- The suspicious stone was in the gallbladder instead of the duodenal lumen.
- Vitamins, minerals, salts and antibodies are transformed from the blood across the cell cytoplasm into the alveolar lumen, demonstrated in the picture below.
- The effect of PTX is probably the result of decreased protein leakage from the capillaries to the alveolar lumen.
- Microscopic observations of lungs of mice infected with B. pertussis showed that the bacteria grow as clusters within the alveolar lumen.
- Thyroglobulin, which contains the thyroid hormones, is stored in the follicular lumen until needed.
- Binary restenosis was defined as stenosis of more than 50% of the lumen diameter in the target lesion.
- In eukaryotic cells, disulfide bonds are generally formed in the lumen of the RER (rough endoplasmic reticulum) but not in the cytosol.
- It is in the saints that "God shows to men, in a vivid way, his presence and his face" (Lumen gentium, n.
- Generally an atheroma becomes vulnerable if it grows more rapidly and has a thin cover separating it from the bloodstream inside the arterial lumen.
- We studied 444 men with asymptomatic carotid stenosis shown arteriographically to reduce the diameter of the arterial lumen by 50 percent or more.
- A Lux is a lumen per square meter, which we might call illumination in street jive, but illuminance in sci.optics talk.
- The lowest pH of the secreted acid is 0.8,[ 1] but the acid is diluted in the stomach lumen to a pH between 1 and 3.
- The preferred test is a colonoscopic examination, which can directly visualize the colonic lumen even in the presence of numerous diverticula.
- The blood will travel through the media, creating a false lumen (the true lumen is the normal conduit of blood in the aorta).
- The diagnosis of aortic dissection can be made by visualization of the intimal flap and flow of contrast material in both the true lumen and the false lumen.
- In aortic dissection, one channel (called the true lumen) continues to follow the normal course and delivers blood and oxygen to other parts of the body.
- The SI unit of luminous energy is the lumen second, which is unofficially known as the Talbot in honor of William Henry Fox Talbot.
- The acini consist of two layers of cells placed on a thin hyaline basement membrane and surrounding a central lumen.
- In one embodiment, the system includes a guide wire extending through the central lumen of the catheter and the flexible tube.
- The sheet is the early embryonic ectoderm, and the cylinder that results is the neural tube with its central lumen, or opening.
- Sodium ions and water then follow the chloride ions into the lumen, and the water softens the stool.
- Therefore, to maintain a charge balance in the lumen, sodium is carried with it, along with water.
- Lactulose, a nonabsorbable synthetic sugar that keeps sodium and water inside the intestinal lumen, relieves constipation.
- Saline laxatives attract and retain water in the intestinal lumen, increasing intraluminal pressure and thus softening the stool.
- More severe disease states include thinning of the bowel, susceptibility to ulcers, fibrosis, contraction, and narrowing of the intestinal lumen.
- Barium is an inert substance that coats the internal lining of the bowel and fills up its lumen.
- These peptides are also highly digestible, therefore reducing their retention time in the lumen of the intestine.

- This reduces the volume of the tissue fragments as they pass through suction lumen to minimize clogging of the lumen.
- This problem was surmounted in 1999 with the invention of the stratified continuous (inner) lumen, and the kinetic acoustic mechanism in 2002.
- However, IVUS enables more accurately visualizing not only the lumen of the coronary arteries but also the atheroma "hidden" within the wall.
- Inside the testis, from the wall into the lumen, successive stages of spermatogenesis occur, and germ cells are nourished by supporting Sertoli's cells.
- Side lobes may obscure the true lumen and stent borders, interfering with area measurements and the assessment of apposition, dissection, etc.
- Occlusion occurs as a result of coil-induced thrombosis rather than mechanical occlusion of the lumen by the coil.
