Liquid oxygen is the name of a product that is a solution of hydrogen peroxide [1] and other compounds including sodium chloride (common salt) [2] [3] that claims to help with "jet lag, fatigue, altitude sickness, headaches, hangovers, youthful skin, energy, and insomnia".
Human herpes virus One of the most notable functions of this virus family is their ability to enter a latent phase and lay dormant within animals for extended periods of time. [ 1 ] The mechanism that controls this is very complex because expression of viral proteins during latency is decreased a great deal, meaning that the virus must have ...
Lytic infection is sometimes known as "productive" infection. Latent cells harbor the virus for long time periods, then occasionally convert to productive infection which may lead to a recurrence of symptomatic Herpes symptoms. During latency, most of the Herpes DNA is inactive, with the exception of LAT, which accumulates within infected cells.
While primary infection is often accompanied by a self-limited period of clinical illness, long-term latency is symptom-free. [citation needed] Chromatin dynamics regulate the transcription competency of entire herpes virus genomes. When the virus enters a cell, the cellular immune response is to protect the cell.
One example is the herpes virus family, Herpesviridae, all of which establish latent infection. Herpes virus include chicken-pox virus and herpes simplex viruses (HSV-1, HSV-2), all of which establish episomal latency in neurons and leave linear genetic material floating in the cytoplasm. [3]
Herpes virus DNA contains a gene for a protein called ICP4, which is an important transactivator of genes associated with lytic infection in HSV-1. [47] Elements surrounding the gene for ICP4 bind a protein known as the human neuronal protein neuronal restrictive silencing factor (NRSF) or human repressor element silencing transcription factor ...
Herpes simplex, often known simply as herpes, is a viral infection caused by the herpes simplex virus. [5] Herpes infections are categorized by the area of the body that is infected. The two major types of herpes are oral herpes and genital herpes , though other forms also exist.
A viral infection does not always cause disease. A viral infection simply involves viral replication in the host, but disease is the damage caused by viral multiplication. [5] An individual who has a viral infection but does not display disease symptoms is known as a carrier. [17] Mechanisms by which viruses cause damage and disease to host cells
