WebAtorvastatin suppressed TNF-α-induced matrix degradation in rat NP cells. (a) The CCK-8 assay was used to detect the toxicity of atorvastatin at various concentrations and for different time points in rat NP cells. (b) Real-time PCR was used to test the effect of 20 μM atorvastatin on catabolic gene mRNA expression induced by 50 ng/mL TNF-α. Web1 dec. 2024 · Wrinkle formation is known to be closely associated with the degradation of the extracellular matrix (ECM) of the skin, and UV radiation induces the degradation of ECM via complex signaling events including collagen fragmentation and matrix metalloproteinases (MMPs) secretion [ 6 ].

Depending on the vector norms ‖ ‖, ‖ ‖ used, notation other than ‖ ‖, can be used for the operator norm.. Matrix norms induced by vector p-norms. If the p-norm for vectors is used for both spaces … Meer weergeven In mathematics, a matrix norm is a vector norm in a vector space whose elements (vectors) are matrices (of given dimensions). Meer weergeven These norms treat an $${\displaystyle m\times n}$$ matrix as a vector of size $${\displaystyle m\cdot n}$$, and use one of the … Meer weergeven A matrix norm $${\displaystyle \ \cdot \ }$$ is called monotone if it is monotonic with respect to the Loewner order. Thus, a matrix norm is increasing if Meer weergeven For any two matrix norms $${\displaystyle \ \cdot \ _{\alpha }}$$ and $${\displaystyle \ \cdot \ _{\beta }}$$, we have that: for some … Meer weergeven Suppose a vector norm $${\displaystyle \ \cdot \ _{\alpha }}$$ on $${\displaystyle K^{n}}$$ and a vector norm $${\displaystyle \ \cdot \ _{\beta }}$$ on $${\displaystyle K^{m}}$$ are given.
