OBJECTIVE To determine how weight for gestational age affects urea and mineral excretion by preterm infants receiving total parenteral nutrition (TPN). STUDY DESIGN Daily urine samples were collected from all preterm infants given high calcium TPN, providing 30 kcal/g amino acids, during its first 44 months of use, and from all those given standard TPN, providing 25 kcal/g amino acids, over t...
BACKGROUND We undertook this study to test the hypothesis that perioperative total parenteral nutrition (TPN) decreases the incidence of serious complications after major abdominal or thoracic surgical procedures in malnourished patients. METHODS We studied 395 malnourished patients (99 percent of them male) who required laparotomy or noncardiac thoracotomy. They were randomly assigned to rec...
Between amateur passions and a professional academic agenda. The Society of the Friends Learning in Przemyśl as publishing center before 1939 article discusses activity (TPN) from its establishment 1909 until outbreak Second World War 1939. Publishing works was one TPN statutory goals beside e.g. running museum, library, an archive, conducting archaeological work promoting various fields knowle...
We report a patient with severe anorexia nervosa, treated with temporary total parenteral nutrition (TPN), in whom reversible hyperintensity of the anterior pituitary gland was seen on T1-weighted MR images. The anterior pituitary was isointense with white matter before TPN therapy and became markedly hyperintense after 3 months of treatment. The intensity normalized after TPN therapy was disco...
1. Purified alkaline phosphatases from cow's milk and calf intestinal mucosa quantitatively convert TPN into DPN. DPN is not hydrolysed by either enzyme. 2. These results confirn that the third phosphate grouping of TPN is esterified (to ribose), since the action of both purified phosphatases is restricted to phospho mono-esters and amides. 3. Under the experimental conditions used, there was n...
A method is described for determining TPN+ and TPNH in a single tissue homogenate made in dilute NaOH at 0’. One portion, for TPN+, is acidified after adding ascorbic acid to prevent TPNH oxidation. A second portion, for TPNH, is heated (still alkaline) after adding cysteine to prevent oxidation. If desired, a third portion can be analyzed directly without heating for total TPN (TPN+ plus TPNH)...
BACKGROUND ATP-sensitive potassium (K(ATP)) channel openers provide cardioprotection in multiple models. Ion flux at an unidentified mitochondrial K(ATP) channel has been proposed as the mechanism. The renal outer medullary kidney potassium channel subunit, potassium inward rectifying (Kir)1.1, has been implicated as a mitochondrial channel pore-forming subunit. We hypothesized that subunit Kir...
OBJECTIVE Hyperglycemia may increase mortality in patients who receive total parenteral nutrition (TPN). However, this has not been well studied in noncritically ill patients (i.e., patients in the nonintensive care unit setting). The aim of this study was to determine whether mean blood glucose level during TPN infusion is associated with increased mortality in noncritically ill hospitalized p...
Background: Riboflavin, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) are cofactors in oxidation-reduction reactions. The aim of this study was to compare a direct high performance liquid chromatography (HPLC) method with an indirect enzymatic method to assess flavin status and establish reference intervals. The HPLC method was used to assess prevalence of flavin deficiency ...
Tapasin (tpn), an essential component of the MHC class I (MHC I) loading complex, has a canonical double lysine motif acting as a retrieval signal, which mediates retrograde transport of escaped endoplasmic reticulum (ER) proteins from the Golgi back to the ER. In this study, we mutated tpn with a substitution of the double lysine motif to double alanine (GFP-tpn-aa). This mutation abolished in...
