Periacinar clefting and p63 immunostaining in prostatic intraepithelial neoplasia and prostatic carcinoma [PDF]

open access: yes, 2006
The aim of the present study was to correlate the presence and extent of retraction clefting and the expression of p63 in neoplastic glands and glands with prostatic intraepithelial neoplasia (PIN) in needle core biopsies.

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

Interactions Between Active Matters and Endogenous Fields

open access: yesAdvanced Materials, EarlyView.
This review synthesizes endogenous field information and computational methods in contexts such as cancer, wounds, and biofilms. It organizes NAMs and AAMs by sensing, transmitting, and executing functions, compares their limitations, and from these contrasts proposes design strategies for next‐generation AAMs, offering perspectives to foster ...

Fine-needle aspiration biopsy: its Use in orbital tumors [PDF]

open access: yes, 1979
Fifteen orbital tumors have been evaluated with the fine-needle aspiration biopsy (FNAB) technique. The best indication for FNAB is supposed malignant orbital disease.

PiP‐Plex: A Particle‐in‐Particle System for Multiplexed Quantification of Proteins Secreted by Single Cells

open access: yesAdvanced Materials, EarlyView.
Detecting proteins secreted by a single cell while retaining its viability remains challenging. A particles‐in‐particle (PiPs) system made by co‐encapsulating barcoded microparticles (BMPs) with a single cell inside an alginate hydrogel particle is introduced.

Ultrasonic needles for bone biopsy [PDF]

open access: yes, 2017
Bone biopsy is an invasive clinical procedure where a bone sample is recovered for analysis during the diagnosis of a medical condition. When the architecture of the bone tissue is required to be preserved, a core-needle biopsy is taken.

Microneedles From Shape‐Preserving Crosslinked Poly(Vinyl Alcohol) Hydrogels: Minimising Interference in Transdermal Proteomics

open access: yesAdvanced Materials Technologies, EarlyView.
Hydrogel‐forming microneedle patches are developed using shape‐preserving PVA‐PVP hydrogels, with and without chitosan, for minimally invasive transdermal protein biomarker sampling. The optimised patches enable efficient interstitial fluid uptake and proteomic analysis, while minimising interference.

Piezoelectric needle sensor reveals mechanical heterogeneity in human thyroid tissue lesions. [PDF]

open access: yes, 2019
Palpable thyroid lesions are common, and although mostly benign, lethal malignant nodules do occur and may be difficult to differentiate. Here, we introduce the use of a piezoelectric system called Smart-touch fine needle (or STFN) mounted directly onto ...

Wireless Capsule Device for Targeted and Safe Tissue Biopsy with Integrated Sensing

open access: yesAdvanced Materials Technologies, EarlyView.
This work presents a capsule device featuring a novel magnetically controlled biopsy mechanism for enhanced safety. The biopsy unit integrates a foldable linkage with dual magnets, creating a magnetic attraction–based safeguard, preventing unintended activation during locomotion. A flexible sensor provides real‐time penetration displacement sensing for
