Genomewide meta-analysis identifies loci associated with IGF-I and IGFBP-3 levels with impact on age-related traits

The growth hormone/insulin-like growth factor (IGF) axis can be manipulated in animal models to promote longevity, and IGF-related proteins including IGF-I and IGF-binding protein-3 (IGFBP-3) have also been implicated in risk of human diseases including cardiovascular diseases, diabetes, and cancer.

Soil Dynamic Models: Predicting the Behavior of Fertilizers in the Soil

This chapter provides an overview of the most dominant processes for the situation where organic biobased derivatives are added to the soil, with emphasis on decomposition, production of mineral nutrients, and losses to the environment. Organic compounds in the soil (organic matter, organic fertilizers, biobased derivatives, soil biomass) are subject to microbiological conversion reaction. Decomposition of organic matter usually occurs relatively quickly as long as enough molecular oxygen is present. Two major models can be distinguished in modeling mineralization of organic matter: multi‐pool models with a constant decomposition rate factor and models with a time‐dependent decomposition rate factor. Leaching is the loss of nutrients via draining of water as a result of excess rainfall or irrigation. It is of environmental concern as it contributes to the contamination of the groundwater and surface‐water systems. The chapter presents an overview of processes for some selected soil dynamic models.<br/
