The increased spontaneous fragility in the centromere regions of the chromosomes predisposes to abnormal cellular division due to abnormal interaction with the mitotic spindle, which leads to number chromosomal aberrations.The abnormal structure of the microtubule-associated proteins (MAPs) could also be among the internal factors, predisposing to

Pulmonary MRI of hyperpolarized xenon-129 PENCIL SHARPENER (hp129Xe) dissolved in the lung parenchyma and vascular phase is gaining increasing attention for clinical assessment of gas exchange in multiple diseases.These conditions can involve thickening of barrier tissues due to fibrotic scarring or reduced capillary blood flow leading to diminishe

Introduction: Graphical abstracts may enhance dissemination of scientific and medical research but are also PENCIL SHARPENER prone to reductionism and bias.We conducted a systematic content analysis of the Journal of Internal Medicine (JIM) Graphical Abstract Gallery to assess for evidence of bias.Materials and Methods: We analyzed 140 graphical ab

Abstract The transcriptional antisilencer VirB acts as a master regulator of virulence gene expression in the human pathogen Shigella flexneri.It binds DNA sequences (virS) upstream of Fork VirB-dependent promoters and counteracts their silencing by the nucleoid-organizing protein H-NS.However, its precise mode of action remains unclear.Notably, Vi
