Fiber and bowel disorders
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 i...
Fiber and cholesterol
Fiber and cholesterol: Soluble fiber substances are
effective in helping reduce the blood cholesterol. This is especially true with oat bran,
fruits, psyllium and legumes. High soluble-fiber diets may lower cholesterol and
low-density lipoproteins (the 'bad' lipoproteins) by 8% to 15%....
Fiber and constipation

constipation resulting from poor dietary habits. Bran is particularly rich in insoluble
Fiber and diabetes
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 alon...
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 local...

The difference between fibrillation and flutter is that
fibrillation is not well organized while flutter is.
For example, atrial flutter is regular, organized but over-rapid
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 th...
Fibrillation, auricular: Essentially the same as atrial
Fibrillation, ventricular: An abnormal irregular heart
rhythm whereby there are very rapid uncoordinated fluttering contractions of the lower
chambers (ventricles) of the heart. Ventricular fibrillation disrupts the synchrony between
the heartbeat and the pulse beat. Ventricular fibrillation is comm...
Fibrillin 1: See: FBN1....
Fibrin: The protein formed during normal blood clotting
that is the essence of the clot. ...
