Mycoplasmas are tiny polymorphic prokaryotic organisms (0.2-0.3 microm) that lack a cell wall and reside ubiquitously at the cell membrane or internalized into the cell. The organisms have been implicated in many diseases including functioning as cofactors catalyzing the HIV disease state. The oncogenic potential of mycoplasmas was only recently realized(More)
The ability to predict myometrial invasion by endometrial adenocarcinoma is useful for preoperative treatment purposes. The presence of stromal invasion is one possible method of predicting myometrial invasion, but criteria for the presence of stromal invasion have been lacking. Recently, criteria for its detection were proposed. We evaluated the validity(More)
OBJECTIVE To determine the prevalence of mycoplasmas in washed sperm and to compare the penetration of zona-free hamster oocytes by sperm with and without mycoplasmas. DESIGN Prospective comparative study. SETTING Clinical and academic research environment. PATIENT(S) Semen from 34 male patients. INTERVENTION(S) Specimens were divided, Percoll(More)
A case of malignant teratoma arising within a dysgenetic gonad in a 21-year-old phenotypic female with a 46 XY karyotype is presented. Admixtures of dysgerminoma, yolk sac tumor in close juxtaposition to embryoid bodies and elements of choriocarcinoma were also present. The contralateral gonad was an unidentifiable fibrovascular streak. Neither(More)
The present study demonstrated the presence of HPV gene sequences in Percoll-washed sperm cells using polymerase chain reaction primers targeting smaller gene regions. Up to 64% of the sperm specimens were shown to contain gene sequences indicative of the presence of HPV. Human papillomavirus type 16 was detected about twice as often as HPV type 18. The(More)
A 41-year-old woman presented with hirsutism, a pelvic mass, and Cushing's syndrome. Imaging studies revealed bilateral ovarian masses and a solid and cystic mass within the pancreas. Partial pancreatectomy, bilateral oophorectomy, and excision of several peritoneal tumor nodules were performed. Pathological examination revealed a neuroendocrine islet cell(More)
Clinically, it is important to detect mycoplasmas because these organisms have been implicated in gastric and ovarian cancer, pneumonia, postabortal fever, pelvic inflammatory disease, pyelonephritis, endometritis, urethritis, perinatal mortality, arthritis, spontaneous abortion, infertility and interference with sperm development and they act as cofactors(More)
The objective of the study was to determine if embryos at the blastocyst stage differentially took up exogenous human papillomavirus (HPV) DNA derived from the different HPV types and to determine whether the capture process was active or passive. In vivo fertilized mouse embryos were cultured to the blastocyst stage in vitro. The mouse blastocysts were(More)
A new method for reconstructing rat uterine horn was developed in which nonpenetrating, arcuate-legged clips are applied in interrupted fashion to everted seromuscular edges, forming an elastomeric flanged joint. This anastomosis has unusual physical and morphologic properties, with improved tissue healing and luminal restitution. Clipping is easier than(More)
