Witryna11 kwi 2024 · Background: Insulin resistance (IR) is a major contributing factor to the pathogenesis of metabolic syndrome and type 2 diabetes mellitus (T2D). Adipocyte metabolism is known to play a crucial role in IR. Therefore, the aims of this study were to identify metabolism-related proteins that could be used as potential biomarkers of IR … WitrynaIn logistic population growth, the population's growth rate slows as it approaches carrying capacity. A population's carrying capacity is influenced by density-dependent and independent limiting factors. The equation for logistic population growth is written as (K-N/K)N. Logistic population growth produces an "S-shaped" curve when … WitrynaTwo new models, based upon the principles promulgated by Baranyi and co-workers are presented and resulting growth functions evaluated based upon their ability to mimic bacterial growth of the fish pathogen Flavobacterium psychrophilum.
