myelography is a diagnostic procedure to indicate spinal defects. after the inception of new means of spinal cord imaging, use of myelography has been limited. since there are contraindications for other modalities in some patients, we have to use myelography. the most common complication of myelography is post myelography headache (pmh). many methods have been proposed to alleviate the pain. i...

Recently an ancient pathway in transplantation was accidentally retrod when a malignant tumor that was undiagnosed in the lifetime of a cadaveric multiple organ donor was transplanted to several recipients of various organs. The following is an account of the subsequent tragic events. Case Report. A 36-year-old woman died of an apparent spontaneous cerebral hemorrhage. Her past medical history ...

Background: Galectin, an animal lectin that recognizes b-galactosides of glycoconjugates, is involved in multiple biological functions such as cell growth, differentiation, apoptosis, signal transduction and angiogenesis. Overexpression of galectin-3 was observed in different tumors which was related to pro-angiogenic activity. In addition, galectin-3 is intensely expressed in corpus luteum (CL...

Background Xenotransplantation of ovary can help individuals who may be at sterility risk after chemotherapy or radiotherapy of diseases such as cancer. Moreover, this technique can be used to preserve fertility of valuable animal species. The aim of the present study was to preserve balb/c mice ovarian tissue by xenotransplantation into uterus of rat that is immune suppressed. MaterialsAndMeth...

It has been generally accepted for more than half a century that, in most mammalian species, oocytes cannot renew themselves in postnatal or adult life, and that the number of oocytes is already fixed in fetal or neonatal ovaries. This assumption, however, has been challenged over the past decade. In this study, we have taken an endogenous genetic approach to this question and generated a multi...

The gonads, both ovaries and testes, of 44 elephant fetuses weighing 0.09-112 kg (6.1-21.3 months gestation) were examined grossly and histologically. As in equids, elephant fetal gonads undergo a phase of marked growth and enlargement during the second half of gestation, which is more pronounced in ovaries than testes due to growth and antrum formation of numerous follicles in the former. Stro...

the aim of this investigation was to study macroscopic and microscopic structures of ovaries in barbus grypus of karoon river and their changes during annual maturation cycle. for this purpose, 120 adult  b.grypus with a mean weight of 835.0 to 1012.0 g, were caught from karoon river and transferred alive to the laboratory. after biometrical studies, the weights and morphological appearances of...

Background: The development of a reliable method for the cryopreservation of mammalian ovary would be an important advancement in the field of reproductive biology for the preservation of genetic resources. The cryopreserved follicles have the potential to develop in-vitro; however, the developmental rate is lower than that of fresh follicles. Researchers have used that of different cryoprotect...

lumbar puncture (lp) is a procedure for obtaining spinal fluid from spinal meningeal spaces this can be done as a diagnostic or therapeutic procedure which can result in to a typical positional headache named as post lumbar puncture headache .this can cause a lot of discomforts for patients and makes fear from the procedure. this study designed to evaluate the effect of resting position after l...
