An overview table of included studies is available in the Supplementary Material (S1) and online with options to filter the database ( The table includes information on first author and year of publication (1), paper title (2), whether the study was included in the meta-analysis (3) or systematic review (4), a tag indicating whether ghrelin or GLP-1 was investigated (5), specification of the hormonal assessment and/or manipulation (i.e., whether plasma acyl-, desacyl-, total ghrelin, GLP-1 was measured, which substance was administered (if any)) (6), type of reward phase assessed during fMRI (7), type of reward (e.g., food, money, alcohol) (8), and sample population(s) (9)
This is remarkable considering peptides have important shortcomings as they generally show poor membrane permeability, poor bioavailability, and short in vivo half-life
Topical corticosteroids should be applied in thin layers once daily, with potency ranging from Class VII (mild hydrocortisone 1%) to Class I (clobetasol 0.05%) for severe inflammation
There is evidence that nutrients might be able to modulate LTP via modulation of these receptors
It acts pro-angiogenically via VEGFR2: the peptide promotes VEGFR2 internalization and activates the VEGFR2-Akt-eNOS pathway, which is blocked by the endocytosis inhibitor Dynasore, and in preclinical models it increased vessel density as well as the restoration of blood flow in the ischemic rat hindlimb Hsieh et al., 2017
