Amiodarone

Amiodarone is an antiarrhythmic medication used to treat and prevent a number of types of irregular heartbeats.

Bergapten

Bergapten (5-methoxypsoralen) is a psoralen (also known as furocoumarins) found in bergamot essential oil, in other citrus essential oils, and in grapefruit juice along with various other plants like figs and parsley.

Bovinae

The biological subfamily Bovinae includes a diverse group of 10 genera of medium to large-sized ungulates, including domestic cattle, bison, African buffalo, the water buffalo, the yak, and the four-horned and spiral-horned antelopes.

Buckwheat

Buckwheat (Fagopyrum esculentum), also known as common buckwheat, Japanese buckwheat and silverhull buckwheat, is a plant cultivated for its grain-like seeds and as a cover crop.

Chlorophyll

Chlorophyll (also chlorophyl) is any of several related green pigments found in cyanobacteria and the chloroplasts of algae and plants.

Heliotropism

Heliotropism, a form of tropism, is the diurnal motion or seasonal motion of plant parts (flowers or leaves) in response to the direction of the sun.

Hypericin

Hypericin is a naphthodianthrone, an anthraquinone derivative which, together with hyperforin, is one of the principal active constituents of Hypericum (Saint John's wort).

Hypericum perforatum

Hypericum perforatum, known as perforate St John's-wort, common Saint John's wort and St John's wort, is a flowering plant in the family Hypericaceae.

Intrinsically photosensitive retinal ganglion cells

Intrinsically photosensitive retinal ganglion cells (ipRGCs), also called photosensitive retinal ganglion cells (pRGC), or melanopsin-containing retinal ganglion cells (mRGCs), are a type of neuron in the retina of the mammalian eye.

Light

Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum.

New!!: Photosensitivity and Light · See more »

Photodermatitis

Photodermatitis, sometimes referred to as sun poisoning or photoallergy, is a form of allergic contact dermatitis in which the allergen must be activated by light to sensitize the allergic response, and to cause a rash or other systemic effects on subsequent exposure.

Photokeratitis

Photokeratitis or ultraviolet keratitis is a painful eye condition caused by exposure of insufficiently protected eyes to the ultraviolet (UV) rays from either natural (e.g. intense sunlight) or artificial (e.g. the electric arc during welding) sources.

Photon

The photon is a type of elementary particle, the quantum of the electromagnetic field including electromagnetic radiation such as light, and the force carrier for the electromagnetic force (even when static via virtual particles).

Photophobia

Photophobia is a symptom of abnormal intolerance to visual perception of light.

New!!: Photosensitivity and Photophobia · See more »

Photoreceptor cell

A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction.

New!!: Photosensitivity and Photoreceptor cell · See more »

Phototoxicity

Phototoxicity, also called photoirritation, is a chemically induced skin irritation, requiring light, that does not involve the immune system.

New!!: Photosensitivity and Phototoxicity · See more »

Porphyria

Porphyria is a group of diseases in which substances called porphyrins build up, negatively affecting the skin or nervous system.

Sheep

Domestic sheep (Ovis aries) are quadrupedal, ruminant mammal typically kept as livestock.

New!!: Photosensitivity and Sheep · See more »

Skin

Skin is the soft outer tissue covering vertebrates.

New!!: Photosensitivity and Skin · See more »

Solar urticaria

Solar urticaria (SU) is a rare condition in which exposure to ultraviolet or UV radiation, or sometimes even visible light, induces a case of urticaria or hives that can appear in both covered and uncovered areas of the skin.

Sulfonamide (medicine)

Sulfonamide (also called sulphonamide, sulfa drugs or sulpha drugs) is the basis of several groups of drugs.

Sunburn

Sunburn is a form of radiation burn that affects living tissue, such as skin, that results from an overexposure to ultraviolet (UV) radiation, commonly from the sun.

New!!: Photosensitivity and Sunburn · See more »

Systemic lupus erythematosus

Systemic lupus erythematosus (SLE), also known simply as lupus, is an autoimmune disease in which the body's immune system mistakenly attacks healthy tissue in many parts of the body.

Tetracycline antibiotics

Tetracyclines are broad-spectrum antibiotics whose general usefulness has been reduced with the onset of antibiotic resistance.

New!!: Photosensitivity and Tetracycline antibiotics · See more »

Xeroderma pigmentosum

Xeroderma pigmentosum (XP) is a genetic disorder in which there is a decreased ability to repair DNA damage such as that caused by ultraviolet (UV) light.
