In this paper, a complete review of published researches about hierarchical facility location and hub network problems is presented. Hierarchical network is a system where facilities with different service levels interact in a top-down way or vice versa. In Hierarchical systems, service levels are composed of different facilities. Published papers from (1970) to (2015) have been studied and a c...

Malakoplakia is a rare disease with undefined etiology that has been almost exclusively reported in urology and pathology journals. We are presenting a case of colonic malakoplakia in an I8-year old young man who was referred to us with a four-year history of intermittent rectorrhagia. The pathological examination of the endoscopically resected specimen revealed pathognomonic features of ma...

Nano science and nanotechnology have revolutionized all aspects in the endodontic field. The aim of the present study was to describe the application of nanotechnology in endodontics by reviewing the literature.The application of nanomaterials, with a smaller size, for surface modification has reduced the incidence of failure in the rotary nickel-titanium files. Nanoparticles with the ability o...

AbstractGlaucoma management in pregnant patients is a real challenge, especially when the glaucoma is not controlled with medications. We report the results of 6 incisional glaucoma surgeries for the management of medically uncontrolled glaucoma patients during pregnancy. This retrospective, case series was conducted on the 6 eyes of 3pregnant patients with uncontrolled glaucoma using maximum t...

This paper reviews the current literature examining the pervasive symptom of fatigue experienced in three of the most common degenerative neurological conditions: multiple sclerosis (MS), Parkinson’s disease (PD) and post-polio syndrome (PPS). The existing literature can be considered under four headings definition and prevalence, type, cause, impact of fatigue. Fatigue is a common symptom in d...

Melanotic neuroectodermal tumour of infancy is an extremely rare neoplasm arising in newborns and young children, typically involving the face or cranium. A case arising from the maxilla, requiring extensive resection with a near-total maxillectomy, is presented. A thorough review of the literature on this unusual tumour is provided, with emphasis on prognostic factors and appropriate treatment.

Our own experience and a thorough literature review suggest that interferon α (IFNα) should be reconsidered for the treatment of acute myeloid leukemia patients. Most likely, the success of such treatment depends on the achievement of high serum levels of IFNα for several months, which can be obtained by using pegylated IFNα.

An increase in the frequency of blood donation among the donor population is liable to result in excessive iron loss and development of iron deficiency anemia. In the majority of blood banks, hemoglobin and/or hematocrit measurements are used as screening tests for the ability to donate blood even though iron stores may be depleted in donors with hemoglobin values above the arbitrarily defi...

Data Virtualization (DV) has become an important method to store and handle data cost-efficiently. However, it is unclear what kind of data and when data should be virtualized or not. We applied a design science approach in the first stage to get a state of the art of DV regarding data integration and to present a concept matrix. We extend the knowledge base with a systematic literature review ...
