FIBRINOLYTIC ACTIVATOR ACTIVITY IN HUMAN NEOPLASMS

Plastic and Reconstructive Surgery, 1978
The results of this study suggest that many malignant tumors contain low levels of fibrinolytic activator activity. Evidence is presented to suggest that this low activity may be due to the presence of an inhibitor of fibrinolysis. The presence or absence of measurable fibrinolytic activator activity, and/or inhibitor in neoplastic growths may enable ...

Cholinephosphotransferase activity in human platelets

Lipids, 1983
AbstractDisrupted human platelets possess a cholinephosphotransferase activity (EC 2.7.8.2) whose properties have been studied in this work. The labeling of choline glycerophospholipid (CGP) from radioactive cytidine‐5′‐diphosphate choline (CDP‐choline) in vitro shows a maximum at pH 8.0 (using Hepes [4‐(2‐hydroxyethyl)‐piperazine‐1‐ethane‐2‐sulfonic ...

Human activity analysis

ACM Computing Surveys, 2011
Human activity recognition is an important area of computer vision research. Its applications include surveillance systems, patient monitoring systems, and a variety of systems that involve interactions between persons and electronic devices such as human-computer interfaces.

Active Sensing in Human Activity Recognition

2017
This work studies the problem of reducing the energy consumption of wearable sensors in a Human Activity Recognition (HAR) system. A HAR system is implemented using Hidden Markov Models, where decisions over the acquisition of new data are made based on the entropy of the posterior distribution of the activities. This problem is intractable in general,

Effectors of the activation of human [Glu1]plasminogen by human tissue plasminogen activator

Biochemistry, 1988
The activation of human [Glu1]plasminogen [( Glu1]Pg) by human recombinant (rec) two-chain tissue plasminogen activator (t-PA) is inhibited by Cl-, at physiological concentrations, and stimulated by epsilon-aminocaproic acid (EACA), as well as fibrin(ogen).

Timespace of Human Activity

2010
This book shows that a concept of activity timespace drawn from the work of Martin Heidegger provides new insights into the nature of activity, society, and history. Although the book is a work of theory, it has significant implications for the determination and course, not just of activity, but of sociohistorical change as well ...

Regulation of proteasome activity in activated human platelets

Cell Calcium, 2011
Ubiquitin-proteasome system has emerged a central player in regulation of diverse cellular processes. However, relevance of proteasome activity in platelets, which are terminally differentiated enucleate cells, is not clear. In this report we show that activation of platelets with physiological agonists was associated with 7-10 -fold rise in ...

Plasminogen activator activity in human endometrial carcinoma

Gynecologic Oncology, 1985
Plasminogen activator activity (PAA) has been proposed as an indicator of aggressiveness of tumors and has been shown to be hormonally modulated. To test this hypotheses in human endometrial carcinoma, tumor explants were assayed for PAA secretion and the results correlated with histopathologic criteria of aggressiveness.

Recognition of Human Activities

2011
Computer Vision is the estimation of the three dimensional shape and other properties of objects based on their two dimensional (projection) images through the use of computers and cameras. It had its beginning in the early 1960s. At the time, it was thought to be an easy problem with a solution probably possible over a summer.
