Rationale: Pancreatic adenocarcinoma is a malignancy with a poor prognosis. Resection is the only curative option and still 5-year survival rate is less than 10 percent. However, most patients present with advanced disease and are provided with palliative care. The nature of the tumour and the intense stromal reaction around the tumour cells leave pancreatic adenocarcinoma relatively insensitive to chemotherapeutics. Current models, such as cell lines or patient derived xenogra...
The study has two objectives: 1. To obtain endoscopic and colonoscopic biopsies to harvest and culture intestinal crypts from human tissue to produce organoids. These organoids will be used to study the biology of innervated sensory epithelial cells. 2. to collect subject data relating to clinical management and demographic characteristics of patients undergoing upper endoscopy or colonoscopy to learn the mechanisms behind visceral hypersensitivi...
Patients with locally advanced rectal cancer will receive biopsy before the standard treatment of neoadjuvant chemoradiation. The investigators are going to establish organoids model from the pre-treatment biopsies and expose organoids to irradiation and the same chemotherapy drugs. The sensitivity of irradiation and chemotherapy drugs will be tested in the organoids model. Here, the investigators will launch the observational clinical trial to validate whether the organoids co...
Lack of depth perception and spatial orientation are drawbacks of laparoscopic surgery. The advent of the three-dimensional (3D) camera system enables surgeons to regain binocular vision. The aim of this study was to gain subjective and objective data to determine whether 3D systems are superior to two-dimensional (2D) systems.
Traditionally, laparoscopy has been based on 2-dimensional (2D) imaging, which has represented a considerable challenge for those approaching this technique. Thus, 3-dimensional (3D) visualization technology for laparoscopy has been proposed, since the early 1990s, as a way to facilitate laparoscopic performance. However, early 3D laparoscopic technology was limited in terms of image quality, so that its use had not been implemented. More recently, industry has developed novel ...
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 ...
The centre for Medically-Assisted Procreation (MAP) of Dijon CHU has two high-technology embryo culture systems, with incubation characteristics that are potentially superior to those provided by classical culture systems. Indeed, these two systems, available in only two MAP centres in France, make it possible to maintain a stable temperature and gaseous environment during the in-vitro development of the embryos. It is necessary to observe the development of the embryos to det...
Upon collection, human oocytes are fertilized and culture up to the blastocyst stage, followed by transfer and / or cryopreservation. Culture media systems have been developed that support each step of this process. Although these culture media systems try to mimic the natural environment, several components of the in-vivo situation are not present in today´s media. One such component is anti-oxidants that may protect embryos against damage by reactive oxygen species. T...
RATIONALE: Using computer systems that create a 3-dimensional picture of the tumor to plan treatment may enable doctors to provide more effective radiation therapy that will cause less damage to normal tissue. PURPOSE: This phase I trial is studying the side effects and best dose of high-dose 3-dimensional conformal radiation therapy in treating patients with inoperable stage I, stage II, or stage IIIA non-small cell lung cancer.
A monocentric pilot studying intestinal organoids from endoscopic biopsies of IBD (Crohn and ulcerative colitis), FAP patients and healthy controls. Investigate the morphological characteristics of organoids, the expression of genes and proteins of the Wnt/APC/beta-catenin pathway within both ISC.
We are going to establish "organoid" models from pancreatic cancer biopsies achieved via EUS-FNA. Then the sensitivity of the selected FDA-approved anti-cancer drugs will be tested in these organoids.
Compare operative times and complications of sacral colpopexy and paravaginal repair between two-dimensional and three-dimensional laparoscopic systems.
Rationale: Computer systems that allow doctors to create a 3 dimensional (3-D) picture of the tumor may help in planning radiation therapy and may result in more tumor cells being killed. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs, such as cisplatin, may make tumor cells more sensitive to radiation therapy.
This clinical trial studies if kilo-voltage cone beam computed tomography (KV-CBCT) and ultrasound imaging works in guiding radiation therapy in patients with prostate, liver, or pancreatic cancer. Computer systems, such as KV-CBCT and ultrasound imaging, allow doctors to create a 3-dimensional picture of the tumor may help in planning radiation therapy and may result in more tumor cells being killed.
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.
Introduction: Three-dimensional key-hole surgery ('laparoscopic') systems are proven to reduce the time required to complete tasks in laboratory settings. This benefit derives from the addition of binocular depth perception cues when compared to two-dimensional (2D) systems. This year a '4K' laparoscopic system has become commercially available, so-named as it provides a high resolution 2D image with four times the number of pixels of 2D full high definition. The improved visua...
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Computer systems that allow doctors to create a 3-dimensional picture of the tumor to plan treatment may result in more effective radiation therapy. It is not yet known which chemotherapy and/or radiation therapy regimen is more effective in treating non-small cell lung cancer. PURPOSE: Ra...
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Computer systems that allow doctors to create a 3-dimensional picture of the tumor in order to plan treatment may result in more effective radiation therapy. PURPOSE: This phase II trial is studying how well radiation therapy that has been planned with a computer works in treating patients with prostate cancer.
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...
Measuring appearance of implant-based breast reconstruction after mastectomy for breast cancer - an online approach to research. Using 3-dimensional surface images we intend to create a tool to measure appearance after surgery in order to improve standards of care for women. We want to minimise the number of visits and amount of time involved in research participation so this pilot study will develop new online tools for information giving and gathering, and for consent so that...
Ultrasound imaging (US), a radiation-free imaging modality, is currently used in diagnosis of developmental dysplasia of the hip (DDH) in infants. The current protocol involves manually identifying specific measures that are prone to error, and may give rise to false positives. We aim to use 2-dimensional (2D) and 3-dimensional (3D) ultrasound imaging to create an automatic measurement procedure that we hope will reduce the errors in measurement and increase reliability.
The aim of this project is to create ten smart devices that involve combining an interactive art environment with IC technology, arts and health administration. We invited the elderly residents of Chang Gung Health and Culture Village to participate in the application of these devices, and they were also requested to complete a technology acceptance model (TAM) questionnaire for these smart devices.
