A four-year-old male Persian cat was referred with three weeks history of progressive lameness due to a rigid osseous mass with 3.50×2.50×2.00 cm in dimensions in his left arm. In the histopathological evaluation of bone biopsy, two distinct populations of cells including multinucleated giant cells and oval cells which embedded in a fibro-osseous stroma and surrounded by lamellar bone trabecula...

  Primary sarcomas of the kidney are exceptional. Among renal sarcomas, leiomyosarcoma is the most common histologic subtype amounting to 50-60% of all cases. The tumor usually arises from either the renal capsule or smooth muscle tissue in the renal pelvic wall. In this paper, we report a patient with leiomyosarcoma of the kidney presented with non-specific abdominal pain and a palpable mass....

Abstract Background Muscle is severely affected by ischemia/reperfusion injury (IRI). Quiescent satellite cells differentiating into myogenic progenitor (MPC) possess a remarkable regenerative potential. We herein established model of local application MPC in murine hindlimb to study cell engraftment and differentiation required for muscle regeneration. Methods A clamping (C57b/6 J) ischemia wa...

Urothelial bladder cancer is the tenth most common worldwide. It divided into muscle and non-muscle invading cancer. Primary cilia have been related to several hallmarks such as proliferation, epithelial-to-mesenchymal transition (EMT) or tumoral progression mainly through signaling pathways Hedgehog (Hh). In present study, we used immunohistochemical ultrastructural techniques in human tissues...

hedera helix  is widely used to treat bronchial asthma for many years. however, effects of this herb on lung histopathology is still far from clear. we aimed to determine the effect of oral administration of hedera helix on lung histopathology in a murine model of chronic asthma. balb/c  mice  were  divided  into  four  groups;   i  (placebo),  ii  (hedera  helix), iii (dexamethasone) and iv (c...
