Background: Cell loss and mitochondrial dysfunction are key pathological features of idiopathic Parkinson's disease (PD) and multiple system atrophy (MSA). It remains unclear whether disease-specific changes in plasma circulating cell-free nuclear DNA (cf-nDNA) and mitochondrial DNA (cf-mtDNA) occur in patients with PD and MSA. In this study, we investigated whether plasma cf-nDNA, cf-mtDNA levels, as well as cf-mtDNA integrity, are altered in patients with PD and MSA.

A comprehensive immune landscape for infection is crucial for developing new treatments for brucellosis. Here, we utilized single-cell RNA sequencing (scRNA-seq) of 290,369 cells from 35 individuals, including 29 brucellosis patients from acute ( = 10), sub-acute ( = 9), and chronic ( = 10) phases as well as six healthy donors. Enzyme-linked immunosorbent assays were applied for validation within this cohort.

  • Researchers discovered that activating specific gene clusters (BGCs) in streptomycetes can lead to the production of new compounds, revealing many silent biosynthetic potential.* -
  • The study identified that two related genes, ovmZ and ovmW, are crucial for activating these silent BGCs, allowing the production of compounds like gephyromycin A when both genes are overexpressed in Streptomyces neyagawaensis.* -
  • The findings suggest that co-overexpression of ovmZ and ovmW could be a promising method for stimulating the production of secondary metabolites across various actinobacteria.*

  • This study investigates how variations in the CYP2D6 gene affect the response to angiotensin receptor blocker (ARB) treatment in hypertensive patients of the Chinese Bai ethnicity.
  • Seventy-two patients were genotyped for single nucleotide polymorphisms in CYP2D6, revealing nine significant variations that correlated with treatment effectiveness, particularly a mutation at rs111564371, which was linked to better blood pressure control.
  • Findings indicate that certain CYP2D6 polymorphisms can enhance ARB treatment outcomes by about 20%, contributing to a more personalized approach to healthcare in managing hypertension.

Background: Infections caused by linezolid-resistant enterococci (LRE) are clinically difficult to treat and threaten patient health. However, there is a lack of studies on long time-span LRE strains in China. For this reason, our study comprehensively revealed the resistance mechanisms of LRE strains collected in a Chinese tertiary care hospital from 2011 to 2022.

Identification of plasmids in bacterial genomes is critical for many factors, including horizontal gene transfer, antibiotic resistance genes, host-microbe interactions, cloning vectors, and industrial production. There are several methods to predict plasmid sequences in assembled genomes. However, existing methods have evident shortcomings, such as unbalance in sensitivity and specificity, dependency on species-specific models, and performance reduction in sequences shorter than 10 kb, which has limited their scope of applicability.
