The effects on indices of gingivitis/periodontitis will differ between study arms in which the titanium dioxide semiconductor toothbrush is used, compared to an otherwise identical toothbrush with an inert resin core in place of the titanium dioxide semiconductor.
The semiconductor (cadmium-zinc-telluride, CZT) cameras significantly increase detection sensitivity in Single Photon Emission Computer Tomoscintigraphy (SPECT)(1) . The clinical routine applications of these cameras are today mainly limited to myocardial tomoscintigraphy with CZT dedicated cameras. Several studies whose one was done in CHRU of Nancy, made it possible to demonstrate a good diagnosis agreement between conventional cameras and semiconductor cameras in this indica...

This pilot clinical trial studies the use of integrin alpha-v-beta [18F]-R01-MG-F2 positron emission tomography (PET)/computed tomography (CT) in measuring response in patients with pancreatic cancer and healthy volunteers. Integrins, such as integrin alpha-v-beta [18F]-R01-MG-F2, are a family of membrane receptors that are overexpressed and attaches to various proteins which sense and respond to contact events that occur at the cell surface and may improve early detection of p...
This clinical trial studies use of [F-18] 16 alpha-fluoroestradiol ([F-18] FES) positron emission tomography (PET) in measuring tumor hormone receptor expression in patients undergoing endocrine-targeted therapy for newly diagnosed breast cancer or breast cancer that has come back or spread to other places in the body. Comparing results of diagnostic procedures done before, during, and after hormone therapy may help measure a patient's response to treatment.
Endoscopic tattooing to facilitate colorectal lesions' identification during laparoscopic surgery is a reliable and widely used technique. India Ink is the standard option for colonic tattoing. Different studies have been reported significant complications, of which the most common is peritonitis, due to ethylene glycol, phenols and animal-derived gelatine contained in the ink. This local inflammatory reaction is the principal reason of the formation of the adhesions detected ...
The purpose of this observational study is to describe the environmental aerosolization patterns burden of RSV in the air and on surfaces in surrounding adult patients in a real-life setting. Specific objectives are to determine the particle size distribution and the quantity of airborne pathogens dispersed by symptomatic participants, to establish a spatial model of airborne emission and subsequent surface burden of RSV emission and dispersal in clinical settings (emergency de...
This study will evaluate the effect of allograft bone particle size on the bone quantity and quality following socket grafting and lateral ridge augmentation in preparation for endosseous implant placement. Pre (baseline)- and post-grafting (3 months for sockets and 6 months for edentulous ridges) clinical as well as 2- and 3-dimensional radiographic measurements will be used to evaluate the differences between sites grafted with small vs. large particle sized bone allografts....
The purpose of this explorative trial is to collect preliminary data on efficacy and safety of thymosin alpha 1 given at different doses as an adjuvant to egg-derived H1N1sw monovalent influenza vaccine in hemodialysis patients. The final aim is that of gathering information needed for planning a following confirmatory study on the efficacy and safety of Thymosin alpha 1 in the same indication.
The purpose of the study is to test safety and efficacy of different doses of thymosin alpha 1 (1.6 mg, 3.2 mg, and 6.4 mg) in combination with dacarbazine and with or without Interferon alpha in treating patients affected by stage IV melanoma. Primary end-point is Tumor Response evaluated according to Response Evaluation Criteria In Solid Tumors (RECIST). Secondary end-points are Overall Survival and Progression Free Survival. Ninety-five patients are allocated to each...
Cross-over trial of the effect of a salt particle inhaler on pulmonary muco-ciliary cleansing in COPD patients as measured by lung scintigraphy.
Study to Test the Safety and How Radium-223 Dichloride an Alpha Particle-emitting Radioactive Agent Works in Combination With Pembrolizumab an Immune Checkpoint Inhibitor in Patients With Stage IV Non-small Cell Lung Cancer With Bone Metastases
The purpose of the study is to determine the safety and test the efficacy of the combination of radium-223 dichloride and pembrolizumab in patients with stage IV non-small cell lung cancer (NSCLC) with bone metastases who either have not received any systemic therapy for their advanced disease or have progressed on prior immunologic checkpoint blockade with antibodies against the programmed cell death protein-(ligand) 1 (PD-1/PD-L1). In this study researchers want to measure tu...
An investigator initiated pilot trial: two arm, double blind, placebo controlled, randomized, parallel group of approximately 750 patients with chronic kidney disease, and who have evidence of overt proteinuria, will be treated with micro-particle curcumin versus placebo over 24 weeks from start of the investigational medication date (approximately 6 months) to test whether curcumin can slow chronic kidney disease progression in patients. Three 30 mg capsules of micro-particle ...
This pilot trial studies how well telotristat etiprate works in treating participants with well differentiated neuroendocrine neoplasm that has spread to other places in the body and monitored by carbon C 11 alpha-methyltryptophan (AMT)-emission tomography (PET). Telotristat etiprate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Studying the changes within the tumor cells via AMT-PET may help doctors better understand how tumors resp...
The primary goal of the study is to see if the PET/CT will be able to determine the precise location of the Y-90 particles within the liver and within the tumors. We hope to use this information in order to see if these particles distribute evenly throughout large tumors or if the particles go into the tumor which is located in the portal vein. The secondary goals are threefold. First correlate the distribution of Y90 particles (as demonstrated by PET/CT) with the degree of de...
Biologics are routinely used for the treatment of rheumatoid arthritis (RA). Adalimumab is a human monoclonal antibody that inhibit the Tumor Necrosis Factor alpha (TNF-alpha). Identification of RA patients who respond to biologics is a challenging goal to avoid unnecessarily, costly and potentially harmful treatment. The aim of the study is to address if 18 F FDG is a valuable biomarker for the assessment of the clinical response in RA with TNF-alpha blocking agent. Eight pa...
The primary objective of the study is to show that ventilation heterogeneity identified by hyperpolarized helium-3 lung MRI is prevalent children with poorly controlled asthma despite guidelines-based treatment with ICS. The secondary objective is to demonstrate whether or not eight weeks of treatment with extra-fine particle ICS (HFA-BDP) improves ventilation heterogeneity compared to treatment with a coarse particle ICS (fluticasone HFA or dry powder).
The purpose of study is to examine whether raised blood glucose enhances lipid particle production independent of effects on gastric emptying and pancreatic/ gastrointestinal hormone production.
