Popular Abstract in Swedish GENETISK VARIATION OCH SEXUELL REPRODUKTION I EN MOSSA MED DVÄRGHANNAR, KALKLOCKMOSSA Mycket små hannar (dvs. dvärghannar) finns i flera olika djurgrupper men inom landväxterna bara hos mossor. Hos mossor uppstår dvärghannarna ifrån hansporer som landar och gror på honskottet där de inte blir större än några millimeter. Sporerna bildas inuti sporkapseln, som växer ut ifDwarf males occur in many unrelated groups of organisms. Among land plants they are unique to mosses. Moss dwarf males originate from male spores that land and germinate on the female where their final size is restricted to a few mm. Fertilization in mosses occur over short distances with swimming spermatozoids. Having the males growing as tiny epiphytes on the females facilitates fertilization, a

Background: Early blight, caused by the necrotrophic fungal pathogen Alternaria solani, is an economically important disease affecting the tuber yield worldwide. The disease is mainly controlled by chemical plant protection agents. However, over-using these chemicals can lead to the evolution of resistant A. solani strains and is environmentally hazardous. Identifying genetic disease resistance fa

Livets minsta byggstenar är celler (från latinets cella; litet rum). Hos encelliga djur, t. ex bakterier och jäst innehåller de enskilda cellerna allt som behövs för att leva och föröka sig. Hos flercelliga organismer är cellerna specialiserade och bygger tillsammans med andra specialiserade celler upp vävnader, organ och hela organismer. Gemensamt för alla celler är att de utvändigt omsluts av etAquaporins (AQPs) are membrane-bound intrinsic water channels that allow the passive diffusion of water and small solutes across cellular membranes. There are 13 highly conserved isoforms of these channels in human, which differ in specificity, regulation and localisation in cells and tissues. The work in this thesis focuses on AQP0 and AQP2; water-specific aquaporins that are known to interact wi

Preclinical studies on the role of erythropoietin (EPO) in bone metabolism are contradictory. Regeneration models indicate an anabolic effect on bone healing, whereas models on physiologic bone remodeling indicate a catabolic effect on bone mass. No human studies on EPO and fracture risk are available. It is known that fibroblast growth factor 23 (FGF23) affects bone mineralization and that serum

Cycling provides numerous benefits to individuals and to society but the burden of road traffic injuries and fatalities is disproportionately sustained by cyclists. Without awareness of the contributory factors of cyclist death and injury, the capability to implement context-specific and appropriate measures is severely limited. In this paper, we investigated the effects of the characteristics rel
