## 15-Hydroperoxy-5,8,11,13-eicosatetraenoic acid (15-HPETE)
15-HPETE is a **lipid peroxide**, specifically a **hydroperoxy eicosatetraenoic acid**, derived from the **arachidonic acid pathway**. It plays a crucial role in various physiological and pathological processes.
**Here's a breakdown:**
* **Arachidonic acid pathway:** This pathway is triggered by various stimuli, including inflammation, injury, and infection. It leads to the production of various bioactive lipid mediators, including prostaglandins, thromboxanes, leukotrienes, and lipoxins.
* **15-HPETE formation:** 15-HPETE is formed by the action of **15-lipoxygenase (15-LOX)**, an enzyme that catalyzes the oxygenation of arachidonic acid at the 15th carbon position.
* **Importance in research:** 15-HPETE is a **key intermediate** in the biosynthesis of other bioactive lipid mediators, particularly **lipoxins**. Lipoxins have anti-inflammatory properties and are involved in resolving inflammation. This makes 15-HPETE a crucial molecule in understanding the complex regulation of inflammation.
**Here are some specific areas where 15-HPETE research is important:**
* **Inflammation:** 15-HPETE is involved in both the initiation and resolution of inflammation, making it a potential target for therapeutic interventions.
* **Cardiovascular disease:** Studies suggest that 15-HPETE may play a role in the pathogenesis of cardiovascular disease.
* **Cancer:** 15-HPETE has been implicated in both tumor growth and suppression, highlighting its complex involvement in cancer biology.
* **Neurological disorders:** Some research indicates 15-HPETE may be involved in the pathogenesis of neurodegenerative diseases.
**Future research on 15-HPETE will likely focus on:**
* Elucidating its precise role in various physiological and pathological processes.
* Developing novel therapies targeting 15-HPETE for the treatment of inflammatory, cardiovascular, and other diseases.
**In summary, 15-HPETE is a crucial molecule in the arachidonic acid pathway, influencing inflammation, cardiovascular health, and other physiological processes. Further research is needed to fully understand its complex role and potential therapeutic applications.**

Melanoma A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world. (Stedman, 25th ed; from Rook et al., Textbook of Dermatology, 4th ed, p2445) | 0 | 1.96 | 1 | 0 |

HIV Human immunodeficiency virus. A non-taxonomic and historical term referring to any of two species, specifically HIV-1 and/or HIV-2. Prior to 1986, this was called human T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV). From 1986-1990, it was an official species called HIV. Since 1991, HIV was no longer considered an official species name; the two species were designated HIV-1 and HIV-2. | 0 | 1.98 | 1 | 0 |

Vitreoretinopathy, Proliferative Vitreoretinal membrane shrinkage or contraction secondary to the proliferation of primarily retinal pigment epithelial cells and glial cells, particularly fibrous astrocytes, followed by membrane formation. The formation of fibrillar collagen and cellular proliferation appear to be the basis for the contractile properties of the epiretinal and vitreous membranes. | 0 | 1.99 | 1 | 0 |
Bronchial Hyperreactivity Tendency of the smooth muscle of the tracheobronchial tree to contract more intensely in response to a given stimulus than it does in the response seen in normal individuals. This condition is present in virtually all symptomatic patients with asthma. The most prominent manifestation of this smooth muscle contraction is a decrease in airway caliber that can be readily measured in the pulmonary function laboratory. | 0 | 1.99 | 1 | 0 |

Coronary Disease An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels. | 0 | 2 | 1 | 0 |

Brain Edema Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS). (From Childs Nerv Syst 1992 Sep; 8(6):301-6) | 0 | 2.66 | 3 | 0 |
Brain Ischemia Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION. | 0 | 2.37 | 2 | 0 |
