Case-control and cohort studies published between 1977 and 1988 were reviewed with the purpose to evaluate the relationship between use of oral contraceptives (OC-use) and breast cancer risk, tumour biology and tumour prognosis with special emphasis on early OC-use. the risk of breast cancer was assessed in 30 case-referent studies and 5 cohort studies, and the prognosis of breast cancer had been
In biomarker analysis, sample preparation plays a crucial step in order to extract, isolate and concentrate the analytes of interest. Among the various sample preparation techniques, solid phase extraction (SPE) is one of the most common and popular, due to the high enrichment factor, good recovery, low consumption of organic solvents and the possibility to automate (off- or on-line) the whole pro
The effect of mineral fertilization and its application pattern on microbial activity and the subsequent CO2 and CH4 emissions arising from soil organic matter (SOM) or added substrate remains unclear. We quantified the decomposition of 13C-labeled straw and the priming effect (PE) governed by the N and P fertilizer application pattern during a 100-day experiment in a flooded soil. Straw addition
Acoustic fatigue can occur in structural elements of an aircraft exposed to very high sound pressures. To deal with acoustic fatigue, mainly empirical methods have been applied and often late in the design phase. Current design guidelines have several limitations. First, they do not say anything about the load intensities. The load levels can be determined either experimentally or numerically. Exp
Background: Adequate sleep is crucial for children’s health, especially for children with ADHD and concurrent sleep problems. There is a need for more studies focusing on sleep problems in children with ADHD as these problems may exacerbate ADHD symptoms and vice versa, impacting negatively on everyday life. The aim of this study was to investigate the differences in health-related factors between
We investigated how the legacy of warming and summer-drought affected microbial communities in five different replicated long-term (>10 years) field-experiments across Europe (EU-FP7 INCREASE infrastructure). To focus explicitly on legacy effects (i.e. indirect rather than direct effects of the environmental factors), we measured microbial variables under the same moisture and temperature in a bri

Homeodomains are one of the key families of eukaryotic DNA-binding motifs and provide an important model system for DNA recognition. We have determined a high-quality nuclear magnetic resonance (NMR) structure of the DNA-binding homeodomain of the insulin gene enhancer protein Isl-1 (Isl-1-HD). It forms the first solution structure of a homeodomain from the LIM family. It contains a well-defined i
Huntington disease (HD) is a hereditary neurodegenerative disorder caused by an expanded cytosine–adenine–guanine triplet repeat in the huntingtin gene. The current diagnosis is based on the presence of typical motor signs in combination with a positive gene test. The motor onset of the disease is usually between 30 and 50 years of age, and the disease then progresses over around 20 more years. No
Postural tachycardia syndrome (POTS) is a chronic autonomic disorder characterized by excessive heart rate elevation upon standing or head-up tilt, in the absence of orthostatic hypotension. This debilitating condition affects primarily young to middle-aged individuals, particularly women, and substantially influences quality of life. The main presenting symptoms are lightheadedness, palpitations,
Every person diagnosed with tuberculosis (TB) needs to initiate treatment. The World Health Organization estimated that 61% of people who developed TB in 2021 were included in a TB treatment registration system. Initial loss to follow-up (ILTFU) is the loss of persons to care between diagnosis and treatment initiation/registration. LINKEDin, a quasi-experimental study, evaluated the effect of 2 in
Future wireless systems are envisioned to be able to deliver ultra-reliable and low-latency communication.The third generation partner project (3GPP) has identified three different usage scenarios such as enhanced mobile broadband, massive machine-type communication, and ultra-reliable low latency communication.In each of those scenarios, several services and applications can be implemented, e.g.
The aim of the first this work part of the EU-project, Trial I, was to evaluate and possibly improve the CEC image criteria for radiographic chest images. Chest images of healthy volunteers were acquired using different technique factors. The image criteria were used as a tool to discriminate between the different images. The technique factors were chosen so that the image quality would differ sli
Background: An epidemic of chronic kidney disease of unknown cause has emerged along the Pacific coast of Central America, particularly in relatively young male sugarcane workers. In El Salvador, we examined residence and occupations at different altitudes as surrogate risk factors for heat stress. Study Design: Cross-sectional population-based survey. Setting & Participants: Populations aged
An organization aiming to survive on a more challenging or changing market has to adapt or fundamentally change the way it is doing business. For the Swedish forest products industry, and more specifically the paper packaging industry, the market challenges range from saturated home markets, competing materials and increasing production costs, to growth of new markets and more powerful actors in t
Beijing has been experiencing severe particulate pollution accompanying the fast growing population and economy. This study investigated the impact of PM2.5 and its water soluble organic and inorganic constituents on visual impairment in Beijing under different meteorological conditions. According to the analysis of PM2.5 samples collected in Spring 2012, water soluble species took up 38.1% of PM2
Sammanfattning I uppsatsen har syftet med 3:12-reglerna, särskilt utomståenderegeln i 57 kap. 5§ IL, framställts och analyserats. Därjämte studien har ägnats åt att undersöka hur praxis stämmer överens med utomståenderegelns ändamål. Metoden som har tillämpats är den rättsdogmatiska metoden, vilket innebär att undersökningen genomförs med hjälp av rättskällorna så som förarbeten, författning, praAbstract The purpose of the essay is to describe and analyze the motive that was behind the 3:12 rules, especially the outsider rule, and to examine how practice is consistent with its purpose. The main starting point for the regulations in question was that the taxpayer who owns shares and works in the company should, as far as possible, receive similar taxation for capital gains or work compens
Estimating area of polygons on the Earth’s surface is required in many fields in earth science. In the field of carbon modelling, one application of estimating polygons’ area is to estimate carbon flows for regions. This thesis aims to develop a methodology to estimate area of a polygon on a spherical/ellipsoidal surface applied to the problem to estimate carbon flows in regions. It is common th
