The phrase "activity of apps" is correct and usable in written English.
It can be used to refer to the actions or functions performed by applications, particularly in discussions about technology or software.
Example: "The activity of apps on mobile devices can significantly impact battery life and performance."
Alternatives: "functionality of apps" or "operations of applications".
The degree to which APP function plays a role in the pathogenesis of AD is unclear but changes in the apoptotic and axonal activities of APP may underlie some aspects of AD pathology [5], [6].
Using our multi-compartment model, we (i) established the activity distribution of APP in various compartments, and (ii) traced the activity distribution of APP, α-secretase, β-secretase and SORLA in the monomeric and dimeric processing of APP.
These original humanized APP mice were generated in this manner to potentially avoid any effects that could arise from any human APP specific activities of holo APP or shed APP ectodomains.
Basal activity of the APP promoter is greatest in neural origin cell lines, and several promoter elements close to the PRE are important for this activity [ 108].
The Galaxy Gear and Smartwatch 2 both offer a range of activity apps of their own as well as other Android software, but rely on being paired with a smartphone for much of their functionality.
"With our Series B round of financing, we shifted our focus to data analysis and expanded the scope of our coverage beyond analysis of user activity to App Store/Google Play market data and purchase history data.
The observed high antimicrobial activity of the combination of APP and low salt levels (e.g., 2.5% APP and 0.5% salt) suggests that commercial and home processors of meat could reduce the salt concentration by adding APP to the ground meat.
The proteolytic activity of KLK6 against APP and substrates in the extracellular matrix and perineuronal net places this peptidase as a potential component of AD pathogenesis.
Similar, metformin was also shown to increase Aβ levels by up-regulating the activity of beta-site APP-cleaving enzyme 1 (BACE1), which could account for increased risk of AD development in diabetic patients treated with metformin (Imfeld et al., 2012, Moore et al., 2013).
