Biomaterials targeting senescent cells for bone regeneration: State-of-the-art and future perspectives [PDF]

Bioactive Materials
Bone defect treatment remains a significant clinical challenge, further exacerbated by the demographic transition toward an aging society. In elderly populations, the increased proportion of senescent cells emerges as a fundamental determinant that ...

Regional Conflict, Ceramic Senescence, and Pawnee Raw Material Choice in the Late Contact Era [PDF]

American Antiquity, 2021
Here, we consider the last decades of ceramic manufacture among the Pawnee in the Central Great Plains, using petrographic analysis to explore raw material availability and use at the Kitkahahki Town site (14RP1). Historical documents reveal tremendous regional pressures and conflicts in the Kitkahahki Town area during its occupation in the late ...

Creation of a collection of different biological sample types from elderly patients to study the relationship of clinical, systemic, tissue and cellular biomarkers of accumulation of senescent cells during aging

Кардиоваскулярная терапия и профилактика, 2022
With aging, tissue homeostasis and their effective recovery after damage is violated. It has been shown that this may be due to the excessive accumulation of senescent (SC) cells in various tissues, which leads to the activation of chronic sterile ...

Extracting Fractional Vegetation Cover from Digital Photographs: A Comparison of In Situ, SamplePoint, and Image Classification Methods

Sensors, 2021
Fractional vegetation cover is a key indicator of rangeland health. However, survey techniques such as line-point intercept transect, pin frame quadrats, and visual cover estimates can be time-consuming and are prone to subjective variations.

Better revisiting chlorophyll content retrieval with varying senescent material and solar-induced chlorophyll fluorescence simulation on paddy rice during the entire growth stages

Ecological Indicators, 2021
Solar-induced chlorophyll fluorescence at 760 nm (SIF) is a promising proxy of photosynthesis and can help improving plant stress monitoring. The Soil-Canopy Observation of Photochemistry and Energy fluxes (SCOPE) model combines radiative transfer and ...

Export of Organic Materials from Developing Fruits of Pea and Its Possible Relation to Apical Senescence [PDF]

Plant Physiology, 1988
In the G2 line of peas (Pisum sativum L.) senescence and death of the apical bud occurs only in long days (LD) in the presence of fruits. Removal of the fruits prevents apical senescence. One possible reason for the senescence-inducing effect of fruit is that the fruits produce a senescence-inducing factor which moves to the apical bud and is ...

Adhesion strength and contractility enable metastatic cells to become adurotactic

Cell Reports, 2021
Summary: Significant changes in cell stiffness, contractility, and adhesion, i.e., mechanotype, are observed during a variety of biological processes. Whether cell mechanics merely change as a side effect of or driver for biological processes is still ...

Translating cell biology of ageing? On the importance of choreographing knowledge

New Genetics and Society, 2021
This paper describes and explores how translational research models, embedded in institutions and standards, interact with the epistemic and material practices of cell biologists of ageing, a field re-energized by emergent technoscientific promises that ...
