The effect of increased experience on complications in robotic hysterectomy for malignant and benign gynecological disease.
The study objective was to assess the effect of increased experience on complications in robotic hysterectomy for malignant and benign gynecological disease. This is a retrospective cohort study. It is a Canadian Task Force classification II-2 study conducted at the University Hospital, Sweden. The patients were 949 women planned for robotic hysterectomy for malignant (75 %) and benign (25 %) gyne
Ny trycksättningsmetod i trapphus för utrymning.
Mycket höga trapphus för utrymning kan trycksättas utan sektionering för att förhindra att brandgaser kommer in i trapphuset. Denna nya metod bygger på trapphusets ej försumbara strömningstekniska tryckfall och att trapphuset genomströmmas av ett flöde utöver det normala läckflödet som krävs för trycksättningen.

Environmental Modelling: Learning from Uncertainty
Environmental models are important tools; however uncertainty is pervasive in the modeling process. Current research has shown that understanding and representing these uncertainties is critical when decisions are expected to be made from the modeling results. One critical question has become: how focused should uncertainty intervals be with consideration of characteristics of uncertain input dat
Progressive, transgenerational changes in offspring phenotype and epigenotype following nutritional transition
Induction of altered phenotypes during development in response to environmental input involves epigenetic changes. Phenotypic traits can be passed between generations by a variety of mechanisms, including direct transmission of epigenetic states or by induction of epigenetic marks de novo in each generation. To distinguish between these possibilities we measured epigenetic marks over four generati

Polymorphisms, haplotypes and mutations in the protamine 1 and 2 genes.
Protamines are the most abundant nuclear proteins and alterations in their expression have been described in infertile patients. Also, protamine haplo-insufficient mice have been described as infertile. Therefore, the protamine 1 and 2 genes have been considered important candidates in different mutational studies. In this article, we review all published articles related to protamine gene mutatio
Radiative Properties of Rare Earth Elements - Free and Bound in Crystals
This thesis is devoted to fundamental aspects, and to spectroscopic applications of radiative properties in free atoms and ions, as well as in ions doped into crystals. Using the time-resolved laser-induced fluorescence technique, measurements of radiative lifetimes for rare earth elements have been performed in neutral Pr, Nd, Tm, and in singly ionized Sm, Er, Nd, Tm, Yb, as well as in doubly io

Doppler Audio Signal Analysis as an Additional Tool in Evaluation of Umbilical Artery Circulation
Purpose: To investigate the predictive capacity of a new method for sound spectrum analysis of Doppler signals recorded from the umbilical artery in high-risk pregnancies. Material and Methods: The retrospective study comprised 127 pregnant women with various pregnancy complications between 23 and 39 gestational weeks. Umbilical artery blood flow velocity waveforms were recorded with Doppler ultra

γ-Glutamyltransferase and Breast Cancer Risk Beyond Alcohol Consumption and Other Life Style Factors - A Pooled Cohort Analysis.
Elevated γ-Glutamyltransferase serum levels are associated with increased risk of overall cancer incidence and several site-specific malignancies. In the present prospective study we report on the associations of serum γ-Glutamyltransferase with the risk of breast cancer in a pooled population-based cohort considering established life style risk factors.
