Respiratory motion is a major obstacle in radiation therapy of thoracic and abdominal tumors. Techniques to cope with it such as gating and tracking techniques are based on the use of breathing signals that can be acquired easily and in real-time. These signals represent only surrogates of the motion of the inner organs and tumors. Consequently, methods are needed to estimate respiratory motion...

Fat-associated lymphoid clusters (FALCs) are novel tissues that have been reported in the mesenteric and mediastinal fat tissue of mouse human. It plays role progression respiratory intestinal inflammation parasitic infestations. However, their occurrence chicken air sacs adipose has not yet identified. Here we investigated distribution FALCs (cervical, clavicular, thoracic, abdominal) healthy ...

To test the transforming potential of deregulated P40/Interleukin 9 expression, we transfected a mouse P40-dependent T cell line with P40 cDNA, and examined the tumorigenicity of the resulting transfectants. When the cells, which grew autonomously in vitro, were injected intraperitoneally or subcutaneously into syngeneic mice, a very high tumor incidence was observed with as few as 10(4) cells ...

Descending thoracic aorta to femoral bypass graft is an alternative procedure for revascularization of the lower extremities to conventional techniques, when the abdominal aorta is complete obstructed. In general, this technique is performed by surgeons, when abdomen is unable to be opened due to the presence of an abdominal infection, fistulas, or hostile abdomen. In this article, we present o...

introduction paragangliomas are mostly localized in the adrenal medulla and they are usually pheochromocytomas, derived from the neural crest, but otherwise mesenteric paragangliomas are extremely rare tumors. case presentation in this article we represent a 59-year-old female with an abdominal mass and pain due to mesenteric paraganglioma. conclusions paragangliomas can occur as mesenteric tum...

OBJECTIVE Perivascular adipose tissue depots around the aorta are regionally distinct and have specific functional properties. Thoracic aorta perivascular adipose tissue (tPVAT) expresses higher levels of thermogenic genes and lower levels of inflammatory genes than abdominal aorta perivascular adipose tissue (aPVAT). It is not known whether this distinction is due to the in-vivo functional env...

Lymphomatous involvement of the appendix is rare and most of them are found accidentally from appendectomies to treat appendicitis. Here we report three cases of primary lymphoma of appendix of 10 year-old boy, 23-year-old man and 24-year-old woman that presented with abdominal pain to our hospital and the tumors were discovered during routine appendectomy for suspected "appendicitis". Our case...

Esophageal perforation continues to be a difficult diagnostic and management problem. Recommendations regarding treatment remain controversial. 17 patients with perforation of the esophagus were retrospectively reviewed at the Thoracic Surgery Unit of Imam Khomeini Hospital between 1981 and 1992. The majority of the injuries involved the thoracic esophagus (10 or 59%), followed by the cerv...

By TALBERT COOPER, M.D., AND CHARLES H. WATKINS, M.D. T HE DIAGNOSIS of malignant lymphoma can be definitely established only by histologic examination of the tissue involved. In the majority of instances palpably enlarged superficial lymph nodes are present and properly performed biopsy provides the correct diagnosis in a direct and relatively simple manner. However, in a significant number of...
