The mitochondrial‐derived peptide MOTS ‐c: a player in exceptional longevity?
2015
Mitochondrial-derived peptides (MDP) are encoded by functional short open reading frames in the mitochondrial DNA (mtDNA). These include humanin, and the recently discovered mitochondrial open reading frame of the 12S rRNA-c (MOTS-c). Although more research is needed, we suggest that the m.1382A>C polymorphism located in the MOTS-c encoding mtDNA, which is specific for the Northeast Asian population, may be among the putative biological mechanisms explaining the high longevity of Japanese people. 5.760 JCR (2015) Q1, 36/187 Cell biology, 3/49 Geriatrics & gerontology UEM
Starvation-induced expression of autophagy-related genes in Arabidopsis
2005
Background information. Autophagy is a catabolic process for degradation of cytoplasmic components in the vacuolar apparatus. A genome-wide survey recently showed evolutionary conservation among autophagy genes in yeast, mammals and plants. To elucidate the molecular and subcellular machinery responsible for the sequestration and subsequent digestion of intracellular material in plants, we utilized a combination of morphological and molecular methods (confocal laser-scanning microscopy, transmission electron microscopy and real-time PCR respectively). Results. Autophagy in Arabidopsis thaliana suspension-cultured cells was induced by carbon starvation, which triggered an immediate arrest of…
How the physical similarity of avatars can influence the learning of emotion regulation strategies in teenagers
2015
Greater emotion regulation when observing a physically similar avatar.Greater frustration induction when observing a physically similar avatar.Greater physical identification with physically similar avatar.Significant change in brain when observing a physically similar avatar. The aim of this study is to evaluate the influence of the physical similarity of avatars with the user on emotion regulation strategy training. In this study twenty-four teenagers observed an avatar (either physically similar to the participant or neutral) that gets frustrated with his/her computer, after which he/she applies an emotion regulation strategy (slow breathing). The intensity of the emotional induction and…
Arrays in rays: terminal addition in echinoderms and its correlation with gene expression
2005
Summary The echinoderms are deuterostomes that superimpose radial symmetry upon bilateral larval morphology. Consequently, they are not the first animals that come to mind when the concepts of segmentation and terminal addition are being discussed. However, it has long been recognized that echinoderms have serial elements along their radii formed in accordance with the ocular plate rule (OPR). The OPR is a special case of terminal growth, forming elements of the ambulacra that define the rays in echinoderms. New elements are added at the terminus of the ray, which may or may not be marked by a calcified element called the terminal plate (the “ocular” of sea urchins). The OPR operates in eve…
In light of the ends. Copyright hysteresis and private copy exception after the British Academy of Songwriters, Composers and Authors (BASCA) and oth…
2015
In British Academy of Songwriters, Composers and Authors (BASCA) and others v Secretary of State for Business, Innovation and Skills, the High Court of Justice in matter of private copy exception provides the twofold prime opportunity to shed light on the state of the art of copyright in the UK and to flesh out the idea of 'legal hysteresis’. I support the reintroduction of the private copy exception, possibly in a less narrow fashion, and I explain the reasons why I am confident that my expectations will be fulfilled.
Skolebygg : påvirkes elevens prestasjoner av skolebyggets utforming?
2011
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2011 Denne oppgaven tar sikte på å estimere hvordan ulike typer skolebygg påvirker elevers læringsutbytte. Utgangspunktet for arbeidet er problemstillingen: ”Hva er effekten av ulike typer skolebygg? Påvirker utformingen av læringsarenaen elevenes prestasjoner?” For å besvare denne problemstillingen velges en kvantitativ tilnærming. Ulike skoletyper som tradisjonelle klasseromsskoler og fleksible baseskoler blir identifisert gjennom et spørreskjema som sendes ut til de utvalgte skolene. Elevers læringsutbytte måles ved et karaktergjennomsnitt som inkluderer alle avsluttende karakterer på ungdomstrinnet, grunnskolepoeng. I ana…
Analyse av fremdrift med tilhørende avvik ved Prosjekt Lyngdal Ungdomsskole : en casestudie
2013
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2013 Kostnadsoverskridelser og forsinkelser er noe vi f ar stadig inntrykk av at intre er i store byggeprosjekter. Denne masteroppgaven undersø kte et pågående prosjekt og registrerte og analyserte alle avvik i forhold til fremdriften. Det ble ogs å undersø kt hvilke metoder som ble brukt for fremdriftstyring, og hvordan dette fungerte i praksis. Planlagt ferdigstillelse av Prosjekt Lyngdal Ungdomsskole var 01/05/2013, men revidert plan indikerer en overtakelse 31/05/2013. Det er fortsatt usikkert om bygget og uteomr ådet vil væ re komplett ferdigstilt til skolestart 2013, som var overordnet m ål. Det ble totalt funnet 150 av…
Etterspørselen etter leie av næringslokaler i Kristiansand : status i dag, videre utvikling og ulikheter i forskjellige områder av byen
2009
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2009 Hensikten med denne oppgaven er å kartlegge hvordan etterspørselen etter leie av næringseiendom er i Kristiansand. Jeg har samlet inn store mengder data om temaet, og datamaterialet brukes for å teste om det er mulig å fastslå noen sammenheng mellom tidligere utarbeidede teorier og mine data. Teoriene jeg har benyttet i oppgaven er DiPasquale & Wheatons (1996) modell for analyse av utleiemarkedet for næringseiendom og Rosens (1974) hedonistiske leiepristeori. I oppgaven har jeg utformet to hypoteser. Den første hypotesen sier at en bedrifts ønskede areal avhenger av antall ansatte. Forhåndsantakelsen til denne påstanden …
Resistance to the Bacillus thuringiensis bioinsecticide in a field population of Plutella xylostella is due to a change in a midgut membrane receptor.
1991
The biochemical mechanism for resistance to Bacillus thuringiensis crystal proteins was studied in a field population of diamondback moths (Plutella xylostella) with a reduced susceptibility to the bioinsecticidal spray. The toxicity and binding characteristics of three crystal proteins [CryIA(b), CryIB, and CryIC] were compared between the field population and a laboratory strain. The field population proved resistant (greater than 200-fold compared with the laboratory strain) to CryIA(b), one of the crystal proteins in the insecticidal formulation. Binding studies showed that the two strains differ in a membrane receptor that recognizes CryIA(b). This crystal protein did not bind to the b…
Top-down effects of a lytic bacteriophage and protozoa on bacteria in aqueous and biofilm phases
2014
Lytic bacteriophages and protozoan predators are the major causes of bacterial mortality in natural microbial communities, which also makes them potential candidates for biological control of bacterial pathogens. However, little is known about the relative impact of bacteriophages and protozoa on the dynamics of bacterial biomass in aqueous and biofilm phases. Here, we studied the temporal and spatial dynamics of bacterial biomass in a microcosm experiment where opportunistic pathogenic bacteria Serratia marcescens was exposed to particle‐feeding ciliates, surface‐feeding amoebas, and lytic bacteriophages for 8 weeks, ca. 1300 generations. We found that ciliates were the most efficient enem…
