1. Thermal endometrial destruction by means of a balloon catheter : experimental and clinical evaluation of a new form of treatment for menorrhagia
Sammanfattning : Thermal endometrial destruction by means of a silicone balloon catheter is a new form of treatment for menorrhagia aimed at reducing menstrual blood loss. The purpose of the present work was to study, experimentally, the thermal effects on and the thermal conductivity of uterine tissue, to obtain a basis for the estimation of optimal treatment conditions by means of numerical analyses using a computer simulation model, to elucidate possible problems which may arise during the procedure, to evaluate how the patients tolerated this treatment and to judge which patients were suitable for this form of treatment and, finally, to study the uterine cavity after treatment and the long-term results of treatment.

2. Computer Aided Angioplasty : Patient-specific arterial modeling and smooth 3D contact analysis of the stent-balloon-artery interaction
Sammanfattning : Paper A: In this paper, the development and implementation of a contact algorithm based on C2-continuous surface representations is discussed. In 3D contact simulations involving models with arbitrarily curved surfaces (as in the case of vessel walls), the discretization of the contact surfaces by means of facet-based techniques could lead to numerical instabilities and finally loss of quadratic convergence.

3. Antibacterial effects of nitrite in urine
Sammanfattning : Urinary tract infections (UTI`s) are among the most common conditions causing individuals to seek medical care. In addition, catheter-associated infections account for most of the hospital-acquired UTI´s and is also a major source of resistant nosocomial pathogens. LÄS MER
4. Luminal nitric oxide : marker of intestinal inflammation
Sammanfattning : Nitric oxide (NO) is a pluripotent molecule with several important physiological functions in the human body. Large amounts of NO are released by various cell types during inflammation, although the role of NO in the inflammatory process remains unclear. LÄS MER
5. Factors of importance for labor induction
Sammanfattning : Background: What initiates the onset of labor is still not clarified, and it is debated whether expectant or active management is the best for the woman and the fetus. Active management means induction of labor (IOL) which is a very common obstetric intervention and is used in several situations. LÄS MER
