Developing a Functional Polyelectrolyte Hybrid Layer Scaffold Coating and Evaluation of Its Performance for Interaction With Neural Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Polyelectrolyte scaffold coatings modified with Cu and Fe3O4 nanoparticles regulate neural stem cell behavior in vitro. Increased Fe3O4 content enhances mitochondrial activity and neuronal differentiation, whereas higher Cu levels reduce cell viability.

Histopathologic Changes in Dental Follicles: Are They Serious?

open access: yesDental Hypotheses, 2011
Pathologic changes within pericoronal tissues of impacted third molars are not uncommon. Retained impacted teeth within the bone may be associated with pathologic changes in pericoronal tissues due to unknown mechanisms.

Magnetic Droplet Manipulation on Open Surfaces

open access: yesAdvanced Materials Technologies, EarlyView.
Recent advances in the manipulation of magnetic droplets demonstrate various manipulations on open surfaces, including transport, splitting, merging, and force‐controlled motion, enabled by magnetic particles and external fields. ABSTRACT Manipulation of liquids on a smaller scale enables applications in various fields, particularly diagnostics and ...

Revealing the Transmission Hologram's Refractive Index Profile Stored in a Photohydrogel: A Structural Characterization

open access: yesAdvanced Optical Materials, EarlyView.
A theoretical model is developed to visualize three‐dimensional refractive index profiles in transmission holographic gratings. In this work, it is applied to photopolymerizable hydrogels, enabling detailed analysis of the internal structure of recorded holograms and their evolution under different degradation conditions.

A Self‐Healing Permanent Magnet Putty for Soft Robot Skins With Force Sensing and Functional Recovery

open access: yesAdvanced Robotics Research, EarlyView.
Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...

Tooth impaction: A new variable in difficulty index of third molar extraction

open access: yes, 2017
Third molar surgery is one of the major events carried out world-wide in a maxillofacial clinic. Preoperative assessment of surgical difficulty is fundamental to planning of extraction of impacted third molars.

Tailoring Vascular‐Immune Homeostasis via Manganese‐DNA Complex‐Armed Immunogenic Extracellular Vesicles for Pancreatic Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
This study demonstrates that Mn2⁺–tumor DNA complexes encapsulated in dendritic cell (DC)– derived immunogenic extracellular vesicles (EVDC@Mn‐DNA) act as a DC‐specific cGAS– STING activator. EVDC@Mn‐DNA treatment enhances intratumoral DC activation, improves tumor vascular function, promotes CD8⁺ T cell activity, and suppresses pancreatic tumor growth,

Pattern of mandibular third molar impaction in Ardabil population [PDF]

open access: yes
Objectives: Impacted third molar tooth (wisdom tooth) is a widespread phenomenon in which the third molar teeth don't fully erupt into the mouth because of blockage from other teeth that can cause damage to the adjacent teeth as well as the sorounding ...

QBP1 Peptide as a Potential Anti‐Amyloidogenic Therapy for Type 2 Diabetes: An In Vitro Study

open access: yesAdvanced Science, EarlyView.
The anti‐amyloidogenic peptide QBP1 effectively halts human islet amyloid polypeptide (hIAPP) aggregation, preventing the formation of toxic β‐structured intermediates. Through a combination of biophysical assays, molecular dynamics, and cell‐based studies, QBP1 is shown to preserve β‐cell viability and metabolic homeostasis, positioning it as a ...
