[18F]Fluorocholine PET/CT false positive: foreign body reaction mimicking anaplastic glioma progression. A case report

, 2023
Background Foreign body reaction in brain tissue is a very rare immune response that has not been well studied. Hemostatic material has been reported as a possible trigger of this response in other organs and could be detected by [18F]fluorodeoxyglucose ...

Noninvasive Focal Gene Delivery into the Cerebellum of Non‐Human Primates using Focused Ultrasound

Advanced Science, EarlyView.
Focal and non‐invasive viral vector delivery in non‐human primates remains a major challenge in translational neuroscience. Low‐intensity focused ultrasound was used to transiently open the blood–brain barrier and enable targeted gene delivery to the cerebellum.

Interface Wettability Transition‐Driven Drug Release and Dual‐Phase Functionalization in Implant Abutment

Advanced Science, EarlyView.
A temporally controlled drug release coating is developed for abutments using a superhydrophobic coating self‐assembled on mesoporous silica. This surface provides sequential functionality: initial contamination resistance through non‐wetting, followed by controlled drug release via wettability transition.

Sarcoid-like foreign body reaction in body piercing - a report of two cases [PDF]

, 1997
We report two cases of body piercing as a religious practice that subsequently led to the development of granulomatous nodules at previously punctured sites of the skin and oral mucosa.

Foreign body granulomatous reactions to cosmetic fillers

Journal of Clinical and Experimental Dentistry, 2012
The use of different facial cosmetic fillers has increased in recent years. The introduction of apparently inert substances in the epidermis can give rise to foreign body granulomatous reactions. Objetives: A literature review is made of the foreign body granulomatous reactions to cosmetic fillers.A PubMed-Medline search was made using the following ...

Organoid Brain‐Machine‐Interface Devices for Central Nervous System Repair

Advanced Science, EarlyView.
We envision organoid brain‐machine‐interface (Organoid‐BMI) devices as new biohybrid bidirectional communication pathways to connect the human CNS and the external world for personalized CNS repair and regeneration. ABSTRACT Central nervous system (CNS) repair and regeneration suffer from tremendous clinical challenges due to current limitations in ...

Systemic T-cell and local macrophage interactions mediate granule size-dependent biological hydroxyapatite foreign body reaction

Biological hydroxyapatite (BHA) has been widely used in alveolar bone augmentation, while unfavorable outcomes can still be encountered. Among several reasons, we noticed a chaotic granule size application issue. The principle behind the choice of proper

ZDHHC18‐Mediated Palmitoylation of ORF3a Promotes SARS‐CoV‐2 Pathogenesis by Antagonizing TRIM16‐Mediated Ubiquitination and Proteasomal Degradation

Advanced Science, EarlyView.
Palmitoylation by ZDHHC18 blocks ORF3a K27‐linked ubiquitination mediated by TRIM16, thereby preventing its proteasomal degradation and strengthening viral pathogenesis. Targeting palmitoylation through a pharmacological inhibitor (2‐BP), a competitive inhibitory peptide (OPIP), or adenovirus‐mediated knockdown of ZDHHC18 expression presents a ...
