The time course of morphological changes during lysis of Escherichia coli cells was examined with respect to an undisturbed release of nucleoids. The addition of detergents to plasmolyzed, osmotic sensitive cells resulted in the immediate reversal of plasmolysis followed by the appearance of rod-shaped ghost cells without any detectable spheroplast formation. Electron microscopic examination of...

Chloroviruses infect their hosts by specifically binding to and degrading the cell wall of their algal hosts at the site of attachment, using an intrinsic digesting enzyme(s). Chlorovirus PBCV-1 stored as a lysate survived longer than virus alone, suggesting virus attachment to cellular debris may be reversible. Ghost cells (algal cells extracted with methanol) were used as a model to study rev...

Dentinogenic ghost cell tumor (DGCT) is an uncommon locally invasive odontogenic tumor regarded by many as a variant of calcifying odontogenic cyst. The peripheral variant of this clinical rarity appears as a well-circumscribed mass mimicking a nonspecific gingival enlargement. Microscopic appearance of odontogenic epithelium admixed with focal areas of dentinoid formation and sheets of ghost c...

Introduction: Ghost cell glaucoma (GCG) is a very rare secondary open angle glaucoma, in which there sustained increase intraocular pressure (IOP) due to obstruction of the trabecular meshwork (TM) passage ghost cells (GC) from vitreous into anterior chamber, after hemorrhage (VH). Clinical Case: We present case male patient with history and IOP elevation right eye (RE). Medical treatment was i...

BACKGROUND AND AIM Researchers have demonstrated dead cells in radiofrequency ablation (RFA) lesions that have morphological similarities to viable tumor cells and are thus referred to as ghost cells. However, studies on how long ghost cells persist have not been systematically performed. METHODS A tumor model was established by implanting VX2 tumor tissue into the livers of 48 New Zealand ra...

Calcifying epithelial odontogenic tumors (CEOTs) and ghost cell odontogenic tumors (GCOTs) are characteristic odontogenic origin epithelial tumors which produce calcifying materials from transformed epithelial tumor cells. CEOT is a benign odontogenic tumor composed of polygonal epithelial tumor cells that show retrogressive calcific changes, amyloid-like deposition, and clear cytoplasm. Differ...

Ghost cell odontogenic carcinoma (GCOC) is an extremely rare that typically characterized by admixture of atypical epithelial cells and ghost cells. Up to date, GCOC remains with around 58 cases have been reported. Herein,we report a case the mandible, patient particularly young, successfully treated surgical resection, reconstruction, radiation, followed for 2 years without any sign recurrence...
