The connection between the gut mycobiome and atherosclerotic cardiovascular disease (ACVD) is largely uncharted. In our study, we compared the gut fungal communities of 214 ACVD patients with those of 171 healthy controls using shotgun metagenomic sequencing and examined their interactions with gut bacterial communities and network key taxa. The gut mycobiome composition in ACVD patients is significantly different, showing a rise in opportunistic pathogens like , , and , with and showing the most significant changes (Wilcoxon rank-sum test, < 0.

Objective: The lipid-lowering simvastatin (SIM) has been shown to be an effective inhibitor of keloid proliferation. However, due to its low water solubility and short half-life, simvastatin aggregates to the liver and does not reach the skin lesions after oral administration, which restricts its widespread clinical use. The development of nanomedicine provides the possibility for us to break through this bottleneck problem clinically.

  • Chronic myeloid leukaemia (CML) is primarily driven by the genetic abnormality BCR::ABL1, and the standard first-line treatment involves tyrosine kinase inhibitors (TKIs).
  • Various health organizations have set benchmarks to assess how well patients respond to initial TKI therapy and when to consider switching medications.
  • Achieving treatment-free remission (TFR) is now viewed as the ideal outcome, but debates continue over the best initial TKI choice and the required depth and duration of molecular remission for TFR success.

Article Synopsis
  • - The study aimed to investigate congenital dysfibrinogenemia (CD) in a Chinese family by assessing coagulation deficits and genetic causes.
  • - Blood tests revealed reduced fibrinogen activity in the proband and her father, while other family members showed normal results; two genetic variants were found in the FGA and FGG genes, with one variant likely linked to the condition.
  • - The inheritance pattern of CD in this family was determined to be autosomal dominant, indicating that the newly identified variant in the FGG gene may play a significant role in the development of the disorder.

Head and neck squamous cell carcinoma (HNSC) is the most common malignant tumor that arises in the epithelium of the head and neck regions. Myeloid-derived suppressor cells (MDSCs) are one of the tumor-infiltrating immune cell populations, which play a powerful role in inhibiting anti-tumor immune response. Herein, we employed a single-cell RNA sequencing (scRNA-seq) dataset to dissect the heterogeneity of myeloid cells.

Article Synopsis
  • Alzheimer's disease (AD) is a neurodegenerative disorder where the role of lncRNA RMRP has mainly been studied in cancer, but its function in AD is unclear.
  • The study used human serum samples, AD transgenic mice, and SH-SY5Y cells to assess the expressions of RMRP, miR-3142, and TRIB3, and examined their roles in apoptosis and autophagy.
  • Results showed that knocking down RMRP reduced neuron death and autophagy, and RMRP appears to promote TRIB3 levels by sponging miR-3142, indicating that targeting RMRP could be a potential treatment for AD.
