The cellular responses induced by Meloidogyne arenaria races 1 and 2 in three soybean genotypes, susceptible CNS, resistant Jackson, and resistant PI 200538, were examined by light microscopy 20 days after inoculation. Differences in giant-cell development were greater between races than among the soybean genotypes. M. arenaria race 1 stimulated small, poorly formed giant-cells in contrast with...
Basal cell carcinoma (BCC) is the most common cutaneous malignancy and the most common human malignancy in general. Out of all basal cell carcinomas, giant basal cell carcinoma represents less than 1%. Only 10% of all basal cell carcinomas are located on the trunk and majority is located on the head and neck. We describe a patient with a exophytic giant basal cell carcinoma of the back size 8.5...
Multinucleated giant cells are an important feature of the granulomatous reaction in Crohn's disease (CD) but their cellular origin is poorly understood. The aim of this study was to discover if intestinal macrophages are capable of generating multinucleated giant cells in vitro in response to cytokine stimulation. Human intestinal macrophages were isolated from the intestinal mucosa of CD and ...
Abstract Background: Resection of the distal end of the radius is indicated in the treatment of locally aggressive primary benign and malignant bone tumors. The aim of this study was to evaluate the technique of osteoarticular allograft reconstruction of the distal radius after wide excision of a giant-cell tumor. Methods: We analyzed 15 patients retrospectively who had reconstruction of t...
تحقیقات مختلف اثبات نموده اند که رشد و محتوای بیوشیمیایی روتیفرها می تواند تحت تاثیر نوع غذا و غلظت مواد غذایی تغییر نماید. ریز جلبک ها به عنوان یکی از منابع غذایی مهم برای کشت روتیفرها به ویژه از لحاظ شاخص های نظیر رشد، بقا، میزان پروتئین، چربی و اسیدهای چرب، ضروری می باشند. لذا تحقیق حاضر جهت مقایسه جلبک خشک (کلرلای پودری) و جلبک های تازه (ایزوکرایسیس گالبانا و نانوکلروپسیس آکولاتا) بر رشد، ت...
Giant-cell tumours of bone were probably first described by Cooper and Travers in 1818. N#{233}laton (1860) designated them “ tumeurs a myeloplaxes.” The name giant-cell tumour was introduced by Bloodgood (1919). Stewart (1922) regarded the giant cells as an integral part Of the growth and believed that they were related to the osteoclasts of normal bone; he proposed the term osteoclast sarcoma...
Giant cell arteritis (GCA) is the most common vasculitis of the elderly. The diagnosis can be challenging at times because of the limitation of the American Rheumatology Association (ARA) classification criteria and the significant proportion of biopsy-negative patients with GCA. We discuss the role of advanced imaging techniques, including positron emission tomography (PET) scanning, in establ...
BACKGROUND Osteoclast-like giant cell tumors are usually observed in osseous tissue or as tumors of tendon sheath, characterized by the presence of multinucleated giant cells and mononuclear stromal cells. It has been reported in various extraosseous sites including breast, skin, soft tissue, salivary glands, lung, pancreas, female genital tract, thyroid, larynx and heart. However, extraosseous...
Aims: To examine the expression of ADAM12 (meltrin α), a member of the disintegrin and metalloprotease (ADAM) family, in human giant cell tumours of the bone, skeletal muscle tissue from human embryos, and human adult skeletal muscle tissue. Methods: ADAM12 mRNA was detected by reverse transcription polymerase chain reaction and in situ hybridisation. Results: ADAM12 mRNA was detected in 14 of ...
