BACKGROUND: Single-embryo transfer is a well-accepted strategy to avoid multiple pregnancies in an assisted reproductive technology programme. The selection of the embryo with the highest implantation potential is a crucial step. Besides the morphological quality and embryo kinetics up to the blastocyst stage, pre-implantation genetic screening (PGS) of aneuploidy has been advocated as an adjuvant approach by which to select the right embryo for transfer. METHODS: Couple...
Currently, there are no data available regarding the effect of vorapaxar on clot generation kinetics or TIP-FCS when added to standard of care antiplatelet regimens. Potential reduction of TIP-FCS and clot generation kinetics by vorapaxar may assist in our understanding of the mechanism of action and in personalizing therapy in high risk patients to effectively reduce recurrent thrombotic event occurrences. The objective of this study is to determine onset-, maintenance-, and o...
The purpose of this study is to find out the safety and activity of an experimental anti-HIV treatment using autologous CD4-zeta gene-changed T cells and/or IL-2 (recombinant interleukin2). The treatments that the investigators are studying try to improve the immune system by changing some of your T cells so they can find and destroy HIV infected cells (HIV is usually able to hide from your T cells). In this study, the investigators are also trying to find out if giving you mo...
Numerous studies about the potential role of NK alloreactiv during a n hematopoietic stem cells graft are based on genotypics analyses of the KIR receptors and on genotypic incompatibilities between KIR and HLA for couple donor/recipient. There is still a lot of issues non resolved: Are KIR really expressed and how occur their expression during time when hematopoïetic reconstitution? Is it depending on HLA of the recipient?If KIR are expressed, what are the mechanisms of allor...
RATIONALE: Measuring blood levels of tumor cells in patients with breast cancer may help doctors predict how patients will respond to treatment. PURPOSE: This laboratory study is looking at blood levels of tumor cells in predicting response in patients receiving first-line chemotherapy for stage IV breast cancer.
Microparticles have recently emerged as a thrombotic risk marker with a potential role in determining which patients are at greatest risk for developing thrombosis. Available data show an increase in the level of microparticles in cancer patients who are undergoing chemotherapy for solid tumors with a possible link to their thrombogenic state. Our study focuses on the kinetics of microparticles under chemotherapy in patients with pancreatic or gastric cancer by serial measurem...
The main target populations for the tetravalent live attenuated dengue virus vaccine are indigenous populations, especially infants less than 2 years old, residing in areas of the world endemic for dengue and at risk of developing dengue hemorrhagic fever (DHF). The presence of maternal dengue antibody during the first year of life makes it unlikely that a vaccine given during that time will have long-term efficacy, as the vaccine virus would likely be neutralized prior to nece...
The goal of this study is to characterize tau kinetics and tau aggregation in the human CNS and to test the hypothesis that tau kinetics are altered (i.e. increased production, decreased clearance, and increased aggregation rate) in tauopathies.
As yet we do not understand if there are biomarkers of immune protection after the Flumist or Live Attenuated Flu Vaccine (LAIV). Here we test the hypothesis that the T-bet expressing fraction of flu-specific B cells after live attenuated influenza vaccination also serves as anearly biomarker of long-lived antibody responses after vaccination. In this study we will be providing the LAIV to up to 10 healthy subjects and assaying their immune response and then providing the intra...
Primary objective of the study is to evaluate the correlation between level of HER2-neu gene amplification evalued by dual-color Fluorescent in-situ hybridization (FISH) test and time to progression (TTP) in patients with HER2-positive advanced breast cancer treated with trastuzumab-containing regimens.
Women were given a vitamin A tracer, and blood was sampled to determine individual and group vitamin A kinetics. Data were subsequently modeled using compartmental analysis to determine effects of study length on model outcomes.
This study will determine whether it is safe and effective to administer Japanese encephalitis (JE) live attenuated SA 14-14-2 vaccine at the same time as measles vaccine. If it is found to be safe, it will pave the way for use in routine vaccination programs. The hypothesis is that children who receive JE live attenuated SA 14-14-2 vaccine and measles vaccine at the same time are protected against these diseases at the same level as those who receive the vaccines at different ...

RATIONALE: Drugs used in chemotherapy, such as docetaxel, cisplatin, fluorouracil, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Lapatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving combination chemotherapy together with radiation therapy, with or without lapatinib, befor...
The primary purpose of the study is to evaluate the association of a latent infection of lymphoid cells during the first manifestation of steroid sensitive nephrite syndrome. The thirty nine units of general pediatrics and pediatric nephrite covering the parisian area will participate to the study. We speculate that hybridization of the genome, or a part of the genome, of a virus in lymphoid cells is responsible specific changes of genes expression, leading to the development o...
A combination of diabetes and neuropathy can cause an altered gait, increased tissue stiffness, limited joint mobility, muscle weakness, foot deformities, thus leading to excessive plantar pressure. The presence of an increased plantar pressure and the loss of sensation is a serious risk factor in the risk of development of diabetic foot ulcers (DFU). Therefore, appropriate shoes and insoles are recommended to redistribute high peak pressure (PP) and reduce pressure time integr...
