OBJECTIVE To evaluate the feasibility of contralateral autotransplantation of cryopreserved whole ovaries with microanastomosis of the ovarian vascular pedicle. DESIGN Animal study. SETTING Department of Biomedical Sciences, General Hospital of Vienna, Austria. ANIMAL(S) Nine ewes, six month of age. INTERVENTION(S) Laparotomic unilateral(More)
Purpose: To evaluate whether a total ovary can successfully be cryopreserved and thawed under maintenance of high proportions of structurally normal primordial follicles. Methods: Porcine ovaries were explanted immediately after slaughtery. Ten ovaries were cooled to −196°C using cryoprotective solution and a computer-controlled freezing technique. Five(More)
OBJECTIVE To critically review our experience with the method of laparoscopic ovarian tissue harvesting for ovarian cryopreservation. STUDY DESIGN In a retrospective cohort study 85 patients undergoing surgery for cryopreservation of ovarian tissue were included. One random ovarian cortical slice was histologically examined in order to determine the(More)
OBJECTIVE To evaluate the efficacy of vesical instillation of hyaluronic acid against recurrent urinary tract infections. METHODS Twenty women with a history of recurrent urinary tract infections each received 9 intravesical instillations of hyaluronic acid over 6 months. Their status was assessed prospectively over 47.6 weeks and compared with a(More)
OBJECTIVE To evaluate the effects of a non-prescription red clover extract (MF11 RCE, Melbrosin International, Vienna, Austria) on selected sex hormones and endometrium in postmenopausal women. PATIENTS AND METHODS One-hundred and nine postmenopausal women with an age > or =40 years were randomly assigned to one of two groups either two capsules of(More)
OBJECTIVE To evaluate the effect of isoflavones derived from red clover extracts (MF11RCE) over anxiety and depressive symptoms among postmenopausal women. METHODS One hundred and nine postmenopausal women aged 40 or more were randomly assigned to receive two daily capsules of MF11RCE (80mg red clover isoflavones, Group A) or placebo of equal appearance(More)
Relatively little is known about molecular genetic events that participate in the genesis and progression of hemangiopericytoma. In this study, we describe two cases of hemangiopericytoma accompanied by severe hypoglycemia. Tumor cells from patient 1 exhibited insulin-growth factor I (IGF I) and insulin-like growth factor I receptor (IGF IR) mRNA(More)
OBJECTIVE To evaluate the safety of elective laparoscopic cholecystectomy (LC) as a supervised teaching procedure. DESIGN Prospectively documented series, retrospective analysis. SETTING University teaching hospital, Austria. SUBJECTS 581 consecutive patients who underwent elective LC for symptomatic cholelithiasis between January 1993 and December(More)
The replacement of endothelium by endothelial progenitor cells (EPCs) for therapeutic use in order to ameliorate the vascular status of ischemic organs is now in the focus of vascular research. The aim of our studies was to investigate whether EPCs derived from peripheral blood mononuclear cells (PBMNCs-derived EPCs) or EPCs propagated from CD34+(More)
Effects of sensory-motor cortical lesions on the function of the blood-brain barrier in distant brain areas are poorly understood. Therefore a brain vascular perfusion method has been used to measure simultaneously the kinetics of entry of two inert polar molecules, D[14C]mannitol (MW 180) and [3H]polyethylene glycol (PEG; MW 4000), into the parietal(More)
