Unveiling the Fundamental Principles of Reconfigurable Resistance States in Silver/Poly(Ethylene Glycol) Nanofluids

open access: yesAdvanced Science, EarlyView.
The electrophoretic reorganization of Ag nanoparticles within a poly(ethylene glycol) leads to the formation of conductive bridges with reconfigurable resistance states. Diverse conduction characteristics of the bridge range between ohmic conduction, nonlinear tunneling, or space charge‐limited conduction, and high resistance states.

FGF9–FGFR2 Signaling via Osteocytes‐Preosteoblasts Crosstalks to Mediate Mechanotransduction‐Driven Intramembranous Osteogenesis in the Underdeveloped Maxilla

open access: yesAdvanced Science, EarlyView.
This study identifies osteocyte‐derived FGF9 as a mechanosensitive factor that impairs osteogenesis in the underdeveloped maxilla by inducing FGFR2 nuclear translocation in preosteoblasts. Mechanical stimulation reduces FGF9 secretion, relieving its inhibitory effect. These findings reveal a novel osteocyte–preosteoblast FGF9–FGFR2 axis in craniofacial

Near‐Infrared‐Responsive Digital PCR‐Assisted Renal Cancer Exosomal miRNAs Insights and Regulation of Macrophage Polarization

open access: yesAdvanced Science, EarlyView.
A near‐infrared‐responsive digital Polymerase Chain Reaction technique with triple‐color coding profiles renal cancer exosomal microRNA biomarkers and their impact on macrophage polarization. Engineered miR‐34‐loaded exosomes via electroporation saturate molecular sponges, downregulating STAT3 in recipient macrophages to prolong M2 polarization. Stable

From Knitting Technology to Robotics: Untethered Thermally Actuated Textile Exoskeleton for Dexterity Applications

open access: yesAdvanced Science, EarlyView.
A textile‐based exoskeleton glove with integrated thermally driven actuators achieves rapid, low‐power response for dexterous motion. Utilizing advanced knitting methods, embedded heaters, and hybrid yarn sensors, the glove bends in a segmented fashion under 12 s at only 10.8 W and 48 °C.

Sebaceous Carcinoma – Unexpected Tumor of the Nasal Ala Dorsum

open access: yesActa Medica Bulgarica, 2019
Today, the extraocular variant of sebaceous carcinoma is still being poorly recognized. This type of carcinoma is rarely diagnosed correctly, which, together with its aggressive behavior, contributes to its poor prognosis. We present a case of an 84-year-
