ions. The OMG has published guidelines for designing object services and their interfaces [OMG97]. The service approach has also been adopted in the Distributed Object-Oriented Reliable Service (DOORS) [CHY+98], currently in development at Bell Labs. Our work on CORBA fault-tolerant services has signi cantly in uenced many of the proposals that have recently been made to the OMG in the context ...

statement of problem: the extraction versus non-extraction debate is almost as old as the advent of orthodontic practice and up to now, this dilemma remains. recently, the american board of orthodontics (abo) has developed a method by the name of objective grading system (ogs) in order to evaluate the results of orthodontic treatment. aim: the aim of the present study was to evaluate and compar...

BACKGROUND To date, no specific therapy is available for optic glioma (OG)-induced visual loss. OBJECTIVE To evaluate the effects on visual function of murine nerve growth factor (NGF) eye drop administration in children with severe visual impairment due to low-grade OGs. METHODS Five patients with OGs and advanced optic nerve atrophy were assessed before and after a single 10-day course of...

OBJECTIVE To test the hypothesis that variability among posttreatment Angle Class I, nonextraction patients is not related to patient and treatment factors. MATERIALS AND METHODS One hundred thirty-eight subjects were randomly selected from the archives of the Department of Orthodontics, St Louis University. Patient factors evaluated included age, sex, mandibular plane angle, and ANB angle; t...

BACKGROUND Gait disorders are very common in children with spastic diplegia cerebral palsy (CP). In order to improve the CP children's gait and to quantify the outcomes of this intervention it becomes essential to perform an instrumented analysis before and after the intervention. OBJECTIVES To analyze the correlation among the Edinburgh Visual Gait Scale (EVGS), the Visual Gait Assessment Sc...

Overlapping genes (OGs) represent one type of widespread genomic feature in bacterial genomes and have been used as rare genomic markers in phylogeny inference of closely related bacterial species. However, the inference may experience a decrease in performance for phylogenomic analysis of too closely or too distantly related genomes. Another drawback of OGs as phylogenetic markers is that they...

INTRODUCTION Oligodendrogliomas (OGs) account for <20% of all intracranial tumors and 25% of gliomas. Despite improvements in imaging techniques allowing for earlier diagnosis, OG is rare among the pediatric population. This study examines a large cohort of OG patients in an effort to define the demographic, clinical, and pathologic factors associated with clinical and survival outcomes. METH...

With the inclusion of new members, understanding about evolutionary mechanisms and processes by which members of the proposed order, Megavirales, have evolved has become a key area of interest. The central role of gene acquisition has been shown in previous studies. However, the major drawback in gene acquisition studies is the focus on few MV families or putative families with large variation ...

Plants have substantially higher gene duplication rates compared with most other eukaryotes. These plant gene duplicates are mostly derived from whole genome and/or tandem duplications. Earlier studies have shown that a large number of duplicate genes are retained over a long evolutionary time, and there is a clear functional bias in retention. However, the influence of duplication mechanism, p...

alpha-1,4-linked oligogalacturonides (OGs) are pectic fragments of plant cell walls that are able to induce defence and developmental responses. To understand plant responses to OGs at the transcriptional level, changes in gene expression were examined using oligonucleotide-based microarrays that cover almost the entire Arabidopsis transcriptome. In suspension-cultured Arabidopsis thaliana (L.)...
