phenylketonurias/アルブミン

The role of oxidative stress in the pathogenesis of phenylketonuria (PKU)-associated disorders has been implicated. Ischemia modified albumin (IMA) is a modified form of serum albumin, which is produced under the conditions of oxidative stress. The aim of this study was to measure the serum level of

OBJECTIVE Strict low-phenylalanine diet is associated with an increased risk of developing micronutrient deficiencies in patients with phenylketonuria (PKU). The primary objective of this single-center, case-control study was to assess the nutritional parameters of patients with PKU on strict

OBJECTIVE We reviewed records of 41 children with treated phenylketonuria (PKU) in order to evaluate hematopoiesis and the effect of iron and protein sufficiency. RESULTS Six children (15%) were found to have anemia. Combined depletion of iron and protein stores was most likely to result in anemia,

OBJECTIVE To evaluate the efficacy and safety of a phenylalanine-free amino acid-based enteral formula (AA-PKU2) in the treatment of children with phenylketonuria (PKU) aged 1-8 years. METHODS A prospective, open, self-controlled, multi-center trial was performed, enrolling 121 PKU children (1-8

OBJECTIVE To examine whether a phenylalanine-free protein substitute with prolonged release may be beneficial to the protein status of children with phenylketonuria (PKU) compared to conventional substitutes. METHODS Sixty children with PKU, 7 to 16 years of age, were randomly allocated to receive

OBJECTIVE To determine the effect of differences in plasma phenylalanine (Phe) concentrations (< 363 umol/L, 363 to 605 umol/L, and > 605 umol/L) on hematological and immunological parameters in 22 children with phenylketonuria (PKU). METHODS Children with PKU were divided into one of three groups

BACKGROUND In phenylketonuria (PKU), protein substitute is an essential part of dietary treatment. Short-term studies have demonstrated that liquid protein substitutes (LPS) are efficacious, and improve compliance in teenagers and adults with PKU, although there are no data available to demonstrate

Phenylketonuria is an inherited disorder of metabolism of the amino acid phenylalanine caused by a deficit of the enzyme phenylalanine hydroxylase. It is treated with a low-protein diet containing a low content of phenylalanine to prevent mental affection of the patient. Because of the restricted

To elucidate the mechanism and biologic significance of urinary occurrence of N-acetylphenylalanine in phenylketonuria, the metabolic fate of N-acetylphenylalanine was studied in rats. In vivo and in vitro analysis revealed that N-acetyl-14C(ul)-phenylalanine bound to plasma albumin with an

OBJECTIVE The objectives of this study were to determine if Phenex-1, amino-acid modified medical food with iron maintained normal indices of protein status in infants with phenylketonuria (PKU) and to investigate factors that influence plasma amino acid concentrations. METHODS A study was conducted

Children with phenylketonuria (PKU) obtain a great deal of their protein and mineral intakes from synthetic elemental formulae devoid of phenylalanine. To assess the effect of such diets and/or the disease on bone mineralization, children with PKU were compared to normal children for many parameters

HNF1 is a transcriptional activator of many hepatic genes including albumin, alpha1-antitrypsin, and alpha- and beta-fibrinogen. It is related to the homeobox gene family and is predominantly expressed in liver and kidney. Mice lacking HNF1 fail to thrive and die around weaning after a progressive

Amino acid mixtures (AAM) are protein substitutes used for phenylketonuria treatment, but their metabolic effects have not been well characterized. The objective of this study was to compare the acute glycemic response to free amino acids (free AA) from AAM with the response to intact protein

BACKGROUND Subjects consuming protein-restricted diets, such as patients with phenylketonuria (PKU) or milder hyperphenylalaninemias (HPAs) are at risk of selenium deficiency. Selenium is a cofactor of the antioxidant enzyme glutathione peroxidase and of the thyroid hormone converting enzyme

Recent studies have shown that nondividing primary cells, such as hepatocytes, can be efficiently transduced in vitro by human immunodeficiency virus-based lentivirus vectors. Other studies have reported that, under certain conditions, the liver can be repopulated with transplanted hepatocytes. In
