Porphyria / p ɔːr ˈ f ɪr i ə / is a group of disorders in which substances called porphyrins build up in the body, adversely affecting the skin or nervous system. [1] The types that affect the nervous system are also known as acute porphyria , as symptoms are rapid in onset and short in duration. [ 1 ]
Variegate porphyria has an autosomal dominant pattern of inheritance. Mutations in the PPOX gene cause variegate porphyria. [4] The PPOX gene makes a membrane bound mitochondrial enzyme called protoporphyrinogen oxidase, which is critical to the chemical process that leads to heme production. The activity of this enzyme is reduced by 50 percent ...
PDT is considered a noninvasive cancer treatment, involving the interaction between light of a determined frequency, a photo-sensitizer, and oxygen. This interaction produces the formation of a highly reactive oxygen species (ROS), usually singlet oxygen, as well as superoxide anion, free hydroxyl radical, or hydrogen peroxide. [ 17 ]
Carcinogenic parasites are parasitic organisms that depend on other organisms (called hosts) for their survival, and cause cancer in such hosts.Three species of flukes are medically-proven carcinogenic parasites, namely the urinary blood fluke (Schistosoma haematobium), the Southeast Asian liver fluke (Opisthorchis viverrini) and the Chinese liver fluke (Clonorchis sinensis).
Porphyria cutanea tarda is the most common subtype of porphyria. [1] The disease is named because it is a porphyria that often presents with skin manifestations later in life. The disorder results from low levels of the enzyme responsible for the fifth step in heme production. Heme is a vital molecule for all of the body's organs.
Buckingham Palace says that some medical historians think that George III’s mental health condition was caused by a hereditary physical disorder called porphyria, which is a rare disorder that ...
The World Health Organization has identified glyphosate as "possibly carcinogenic to humans" and a study published earlier this year showed that glyphosate raised the cancer risk of those exposed ...
Hepatic porphyrias is a form of porphyria in which toxic porphyrin molecules build up in the liver. Hepatic porphyrias can result from a number of different enzyme deficiencies. [1] Examples include (in order of synthesis pathway): [citation needed] Acute intermittent porphyria; Porphyria cutanea tarda and Hepatoerythropoietic porphyria
