"Dextrometer" Natural Recordings by Native Speakers
A dextrometer is a scientific instrument used to measure the specific gravity, or relative density, of a liquid, particularly blood. It is commonly used in medical settings to diagnose and monitor various conditions, such as hypovolemic shock, dehydration, and certain types of anemia. The instrument measures the refractive index of the liquid, which is closely related to its density, allowing for accurate calculation of its specific gravity.
Dextrin is a type of carbohydrate that is produced when starch is broken down during the process of gelatinization. It is a branched-chain polymer of glucose units and is often used as a filler in foods, pharmaceuticals, and toothpaste.
Dextrinoid refers to a chemical property of certain substances that exhibit dextrorotatory properties, meaning they rotate the plane of polarized light in a clockwise direction (dexter means "right" or "correct" in Latin). This property is often used in analytical chemistry to identify and distinguish between different compounds. In simpler terms, a dextrinoid is something that has a specific chemical property that can be detected by a test involving polarized light.
Dextroamphetamine is a central nervous system stimulant medication primarily used to treat attention deficit hyperactivity disorder (ADHD). It works by increasing the levels of certain neurotransmitters in the brain, such as dopamine and norepinephrine, which help regulate attention, impulse control, and hyperactivity. It is also used, in combination with other medications, to treat narcolepsy, a sleep disorder characterized by excessive daytime sleepiness.
Dextrocardia is a rare congenital heart defect in which the heart is located on the right side of the chest, rather than the left side as is typical in humans. This occurs when the embryo's heart fails to rotate properly during fetal development, resulting in the heart and other surrounding organs developing in the mirror image of what is normal. As a result, the dextrocardia may also be accompanied by other unusual anatomical features, such as the liver or stomach being on the right side of the abdomen. In most cases, the heart functions normally, but in some cases, it may not and surgery may be necessary to repair any defects.
Dextrogastria is a rare congenital anomaly in which the stomach and some of the adjoining organs are situated on the right side of the abdominal cavity, rather than the left. It occurs when the embryonic midgut fails to rotate properly during fetal development.
Dextrogyrate refers to a chemical or biological substance that rotates the plane of polarized light to the right, or clockwise, when it passes through it. This is the opposite of levogyrate, which rotates the plane of polarized light to the left, or counterclockwise. The term is often used in chemistry and biochemistry to describe the optical rotation of a molecule.
Dextromethorphan is a medication used to relieve coughing due to a dry or irritated throat. It is a cough suppressant, which means it helps to reduce the urge to cough.
Dextrorotary refers to a chemical compound that rotates plane-polarized light in a clockwise direction. This term is used in stereochemistry to describe the direction of rotation of a chiral molecule. In other words, it means that the compound turns light to the right when it passes through it.
Dextrorotation refers to a type of rotation or turning motion that is to the right or in a clockwise direction. It is commonly used in medical and scientific contexts to describe the rotation of the abdominal organs or other structures in the body. In a surgical context, dextrorotation can refer to the rotation of a structure, such as the liver or the spleen, to the right side of the abdomen.
Dextrose is a type of sugar that is a component of starch, often used as a sweetener or thickening agent in food products, particularly in baked goods, desserts, and energy drinks. It is also used as a medical treatment for hypoglycemia (low blood sugar) due to its rapid absorption and increased energy release.
