Objective: Upper gastrointestinal bleeding (UGB) is one of the most important and serious cause of emergency admission in childhood. The aim of the study was to evaluate the etiological factors and the treatment approaches in patients with UGB.Methods: In this retrospective study, children with UGB admitted to emergency clinics of Istanbul Health Sciences University Kanuni Sultan Suleyman...

The generalized deBruijn digraphGB(n,m) is the digraph (V ,A)where V = {0, 1, . . . ,m−1} and (i , j ) ∈ A if and only if j ≡ in + α (mod m) for some α ∈ {0, 1, 2, . . . ,n − 1}. By replacing each arc of GB(n,m) with an undirected edge and eliminating loops and multi-edges, we obtain the generalized undirected de Bruijn graph UGB(n,m). In this article, we prove that when 2n2 ≤ m ≤ n3 the diamet...

Reasonable delineation of the urban growth boundary (UGB) plays a vital role in guiding orderly space and ensuring environmental health. Existing methodologies for UGB have failed to address significance ecological security. Therefore, this study presents framework that couples security pattern (ESP) establishment construction land expansion (CLE) simulation delineate UGB. The proposed is appli...

OBJECTIVE To assess the accuracy of the determination of Helicobacter pylori infection by a stool immunoassay in patients with upper-gastrointestinal bleeding (UGB) of peptic origin, in comparison with the routine histological study, serology, rapid urease and 13C-breath tests. METHODS Sixty-eight patients with endoscopically proven UGB of peptic origin were included. The presence of H. pylor...

In the literature, Improved Recycling Folded Cascode (IRFC) Operational Transconductance Amplifier (OTA) is proposed for enhancing the DC gain and the Unity Gain Bandwidth (UGB) of the Recycling Folded Cascode (RFC) OTA. In this paper, an enhanced IRFC (EIRFC) OTA which uses positive feedback at the cascode node is proposed for enhancing the differential mode (DM) gain without changing the unit...
