Popular Abstract in Swedish Alla levande organismer måste kunna anpassa sig till förändringar i sin omgivning, såsom kyla, värme eller torka. Vid sådana förändringar tar enskilda celler emot signaler ifrån sin omgivning via särskilda s.k. receptorproteiner på cellytan. Receptorproteinerna skickar signalerna vidare in i cellen, där de kan ge upphov till en kedja av processer, vilka slutligen leder Phosphoinositides (PIs) play major roles in cell signal transduction. Although it is clear that PIs are important components also in plant signalling, little is known about their roles in plant cells, compared to animal cells. This thesis describes work on two PI-dependent enzymes involved in plant intracellular signalling, phosphoinositide-specific phospholipase C (PI-PLC) and 3-phosphoinositide

The monotone rearrrangement algorithm was introduced by Hardy, Littlewood and Po ́lya as a sorting device for functions. As- suming that x is a monotone function and that an estimate xn of x is given, consider the monotone rearrangement xˆn of xn. This new estimator is shown to be uniformly consistent. Under suitable as- sumptions, pointwise limit distribution results for xˆn are obtained. The fra

This paper explores the linguistic encoding of placement and removal events in Jahai (Austroasiatic, Malay Peninsula) on the basis of descriptions from a video elicitation task. It outlines the structural characteristics of the descriptions and isolates semantically a set of situation types that find expression in lexical opposites: (1) putting/taking, (2) inserting/extracting, (3) dressing/undres

Popular Abstract in Swedish Att balansera. Cancer från ett primärvårdsperspektiv. Diagnostik, posttraumatisk stress och vård vid livets slut Denna avhandling belyser cancer från en utgångspunkt som kanske inte handlar om vad man först kommer att tänka på när man hör ordet cancerforskning. Det handlar inte om att “lösa cancerns gåta” eller att hitta nya metoder för behandling eller diagnos. UtgångThis thesis explores cancer from a primary care perspective covering three areas: diagnosis, posttraumatic stress disorder (PTSD), and end-of-life care. We analyzed patient records of every child diagnosed with a malignancy in a defined area. During 12 years 68 children were diagnosed (incidence 14/100,000). For 68% the diagnosis was initiated in primary care. There were 25 children with leukemia

Sammanfattning av projektets resultatInom projektet har vi studerat effekter av ekonomiska styrmedel för att nå en mer hållbar konsumtion från ett miljö- och hälsoperspektiv. Mer specifikt har vi studerat hur konsumenter ändrar sitt konsumtionsbeteende till följd av att vi ger dem information eller inför skatter och subventioner på olika varor. Vi har även studerat i vilken utsträckning konsumente

Popular Abstract in Swedish Bakgrund. Det enteriska nervsystemet (ENS) — mag-tarmkanalens eget nervsystem betraktades tidigare i stor utsträckning enbart som en passiv omkopplingscentral inom det parasympatiska nervsystemet. Forskningsresultat från det senaste decenniet har emellertid gett oss ett helt nytt synsätt. ENS ― ibland refererat till som ‘The second brain’ ― uppvisar trots tillhörighet tThe thesis deals with plasticity in terms of neurotransmitter expression and survival of neurons in the adult enteric nervous system (ENS). Several motility disorders have been suggested to originate in developmental defects, neurodegeneration, or insufficient innervation by the ENS. Normal distribution of the interstitial cells of Cajal (ICC), found in close relationship to enteric neurons, is al

Popular Abstract in English Blood, a deep red fluid, circulates in vessels throughout our body. It consists of two main components, a liquid part and a cell part. The liquid portion, which is also called ‘plasma’, takes a main function in transporting water, nutrients, and immune substances. The cell components, which are suspended in the plasma, consist of three main cell types including plateletBlood transfusion is a common medical procedure when oxygen supply in the body is impaired. However, blood transfusion is not always without risks. The uncontrolled spreading of blood borne pathogens such as HIV or hepatitis B and C virus has urged researchers to look for “blood substitutes”. Many research groups have put their focuses on hemoglobin-based products (HBOCs). The major source of haem

The notion of development blocks suggests the co-evolution of technologie and industries through complementarities and the overcoming of imbalances. This paper studies groups of closely related industries and their co-evolution in the network of Swedish product innovations, by combining statistical methods and qualitative data from a newly constructed innovation output database, SWINNO. The study
