Overview Of Glp-1ra Medications, Thomas A.F. Cordaro Pharmd, Sumaiya A. Difaa Pharmd, Amel J. Basil Pharmd

Transformative Medicine

GLP-1 is an incretin hormone that is naturally produced in the body that regulates blood glucose and appetite. The first GLP-1RA that was FDA approved, exenatide, in 2005, originated from the Gila monster and beaded lizard, via the discovery of the exendin-4 peptide. GLP-1RAs function by mimicking endogenous GLP-1 incretin hormone, leading to an increase in glucose-dependent insulin release from beta-cells of the pancreas, decrease in glucagon release, delayed gastric emptying, and satiety. Due to the benefits seen from initiating GLP-1RAs in the market, it sparked interest in numerous studies which proved that certain GLP-1RAs can provide cardiorenal protection. The …

Unraveling The Connectedness Between Non-Fungible Tokens, Decentralized Finance, And Green Assets During Turbulent Times, Rija Anwar, Syed Ali Raza

Business Review

Green assets during the Bitcoin plummet-2018, COVID-2019, worldwide decline in oil demand-2020, and the Russia-Ukraine Conflict. The quantile connectedness approach, combined with the extreme tail of distribution technique (Ando et al., 2021), has been employed. According to static quantile connectedness, NFTs and DeFi assets perform the role of spillover transmitters; in contrast, green assets receive spillovers across three distinctive market settings. Additionally, the dynamic time-varying net directional connectedness estimates reveal that during normal market condition, the connectedness degree between NFTs, DeFi assets, and green assets remains low relative to extreme events at different point in time. Moreover, it provides valuable …
