2019, Molecular and Cellular EndocrinologyCitation Excerpt :Notably, the altered pattern of insulin response in BN may vary widely depending on behavioral symptoms of the disorder. Data collected throughout the process of binge eating and purging suggest that peripheral insulin levels tend to increase during binge episodes but precipitously decline following vomiting (Kaye et al., 1988). However, relative to healthy controls who ingest a large meal, individuals with BN show exaggerated insulin release for 3 h after binge eating and vomiting (Kaye et al., 1989).
Day-night behaviour and performance of barrows and gilts (70-100 kg) fed low protein diets with different levels of tryptophan and B6 vitamin
2016, Applied Animal Behaviour ScienceCitation Excerpt :Thus, dietary strategies regulating the relative availability of Trp to LNAA (Trp:LNAA) could give Trp an advantage for access to the brain and could increase the availability of Trp in the brain, thereby altering the concentration of hypothalamic 5-HT and, subsequently, behavioural responses (Markus et al., 2000; Verschoor et al., 2010). Some studies have shown that 20–40% changes in the ratio of Trp:LNAA could lead to higher serotonin concentrations (Pérez-Cruet et al., 1974; Kaye et al., 1988), whereas others achieving only a 20–25% increase in the Trp:LNAA ratio observed limited changes in hypothalamic serotonin (Ashley et al., 1985; Lambert et al., 1995). In this study, the changes in Trp:LNAA ratio in diets for barrows and gilts ranged from 20 to 58% in relation to basal diet, but seemed not enough to affect pigs behaviour as a consequence of higher synthesis of serotonin.
