Definition is a rhetorical mode that can be used in something smaller or shorter than a full paper. You can use extended definition for several paragraphs only in a paper of much greater length. You also can add to a paper a one-paragraph definition--like a brief encyclopedia definition.
Depending upon location, neural crest cells give rise to most of the peripheral nervous system, as well as various non-neural tissues, like craniofacial bone and cartilage, the thymus and parathyroid glands, and the cardiac outflow tract â in short, all of the tissues that are affected in DiGeorge syndrome.
The contraction of mesangial cells involves the interplay of many signal transduction pathways, including both PKC and intracellular calcium concentration ([Ca 2+ ] i) (10, 22). The role of PKC and [Ca 2+ ] i in the effects of adriamycin on contractile function of mesangial cells is currently unclear.In adriamycin nephrotoxicity, a pathological change in glomeruli is initially manifested by glomerular hypertension and hyperfiltration (5, 12, 26).o evaluate the extent to which calcium-induced contraction was impaired by adriamycin treatment, [Ca 2+ ] i, expressed as the F340/F380 ratio, was measured in fura 2-loaded mesangial cells.
