Background And Aims: Inflammatory bowel diseases (IBDs) are chronic inflammatory conditions influenced heavily by environmental factors. DNA methylation is a form of epigenetic regulation linking environmental stimuli to gene expression changes and inflammation. Here, we investigated how DNA methylation of the tumor necrosis factor (TNF) promoter differs between inflamed and uninflamed mucosa of IBD patients, including anti-TNF responders and nonresponders.

Article Synopsis
  • The study aimed to measure changes in peak forces at the distal tibia, patellofemoral joint, and Achilles tendon during high-intensity runs until fatigue.
  • 16 experienced runners participated in the research, running on a treadmill at their maximum speed until failure, while their movements were analyzed in detail.
  • Results showed a decrease in tibial bending moments and Achilles tendon forces, but an increase in patellofemoral joint forces, suggesting potential risks for joint injuries without indicating similar risks for tibial or Achilles tendon injuries.

Article Synopsis
  • - Diamond-Blackfan anemia syndrome (DBA) is caused by mutations in over 20 ribosomal protein genes, and this study specifically investigates the role of RPL17, which encodes a large ribosomal subunit protein.
  • - Patients with RPL17 mutations exhibited typical DBA symptoms and erythroid proliferation defects, with further experiments showing that these mutations are pathogenic and lead to anemia in model organisms.
  • - The research found that RPL17 variants result in defects in ribosomal RNA maturation and suggest that DBA primarily stems from insufficient ribosome production rather than changes in ribosome structure, as indicated by altered translation profiles in cell lines.

How the neuromechanics of the lower limb functional muscle groups change with running speed remains to be fully elucidated, with implications for our understanding of human locomotion, conditioning, and injury prevention. This study compared the neuromechanics (ground reaction and joint kinetics, kinematics and muscle activity) of middle-distance athletes running on an instrumented treadmill at six wide-ranging speeds (2.78-8.
