Computer Modelling of Dental Plaque in Relation to Dental Caries

Microbial Ecology in Health & Disease, 1990
The complex interplay of diffusion and reaction during a cariogenic challenge to the tooth, after sugar ingestion, is considered in terms of mathematical modelling of the dental plaque using finite-difference computer techniques. A discussion of some of the factors which might be included in a model is followed by a brief review of previous models and ...

The role of fibroblast growth factors in cell and cancer metabolism

FEBS Letters, EarlyView.
Fibroblast growth factor (FGF) signaling regulates crucial signaling cascades that promote cell proliferation, survival, and metabolism. Therefore, FGFs and their receptors are often dysregulated in human diseases, including cancer, to sustain proliferation and rewire metabolism.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

The rapidly growing landscape of RAS inhibitors: from selective allele blockade to broad inhibition strategies

Molecular Oncology, EarlyView.
RAS‐targeted therapies have become a clinical reality. Although promising results in patients have been achieved, there are still challenges ahead such as coping with drug resistance. Here we summarize selected RAS inhibitors targeting either individual KRAS mutant isoforms (KRASG12C, KRASG12D, KRASG12V) or exhibiting a wider inhibitory spectrum ...
