introduction: this study investigates to what extent the computed dose received by lung tissue in a commercially available treatment planning system (tps) for 192ir high-dose-rate breast brachytherapy is accurate in view of tissue inhomogeneities and presence of ribs. materials and methods: a ct scan of the breast was used to construct a patient-equivalent phantom in the clinical treatment plan...

Pharmaceuticals are emerging organic micropollutants that are frequently detected in the aquatic environment. While information on their environmental occurrence is substantial, knowledge gaps exist with respect to their environmental transformation. This licentiate thesis focuses on this research deficit by (1) providing and applying tools for identifying biotransformation products, and (2) in...

Men with either chronic or temporary urinary retention symptoms are common patients treated in a urology practice. Both indwelling and intermittent catheterization are widely used to treat this condition. These approaches are associated with significant complications including infection and reduced quality-of-life. Infection is a target for quality improvement and cost reduction strategies in m...

The notostracan tadpole shrimp (TPS) Triops newberryi Packard has potential to be used as a biocontrol agent of immature mosquitoes. Eggs, nymphal or adult shrimps are considered to be the stages for field introduction. To yield good growth of the shrimp and high production of shrimp eggs under artificial conditions, nutritional requirements of TPS for growth, survival and fecundity need to be ...

Antibody-secreting cells are generated in regional lymphoid tissues and traffic as plasmablasts (PBs) via lymph and blood to target sites for local immunity. We used multiparameter flow cytometry to define PB trafficking programs (TPs, combinations of adhesion molecules and chemoattractant receptors) and their imprinting in patients in response to localized infection or immune insults. TPs enri...

Trehalose and trehalose metabolism are crucial for insect development. We measured the content of polyhydric compounds in the hemolymph of diapause- and nondiapause-destined individuals of Helicoverpa armigera. We found that the trehalose content is much higher in diapause-destined individuals than that in nondiapause individuals. The activity of trehalose-6-phosphate synthase (TPS) during H. a...
