Abstract Hydrogels have shown great potential and value in wound healing.In this study, we construct a mesenchymal stem cell exosomes (MSC-Exos) laden natural biopolymer-based hydrogel with transparent, self-healing, injectable, and tissue adhesive properties to promote corneal regeneration.This hydrogel is synthesized by combining aldehyde-modifie
Background Stomach pain is an ailment that occurs frequently in the general population.It is not unusual if such stomach issues produce some amount of stress in an individual, but it can be worrying if these pains lead to significant mental health problems.The relationship between some abdominal pain, such as bowel syndrome, and depression or anxie
Abstract Background We provide an overview of Bayesian estimation, hypothesis testing, and model-averaging and illustrate how they benefit parametric survival analysis.We contrast the Bayesian framework to the currently dominant frequentist approach and highlight advantages, such as seamless incorporation of historical data, continuous monitoring o
