A descriptive and morphometric study of the fabellofibular, arcuate popliteal and popliteofibular ligaments

Anatomy, 2015
Objectives:  The anatomical relationship of the fibrous structures in the posterolateral corner of the knee is highly complex, with many different descriptions of these structures in the literature. Discrepancy in the definitions of FF, AL and PF are a problem for both clinicians and anatomists. This study aimed to examine these structures and describe

Arginine Methylation Antagonizes TEAD3‐Mediated Repression to Promote Osteogenic Differentiation by Disrupting RUNX2‐Sequestrating Condensates

Advanced Science, EarlyView.
In the unmethylated state, TEAD forms stable, repressive condensates that sequester the osteogenic master regulator RUNX2. Arginine methylation of TEAD at R55 acts as a molecular brake, dissolving these condensates to release RUNX2 and activate the osteogenic program.

A guide to nestling development and aging in altricial passerines [PDF]

, 2007
Nestling growth and development studies have been a topic of interest for a greater part of the last century (Sutton 1935, Walkinshaw 1948) and continue to be of interest today. This is not surprising since studies on nestling growth can provide a wealth

Liver Stiffness Rises Early in MASLD and Drives Inflammation, Lipid Dysmetabolism, and Fibrosis via Piezo1–YAP Mechanotransduction

Advanced Science, EarlyView.
Progressive stiffening of the hepatic extracellular matrix and free fatty acid overload activate the mechanosensor Piezo1 in steatotic hepatocytes, inducing calcium influx and nuclear translocation of Yes‐associated protein. YAP‐dependent nuclear signaling further drives inflammatory and fibrotic gene programs, lipid metabolic reprogramming, and ...

Cellular Identity Crisis: RD3 Loss Fuels Plasticity and Immune Silence in Progressive Neuroblastoma

Advanced Science, EarlyView.
Researchers discovered that therapy‐induced loss of RD3 protein in neuroblastoma triggers a dangerous shift: cancer cells become more stem‐like, invasive, and resistant to treatment while evading immune detection. RD3 loss suppresses antigen presentation and boosts immune checkpoints, creating an immune‐silent environment.

Inactivation Rap2a in Endothelial Cell Prevents Pulmonary Fibrosis by Regulating Immune Microenvironment Through MAP4K4‐VCAM1 Signaling

Advanced Science, EarlyView.
We identified the endothelial RAP2A as a regulator of inflammatory endothelial activation in experimental lung fibrosis and suggest that targeting RAP2A‐mediated signaling may represent a potential strategy to modulate endothelial–immune crosstalk during fibrotic lung injury.

Real‐Time and High‐Resolution NIR‐II‐L Imaging of Netrin‐1‐Mediated Neurovascular Coupling Driven by Dose‐Dependent Electroacupuncture

Advanced Science, EarlyView.
Disrupted neurovascular coupling contributes to ovarian dysfunction in polycystic ovary syndrome. Using near‑infrared II long‑wavelength imaging, this study visualizes how electroacupuncture dynamically regulates ovarian blood vessels in vivo. Immediate and cumulative stimulation elicit distinct vascular responses via a Netrin‐1 dependent mechanism ...

Co‐Treatment With rhBMP‐2 and Rapamycin Modulates Osteogenesis–Adipogenesis Balance to Enhance Aged Bone Regeneration

Advanced Science, EarlyView.
This study demonstrates that the imbalance between osteogenic and adipogenic differentiation in senescent BMSCs, leading to excessive adipocyte accumulation, which subsequently impairs bone regeneration in aged mice. To address this pathological dysregulation, a novel energy‐supplying hydrogel system (PBR) has been developed to restore balanced ...

Single‐Cell Morphomechanics of Prostate Cancer‐Associated Fibroblasts Identifies Distinct Features Associated with Patient Outcome

Advanced Science, EarlyView.
Cancer‐associated fibroblasts (CAFs) in prostate tumors exhibit distinct morphomechanical traits vs normal fibroblasts, including greater stiffness and volume, more elongated stress fibres, and larger and more elongated nuclei. These features, quantified through imaging and real‐time deformability cytometry, correlate with patient outcomes and can be ...
