The study will be conducted in a Phase 1 unit with sufficient facilities to house subjects as required by the protocol.
The objectives of this study are the following: 1) to determine the acute effect of whole grain barley on risk factors of cardiovascular disease compared to a diet low in whole grain, and 2) to compare the effects of whole grain barley to those of whole grain oats to determine if the response to these two grains is similar.
The purpose of this study is to investigate the effects of the dietary supplement oréVida™ (active ingredient on the basis of a culinary herb)administered twice daily in an acute study on an improvement in vigilance, attention, concentration, memory and mood in 45 healthy men and pre-menopausal women, aged 35-50 years, inclusive. oréVida™ is considered a dietary supplement, and therefore it is not an approved drug by the Food and Drug Administration (FDA). It is regulated like a food. The U.S. Food and Drug Administration does not strictly regulate herbs and dietary supplements. We do not claim that this supplement is meant to treat any ailment.
The primary objective of this trial is to determine whether two doses of an extract from bran demonstrate a prebiotic effect on colonic bacteria (by modulating selected fecal microbial populations, particularly bifidobacteria). The secondary objective is to measure the potential beneficial effects of consuming an extract from bran on the following physiological parameters: laxation, fecal pH, fecal moisture and stool consistency, blood glucose and insulin concentrations, plasma lipid profiles and serum free fatty acids, colonic bacterial short chain fatty acid production, ammonia metabolism and protein degradation, and biomarkers of oxidative stress and inflammation.
This study will define the effects of ferumoxytol on electrocardiogram (ECG) data as well as evaluate pharmacokinetics
As the seasons change during the course of the year, many animals show major changes in their behavior and physiology. Many of these changes are triggered by changes in the length of time each night that the pineal gland produces the hormone melatonin. Melatonin is produced for a longer time in winter when nights are long, than in summer when nights are short. Some researchers believe that melatonin may play a similar role in how season effects mood of patients with seasonal affective disorder. Seasonal affective disorder (SAD) or mood disorder with seasonal pattern is a condition where the normal biorhythm is disturbed during a season, especially autumn-winter. Patients may begin experiencing or experience worsening of depressive symptoms. Patients complain of being constantly tired, craving sugary foods, overeating, and over sleeping. Researchers have collected some preliminary data showing that the duration of nighttime melatonin secretion increases in winter and decreases in summer in healthy women, but not in healthy men. However, men diagnosed with SAD have shown longer duration of melatonin secretion in the winter, similar to the duration seen in healthy women. If these early findings are confirmed it may explain why SAD is more common in women than in men. The purpose of this study is to continue researching the differences in melatonin secretion over the seasons in healthy men and women, and to determine how these findings may apply to patients with SAD.
The objectives of this trial are to assess the effects of corn oil and coconut oil on low-density lipoprotein cholesterol (LDL-C) concentrations, and other aspects of the fasting lipoprotein lipid profile, as well as insulin sensitivity and an inflammatory marker, in men and women.
The purpose of this study will allow us to examine how quickly and to what extent plasma amino acids levels rise after ingesting a single dose of either whey or albumin protein. The investigators anticipate that the amino acids from albumin concentrate protein will rise as quickly and to the same extent as amino acids from whey protein. These findings will help us to understand the biological availability of these proteins and efficacy of the supplement so that consumers may be presented with nutritional options.
The presence of certain ingredients such as sodium and glycerol can facilitate retention of the fluid consumed via renal water reabsorption. To maintain overall whole-body fluid balance, it is important that ingested fluid is retained in the body instead of losing it through urination. The purpose of this study is to determine the effect of sodium and glycerol concentrations at various fluid intake volumes on fluid balance in healthy, euhydrated men and women.
The results of a prior study PEP-2311 suggested there was a positive dose-response effect of glycerol and sodium on fluid balance and fluid retention. In addition, inclusion of glycerol resulted in an upward shift in the relationship between sodium concentration and fluid balance. The practical interpretation is that addition of glycerol enables a reduction in sodium concentration compared with a 0% glycerol drink. In this follow-up study, the investigators hypothesize that 1) fluid balance will be sustained (greater than or not different from baseline) and significantly greater than placebo for 120 min after drinking the test no/low/moderate carbohydrate beverages and 2) fluid balance will not differ between the carbohydrate-electrolyte beverages, but both will be greater than placebo.
The objective of this study is to determine the effect of consumption of drinks with varying amounts of glycerol and electrolytes on fluid balance at rest.
A study to evaluate and compare the PK profiles of abaloparatide-SC 80 μg and abaloparatide-sMTS 300 μg in a cohort of healthy men and to make a similar evaluation in a cohort of healthy women
The objective of this study is to assess the effects of ergothioneine at two doses, compared to placebo, on cognition, mood, and sleep in healthy adult men and women.
The purpose of this study is to determine the effects of antibacterial mouthwash on muscle speed and power in healthy young men and women. We have previously demonstrated that drinking beetroot juice, a source of dietary nitrate and therefore nitric oxide, increases muscle function in this population. Antibacterial mouthwash has been shown to interfere with the conversion of dietary nitrate to nitric oxide. We therefore hypothesize that it will diminish nitric oxide bioavailability and inhibit muscle contractility.
This study will investigate the effect of multiple doses of the strong P450 enzyme inhibitor itraconazole on the pharmacokinetics of Lu AF35700 in healthy subjects.
This is a Phase 1, double-blind, randomized, repeat-dose, single -dite, 4-arm parallel group study to define the ECG effect of lixivaptan using a therapeutic and supratherapeutic dose compared to placebo and moxifloxacin (a positive control in healthy adult men and women.
Women and men consuming a low protein diet may be at risk for bone loss. The purpose of this study is to determine whether a daily protein supplement will improve bone health among healthy older adults.
The purpose is to examine the effects of time-restricted eating (TRE; consuming all calories within an 8-hour period each day) vs. normal eating (CON; consuming same kcals and protein as TRE, but during a 10-13 hr eating window each day) during 8 weeks of resistance exercise on body composition and muscle mass (whole muscle and single fiber), muscular performance, anabolic protein signaling, single muscle fiber characteristics, and the gut microbiome in well-trained young men and women.
The purpose of this study is to determine the safety and tolerability of RN564 in women with osteopenia and healthy men.
This is a two-center, open-label study conducted in healthy male and female volunteers at two academic research centers.
