To investigate the imaging performance characteristics of AIDS patients with pulmonary fungal infection. Methods: Fifty-one cases of AIDS with pulmonary fungal infections patients and 56 cases of non-...
CONTEXT: Although pregnancy ambivalence is consistently associated with poorer contraceptive use, little is known about the sexual, social and emotional dynamics at work in pregnancy ambivalence. ...
CONTEXT: Women choose medical over surgical abortion because it is more natural, more private and less painful. Whether their perceptions change during the medical abortion process has not been explor...
The automated analysis of sperm motion endpoints is potentially useful in identifying male reproductive toxicants and ultimately in predicting fertility in humans. The present study was designed to ...
Intra- and inter-technician variability in assessing sperm motility by the methods recently advocated by the World Health Organization (WHO) were studied. The intra- and inter-technician variability...
The ability of human spermatozoa to exhibit sperm-oocyte fusion in response to the ionophore, A23187, was examined in relation to the capacity of these cells to generate reactive oxygen species. I...
In vitro fertilization (IVF) and GIFT have been proposed as therapeutic approaches in infertile couples where a significant male factor is present. To date, few published data are available relati...
Multivariate discriminant analysis was used to evaluate the usefulness of computer image analysis of sperm movement characteristics and differential patterns of sperm tail swelling after hypoosmot...
Two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) was used to analyze the polypeptide composition of rat cauda epididymal fluid, blood serum and membrane-enriched fractions of caput, corp...
Videomicrographic computer-automated semen analysis systems allow quantitative description of sperm motility, velocity, progression, and head movement amplitude and frequency with unprecedented ease...
Quantitative methods for the determination of the concentration, percent motility and swimming speed of human and animal spermatozoa can assist in the objective analysis of sperm and semen quality. ...
A videomicrographic system was developed for measurement of morphometric parameters of human spermatozoa. Contours of the images of spermatozoa on a video monitor are digitized by manually tracing t...
Rat seminiferous tubule segments have been cultured in chemically defined medium (F12/DMEM 1:1) without added hormones or growth factors. The segments (1-2 mm) were isolated from defined stages of t...
The stages of the rat seminiferous epithelial cycle have been isolated for flow cytometric analysis of DNA and for culture, using transillumination-assisted microdissection. Precise stages have been...
8-Azido cAMP photoaffinity labeling of cAMP-dependent protein kinase regulatory subunits (R1 = 49 K;R2 = 55K) was done on spermatozoa from species lacking, and species containing an epididymis. Sper...
