Contraceptive use and reproductive history in women with cervical human papillomavirus infection

Abstract in French Cette étude a été réalisée pour déterminer si les papillomatoses virales du col sont associées à l'utilisation des contraceptifs et aux antécédents de reproduction. Après avoir enregistré les antécédents de contraception et de reproduction de 972 femmes ayant demandé des conseils en matière de contraception, des examens ont été conduits pour dépister toute infection de papillomaThe study was conducted to investigate whether cervical human papillomavirus infections (CHPI) are associated with contraceptive use and reproductive history. The contraceptive and reproductive histories in 972 women seeking contraceptive advice were noted and screening conducted for human papillomavirus infection. The interview included number of pregnancies and childbirths, legal and spontaneous

Identification and Structure of High-spin Particle-hole States in 89Mo

Particle-gammagamma and gammagamma-coincidences of the reaction Ni-58(Ar-36, 4 pn)89Mo have been used to gain more information about high spin states in 89Mo and to establish the yrast sequence up to 7.6 MeV excitation energy and probable spin 37/2 h. Spins and parities were assigned on the basis of DCO-ratios measured with the OSIRIS spectrometer and a large volume Ge detector placed at 162-degre

Influence of the block length of triblock copolymers on th formation of mesoporous silica

The effect of different block lengths of Pluronic surfactants, (EO)(x)-(PO)(y)-(EO)(x), in the formation of mesoporous silica has been investigated. The syntheses were performed in micellar solution of the surfactant under acidic conditions. The materials were characterized by SAXS, TEM and nitrogen adsorption measurements. The EO-block length of the polymers determines the mesostructure of the si

Different quantities and quality of fat in milk products given to young children: effects on long chain polyunsaturated fatty acids and trans fatty acids in plasma.

In this study we compared plasma contents of long-chain polyunsaturated fatty acids (LC-PUFAs) and trans fatty acids in triglycerides (TG), phospholipids (PL) and cholesterolesters (CE) in young children fed milk diets containing different amounts of linoleic (LA) and alpha-linolenic acid (ALA). Because the diets differed in vitamin A and E content, plasma concentrations of vitamin A and E were al

A case study of successful e-learning: A web-based distance course in medical physics held for school teachers of the upper secondary level

Learning activities and course design in the new context of e-learning, such as in web-based courses involves a change both for teachers and students. The paper discusses factors important for e-learning to be successful. The development of an online course in medical physics and technology for high school teachers of physics, details of the course, and experience gained in connection with it are

A systematic overview of radiation therapy effects in head and neck cancer

A systematic review of radiation therapy trials in several turnout types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for head and neck cancer is based on data from 39 randomized trials and I

Isomeric States in the Light Tc Isotopes

Preliminary results from the first experiment of the Stopped Beam RISING campaign are presented. The relativistic projectile fragmentation of a 750 MeV/u beam of Ag-107 populated isomeric states in very neutron deficient nuclei at the proton dripline around mass 80-90. Nuclei were unambiguously identified using the FRagment Separator (FRS) and its ancillary detectors located at GSI. The ions produ

Fine and Ultrafine Particles from Combustion Sources - Investigations with In-situ Techniques

Popular Abstract in Swedish Det finns samband mellan halten av små luftburna partiklar och negativa hälsoeffekter i befolkningen. Målsättningen med avhandlingen var att utveckla och utvärdera metoder för in-situ karakterisering av fina (< 1 um) och ultrafina (Fine airborne particles are associated with adverse health effects in the human population. The aim of this research was to develop and evaluate methods for in-situ characterisation of fine and ultrafine particles and to determine their deposition in the human airways. The aim was also to increase knowledge about health and environmentally relevant properties of aerosols from biomass combustion an

Recruitment of resting stages may induce blooms of Microcystis at low N : P ratios

Some species of cyanobacteria form resting stages at the sediment surface when environmental conditions become unfavourable. As conditions turn more favourable, these resting stages hatch to the water phase, where the cells grow, reproduce, and sometimes form blooms. Since blooms of cyanobacteria have become an increasing threat to inland and brackish waters, it is important to assess the mechanis

An Essay on Copper Flat Axes

This dissertation can be read on at least two levels. On one level it will deal with- how general patterns of cognitive perception set frames for and affect human action in history and how these patterns may change. A study on copper flat axes will serve as a foundation for this discussion. This examination of copper flat axes will, however, at the same time examplify some of the problems concerni

Nonparametric Functional Estimation under Order Restrictions

This thesis consists of three papers (Papers A-C) on problems in nonparametric functional estimation, in particular density and regression function estimation and deconvolution, under order assumptions. Pointwise limit distribution results are stated for the obtained estimators, which include isotonic regression estimates, nonparametric maximum likelihood estimates of monotone densities, estimates

Fluctuating Asymmetry in Scabiosa canescens and Scabiosa columbaria: Association with Genetic Variation and Population Size

Developmental instability and fluctuating asymmetry (FA) have become important topics in evolutionary biology. For example, it has been suggested that FA could be a useful tool for identification of genetic and environmental stress factors. This study used plants from each of six populations of Scabiosa canescens and Scabiosa columbaria grown under greenhouse conditions. I tested whether there was

Postoperative pulmonary vascular supply in congenital heart disease evaluated with MR imaging at 0.3 T

The aim of this study was to investigate the usefulness of static spin-echo MR imaging at low field strength in evaluating postoperative pulmonary arterial supply. Twenty-seven patients operated on for complex congenital heart disease underwent cardiac MR imaging: 27 stenoses in 20 patients and 4 aneurysms were present in the material. Five of the overlooked stenoses were located in the ventricula

Differently charged polypeptides in the prevention of post-surgical peritoneal adhesions.

Objective. Peritoneal adhesions develop after almost all surgical interventions in the abdomen. We have developed an efficient treatment against post-surgical adhesions consisting of a combination of positively charged poly-L-lysine and negatively charged poly-L-glutamate. The aim of the present study was to further develop the concept of applying oppositely charged polypeptides in the prevention

Adolescent sexual offenders: a total survey of referrals to social services in sweden and subgroup characteristics.

Sampling methodology (e.g. population-based vs. clinical samples, anonymous self-reports vs. data collected as part of mandated treatment) affects the validity of conclusions drawn from research addressing the etiology of adolescent sexual offending. Studies of unselected samples allow testing of the generalizability of etiological models suggested from investigation of selected clinical or forens
