G2‐PASE: A Novel, Rapid, and Reliable Measure of Plaque Psoriasis Severity

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Background The Psoriasis Area and Severity Index (PASI), a composite measure of plaque psoriasis disease severity, is commonly used to determine treatment eligibility and response, but is time consuming for every‐day clinical use. The Gulliver‐Gestalt‐Psoriasis Area Severity Estimate (G2‐PASE) was developed to approximate PASI scores using ...

Atmospheric Chemistry of CFH2CH2CH2CFH2: Kinetics and Mechanism of Reactions With Cl Atoms and OH Radicals

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT The atmospheric chemistry of 1,4‐difluorobutane (CFH2CH2CH2CFH2) was investigated through a kinetic and mechanistic study of the reaction with chlorine (Cl) atoms and hydroxyl (OH) radicals. Using Fourier transform infrared (FTIR) spectroscopy and relative rate methods, the rate constants (k) for the reactions were determined at 298 ± 2 K as k(
