Both oxidative damage and inflammation are elevated in brain from neurodegenerative patients [1], but their pathogenic significance remains unclear. Central nervous system has its own resident immune system, in which glial cells not only serve such as supportive and nutritive roles for neuron cells, also engage in several inflammatory processes that defend the central nervous system from pathogens and help it to recover from stres…
CNS involvement in OFD1 syndrome: a clinical, molecular, and neuroimaging study
2014
Background Oral-facial-digital type 1 syndrome (OFD1; OMIM 311200) belongs to the expanding group of disorders ascribed to ciliary dysfunction. With the aim of contributing to the understanding of the role of primary cilia in the central nervous system (CNS), we performed a thorough characterization of CNS involvement observed in this disorder. Methods A cohort of 117 molecularly diagnosed OFD type I patients was screened for the presence of neurological symptoms and/or cognitive/behavioral abnormalities on the basis of the available information supplied by the collaborating clinicians. Seventy-one cases showing CNS involvement were further investigated through neuroimaging studies and neur…

Exploring hospital certification processes from the certification body’s perspective – a qualitative study
2020
Abstract Background Hospital certification is an external assessment mechanism to assure quality and safety systems. Auditors representing the certification body play a key role in certification processes, as they perform the assessment activities and interact with the involved healthcare organizations. There is limited knowledge about the approaches and methods that auditors use, such as role repertoire, conduct, and assessment practice. The purpose of this study was to explore auditors’ practice in hospital certification processes, guided by the following research questions: What styles do auditors apply in hospital certification processes, and how do auditors perceive their role in hospi…
Endringskapasitet – en nøkkel for å lykkes med gevinstrealisering i spesialisthelsetjenesten? : En studie av hvordan mellomledere opplever at endring…

Masteroppgave i helse- og sosialinformatikk HSI500 - Universitetet i Agder 2018 Background: If an organisation is to reap the potential benefits of new technology, it must modify its work processes. However, the specialist health service appears to be experiencing significant challenges because it is constantly under pressure to change and improve its efficiency. This can weaken its capacity for change and, at worst, lead to long-term reductions in productivity and efficiency. Purpose: The purpose of this study is to examine how middle managers in the specialist health service feel they can influence developments in change capacity. The aim is to contribute to an awareness of the importance…
Liquid Biopsy in Cancer Patients: The Hand Lens to Investigate Tumor Evolution
2017
In recent years the treatment of cancer patients has profoundly changed due to a better comprehension of the biological processes underlying tumor development and progression. Several tumors are defined as “oncogene addicted” and this discovery has led the way to the development of target therapies that are able to specifically kill cancer cells sparing normal cells from toxicity. Nowadays treatment decision is strictly dependent on the molecular characterization of the tumor; thus the path of cancer patients’ survival is tissue dependent but this may have several limitations. Indeed a single tissue biopsy represents only a snapshot limited in time and space but we are learning that tumor e…
Hierarchical Mass Transfer Analysis of Drug Particle Dissolution, Highlighting the Hydrodynamics, pH, Particle Size, and Buffer Effects for the Disso…
2020
Dissolution is a crucial process for the oral delivery of drug products. Before being absorbed through epithelial cell membranes to reach the systemic circulation, drugs must first dissolve in the human gastrointestinal (GI) tract. In vivo and in vitro dissolutions are complex because of their dependency upon the drug physicochemical properties, drug product, and GI physiological properties. However, an understanding of this process is critical for the development of robust drug products. To enhance our understanding of in vivo and in vitro dissolutions, a hierarchical mass transfer (HMT) model was developed that considers the drug properties, GI fluid properties, and fluid hydrodynamics. T…
2-[(1-Methyl-1H-pyrrol-2-yl)carbonyl-meth-yl]isoindoline-1,3-dione.
2009
The asymmetric unit of the title compound, C15H12N2O3, contains two almost identical molecules forming an nearly C2-symmetric dimeric pattern. The dihedral angles between the pyrrole ring and the phthalimide unit are 82.95 (8) and 86.57 (8)° for the two molecules. Within such a dimer, the phthalimide units of the two molecules form a dihedral angle of 1.5 (5)°.
6-Amino-1-benzyl-4-(4-chloro-phen-yl)-3-(4-pyrid-yl)-1,4-dihydro-pyrano[2,3-c]pyrazole-5-carbonitrile.
2008
The crystal structure of the title compound, C25H18ClN5O, was determined in the course of our studies on the synthesis of 1,4-dihydropyrano[2,3-c]pyrazole as an inhibitor of the p38 mitogen-activated protein kinase (MAPK). The compound was prepared via a base-catalysed synthesis from 1-benzyl-3-(4-pyridyl)-1H-pyrazol-5(4H)-one with p-chloroaldehyde and malononitrile. The crystal data obtained were used to generate a three-dimensional pharmacophore model for in silico database screening. The phenyl ring is disordered over two positions, with site occupancy factors of 0.55 and 0.45. The dihedral angles between the 1,4-dihydropyrano[2,3-c]pyrazole unit and the chlorophenyl and pyridine rings a…
A triclinic polymorph of (−)-(S)-N-benzyl-2-[(R)-6-fluorochroman-2-yl]-2-hydroxyethanaminium bromide
2013
The title salt, C18H21FNO2+·Br−, determined at 115 K, crystallizes in the triclinic space groupP1. The previously reported polymorph occurs in the monoclinic space groupP21and has two independent molecules in the asymmetric unit [Peeterset al.(1993).Acta Cryst.C49, 2157–2160]. In the title molecule, the pyran rings adopt half-chair conformations. The absolute configuration isSfor the hydroxy-bearing C atom andRfor the asymmetric C atom in the dihydropyran unit. In the crystal, the components are linked by N—H...Br and O—H...Br hydrogen bonds, forming chains along thec-axis direction. The crystal studied was refined as an inversion twin.
