"Cholesterols" Natural Recordings by Native Speakers
Cholesterols are a type of fat molecule found in the bloodstream, particularly in the liver, and are an essential component of cell membranes. There are two main types of cholesterol: high-density lipoprotein (HDL) cholesterol, which is considered "good" cholesterol because it helps remove excess cholesterol from the bloodstream and transport it to the liver for excretion, and low-density lipoprotein (LDL) cholesterol, which is considered "bad" cholesterol because it tends to build up in the walls of the arteries, increasing the risk of heart disease.
A rare and chronic condition that is a type of cyst or abscess filled with cholesterol and other debris in the temporal bone of the skull, caused by a combination of infection, inflammation, and faulty drainage. It can lead to serious complications, such as hearing loss, facial weakness, and meningitis, if left untreated.
Cholesteatomas are abnormal growths that can occur in the middle ear, mastoid air cells, or the petrous portion of the temporal bone. They are typically benign, but can be destructive and recur if not removed surgically. Cholesteatomas are composed of desquamated squamous epithelial cells, keratin, and other debris that accumulate and cause inflammation and destruction of surrounding bone.
Cholesteatomata refers to a type of benign tumor that arises from the middle ear cleft, typically within the mastoid air cells or the posterior wall of the external auditory canal. It is characterized by the formation of a cholesterol-filled sac that can cause inflammation, infection, and even rupture, leading to complications such as hearing loss, facial paralysis, and meningitis.
Cholesteric refers to a type of liquid crystal exhibiting a specific arrangement of rod-shaped molecules, characterised by the presence of a cholesteric phase. In this phase, the rod-shaped molecules are hexagonally packed and rotate in a screw-like manner as a function of depth.
Cholesterol is a waxy, fat-like substance that is found in the bloodstream and in every cell of the body. It is a type of lipid, or fat molecule, and is an important component of the cell membranes of animals, including humans. Cholesterol is used by the body to produce bile, vitamin D, and hormones, such as estrogen and testosterone.
Cholesterol is a waxy, fat-like substance found in the bloodstream and in all cells of the body. It plays a crucial role in the formation of bile, which aids in the digestion and absorption of fats, vitamins, and other nutrients. However, high levels of cholesterol in the blood can increase the risk of heart disease and stroke.
Cholesterolemia is a medical term that refers to an abnormal amount of cholesterol in the bloodstream. Specifically, it can be used to describe either elevated cholesterol levels (hypercholesterolemia) or low cholesterol levels (hypochlorysterolemia).
Cholesterolosis is a medical condition characterized by the abnormal accumulation of cholesterol in the gallbladder, often causing gallstones. It can present with symptoms such as abdominal pain, nausea, vomiting, and fever, and is typically treated with surgery to remove the gallbladder.
Cholesterosis refers to a condition characterized by the deposition of cholesterol crystals in the walls of blood vessels, typically in the liver, kidneys, and gallbladder. It can cause symptoms such as jaundice, itching, and abdominal pain, and may be a sign of underlying liver or bile duct problems.
Cholesteryl refers to a type of steroid found in animals, particularly in cholesterol, the primary component of animal cell membranes.
A choliamb is a rare and ancient Greek poetic form, also known as a "limping dactyl". It consists of four lines, with a specific pattern of long and short syllables. The first, second, and fourth lines have seven syllables each, with a distinct pattern of long and short syllables, while the third line has five syllables. The choliamb was often used by ancient Greek poets to express witty or humorous observations, and was considered a more casual and colloquial form of poetry compared to other forms like the hexameter or elegiac couplet.
Choliambic refers to a type of ancient Greek verse that consists of six feet, with the first, second, fourth, and fifth feet unstressed, and the third and sixth feet stressed. It is also known as the "Jambi" or "Lambi". The choliambic meter is characterized by a distinctive, uneven rhythm, which is often described as "limping" or "crabbed".
Choline is a nutrient that is a vital component of many biomolecules, such as phospholipids, sphingolipids, and bile salts. It plays a key role in numerous bodily functions, including cell membrane structure, metabolic processes, and neurotransmission. Choline is also known as vitamin B4 and is an essential nutrient for humans, meaning it cannot be produced naturally by the body and therefore must be obtained through the diet or supplements. Foods rich in choline include eggs, meat, fish, and soybeans. Choline has been linked to several health benefits, including improved brain function, liver health, and fertility.
Cholinergia is a rare medical condition characterized by the excessive release of the neurotransmitter acetylcholine in the brain and spinal cord. It is often caused by a tumor or other growth on the parasympathetic nerve fibers that produce acetylcholine. Symptoms typically include excessive sweating, diarrhea, urination, and salivation, as well as muscle weakness and twitching. The condition is usually treated with medications that help to reduce the production of acetylcholine or block its action on nerve cells.
