in this paper, a formal model for antivirus update agent system is presented based on mobile agent technology and predicate/transition petri nets. the mobile agent system contains two mobile agents called dca and una. it sends out agents to update antivirus on client computers in a network. each agent takes on a specified responsibility. first, dca roams through the network and check the last d...

Plant phenology models, especially leafing models, play critical roles in evaluating the impact of climate change on the primary production of temperate plants. Existing models based on temperature alone could not accurately simulate plant leafing in arid and semi-arid regions. The objective of the present study was to test the suitability of the existing temperature-based leafing models in ari...

Penelitian mencoba untuk menentukan konsentrasi ekstrak akar tuba yang efektif meracuni patin (Pangasius pangasius) dan hubungan antara waktu pingsan pulih berdasarkan racun tuba. Indikatornya didasarkan atas tercepat terlama. Sebanyak 72 berukuran panjang total 13-37,5 cm dijadikan sebagai sampel penelitian. Konsentrasi minimal ditentukan 10 ppm, menengah 45 maksimal 80 ppm. < ppm tidak mem...

Total parenteral nutrition (TPN) results in a number of derangements to the intestinal epithelium, including a loss of epithelial barrier function (EBF). As TPN supplemented with glutamine has been thought to prevent this loss, this article further defined the impact of glutamine on EBF, and investigated potential mechanisms that contributed to the preservation of EBF. C57BL/6J male mice were r...

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...

Nutrition support for patients in hospital has become an essential form of therapy. Total parenteral nutrition (TPN) was the preferred way of giving nutrition to hospital patients for many years but enteral nutrition (EN) is now the preferred route. EN is believed to promote gut function and prevent translocation of intestinal bacteria, thus reducing the incidence of sepsis in critically ill pa...

The ER protein tapasin (Tpn) forms a bridge between MHC class I H chain (HC)/beta(2)-microglobulin and the TAP peptide transporter. The function of this TAP-associated complex was unclear because it was reported that soluble Tpn that has lost TAP interaction would be fully competent in terms of peptide loading and Ag presentation. We found, however, that only wild-type human Tpn (hTpn), but not...

Multistage interconnection networks (Banyan networks) are frequently used for performance evaluation of communication systems (e.g. Ethernet and ATM switches). There exist several studies (see [9] and [7]) describing the performance of networks in which packets (or frames) are unicasted (i.e. one switching element (SE) sends the packet to one and only one other SE). A model for MINs in case of ...

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...
