Necrotising fasciitis in the elderly: comparison between patients aged 60 years and older and those younger than 60 years.

Introduction: Increasing age is associated with an increased incidence of necrotising fasciitis. In this study, we aimed to compare the clinical presentation, investigations, microbiology and clinical outcome in elderly (age ≥60 years) and nonelderly (age <60 years) patients with extremity necrotising fasciitis.

Methods: A retrospective review of patients with extremity necrotising fasciitis who were surgically treated between January 2005 and December 2021 was conducted.

sc-SPLASH provides ultra-efficient reference-free discovery in barcoded single-cell sequencing.

Typical high-throughput single-cell RNA-sequencing (scRNA-seq) analyses are primarily conducted by (pseudo)alignment, through the lens of annotated gene models, and aimed at detecting differential gene expression. This misses diversity generated by other mechanisms that diversify the transcriptome such as splicing and V(D)J recombination, and is blind to sequences missing from imperfect reference genomes. Here, we present sc-SPLASH, a highly efficient pipeline that extends our SPLASH framework for statistics-first, reference-free discovery to barcoded scRNA-seq (10x Chromium) and spatial transcriptomics (10x Visium); we also provide its optimized module for preprocessing and -mer counting in barcoded data, BKC, as a standalone tool.

DNA-damage orchestrates self-renewal and differentiation via reciprocal p53 family and Hippo/Wnt/TGF-β pathway activation in embryonic stem cells.

The mechanism by which DNA-damage affects self-renewal and pluripotency remains unclear. DNA damage and repair mechanisms have been largely elucidated in mutated cancer cells or simple eukaryotes, making valid interpretations on early development difficult. Here we show the impact of ionizing irradiation on the maintenance and early differentiation of mouse embryonic stem cells (ESCs).

Aberrant Cortical Morphological Networks in First-Episode Schizophrenia.

Background And Hypothesis: Population-based morphological covariance networks are widely reported to be altered in schizophrenia. Individualized morphological brain network approaches have emerged recently. We hypothesize that individualized morphological brain networks are disrupted in schizophrenia.
