Effects of leaf age during drought and recovery on photosynthesis, mesophyll conductance and leaf anatomy in wheat leaves

open access: yesFrontiers in Plant Science, 2023
Summary statement: Mesophyll conductance (gm) was negatively correlated with wheat leaf age but was positively correlated with the surface area of chloroplasts exposed to intercellular airspaces (Sc).

Hydroxyapatite Reinforced Polyvinyl Alcohol/Polyvinyl Pyrrolidone Based Hydrogel for Cartilage Replacement

open access: yesGels, 2022
Polyvinyl alcohol (PVA) and Polyvinyl Pyrrolidone (PVP) hydrogels are desirable biomaterials for soft tissue repair and replacement. However, the bio-inertness and poor cell adhesive potency of the PVA and PVP hinder the wide range of biomedical ...

A putative telomerase activator has tissue‐specific effects on telomere length in a developing songbird

open access: yesJournal of Avian Biology, 2021
There is good evidence that telomeres predict variation in health and longevity, yet it is unclear whether these patterns are causally derived from telomeres per se, in part because relatively little research directly manipulates telomere length during ...

Putative Cancer Stem Cell Markers are Frequently Expressed by Melanoma Cells in Vitro and in Situ but are also Present in Benign Differentiated Cells

open access: yesFrontiers in Bioscience-Landmark, 2023
Background: Currently, there remains an incomplete view of cancer stem cells (CSCs) in solid tumours. Methods: We studied a panel of putative CSC surface markers (ALDH1A1, ABCG2, CD44v7/8, CD44v10, CD133, CD271, and Nestin) in 40 established melanoma ...

Tissue-Specific Molecular Markers and Heterogeneity in Type 2 Innate Lymphoid Cells

open access: yesFrontiers in Immunology, 2021
Innate lymphoid cells (ILCs) are the most recently described group of lymphoid subpopulations. These tissue-resident cells display a heterogeneity resembling that observed on different groups of T cells, hence their categorization as cytotoxic NK cells ...
