DSIP
Also known as: Delta Sleep-Inducing Peptide
DSIP is a nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) isolated in 1977 from the cerebral blood of rabbits during electrically induced sleep. Mechanism remains uncertain and the clinical evidence base is weak. Not FDA-approved — research use only.

Predicting Sanitation Behaviors: Comparison of Willingness to Pay Techniques for Sanitation Services in Urban Dhaka, Bangladesh
Improving urban sanitation requires understanding user preferences and willingness to pay (WTP) for sewer connections. This study evaluates WTP for sanitation attributes in low-income communities (LICs) of Dhaka, Bangladesh, comparing contingent valuation (CVM) and hedonic pricing (HPM) methods.
