1. Three-dimensional ultrasound studies of normal and abnormal ovaries
Abstract : The aims of this work were: 1) to estimate the number of follicles, ovarian volume and power Doppler vascular indices and their changes with age using three-dimensional (3D) transvaginal grey-scale and power Doppler ultrasound in asymptomatic women of fertile age either with natural menstrual cycles or using combined oral contraceptives, and 2) to determine whether tumour vascularity, assessed by 3D power Doppler ultrasound, can help discriminate between benign and malignant ovarian tumours. A group of 303 gynaecologically asymptomatic women, aged 20–39 years with normal menstrual cycles (NMC) and another group of 213 women aged 20–39 years using combined oral contraceptives (COC) were examined using two-dimensional (2D) and 3D transvaginal ultrasound once between cycle day 4 and 8.

2. Human cytokeratins : their use as targets in cancer management
Abstract : Cytokeratins, biochemically related to intermediate filaments (IF), form an intracellular network of filaments which contributes to the mechanical stabilizing of the cell. 19 individual polypeptides, divided into two groups, constitute the cytokeratin family. READ MORE

3. Elucidating the role of 17β hydroxysteroid dehydrogenase type 14 in normal physiology and in breast cancer
Abstract : Oestrogens play key roles in the development of the majority of breast tumours, a fact that has been exploited successfully in treating breast cancer with tamoxifen, which is a selective oestrogen receptor modulator. In post-menopausal women, oestrogens are synthesised in peripheral hormone-target tissues from adrenally derived precursors. READ MORE

4. Analysis of HLA-A2 frequency as prognostic and/or risk factors in ovarian cancer patients
Abstract : Major histocompatibility complex antigens are mandatory for the immune response, and genetic imbalance may be linked to tumour escape. The HLA-A2 allele in Scandinavia has a high prevalence; it decreases with latitude and also with ovarian cancer mortality in Europe. READ MORE
