Endometriosis is one of the most common causes of infertility and chronic pelvic pain and affects 1 in 10 women in the reproductive-age group. Although existence of this disease has been known for over 100 years, our current knowledge of its pathogenesis, the pathophysiology of related infertility, and its spontaneous evolution is limited. Several reasons(More)
OBJECTIVE To evaluate steroid receptor and aromatase gene expression in endometriotic lesions, and determine the effects of endometriosis on uterine receptivity in a baboon model for endometriosis. DESIGN Prospective study to determine the expression of steroid receptors, and aromatase in ectopic endometriotic lesions and endometrial genes in the eutopic(More)
OBJECTIVE To determine the impact of physiologic changes of pregnancy on pharmacokinetics of chemotherapeutic agents. DESIGN A preclinical and a clinical case-control trial. SETTING Institute of Primate Research Nairobi and collaborating hospitals in Belgium, the Netherlands and Czech Republic. POPULATION Pregnant and nonpregnant women and baboons(More)
OBJECTIVE The paucity of data on the fetal effects of prenatal exposure to chemotherapy prompted us to study transplacental transport of chemotherapeutic agents. METHODS Fluorouracil-epirubicin-cyclophosphamide (FEC) and doxorubicin-bleomycin-vinblastine-dacarbazine (ABVD) were administered to pregnant baboons. At predefined time points over the first 25(More)
Endometriosis is associated with chronic inflammation, including an increased macrophage activity with increased secretion of cytokines, such as tumor necrosis factor (TNF) or TNF superfamily member 2, previously known as TNFalpha. In the present study, we tested the hypothesis that recombinant human TNFRSF1A (r-hTBP1) can inhibit the development of(More)
A study was undertaken to categorise some gastro-intestinal (GIT) parasites commonly observed in Kenyan non-human primates (NHPs) on the basis of their health implications for humans. Six species of locally available non-human primates, namely olive baboons (Papio cyanocephalus anubis), Vervet monkey (Cercopithecus aethiops), Sykes monkey (Cercopithecus(More)
Endometriosis, defined as the ectopic presence of endometrial-like cells, is associated with infertility and pelvic pain in women. Whereas pathogenesis and spontaneous evolution of endometriosis are still poorly understood, recurrences after surgical therapy or after medical treatment are common. Spontaneous endometriosis occurs only in women and in(More)
A total of 114 nonhuman primates comprising 51 vervet monkeys (Cercopithecus aethiops) and 63 olive baboons (Papio anubis) were examined for Cryptosporidium oocysts using the modified Kinyoun's acid-fast staining technique. About 51.7% (59/114) of all the specimens examined, representing 78.4% (40/51) of the vervet monkeys and 30.1% (19/63) of the olive(More)
BACKGROUND Inflammatory cytokines, including interleukin (IL)-1, IL-6, IL-8 and tumour necrosis factor-alpha (TNF-alpha), are important in the pathogenesis of endometriosis. We assessed the efficacy of anti-TNF monoclonal antibody (mAb, c5N), known to prevent induced endometriosis in baboons, in reducing established endometriosis in baboons. METHODS This(More)
BACKGROUND The paucity of data on fetal effects of prenatal exposure to chemotherapy prompted us to study the transplacental transport of commonly used anticancer agents in a pregnant baboon model. METHODS Single or combination chemotherapy with paclitaxel, docetaxel, carboplatin, and trastuzumab was administered to 9 baboons at a mean (SD) gestational(More)
