Valine and leucine, the branched-chain amino acids ([BCAA.sub.S]) participating in blood glucose regulation, were found to be signicantly increased in male and female rats within exhaustive exercise.
In above mentioned human studies, this position appeared non-synonymous similar to our samples, but in human studies it appeared as frame shift point mutation, while in our dogs' samples, it changed the valine residue to phenylalanine amino acid.
According to the need for biomarkers of AD specially in blood samples which has a less invasive method than collecting CSF fluid, also a serum metabolite marker panel was prpoposed for the detection of AD, including alanine, glutamine, serine, valine, isobutyrate, carnitine, taurine, pantothenate, glucose, asparagine, succinate, glycine, creatinine, isoleucine, pyruvate, betaine, choline, scyllo-inositol and myo-inositol.

This study was conducted to determine the effects of altering the SID valine:lysine ratio on the performance and amino acid metabolism of 144 crossbred (Duroc x Landrace x Large White) pigs weaned at 28 [+ or -] 4 days of age and weighing 8.79 [+ or -] 0.02 kg body weight.
The increases for T2DM in leucine, isoleucine, valine, and 3-HIB were significant after BMI adjustment, but those in tyrosine and phenylalanine were not.
The amino acid profile revealed an isoleucine level of 5.9 [micro]mol/L, leucine of 1166 [micro]mol/L, and valine of 159 [micro]mol/L.
Following initial decompensation attack, medical supportive treatments were used during increases in blood leucine, valine, and isoleucine levels during infections for 19 months' follow-up period.
(4,12) Between 70% and 90% of BRAF mutations involve a single base transversion (T>A) in exon 15, which results in the substitution of glutamic acid for valine at amino acid position 600 (BRAF V600E) (Figure 3).
The effects of GanedenBC 30 with protein were examined in a random double blind crossover clinical trial on key amino acids including leucine (the regulator for muscle protein synthesis), isoleucine and valine (branched chain amino acids), as well as histidine, alanine, asparagines, citrulline, cystine, glutamine (a key amino acid for supporting ph balance and the immune system), methionine, ornthinine, serine, threonine, tryptophan and phenylalanine.
Usually, studies conducted to evaluate the reduction in crude protein by means of amino acid supplementation use only L-Lysine, DL-methionine, L-threonine and L-tryptophan, but, progressive CP reduction in diets may lead to a situation in which other amino acids, such as arginine, valine and isoleucine, act as limiting factors for improved performance (Peganova & Eder, 2002).
