Homovanillic acid Homovanillic acid. Homovanillic acid (HVA) is a major catecholamine metabolite that is produced by a consecutive action of monoamine oxidase and catechol-O-methyltransferase on dopamine.[1] Homovanillic acid is used as a reagent to detect oxidative enzymes, and is associated with dopamine levels in the brain. In psychiatry and neuroscience, brain and cerebrospinal fluid levels of HVA are measured as a marker of metabolic stress caused by 2-deoxy-D-glucose. HVA presence supports a diagnosis of neuroblastoma and malignant pheochromocytoma.

- Learn about hypervolemia. Hypervolemia is an abnormal increase in the body's blood volume, particularly in the sense of blood plasma. Plainly speaking, the volume of fluid in the blood is too high in a case of hypervolemia. Diagnosis of a case of hypervolemia may be given by a medical professional or doctor.

- The hematocrit (Ht or HCT, British English spelling haematocrit), also known as packed cell volume (PCV) or erythrocyte volume fraction (EVF), is the volume percentage (%) of red blood cells in blood.Redirected from Packed cell volume). The hematocrit (Ht or HCT, British English spelling haematocrit), also known as packed cell volume (PCV) or erythrocyte volume fraction (EVF), is the volume percentage (%) of red blood cells in blood. It is normally 45% for men and 40% for women.

Variable air volume Variable air volume. Variable Air Volume (VAV) is  a type of heating, ventilating, and/or air-conditioning (HVAC) system. Unlike constant air volume (CAV) systems, which supply a constant airflow at a variable temperature, VAV systems vary the airflow at a constant temperature.

The function of vena cava? The inferior vena cava is one of two veins which carries deoxygenated blood from the body into the right atrium of the heart, the other vein is the superior vena cava: inferior deals with blood coming from body areas below the heart, superior deals with blood coming from above the heart.he inferior vena cava is the large vein that carries de-oxygenated blood from the lower half of the body into the right atrium of the heart.

Hypervariable region A hypervariable region (HVR) is a location within nuclear DNA or the D-loop of mitochondrial DNA in which base pairs of nucleotides repeat (in the case of nuclear DNA) or have substitutions (in the case of mitochondrial DNA).Changes or repeats in the hypervariable region are highly polymorphic.n some bony fishes, for example certain Protacanthopterygii and Gadidae, the mitochondrial control region evolves remarkably slowly. Even functional mitochondrial genes accumulate mutations faster and more freely. It is not known whether such hypovariable control regions are more widespread.

Inferior vena cava Inferior vena cava. The inferior vena cava is also referred to as the posterior vena cava. The inferior vena cava is a large vein that carries de-oxygenated blood from the lower body to the heart. De-oxygenated blood means most of the oxygen has been removed by tissues, and therefore the blood is darker.he inferior vena cava empties into the right atrium of the heart. The right atrium is located on the lower right back side of the heart. The inferior vena cava runs posterior, or behind, the abdominal cavity.

Bodybuildingâs Mounting Death Toll â Part 1 Hematocrit, also known as PCV (packed-cell volume), is the concentration of red blood cells in the blood. The higher hematocrit is, the greater the percentage of red blood cells in the blood, while lower hematocrit levels signify a lower percentage of red blood cells.

Hypervolemia Not to be confused with volume overload. Hypervolemia, or fluid overload, is the medical condition where there is too much fluid in the blood. The opposite condition is hypovolemia, which is too little fluid volume in the blood. Fluid volume excess in the intravascular compartment occurs due to an increase in total body sodium content and a consequent increase in extracellular body water.

- Hematocrit. The hematocrit (Ht or HCT, British English spelling haematocrit), also known as packed cell volume (PCV) or erythrocyte volume fraction (EVF), is the volume percentage (%) of red blood cells in blood. It is normally 45% for men and 40% for women.ecause the purpose of red blood cells is to transfer oxygen from the lungs to body tissues, a blood sample's hematocrit—the red blood cell volume percentage—can become a point of reference of its capability of delivering oxygen.

What does HGB and HCT mean when it has to do with blood tests? Hematocrit (HCT, packed cell volume, PCV). This test measures the amount of space (volume) red blood cells take up in the blood. The value is given as a percentage of red blood cells in a volume of blood. For example, a hematocrit of 38 means that 38% of the blood's volume is made of red blood cells.

Hypoxia (medical) Hypoxia (also known as hypoxiation or anoxemia) is a condition in which the body or a region of the body is deprived of adequate oxygen supply. Hypoxia may be classified as either generalized, affecting the whole body, or local, affecting a region of the body.actic acid build up (in tissues and blood) is a sign of inadequate mitochondrial oxygenation, which may be due to hypoxemia, poor blood flow (e.g., shock) or a combination of both. If severe or prolonged it could lead to cell death. In humans, hypoxia is detected by chemoreceptors in the carotid body.

Mean corpuscular volume The mean corpuscular volume, or mean cell volume (MCV), is a measure of the average volume of a red blood corpuscle (or red blood cell). The measure is attained by multiplying a volume of blood by the proportion of blood that is cellular (the hematocrit), and dividing that product by the number of erythrocytes (red blood cells) in that volume. The mean corpuscular volume is a part of a standard complete blood count. In a laboratory test that computes MCV, erythrocytes are compacted during centrifugation.

Hyperaemia [edit on Wikidata] Hyperaemia, hyperæmia, or hyperemia (Greek ὑπέρ (hupér, “over”) + αἷμα (haîma, “blood”)) is the increase of blood flow to different tissues in the body. It can have medical implications, but is also a regulatory response, allowing change in blood supply to different tissues through vasodilation.

- Ventricular hypertrophy (VH) is thickening of the walls of a ventricle (lower chamber) of the heart. Although left ventricular hypertrophy (LVH) is more common, right ventricular hypertrophy (RVH), as well as concurrent hypertrophy of both ventricles can also occur.
