Zinc may be absorbed from diet via zinc transporter mediated pathways, or, when coupled with amino acids, via amino acid transporter pathways. When zinc is coupled with amino acids in diet, it may dissociate from those amino acids in the acidic environment of the stomach prior to entering the small intestine. An experimentally-determined value for any pre-absorptive dissociation of zinc from a zinc amino acid complex (ZnAA) is necessary for the accurate compartmental modeling o...
Assessment of the impact of oral Human Milk Oligosaccharides (HMO) application on acute diarrhoea and the development of prolonged and persistent diarrhoea in paediatric patients hospitalized with acute diarrhoea.
Alterations of acid-base equilibrium are very common in critically ill patients and understanding their pathophysiology can be important to improve clinical treatment.
This study of the tolerance and acceptability of an amino acid based feed will assess gastrointestinal (GI) tolerance, product intake and acceptability in relation to taste, smell, texture in 20 patients between 1-10 years currently using or requiring an amino acid based feed for the dietary management of Cows' Milk Allergy and food-allergy-associated conditions, over 4 weeks.
Protein requirements in individuals who participate in endurance-based exercise training have been suggested to be greater than the current recommended dietary allowance (RDA). The biological value of protein depends on the amino acid composition. As liebig's law of the minimum, the protein synthesis is limited due to the lack of single rate limiting amino acid. In this case, the first rate limiting amino acid determines protein intakes to maximize the protein synthesis. Addin...
The aim is to assess the impact of physical inactivity on muscle amino acid balance. In addition, we will evaluate how the diet and/or a pharmacological intervention designed to manipulate lipid metabolism (acipimox) will modulate muscle amino acid balance.
In a recent randomized, double-blind, cross-over clinical trial, serum growth hormone (hGH) increased 682% above baseline 120 minutes after oral administration of an amino acid-based dietary supplement (SeroVital), p=0.01 vs placebo. In contrast to the mechanism of hGH stimulation by ghrelin, we hypothesize that the supplement suppresses somatostatin, a know inhibitor of both hGH and TSH. To test this hypothesis, we measured triiodothyronine (T3) after administration of the ami...
This is a safety and tolerability study investigating the effect of an amino acid formulation in healthy volunteers during and after limb immobilization.
Nutritional requirements for dietary amino acids in children have traditionally been determined utilizing the nitrogen balance technique, which is prone to underestimating protein requirements. As a result, there is a need to re-evaluate recommendations in order to characterize how dietary amino acid needs may be modulated by physical activity in healthy, active children. The purpose of this study is to measure the protein requirement in children (boys and girls) using the IAAO...
MRI is used in clinical routine for diagnosing brain tumors, but has limitations in identifying tumor grade, true tumor extension and differentiate viable tumor tissue from treatment induced changes and recurrences. Amino acid PET has demonstrated a great potential for defining true tumor volume, differentiate viable tumor tissue from postoperative changes or radiation necrosis, selection of biopsy site, non-invasive grading of gliomas and for treatment planning and therapy ...
The objective of this study was to evaluate the effects of supplementary antioxidant therapy on the levels of biomarkers and inflamatory citocines in patients with a previous history of non-melanoma skin cancer treated with surgery. This was a double-blind, randomized, placebo-controlled trial. Patients were randomized into two groups, one receiving placebo (n=34) and the other receiving supplementary antioxidant therapy (n=26) with vitamin C (50 mg), vitamin E (60 mg), and zin...
To assess the frequency and nature of adverse events in infants fed a free amino acid based infant formula.
Phenylalanine and tyrosine are aromatic amino acids that people need to obtain in their diets. Amino acids are the building blocks for protein, are are therefore required to form tissues in the body. It is well known that pregnant women require more protein in their diets, but the exact amount for each amino acid is undetermined. To find out how much of phenylalanine and tyrosine pregnant women require, the investigators plan to study pregnant women in early and late gestation ...
Dietary amino acid supplementation may provide an effective means to promote tendon injury recovery and enhance collagen synthesis. While most published research has been completed in animal models, research with young adults has shown that a leucine-rich whey isolate consumed during a chronic resistance training (RT) intervention resulted in greater gains (~60%) in tendon CSA when compared to placebo. Leucine-rich diets have also improved tendon collagen content in rodents. Fu...
Objective: The study aimed to assess the effect of topical application of an amino acid + sodium hyaluronate acid gel after lower third molar extraction. Study design: 136 patients requiring lower third molar extraction were enrolled. An amino acid + sodium hyaluronate acid (HA) gel was applied to the sockets of the patients in the treatment group immediately following extraction; the sockets of the controls were simply flushed with a sterile saline solution. 7 and 14 days aft...
Adjuvant N-methyl-D-aspartic acid (NMDA)-enhancing agents, such as GlyT-1 inhibitors and NMDA-glycine site agonists have been demonstrated to be beneficial for chronic schizophrenia patients. The purpose of this study is to evaluate efficacy and safety of add-on treatment of an inhibitor of D-amino acid oxidase (DAAOI), DAAOI-1, in chronically stable schizophrenia patients who have been stabilized with antipsychotics.
ATP is generated mainly through anaerobic metabolism during strenuous exercise, which is then followed by the generation of lactic acid. However, this process can only be maintained for a short time, approximately one minute, because the accumulation of lactic acid in the muscles may affect muscle performance. The efficiency of lactic acid metabolism is one of the most important reasons for endurance improvement. The purpose of this study was to evaluate the impacts of the dail...
This protocol seeks to define aspects of intestinal and hepatic uptake and metabolism of several amino acids. The major hypothesis to be tested is that the splanchic bed (intestine and liver) conserves essential amino acids and metabolites while synthesizing and metabolizing nonessential amino acids. The aims of the study include defining the relative roles of enteral and hepatic extraction/metabolism in the disposition of glutamate, alanine, methionine and other amino acids....
This pilot study will examine the benefit of this amino acid based hydration solution in patients with IBD who have undergone a total colectomy and have either ileostomies or jpouches. Findings from this study and possible future studies could have broad implications for patients with malabsorption resulting from many underlying conditions, including IBD.
To observe the effects of an amino acid-based formula on symptoms associated with food allergies in infants.
The aim of the study is to compare intradialytic plasma kinetics of amino acids after administration per os of Renoral or intravenous administration of amino acids in patients with end-stage renal disease treated with hemodialysis maintenance.
A single-centre, two-arm, parallel randomised controlled trial (RCT) to compare the combined effect of early intravenous bolus amino acid supplementation and mobilisation versus standard of care on changes in muscle mass over the first week in ICU. Half of study participants will receive the study intervention (in-bed cycling followed by an intravenous bolus amino acid supplement), while the other half will receive standard of care only.
Background: Adverse childhood experience have been described in sexual offenders but the link with the offence need to be further investigated. Investigators postulate that one of the clinical moderating factors could be dissociative experience, a consequence of these early adverse experiences reactivated during the offence. The purpose of the study is to estimate the prevalence of clinical dissociation during the offence in a male adult population referred to our center for a ...
