Background: Coffee consumption has been shown to be associated with various health outcomes in observational studies. However, evidence for its association with epithelial ovarian cancer (EOC) is inconsistent and it is unclear whether these associations are causal.Methods: We used single nucleotide polymorphisms associated with (i) coffee and (ii) caffeine consumption to perform Mendelian randomiz
Pilgrimstad in central Sweden is an important locality for reconstructing environmental changes during the last glacial period (the Weichselian). Its central location has implications for the Scandinavian Ice Sheet as a whole. The site has been assigned an Early Weichselian age (marine isotope stage (MIS) 5 a/c; > 74 ka), based on pollen stratigraphic correlations with type sections in continental
In the summer of 1922, fieldwork was conducted in the Tornedalen district of northern Sweden, in the immediate vicinity of the border with Finland. Three young men travelled together through the district on a motorcycle, documenting archaic buildings and villages in words and images. This documentation effort was part of a larger endeavour to survey and collect all the different aspects of what wa
In this paper a modified two-dimensional Luikov model for evaluating the non-isothermal moisture migration in porous building materials was proposed. The coupled heat and moisture transfer problem was modeled. Vapor content and temperature were chosen as the principal driving potentials. The coupled equations were solved by a numerical method, which consists of a finite difference technique with a
Many studies of children and apes realized in psychology address issues that are highly relevant to semiotics, but they often do so indirectly, or they use a terminology that is confusing and/or too vague from a semiotical point of view. The studies reported here, however, follow the paradigm of these psychological studies, but they are couched in an explicit semiotical terminology. They involve t
Adaptation is essential in maintaining stability during balance-challenging situations. We studied, ill standing subjects with eyes open and closed, adaptive responses of the anteroposterior head, shoulder, hip and knee movements: gastrocnemius and tibialis anterior EMG activity and anteroposterior body Posture when proprioceptive information from the neck or calf muscles underwent vibratory pertu
Aims: To examine biomarkers of oxidative stress (oxs), and endothelin (ET)-1, in hypertensive patients with atherosclerotic renal artery stenosis (ARAS) and to evaluate the effect of percutaneous transluminal renal angioplasty (PTRA). Methods: Baseline measurements were made immediately before renal angiography in patients with suspected ARAS (significant ARAS, n = 83, and non-RAS, n = 59) and in
Popular Abstract in Swedish Diabetes är en livslång kronisk sjukdom som före upptäckten av insulin 1922 ledde till döden inom 0-5 år från debuten vid ungdomsdiabetes, och inom ca 5-20 år vid åldersdiabetes. Användningen av insulin ändrade detta helt. Istället blev långtidskomplikationer ett hot som förkortade och påverkade livet. Förutom svåra infektioner handlar det om småkärlskomplikationer drab
In a recent publication, Feng et al. [Feng et al., Nat. Mater., 2015, 14, 61] reported a very interesting re-entrant solidification behaviour of colloidal particles in an aqueous solution containing polyethylene oxide (PEO). In this system, a crystalline colloidal phase, which is present at low temperatures, melts to a homogeneous fluid upon increasing the temperature. Further raising the temperat
Sorption of 75 active pharmaceutical ingredients (APIs) to three different types of sludge (primary sludge, secondary sludge with short and long sludge age respectively) were investigated. To obtain the sorption isotherms batch studies with the APIs mixture were performed in four nominal concentrations to water containing 1 g of sludge. The range of APIs concentrations was between ng L-1 to mu g L
Background: Patients and physicians both play an important role in the diagnosis of malignant melanoma. Objective: The purpose of this study was to assess important factors of delay in diagnosis at different centers and on three continents. Methods: Between October 2001 and October 2002, patients with histologically confirmed invasive melanoma were included in the study and given an established qu
Isolated Ca2+-binding EF-hand peptides have a tendency to dimerize. This study is an attempt to account for the coupled equilibria of Ca2+-binding and peptide association for two EF-hands with strikingly different loop sequence and net charge. We have studied each of the two separate EF-hand fragments from calbindin D-9k. A series of Ca2+-titrations at different peptide concentrations were monitor
Background: Daycare infants have more infectious episodes, see a physician more often, and are prescribed antibiotics more often than home care infants. Aim: To compare physician consultations and antibiotic prescription in daycare children and home care children taking number of symptom days, sociodemographic factors, concern about infectious illness and antibiotic knowledge into account. Methods
In the search for high efficiency combustion systems pulsating combustion has been identified as one of the technologies that potentially can meet the objectives of clean combustion and good fuel economy.Pulsating combustion offers low emissions of pollutants, high heat transfer and efficient combustion. Although it is an old technology, the interest in pulsating combustion has been renewed in rec
In this work, a first-order upwind and a high-order flux-limiter schemes for solving the advection–diffusion equation on unstructured grids were evaluated. The numerical schemes were implemented as a module of an unstructured two-dimensional depth-averaged circulation model for shallow lakes (IPH-UnTRIM2D), and they were applied to the Guaíba River in Brazil. Their performances were evaluated by c
As the number of new enteroviruses and human parechoviruses seems ever growing, the necessity for updated diagnostics is relevant. We have updated an enterovirus assay and combined it with a previously published assay for human parechovirus resulting in a multiplex one-step RT-PCR assay. The multiplex assay was validated by analysing the sensitivity and specificity of the assay compared to the res
A new understanding of the concept of health is needed to meet the goal of mental health nursing, which besides reducing disease is to strengthen the patient's health. The aim of the present study was to describe perceptions of the concept of health among nurses working in mental health services. Twelve Swedish nurses working in mental health services were interviewed and data were analysed with a
We have reported that epidermal Langerhans cells possess an H+-extruding mechanism signalling their existence in an anaerobic environment. This study highlights the energy metabolism of human epidermis. In their habitual state the keratinocytes contain more lactate than do most other cell types. Their lactate production in vitro is vigorous and independent of oxygen and most of it is released to t
