Under physiological conditions insulin controls the metabolism of carbohydrates, lipids and proteins. Diabetes mellitus is a metabolic disease characterized by disturbance in intermediary glucose glucose-induced release. Arginase (L-arginine amidinohydrolase, EC 3.5.3.1) modulates nitric oxide synthase activity regulating intracellular L-arginine availability. In diabetes mellitus, decrease bioavailability central mechanism for endothelial dysfunction. The aim our study was to assess...

Autonomic dysfunction is an emerging non-traditional cardiovascular risk factor that correlates with obesity, components of metabolic syndrome, as well cardiorespiratory fitness. As a simple and validated index autonomic balance, heart rate recovery (HRR) has been reported useful biomarker for predicting morbidity mortality.The aim this study was to compare HRR in metabolically healthy vs. unhealthy obese children.A total 56 children whom 31 had syndrome were examined. All the participants...

Sufficient intake of folic acid is necessary for normal embryogenesis, fetal, and neonatal development. Folic facilitates nucleic internalization, protects cellular DNA from nuclease degradation. Human milk contains enzymes, antimicrobial proteins, antibodies, along with macrophages, that protect against infections allergies. However, little to no information available on the effects supplementation degradation acids in human milk. In present study, we aimed determine RNase activity (free...

Abstract The need for sufficient quantities of folic acid normal embryogenesis and fetal development is well known. Women childbearing age must be sure to have an adequate intake periconceptionally prior during pregnancy. Folate plays essential role in the biosynthesis RNA DNA, phospholipid neurostransmitters synthesis, using S-adenosylmethionine (SAM) as primary methyl group donor. In some countries, knowledge that preventable reduction risk neural tube defects (NTD) lowering high amount...

Arginase (L-arginine amidinohydrolase, EC 3.5.3.1) is the key enzyme in urea synthesis, hydrolyzing L-arginine into L-ornithine and urea. modulates levels of nitric oxide, creatine, creatinine, likely by regulating intracellular availability. The objective present study was to determine arginase activity concentration creatinine colostrum mature human milk obtained from nursing mothers. Our longitudinal biochemical analyses show that activities concentrations were highest at first day...

Abstract Folic acid, or folates are available from a large variety of sources, such as green leafy vegetables (spinach, beans) and liver. The importance is based on their requirement coenzymes in the transfer utilization one-carbon units biosynthetic reactions. Folate an essential cofactor for de novo biosynthesis purine nucleotides thymine, thus influencing RNA DNA synthesis. Therefore, during periods rapid cell regeneration growth, pregnancy infancy, increased amounts folate required. has...
