Captive breeding and rearing giant tortoises still represents a challenge and little scientific evidence is available on the requirements of juvenile and adult giant tortoises. Zoo veterinarians must know that developmental diseases are the main risk in the raising process. Respiratory tract disease, endoparasites and biting are other pathologic conditions that have been observed in juvenile gi...

1. Electrical stimuli delivered to the brain were used to activate the giant fibre of Drosophila. 2. The giant fibre drove a prominent wing opening movement. 3. Intracellular microelectrode recordings from direct wing opener muscle fibres showed that giant fibre activation of an anterior pleural muscle, pa3, was responsible for the wing opening movement. 4. The giant fibre drove a slight wing e...

INTRODUCTION Oral peripheral and central giant cell granulomas are lesions with little-known etiology and pathogenesis. OBJECTIVE The aim of this study was to compare matrix metalloproteinases-2 and osteopontin protein expression in the multinucleated giant cells and mononuclear cells of the peripheral and central giant cell granuloma lesions. METHODS In this retrospective study, the presen...

A primary giant cell tumor of the rib is very rare. The most common site of a giant cell tumor arising from the rib is the posterior arc. A giant cell tumor arising from the anterior arc of the rib is extremely rare. The treatment of a giant cell tumor of the rib is not well defined. Generally, a complete surgical resection is performed in a patient with a primary giant cell tumor of the rib. W...

Giant cell tumor is a locally aggressive benign tumor. Giant cell tumor of bone is characteristically found in skeletally mature patient at the end of long bones in the epiphyseal region or epiphysio-metaphyseal region. Giant cell tumor is very rare in skeletally immature patient. But we are presenting a very rare case of giant cell tumor in skeletally immature patient in diaphyseal region whic...

PURPOSE To determine whether giant vacuoles form preferentially near collector channels or over regions of optically empty space within the juxtacanalicular tissue (JCT). METHODS To assess the relationship between giant vacuoles and collector channels, six eyes were perfused with phosphate-buffered saline (PBS) at 20 mm Hg and then fixed by perfusion. Serial sections were cut in the frontal p...

Tomato (Lycopersicon esculentum Mill.) seedlings, susceptible (cv. Pearson A-I Improved) and resistant (cv. Pearson Improved) to race 1 Fusarium oxysporum f. sp. lycopersici (Sacc.) Snyd &Hans., were inoculated with Meloidogyne javanica (Trueb) Chitwood second-stage juveniles and 3 weeks later with race 1 F. oxysporum f. sp. lycopersici spores. One week after fungal inoculation, no fungus was v...

Giant cell tumor of soft parts is a rare tumor that is clinically and histologically similar to giant cell tumor of the bone. We present a 53-year-old female with a giant cell tumor of low malignant potential arising from the neck. The clinicopathological features and the importance of immunohistochemistry in the differential diagnosis with other giant cell rich tumors was discussed.

The total numbers of nuclei in giant cells induced by Meloidogyne incognita in pea, lettuce, tomato, and broad bean were determined. Mature giant cells from pea had the most nuclei per giant cell with a mean of 59 +/- 23, lettuce had the fewest with 26 +/- 16, and tomato and broad bean were intermediate. The rate of increase in numbers of nuclei for all plant species was greatest during the fir...

Osteoclast-like giant cell tumor of the pancreas is a rare non-endocrine neoplasm composed of reactive multinucleated giant cells admixed with mononuclear stromal cells. We report a case of osteoclast-like giant cell tumor of the pancreas in a 58-year-old female with vague clinical symptoms. Endoscopic ultrasound-guided aspirate from the mass revealed numerous characteristic osteoclast-like gia...
