Neonatal high-dose riboflavin treatment channels energy expenditure towards sensorimotor and somatic development and reduces rodent growth and weight gain by modulating NRF-1 in the hypothalamus.

Metabolic adaptations early in life can drive energy expenditure towards brain and physical development, with less emphasis on body mass gain and somatic growth. Dietary or pharmacological manipulations can influence these processes, but to date, the effects provided by riboflavin have not been studied. The study aimed to evaluate the effects of neonatal treatment with different doses of riboflavin on sensorimotor and somatic development in rodents.

Effects of deficiency or supplementation of riboflavin on energy metabolism: a systematic review with preclinical studies.

Context: Riboflavin (vitamin B2) is a water-soluble micronutrient considered to be a precursor of the nucleotides flavin adenine dinucleotide and flavin mononucleotide. This vitamin makes up mitochondrial complexes and participates as an enzymatic cofactor in several mechanisms associated with energy metabolism.

Objective: This systematic review collected and discussed the most relevant results on the role of riboflavin in the energy metabolism of lipids, proteins, and carbohydrates.

Neonatal kaempferol exposure attenuates impact of cerebral palsy model on neuromotor development, cell proliferation, microglia activation, and antioxidant enzyme expression in the hippocampus of rats.

Objectives: This study aims to assess the effect of neonatal treatment with kaempferol on neuromotor development, proliferation of neural precursor cells, the microglia profile, and antioxidant enzyme gene expression in the hippocampus.

Methods: A rat model of cerebral palsy was established using perinatal anoxia and sensorimotor restriction of hindlimbs during infancy. Kaempferol (1 mg/ kg) was intraperitoneally administered during the neonatal period.
