This virus has been classified as Penaeus stylirostris hamaparvovirus. The genome is 4.1 kilobases in length. There are three open reading frames in its genome: [3] a left non structural protein (NS1) of 2001 base pairs (bp), a mid non structural protein (NS2) of 1092 bp and a right capsid protein of 990 bp. NSI appears to be a DNA helicase with ATPase activity.
Hormonal changes may be linked to causing perioral dermatitis. [16] Oral contraceptives (birth control pills) may also have a link as they significantly impact the hormonal balance of the people taking them. [16] Hormones are nature chemicals in the body that act as messengers by relaying information to different parts of the body.
Human herpesvirus 6 (HHV-6) is the common collective name for human betaherpesvirus 6A (HHV-6A) and human betaherpesvirus 6B (HHV-6B). These closely related viruses are two of the nine known herpesviruses that have humans as their primary host.
A hormone (from the Greek participle ὁρμῶν, "setting in motion") is a class of signaling molecules in multicellular organisms that are sent to distant organs or tissues by complex biological processes to regulate physiology and behavior. [1] Hormones are required for the correct development of animals, plants and fungi. Due to the broad ...
Helicobacter pylori, previously known as Campylobacter pylori, is a gram-negative, flagellated, helical bacterium.Mutants can have a rod or curved rod shape that exhibits less virulence.
Lastly, the "env" domain of the viral genome encodes for the glycoproteins and envelope on the surface of the virus. [1] [full citation needed] There are multiple steps involved in the infection and replication of a lentivirus in a host cell. In the first step the virus uses its surface glycoproteins for attachment to the outer surface of a cell.
White spot syndrome (WSS) is a viral infection of penaeid shrimp.The disease is highly lethal and contagious, killing shrimp quickly. Outbreaks of this disease have wiped out the entire populations of many shrimp farms within a few days, in places throughout the world.
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
