Translations in context of "parenchymal cell" in English-French from Reverso Context: Prior to insertion, subsequent to insertion, or concurrent with insertion the permeability of the vessel is increased thereby the genetic material is delivered to the parenchymal cell altering endogenous properties of the cell. This article describes the historical classifications of breast density. The available evidence indicates, therefore, that mammographic parenchymal patterns do, at least in part, meet the criteria outlined in the introduction of this paper. 2006 Dec;176(6 Pt 1):2401-4. doi: 10.1016/j.juro.2006.08.008. According to Hortega, the structural pattern of the parenchyma is that of a gland: he stated that the ‘Knowledge gathered thus far enables … to affirm that the cells … are elements differentiated for the discharge of a non-nervous function … probably a secretory function’. Some mammographic appearances are associated with a substantial increase in the risk of breast cancer, and, as shown by observations on the effects of hormone use, are capable of change. According to Dictionary.com, the word "parenchymal" is an anatomical term that refers to the "specific tissue of an animal organ." In people, the cells that perform the primary function of the organ of the “structural” cells serve primarily to protect or shape the parenchyma.

Belong to Parenchymal liver disease affects the actual liver cells directly instead of those of supporting tissue, such as the bile ducts. Parenchyma cells can be categorised based on their structure, location and functions performed. Patient were described with hilar nodes and parenchymal changes as well as extra-pulmonary findings. The main parenchyma tissues are: Chlorenchyma: Cells which have chloroplast and perform photosynthesis The mesophyll cells in leaves which differentiate into palisade and spongy cells; In the other green parts of the plants like stems, sepal etc. The parenchyma are the functional parts of an organ in the body. It is important to understand the word properly when we translate it from English to Hindi. That is why practically all the functions that are carried out inside the body of an individual, except the structural and protective functions, are performed by parenchymal cells . Obesity and insulin resistance are the most common risk factors for hepatic steatosis, but it also may be associated with a number of metabolic processes and toxins (Box 90-1). While the terms mesenchymal stem cell (MSC) and marrow stromal cell have been used interchangeably for many years, neither term is sufficiently descriptive: . The parenchymal cells that make up this tissue are immature, multi-nucleated, and non-vacuolated. Mesenchyme is embryonic connective tissue that is derived from the mesoderm and that differentiates into hematopoietic and connective tissue, whereas MSCs do not differentiate into hematopoietic cells. ma (pə-rĕng′kə-mə) n. 1.
