1. Endosonography and pretreatment tumor profiling - from sampling, staining, to sequencing
Sammanfattning : Background and aims: Endosonography-guided fine needle aspiration (EUS-FNA) is imperfect in diagnosing solid pancreatic lesions (SPL) and subepithelial lesions (SEL) including gastrointestinal stromal tumors (GIST). In GISTs, imatinib therapy is effective only in variants of oncogenes KIT and PDGFRA. LÄS MER
2. Improved hydrogene peroxide bleaching of mechanical pulps through fundamental understanding of the influence of heat, iron, fines and chemical treatment on chromophore content

3. Purification, Stereoisomeric Analysis and Quantification of Biologically Active Compounds in Extracts from Pine Sawflies, African Butterflies and Orchid Bees
Sammanfattning : Stereochemistry plays an important role in nature because biologically important molecules such as amino acids, nucleotides and sugars, only exist in enantiomerically pure forms. Semiochemicals carry messages, between the same species (pheromones) and between different species (allelochemicals). LÄS MER
4. Lung Function, Respiratory Muscle Strength and Effects of Breathing Exercises in Cardiac Surgery Patients
Sammanfattning : Background: Breathing exercises are widely used after cardiac surgery. The duration of exercises in the immediate postoperative period is not fully evaluated and only limited data regarding the effects of home-based breathing exercises after discharge from hospital have been published.
