Prion diseases are induced by pathologically misfolded prion protein (PrPSc), which recruit normal sialoglycoprotein PrPC by a template-directed process. In this study, we investigated the expression of PrPC in a rat model of cerebral ischemia to more fully understand its physiological role. Immunohistochemical analysis demonstrated that PrPC-immunoreactive(More)
Neuroplasticity subsequent to functional angiogenesis is an important goal for cell-based therapy of ischemic neural tissues. At present, the cellular and molecular mechanisms involved are still not well understood. In this study, we isolated mesenchymal stem cells (MSCs) from Wharton's jelly (WJ) to obtain clonally expanded human umbilical cord-derived(More)
It is unknown whether human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) can improve the renal function of patients suffering from acute kidney injury. Moreover, before beginning clinical trials, it is necessary to investigate this renoprotective effect of hUC-MSCs in a xenogeneic model of acute kidney injury. However, no previous studies have(More)
Although donor age-related effects of characteristics of mesenchymal stem cells (MSC), such as a decrease in the proliferation and differentiation capacity and an increase of senescence and apoptosis, are evident, such effects are generally less prominent in adipose-derived stem cells (ASC). Using a hormone and growth factor rich medium (KFSM), this study(More)
OBJECTIVES To study the surgical morbidity associated with laparoscopic management of tubal ectopic pregnancy compared with that of open laparotomy. METHODS A retrospective study in an academic tertiary obstetrics and gynecology referral center was conducted from 2005 through 2007. Forty-nine patients who had pathology-confirmed tubal ectopic pregnancies(More)
Epigenetic remodeling of cell adhesion genes is a common phenomenon in cancer invasion. This study aims to investigate global methylation of cell adhesion genes in cervical carcinogenesis and to apply them in early detection of cancer from cervical scraping. Genome-wide methylation array was performed on an investigation cohort, including 16 cervical(More)
The origin of the majority of epithelial ovarian cancers (EOC) is regarded as extraovarian, with the ovary being the secondary site. The aim of this study was to explore the possible role of ovarian mesenchymal stem cells (OvMSCs) and secreted IL-6 in the development of EOC. OvMSCs were derived from normal ovarian stroma. Cell surface markers and(More)
During human ovulation, the fallopian tube fimbriae must move to the ovulation site to catch the oocyte. As the tissue-of-origin of the majority of ovarian high-grade serous carcinoma (HGSC), the fallopian tube fimbriae carrying a precursor cancer lesion may also approach the ovulatory site for metastasis. We hypothesize that platelet-derived growth factor(More)
OBJECTIVES Isolated torsion of the fallopian tube is an uncommon cause of acute lower abdominal pain. It is often found in reproductive-age women and is found less in prepubertal and perimenopausal women. METHODS We describe a 70-year-old postmenopausal woman who presented with lower abdominal pain and discomfort. Ultrasonography revealed a well-defined,(More)
