New approach to predict the enzyme activity using AI

Without enzymes, an organism would not be able to survive. It is these biocatalysts that facilitate a whole range of chemical reactions, producing the building blocks of the cells. Enzymes are also used widely in biotechnology and in our households, where they are used in detergents, for example.

Study investigates the link between gray matter and white matter neurodegeneration in subjective cognitive decline

Aging-US published "The interplay between gray matter and white matter neurodegeneration in subjective cognitive decline" which reported that subjective cognitive complaints were assessed through 9 questions covering amnestic and non-amnestic cognitive domains. In these authors' cohorts, 123 individuals endorsed from one to six subjective cognitive complaints, while 102 individuals reported zero complaints.

Cognitive function of older adults could be improved through multidomain lifestyle interventions

Aging-US published "Facility-based and home-based multidomain interventions including cognitive training, exercise, diet, vascular risk management, and motivation for older adults: a randomized controlled feasibility trial" which reported that in an outcome assessor-blinded, randomized controlled trial, participants without dementia and with one or more modifiable dementia risk factors, aged 60-79 years, were randomly assigned to the facility-based MI, the home-based MI, or the control group receiving general health advice.

Study identifies a novel potential biomarker for hepatocellular carcinoma

Aging-US published "Comprehensive analysis of the competing endogenous circRNA-lncRNA-miRNA-mRNA network and identification of a novel potential biomarker for hepatocellular carcinoma" which reported that there is still a lack of comprehensive analysis of the circular RNA -long non-coding RNA -miRNA-mRNA ceRNA network in hepatocellular carcinoma.

Study investigates the effects of calycosin on breast cancer cell progression

Aging-US published "Calycosin inhibits breast cancer cell migration and invasion by suppressing EMT via BATF/TGF-β1" which reported that in this study, the authors investigated the effects of calycosin on breast cancer cell progression and their underlying mechanisms. Calycosin dose- and time-dependently inhibited proliferation, migration, and invasion by T47D and MCF-7 breast cancer cells by downregulating basic leucine zipper ATF-like transcription factor expression.
