfiler utilizes deep learning to analyze raw metabolic signals and differentiates between the profiles of lung adenocarcinoma, benign lung nodules, and healthy individuals with high accuracy (AUC 0.99).
  • The method not only detects early-stage lung adenocarcinoma with 96.1% accuracy but also provides insight into disease-related metabolite-protein networks and reveals important correlations in lipid metabolomic data, making it a valuable tool for disease diagnosis and research.

Background: Recently, JAKi has also been widely proved to be an effective alternative to conventional treatment for Synovitis acne pustulosis-hyperostosis-osteitis (SAPHO) cases, after failure of multiple drugs including those described above. But what to do when all these treatments fail? We report a case of remission from Tripterygium wilfordii Hook (TwHF) treatment.

Methods: The patient was treated with nonsteroidal anti-inflammatory drugs, oral prednisone, minocycline, bisphosphonate injection, etanercept, and tofacitinib, but the symptoms did not change significantly.

Background: Phosphorus in the soil is mostly too insoluble for plants to utilize, resulting in inhibited aboveground biomass, while can maintain their aboveground biomass through the presence of dauciform roots. However, dauciform roots lead to both morphological and physiological changes in the root system, making their primary mechanism unclear.

Methods: A greenhouse experiment was conducted on three species, in which Al-P, Ca-P, Fe-P, and K-P were employed as sole phosphorus sources.

Article Synopsis
  • The study focuses on understanding how new SARS-CoV-2 variants might contribute to long COVID and multi-organ injuries by examining the receptor interactions with the virus's spike protein.
  • Using multi-omic analysis, researchers found that the BSG (CD147) receptor has strong affinities with the delta and omicron variants, which could explain why these strains are more prevalent.
  • The findings suggest that BSG may play a significant role in the severity of COVID-19, especially in older individuals and those with pre-existing conditions, indicating potential targets for future vaccine and drug development.

Background: SARS-CoV-2, the agent responsible for the COVID-19 pandemic, enters cells through viral spike glycoprotein binding to the cellular receptor, angiotensin-converting enzyme 2 (ACE2). Given the lack of effective antivirals targeting SARS-CoV-2, we previously utilized systematic evolution of ligands by exponential enrichment (SELEX) and selected fluoro-arabino nucleic acid (FANA) aptamer R8-9 that was able to block the interaction between the viral receptor-binding domain and ACE2.

Methods: Here, we further assessed FANA-R8-9 as an entry inhibitor in contexts that recapitulate infection in vivo.

SARS-CoV-2 is primarily transmitted through droplets and airborne aerosols, and in order to prevent infection and reduce viral spread vaccines should elicit protective immunity in the airways. The neonatal Fc receptor (FcRn) transfers IgG across epithelial barriers and can enhance mucosal delivery of antigens. Here we explore FcRn-mediated respiratory delivery of SARS-CoV-2 spike (S).

Article Synopsis
  • The study presents the first constraint-based modeling of a single individual's gut microbiome affected by gastrointestinal inflammation, using extensive biomarker and fecal sample data over 16 months.
  • It identifies overproduction of more than 24 metabolites linked to inflammation, revealing shifts in microbial species and metabolic pathways during different phases of the condition.
  • The research concludes that changes in the gut microbiome can significantly affect overall metabolism and organ function, suggesting future studies could explore how diet and treatment influence these microbial dynamics.

Background: Dental pulp stem cells (DPSCs) play a crucial role in dentin-pulp complex regeneration. Further understanding of the mechanism by which DPSCs remain in a quiescent state could contribute to improvements in the dentin-pulp complex and dentinogenesis.

Methods: TSC1 conditional knockout (DMP1-Cre+; TSC1, hereafter CKO) mice were generated to increase the activity of mechanistic target of rapamycin complex 1 (mTORC1).

Given the concerns about climate change, energy sustainability, and public health, the reuse of kitchen wastes (KW) is attracting increasing interest. In China, the municipal solid waste sorting scheme has increased the available KW. To assess the available KW and the climate change mitigation potential of KW utilization for bioenergy in China, three scenarios (base, conservative, and ambitious) were defined.

SAPHO (synovitis, acne, pustulosis, hyperostosis, osteitis) syndrome is a rare disease characterized by osteoarticular and cutaneous manifestations. SAPHO syndrome mostly involves the skin, mainly presented as palmoplantar pustulosis and severe acne. Sweet's syndrome (SS) is a neutrophilic dermatosis of unknown cause, which may be caused by autoinflammation.

In this study, a numerical model of the plasma expansion on a droplet surface based on the initial plasma method was proposed. The initial plasma was obtained through the pressure inlet boundary condition, and the effect of ambient pressure on the initial plasma and adiabatic expansion of the plasma on the droplet surface, including the effect on the velocity and temperature distribution, were investigated. The simulation results showed that the ambient pressure decreased, leading to an increase in the expansion rate and temperature, and therefore a larger plasma size was formed.
