Cytology is the name given to the branch of biology that deals with the formation, structure and functionality of the cells. [1] Liver cytology specializes in the study of liver cells. The main liver cells are called hepatocytes; however, there are other cells that can be observed in a liver sample such as Kupffer cells (macrophages). [2]
A high gradient (> 1.1 g/dL, >11 g/L) indicates the ascites is due to portal hypertension, either liver related or non-liver related, with approximately 97% accuracy. [2] This is due to increased hydrostatic pressure within the blood vessels of the hepatic portal system , which in turn forces water into the peritoneal cavity but leaves proteins ...
The Terminologia Histologica (TH) is the controlled vocabulary for use in cytology and histology. [1] [2] In April 2011, Terminologia Histologica was published online [3] by the Federative International Programme on Anatomical Terminologies (FIPAT), the successor of FCAT. It was intended to replace Nomina Histologica.
In COVID-19 B cell, natural killer cell, and total lymphocyte counts decline, but both CD4 + and CD8 + cells decline to a far greater extent. [12] Low CD4 + predicted greater likelihood of intensive care unit admission, and CD4 + cell count was the only parameter that predicted length of time for viral RNA clearance.
Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision. Microscopic anatomy is the study of minute anatomical structures assisted with microscopes, and includes histology (the study of the organization of tissues), and cytology (the study of ...
Liver function tests (LFTs or LFs), also referred to as a hepatic panel or liver panel, are groups of blood tests that provide information about the state of a patient's liver. [1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin , bilirubin (direct and indirect), and others.
Gastric signet ring cell carcinoma histopathology, PAS stain Esophageal candidiasis, PAS stain Liver in glycogen storage disease, PAS stain. PAS staining is mainly used for staining structures containing a high proportion of carbohydrate macromolecules (glycogen, glycoprotein, proteoglycans), typically found in e.g. connective tissues, mucus, the glycocalyx, and basal laminae.
Examples of inclusions are glycogen granules in the liver and muscle cells, lipid droplets in fat cells, pigment granules in certain cells of skin and hair, and crystals of various types. [3] Cytoplasmic inclusions are an example of a biomolecular condensate arising by liquid-solid, liquid-gel or liquid-liquid phase separation .
