Transudate is extravascular fluid with low protein content and a low specific gravity (< 1.012). It has low nucleated cell counts (less than 500 to 1000 per microliter) and the primary cell types are mononuclear cells: macrophages, lymphocytes and mesothelial cells. For instance, an ultrafiltrate of blood plasma is transudate.
Thoracentesis / ˌ θ ɔː r ə s ɪ n ˈ t iː s ɪ s /, also known as thoracocentesis (from Greek θώραξ (thōrax, GEN thōrakos) 'chest, thorax' and κέντησις (kentēsis) 'pricking, puncture'), pleural tap, needle thoracostomy, or needle decompression (often used term), is an invasive medical procedure to remove fluid or air from the pleural space for diagnostic or therapeutic ...
A chylothorax is an abnormal accumulation of chyle, a type of lipid-rich lymph, in the pleural space surrounding the lung.The lymphatic vessels of the digestive system normally return lipids absorbed from the small bowel via the thoracic duct, which ascends behind the esophagus to drain into the left brachiocephalic vein.
All nucleated cells: Dendritic cells, mononuclear phagocytes, B lymphocytes, some endothelial cells, epithelium of thymus: T lymphocytes able to respond Cytotoxic T lymphocytes (CD8+) Helper T lymphocytes (CD4+) Origin of antigenic proteins cytosolic proteins (mostly synthesized by the cell; may also enter from the extracellular medium via ...
The cell nucleus (from Latin nucleus or nuculeus 'kernel, seed'; pl.: nuclei) is a membrane-bound organelle found in eukaryotic cells.Eukaryotic cells usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others including osteoclasts have many.
It is typically difficult to experimentally study the nucleation of crystals. The nucleus is microscopic, and thus too small to be directly observed. In large liquid volumes there are typically multiple nucleation events, and it is difficult to disentangle the effects of nucleation from those of growth of the nucleated phase.
In cell biology, microtubule nucleation is the event that initiates de novo formation of microtubules (MTs). These filaments of the cytoskeleton typically form through polymerization of α- and β-tubulin dimers, the basic building blocks of the microtubule, which initially interact to nucleate a seed from which the filament elongates.
Human blood after separation by centrifugation. Plasma (upper layer), buffy coat (middle, white-colored layer) and erythrocyte (red blood cell) layer (bottom) can be seen. The buffy coat is commonly used for DNA extraction, [4] with leukocytes providing approximately 10 times more concentrated sources of nucleated cells. [5]
