Lichen planus is a chronic recurrent rash that is due to inflammation in the skin and mucous membranes. The rash is characterized by small, flat-topped, many-sided (polygonal) bumps that can grow together into rough, scaly plaques on the skin.
Brodifacoum is a highly lethal 4-hydroxycoumarin vitamin K antagonist anticoagulant poison. In recent years, it has become one of the world's most widely used pesticides. It is typically used as a rodenticide but is also used to control larger pests such as possum.ompound 1 is the starting ester needed to synthesize brodifacoum. To obtain this starting compound a simple Wittig condensation of ethyl chloroacetate with 4â-bromobiphenylcarboxaldehyde was accomplished.
Gadolinium is a silvery-white malleable and ductile rare-earth metal. It crystallizes in hexagonal, close-packed Î±-form at room temperature, but, when heated to temperatures above 1235 Â°C, it transforms into its Î²-form, which has a body-centered cubic structure.adolinium as a phosphor is also used in other imaging. In X-ray systems, gadolinium is contained in the phosphor layer, suspended in a polymer matrix at the detector. Terbium-doped gadolinium oxysulfide (Gd 2 O 2 S: Tb) at the phosphor layer converts the X-rays released from the source into light.
