The purpose of this study was to understand the impact altered polyamine levels on epidermal pigmentation. We used laser-capture microscopy and human primary melanocyte culture establish mechanisms by which polyamines function significance their misregulation in Melasma. are ubiquitously expressed cations that essential for a wide array cellular events. Changes intracellular can have regulatory...

Fires and explosions continue to be among the greatest threats to the safety of personnel and the survivability of military aircraft, ships, and land vehicles in peacetime and during combat operations. For these, halon 1301 (CF 3 Br) had been the fire suppressant of choice. However, production of halon 1301 was banned as of January 1, 1994 due to its high ozone-depleting potential (ODP). The Do...

Near infrared tunable diode laser (NE-TDL) spectroscopy is used to quantify HF gas produced during fire suppressant testing of halon alternatives. Results of comparisons with other techniques for measuring HF gas concentrations are discussed. Measurements of HF gas produced in laboratory and real-scale fire suppression testing are presented. The necessity for time-resolved measurements during t...

Most proposed replacements for Halon 1301 as a fire suppressant are halogenated hydrocarbons. The acute toxic endpoint of concern for these agents is cardiac sensitization. An approach is described that links the cardiac endpoint as assessed in dogs to a target arterial concentration in humans. Linkage was made using a physiologically based pharmacokinetic (PBPK) model. Monte Carlo simulations,...
