Cresyl violet stained partial brain section of a Macaque. It is used in biology and medicine as a histological stain. Cresyl violet is an effective and reliable stain used for light microscopy sections. Initially, tissue sections are "defatted" by passing through graded dilutions of ethanol. Then, rehydrated by passing back through decreasing ...
Crystal violet stains both Gram positive and Gram negative organisms. Treatment with alcohol removes the crystal violet colour from gram negative organisms only. Safranin as counterstain is used to colour the gram negative organisms that got decolorised by alcohol. While ex vivo, many cells continue to live and metabolize until they are "fixed".
Amyloid plaques are visible with the light microscope using a variety of staining techniques, including silver stains, Congo red, Thioflavin, cresyl violet, PAS-reaction, and luminescent conjugated oligothiophenes (LCOs).
In the few individual therapy sessions he received, staff used the time to go over rule violations, such as his misuse of his cell phone.

Photomicrograph of Nissl bodies (two are indicated by arrows) in the cytoplasm of motor neurons in the anterior horn of the spinal cord; cresyl violet stain (purple) along with a luxol fast blue stain for myelin. Scale bar = 30 microns (0.03mm). Drawing of a motor neuron from the ventral horn of the medulla spinals of a rabbit.
Blossom developed the school's program, calling it "Culture Shock Therapy" [7] or "Christian Milieu Therapy". According to former students of Escuela Caribe, they were subjected to a range of abuses including intense forced labor and repetitive exercise, physical beatings (called "swats"), extreme isolation, and various forms of emotional abuse.
Gram-positive cells have a thick layer of peptidoglycan in the cell wall that retains the primary stain, crystal violet. Gram-negative cells have a thinner peptidoglycan layer that allows the crystal violet to wash out on addition of ethanol. They are stained pink or red by the counterstain, [3] commonly safranin or fuchsine.
"A Series of Unfortunate Events" told the story of three young child whom become orphans after their parents are killed in a massive fire. They are then forced to go live with their very eccentric ...
