gastrointestinal (gi) bleeding in pediatric patients has several causes. vascular malformation of the small bowel is a rare disease leading to pediatric gi bleeding. to our knowledge, few reports describe ultrasound and computed tomography findings of venous malformations involving the small bowel. we present a case of long-segmental and circumferential vascular malformation that led to gi blee...

This paper addresses the problem of finding a class of representative itemsets up to subitemset isomorphism. An efficient algorithm is of practical importance in the domain of optimal sorting networks. Although only exponential algorithms for solving the problem exist in the literature, the complexity classification of the problem has never been addressed. In this paper, we present a complexity...

Enterprises compete in high dynamic and fast changing markets. Reacting quickly and flexibly to market changes is a crucial competitive advantage for an enterprise. Therefor premises of strategic planning and achievement of strategic goals have to be controlled permanently and in a systematic way. Strategic control which is part of strategic management monitors premises of the corporate strateg...

Background: Gastrointestinal (GI) malignancies are the most common cancers and account for nearly half of all cancer-related deaths in Iran. There was a strong association between human papillomavirus (HPV) infection and urogenital cancers, in particular the cervix. However, there is no clear causal relationship in all types of cancers, including gastrointestinal cancers. Therefore, the present...

G12/13 or Gq signaling pathways activate platelet GPIIb/IIIa when combined with Gi signaling. We tested whether combined Gi and Gz pathways also cause GPIIb/IIIa activation and compared the signaling requirements of these events. Platelet aggregation occurred by combined stimulation of Gi and Gz pathways in human platelets and in P2Y1-deficient and G qdeficient mouse platelets, confirming that ...

BACKGROUND/AIMS While chemoradiotherapy (CRT) is considered to be a reasonable treatment for locally advanced pancreatic cancer (LAPC), there is little information about the associated risk of gastrointestinal (GI) hemorrhage. We investigated the clinical features of GI toxicity after CRT in patients with LAPC and examined the effect of GI hemorrhage on survival. METHODS Patients enrolled in ...

OBJECTIVE Chronic granulomatous disease (CGD) is a rare disorder of phagocyte oxidative metabolism. In addition to infectious complications, granulomatous lesions often involve hollow viscera, especially the gastrointestinal (GI) tract. The objective of this study was to evaluate the clinical presentation, prevalence, and consequences of GI involvement in patients with CGD. METHODS The medica...

The aim of this study was to investigate the effect of Cystamine (CYS) on the hippocampal CA1 region in rats with whole cerebral ischemia. A total of 104 adult male Sprague-Dawley rats were prepared using the modified Pulsinelli method for a global Cerebral Ischemia (GI) model, and then randomly divided into a sham group (S, n=8), a GI group (GI, n=48), and a GI+CYS group (GI+CYS, n=48). The la...

The metabolic and performance benefits of prior consumption of low-glycaemic index (GI) meals v. high-GI meals were determined in extended high-intensity intermittent exercise. Participants (ten males and four females, aged 25·8 (sd 7·3) years) completed two testing days (each consisting of back-to-back 90-min intermittent high-intensity treadmill running protocols separated by 3 h) spaced by a...
