this study was undertaken to define the prevalence of the upper gastrointestinal (gi) lesions, dyspeptic symptoms, h.pylori infection, and the impact of duration of dialysis on upper gi symptoms and lesions of children with end-stage renal disease. we studied 69 children with esrd who were under regular hemodialysis therapy in our department. the age of the patients were between 4-18 years (mea...

This paper outlines the methodology to add glycaemic index (GI) and glycaemic load (GL) functionality to food DietPLUS, a Microsoft Excel-based Malaysian food composition database and diet intake calculator. Locally determined GI values and published international GI databases were used as the source of GI values. Previously published methodology for GI value assignment was modified to add GI a...

The alpha subunits of the stimulatory and inhibitory G proteins, Gs alpha and Gi alpha, activate transmembrane-signaling systems involved in the control of cell proliferation. We have investigated the pattern of expression of Gi alpha subtypes and Gi alpha-mediated proliferative responses in the human thyroid. Human thyroid membranes contain two subtypes of Gi alpha, Gi alpha-1 and Gi alpha-2, ...

BACKGROUND Gastrointestinal (GI) complaints are common in shift workers. This study examines the relationship between work schedules and GI symptoms, medications, and diagnoses. METHODS In a cross-sectional survey of 343 US auto factory workers, four work schedule variables were examined: assigned shift, number of hours worked, number of night hours, and schedule variability. Multiple regress...

Gastrointestinal (GI) hemangiomas are relatively rare benign vascular tumors. The choice of an appropriate diagnostic method depends on patient age, anatomic location, and presenting symptoms. However, GI hemangiomas are not a common suspected cause of GI bleeding in children because of their rarity. Based on medical history, laboratory results, and imaging study findings, the patient could be ...

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.

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...
