Tonsillar Disease and Capillary Vessels
The three-dimensional structure of capillary vessels in the human palatine tonsil using corrosion casting technique was investigated. The postcapillary venules and arterioles were distinguishable from the nuclear impressions on their walls. The configuration of vessels around cryptal micropores is similar to images obtained by a recently developed cryptscope. The palatine tonsil has no efferent...
متن کاملYoung capillary vessels rejuvenate aged pancreatic islets.
Pancreatic islets secrete hormones that play a key role in regulating blood glucose levels (glycemia). Age-dependent impairment of islet function and concomitant dysregulation of glycemia are major health threats in aged populations. However, the major causes of the age-dependent decline of islet function are still disputed. Here we demonstrate that aging of pancreatic islets in mice and humans...
متن کاملDynamical clustering of red blood cells in capillary vessels.
We have modeled the dynamics of a 3-D system consisting of red blood cells (RBCs), plasma and capillary walls using a discrete-particle approach. The blood cells and capillary walls are composed of a mesh of particles interacting with harmonic forces between nearest neighbors. We employ classical mechanics to mimic the elastic properties of RBCs with a biconcave disk composed of a mesh of sprin...
متن کاملChanges in Blood Vessels (capillary Fragility) with Inflammation
Suction with a partial vacuum of -70 mm. Hg applied to normal skin of rabbits causes intracutaneous hemorrhage after an average time of 8 minutes. Inflammation produced by various agents, including turpentine, killed streptococci, staphylococci, pneumococci or meningococci, and filtrates from cultures of meningococci or typhoid bacilli, produces a series of changes that are almost uniform. Imme...
متن کاملClusters of circulating tumor cells traverse capillary-sized vessels.
Multicellular aggregates of circulating tumor cells (CTC clusters) are potent initiators of distant organ metastasis. However, it is currently assumed that CTC clusters are too large to pass through narrow vessels to reach these organs. Here, we present evidence that challenges this assumption through the use of microfluidic devices designed to mimic human capillary constrictions and CTC cluste...
