Filter by:Our objective is to determine the metabolic availability of Lysine in white maize using the indicator amino acid oxidation (IAAO) technique in adult men.
Very low dose (VLD) cyclobenzaprine at bedtime has shown promise as a treatment for fibromyalgia, but the chemistry of cyclobenzaprine requires new formulation technology for bedtime use. The present trial is designed to assess the safety and tolerability of 3 different formulations of TNX-102 2.8 mg SL Tablets (a new formulation of cyclobenzaprine designed to result in increased dosage precision and decreased potential for morning grogginess) and to compare the bio-availability of 3 different formulations of TNX-102 2.8 mg SL Tablets (TNX-102 with potassium phosphate, TNX-102-B with sodium phosphate, and TNX-102-C with trisodium citrate) to that of cyclobenzaprine (5 mg tablets).
Oxytocin is a neuropeptide that is well known for its role in social and affiliative behavior in humans. Oxytocin receptors are significantly lowered in autistic individuals and administration of oxytocin has shown benefits in enhancing social recognition and behavior in autistic children. However, more recent research has refined the behavioral effects of oxytocin, moving away from the notion that the neuropeptide blindly induces love and trust, towards the view that it actually increases social perception in assessing friend vs. foe: supporting cohesion with 'insiders' and distrust and aggression for 'outsiders.' Oxytocin is responsible for the selective aggression shown by lactating female mammals protecting their young, an effect demonstrated also in humans, and has been shown to strengthen feelings of ethnocentrism. However, no neuroimaging study to date has investigated this effect, with the consequence that its neurobiological basis is still unknown. The general aim of our study is to determine meso-circuit brain dynamics that underlie oxytocin's amplification of both trust and aggression; and specifically, using neuroimaging (fMRI, magnetoencephalography, and behavioral testing) whether oxytocin amplifies kinship bias by attenuating social reward learning.

The purpose of this study is to determine whether copeptin levels are affected by food intake.
A major advantage of understanding a neural control scheme is able to simultaneously perform multiple tasks based on the Uncontrolled Manifold (UCM) hypothesis by taking advantage of motor redundancy. The present study aims to investigate this hypothesis further by examining the effect of artificially eliminating knee and lumbar-thoracic joint motions on postural control when the arms performing targeting task simultaneously in standing. Subjects (Younger group: 20~35 years old; Elder group: 60~85 years old) will execute a targeting task with and without an additional ball-balancing task in standing with free joint motions and with restricted joint motions. The investigators expect to recruit 50 subjects for each group. Analyses of joint configuration variance on the stability of the center of mass (COM) position and the hand path will be performed using the UCM method of variance analysis. This method partitions joint configuration variance into one component consistent with the use of motor abundance and a component that leads to COM position or hand path variability. Furthermore, the differences between the younger group and the elder group will be evaluated.
Very low dose (VLD) cyclobenzaprine at bedtime has shown promise as a treatment for fibromyalgia, but the chemistry of cyclobenzaprine requires new formulation technology for bedtime use. The present trial is designed to assess the safety and tolerability of TNX-102 2.4 mg SL Tablets (a new formulation of cyclobenzaprine designed to result in increased dosage precision and decreased potential for morning grogginess) at 2.4 mg and 4.8 mg and to compare the bio-availability of TNX-102 2.4 mg SL Tablets at 2.4 mg and 4.8 mg to that of TNX-102-A 2.4 mg SL Tablets (without phosphate) at 2.4 mg and cyclobenzaprine (5 mg tablets).
Very low dose (VLD) cyclobenzaprine at bedtime has shown promise as a treatment for fibromyalgia, but the chemistry of cyclobenzaprine requires new formulation technology for bedtime use. The present trial is designed to assess the safety and tolerability of sublingual TNX-102 2.4 mg (a new formulation of cyclobenzaprine designed to result in increased dosage precision and decreased potential for morning grogginess) at pH 3.5 and 7.1 and to compare the bio-availability of sublingual TNX-102 2.4 mg at pH 3.5 and 7.1 and cyclobenzaprine (5 mg tablets, or 2.4 mg iv).
The main purpose of the study is to assess the effect of water intake on the formation of 4-ABP DNA adducts.
This study is simply to test the repeatability of the indirect calorimetry instrument the investigators use for our clinical studies.
The primary objective of this investigation is to determine the relative percentage and rate of incorporation of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and total omega-3 (n-3) fatty acids after ingestion of 4 emulsified flavored triglyceride fish oil supplements versus an encapsulated triglyceride in defined plasma lipid pools. The primary endpoints to be evaluated include the fatty acid composition of plasma lipids before and after consumption of a single dose of emulsified triglyceride based fish oil and triglyceride of similar n-3 compositions in capsule form. The investigators will measure changes in plasma phospholipid, and chylomicron fatty acids.
