adenoid ameloblastoma with dentinoid is a rare odontogenic tumor. granular cell ameloblastoma also is a less common histological subtype of ameloblastoma. in this report, the patient was a 31‑year‑old male. the lesion was located in the right mandible and was unicystic with well‑defined borders. the tumor tissue was showing a combination of follicular, plexiform, and desmoplastic patterns of am...

granular cell tumor is a rare benign neoplasm most commonly appears in the head and neck region, especially in the tongue, cheek mucosa, and palate. occurrence in limbs is even rarer. these tumors account for approximately 0.5% of all soft tissue tumors. granular cell tumor can also affect other organs including skin, breast, and lungs. local recurrence and metastasis is potentially higher in m...

congenital epulis is a very rare benign soft-tissue tumor of uncertain histogenesis, which is also known as “gingival granular cell tumor of the newborn”. it occurs almost exclusively as a single tumor along the alveolar ridge of the maxilla in newborn females. although congenital epulis is strikingly similar to the more common adult granular cell tumor histologically, in contrast to the latter...

Snake robots can contact their environments along their whole bodies. This distributed contact makes them versatile and robust locomotors, but also makes controlling them a challenging problem involving high-dimensional configuration spaces, with no direct way to break their motion down into “driving” and “steering” actions. In this paper, we use concepts from geometric mechanics—e.g., expanded...

Background: Granular cell tumor (Abrikossoff’s tumor) is a rare and slow-growing tumor of the soft tissue. Originated from the Schwann cells, it is often a benign tumor, but it can be malignant in 1-3% of the cases. Malignant cases can cause significant morbidity and mortality. It may develop in many anatomic locations, especially in the head and neck region, and also in skin and subcutaneous t...

Strongly vertically shaken granular matter can display a density inversion: A high-density cluster of beads is elevated by a dilute gaslike layer of fast beads underneath ("granular Leidenfrost effect"). For even stronger shaking the granular Leidenfrost state becomes unstable and granular convection rolls emerge. This transition resembles the classical onset of convection in fluid heated from ...

endocrine therapy, a hysterectomy was deemed advisable. The abdomen was soft and relaxed; it was not tender and contained no palpable masses. At operation the uterus and appendix were removed and three globular tumors were discovered in the greater omentum and were excised. Exploration of the remainder of the peritoneal cavity revealed nothing unusual. Pathologic Emmination: The uterus and appe...

The ultrastructure of follicle cells has been compared to that of developing oocytes in the marine crustacean isopod, Idotea balthica basteri, at different periods of the molting cycle. There was a distinct change in the shape and size of the follicles and in their relation to each other and to the oocytes. During stage 1 of vitellogenesis (molting cycle period C), spaces between the follicles ...
