A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation

Advanced Science, EarlyView.
A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.

Mr BMT Achieves Systemic Macrophage Replacement With Preservation of Tissue Homeostasis

Advanced Science, EarlyView.
Microglia replacement by bone marrow transplantation (Mr BMT) enables systemic replacement of tissue‐resident macrophages. Despite persistent macrophage and tissue remodeling across multiple organs, core biological functions and innate immune responses remain preserved, supporting long‐term maintenance of organismal homeostasis and the therapeutic ...

NeuroSuite for Long‐Term Functional and Structural Studies of Air‐Liquid Interface Cerebral Organoids

Advanced Science, EarlyView.
NeuroSuite provides a modular hardware‐software platform integrating Neuroweb and NeuroMaps to enable long‐term, in situ electrophysiological interrogation of air–liquid interface organoid slices while preserving tissue architecture. Its components can be used together or independently to capture real‐time activity, spatial network dynamics, and ...

Practical Direct Immunofluorescence

The American Journal of Dermatopathology, 2020
Abstract: Direct immunofluorescence (DIF) remains a valuable tool that may be underused because of perceived challenges in the interpretation, limitations, and processing of DIF specimens. The aim of this review is to provide a practical guide for appropriately incorporating DIF in a variety of clinical diseases, such as autoimmune blistering

Direct immunofluorescence in pyoderma gangrenosum

British Journal of Dermatology, 1983
Direct immunofluorescence was done in fifty-one cases of pyoderma gangrenosum. Biopsy specimens were taken from the peripheral erythematous zone of the lesion. In thirty-one cases (61%), there was positive immunofluorescence, with perivascular deposition of immune reactants being the most frequent pattern (twenty-seven cases).

Optimizing Direct Immunofluorescence

2014
Immunofluorescence is a laboratory technique that utilizes a fluorophore-labeled antibody to detect immune complexes in tissue. Most of the labeled antibodies used in a clinical laboratory bind the conserved domains within each class of human antibodies, allowing them to detect a wide range of autoimmune complexes.

Direct Immunofluorescence in the Diagnosis of Legionnaires' Disease

Chest, 1981
Over a 2 1/2 year period, 61 clinical specimens from 41 patients with pneumonia of uncertain etiology were evaluated for the presence of Legionella pneumophila (serogroups 1 to 4) by immunofluorescent antibody techniques. In 13 of 19 patients with Legionnaires' disease, the diagnosis was established by fluorescent antibody (FA) staining of lung ...

Granuloma annulare: direct immunofluorescence study

British Journal of Dermatology, 1976
Direct immunofluorescence studies were carried out in eleven specimens of granuloma annulare. The results (in all cases) indicate the presence of focal deposition of fibrin, localized primarily in the intervascular portion of the dermis, corresponding to the granulomatous and necrobiotic areas. These findings implicate the cellular mechanism of delayed

Candidiasis visualised by proteinase-directed immunofluorescence

Virchows Archiv A Pathological Anatomy and Histopathology, 1991
The secretory aspartic proteinases of Candida albicans and C. tropicalis are potential factors for virulence produced during infection. By indirect immunofluorescence, we have demonstrated proteinase antigen on elements of both species in deparaffinized tissue sections derived from clinical cases of mucosal and deep-seated candidiasis. Occasionally, we

Direct and indirect immunofluorescent findings in dermatomyositis

Journal of Cutaneous Pathology, 1985
Three skin biopsies (proximal nailfold, extensor forearm and buttock) and serum samples were studied by direct and indirect immunofluorescence, immunodiffusion and radioimmunoassay techniques in 6 patients with dermatomyositis. A variety of seroligic and immunopathologic abnormalities was observed in the patients.
