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.

Parvalbumin Interneuron‐Dependent Hippocampal Neurogenesis Evoked by Prolonged Rhythmic Light Flicker

open access: yesAdvanced Science, EarlyView.
This study demonstrates that prolonged rhythmic 40 Hz light flicker enhances spatial learning by stimulating PV interneuron‐dependent neurogenesis. The light flicker selectively activates PV interneurons, which enhances GABAergic support for the integration of immature neurons in the adult dentate gyrus.

Proteomic approach used in the diagnosis of Riedel's thyroiditis: a case report

open access: yesJournal of Medical Case Reports, 2012
Introduction Riedel's thyroiditis, a rare thyroid disease, can be difficult to diagnose prior to surgical removal and can be confused with malignancy both clinically and cytologically. Case presentation We report the case of a 72-year-old Caucasian woman

Capturing the Electrical Activity of all Cortical Neurons: Are Solutions Within Reach?

open access: yesAdvanced Science, EarlyView.
Despite advancements in implantable electrode technology, challenges persist in scaling up these devices to record most of the neuronal activity across the cortex. This review explores the limitations of both rigid and flexible probes, including tissue damage and foreign body response, while also discussing emerging biohybrid strategies.

Engineered Anti‐Senescence Trachea With Post‐Transplanted Regenerative Homeostasis

open access: yesAdvanced Science, EarlyView.
Bioengineered trachea undergoes post‐transplanted senescence, which is found in this study for the first time. Hebe‐ET is designed with dual anti‐senescence strategies: fiber‐film scaffold in cartilage rings for close‐packed cell interaction, and quercetin‐loaded fibrous rings for immune modulation.

Fine-needle aspiration of the thyroid [PDF]

open access: yesCancer, 2000
Although fine-needle aspiration (FNA) of the thyroid is the key preoperative investigation of thyroid lesions, there are overlaps in the criteria for diagnosis of certain lesions, particularly important among which are those for follicular neoplasms.

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 ...
