Effect of Bronchial Brush Size on Cell Recovery
American Review of Respiratory Disease, 1987The effect of bronchial brush size on cell recovery during fiberoptic bronchoscopy was investigated. In 20 patients undergoing diagnostic bronchoscopy, 3 additional brushings in normal peripheral airways were performed using sheathed brushes of 1.0, 1.73, and 3.0 mm in diameter.

PREVENTING MALIGNANT-CELL TRANSFER DURING ENDOSCOPIC BRUSH CYTOLOGY
The Lancet, 1979Transfer of malignant cells on cytology brushes was responsible for false positive cytology reports in 4 patients. In 24 examinations of cytology brushes after patients with gastric carcinoma had been previously endoscoped, malignant cells were identified on 7 occasions.

Radiation changes in endocervical cells in brush specimens
Diagnostic Cytopathology, 1990AbstractAlthough the cytologic changes in cervical and vaginal squamous cells after radiation therapy were well‐described decades ago, alterations in endocervical cells in response to radiation therapy have not been delineated in detail. We studied the effect of radiation therapy (usually combined linear accelerator beam and radium insertion) on ...

Whole-cell chloride conductances in cultured brushed human nasal epithelial cells
Canadian Journal of Physiology and Pharmacology, 1992Human airway epithelial cells were obtained by nasal brushing, thus avoiding the use of proteolytic enzymes for cell isolation. Whole-cell Cl− conductances were studied in these cells by means of the patch-clamp technique. During whole-cell recordings, cell swelling activated a Cl− conductance that was blocked by indanyloxyacetic acid (48 ± 10 ...

Morphological characterization of brush cells in the rat trachea
Tissue and Cell, 2020Brush cells have recently been classified as solitary chemosensory cells. However, tracheal brush cells have not been morphologically and immunohistochemically characterized yet. In the present study, the morphological and immunohistochemical characteristics of tracheal brush cells were analyzed using immunohistochemistry and scanning, and transmission

Thermoresponsive anionic copolymer brush-grafted surfaces for cell separation
Colloids and Surfaces B: Biointerfaces, 2020Cell separation methods that do not require surface modification of cells are needed in tissue engineering and regenerative medicine. We developed thermoresponsive anionic polymer brushes for cell separation without modification of the cell surfaces. Copolymer brush poly(N-isopropylacrylamide-co-N-tert-butylacrylamide-co-tert-butyl acrylate, P(NIPAAm ...

An Improved Method of Cell Recovery following Bronchial Brushing
Chest, 1988Cytologic examination of bronchial brush specimens is effective in diagnosing bronchogenic carcinoma. A major problem is loss of cells and cellular detail associated with the direct smear technique (DST). A more recent method, the Saccomanno brush wash (SBW), uses a narrow-mouthed vial to scrape cells off the brush directly into fixative. We sampled 12

Munoz (1990) described monodendritic neurons in the human cerebellar cortex using chromogranin A-like immunoreactivity. Mugnaini and Floris (1994), Mugnaini, Floris, and Wright-Gross (1994), Mugnaini, Dino, and Jaarsma (1997) with antibodies to calretinin and neurofilament proteins characterized similar cells which they termed unipolar brush cells (UBC)

Differential distribution of brush cells in the rat lung
The Anatomical Record, 1986AbstractThe distribution of brush cells in the rat lung was studied using electron microscopic morphometry. Samples were taken from six distinctive anatomical regions. Tissue from the trachea, lobar bronchi, terminal bronchioles, first alveolar duct bifurcations, proximal alveolar regions, and the distal alveolar region were isolated and embedded in ...

Thermoresponsive Cationic Copolymer Brushes for Mesenchymal Stem Cell Separation
Biomacromolecules, 2015Thermoresponsive, cationic, copolymer brushes poly(N-isopropylacrylamide(IPAAm)-co-N,N-dimethylaminopropylacrylamide-co-N-tert-butylacrylamide(tBAAm)) and poly(IPAAm-co-3-acrylamidopropyl trimethylammonium chloride-co-tBAAm) were prepared on glass substrates through surface-initiated atom transfer radical polymerization. Prepared copolymer brushes were
