NCT06834295
The goal of this clinical trial is to assess how the body processes, breaks down and removes a new test medicine (vapendavir) from the body in healthy male participants.The main question it aims to answer is how the body handles the test medicine. In order to do that, the test medicine will be radiolabeled to track the test medicine in the body. Healthy male participants who meet entry criteria will be admitted to the clinic for a duration of approximately 9 days (Day -1 to Day 8). Participants will be admitted in the evening on the day before dosing (Day -1). Participants will take a single oral dose of radiolabeled vapendavir on Day 1 and have samples collected and safety tests completed during various times throughout their stay in the the clinic. The safety tests will provide additional information on the safety and tolerability of the test medicine.
NCT01367561
This is a double-blind, randomized, study at a single clinical site investigating the effect of methylnaltrexone and naloxone versus placebo in healthy males who have received a short-acting opioid, remifentanil.
NCT05294198
There is no evidence that beetroot extract (Beta vulgaris L.) is advantageous for the recovery of cardiovascular parameters and the autonomic nervous system (ANS) after submaximal aerobic exercise. The objective of this study is to evaluate the effect of beetroot extract supplementation on the recovery of cardiorespiratory and autonomic parameters after a submaximal aerobic exercise session. Healthy male adults will perform a cross-over, randomized, double-blind, and placebo-controlled trial. Beetroot extract (600mg) or placebo (600mg) will be ingested 90 minutes before evaluation in randomized days. Systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), mean arterial pressure (MAP), heart rate (HR), and HR variability (HRV) indexes will be recorded at Rest and during 60 minutes of recovery from exercise.
NCT00777543
The aim of the present study is to investigate the effect of pretreatment of bran on improving the bioavailability of ferulic acid in wholegrain breads containing bran. As secondary endpoints we will investigate the changes in plasmatic antioxidant capacity, anti-inflammatory effects, colonic metabolites from ferulic acid and short chain fatty acids (SCFA).
NCT01943266
Minimal data are available on protein requirements throughout the lifespan. Currently available recommendations are based on nitrogen balance data. The limitations of the nitrogen balance method have been well described. Importantly, nitrogen balanced underestimates requirements. The current dietary reference intakes (DRI) requirement for healthy adult males is based on the reanalysis of the nitrogen balance date from Young and Scrimshaw. This data was reanalyzed statistically by Rand et al. and he concluded that the protein requirement of healthy adults was 0.65 and 0.83 (mean and RDA) g/kg/day of good quality protein. Using indicator amino acid oxidation (IAAO), our group estimated the protein requirement of young men (mean age 27 years) to be 0.93 and 1.2 g/kg/day (mean and RDA). Currently there are no studies on protein requirement in the elderly. In a recent nutrition survey conducted by national health and nutrition examination survey (NHANES), the authors concluded that adults between the ages of 51 - 70 years old consumed an average on 1.0 g/kg/day (ideal body weight) of protein which represents about 15 % of calories. Depending on the calculations used for ideal body weight some older adults could be getting higher or lower than requirement. There is no scientifically derived protein estimate for older adults. Therefore there is a need to measurer protein requirement in that population. The goal of this study therefore is to measure the protein requirement of male elderly subjects between the ages of 65 - 75 years using the IAAO technique.
NCT02166164
In this prospective trial we aim to investigate the intra-individual and inter-individual variance in secondary hyperalgesia following pain elicited by the experimental pain model: Brief Thermal Sensitization. Furthermore we wish to investigate how precise the psychological tests, Pain Catastrophizing Scale and Hospital Anxiety and Depression Scale predict the size of the area of secondary hyperalgesia.
NCT01215292
The purpose of this research study is to determine how much male hormone, testosterone, is necessary to maintain sperm production in the testis. This knowledge will be used to help in the development of a safe male hormonal contraception. Specific Aims: 1. to determine if ketoconazole plus acyline will suppress intratesticular testosterone(ITT) to a greater degree than acyline alone. 2. to determine if dutasteride plus acyline will suppress intratesticular dihydrotestosterone (IT-DHT) to a greater degree than acyline alone. 3. to determine if anastrazole plus acyline will suppress intratesticular estradiol(IT-E2) to a greater degree than acyline alone.
NCT00782392
We are developing an oral supplement of carbohydrates to be added to infant formulas in order to improve brain development, immune function, and overall health of infants and children. After a careful review of what is known about these sugars, there is very little information regarding their use in infants and children, although there is some information in adults and animals. Many of these sugars have been used in a glyco-nutritional supplement in adults and children, with minimal or no reported side effects. We are developing a custom blend of important individual sugars, and need information regarding their dosing and blood concentrations following oral intake of the carbohydrate supplement. Timed blood samples following the carbohydrate supplement will provide us with a better understanding of the most effective dose and the metabolism of these sugars in adults. This will give us the preliminary information we need for developing an oral supplement of special sugars that can be added to infant formulas to help improve brain development and immune function in infants and children.
