Characterization of immune cells in periodontitis using a new histological immunologic gingival (IG) score

open access: yesScientific Reports
Periodontitis is a prevalent chronic inflammatory disease due to the host response to dysbiotic biofilm. Immunohistochemistry is often used for a better and more functional tissue characterization.

The Senolytic Drug Navitoclax (ABT-263) Causes Trabecular Bone Loss and Impaired Osteoprogenitor Function in Aged Mice

open access: yesFrontiers in Cell and Developmental Biology, 2020
Senescence is a cellular defense mechanism that helps cells prevent acquired damage, but chronic senescence, as in aging, can contribute to the development of age-related tissue dysfunction and disease.

Spacetime algebraic skeleton [PDF]

open access: yes, 2002
The cosmological constant Lambda, which has seemingly dominated the primaeval Universe evolution and to which recent data attribute a significant present-time value, is shown to have an algebraic content: it is essentially an eigenvalue of a Casimir ...

Potential therapeutic targeting of BKCa channels in glioblastoma treatment

open access: yesMolecular Oncology, EarlyView.
This review summarizes current insights into the role of BKCa and mitoBKCa channels in glioblastoma biology, their potential classification as oncochannels, and the emerging pharmacological strategies targeting these channels, emphasizing the translational challenges in developing BKCa‐directed therapies for glioblastoma treatment.

Phosphate-dependent FGF23 secretion is modulated by PiT2/Slc20a2

open access: yesMolecular Metabolism, 2018
Objective: The canonical role of the bone-derived fibroblast growth factor 23 (Fgf23) is to regulate the serum inorganic phosphate (Pi) level. As part of a feedback loop, serum Pi levels control Fgf23 secretion through undefined mechanisms.

Skeleton as a probe of the cosmic web: the 2D case

open access: yes, 2003
We discuss the skeleton as a probe of the filamentary structures of a 2D random field. It can be defined for a smooth field as the ensemble of pairs of field lines departing from saddle points, initially aligned with the major axis of local curvature and

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

open access: yesMolecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Intelligibility of Post-War Reconstruction in French Bombed Cities

open access: yesUrban Planning, 2023
In the aftermath of the WWII, many French cities faced a great need for reconstruction in response to the heavy destruction caused by the bombardments.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

CT scan-based morphometric comparison of human and canine lumbar spine generates instrumental data for intervertebral disc percutaneous surgery

open access: yesOsteoarthritis and Cartilage Open
Objective: This study aimed to describe the anatomical landmarks for intervertebral disc (IVD) percutaneous approaches (transpedicular TPA and transannular TAA) using CT scans in humans and dogs for regenerative medicine research.
