Total parenteral nutrition (TPN) leads to a decline in phosphatidylinositol 3-kinase (PI3K)/phospho-Akt (p-Akt) activity, affecting downstream signaling, reducing epithelial cell (EC) proliferation, and contributing to intestinal mucosal atrophy. We hypothesized that promoting Akt activity would prevent these changes. We used a novel Akt-activating peptide, TCL1 (a head-to-tail dimer of the Akt...
BACKGROUND The management of acute pancreatitis (AP) frequently includes parenteral nutrition, but conditionally essential amino acids such as glutamine are not included in conventional total parenteral nutrition (TPN). AIM This study was conducted to determine whether the inclusion of glutamine has a beneficial effect in patients with AP receiving TPN. METHODS In a randomized, controlled s...
Total parenteral nutrition (TPN) is commonly used clinically to sustain patients; however, TPN is associated with profound mucosal atrophy, which may adversely affect clinical outcomes. Using a mouse TPN model, removing enteral nutrition leads to decreased crypt proliferation, increased intestinal epithelial cell (IEC) apoptosis and increased mucosal tumor necrosis factor alpha (TNF-α) expressi...
The preterm intestine is immature and responds differently to total parenteral nutrition (TPN) and enteral nutrition, compared with the term intestine. We hypothesised that in preterms, diet composition and feeding route affect mucosal morphology, enterocyte mitosis and apoptosis, and the distribution of laminin-1, fibronectin and collagen IV (extracellular matrix proteins (ECMP)). Preterm pigl...
Staphylococcus aureus and Staphylococcus epidermidis possess a 42-kDa cell wall transferrin-binding protein (Tpn) which is involved in the acquisition of transferrin-bound iron. To characterize this protein further, cell wall fractions were subjected to two-dimensional sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis blotted, and the N-terminus of Tpn was sequenced. Comparison of...
BACKGROUND Total parenteral nutrition (TPN) has historically been used conservatively in the management of patients after pancreaticoduodenectomy (PD). Herein, we evaluate the indications for and outcomes associated with TPN use in a high-volume pancreatic surgery center. MATERIALS AND METHODS We retrospectively queried our institution's pancreatic surgery database for patients who received T...
total parenteral nutrition (tpn) has a vital role in controlling nutritional deficiencies especially in patients with critical conditions who are confined to bed in intensive care unit (icu). complete evaluation of the nutritional status of these patients is necessary to achieve their nutritional goal. the aim of this investigation was to study the complete blood count (cbc), coagulation parame...
We consider Time Petri Nets (TPN) for which a firing time interval is associated with each transition. State space abstractions for TPN preserving various classes of properties (LTL, CTL, CTL) can be computed, in terms of so called state classes. Some methods were proposed to check quantitative timed properties but are not suitable for effective verification of properties of real-life systems. ...
Total parenteral nutrition (TPN) is essential for patients with impaired gut function but leads to parenteral nutrition-associated liver disease (PNALD). TPN disrupts the normal enterohepatic circulation of bile acids, and we hypothesized that it would decrease intestinal expression of the newly described metabolic hormone fibroblast growth factor-19 (FGF19) and also glucagon-like peptides-1 an...
Sepsis is the most common morbidity in preterm infants, who often receive total parenteral nutrition (TPN). We hypothesized that gut barrier function is compromised in TPN-fed compared with enterally fed newborn piglets (ENT pigs). Colostrum-deprived newborn pigs were implanted with jugular venous and bladder catheters under general anesthesia. Pigs were either administered TPN (n = 15) or fed ...
