Serotonin (5-HT) synthesis in neurons is initiated by hydroxylation of the essential amino acid tryptophan. Treatments that raise the level of tryptophan in the brain can rapidly alter the rate at which it is converted to 5-HT. This paper compares the effect of 1, 2 and 3 g L-tryptophan administered
OBJECTIVE
Gut hormones such as cholecystokinin (CCK) and glucagon-like peptide-1 (GLP-1) play a role as satiation factors. Strategies to enhance satiation peptide secretion could provide a therapeutic approach for obesity. Carbohydrates and lipids have been extensively investigated in relation to
Eight subjects, aged 26 to 50 years, who had long histories of carbohydrate (CHO) craving and were more than 45 kg above desirable body weight participated in a randomized, double-blind, crossover pilot study on the effects of L-tryptophan on weight loss and mood state. One g of tryptophan with 10 g
We assessed the plasma amino acids, glucose, and insulin responses of obese and lean control subjects to midafternoon carbohydrate snacks. After a standard 400 kcal lunch, eight lean and nine obese subjects received, at 2PM, a 30 g sucrose snack; blood samples were obtained at hourly intervals until
5-Hydroxytryptophan (5-HTP) is the precursor of the neurotransmitter serotonin and has been used for the treatment of various diseases such as depression, insomnia, chronic headaches, and binge eating associated obesity. The production of 5-HTP had been achieved in our previous report, by the
Proteins have been demonstrated to reduce food intake in animals and humans via peripheral and central mechanisms. Supplementation of a dietetic regimen with single or mixed amino acids might represent an approach to improve the effectiveness of any body weight reduction program in obese subjects.
The objective of this study was to confirm the effect of maternal genistein exposure on body weight of male offspring and the metabolic alterations associated with maternal genistein-induced obesity. Pregnant female Sprague-Dawley (SD) rats were supplemented with 300 mg/kg diet of genistein (GEN) or
Treatment of extreme obesity with jejunoileostomy was followed by a decreased level of S-tryptophan; permanently low concentrations were recorded postoperatively in 29 out of 52 patients. Patients in the low tryptophan group had a higher rate of weight loss and a hgiehr incidecnce of electrolyte
Polycystic ovary syndrome (PCOS) is an endocrine and metabolic disorder in women of reproductive age. Some studies have investigated metabolic alterations in plasma and follicular fluid (FF) from PCOS patients, but they did not control for obesity or insulin resistance (IR); additionally,
OBJECTIVE
The calcium-sensing receptor (CaSR), the major sensor of extracellular Ca2+, is expressed in various tissues, including the gastrointestinal tract. Although the essential ligand of CaSR is calcium, its activity can be regulated by aromatic L-amino acids. The expression of CaSR on
OBJECTIVE
Obesity is linked to metabolic diseases characterized by insulin resistance, such as diabetes and cardiovascular disease. In this study, we investigated the metabolic disorders of uncomplicated obesity to identify early alterations in biological systems.
METHODS
Metabolic differences
OBJECTIVE
To determine if the slope of the amplitude/stimulus intensity function (ASF) of the N1/P2 component of the auditory evoked potential was increased in women with type 2 diabetes reflecting a low brain serotonergic activity in the auditory cortex.
METHODS
In a comparative study in women with
Cellular metabolic networks should be carefully balanced using metabolic engineering to produce the desired products at the industrial scale. As the precursor for the biosynthesis of the neurotransmitter serotonin, 5-hydroxytryptophan (5-HTP) is effective in treating a variety of diseases, such as
Alyteserin-2a (ILGKLLSTAAGLLSNL.NH2 ) stimulated the rate of insulin release from BRIN-BD11 clonalβ cells at a concentration of 30 nm (p < 0.05) with a response of 296 ± 26% of basal release at 3 μm (p < 0.001). The insulinotropic actions of analogs containing substitutions by l-lysine, d-lysine, or
The peroxisome proliferator-activated receptors (PPARs) related to regulation of lipid metabolism, inflammation, cell proliferation, differentiation, and glucose homeostasis by controlling the related ligand-dependent transcription of networks of genes. They are used to be served as therapeutic
