“How sad it is! I shall grow old, and horrible, and dreadful” – The ups and downs of cell senescence

Biomedical Journal, 2023
This issue of the Biomedical Journal contains a special section about cell senescence. The reader gets an insight into the crosstalk between immune system and senescent cells, into an approach to fight aging by tweaking macronutrient intake, and also ...

Cellular Damage of Bacteria Attached to Senescent Phytoplankton Cells as a Result of the Transfer of Photochemically Produced Singlet Oxygen: A Review

Microorganisms, 2023
Several studies set out to explain the presence of high proportions of photooxidation products of cis-vaccenic acid (generally considered to be of bacterial origin) in marine environments.

Litterfall and Litter Decomposition in Pinus and Native Forests

Floresta e Ambiente, 2019
Litter production and decomposition makes it possible to supply a good part of the nutrient demand of forest stands. Although several studies on this subject have been carried out in Pinus stands in different regions of Brazil, there are no records of ...

Maple and hickory leaf litter fungal communities reflect pre-senescent leaf communities [PDF]

PeerJ, 2022
Fungal communities are known to contribute to the functioning of living plant microbiomes as well as to the decay of dead plant material and affect vital ecosystem services, such as pathogen resistance and nutrient cycling.

Material-induced Senescence (MIS): Fluidity Induces Senescent Type Cell Death of Lung Cancer Cells via Insulin-Like Growth Factor Binding Protein 5

Theranostics, 2017
Objective: We propose here material-induced senescence (MIS) as a new therapeutic concept that limits cancer progression by stable cell cycle arrest. This study examined for the first time the effect of material fluidity on cellular senescence in lung carcinoma using poly(ε-caprolactone-co-D, L-lactide) (P(CL-co-DLLA)) with tunable elasticity and ...
