Filter by:The pharmacokinetics, safety, and tolerability of meloxicam eye drops in Chinese healthy volunteers were evaluated to provide a basis for the formulation of a phase II clinical trial dosing regimen for this product. Including pre-tests and formal trials, formal trials include single-dose pharmacokinetics tests and multiple-dose tolerance tests (4 times a day for 3 consecutive days).
The overall objective of this study is to compare the overall pattern of [18F]APN-1607 uptake in subjects with MDAD, subjects with AD dementia, and healthy subjects.
There is evidence that the bacteria that naturally reside in the gut can influence how well we respond to medications. Therefore this study will look at how rosuvastatin, a medication used to lower cholesterol levels, may change the bacteria in the gut. Investigators will also examine how the gut bacteria will affect the ability of rosuvastatin to lower cholesterol levels. There will be 4 study visits over the course of about 16 weeks.The expected duration of the study is 2 years. Investigators plan to enroll 100 healthy volunteers during that time.
Despite the known link between dietary patterns and disease, it has been observed that the specific response of each individual to dietary components highly varied, and this may limit the impact of the nutritional interventions to improve public health. These observations provided the basis to the development of the Nutritional Genomics at the beginning of the 90s, which main goal was to study the interaction between dietary factors and the genome that modulate phenotypic expression. From this idea, in the recent years, Precision Nutrition has been emerged as a therapeutic approach that takes into account all individual's characteristics to develop targeted nutritional advices. The main goal of Precision Nutrition is to maintain or improve health by using genetics, phenotypic, clinical, dietary and other information to provide more precise and more efficacious personalized healthy eating advice and to motivate appropriate dietary changes. However, all the genotype-dependent advice must be based on scientific evidence. Most of the available evidence in support of personalized nutrition has come from observational studies with risk factors as outcomes, and it was needed randomized controlled trials using clinical endpoints to ratify these results. The main objective of the Platform for Clinical Trials in Nutrition and Health (GENYAL) is to contribute to Precision Nutrition Research by the construction, for the first time, of a human gene and phenotype database to be used in: 1) The evaluation of the efficacy of different foods, functional foods and bioactive compounds capsules on general population and by genotypes and 2) The performance of nutritional genetics and nutrigenomics studies. For that purposes, GENYAL has a permanent recruitment of volunteers, which are phenotypically and genotypically characterized, and give consent to be contacted to perform clinical trials and nutritional intervention studies. Therefore, GENYAL may help to increase the existing knowledge for moving along to Nutritional Genomics research to its practical application in Precision Nutrition; contributing in the improvement in health and disease prevention through dietary recommendations based on the genome.
The research study is being conducted to test how a specialized type of Positron Emission Tomography (PET/CT) scan could potentially be useful in diagnosing or monitoring treatment in people with Parkinson's disease. If the subject decide to be in this study he/she will have a PET/CT scans using an imaging drug called 18F-NOS which will be used to measure inflammation in the brain.
Evidence has suggested that omega-3 fatty acids, namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have an important role in promoting cardiovascular health. However, the currently available scientific literature describing the postprandial effects and bioavailability of these fatty acids, particularly when they are incorporated into high protein food item, like canned tuna, is far from conclusive. The aim of this study is to evaluate the acute bioavailability of EPA + DHA enriched canned tuna and its acute effects on cardiovascular risk markers, in healthy human volunteers.
Probiotics are defined as "live micro-organisms that, when administered in adequate amounts, confer a health benefit to the host" (Hill et al, 2014). These microbes are generally applied in the gastrointestinal tract via fermented food products or capsules. In previous research, the investigators isolated bacterial strains with potential probiotic properties for the upper respiratory tract based on in vitro laboratory tests, in vivo mice experiments and genome sequencing. In this study, the investigators want to deliver the Proof-of-Concept that the most promising isolated strain, Lactobacillus casei AMBR2 (LAMBR2) and the well-documented probiotic strain Lactobacillus rhamnosus GG (LGG) also have interesting properties in humans, i.e. that these strains are able to -temporarily- persist in the upper respiratory tract of healthy volunteers and CRS patients after daily nasal application via a nasal spray for 2 weeks. In addition, the investigators aim to explore whether the application of these strains has an impact on the nasopharyngeal microbiome via 16S rRNA amplicon sequencing and dedicated qPCR analysis. Therefore, bacterial DNA from nasal swabs will be isolated via commercially available DNA extraction kits, followed by Illumina MiSeq sequencing in order to identify the bacterial species present in these samples. Furthermore, the concentration of the Lactobacillus and specific pathogens will be monitored via qPCR.
This is a seven-cohort, double-blinded, randomized, sham-controlled feasibility trial to determine whether organ-specific biological effects are achievable through selective ultrasound of the spleen utilizing low-energy insonification.
Bioavailability of dietary supplement formulations in healthy volunteers after a single oral dose.
This study is a Phase 1, randomized, double-blind, placebo-controlled, dose-escalation clinical trial to evaluate the safety and immunogenicity of NasoShield in healthy adults 18 to 49 years of age.
