Human decidual tissue appears to play an important role not only in nurturing the implanted embryos, but also in preventing its rejection by the maternal immune system. Insight into the maternal immunologic modulations during implantation is our main research interests. Our previous studies have shown that most lymphocytes in deciduae are natural killer cells. However, their phenotype is CD16-CD56+CD3-, which is different from that of peripheral natural killer cells. More impor...
Myriads of elements affect human embryo culture in vitro. These include, but not limited to, air quality, culture media, culture temperature, incubator humidity, pH, and O2 levels. O2 tension has been thoroughly investigated and, to date, 5% O2 level is superior to 20%. Reports showed that lowering the O2 from Day 3 of embryo culture seems to be physiological.
One of the vital factors in achieving pregnancies in assisted reproductive technologies (ART) is maximizing embryo quality, which is significantly influenced by embryo culture conditions. A microwell culture system that facilitates group culture, improves embryonic development. The investigators use a new special culture dish to examine the effect of group culture on embryonic development in vitro. Zygotes derived from sibling oocytes were completely denuded from cumulus cells ...
Patients with negative blood cultures represent 85-90 % from all patients with a blood culture taken during hospital admissions. This population usually includes an heterogeneous group of patients that are admitted because of an infectious diseases or febrile syndrome in which performing a blood culture is required. There is scarce evidence about the clinical characteristics and the antibiotic treatment given to these patients. This project will be developped in two phases with...
Due to a number of factors, including power differentials and adverse events, residents are susceptible to mistreatment (i.e., discrimination, harassment, and abuse) and toxic outcomes (i.e., burnout, attrition, and suicide). Our subsequent work following the FIRST Trial identified considerable variation in program-level rates of resident-reported burnout, severe stress, gender discrimination, racial discrimination, sexual harassment, and verbal abuse. To investigate these issu...
Embryo culture is a cornerstone of in vitro fertilization treatments. Usually, embryos are cultured in microdrops of culture media in incubators with controlled temperature, humidity and atmosphere. However, these culture systems are static, while in vivo the initial growth of the embryo takes place in the uterine tube and they are submitted to a dynamic environment. The aim of this study is to compare the embryo development on days 2 and 3 of culture morphological features of ...
Culture media to support development of zygotes to the blastocyst stage is based on two basic philosophies: a single step medium "let-the-embryo-choose" or a sequential medium "back-to-nature". For single step media, there are two types of protocol can be used for the culture of human preimplantation embryos: 1. Interrupted single medium culture, in which the medium is renewed on the Day 3 of embryo culture 2. Uninterrupted single embryo culture, in whic...
The objective of this study is to demonstrate that frequent atrio-ventricular (AV/PV) and inter-ventricular (V-V) delay optimization using QuickOpt in patients with CRT-D device results in improved clinical response over standard of care (i.e. empiric programming or one-time optimization using any non-IEGM optimization methods).
Amikacin dose optimization is challenging in critically ill patients. The use of BestDose software algorithm-based drug optimization could help to achieve the recommended target concentrations (60-80 mg/L) after administration of the second dose of amikacin, associated with improved outcome. The study investigators hypothesize that 80% of patients undergoing drug dosing optimization using the BestDose software in the interventional group will reach the predefined PK/PD targets.
This study is to assess whether addition of 2 ng/ml GM-CSF into a specific culture medium will increase the chance of a pregnancy after in vitro fertilisation.
This Clinical Study has been designed to assess and compare the impact of in vitro or in vivo culture conditions on the euploidy of sibling blastocysts.
To determine the safety of 2 intravenous injections of autologous or allogeneic LMP-specific cytotoxic T-lymphocytes (CTL) in patients with EBV-associated Hodgkin's Disease or lymphoma/lymphoproliferation/severe chronic EBV. To determine the survival and the immune function of LMP-specific cytotoxic T-lymphocyte lines. To assess the anti-viral and anti-tumor effects of LMP-specific CTLs. To obtain preliminary information on the safety and response to an extended dosage...
30% of heart failure patients that receive a device for cardiac resynchronization therapy fail to show clinical improvement. The reason for lack of response is still unclear but factors such as scar tissue in the heart musculature, inadequate lead placement, device-settings and the degree of dyssynchrony before implant seems to be important. In this study, these factors are further investigated.
The purpose of this study is to determine the largest and safest dose of Adenovirus (AdV)-specific cytotoxic T cells to be administered to individuals following a stem cell transplant, to evaluate the side effects of this treatment, and to examine whether this therapy might help prevent and treat AdV infection in these individuals.
Cytokine-induced killer (CIK) cells exhibit high proliferation rate and cytotoxic activity in vitro. The major effector cells are the CD3+CD56+ subset. The cytolytic activity of CIK cells being independent of MHC restriction implies feasibility in using CIK cells allogeneic to the tumors. Experiments to block the MHC class-I and -II pathways on tumors-RNA transfected DCs showed that only MHC class-I blocking led to a significant reduction of heterogeneous CIK cells cytotoxic...
Despite advancements in implant technology and various techniques of optimization, there is still around 30% non-responder rate to cardiac resynchronization therapy (CRT). This study will assess the potential benefit of a body surface mapping technology to optimize CRT devices in the chronic sub-optimal responder setting.
Acute cholangitis with obstructive jaundice is a condition which needs biliary drainage and appropriate antibiotics. Bile culture is an optional laboratory test according to 2013 Tokyo guideline, but the clinical significance is yet unproven. And its results might indicate less information of the true pathogen regarding normal flora. Previous study conducted at our institute found drug-resistant pathogens identified in bile culture had no impact on the outcome. So the investiga...
The purpose of this study is to collect development and outcome data on human embryos which are cultured in a 2nd generation continuous single culture medium (CSCM2) with the objective to demonstrate its performance efficacy in comparison to existing commercially available single culture or continuous embryo culture media.
The aim of this non-interventional study is to compare the blastulation rate per fertilized oocyte in two different single step culture media commercially available (GEMS and Irvine culture media).
