Macroscopic and microscopic characteristics of 210 spontaneous ovarian tumors from 7748 Sprague-Dawley rats are described. The tumors were classified as tubular adenoma, anaplastic adenocarcinoma, papillary cystadenoma, papillary cystadenocarcinoma, mesothelioma, sertoliform tubular adenoma, Sertoli's cell tumor, granulosa cell tumor, thecal cell tumor, polycystic sex cord/stromal tumor, and li...

BACKGROUND A postoperative magnetic resonance imaging (MRI) is performed as a routine to assess decompression of the spinal cord as well as to evaluate postoperative complications. The purpose of this study is to analyze the efficacy of postoperative MRI for hematoma in spinal decompression surgery. METHODS Between January 1, 2008 and January 31, 2015, 185 patients who underwent postoperative...

We examined a free-living Symbiodinium species by light and electron microscopy and nuclear-encoded partial LSU rDNA sequence data. The strain was isolated from a net plankton sample collected in near-shore waters at Tenerife, the Canary Islands. Comparing the thecal plate tabulation of the free-living Symbiodinium to that of S. microadriaticum Freud., it became clear that a few but significant...

The authors present distinctive computed tomographic (CT) findings in two cases of long-standing ankylosing spondylitis accompanied by the cauda equina syndrome. Multiple, asymmetric erosions of the posterior elements of the lumbar spine on CT were correlated with thecal diverticula demonstrated by myelography. The pathogenesis of these erosions may be related to arachnoiditis in the early phas...

BACKGROUND Recently, several members of the transforming growth factor-beta (TGF-beta) superfamily have been shown to be essential for regulating the growth and differentiation of ovarian follicles and thus fertility. METHODS Ovaries of neonatal and adult sheep were examined for expression of the TGF-betas 1-3 and their receptors (RI and RII) by in situ hybridization using ovine cDNAs. The ef...

Objectives of this study were to determine if concentrations of steroids, insulin-like growth factor-I (IGF-I) and IGF-II in follicular fluid, and numbers of LH and IGF-I receptors change during growth of the dominant follicle. Ovarian follicular development was monitored daily via ultrasound in lactating Holstein cows. Animals were bilaterally ovariectomized when the dominant follicle (DF) was...

Angiogenic factors are associated with angiogenesis during follicular development in the mammalian ovary. The aim of the present study was to determine the relationships between the vascular network and mRNA expressions of angiopoietins (Ang)-1, Ang-2 and hepatocyte growth factor (HGF), and their receptors in follicles at different developmental stages during follicular development. Ovaries in ...

I HE advent of chemotherapy has forced physicians and surgeons to change their views on the prognosis and treatment of many injuries and diseases. The greatly improved results following the introduction of the sulphonamides has been further advanced by the discovery and use of penicillin. Previously, surgery's main ftunction in many cases of infection was to provide drainiage, leaving the defen...

Schwann cell (SC) transplantation is currently being discussed as a strategy that may promote functional recovery in patients with multiple sclerosis (MS) and other inflammatory demyelinating diseases of the central nervous system (CNS). However this assumes they will not only survive but also remyelinate demyelinated axons in the chronically inflamed CNS. To address this question we investigat...
