The renormalization group plays an essential role in many areas of physics, both conceptually and as a practical tool to determine the long-distance low-energy properties systems on one hand other search for viable ultraviolet completions fundamental physics. It provides us with natural framework study theoretical models where degrees freedom are correlated over long distances that may exhibit ...

background: effects of platelet-derived growth factor b (pdgf-b) on peripheral nerve regeneration was studied using a rat sciatic nerve transection model. materials and methods: forty‑five male, white wistar rats were divided into three experimental groups (n = 15), randomly: normal control group (nc), silicon group (sil), and pdgf‑b treated group (sil/pdgf). in nc group, left sciatic nerve was...

Background:HbA1c is an established diagnostic index which is used to assess diabetes mellitus. The aim of this study was to evaluate the association between HbA1c level with the types of stroke as well as the extent and functional status of ischemic stroke (IS) and hemorrhagic stroke (HS) in patients. Methods: In this cross-sectional study, we evaluated 120 pa...
