Fiber, elastic

Fiber, elastic

A slender fiber in connective tissue that is rich in the protein elastin and has an elastic quality.

RELATED TERMS
--------------------------------------

Fiber
A substance in foods that comes from plants. Fiber helps with digestion by keeping stool soft so that it moves smoothly through the colon. Soluble fiber dissolves in water. Soluble fiber is found in beans, fruit, and oat products. Insoluble fiber does not dissolve in water. Insoluble fiber is found in whole-grain products and vegetables.

Tissue
Biological tissue is a group of cells that perform a similar function.The study of tissues is known as histology, or, in connection with disease, histopathology.The classical tools for studying the tissues are the wax block, the tissue stain, and the optical microscope, though developments in electron microscopy, immunofluorescence, and frozen sections have all added to the sum of knowledge in the last couple of decades.

Protein
Any of a group of complex organic compounds which contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur, the characteristic element being nitrogen. Proteins, the principal constituents of the protoplasm of all cells, are of high molecular weight and consist essentially of combinations of a-amino acids in peptide linkages. Twenty different amino acids are commonly found in proteins, and each protein has a unique genetically defined amino acid sequence which determines its specific shape and function. Their roles include enzymatic catalysis, transport and storage, coordinated motion, nerve impulse generation and many others.

Elastin
A protein that coil and recoils like a spring within the elastic fibers of connective tissue and accounts for the elasticity of structures such the skin, blood vessels, heart, lungs, intestines, tendons, and ligaments. Elastin functions in connective tissue together with collagen. Whereas elastin provides elasticity, collagen provides rigidity to connective tissue. Elastin is normally no longer made after puberty and aging begins. Also called elasticin.

Soluble fiber is found in beans, fruit, and oat products. Insoluble fiber does not dissolve in water. Insoluble fiber is found in whole-grain products and vegetables.

Fiber and bowel disorders
High fiber diets help delay the progression of diverticulosis and, at least, reduce the bouts of diverticulitis. In many cases, it helps reduce the symptoms of the Irritable Bowel Syndrome (IBS) (also called spastic colitis, mucus colitis, and nervous colon syndrome.) It is generally accepted that a diet high in fiber is protective, or at least reduces the incidence, of colon polyps and colon cancer.

Fiber and constipation
Insoluble fiber retains water in the colon, resulting in a softer and larger stool. It is used effectively in treating constipation resulting from poor dietary habits. Bran is particularly rich in insoluble fiber.

Fiber and diabetes
Soluble fibers (oat bran, apples, citrus, pears, peas/beans, psyllium, etc.) slow down the digestion of carbohydrates (sugars), which results in better glucose metabolism. Some patients with the adult-onset diabetes may actually be successfully treated with a high-fiber diet alone, and those on insulin, can often reduce their insulin requirements by adhering to a high-fiber diet.

Fiber FISH
A cytogenetic (chromosome) laboratory technique in which FISH (fluorescence in situ hybridization) is done on chromosomes that have been mechanically stretched. Fiber FISH provides a higher resolution of analysis than conventional FISH and yields more precise information as to the localization of a specific DNA probe on the chromosome.

Fiber, soluble and insoluble
Fiber (the portion of plants that cannot be digested by the human digestive tract) is classified as soluble and insoluble. Oats, beans, dried peas, and legumes are major sources of soluble fiber whereas wheat bran, whole grain products, and vegetables are major sources of insoluble fiber. Fruits, vegetables, and barley are sources of both insoluble and soluble fiber. Soluble fiber and insoluble fiber differ in function. For example, soluble fiber delays the time of transit through the intestine whereas insoluble fiber speeds up intestinal transit. For another example, soluble fiber and decreases the level of cholesterol in the blood whereas insoluble fiber has no effect on serum cholesterol.

FGFR3
Abbreviation for fibroblast growth factor receptor 3. Mutations in the FGFR3 gene are known to cause three different syndromes -- hypochondroplasia, achondroplasia, and thanatophoric dysplasia. These syndromes represent variations in severity. Hypochondroplasia is the mildest and thanatophoric dysplasia (also called thanatophoric dwarfism) is the most severe. In fact, thanatophoric dysplasia is a type of dwarfism in which death usually occurs in the first hours of life. FGF3 is an example of how different syndromes can result from mutations in a single gene.

Fibrates for lowering cholesterol
Fibrates are cholesterol-lowering drugs that are primarily effective in lowering triglycerides and, to a lesser extent, in increasing HDL-cholesterol levels.

Fibril
The diminutive of fiber. A small fiber, a fine thread.

Fibrillation, atrial
An abnormal irregular heart rhythm whereby electrical signals are generated chaotically throughout the upper chambers (atria) of the heart. Although many persons with atrial fibrillation have no symptoms, the most common symptom is palpitations, an uncomfortable awareness of the rapid and irregular heartbeat. Atrial fibrillation can cause blood clots that travel from the heart to the brain, causing stroke. Treatment of atrial fibrillation involves controlling the risk factors, medications to slow the heart rate and/or convert the heart to normal rhythm, and preventing complications of blood clotting.

Fibrillation, auricular
Essentially the same as atrial fibrillation.
