The Safety and Intake Rate of a Natural Compound Arctigenin in Healthy Men

Start date: January 15, 2019
Phase: Phase 1
Study type: Interventional

The purpose of this research study is to determine if consuming arctigenin, a natural compound from a Chinese herb called Arctium lappa (commonly called greater burdock), is safe, and to measure the intake level of arctigenin in blood. Arctigenin is being studied by researchers for potential health benefits such as helping to lower the risk of inflammation and cancer. A human study has been done measuring the uptake of arctigenin into blood after consumption of the herb extract containing arctigenin, and found no toxicity. Studies in mice demonstrated that consumption of arctigenin in pure form at a safe level is highly effective in inhibition of prostate cancer growth. Therefore, this study is designed to evaluate the safety and uptake rate of pure arctigenin in humans, which may be potentially used in the future for prostate cancer prevention.

NCT ID: NCT03703141 Completed - Healthy Clinical Trials

Serum Insulin Response After Acute and Chronic Sucralose Ingestion in Healthy Volunteers With Variable Body Mass Index

Start date: September 27, 2016
Phase: N/A
Study type: Interventional

The consumption of non-caloric sweeteners has increased worldwide; Current publications suggest its consumption associates to insulin resistance. The present study aims to demonstrate whether acute or chronic sucralose exposure affects insulin or carbohydrate metabolism or alters systemic inflammatory markers and microbiota in young, healthy adults. In this prospective, randomized, double-blind, placebo-controlled clinical trial, three groups will be included with 30 healthy volunteers each. Group A will receive sucralose 48 mg/ day, group B 96 mg/day and group C plain water as placebo. Subjects will be exposed to acute (one day) and chronic (seventy days) oral sucralose ingestion. After acute or chronic exposure, volunteers will undergo into an Oral Glucose Tolerance Test (OGTT), taking blood samples at -15, 0, 15, 30, 45, 60, 75, 90, 105, 120 and 180 minutes, respectively. Areas under the curve (AUC) for insulin and glucose, will be calculated from zero to one hundred and eighty minutes as described; for C peptide, glucagon, GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide) measure points will be at 0, 30 and 60 minutes only. Differences between one and seventy days AUC means will be compared between the three groups, adjusting for BMI. Besides, initial and final systemic inflammatory markers and inflammatory monocytes levels will be quantified and compare between acute and chronic exposure. Also, a comparison between the percentage of acute and chronic microbiome bacterial population in feces will be made.

Bioequivalence Study of Tetrabenazine Tablets 25 mg Under Fed Conditions

Start date: December 2015
Phase: Phase 1
Study type: Interventional

This is an open-label, randomized, four-period, two-treatment, two-sequence, balanced, single dose, crossover, oral bioequivalence study in healthy, adult, human subjects under fed conditions.

NCT ID: NCT03702673 Not yet recruiting - Healthy Clinical Trials

Compare the Pharmacokinetic of K-877 Controlled Release (CR) and Immediate Release (IR) Tablets in Healthy Adults.

Start date: October 5, 2018
Phase: Phase 1
Study type: Interventional

A study to compare the pharmacokinetics of 3 types of K-877 controlled release tablets with a current normal K-877 tablet in healthy adult subjects.

NCT ID: NCT03700892 Recruiting - Healthy Clinical Trials

In-vivo Effects of E-cigarette Aerosol on Innate Lung Host Defense

Start date: October 2018
Phase: N/A
Study type: Interventional

While e-cigs are commonly represented as safer alternatives to tobacco cigarettes, little is known regarding the health effects of their short- or long-term use. The responses and the e-cig components exerting these effects on the airways are largely unknown. This study will identify if specific e-cig flavors modify respiratory immune responses. This study will determine the effects of cinnamaldehyde (CA)-containing e-cigarettes on airway epithelial cell ciliary function (i.e., MCC) in humans. Additionally the study will determine the effects of CA-containing e-cigarettes on airway immune cells obtained through induced sputum (SI) after inhalation of CA-containing e-cig aerosols to determine CA-induced effects on a) immune cell function (e.g., phagocytosis, respiratory burst), b) immune cell surface phenotype, and c) mediator production in humans in vivo.

Exosome Proteomics to Detect EPO

Start date: October 15, 2018
Phase: N/A
Study type: Interventional

The role of exosomes in cell signalling has only recently been appreciated and is a hugely exciting and rapidly growing area, and combined with LC-MS/MS proteomics, can overcome traditional barriers to proteomics in doping applications. To our knowledge, no research has yet been undertaken to explore whether the highly promising combination of exosome proteomics has utility for rhEPO detection. The applications are extensive; the diagnostic value of differentially regulated proteins could be further validated against the existing IEF EPO WADA accredited tests using samples collected during this study, used to study altitude hypoxia versus exogenous EPO administration (WADA current targeted research 2017), investigated as a platform approach to ESA and HIF agents more generally, as well as facilitate development of direct ELISA high throughput tests.

Post Hoc Analysis and Clinical Data Collection for Subjects Tested With Brain Network Activation (BNA™) Technology

Start date: May 1, 2018
Study type: Observational

The study is designed to collect data that will aid in future scientific and engineering exploration of correlations between clinical assessments and BNA scores. The results are primarily intended for scientific inquiry and engineering development purposes, and may be used in future regulatory submissions.

Creatine Kinase Levels and Clinical and Functional Parameters in Parajiu-jitsu Athletes

Start date: September 20, 2018
Phase: N/A
Study type: Interventional

Introduction: Evidence indicates that muscle damage caused by exercise can lead to functional, biochemical and clinical damage. Therefore, it is pertinent to perform investigations related to the muscle damage marker, creatine kinase with clinical and functional responses. These outcomes encompass an intrinsic potential for understanding the real magnitude of interpretation of classic signals in athletic environments and monitoring of athletes, contributing to specific actions. Objective: To verify the correlation between clinical signs (pain and perception of recovery), functional (muscular strength) and the behavior of CK levels, in the moments following a simulated fight. METHODS: Six male parajiu-jitsu practitioners (34-44 years) were included in the study. The participants attended the collection site 4 times, with a 24-hour interval between sessions, characterizing the following collection moments: baseline, post-exertion, 24, 48 and 72 hours after the simulated fight. Data on pain (visual analogue scale - EVA), perception of recovery (Likert Scale), muscle strength (Dynamometry) and blood samples for CK analysis were collected. All parameters described were measured at all times of collection. For the analysis of the association between behavior of CK levels, clinical and functional variables, the Odds Ratio test and 95% confidence interval were used. For the gross values, the Pearson test was used according to the normality of the data.

NCT ID: NCT03698344 Recruiting - Healthy Clinical Trials

Sympathetic Nerve Response Incited by Biodiesel Exhaust Exposure

Start date: October 8, 2018
Phase: N/A
Study type: Interventional

The adverse effects of current ambient air pollution on cardiovascular and respiratory health have been demonstrated in an extensive series of epidemiological, observational and experimental studies. Similar cardiovascular responses seen post diesel exposure have been shown to occur following biodiesel exhaust exposure as well. In the current project the investigators aim to determine whether an acute exposure to biodiesel exhaust (rapeseed methyl ester) causes impacts on sympathetic nervous system activation in healthy volunteers.
