Ten-Eleven Translocation (Tet) family of dioxygenases dynamically regulates DNA methylation and has been implicated in cell lineage differentiation and oncogenesis. Yet their functions and mechanisms of action in gene regulation and embryonic development are largely unknown. Here, we report that Xenopus Tet3 plays an essential role in early eye and neural(More)
1. Conflicting reports in the literature over heterogeneity (West et al., 1990) or homogeneity (Arrange et al., 1990) of histamine H3-receptor binding sites may be attributed to the use of different incubation conditions. In the present study we have investigated the extent to which the binding of H3-receptor ligands to rat cerebral cortical membranes can(More)
Some of the most significant therapeutic leads and agents used for the treatment of cancer target microtubule dynamics. Paclitaxel is an exceptional example that is currently used for treating a wide range of tumors. New, non-taxane microtubule stabilizers, including several epothilones, are advancing through clinical trials. Laulimalide is a potent(More)
BACKGROUND Physical and sexual violence heighten STI/HIV risk for women in sex work. Against this backdrop, we describe the nature of abuse against women in sex work, and its STI/HIV implications, across perpetrators. METHODS Adult women involved in sex work (n = 35) in Baltimore, MD participated in an in-depth interview and brief survey. RESULTS(More)
Stenotrophomonas maltophilia has emerged as a significant pathogen in compromised patients, causing infections which are difficult to treat. Clinical isolates from patients in the Tucson area were tested against single and combination antibiotics using three testing methods. Ticarcillin/clavulanate, trimethoprim/sulfamethoxazole and trovafloxacin provided(More)
BACKGROUND The addition of azithromycin to standard regimens for antibiotic prophylaxis before cesarean delivery may further reduce the rate of postoperative infection. We evaluated the benefits and safety of azithromycin-based extended-spectrum prophylaxis in women undergoing nonelective cesarean section. METHODS In this trial conducted at 14 centers in(More)
Further analysis of three sterol-nonrequiring Mollicutes (strains PS-1, TAC, and YJS) isolated from gut fluids of insects confirms their similarity to Acholeplasma. They are serologically distinct from acholeplasmas of vertebrates and several other sterol nonrequiring Mollicutes isolated from plant surfaces. The PS-1 strain had a DNA G + C content of 31 mol(More)
Concern regarding the association between cesarean delivery and long-term maternal morbidity is growing as the rate of cesarean delivery continues to increase. Observational evidence suggests that the risk of morbidity increases with increasing number of cesarean deliveries. The dominant maternal risk in subsequent pregnancies is placenta accreta spectrum(More)
