The aim of this prospective study was to investigate the ability of transvaginal power Doppler ultrasonography to assess the relationship between follicular vascularity and outcome in women undergoing in-vitro fertilization. Each of 38 subjects underwent a single transvaginal power Doppler ultrasound scan on the day of oocyte collection, where the(More)
Objective menstrual blood loss measurements (in ml) were compared with the score obtained from a pictorial blood loss assessment chart (PBAC) which took into account the degree to which each item of sanitary protection was soiled with blood as well as the total number of pads or tampons used. Twenty eight women used the chart during 55 menstrual cycles and(More)
OBJECTIVE To determine the permeability of unfertilized human oocytes to water and the cryoprotectant propane-1,2-diol over a range of temperatures and to use these data to predict osmotic responses under given conditions. DESIGN Laboratory-based study. SETTING Teaching hospital. PATIENT(S) Infertility patients donating unfertilized oocytes in excess(More)
BACKGROUND Vascular endothelial growth factor (VEGF) is being investigated for therapeutic angiogenesis in ischemic myocardium. Primarily, transient delivery systems have been tested. The goal of this study was to investigate the effects of continuous expression of VEGF in myocardium by use of myoblast-mediated delivery. METHODS AND RESULTS Primary murine(More)
Eighty-eight clomiphene citrate-resistant infertile patients with oligomenorrhoea or amenorrhoea attributable to polycystic ovarian disease were divided at random into three groups. Twenty-nine patients were treated with ovarian electrocautery, 30 with human menopausal gonadotrophins (hMG) and 29 with pure follicle stimulating hormone (FSH). Successful(More)
The aim of this prospective study of the use of transvaginal power Doppler ultrasound was to assess the subjectivity of the grading system and to elucidate, on a much larger series (200) of treatment cycles, the findings of previous authors. Vascular perfusion was studied using a grading system based on the percentage of follicular circumference (grade 1 <(More)
Estrogen withdrawal in women leads initially to rapid bone loss caused by increased numbers or activity of osteoclasts. We previously have noted apoptosis of lacunar osteocytes associated with conditions of high bone turnover. Therefore, in this study, we investigated whether the increased bone loss associated with GnRH analogue (GnRH-a)-induced estrogen(More)
OBJECTIVE To determine the long-term recurrence rate of endometriosis after treatment with gonadotropin-releasing hormone analogues (GnRH-a). DESIGN A historical prospective study. SETTING Royal Free Hospital, London, a tertiary referral center for the treatment of endometriosis. PATIENTS One hundred thirty patients with endometriosis had treatment(More)
Voltage gated potassium channels have been extensively studied in relation to cancer. In this review, we will focus on the role of two potassium channels, Ether à-go-go (Eag), Human ether à-go-go related gene (HERG), in cancer and their potential therapeutic utility in the treatment of cancer. Eag and HERG are expressed in cancers of various organs and have(More)
