Pyroptosis is a type of programmed cell death that is mediated by both typical and atypical pathways and ultimately leads to the lysis and rupture of cell membranes and the release of proinflammatory factors, triggering an intense inflammatory response. Heart failure (HF) is a serious and terminal stage of various heart diseases. Myocardial hypertrophy, myocardial fibrosis, ventricular remodeling, oxidative stress, the inflammatory response and cardiomyocyte ionic disorders caused by various cardiac diseases are all risk factors for and aggravate HF.

Article Synopsis
  • The study explored the relationship between obstructive sleep apnea (OSA) and insulin resistance using data from the National Health and Nutrition Examination Survey, focusing on American adults aged 18 and older.
  • It used a generalized linear logistic regression model to assess how the triglyceride glucose index relates to OSA, considering various confounding factors.
  • Results showed that higher triglyceride glucose index levels were associated with an increased likelihood of having OSA, particularly in younger, male, white, and obese individuals.

Background: -mediated hairy root transformation provides a powerful tool for investigating the functions of plant genes involved in rhizobia-legume symbiosis. However, in the traditional identification methods of transgenic hairy roots based on reporter genes, an expensive chemical substrate or equipment is required.

Results: Here, we report a novel, low cost, and robust reporter for convenient, non-destructive, and directly visual selection of transgenic hairy roots by naked eye, which can be used in the study of rhizobia-legume symbiosis.
