BDNF/TrkB Signaling in the Brain–Kidney Axis Under Functional Stress

Biology
Brain-derived neurotrophic factor (BDNF) and its high-affinity receptor tropomyosin receptor kinase B (TrkB) are classically associated with neuroplasticity, but increasing evidence suggests a broader role for BDNF/TrkB signaling in systemic stress ...

CD34+ Progenitors Promote Ageing‐Associated Valve Sclerosis through the PDGFR–JNK–JUNB Pathway

Advanced Science, EarlyView.
In age‐related aortic valve sclerosis, non‐bone marrow CD34+ progenitor valvular interstitial cells (VICs) undergo transdifferentiation into periostin+ myofibroblast‐like VICs via the PDGFR‐JNK‐JUNB axis, driving leaflet thickening and fibrosis. Ablating non‐bone marrow CD34+ cells attenuates this remodeling.

Matrix Stiffness Promotes Tumor Metastasis by Triggering Recycling Endosome‐Mediated YY1 Nuclear Translocation and Transcriptional Activity

Advanced Science, EarlyView.
In stiff extracellular matrix (ECM), integrin αVβ3 transduces mechanical cues of ECM stiffness to promote recycling endosome formation, creating a signaling platform for yin yang 1 (YY1)/p21‐activated kinase 4 (PAK4) binding, but not in soft ECM. Then, this triggers PAK4‐mediated YY1 phosphorylation at S118, subsequent YY1 nuclear translocation and ...

Validating electrical stimulation through the somatosensory system: a perspective on mismatch negativity and auditory prostheses

Frontiers in Human Neuroscience
Natural touch engages specialized mechanoreceptors, while electrotactile stimulation bypasses them, directly depolarizing a mixed and non-uniform population of afferent axons.

Solution‐Shearing of Highly Smooth Ion‐Gel Thin Films: Facilitating the Deposition of Organic Semiconductors for Ion‐Gated Organic Field Effect Transistors

Advanced Electronic Materials, Volume 11, Issue 6, May 2025.
A straightforward method is introduced to produce ion‐gel films with very low surface roughness by employing a solution‐shearing coating process. These ion‐gel films permit the growth of crystalline thin films of various small molecule organic semiconductor molecules directly on top of the ion‐gel layer, thereby enabling “inverted” small molecule ...

Diol Chain‐Length Effects in Adipate and Succinate Polyesters for Thermoplastic Polyurethanes

Journal of Applied Polymer Science, EarlyView.
This study examines 20 aliphatic polyesters as soft segments for thermoplastic polyurethanes (TPU), synthesized from adipic or succinic acid and diols (C2, C3, C4, C5, and C6). A pronounced odd‐even effect shows that even diols crystallize, while odd diols remain amorphous.

Ocular morphology and morphometry of the great egret (Ardea alba): A comprehensive anatomical description

The Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is widely distributed, yet knowledge of its ocular morphology remains limited. This study described the morphometry and morphology of the eyeball and its accessory glands in six specimens using radiography, morphometry, light and scanning electron microscopy, and 3D scanning.
