Background: Fibroblast growth factor 21 (FGF-21) is a complex molecule involved in lipid and glucose metabolism. FGF-21 shares biochemical pathways and sites of action with thyroid hormones. Current data correlate FGF-21 levels to thyroid function. The aim of the present study was to investigate possible associations among FGF-21 levels, resting metabolic rate (RMR), lipidemic profile and L-thyroxin replacement therapy treatment in children and adolescents wit...

Objectives: Menarche is defined as the first menstrual bleeding in females, and the age of onset varies and depends on a complex interaction between genetic and environmental factors. The LIN28B gene single nucleotide polymorphisms (SNPs) rs314276, rs7759938 and rs314280 appear to be associated with cases of premature and early menarche. International databases report that the presence of a G allele of rs314280SNP shifts menarche 1.2 months earlier, a C allele...
