Background: Ghrelin derives from endocrine cells (A-like cells) in the stomach (mainly the oxyntic mucosa). Its concentration in the circulation increases during fasting and decreases upon re-feeding. This has fostered the notion that the absence of food in the upper gastrointestinal (GI) tract stimulates the secretion of ghrelin. The purpose of the present study was to determine the concentration

BACKGROUND CONTEXT: Several studies report a favorable short-term outcome after nonoperatively treated two-column thoracic or lumbar burst fractures in patients without neurological deficits. Few reports have described the long-term clinical and radiological outcome after these fractures, and none have, to our knowledge, specifically evaluated the long-term outcome of the discs adjacent to the fra

Popular Abstract in Swedish År 2011 är det exakt 20 år sedan lärarkåren kommunaliserades. Reformen ger fortfarande upphov till diskussioner, inte minst från liberalt håll diskuteras idag lärarprofessionens status och vilka konsekvenser kommunaliseringen har medfört. I Professionens problematik analyseras motiven bakom kommunaliseringen. Historikern Johanna Ringarp visar att reformen var ett led i On 8 December 1989, the Swedish Parliament resolved that the state regulation of teaching positions would be terminated beginning on 1 January 1991. The parliament’s decision came on after fierce debates that took place in both teacher staff rooms and in public in 1989. Almost 20 years later, the reform still gives rise to controversy, and current political debates also touch on the possibility of

OBJECTIVE: To study intra-aneurysm sac pressure and subsequent abdominal aortic aneurysm (AAA) diameter changes in patients without endoleaks that remain unchanged in AAA diameter more than 1 year after endovascular aneurysm repair (EVAR). METHODS: A total of 23 patients underwent direct intra-aneurysm sac pressure (DISP) measurements 16 months (IQR: 14-35 months) after EVAR. Tip-pressure sensors

Popular Abstract in Swedish Den moderna tekniken att operera förslitna höftleder infördes av John Charnley i England på 1960-talet. Lårbenshuvudet ersattes med en metallkula på ett skaft och ledhålan på bäckenbenet med en skålformad plastkomponent. Bägge komponenterna sattes fast med en härdande plast, s.k. bencement. I början uppstod komplikationer med infektioner eller brott i själva protesen. DThis thesis focuses on the healing and remodeling of the morselized and impacted bone allograft, commonly used in revision of loosened hip prostheses with osteolysis. The influence on remodeling by the impaction procedure per se was analyzed, as well as the effects of endogenous bone graft proteins, and an exogenously applied growth factor (OP-1). A bone chamber model in rats was used, with the in

Denna studie undersöker och besvarar huruvida det är mer värt ur ett ekonomiskt perspektiv att renovera ett 50-talshus i originalskick än att bygga ett nytt hus när samma krav på inomhusmiljö ställs. Kraven ställs främst på luftkvalitén, men gäller även värmedistribution och levnadssätt. För att få en generell bild och ett resultat som kan användas i övergripande sammanhang har två alternativa utfThis study examines and answers whether it is more profitable from a financial point of view to renovate a 1950s house in its original condition than to build a new house when the same requirements are made regarding the indoor environment.

I studien undersöks i vilken grad och på vilket sätt läroboksuppgifter i fysik, genom sin utformning, främjar gymnasieelevers begreppsförståelse. Begreppsförståelsen definieras som elevernas förmåga att använda kunskapen i nya sammanhang. Studien betonar lärobokens viktiga roll i att forma elevernas förståelse. Uppgifter som främjar begreppsförståelse bör exempelvis vara varierade och knyta an tilTextbook tasks are a critical part of physics education as they build a wide range of skills necessary for mastering the subject.
