Proper positioning of mitotic spindles ensures equal allocation of chromosomes to daughter cells. This often involves interactions between spindle and astral microtubules and cortical actin. In yeast and Caenorhabditis elegans, some of the protein machinery that connects spindles and cortex has been identified but, in most animal cells, this process remains(More)

Various adhesives have been used to increase the adherence of tissue sections to glass slides and to prevent separation during staining. Traditionally glyc-erin albumin' and gelatin2 solutions have been widely used in routine histology. More recently poly-L-lysine has been used to improve section adhesion, particularly in immunocytochemistry.3 This method(More)
Several studies have examined the role of tests for human papillomavirus (HPV) in screening for cervical cancer but as yet the relevance is unclear. We looked at HPV testing for types 16, 18, 31, and 33 on material taken at the time of a cervical smear in 2009 eligible women having routine screening. Women with any degree of dyskaryosis or high levels of(More)
Langerhans' cells in cervical epithelium in colposcopic biopsy specimens were identified by immunocytochemical staining for S100 protein and T6 (CD1) antigen, and their density was quantified. Possible cofactors for the development of cervical neoplasia were examined for any effect on the cell counts per unit area. Current cigarette smoking was associated(More)
AIM To examine the value of immunohistochemistry in defining a keratin profile to aid cervical histopathological diagnosis. METHODS Immunohistochemical localisation of keratins 17, 10, and 19 was studied in 268 cervical biopsies from 216 women including normal epithelia (with and without human papilloma virus), low and high grade cervical intraepithelial(More)
We investigated the mechanism by which meiotic spindles become bipolar and the correlation between bipolarity and poleward flux, using Xenopus egg extracts. By speckle microscopy and computational alignment, we find that monopolar sperm asters do not show evidence for flux, partially contradicting previous work. We account for the discrepancy by describing(More)
