Recovering a matrix from a sampling of its entries is a problem of rapidly growing interest and has been studied under the name of matrix completion. It occurs in many areas of engineering and applied science. In most machine learning and data mining applications, it is possible to leverage the expertise of human oracles to improve the performance of ...

Enzymatic activity in the activated-sludge floc matrix
Applied Microbiology and Biotechnology, 1995The enzymatic activity of activated sludge was investigated with special emphasis on the localization of the enzymes in the sludge floc matrix. Activated sludge from an advanced activated-sludge treatment plant, performing biological N and P removal, was used. An enzymatic fingerprint was established using a panel of six different enzymes.

Matrix Metalloproteinases and Leukocyte Activation
2017As their name implies, matrix metalloproteinases (MMPs) are thought to degrade extracellular matrix proteins, a function that is indeed performed by some members. However, regardless of their cell source, matrix degradation is not the only function of these enzymes.

Active Multivariate Matrix Completion
2018Matrix completion has been rapidly grown interested in areas of engineering and applied science. however, most of applications are aim at single variate matrix. In fact, majority applications datasets express in form of multivariate matrix, developing multivariate matrix application is very necessary.

Influence of Homocysteine on Matrix Metalloproteinase-2: Activation and Activity
Biochemical and Biophysical Research Communications, 1999Increased levels of the physiological amino acid homocysteine (Hcy) are considered a risk factor for vascular disease. Hyperhomocysteinemia causes an intense remodelling of the extracellular matrix in arterial walls, particularly an elastolysis involving metalloproteinases.

Structural biochemistry and activation of matrix metalloproteases
Current Opinion in Cell Biology, 1993The degradation of the extracellular matrix is part of many pathological and physiological processes. Of the several proteases involved in extracellular matrix turnover, the plasmin/plasminogen activator system and the family of matrix metalloproteases have received the most attention.

Plasminogen Activators and Matrix Metalloproteinases in Angiogenesis
Enzyme and Protein, 2017In the initial stages of capillary formation (angiogenesis) microvascular endothelial cells of preexisting blood vessels locally degrade the underlying basal lamina and invade into the stroma of the tissue to be vascularized. A consistent body of experimental evidence has shown that this process requires a wide array of dedradative enzymes.

Matrix Metalloproteinases and Cellular Fibrinolytic Activity
Biochemistry (Moscow), 2002Several molecular interactions between the matrix metalloproteinase (MMP) and the plasminogen/plasmin (fibrinolytic) system may affect cellular fibrinolysis. MMP-3 (stromelysin-1) specifically hydrolyzes urokinase (u-PA), yielding a 17 kD NH2-terminal fragment containing the functionally intact receptor (u-PAR)-binding sequence and a 32 kD COOH ...
