OBJECTIVE The effect of preoperative total parenteral nutrition (TPN) on the rate of early (within 30 days) postoperative complications in patients with moderate to severe Crohn's disease (CD) was examined. MATERIAL AND METHODS A series of 15 consecutive patients with CD (mean CD activity index score, 270) given preoperative TPN for 18-90 days (mean, 46 days) and undergoing bowel resection an...

INTRODUCTION The purpose of this study is to determine if administration of total parenteral nutrition (TPN) immediately following radical cystectomy and urinary diversion provides significant recovery benefit when compared to patients who did not receive TPN. METHODS Retrospective chart review was performed on patients who underwent open radical cystectomy and urinary diversion from February...

The literature shows that the monoterpenes are great candidates for the development of new drugs for the treatment of various pathological processes, including painful conditions. The gamma terpinene (γ-TPN) is a monoterpene present in plant species that have multiple pharmacological properties and has structural similarity to antinociceptive monoterpenes, such as limonene and alpha-phellandren...

To evaluate the latent risk of acidosis in commercially available total parenteral nutrition (TPN) products, three types of commercially available TPN products were compared in postoperative patients. Sixty-four hospitalized patients with gastro-intestinal disease who undertook curative gastro intestinal resection were studied prospectively and administered with TPN solutions. Three types of co...

BACKGROUND To identify the microorganisms that can grow rapidly in total parenteral nutrition (TPN) solutions, we investigated the growth of the major causes of catheter-related blood stream infection (Staphylococcus aureus, Serratia marcescens, Bacillus cereus, and Candida albicans) in TPN solutions without lipid. METHODS Experiment 1: A commercial TPN solution without lipid containing multi...

Total parenteral nutrition (TPN) is an artificial way to support daily nutritional requirements by bypassing the digestive system, but long-term TPN administration may cause severe liver dysfunction. Glycyrrhizin is an active component of licorice root that has been widely used to treat chronic hepatitis. The aim of this study is to investigate the hepatoprotective effect of glycyrrhizin on TPN...

In this paper the real time operation of an automatic teller machine (ATM) is analyzed using aTimed Petri Net (TPN) model. In the modeling, the probability of arrivals, the speed andattentiveness of customers (clients) are taken to account. Different parameters are based onthe statistical data. The model is simulated for 24 hours. The diagrams of number ofsucceeded customers, failed references ...

The photochemical reduction of triphosphopyridine nucleotide by isolated chloroplasts has been known since 1951 (see “Discussion”). The discovery of this photochemical reaction marked a significant advance in the biochemical analysis of the energy conversion process of photosynthesis because it established the first link between photon capture by chloroplast pigments and the reduction of a phys...

BACKGROUND In clinical settings, early total enteral nutrition (TEN) is known to reduce the postoperative complication and infection rate as well as duration of postoperative stay compared with total parenteral nutrition (TPN) in a variety of critical conditions. We aimed to compare effects TEN and TPN on wound healing and explore its possible mechanisms using rat model. METHODS Seven days af...

In this paper we consider the model of Time Petri Nets (TPN) “à la Merlin” where a time interval is associated with the firing of a transition, but we extend it with open intervals. We also consider Timed Automata (TA) as defined by Alur & Dill. We investigate some questions related to expressiveness for these models : we study the impact of slight variations of semantics for TPN and we compare...
