background: mesenchymal stem cells (msc) are a very promising transplantable stem cell source for a variety of cell replacement therapies. as the main source of msc is bone marrow (bm), most of studies have been done on bm-derived msc (bm-msc). umbilical cord (uc)-derived msc (uc-msc) which are recently introduced, is one of the good alternative source for these cells. the objective of this stu...

dear editor:   hehua ye and colleagues reported an interesting and rare case of primary conjunctival rhabdomyosarcoma (rms) successfully treated with surgery and chemotherapy in iranian journal of ophthalmology 201123(4):65-68. there are some considerable comments that i would like to point out.   orbital rms is the most common malignant mesenchymal neoplasm of the childhood and may also rarely...

leiomyoma is a very rare intraocular tumor, which can occur in the iris, ciliary body and choroids. we report a case of choroidal leiomyoma in a 16-years old women whose left eye was enucleated because of clinical suspicion for melanoma. using conventional light microscopy tumor was interpreted as spindle cell tumor, most probably of neurogenic origin and after using immunohistochemical studies...

Introduction: We did this study because there were a few studies about aorto-branch junction. Methods: Four light microscope and electron microscope study, the abdominal aorta, renal artery, and the adjoining right and left renal arteries were dissected out from 4 neonate dogs. Results: Based on the results, there is only one cell type in the tunica intima of endothelium in both art...

bunium persicum (boiss.) is an economically important medicinal plant growing wild in arid regions in iran. the essential oil of b. persicum (eobp) was extracted using hydrodistillation. a total of eighteen compounds, representing 96.14 % of the oil was identified by gas chromatography/mass spectrometry (gc/ms).the main compounds were cuminaldehyde (23.04 %), gamma-terpinene (14.48 %), trans-3-...

background and objectives: uterine smooth muscle tumors are the most common human neoplasm .they are divided clinically as benign and malignant but there is  another group of  lesions which is difficult to place in these two categories ,so-called smooth  muscle tumors of uncertain malignant potential (stump) and differentiation  of these tumors on the basis of h&e staining is impossible . t...

osteonectin is a bone- associated protein involved in vascular calcification. adiponectin may protect against cardiovascular disease but possible effects on vascular calcification have been poorly studied. the aim of this study was to investigate the modulatory effect of adiponectin on oxidized low density lipoprotein (oxldl)- induced expression of osteonectin in human aorta vascular smooth mus...
