Fractional order impedance models as rising tools for quantification of unconscious analgesia [PDF]

open access: yes, 2013
This research focuses on modeling the diffusion process that occurs in the human body when an analgesic drug is taken up, by using fractional-order impedance models (FOIMs).

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Placenta ingestion by rats enhances d- and k-opioid antinociception, but suppresses m-opioid antinociception [PDF]

open access: yes, 2004
Ingestion of placenta or amniotic fluid produces a dramatic enhancement of centrally mediated opioid antinociception in the rat. The present experiments investigated the role of each opioid receptor type (m, d, k) in the antinociception-modulating ...

Implantable Microarray Patch: Engineering at the Nano and Macro Scale for Sustained Therapeutic Release via Synthetic Biodegradable Polymers

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This review focuses on the application of synthetic biodegradable microarray patches (MAPs) in sustained drug delivery. Compared to conventional MAPs which release drugs into the skin in an immediate manner, these implantable MAPs release drugs into skin microcirculation gradually as the biodegradable polymers degrade, thus offering sustained release ...

Thermal Annealing Enhances Piezoelectricity and Regenerative Potential of PVDF‐TrFE Nanofiber Scaffolds

open access: yesAdvanced Materials Technologies, EarlyView.
Thermal annealing improves the structure, stiffness, and piezoelectric properties of poly(vinylidene flouride‐trifluoroethylene) (PVDF‐TrFE) nanofiber scaffolds. These annealed scaffolds promote Schwann cell proliferation and matrix remodeling in vitro and demonstrate in vivo biocompatibility.

In situ structure and assembly of the ABC-type tripartite pump MacAB-TolC

open access: yesCommunications Biology
The MacAB-TolC tripartite efflux pump is widely distributed in Gram-negative bacteria, extruding antibiotics and virulence factors that lead to multidrug resistance and pathogenicity.

Light Mediated Sulfonylation/C–H Activation/Annulation of Benzimidazoles Derivatives Catalyzed by Diarylmethylium Tetrafluoroborate Salts: An Experimental and Computational Study

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Through the exploiting of visible‐light, a key photoactive complex, and an acid‐catalyzed proton‐coupled electron transfer, polycyclic sulfonylated benzimidazoles are obtained through a domino process including sulfonylation, C–H activation, and annulation. Diarylmethylium tetrafluoroborates are employed as inexpensive organocatalyst capable of forming
