BACKGROUND Improved compliance in active ulcerative colitis (UC) is likely to improve healthcare efficiency by reducing time spent in active mild to moderate UC state. To establish whether once daily (OD) mesalazine offers economic advantages over twice daily (BD) dosing in active UC, we evaluated the outcomes and costs of a recently published randomized study. METHODS A cost-effectiveness mo...

Let G be a bridgeless connected undirected (b.c.u.) graph. The oriented diameter of G, OD(G), is given by OD(G)=min{diam(H): H is an orientation of G}, where diam(H) is the maximum length computed over the lengths of all the shortest directed paths in H . This work starts with a result stating that, for every b.c.u. graph G, its oriented diameter OD(G) and its domination number (G) are linearly...

Limited studies exist in the literature on demand related travel patterns, analysis of which requires a rich database Origin Destination (OD) matrices with appropriate clustering algorithms. This paper develops methodological framework to explore typical patterns from multi-density high dimensional and estimate OD corresponding those patterns. The contributions are multi-fold. First, cluster hi...

Relatively little is known about movements of the eyes, head, and hands in natural tasks. Normal behavior requires spatial and temporal coordination of the movements in more complex circumstances than are typically studied, and usually provides the opportunity for motor planning. Previous studies of natural tasks have indicated that the parameters of eye and head movements are set by global tas...

OBJECTIVE Proton magnetic resonance spectroscopy (1H MRS) in opiate dependence showed abnormalities in neuronal viability and glutamate concentration in the anterior cingulate cortex (ACC). Metabolite levels in dorsolateral prefrontal cortex (DLPFC) or orbitofrontal cortex (OFC) and their neuropsychological correlates have not been investigated in opiate dependence. METHODS Single-volume prot...

We previously prepared and pharmaceutically evaluated ginger orally disintegrating (OD) tablets, optimized the base formulation, and carried out a clinical trial in healthy adults in their 20 s and 50s to measure their effect on salivary substance P (SP) level and improved swallowing function. In this study, we conducted clinical trials using the ginger OD tablets in older people to clinically ...

INTRODUCTION An entirely new type of staphyloma has been recently described as dome-shaped macula (DSM). It is characterized by an abnormal convex macular contour within the concavity of a posterior staphyloma. We found DSM associated with serous macular detachment (SMD) and tilted disc in two consecutive cases. CASE REPORTS Case 1: A 37-year-old female presented to our department because of ...

BACKGROUND UV-vis spectrophotometric optical density (OD) is the most commonly-used technique for estimating chromophore formation and cell concentration in liquid culture. OD wavelength is often chosen with little thought given to its effect on the quality of the measurement. Analysis of the contributions of absorption and scattering to the measured optical density provides a basis for underst...

Background: One of the most common symptoms of COVID-19 infection is Olfactory Dysfunction (OD). Objectives: This study aims to investigate OD and phantosmia in COVID-19 cases from northern Iran. Materials & Methods: In this cross-sectional study, participants were 400 patients with COVID-19 infection in Rasht, Iran from March 2019 to September 2020. All the patients were evaluated in terms o...
