Tubes form the basic structure of several organs like lungs, kidneys, glandular organs like the pancreas, mammary and salivary glands. Tube formation involves a series of dynamic and interdependent cellular processes, including cytoskeletal reorganization, assembly of intercellular junctional complexes, and cell polarization. Understanding how cells polarize and coordinate tubulogenesis during org

Den här artikeln för fram digitaliseringen och konsekvenserna av Internet som ett studieobjekt med inneboende möjligheter för metodutveckling inom rättssociologi och den bredare rättsvetenskapen – vilket i sin tur adresserar en teoretisk potential. Artikeln lyfter fram tre aspekter som det argumenteras för är av särskild vikt att adressera: 1.) de stora datamängdernas och mätbarhetens metodologisk

Studies of non-model species are important for understanding the molecular processes underpinning phenotypic variation under natural ecological conditions. The common buzzard (Buteo buteo; Aves: Accipitriformes) is a widespread and common Eurasian raptor with three distinct plumage morphs that differ in several fitness-related traits, including parasite infestation. To provide a genomic resource f

The world supply and turnover of copper was modelled using simple empirical estimates and a COPPER systems dynamics model developed for this study. The model combines mining, trade markets, price mechanisms, population dynamics, use in society and waste as well as recycling, into a whole world system. The degree of sustainability and resource time horizon was estimated using four different methods

Breast cancer exhibits significant molecular, pathological, and clinical heterogeneity. Current clinicopathological evaluation is imperfect for predicting outcome, which results in overtreatment for many patients, and for others, leads to death from recurrent disease. Therefore, additional criteria are needed to better personalize care and maximize treatment effectiveness and survival.

Discussion of Zhang Yimou's film Coming Home.

Moths depend on pheromone communication for mate finding and synthetic pheromones are used for monitoring or disruption of pheromone communication in pest insects. Here we produce moth sex pheromone, using Nicotiana benthamiana as a plant factory, by transient expression of up to four genes coding for consecutive biosynthetic steps. We specifically produce multicomponent sex pheromones for two spe

Background: In European countries, knowledge about availability and utilization of support for informal caregivers caring for older persons (>= 65 years) with dementia (PwD) is lacking. To be able to evaluate and develop the dementia support system for informal caregivers to PwD, a survey of European support systems and professionals involved is needed. The aim of this study was to explore support

Lion fecal DNA extracts from four individuals each from Yankari Game Reserve and Kainji-Lake National Park (central northeast and west Nigeria, respectively) were Sanger-sequenced for the mitochondrial cytochrome b gene. The sequences were aligned against 61 lion reference sequences from other parts of Africa and India. The sequence data were analyzed further for the construction of phylogenetic t

Northern high-latitude wetlands are well known to seasonally emit methane gas into the atmosphere, and therefore contribute to greenhouse effects. While these gas emissions are well documented, their causes are not well understood. The method described in this work can be used to analyze the changes happening in the soil during gas emissions, and therefore help the understanding of the sub-surface

Popular Abstract in Swedish Det är känt att kvalitén på inomhusluften har en avgörande betydelse för folkhälsan bla avseende astma, eksem samt luftvägsinfektioner. Detta är ett för samhället mycket kostsamt problem. I avhandlingen har studerats vissa luftföroreningar inomhus som kan bli följden av att en byggnad drabbats av fuktskada. När fukt påverkar byggnadsmaterial frigörs och bildas en rad oUnsatisfactory indoor air quality (IAQ) may result from polluting emissions that are spread from building materials such as volatile organic compounds (VOCs) and/or microbial components or from various kinds of human activity such as smoking. Different methods are available to limit the exposure to unwanted pollutants and improve human wellbeing and health. One goal of this thesis was to determine

This paper presents a model of long waves and an empirical analysis of Swedish growth since 1850. The model emphasises the creation of new complementarities around macro innovations. The growth process is periodised in two main parts. The first period is characterised by transformation when development is uneven and unbalanced. The second period is characterised by rationalisation when the economy

There is an urgent need to start generating energy within cities in order to pave the way for a more sustainable and resilient society. Renewable energy by means of active solar energy systems (solar thermal, ST and/or photovoltaics, PV) can be generated using roofs and facades of buildings. In this study, the annual solar energy potential of typical Swedish city blocks was analysed in order to de

A dynamic model of forest ecosystems was used to investigate the effects of climate change, atmospheric deposition and harvest intensity on 48 forest sites in Sweden (n = 16) and Switzerland (n = 32). The model was used to investigate the feasibility of deriving critical loads for nitrogen (N) deposition based on changes in plant community composition. The simulations show that climate and atmosph

Effects of a dietary combination of omega-3 polyunsaturated fatty acids (n-3-PUFA) and conjugated linoleic acids (CLAs) on fasting and postprandial plasma lipids was investigated in healthy volunteers with different ages and body mass index (BMI). Lean (BMI 20-26 kg/m2) and obese (BMI 29-35 kg/m2), young (20-37 years) and older (50-65 years) men consumed 3 g/day each of CLA and n-3-PUFA or 6 g/day

Popular Abstract in Swedish Prostatacancer är den vanligaste formen av cancer hos män i Sverige och ungefär 10 000 män diagnosticeras årligen. Prostatacancer tros orsakas av en kombination av ärftliga faktorer och miljö-/livsstilsfaktorer. De enda väletablerade riskfaktorerna för prostatacancer är ålder, etnicitet och ärftlighet inom familjer. För att kunna arbeta med förebyggande av denna sjukdomProstate cancer (PCa) is a heterogenous disease including very aggressive lethal tumors to incidentally discovered clinically insignificant tumors. Age, ethnicity, and family history are the only established risk factors. Type 2 diabetes mellitus (T2D) has been found to associate with increased overall cancer risk but with lower risk of specifically PCa. T2D is initially associated with increased

A search for production of supersymmetric particles in final states containing jets, missing transverse momentum, and at least one hadronically decaying tau lepton is presented. The data were recorded by the ATLAS experiment in root s = 7 TeV proton-proton collisions at the Large Hadron Collider. No excess above the Standard Model background expectation was observed in 2.05 fb(-1) of data. The res

A search for single top-quark production via flavour-changing neutral current processes from gluon plus up- or charm-quark initial states in proton-proton collisions at the LHC is presented. Data collected with the ATLAS detector in 2012 at a centre-of-mass energy of 8 TeV and corresponding to an integrated luminosity of 20.3 fb[Formula: see text] are used. Candidate events for a top quark decayin

Objective. To compare the effects of a restrictive versus a liberal fluid prescription, on quality of life, physical capacity, thirst and hospital admissions, in patients who had improved from NYHA class (III-)IV CHF to a stable condition without clinical signs of significant fluid overload. Design. The present study is a randomised cross-over study. Seventy-four patients (mean age 70 +/- 10 years
