Morphology of experimentally denervated and reinnervated rat facial muscle I. Histochemical and histological findings

1994

The morphological changes in rat facial muscles were evaluated after permanent denervation and were compared with findings after immediate reinnervation. Thirty rats underwent transection of the left and right facial nerves immediately followed by hypoglossal-facial nerve anastomosis on the right side (muscular reinnervation) and removal of 8-10 mm of the facial plexus on the left side (permanent muscular denervation). Levator labii muscle samples of both sides were collected sequentially at 2, 6, 7, 10, 20, and 24 weeks after surgery and submitted to routine histological and enzyme histochemical staining procedures. In normal levator labii muscles a typical "chessboard" pattern was found, …

Aktiv implementering av operasjonelle Lean prinsipper blant prosjektdeltakere på byggeplass : En kvalitativ casestudie

2019

Masteroppgave industriell økonomi og teknologiledelse IND590 - Universitetet i Agder 2019 Methods such as Lean and continuous improvement characterize an increasing number ofcompanies across industries. Despite a willingness to improve, studies show that companiesare struggling getting the methodology to last after pilot projects and hence fall back intoold routines. The solution seems to be an increased involvement of employees and a changein the management’s focus to promote employee independence. Micromanagement mustbe replaced with a management that focuses on processes rather than results, believingin employees capabilities. When introducing a principle- based managament it enables the…

Eksperttankegang gjennom en hel verdikjede : En studie av Best Value Procurement kontrahering og hvordan tankegangen videreføres oppstrøms i verdikje…

2020

Master's thesis in Industrial economics and technology management (IND590) According to the Rådgivende Ingeniør Forening (RIF), there is a need for changes in project execution by way of early involvement of subcontractors and focus on their expertise. Nye Veier AS wants to be involved in making these changes and therefore have adopted the Best Value Procurement methodology. This contracting method is intended to ensure that projects are awarded to the best expert, that is most suitable to complete the project. The construction industry has long been criticized for inefficiency and for its high frequency of conflicts during the execution phase of projects. Traditionally, price has been the …

Coping with pandemics using social network sites: A psychological detachment perspective to COVID-19 stressors

2022

Prior research has often portrayed information technology (IT) as a stressor. In this paper, we propose and demonstrate that IT can also be an effective means of coping with life stressors, including those induced by pandemics such as COVID-19. We thus deviate from the common IT-as-a-stressor perspective and adopt an IT-as-a-coping-mechanism viewpoint. To this end, we apply the stressor-detachment model from organisational psychology to the use of social network sites (SNSs) in coping with stressors wrought by the COVID-19 pandemic. We examine psychological well-being as our dependant variable and introduce psychological detachment through SNS use as a mediator and moderator of the associat…

Affinity scale between a carrier and a drug in DPI studied by atomic force microscopy.

2002

The dry powder inhalers (DPIs) consist, in the most cases, of ordered mixture where the particles adhesion results of interactions between the drug and the carrier. Generally, one step of production process is the micronization of the drug particles in order to reduce the size for ordered mixing optimization. But this operation is known to partially create an amorphous surface. In this case, surrounding storage conditions, like relative humidity (RH), are able to modify the percentage of amorphous drug surface. The aim of this study was to investigate surface reactivity, surface energy and direct force measurements by atomic force microscopy (AFM) between lactose (carrier) and zanamivir (dr…

Ant crickets and their secrets: Myrmecophilus acervorum is not always parthenogenetic (Insecta: Orthoptera: Myrmecophilidae)

2021

Abstract Previously considered as a thelytokous parthenogenetic species, the widespread ant cricket Myrmecophilus acervorum actually turns out to have a mixed reproductive system: our recent surveys in the central part of its distribution area has revealed the presence of both sexes. Detailed morphological and morphometric descriptions of the previously unknown males are here provided. New data on species distribution in south-eastern Europe are presented, including the first records of M. balcanicus in Bulgaria and of M. nonveilleri in Bulgaria and Hungary. Phylogenetic and phylogeographic analyses have revealed several haplotypes of M. acervorum in Europe, with six of them forming a parth…

Depletion of alphaV integrins from osteosarcoma cells by intracellular antibody expression induces bone differentiation marker genes and suppresses g…

1999

Integrin heterodimers sharing the common alphaV subunit are receptors for adhesion glycoproteins such as vitronectin and fibronectin. They are suggested to play an essential role in cell anchoring, differentiation, and survival. Here, we describe the construction of an expression plasmid coding for an intracellular single-chain antibody against alphaV integrin subunit. Saos-2 osteosarcoma cells transfected with this DNA construct showed an approximately 70-100% decrease in the cell surface expression of alphaVbeta3 and alphaVbeta5 integrins as shown by flow cytometry. Intracellular antibody expression had no effect on the mRNA levels of alphaV integrin. Pulse chase experiments of metabolica…

Global health security and islands as seen through COVID-19 and vaccination

2022

Since the declaration of COVID-19 as a pandemic in March 2020, significant research and attention has focused on countries’ abilities and interests in enacting response measures to the spread of the coronavirus including lockdowns, travel restrictions, and vaccination programmes to contain infections, hospitalisations, and deaths. As the pandemic has continued, much discussion has also centred on the ability of islands to control borders, enact public health measures, and keep the virus out or controlled, owing in part to presumed islandness characteristics of isolation and remoteness. Drawing from ongoing empirical examples of island experiences in the context of COVID-19, this article exa…
